TEXTILE AND GARMENT COMPRISING A DUAL- WEAVE OF
[0001] The present invention relates to a textile and garment comprising a dual-weave of composite materials. In particular, this invention relates to a textile and garment comprising a dual weave of composite materials comprising cotton and ultra high molecular weight polyethylene (UHMWPE) and optionally elastane.
[0002] Knit fabrics are one of the oldest and maybe the easiest way of producing a fabric. In a knit fabric the yarns make loops around each other, with the looping causing bending which results in softer fabrics that have greater volume than standard woven fabrics. Generally, knit fabrics are much softer and more flexible than woven fabrics. However, the fabric stability or shape retention is not as good as in woven fabrics. Therefore, knit fabrics are used in topswear like jumpers or sweatshirts or t-shirts or for bottoms in more sportive fields like sweatpants due to their softness and comfort.
[0003] A woven fabric is obtained by crossing weft yarns and warp yarns, in a weaving pattern whereby the weft yarns extend over and below one or more warp yarns to provide, with respect to the warp yarns, correspondent over portions and under portions.
[0004] Denim is a popular fabric that is produced by weaving weft and warp yarns in a twill design. Denim is a sturdy, cotton warp-faced textile in which the weft passes under two or more warp threads.
[0005] A well known problem with denim fabrics is that fabrics obtained from 100% cotton yarns may be quite stiff and rigid. To solve this problem, denim fabrics have been provided with elastic yarns, usually weft yarns, which reduce stiffness of the fabric and improve wearability. These fabrics are called "stretch woven fabrics" or "stretch fabrics". In these stretch fabrics, the elastic yarn provides the elasticity required for the fabric to stretch and to recover the stretched portion. Because the elastic yarn is part of the fabric, a usual requirement is that it does not compromise the aspect and the look of the fabric. To this purpose, the elastic yarns often include a core made of an elastomer and a cover for the core that is made of inelastic fibers, generally cotton fibers, so as to mimic the appearance of a standard, non-elastic, 100% cotton yarn. [0006] The reference to any prior art in this specification is not, and should not be taken as, an acknowledgement or any form of suggestion that the prior art forms part of the common general knowledge.
[0007] Generally, embodiments of the present invention relate to a textile and a garment comprising a dual weave of composite materials.

[0049] In order that the invention may be readily understood and put into practical effect, reference will now be made to embodiments of the present invention with reference to the accompanying drawings, wherein like reference numbers refer to identical elements. The drawings are provided by way of example only.
[0050] Figure 1 is a schematic diagram showing a simplified representation of the textile according to one embodiment of the invention.
[0051] Figure 2 is a photo of the textile according to one embodiment of the invention.
[0052] Figure 3 is a flowchart showing the steps according to one embodiment of a method according to the invention.
[0053] Figures 4 to 4E are drawings showing various embodiments of a garment according to the invention.
[0054] Skilled addressees will appreciate that elements in the drawings are illustrated for simplicity and clarity and have not necessarily been drawn to scale. For example, the relative dimensions of some elements in the drawings may be distorted to help improve understanding of embodiments of the present invention.
[0055] Embodiments of the present invention relate a textile and garments comprising a dual weave of composite materials. In a particular embodiment, this invention relates to a textile and garment comprising a dual weave of composite materials comprising cotton and ultra high molecular weight polyethylene (UHMWPE) and optionally one or more of a natural, synthetic or semi-synthetic fibre and elastane. In a more particular embodiment, the textile and garment comprises a warp face comprising a composite of cotton and UHMWPE and a weft comprising cotton and UHMWPE and optionally one or more of a natural, synthetic or semi-synthetic fibre and elastane.
[0056] As used herein, "textile" means any cloth, fabric, material or goods produced by for example, weaving, knitting, spreading, bonding, crocheting, knotting or felting. A textile may be produced by spinning raw fibres of wool, flax, cotton, hemp, or other natural or synthetic materials to produce long strands. Textile encompasses fabric and cloth as used in textile assembly trades thereby comprising any material made of interlacing fibres. The term "fabric" may be used in the textile trade to refer to a material that may be used in production of further goods such as, garments. The term "cloth" may be used synonymously with fabric or may be used to refer to a finished piece of fabric used for a specific purpose such as, a table cloth.
[0057] As used herein "yarn" means a long continuous length of interlocked fibres, suitable for use in the production of a textile. Yarn can be made from natural and/or synthetic fibers. A yarn may be a spun yarn or a filament yarn.
[0058] In this specification "weft" means the thread or yarn which is drawn through, inserted over-and-under, the lengthwise warp yarns to create cloth. A single thread or yarn of the weft, crossing the warp, may be called a pick. Another term for the weft is the fill or the filling yarn. Each individual warp thread in a fabric is called a warp end or end.
[0059] As used in this specification "warp" refers to a yarn or yarns placed lengthwise, crossed by and interlaced with the weft, which form the lengthwise threads in a woven fabric.
[0060] Warp is the lengthwise or longitudinal thread or yarn in a roll, while weft is the transverse thread.
[0061] In this specification "denim" refers to a cotton warp-faced textile in which the weft passes under two or more warp threads. Accordingly, textile 100 may be referred to as a denim.
[0062] Denim fabrics may be 5/1, 4/1, 3/1, 2/1, 1/1 or sateen weave fabrics. The number indicates how many connection points there are in the smallest repeat construction unit, or weaving scheme, of warp and weft yarns. That is, 1/1 means that at each connection the warp yarn is changing its position, namely from upside of the weft (face side of the fabric) to the downside of the weft yarn (back side of the fabric). Whereas 2/1 means "two up, one down", i.e. the weft is floating under two warps and then changing position from down to up; every three weft insertions the warp yarn position is changed once. Similarly, in 3/1 construction every fourth weft insertion there is one warp yarn position changing and, in 4/1 every fifth weft insertion the warp yarn changes its position once. When there is a high number of positions without changing, i.e. the longer the weft portion floating under the warp yarns, the looser and softer are the woven fabrics. As a result, 1/1 weave produces a textile stiffer than a 4/1 weave.
[0063] The weave may comprise a twill weave such as, a 3/1 right hand twill. The weave may comprise a warp-faced twill weave. The warp-faced twill weave may have a predominance of warp yarns on the face. The warp-faced twill weave may be stronger and/or more resistant to abrasion and piling. The strength and resistance may be compared to non warp-faced twill weaves; other weaves; or other textiles.
[0064] As used herein a "composite" or "composite material" is a material made from two or more constituent materials with significantly different physical or chemical properties that, when combined, produce a material with characteristics different from the individual components.
[0065] FIG. 1 is a schematic diagram showing a simplified representation of textile 100 according to one embodiment of the invention. Textile 100 comprises a warp face 1 10 and a weft 120.
[0066] The warp face 1 10 comprises a composite 1 18 of cotton 1 12, UHMWPE 1 14 and elastane 1 16. From the teaching herein, a skilled person is readily able to select a suitable cotton.
[0067] FIG. 2 shows a photograph of textile 100. In the embodiment shown in FIG. 2, warp face 1 10 comprises a 3/1 weave. In other embodiments, warp face 1 10 may comprise a 1/1 ; a 2/1 ; a 4/1 ; or a 5/1 weave.
[0068] In the embodiment shown in FIG. 2, weft 120 also comprises a composite 128 of cotton 122, UHMWPE 124 and elastane 126. The UHMWPE 124 may comprise spun UHMWPE.
[0069] In this embodiment, warp face 1 10 and weft 120 are milled from the same yarn.
[0070] In the embodiment shown in FIG. 2, composites 118, 128 comprise UHMWPE spun yarn 124 spun around an elastane fibre 126 (not shown).
[0071] Advantageously, by utilising elastane fibre 1 16, 126, warp face 1 10 and weft 120 comprises 20% lateral stretch.
