Description
Technical field:
The present invention relates to a kind of silk fabric and preparation method.
Background technology:
Real silk fabric has a lot of good performances, as gas permeability and hygroscopicity, also has good drapability, soft gloss, special scrooping feel, and dress is soft comfortable, very popular.Along with continuing to bring out of new chemical fiber in recent years, the intrinsic defective of silk itself is more and more obvious, traditional silk product has been subjected to serious challenge, improve its wrinkle resistance and give its multiple specific function, the added value that improves silk is pressing for of establishing oneself in an unassailable position of silk manufacturing enterprise.Existing useless silk is not utilized effectively as the main byproduct of silk textile industry.
Summary of the invention:
The object of the present invention is to provide a kind of have silk fabric and preparation method crease-resistant, antibiotic, the uvioresistant complex function.
Technical solution of the present invention is:
A kind of anti-creasing anti-bacterial anti-violet composite function silk fabric is characterized in that: adopt following method to make:
(1) preparation fibroin Nano sol creasing anti-bacterial anti UV finishing agent:
A liquid preparation:, make the fibroin hydrolyzate with the useless silk of sodium hydroxide hydrolysis;
B liquid preparation: get butyl titanate, glacial acetic acid adds deionized water, be added in the hydrochloric acid solution after stirring, behind the peptization, cooling and aging, nano titanic oxide sol;
Composite: it is 3～5 that A liquid and B liquid are regulated pH respectively, mix again composite, fibroin Nano sol creasing anti-bacterial anti UV finishing agent that must be stable;
(2) arrangement: silk fabric is put into the agent of fibroin Nano sol creasing anti-bacterial anti UV finishing pad, get product after the drying.
A liquid and B liquid mix when composite in the step (1), and the weight ratio of A liquid and B liquid is 6: 4.
A kind of preparation method of anti-creasing anti-bacterial anti-violet composite function silk fabric is characterized in that: comprise the following steps:
(1) preparation fibroin Nano sol creasing anti-bacterial anti UV finishing agent:
A liquid preparation:, make the fibroin hydrolyzate with the useless silk of sodium hydroxide hydrolysis;
B liquid preparation: get butyl titanate, glacial acetic acid adds deionized water, be added in the hydrochloric acid solution after stirring, behind the peptization, cooling and aging, nano titanic oxide sol;
Composite: it is 3～5 that A liquid and B liquid are regulated pH respectively, mix again composite, fibroin Nano sol creasing anti-bacterial anti UV finishing agent that must be stable;
(2) arrangement: silk fabric is put into the agent of fibroin Nano sol creasing anti-bacterial anti UV finishing pad, get product after the drying.
In the step (1), when A liquid prepared, concentration sodium hydroxide was 1～5mol/L, and hydrolysis temperature is 70 ℃, and the waste silk consumption is 1～5g, and sodium hydroxide concentration is 50～250ml, and hydrolysis time is 1～2 hour; When B liquid prepares, get butyl titanate 3.5-35g, glacial acetic acid 0.6-6ml, add the 10-100ml deionized water with magnetic stirrer evenly after, it is added drop-wise in the hydrochloric acid solution of 40ml0.1mol/L concentration, simultaneously 20 ℃ of following constant temperature magnetic agitation after 30 minutes, be warming up to 40 ℃ of continuation stirrings and made it peptization in 40 minutes, take out the nature cooling and aging, get nano titanic oxide sol; When composite, the weight ratio of A liquid and B liquid is 6: 4 with A liquid and B liquid.
The concrete grammar of step (2) is: silk fabric is put into fibroin Nano sol creasing anti-bacterial anti UV finishing agent working solution pad, pick-up rate is 85%, and padding is two to soak two and roll; 90 ℃ of following preliminary dryings 2 minutes, under 120～160 ℃, bake again and handled 3～4 minutes then, wash then, dry product.
The useless silk fibroin finishing agent that hydrolysis is made that comes unstuck, have a certain amount of free active group, as hydroxyl, amino, carboxyl etc., can with the comparatively stable chemical bond of the intermolecular formation of silk fiber, or be deposited in the unformed area of fiber, thereby improve the wrinkle resistance of silk broadcloth.
The titanium dioxide that generates in the Nano sol has antibiotic preferably and uvioresistant function; Nano material can also be as the catalyst of fibroin anti-crease finishing with performances such as its surface area is big, the surface-activity center is many, high adsorption capacities.
Fibroin hydrolyzate and Nano sol under certain pH condition, are re-dubbed stable finishing agent by a certain percentage, have synergistic function, make the real silk fabric after the arrangement that anti-creasing anti-bacterial anti-violet composite function preferably be arranged.
The present invention is a raw material with useless silk, helps resource regeneration; Useless silk belongs to the natural green product, the finishing functions that the anti-creasing anti-bacterial anti-violet composite function silk fabric of exploitation meets the 21 century textiles should be that keynote is carried out the developing direction that arrangement is processed with safety with comfortable, cleaning, and catered to the consumption concept of people " environmental protection, health, fashion ", easy to process, cost is low.Product has creasing anti-bacterial ultraviolet-resistant composite function preferably after tested, and wherein wrinkle resistance improves 10～30%, uvioresistant UPF class 4 0～50
+, the inhibition zone of Escherichia coli and staphylococcus aureus is 1～10mm, soft, comfortable and easy to wear, satisfy and take requirement.
The invention will be further described below in conjunction with embodiment.
