Description
Technical field
The present invention relates to be used for cashmere textile finishing field, and in particular to a kind of cashmere based on aqueous high molecular resin
Textile foam method graphene finishing technique.
Background technique
In daily life, due to the physics of cashmere, chemistry and morphosis feature, its textile garment product is caused easily to rise
Hair pilling and generation accumulation of static electricity, therefore its easy care performance and snugness of fit are greatly affected, added value of product is big
It gives a discount.It in production practice, is using infusion process by film forming height to the primary solutions of cashmere textile these defects
Molecule resin treatment is at cashmere fiber surface (addition), or destroys cashmere fiber scale (subtraction) or addition and subtraction combination, or
Antistatic agent is adsorbed on cashmere fiber.These methods although achieving preferable effect, the damage of cashmere fiber compared with
Greatly, product feel is inevitably deteriorated；Meanwhile not only auxiliary dosage is big for these schemes, but also finishing effect is usually not significant enough,
Not enough persistently.To solve these problems, it studies the novel finishing technique of one kind or novel related auxiliaries is selected to become this field
Research and development focus.Currently, cashmere textile anti-fluffing and anti-pilling and the main technique methods of antistatic finish have:
1, the anti-pilling finishing technology of the cashmere textile based on aqueous high molecular resin (addition), this technical side
Case handles film forming macromolecule on cashmere fiber surface using dipping method, is covered by polymeric laminate to cashmere scale layer
Lid effect, reduces its direction friction effect, achievees the effect that anti-fluffing and anti-pilling.
Such as pacify grace come, Dang Huiru, practise intelligence China it is written " synthesis and application of novel cashmere knit goods anti-gigging-pilling agent "
(" cant science and technology " the 3rd phases of volume 42 in 2014) disclose by with homemade organosilicon modified polyether type anion aqueous polyurethane
Cashmere product is arranged, anti-fluffing and anti-pilling grade can be improved 1~2 grade, and the cashmere product feel after arrangement is more traditional
Finishing agent makes moderate progress.
Such as the big written " conjunction of polyester-type aqueous polyurethane cashmere anti-pilling finishing agent of Liu Haiyan, Xu Chengshu, Xing Jian
At and application " (" printing and dyeing assistant " the 4th phases of volume 32 in 2015) disclose by with homemade organosilicon modified polyester type anion
Aqueous polyurethane arranges cashmere product, and the pilling resistance of cashmere knit goods can be improved 1~2 grade, and fabric is soft
Soft, gas permeability and penetrability are good.
However, film forming macromolecule can not due to being all made of dipping method for pluronic polymer processing in fiber surface
Largely go deep into inside cashmere yarn with avoiding, cementation will be generated between fiber, yarn by drying in film forming procedure at it,
Cause auxiliary dosage larger and the feel of cashmere product is poor；Meanwhile this finishing technique scheme can not solve cashmere product
The problem of easily playing electrostatic.
2, anti-fluffing and anti-pilling and antistatic finish technology based on the cashmere textile for destroying cashmere fiber scale (subtraction),
This technical solution partly destroys the scale structure of cashmere fiber using biological enzyme, oxidant etc., its scale angle of release is polished,
It reduces its direction friction effect and improves its hygroscopicity, achieve the effect that anti-fluffing and anti-pilling and antistatic.
Such as Li Fazhou, written " the enzyme-linked legal anti-pilling finishing research of the reduction-" (" knitting of Chen Qianwei, Dai Fei et al.
Industry " the 9th phase in 2010) synergy by reducing agent, protease, hydrogen peroxide is disclosed, controllably destroy Cashmere fiber
The surface scale structure of dimension, 2~3 grades of anti-fluffing and anti-pilling grade for improving cashmere knit goods.
However, the feel of cashmere product deteriorates seriously after this technical solution arrangement, and complex technical process, operation are tired
Difficulty is likely to result in the incorrigible damage of fiber；In addition, although due to fiber surface scale damage layer and cause its hydrophilic
Property is improved, but this is still not enough to assign its excellent antistatic effect.
3, the antistatic finish technology based on physics, chemical method, this technical solution is by will be at antistatic chemicals
It manages in fiber surface, or its is surface roughening to improve its hygroscopicity, or by the technologies such as scribbled and weaving, realizes product
Antistatic effect.
As Zhang Meng, Fu Xiurong, Wang Li equal written " wool fabric novel antistatic method for sorting " (" cant science and technology " 2016
The 4th phase of year) application in wool antistatic finish such as metal ion, plasma, nano carbon black is described, pass through and improves sheep
The electric conductivity on wool fibre surface achievees the effect that antistatic.
Such as He Jie written " exploitation of Supercool polyester fiber/cotton/cashmere two-sided colored woven fabric " (" cant science and technology "
6th phase in 2017) the moisture absorbing and sweat releasing characteristic that makes full use of Supercool polyester fiber/silk/cotton blended yarn excellent, develop two-sided colored woven
Fabric.The fabric gives full play to the comprehensive advantage of 3 kinds of fibers, positive smooth, reverse side soft warming, moisture absorbing and sweat releasing, resist it is quiet
Electricity and be not easy pilling.
However, the usual technique of this technical solution and complicated perhaps specific aim of process is stronger or wind to cashmere product
Lattice feel is influenced too big and cannot be widely applied；Meanwhile the anti-fluffing and anti-pilling performance of cashmere product is also difficult to through this technology
Scheme obtains simultaneously with its antistatic effect.
