CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims the benefit of priority to Indian Patent Application No. 1867/DEL/2010, filed on Sep. 24, 2010, the disclosure of which is hereby expressly incorporated by reference in its entirety. 
       FIELD OF THE INVENTION 
       [0002]    The present invention describes novel “air rich fabric” and “air rich yarns” with pores throughout the cross-section. The present invention also describes the process for manufacturing air rich fabrics and yarns. In particular, the invention is directed at producing air rich fabrics and yarns which have high wettability, easy dryability, quick absorbency and increased thickness. The air rich fabrics having increased thickness have added advantage of keeping the body warm as they do not allow the body&#39;s heat to transmit easily through the fabric. 
       BACKGROUND 
       [0003]    Fabric is a flexible material consisting of a network of natural or artificial fibers often referred to as thread or yarn. Yarn is produced by spinning raw fibers such as wool, linen, cotton, or other natural or manmade material on a spinning wheel to produce long strands. Fabrics are formed by weaving, knitting or by non-woven techniques. 
         [0004]    The fabrics woven and terry woven are made from, for example, 100% cotton fiber yarns, fiber blends in yarns like: cotton and viscose, blends of cotton and modal, blends of silk and modal; bamboo fiber yarns; and blends of cotton and bamboo yarns. 
         [0005]    Flat fabrics, such as sheeting or apparel, may be made from 100% cotton; blends of polyester and cotton; blends of polyester and viscose; blends of cotton and modal; blends of cotton, silk and modal; and any combinations thereof. 
         [0006]    Further, most fibers have absorbent properties but the extent of absorption depends on the type of fiber, nature of yarn used and the design of the fabric etc. 
         [0007]    However, by suitable modifications in the yarn structure, it is possible to increase the wicking property of the yarn, in effect increasing the hydrophilic nature, thereby making the yarns quick absorbing and bulky. 
         [0008]    Terry Towels are generally thick materials. The thicker the towel, the greater the surface area, and thus a greater amount of water can be absorbed. When a towel fabric encounters a water droplet, the pile loops first remove the droplet by sucking the droplet between the space available among the pile loops and then absorbing the water inside the yarn in the space between the fibers in the yarn. The latter part applies to flat fabrics as well. The absorbed water then enters the secondary wall and in lumen of the cotton fiber. 
         [0009]    The amount of twist in the yarn affects the properties of the towel products. The pile yarn is generally a low-twist yarn. Pile loops provide maximum surface area for the absorption of water, and the low twist aids in the absorption by imparting wicking properties to the yarn. Ground warp and weft are generally hard-twisted compared to the pile yarn. The ground and weft yarn twist factors generally range from about 3.8 to about 4.2, depending upon the towel construction. In contrast, the twist factor in the pile yarn generally ranges from about 3.2 to about 3.9. Similarly in the case of flat fabrics the twist factor for warp and weft range from about 3.8 to about 4.5. 
         [0010]    The yarns normally used in terry fabrics are coarse and range from Ne (Number English) 8s to 30s in single as well as doubled configuration for pile, weft and ground yarns. 
         [0011]    Similarly the warp and weft yarn count, in the case of flat fabrics range from Ne. 12s to Ne. 100s in single as well as doubled configuration depending on the construction of fiber, their blends and the structure of the yarn made thereof. 
         [0012]    Decorative designs and embellishments are formed using polyester filament, polyester spun yarn, viscose filament yarn, viscose spun yarn, mercerized cotton yarn, cotton linen fiber blended yarns, Ramie cotton fiber blended yarn, modal fiber yarns, chenille yarn, modified viscose fiber yarn, and combinations thereof. Other flat fabrics such as sheeting or apparel are made from 100% cotton fiber yarn; fiber blends of polyester and cotton; blends of polyester and viscose; blends of cotton and modal, blends of cotton and silk and modal; blends of cotton and bamboo; blends of cotton and sea weed fibers; blends of cotton and sliver fibers; blends of cotton and charcoal fibers; and any combinations thereof. 
         [0013]    The greater the amount of free air space available within the yarn, the quicker and higher absorption of the water. Hence, to increase the amount of free spaces, (as the air space increases, the drying of the towel after absorption also increases) structural changes in the yarn have to be made. 
         [0014]    Polyvinyl alcohol (“PVA”), a man made fiber, has the unique property of dissolving in hot water. Earlier invention(s) exploits the dissolving property of PVA by introducing PVA into blended yarns and, for example, in core of the cotton yarn. 
         [0015]    There are various methods of introducing PVA into cotton yarn via cotton spinning system. These methods have been exploited earlier. These methods are: 
         [0016]    a) Inserting PVA fibers into the core during ring spinning, by inserting PVA spun yarn into the stream of cotton fibers in the drafting zone during ring spinning on Ring Frame. 
         [0017]    b) Blending the PVA roving with the cotton roving during feeding in the drafting system of ring frame in SIRO spinning system. 
         [0018]    c) Inserting PVA fiber slivers into the middle of cotton slivers at the feeding end of the drafting zone of the speed frame, twisting on the speed frame, and subsequently spinning the yarn at ring spinning. 
         [0019]    d) Blending PVA fiber along with cotton fiber in the initial process of fiber mixing in cotton spinning system. 
         [0020]    e) Doubling PVA yarn with cotton yarn with twist in reverse direction of cotton yarn leaving the final finished fabric with cotton yarn having only few turns of twist. 
         [0021]    By using methods (a), (b) and (c) the blend homogeneity, across the radial direction in the final yarn structure, can not be ascertained. Also, by using these methods well interlinked ‘through pores’ through out the cross section of the yarn and on the surface of the yarn cannot be achieved. The pores formed are mainly of ‘closed’ and ‘blind’ type. The yarn made by these methods may be hollow in core but the surface is covered. Covered surface does not allow water to go inside the core in hollow space so easily. These methods are thus, not effective to attain the porous yarn structure in the final fabric. The structural difference in these yarn structure and invented can be well understood from schematic diagram in  FIG. 1 . 
         [0022]    By using process (d) porous yarn structure in the final fabric can be attained. This process has operational challenges in blended process due to entirely different processing behavior of PVA fibers. 
         [0023]    Process (e) involves separate spinning process for PVA yarn and Cotton Yarn. Therefore an additional cost of doubling process with PVA yarn is added making the process cost ineffective. Also structure of the yarn is open fiber structure which causes negligible binding of the fibers. 
         [0024]    Thus, there is a need for an economic and cost effective process of manufacturing air rich fabric/yarns with pores throughout the cross section. 
       SUMMARY OF THE INVENTION 
       [0025]    An object of the present subject matter is to provide a method for manufacturing fabrics, which are highly wettable, easily dryable, quick absorbing, thicker (voluminous). The fabrics have an added advantage of keeping the body warm and not allowing the body heats to transmit easily from the fabric (herein referred to as “Air rich fabrics”). 
         [0026]    Another object of the present subject matter is to provide a method for manufacturing Terry fabrics that can absorb about 75% to 100% of the water contacting them and dry with a drying rate 10 to 30% faster than normal fabric. 
         [0027]    Yet another object of the present subject matter is to provide Air rich fabrics/yarns with pores through out the cross section and on the surface as well. 
         [0028]    To achieve the said objectives, this invention provides a process of manufacturing Air rich fabrics. The process involves blending water soluble fibers (e.g. PVA fibers) with the base fibers (e.g. cotton fibers). Modified method of blending water soluble fiber slivers along with base material fiber slivers on the draw frame of a spinning system. Further, giving one more draw frame passage for achieving the blending homogeneity in radial direction. This method helps in achieving pores through out the surface of the final yarn and making the porous yarn structure in the final fabric stage. 
         [0029]    The process used in the present invention simplifies the processing of water soluble material fiber blended with base material fiber and eliminates the cost of manufacturing water soluble material roving or yarn.

       DETAILED DESCRIPTION 
       [0056]    The present invention relates to novel air rich fabric/yarns with pores throughout the cross-section. The process of making air rich fabric is also described. The process basically comprises the following steps: 
         [0057]    a) Blending water soluble material slivers with the base material slivers in the draw frame to obtain blended slivers; 
         [0058]    b) Drawing the blended slivers obtained in step (a) till homogeneously blended strands are obtained; 
         [0059]    c) Pre spinning the homogeneously blended strand obtained in step (b) to obtain well blended roving; 
         [0060]    d) Spinning the well blended roving obtained in step (c) to obtain yarns; 
         [0061]    e) Weaving or knitting fabric using yarns obtained in step (d) as at least one of the component; 
         [0062]    f) Treating the fabric obtained in step (e) with water to dissolve out water soluble component to obtain fabric with pores; 
         [0063]    g) Optionally Dying the fabric obtained in step (f) to obtain dyed fabric; and 
         [0064]    h) Optionally Post treating dyed fabric obtained in step (g). 
         [0065]    The fabric is washed in warm water to dissolve the water soluble fibers. The amount of fibers dissolved, depends upon the count of the yarn or yarns used. The amount of water soluble fibers present can vary from about 8% to about 25% of the weight of the yarn. For example, water soluble fiber may be present as 8%, 10%, 12%, 14%, 15%, 16%, 18%, 20%, 22%, or 24% of the weight of the yarn. By dissolving the water soluble fibers, additional air spaces are produced on the structure of yarn, corresponding to an increase in the airspace in the yarn. By increasing the through pores in the yarn, the resulting fabric (e.g. towel) is softer and bulkier than standard cotton fabric (e.g. cotton towel) having good water permeability and drying properties. 
         [0066]    The terry fabrics and yarns of the present invention can absorb, for example, between about 75% and 100% of the water contacting the yarn or fabric (Amount of water as per Test Method ASTM D4772). In a preferred embodiment, the air rich yarns and towel fabrics of the present invention can absorb between about 75% and 100% of the water contacting the yarn or towel fabric. In another embodiment the air rich fabrics can absorb more than 75% of the water contacting the yarn or fabric and dried at a rate 10 to 30% faster than the normal yarn or fabric. In yet another embodiment the porous yarns and fabrics are 30 to 40% more voluminous than the normal and have 20 to 30% higher thermal insulation properties. 
         [0067]    The air rich yarn herein described typically contains base material fibers and a fiber, which dissolves in warm water i.e. water soluble fibers, such as PVA (Polyvinyl Alcohol). 
         [0068]    The air rich yarn is used in the pile of the towel or toweling fabric. Whereas in the case of a flat fabric, such as sheeting, warp and/or weft yarn can be air rich yarn. 
         [0069]    Air rich pile yarn is woven with base material weft and warp yarns to produce terry fabrics, such as towels. The fabric is then washed in warm water to dissolve water soluble fibers. The amount of water soluble material present can vary from about 8% to about 25% of the weight of the yarn. For example, the PVA may be present as 8%, 10%, 12%, 14%, 15%, 16%, 18%, 20%, 22%, or 24% of the weight of the yarn. By dissolving the water soluble fibers, additional air spaces are produced on the structure of pile yarn, corresponding to an increase in the airspace in the pile yarn. By increasing the through pores in the pile yarn, the resulting towels are softer and bulkier than standard cotton towels having good wettability and drying properties. 
         [0070]    In the case of flat fabrics the air rich warp and/or weft yarn similarly contain warm-water soluble fibers, such as polyvinyl alcohol (PVA) fibers, in the structure of the cotton yarn and/or other fibers as base material. 
         [0071]    The cotton that may form the major component of surface of the pile yarn or warp-weft yarn can be of any origin; for example, Indian, Egyptian, Australian, United States of America (USA), Syria, or Russia. 
         [0072]    The water soluble fiber used can be PVA. The properties of fibers available for manufacture of spun PVA yarn are given below in table 1.

         [0073]    In specific embodiments: The process of manufacturing air rich fabric comprises the following steps and can be understood with reference to  FIG. 2  and  FIG. 3 : 
         [0000]    Producing Water Soluble Material Slivers from Water Soluble Fibers— 
         [0074]    The water soluble material fibers (e.g. PVA fibers) are first processed through a blow room in the cotton spinning system. In spinning process the fibers are made into slivers through the process of carding and use of a draw frame (one or two passages as required in order to ensure uniformity of fibers in the stream). The range of water soluble material sliver hank is from 0.05 to 0.40s Ne. 
         [0075]    A water soluble material fiber sliver is made on the draw frame with a finer hank greater than or equal to 0.05 hank. The denier of the water soluble material fibers is typically from about 0.9 to about 2.2 denier. It can have a cut length that is equal to or more than 32 mm and equal to or shorter than 51 mm (44 mm and 51 mm fiber can be used with modifications in the machine parameters in spinning). 
         [0000]    Producing Base Material Slivers from Base Material Fibers 
         [0076]    The base material sliver may be made from, for example, different cotton blends, silk fibers, modal fibers, acrylic fibers; blends of cotton and bamboo; blends of cotton and sea weed fibers; blends of cotton and sliver fibers; and blends of cotton &amp; charcoal fibers. The warp-weft yarn in flat fabrics may have blends of, for example, polyester and cotton; blends of polyester &amp; viscose; blends of cotton and modal; blends of cotton and silk and modal; blends of cotton and bamboo; blends of cotton and sea weed fibers; blends of cotton and silver fibers; blends of cotton and charcoal fibers, and any combinations thereof. In case of blended sliver, each component is separately processed through carding/combing and the individual carded slivers are subsequently blended together on draw frames. 
         [0077]    The cotton sliver is prepared by processing through the blow room, carding, draw frame, combers, and final draw frames, producing a 0.05 hank sliver and above. 
         [0078]    After carding, the cotton sliver is subjected to combing to remove short fibers. The amount of noil, or fibers that are less than 12 mm, removed, ranges from 7% to 24% of the weight of the feed material. For example, the weight removed can be 8%, 10%, 12%, 15%, 16%, 18%, 20%, 22%, and 24% of the weight of the feed material. 
         [0000]    Blending Water Soluble Material Slivers with the Base Material Slivers 
         [0079]    It involves blending water soluble material slivers with base material slivers in the draw frame of a cotton spinning system. Further, giving one or more draw frame passages for achieving the blending homogeneity in radial direction is the ideal method of achieving through pores on the surface of the final yarn and making the porous yarn structure in final fabric because water soluble fibres are uniformly distributed in the structure of the yarn. This is quite different from the normal “PVA based absorbent” yarn where PVA fibres are their in the core of the yarn and goes off only from the core in final finishing stage making core hollow with so called closed or blind pores not the whole structure porous with through pores. 
       Pre Spinning the Homogeneously Blended Strand 
       [0080]    It involves drawing the homogeneously blended strand to roving form and making a twisted roving on speed frame. In conventional terminology this process step is termed as pre spinning which prepares the material for the final yarn spinning. 
         [0081]    The twisting of the roving with the PVA fibers in the structure is done in the normal fashion, i.e. with clockwise rotation of the flyer to give ‘Z’ twist. Alternatively, the roving can have ‘S’ twist, by reversing the direction of the rotation of the flyer to a counter-clockwise direction. 
         [0082]    The roving produced by these methods has a twist multiplier to optimize the working conditions. The roving hank ranges from about 0.5 to about 3.0 hanks. 
       Spinning the Well Blended Roving 
       [0083]    The Air rich yarn is spun on the ringframes using the preferred blend settings, for example, all of the setting parameters on ringframe are determined based on the type of water soluble material and other base materials used to make the yarn. The yarn spun on the Ring Spinning has a count ranging from about Ne 7s to about 32s for terry fabrics and about Ne.10s to about 100s for flat fabrics. Where doubled yarn is to be made, two single yarns are doubled on two-for-one twisters with a TPI(twists per inch) from about 5.5 to about 16.5 TPI in ‘S’ direction. The twist direction can be Z over S or Z over Z. The resultant counts would be about 2/7s to about 2/32s, for terry fabrics. Similarly the doubled yarns for flat fabrics may be from about 10/2s to about 100/2s with about 50% to about 85% of single yarn TPI as doubled yarn TPI in either Z over S or Z over Z configuration. The cut length of the water soluble material (PVA) fibers is about 32 mm, 38 mm and 44 mm (with longer middle cradle in the drafting zone) which can be used for spinning in the cotton system. The machinery settings depend on the fiber length and the settings will be as per the recommendation of the machine manufacturer for these lengths. For the coarser count the same water soluble material (PVA) blended sliver can be used on OE spinning system to make the porous yarn for towel, rugs and carpet fabric. OE stands for Open End (OE) spinning, a different spinning technique of making yarn other than the ring spun yarn, where in the yarn is made directly from sliver by using rotor-spinning technology. 
         [0084]    The processing parameters depend on the water soluble material fiber and base material used and/or other fibers used in the blend. The ring spun yarn is wound into large packages on the Autoconer using suitable settings and process parameters 
       Weaving or Knitting the Yarns to Obtain Fabric 
     A) Terry Fabric 
       [0085]    Woven Terry fabrics (e.g. terry towels) are formed from three types of yarns: 1) Ground Warp 2) Weft 3) Pile Warp. The first type of yarn is the ground warp. The ground warp is the longitudinal set of yarn forming the base for fabric. The second type of yarn is weft yarn. Weft yarn is perpendicular to ground yarn and interlace with ground yarn to make a base fabric. Ground and Weft yarn form a base fabric in which third type of yarn pile is hold in the form of loops. These loops are protruding outward and contributing to thickness and bulk of fabric. These yarn are meant for absorbing water from surface e.g. when used during bath. 
         [0086]    The Ground yarn has a single or double count. Double count range from about Ne 2/12s to about Ne 2/30s and single count from about Ne10s to about Ne 16s combed or carded. Yarn can be made using any spinning technique e.g ring spinning, open end spinning etc. In the preferred embodiment, the ground yarn is about 2/20s carded ring spun. 
         [0087]    The weft yarn, has a count ranging from about Ne 7s to about Ne 30s generally both carded/combed made with any spinning technique e.g Ring Spinning, Open End Spinning etc. In the prescribed embodiment the weft is about Ne16s carded ring spun yarn. 
         [0088]    The Pile yarn has a single or double count. Double count range from about Ne 2/16s to about Ne 2/30s and single count from about Ne 7s to about Ne 32s combed or carded. Yarn can be made using any spinning technique e.g ring spinning, open end spinning etc. In the preferred embodiment, the pile yarn is about 13s Combed ring-spun made with Air Rich Technique and comprises water soluble material fibers. 
         [0089]    The Twist Multiplier for weft yarn and ground yarn is from about 3.4 to about 5.4 Z twist generally depending upon fiber and spinning technique. 
         [0090]    The ground, weft, and pile yarns are woven together. The terry fabric is generally made on 56s, 60s and 70s reeds; however, reed is not a limiting factor. 
         [0091]    The terry weave can be 3 pick terry, 4 pick terry, 5 pick terry, 6 pick terry. The pile height can range from about 2.5 mm to 10 mm. Most common is 4 mm to 6.5 mm. 
       B) Flat Fabric 
       [0092]    Flat fabrics are woven with air rich warp and/or air rich weft yarn. The fabric construction depends on the end use and type of fabric to be made. 
         [0000]    Treating the Fabric with Water 
         [0093]    Water soluble Fibers (PVA fibers) are dissolved out during dyeing or before dyeing at temperature depending upon the type of water soluble material used. However, the temperature for dissolving PVA fibers ranges from 40 Deg C. to 110 Deg C. depending on type of PVA fiber, dyeing machine, liquor ratio and cycle time. 
         [0094]    The liquor ratio is a ratio of the material weight (Fabric) to water (Volume). The liquor ratio should be sufficient to facilitate prompt dissolution of the PVA, while allowing free movement of the fabric. The liquor ratio ranges from about 1:4 to about 1:30. For example, the liquor ratio may be 1:7, 1:12, 1:15, 1:20, 1:25, 1:22, or 1:28. This depends on dyeing machines technology/setup available. In the preferred embodiment the liquor ratio is 1:4.5 which is considered as lowest in exhaust batch dyeing process in soft flow machines. In general liquor ratio used 1:7 in soft flow exhaust batch dyeing machines. In case dyeing is carried out in winch or Jigger machines material to liquor ratio is as high as 1:20 
         [0095]    In order to make air rich product, water soluble fiber has to be removed completely. The product Quality is independent of liquor ratio. 
         [0096]    In another embodiment, after washing, the liquor is drained and fresh water is injected for rinsing to eliminate all the dissolved PVA. The water is at a temperature ranging from about 55 degree Celsius to about 100 degree Celsius. Preferably, the water is at a higher temperature, such as 100 degree Celsius. Therefore, the fabric is rinsed in hot water after draining to wash away any PVA residue. This rinsing step also ensures that any loose fibers drain out along with the drain water. 
       Dying &amp; Post Treatment 
       [0097]    After dissolving the water soluble material the fabric is dyed with normal dyeing process which is scoured, bleached and dyed in the normal fashion in a fabric dying machine. While scouring, bleaching and dyeing, the operating temperature ranges from about 60 degree Celsius to about 110 degree Celsius. However, temperature for dissolving PVA ranges from 50 Deg C. to 100 Deg C. depending on type of PVA fiber. 
         [0098]    The liquor ratio is a ratio of the material weight (Fabric) to water (Volume). The liquor ratio should be sufficient to facilitate prompt dissolution of the PVA, while allowing free movement of the fabric. The liquor ratio ranges from about 1:4 to about 1:30. For example, the liquor ratio may be 1:7, 1:12, 1:15, 1:20, 1:25, 1:22, or 1:28. In the preferred embodiment the liquor ratio is 1:4.5 
         [0099]    Air rich product quality is not dependent on dyeing process. If PVA or other water soluble fiber is removed properly during or before dyeing the yarn and thus the product becomes Air Rich and improved properties i.e better wettability, higher thickness, faster drying, better absorbency are achieved. 
         [0100]    After washing, the liquor is drained and fresh water is injected for rinsing to eliminate all the dissolved PVA. The water is at a temperature ranging from about 55 degree Celsius to about 100 degree Celsius. Preferably, the water is at a high temperature, such as 100 degree Celsius. The PVA coagulates during the dissolving step and promptly dissolves in hot water if the high temperature is not maintained. Therefore, the fabric is rinsed in hot water after draining to wash away any PVA residue. This rinsing step also ensures that any loose fibers drain out along with the drain water. 
         [0101]    After dyeing or washing fabric has to be dried. There are several ways for drying the fabric. In present embodiment, drying is done through hydro extractor, rope opener, loop dryer and stenter. Gradual drying leads to better hand feel. 
         [0102]    The method of processing can also be continuous bleaching and continuous dyeing range followed by hot air drying and stentering. Care is to be exercised to ensure that the PVA dissolves completely, during the process.

       Example 1 
     Pile Yarn Manufacturing, Towel Manufacturing, and Processing 
       [0104]    The PVA fiber used in this example is 1.4 denier 38 mm fiber and S6 cotton of Indian origin with 2.5% span length of 28 to 32 mm, micronaire of 3.9 to 4.9, fibre strength of 28 Gtex to 30 Gtex, and short fibre index 3.5 to 6.5%. The cotton and PVA fibers were blended to produce a pile yarn containing 85% J 34 Combed Sliver (18% Noil) and 15% PVA (1.4 denier).

         [0107]    The cotton is processed through blowroom having bale plucker, vario clean, unimix, and ERM beater. 
         [0108]    The cotton is processed from blowroom through to carding where the fibers are individualized. The hank of the card sliver is maintained at 0.1 delivered from machine at speed of 145 meter/minute. 
         [0109]    The cotton sliver from carding is then processed through a beaker drawing where at the feed end the number of doublings are 6 and a hank delivered kept at 0.12. The delivery speed is 450 mtrs per minute. 
         [0110]    Since combing is necessary to remove short fibers, the drawframe slivers are processed through unilap machine with 24 doublings and formed into a lap of 75 gms/meter at a delivery speed of 120 metres/min. 
         [0111]    The lap is processed on combing machine with 8 heads and one delivery resulting in a hank of 0.10. The combers worked at 350 nips/min with a backward feed of 5.2 mm per nip. The extracted noil is 18%. 
       PVA Sliver Preparation 
       [0112]    The PVA fiber used is 38 mm*1.4 denier. The PVA fibers are first passed through blowroom having a feeder and a MBO beater only. This is because the PVA fiber is the manmade fiber and is clean without any impurities. 
         [0113]    The PVA fibers from Blow Room goes to the carding machine where the cards are run at 100 meters/minute delivery speed and a hank of 0.12. On the card the flat speeds are kept low at 90 to 110 mm per minute to minimize wastage. 
         [0114]    The card sliver (PVA) is then processed through leveling drawframe, with 6 ends up and a delivery hank of 0.11. The machine runs at 300 meter/minute. 
       Blending on Draw Frame 
       [0115]    A blending passage drawing with 5 ends up of combed cotton sliver and one leveled sliver was doubled at 200 metres/min speed a delivery hank of 0.11 is given for mixing and making the fibers more parallel with one another. 
         [0116]    During the feeding of slivers in blending draw frame the PVA sliver remains in the centre of the cotton slivers 
         [0117]    8 blended sliver is again doubled and drafted on the finisher draw frame for making the resultant sliver which is having uniform transverse and longitudinal blend of cotton and PVA fibre. The hank of delivered sliver was 0.11s Ne and delivered through autolevelled (for insuring the mixing of two components in the final sliver) draw frame at a speed of 250 metre/min) 
         [0118]    The fibres in the delivered sliver are parallel, straightened and well mixed across the radial and longitudinal direction 
         [0119]    The Finisher Draw Frame 
         [0120]    PVA and cotton blended sliver cans are kept at the feed end of the speed frame and a roving of 0.5 hank is delivered after drafting and twisting of feed sliver. The hank of roving delivered was 0.5s Ne. 
         [0121]    The following table enumerates the properties of the preferred embodiment Ne 13s Air rich yarn with PVA/cotton in the structure.

         [0124]    The towels with air rich yarn in the pile and cotton yarn in weft and ground is processed in the dyeing house in the rope form. The dyeing process comprises of dissolving PVA followed by normal cotton dyeing process (if base material is cotton). PVA dissolving is done at 100 deg C. for 10 min in soft flow machines. The water is drained and pretreatment is started. Pretreatment comprises of bleaching and scouring. It is done in one step using caustic lye and hydrogen peroxide. Dyeing is as the standard cotton dyeing process for reactive dyeing. After dyeing, softeners are added in acetic medium in order to regain softness of the cotton fiber. Softeners used in terry toweling are silicon based, hydrophilic so that absorbency due to softener does not reduce. 
       Examples 2 to 7 provide the process parameters of processes used for manufacturing air rich yarns using various base materials and water soluble materials. Table 5 below provides brief descriptions of the said processes.
