Detailed description of the invention
The knitting jeans fabric of the present invention, selects indigo or the purified cotton yarns of black sulfide dye dyeing, special-shaped section spun polyester thread and elastomeric yarn braiding weft-knitted thing. In the present invention, the content of special-shaped section spun polyester thread is 20%��60%, it is preferable that 20%��45%. By the special-shaped section of spun polyester thread, the core sucting action of moisture is realized the rapid-drying properties of fabric. If the content of special-shaped section spun polyester thread is lower than 20%, fabric rapid-drying properties is not good. Rapid-drying properties residual moisture rate represents, residual moisture rate is more low, and rapid-drying properties is more good. The initial stage of the jean of the present invention and the residual moisture rate washing 10 times are less than 60%, it is preferred to less than 40%.
Designed by one-sided composition so that special-shaped section spun polyester thread mainly appears on fabric backing, and purified cotton yarns mainly appears on fabric face, reach the water-absorbing fast-drying effect of two-sided organizational structure. Use same specification yarn, more frivolous than two-sided tissue, elastic better, grammes per square metre is 250g/m2��350g/m2��
The section configuration of special-shaped section spun polyester thread used by the present invention is preferably cross, Y shape, the combination of multi-leaf-shaped or circular and non-circular section, wherein multi-leaf-shaped includes such as trilobal, quatrefoil etc.; Non-circular section is not particularly limited, it is possible to be cross equal section.
The number of the purified cotton yarns that indigo or black sulfide dye dyes is 16��40. Yarn count is too low, and fabric is too thick, and grammes per square metre is more than 350g/m2, snugness of fit is not good; Yarn count is too high, and fabric is too thin, and grammes per square metre is lower than 250g/m2, warmth retention property is not good.
In the jean of the present invention, elastomeric yarn used is spandex (PU), polybutylene terephthalate (PBT) yarn (PBT), polybutylene terephthalate (PBT)/polyethylene terephthalate parallel type elastomeric yarn (PBT/PET), PTT/polyethylene terephthalate parallel type elastomeric yarn (PPT/PET) or high viscosity polyethylene terephthalate/low viscosity polyethylene terephthalate parallel type elastomeric yarn (PET/PET). If during spandex, spandex feeds together with special-shaped section spun polyester thread and weaves; If during the elastomeric yarn of non-polyurethane, elastomeric yarn and special-shaped section spun polyester thread weave with 1:1 or 1:2 assortment. The elastic effect of the fabric considered, in the present invention, elastomeric yarn used is preferably spandex.
After being shaped by the grey cloth of braiding, sewing obtains ready-made clothes, then ready-made clothes is washed, owing to jean uses indigo or sulfuration reduced form dyestuff, by padding entrance fibrous inside, develop the color after carrying out reduction, little with the adhesion of fiber, under ENZYME WASH or friction condition, dyestuff drops, lighter, reaches imitative old characteristic.
General jean all easily fades, and the colorfastness to rubbing of cowboy is all poor. In the ready-made clothes stage, cotton color fixing agent need to be added, improve color fastness, the generation of the problem that fades when minimizing is worn. Although the common color fixing agent such as amino silicone oils smooth agent improving crock fastness can make web surface smooth, soft, reduce coefficient of friction, improve dry and wet crock fastness, but this type of smooth agent can bring certain water repellency to fabric, can affect the water absorption of fabric.
The present invention is initially charged cellulase during washing, is subsequently added into cross-linking reaction type olefines color fixing agent (high polymer) and fabric is processed. In drying course after fixation treatment; reactive crosslinked group on above-mentioned color fixing agent molecule is cross-linked into macromole voluntarily; one layer of protecting film with some strength is formed on face liber surface; thus coating dye on fiber; make dyestuff difficult drop-off, thus improving the dry and wet crock fastness of jean. The cross-linking type color fixing agent that Burroughs as triumphant in Zhangjiagang produces.
In the present invention, the concentration of color fixing agent used is preferably 20g/L��50g/L, and the drying temperature after fixation is 70 DEG C��100 DEG C. The concentration of color fixing agent is lower than 20g/L, and colour fixation is general; Higher than 50g/L, fabric feel is partially hard, and the film formed at fiber surface by color fixing agent is excessively fine and close, the water-absorbing fast-drying processing effect of road engineering after impact. When drying temperature after fixation is lower than 70 DEG C, cross-linking reaction is insufficient, and the film of formation is insecure, and it is general that color fastness improves effect; When drying temperature higher than 120 DEG C, the dimensional instability of the ready-made clothes that sewing obtains. By the dry fastness more than 3 grades of the fabric of fixation treatment, fastness to wet rubbing more than 2 grades.
After color fixing agent processes, the special-shaped section spun polyester thread of fabric reverse side is owing to defining thin film at fiber surface, and water absorption declines. The present invention is processed as water-absorbing fast-drying agent by selecting water dispersible polyester resin so that the water absorption that fixation treatment is expected below is significantly improved. Its main component is the block copolymer of polyester and polyethers, and wherein terylene is had stronger affinity by polyester segment, can produce cocrystallization with terylene, and polyether segment plays hydrophilic effect. Compared with conventional epoxy resin, silicone based water-absorbing resin, water-dispersion type polyester resin used by the present invention is better with the compatibility of the color fixing agent of fixation treatment, and the soaking effect of gained fabric is superior, and good endurance.
The concentration of water-dispersion type polyester resin is preferably 10g/L��30g/L, not only can improve the water-absorbing fast-drying of fabric, and can improve the pliability of fabric within the scope of this. When resin concentration is too low, the water absorption of fabric is improved inconspicuous, and feel is harder; And resin concentration too high time, color fastness and the water absorption of fabric have a declining tendency. Drying temperature after resin dipping is 70 DEG C��100 DEG C. When drying temperature lower than 70 DEG C, water-dispersion type polyester resin is not strong with the adhesion of polyster fibre, and water absorption is improved inconspicuous; When drying temperature higher than 100 DEG C, the size of the ready-made clothes that sewing obtains is unstable. The water absorption of fabric processed through water-dispersion type polyester resin can reach less than 5 seconds.
