Embodiment 1

[0035] A kind of preparation method of multifunctional real silk fabric, concrete steps are as follows:

[0036] (1) Modified silk fabrics were obtained by impregnating silk fabrics with a dopamine aqueous solution, wherein the concentration of the dopamine aqueous solution was 2 g / L, the pH was 8.5, the dipping temperature was 45° C., and the dipping time was 24 hours. The pH value of the dopamine aqueous solution was obtained by adding three Hydroxymethylaminomethane solution and trishydroxymethylaminomethane hydrochloric acid solution are adjusted to obtain;

[0037] (2) Sodium sulfite solution is used to impregnate the modified silk fabric to obtain a reduced modified silk fabric, wherein the concentration of the sodium sulfite solution is 3g / L, the immersion temperature is 90°C, and the immersion time is 1h;

[0038] (3) Use ferric chloride solution to impregnate the reduced modified silk fabric to prepare multifunctional silk fabric, wherein the concentration of ferric c...

Abstract

The invention relates to a preparation method of multifunctional silk-containing fabric. Firstly, a dopamine aqueous solution is used to impregnate the silk-containing fabric; secondly, a reducing agent is used to impregnate the silk-containing fabric; and finally, a metallic compound solution is used to impregnate the fabric treated by the reducing agent to prepare the multifunctional silk-containing fabric. The LOI value of the finally obtained multifunctional silk- containing fabric is greater than or equal to 29.1%, the LOI value is greater than or equal to 26.3% after 15 times of washing,the UPF value is greater than or equal to 10.79, and the contact angle is greater than or equal to 128.5 degree. According to the preparation method of the multifunctional silk-containing fabric, thefinally obtained multifunctional silk-containing fabric has excellent flame retardant, washable, ultraviolet resistance and hydrophobic properties through the method that the silk-containing fabric is reduced by adding the reducing agent after the silk-containing fabric is modified by the dopamine. The raw materials of the preparation are environmentally friendly and can be easily obtained, and the method is low in requirements on equipment and has great popularization value.

Description

technical field [0001] The invention belongs to the field of functional finishing of textiles, and relates to a preparation method of multifunctional silk-containing fabrics. Background technique [0002] As a natural fiber, silk fabric has excellent comfort, soft luster and soft touch, and has moisture absorption, breathability and health care properties. It enjoys the reputation of "Fiber Queen" and is widely used in interior decoration such as curtains and lighting. supplies. Decorative materials are usually required to have flame-retardant, UV-resistant and water-repellent functions. Therefore, in order to meet the multi-functional needs in this field, it is also necessary to treat silk fabrics with flame-retardant, UV-resistant or hydrophobic treatments to increase their added value. [0003] There are many reports on the preparation technology of silk fabrics with only a single function, such as flame-retardant silk fabrics, UV-resistant silk fabrics, and water-repell...
