Detailed description of the invention
In the present invention, warp thread adopts common polyamide fibre yarn, and weft yarn adopts the complex yarn of modification high convergency polyamide fibre and ordinary polyester, and the quality proportioning of polyamide fibre and terylene is 6:4 ~ 7:3, and complex yarn is 50D/24F ~ 75D/24F.
To be polyamide fibre 6 with polyamide fibre 66 modified copolymer cut into slices modification high convergency polyamide fibre that (UltramidC33) melt spinning is obtained, is developed by BASF AG.Knit structure and adopt existing fabric structure, but there is certain requirement, namely, can adopt and organize floating-point in the one side of fabric based on warp thread, organize the institutional framework of floating-point based on weft yarn at the another side of fabric, as twill, satin weave etc., also can adopt the institutional framework organizing floating-point suitable of warp thread and weft yarn, the tissue with such fabric construction has plain weave and most of dobby.
Fabric weft yarn is modification high convergency polyamide fibre and ordinary polyester two-component composite yarn line, thinks after test of many times, and be more suitable for jet and arrow shaft fabric manufacture equipment and weave, the fabric woven, after destarch-dyeing-Final finishing process, obtains velvet fabric.Concrete technology is as follows:
1, destarch: through weaving the blank fabric of acquisition, being placed in dye vat and carrying out destarch.Put the cloth woven into dye vat and carry out destarch process, destarch dressing liquid component is: concentration is caustic soda 15 ± 0.5g/L, degreaser 1.0 ± 0.5g/L, the chelated dispersants 1.0 ± 0.5g/L of 25-35%, and concentration of caustic soda is preferably 30%.Adopt following desizing: be that 1:10 ~ 15 add water by bath raio, water is warming up to 40 DEG C-50 DEG C, add destarch dressing liquid, circulate to water, the time is 5 ~ 10 minutes, is warming up to 105 ± 5 DEG C is then incubated with the speed of 1.5 ± 0.5 DEG C/min, temperature retention time is 80 ± 5min, be cooled to 70 ± 5 DEG C with the speed of 1.5 ± 0.5 DEG C/min again, then overflow is cooled to 45 ± 5 DEG C, is rejected to outside cylinder by water.
When destarch, the maximum temperature of destarch must be ensured, the maximum temperature of destarch is strict controlled within the scope of 105 ± 5 DEG C, because when the highest desizing temperature is lower than 100 DEG C, fully can not open as the modification high convergency polyamide fibre of weft yarn and the 16 tangerine lobe yarns of the two component complex yarn 50D/24F ~ 75D/24F of terylene 6:4 ~ 7:3, make fabric can not get velvet effect like this, when destarch maximum temperature is higher than 110 DEG C, yarn strength is badly damaged, and strength loss can reach more than 50%;
When destarch, another needs the strict project controlled to be amount of caustic soda, as amount of caustic soda is too large, not only make to be badly damaged as the modification high convergency polyamide fibre of weft yarn and the two component complex yarn brute force of terylene 6:4 ~ 7:3, and impact reduces its high convergency performance, if consumption is too little, its 16 tangerine lobe complex yarn fibrillation effect is incomplete, affects the velvet effect of fabric.
The following technique of preferred employing prepares destarch dressing liquid: first in the medicine-adding bin of 100L volume, add 1/3 water, then add whole chelated dispersants by formula rate, stir, whole degreaser is added again by formula rate, stir, then add water to 100L, stir and enter in dye vat in 3 minutes; Open the circulatory system between dye vat and medicine-adding bin, make liquid from dye vat internal liquid return to medicine-adding bin, then make liquid enter dye vat, circulating medical solution like this, adds caustic soda total amount in proportion gradually in medicine-adding bin, add-subtract time 5-15 minute, dosing is complete, closes closed loop system, obtains destarch dressing liquid.
2, dye, in dye vat, again add water, be warming up to 50 ± 5 DEG C, add in acetic acid and aqueous solution 20min, then draining; Again add water and be warming up to 40 ± 5 DEG C, dyeing routinely adds dyestuff and auxiliary agent, with the programming rate of 1.0 ± 0.5 DEG C/min, water is warming up to 80 ± 5 DEG C, again with 1.5 ± 0.5 DEG C/min be warming up to 100 ± 5 DEG C be then incubated 60 ~ 70min after, be cooled to 70 ± 5 DEG C with the speed of 1.5 ± 0.5 DEG C/min again, draining after overflow is cooled to 45 ± 5 DEG C, fabric go out cylinder, oven dry.
In this dyeing course, need programming rate be controlled, particularly control the heating rate being warmed up to 100 DEG C from 80 DEG C, can not be too low, can not be too high, the too low or too fast contractive effect that all can reduce modified nylon of programming rate, reduces the velvet of fabric.Also need in addition to control the highest dyeing temperature, control the highest dyeing temperature at 100 ± 5 DEG C and be incubated, shrink slowly when temperature is less than 95 DEG C of its modified nylon compositions, cause final velvet not strong, temperature is greater than 105 DEG C, the strength loss more than 50% of its yarn.
Final finishing: according to the final use of fabric, corresponding processing technology can be selected, but it is noted that the most high processing temperature of Final finishing required≤180 DEG C, in order to avoid super fine shrinkage nylon composition is brittle; In order to obtain outstanding velvet effect, HEAT SETTING fabric width is set as 103% ~ 105% of prepattern door width.HEAT SETTING fabric width can not be large, if greatly, the small looped pile that fabric is formed velvet can be evened up, and fabric face velvet effect is bad, if HEAT SETTING fabric width is little, easily produces folding line and make velvet uneven at fabric face.
In post-processing approach of the present invention, fabric blank is through destarch process, the 16 tangerine lobe yarns of two component complex yarn 50D/24F ~ 75D/24F are fully opened, complex yarn fibrillation becomes super fine, dyed process, its modified nylon composition efficient uniform is shunk, and the super fine composition of the terylene formed after terylene fibrillation forms evenly distributed microcosmic looped pile on complex yarn surface, brings strong velvet to fabric.
