Problems solved by technology

[0002] Polyester is the fiber with the highest output of textile fibers and the most important raw material for textile products, accounting for more than 70% of the processing volume of textile fibers. Polyester fiber is a chemical synthetic fiber because of its high breaking strength, good light resistance, and crisp products. It is widely used in clothing and home textiles, mainly including coats, curtains, sofa fabrics, car interior accessories, etc. However, polyester is a superhydrophobic fiber with extremely poor hygroscopicity and rigidity, which limits its application in home textiles and certain clothing fields , such as summer cool clothing, underwear and bedding, etc.
[0003] The prior art has reported the research on silk fibroin-coated polyester. Polyester fiber or fabric coating is brittle, easy to break and fall off, and will affect the surface structure and even air permeability of the original fabric.
There are also reports in the literature that the weight gain rate of silk fibroin coating is low, the washing resistance is not ideal, or the moisture regain is still very low
so no market adoption

Embodiment 1

[0083] (1) Put the raw silkworm silk into 0.2% sodium carbonate aqueous solution at a bath ratio of 1:50 (g / mL), and treat it three times at 98-100°C for 30 minutes each time, and then deionized water The silk is fully cleaned, loosened, and dried in an oven to obtain degummed silkworm silk fiber.

[0084] (2) Weigh the degummed silkworm silk fibroin and dissolve it in an aqueous solution of calcium chloride-ethanol with a molar ratio of 1:2 at a bath ratio of 1:20 (g / mL), and dissolve it at 70°C for 5-7 hours to obtain silkworm silk Dissolved mixed solution.

[0085] (3) Weigh dextran G-50 and G-25 and put them into sufficient deionized water respectively, and put them in a boiling water bath for 1.5 hours. After cooling down at room temperature, drain them with glass rods and put them into an empty glass column to prepare the column bed volume. 2cm×60cm, after 2 hours of natural sedimentation, use a peristaltic pump to pressurize the column, and equilibrate the column with ...

Abstract

The invention provides a fibroin modification method for a polyester fabric. The fibroin modification method comprises the following steps: (1) performing desizing treatment on a polyester fabric to obtain a desized fabric; (2) processing the desized fabric with sodium hydroxide, and performing washing to obtain the fabric subjected to alkali treatment; and (3) dipping the fabric subjected to alkali treatment in a cross-linking agent solution, and performing a mixed reaction with silk fibroin with the molecular weight of 1,000-5,000 Da. According to the modification method, the fabric subjected to desizing treatment is processed with sodium hydroxide, and owing to alkali treatment, a polyester fiber molecular chain releases reactive sites; meanwhile, the fabric subjected to modification alkali treatment by silk fibroin with the defined molecular weight of 1,000-5,000 Da is adopted, and the silk fibroin with the specific small molecular weight is firmly introduced into the fiber surfaceof the polyester fabric by use of the covalent binding principle; the coolness, softness and anti-static property of the polyester fabric are improved; and meanwhile, the mechanical property is good,and the fibroin stability is excellent.
