Problems solved by technology

[0008] Liu Jinqiang and others reported that dichloro-s-triazine reactive dyes (X-type reactive dyes) were used as sericin fixatives (Journal of Zhejiang Institute of Silk Technology, 1994, Phase 1). Experiments showed that this type of dyes can be used for the fixation and finishing of silk sericin. , and can obtain a good dyeing effect, although the two-in-one glue-fixing and dyeing process cannot process the white glue-fixing silk fiber desired by adults, so that the color of the product cannot be controlled at will, and the application of the method is limited

Embodiment 1

[0040] The multi-dimensional cross-linking glue-fixing method of silk, according to the following steps:

[0041] (1) Put 8 times the mass of silk into water at 20°C, adjust the pH of the bath solution to 3.5 with formic acid, and soak for 1 hour.

[0042] (2) Dehydrate the fully soaked silk, put it into a bath of cyanuric chloride with a concentration of 5 times the mass of 20g / L, and add JFC0.2% (in terms of bath mass) and baking soda 0.2% (based on the mass of the bath liquid), soak for 1 hour, then adjust and stabilize the pH value of the bath liquid at 8.0 with 15% soda ash solution of mass concentration, raise the temperature of the bath liquid to 60°C and keep it for 4 hours.

[0043] (3) After de-drying the silk, stack it at 20°C for 2 hours, and then dry it naturally.

Embodiment 2

[0045] The multi-dimensional cross-linking glue-fixing method of silk, according to the following steps:

[0046] (1) Put 10 times the mass of silk into water at 30° C., adjust the pH of the bath solution to 4.5 with acetic acid, and soak for 1.5 hours.

[0047] (2) De-dry the completely soaked silk, and put 4 times the mass (the quality of the bath liquid is 4 times the silk mass) of p-(4,6-dichloro-1,3, 5-triazine-2-amino) sodium benzenesulfonate bath, and add JFC 0.15% (by bath mass) and baking soda 0.15% (by bath mass), soak for 2h, and then use mass The 20% concentration of soda ash solution adjusts and stabilizes the pH value of the bath at 9.5, and raises the temperature of the bath to 70° C. and maintains it for 2 hours.

[0048] (3) After de-drying (washing machine de-drying), the silk is stacked at 25°C for 6 hours, and then baked at 100°C.

Embodiment 3

[0050] The multi-dimensional cross-linking glue-fixing method of silk, according to the following steps:

[0051] (1) Put 9 times the mass of silk into water at 40°C, adjust the pH of the bath solution to 5.0 with formic acid, and soak for 2 hours.

[0052] (2) Dehydrate the completely soaked silk and put 6 times the mass of p-(4,6-dichloro-1,3,5-triazine-2-amino)sodium benzoate at a concentration of 60g / L In the bath liquid, add JFC0.25% (by bath liquid mass) and sodium bicarbonate 0.25% (by bath liquid mass), soak for 2h, then adjust the pH value of bath liquid with 10% soda ash solution of mass concentration And stabilized at 11, the bath was warmed to 65 ° C and maintained for 3h.

[0053] (3) After de-drying the silk, stack it at 30°C for 8 hours, and then bake it at 110°C.

Abstract

The invention discloses a multi-dimensional cross-linking glue fixing method for silk, which is characterized in that: the sericin fixing agent used is cyanuric chloride or cyanuric chloride derivatives or other products produced by Sichuan Tingjiang New Material Co., Ltd. Pickling chrome-free tanning agent TWS. The silk sericin fixation agent disclosed by the present invention has covalent bonds as the main chemical cross-linking bonds and assists various other chemical bonds in cross-linking. The multi-dimensional cross-linking structure of the formed space network is stable. In addition to glue and weight gain, it can also give silk a certain fluffy and elastic feel.

Description

technical field [0001] The invention relates to a silk glue-fixing method, in particular to a silk multi-dimensional cross-link glue-fixing method. Background technique [0002] Silk is an animal protein material, mainly composed of sericin and silk fibroin, of which silk fibroin accounts for about 3 / 4, and sericin accounts for about 1 / 4. Sericin and silk fibroin are composed of 18 kinds of amino acids and contain about 97% pure protein. Silk fiber is a kind of high-grade fabric raw material. The chemical and physical properties of the fiber material directly affect the comfort and feel of the fabric. Therefore, the functional treatment of silk fiber has always been the focus of the silk industry. field. The sericin layer in silk is prone to protein fiber swelling, rupture and hydrolysis in weak acid and weak alkali aqueous solution. Therefore, in traditional silk processing, people use this characteristic of sericin to remove the sericin layer and keep the silk layer. , ...
