Abstract

The invention provides a preparation method for a crease-resistant shrinkproof silk woven fabric. The preparation method comprises the following steps: treating the fabric with a sodium hydroxide solution at first, immersing the fabric in a DMF solution of trimethylolpropane triacrylate; grafting dimethyl dihydroxy ethylene urea and otcamethylcyclotetrasiloxane onto the surface of the fabric; andthen treating the grafted fabric with an ethanol solution containing succinic anhydride-modified nanometer silica, sodium dichloroisocyanurate, modified fluoroalkyl polyether modified polysiloxanes, chitosan, silk fibroin and sodium alginate so as to obtain the crease-resistant shrinkproof silk woven fabric. Test results show that the wrinkle recovery angle of the treated fabric is as high as 298degrees, improved by one time or more compared with untreated fabrics, so the treated fabric has good wrinkle recovery performance; the fabric of the invention has breaking strength reduced to 857 N and break strength retention rate of 91.4%; thus, the fabric of the invention has greater advantages in crease resistance than the untreated fabric.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a preparation method of an anti-wrinkle and anti-shrink silk fabric. Background technique [0002] Silk fabrics are soft to the touch, have good moisture absorption and air permeability, and are comfortable to wear, but they are prone to wrinkling and shrinkage, which affects the wearability of silk fabrics. Therefore, people have been devoting themselves to improving the wrinkle resistance of silk fabrics for a long time. In the 1990s, as people paid more and more attention to wearing hygiene, the demand for developing a new generation of anti-wrinkle and anti-shrinkage fabrics is increasing. [0003] At present, a variety of anti-wrinkle and anti-shrinkage silk fabrics have been developed, but the anti-wrinkle performance of the fabric is poor, and the strength retention rate of the fabric after treatment is low, so the overall treatment effect on the fabric is po...
