Abstract:
The present invention relates to a method for forming vintage effect washer by blowing up by air on one to another synthetic fiber filament yarns of a fabric, dyeing and drying the fabric with the filament yarns blown up as described in the above, getting the synthetic fiber partially back to the condition prior to the blowing-up of the synthetic fiber, thereby naturally producing a creased appearance.

Description:
BACKGROUND OF THE INVENTION 
     Field of the Invention 
       [0001]    The present invention relates to a method for coating a creased appearance on fabric. More particularly the present invention relates to a method for forming vintage effect washer by blowing up by air on one to another synthetic fiber filament yarns of a fabric, dyeing and drying the fabric with the filament yarns blown up as described in the above, getting the synthetic fiber partially back to the condition prior to the blowing-up of the synthetic fiber, thereby naturally producing a creased appearance, and the present invention also relates to the vintage effect washer manufactured according to the method described in the above. 
         [0002]    Recently, in both the East and the West, the vintage fashion is getting popular among youth. The vintage fashion means second-hand clothes such as trousers with the cloth-edge being worn out and the stitching having come undone, shirts pock-marked with holes, discolored clothes worn for long, etc., and/or it is defined as a trend or tendency showing that people enjoy wearing second hand clothes as such. Lately, clothes with numerous rumpled creases formed on such as old clothes are also included in the vintage fashion. 
         [0003]    However, different from a natural fiber, a synthetic fiber is crease-resistant, and the reality is that the clothes made of synthetic fiber can hardly meet the demand arising from the vintage fashion. 
       SUMMARY OF THE INVENTION 
       [0004]    Today the vintage fashion has been brought into fashion among some youths, the likes or dislikes of the vintage fashion being out of the question. Accordingly its demand has been steadily increased. In the meantime, the recent spread of the well-being trend has caused the demand for the natural fiber also to increase steadily. Nonetheless, the demand for the fiber is met mostly by the synthetic fiber, because of the high price and insufficient supply for the natural fiber. However, because the synthetic fiber is crease-resistant, it is very difficult to form creases on clothes made of synthetic fiber. Therefore, it is desirable to develop a method for forming creases on the clothes made of synthetic fiber. 
         [0005]    The present invention is intended to solve the technical problem described in the above and enable to form on synthetic fiber creases tantamount to creases on natural fiber first by blowing up by air on one to another synthetic fiber filament yarns of a fabric, dyeing and drying the fabric with the filament yarns blown up, forming creases naturally on the synthetic fiber, that is, clothing fabric, and using the fabric to make clothes.

       DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0008]    The present invention is described in detail as follows: 
         [0009]    The  FIG. 1  illustrates a flow chart showing a process for forming creases on synthetic fiber. 
         [0010]    The synthetic fiber used in the present invention is polyester. And several sizes are available for the thickness of a filament, but it is desirable to use 50, 65 and 75 denier fibers, which are used most in the clothing manufacture. 
         [0011]    The present invention is described in detail with reference to the drawing as follows: 
         [0012]    The first step is to prepare a sufficient length of fabric ( 100 ) to convolve the roll ( 110 ). Normally a shipment is made for the unit of 50 m. However, taking into consideration that the fabric should go through a series of works, such as the crease-forming device ( 200 ) through the crease-fixing device ( 300 ) and the dying machine ( 400 ), where dying requires a plurality of circulation, to the drying machine ( 500 ), it is necessary to convolve the roll ( 110 ) with a sufficient length (e.g. 1000 m) of fabric ( 100 ), two or more units of fabric being connected. Various ways of connecting fabric to fabric such as sewing are available. 
         [0013]    Subsequently, the fabric ( 100 ) convolved around the roll ( 110 ) is delivered to the crease-forming device ( 200 ). The interior temperature of the crease-forming device ( 200 ) ranges 70 to 90° C. and a plurality of the air nozzles ( 210 ) are installed inside the crease-forming device ( 200 ). A filament assembly of a synthetic fiber is composed of dozen filament yarns. And when air blows up hard on the fabric ( 100 ) delivered to the crease-forming device ( 200 ) for two to four hours, the spaces between the filaments yarns composing the filament widen, the filament yarns become twisted, and, as a result, a creased appearance is formed. The fabric ( 100 ) that has gone through the crease-forming device ( 200 ), being compared with the original fabric ( 100 ), becomes wider by 20 to 30%. 
         [0014]    Further, the crease-formed fabric ( 100 ) with the spaces between the filament yarns widened as described in the above is delivered to the crease-fixing device ( 300 ), and heated under 90 to 100° C. for three to five hours, then the creases formed on the fabric are fabricated, that is, the creases embody the fabric ( 100 ), thereby, the creases are fixed, and not dissolved in the subsequent processing. 
         [0015]    Further on, the fabric ( 100 ) with the creases formed as described in the above is delivered to the dying machine ( 400 ), and dyed for a color tone as desired. The dying machine ( 400 ) is of a kind that is used normally in the industry. And inside are installed a plurality of rolls ( 400 ) which are convolved by the fabric, and in the lower part is contained the dyeing liquid ( 420 ). The fabric ( 100 ) delivered to the dying machine ( 400 ) is dyed by going through a process for a number of times, in which the fabric ( 100 ) circulates between the rolls ( 410 ) in the dying machine ( 400 ) and gets under the dyeing liquid ( 420 ) under a high temperature of 130 to 140° C. for two to four hours. Although the fabric ( 100 ) goes through the dyeing process described above, the spaces between the filament yarns are maintained, and the embodied creases do not dissolve. 
         [0016]    Lastly, the fabric ( 100 ) dyed as described in the above is delivered to the drying machine ( 500 ), and dried under a high temperature of 185 to 195° C. for five to seven minutes. The fabric ( 100 ) being dried in such manner in the above, the widening between the filament yarns in the crease-forming process turns back closely to the original width, but the creases formed on the fabric ( 100 ) do not dissolve. Therefore, the width of the dried fabric ( 100 ) is 5 to 10% bigger than the original width. The fabric ( 100 ) with the creases formed in such a process described in the above is convolved around the roll ( 100 ) and shipped out. 
         [0017]    Accordingly, the method of the present invention for forming vintage effect washer (which means for forming creases on synthetic fiber, hereinafter called ‘vintage effect washer’) is accomplished through the following steps: the 1 st  step for convolving a sufficient length of the fabric ( 100 ) around the roll ( 110 ); the 2 nd  step for delivering the fabric convolved around the roll ( 110 ) in the above to the crease-forming device ( 200 ) and blowing up hard by air on the fabric for two to four hours to widen the spaces between the yarns composing the filament, in the meantime, the filament yarns become twisted, thereby forming creases; the 3 rd  step for delivering the crease-formed fabric ( 100 ) in the above to the crease-fixing device, heating the crease-formed fabric ( 100 ) under 90 to 100° C. to fabricate the creases, thereby fixing the creases; the 4 th  step for delivering the crease-fixed fabric ( 100 ) in the above to the dyeing machine ( 400 ), circulating the crease-fixed fabric ( 100 ) between the rolls ( 410 ) under a high temperature of 103 to 140° C. for two to four hours, thereby dyeing the crease-fixed fabric ( 100 ); and the 5 th  step for delivering the fabric dyed as described in the above to the drying machine ( 500 ), and drying the dyed fabric under a high temperature of 185 to 195° C. for five to seven minutes, thereby drying the dyed fabric ( 100 ). 
         [0018]    Although the fabric manufactured in such a way is a synthetic fiber, it is very soft and gives high grade feeling and warmth retentivity like a natural fiber. Besides, differently from a natural fiber, the creases formed on the synthetic fiber as such do not dissolve from laundry and hold the original appearance made when creases are formed.
