Problems solved by technology

However, the sericin on the surface of silk fibers or the residual glue after industrial treatment is easy to denature and harden silk fibers in industrial processes such as frequent moisture absorption and dehumidification, heating, or natural use, resulting in rough silk fiber materials. short service life

Embodiment 1

[0018] The silk protein fiber treatment process is completed according to the following steps

[0019] (1), wetting process: in the refining pool, prepare 100 kilograms of aqueous solution with a pH value of 1 with sulfuric acid, weigh 1000 grams of silk and put it into the sulfuric acid aqueous solution to soak for 0.5 hour, and dehydrate the treated silk after soaking is completed.

[0020] (2), grafting treatment process: in another refining pool, add the emulsifying liquid that adds O-25 fully emulsified dodecylaldehyde with 100kg water and the emulsifier that accounts for 2% of dodecylaldehyde quality, The mass concentration of dodecyl aldehyde is 1%, and the silk fiber of processing gained in the step (1) is soaked in the emulsified liquid prepared, and while stirring, controls reaction temperature at 0 ℃, reacts 5 hours, then with small Adjust the pH value of the system at 10 with soda, continue soaking for 8 hours, wash after the reaction, and dry at 100°C to obtain th...

Embodiment 2

[0022] The silk protein fiber treatment process is completed according to the following steps

[0023] (1), wetting process: in the refining pool, prepare 100 kg of aqueous solution with a pH value of 4.5 with formic acid, weigh 1000 grams of silk and put it into the formic acid aqueous solution for 5 hours soaking, and dehydrate the treated silk after soaking.

[0024] (2), surface treatment process, in another refining pool, add the emulsification of the pentadecyl sulfonyl chloride fully emulsified with 100kg water and the sodium dodecylalanine that accounts for 1.5% of pentadecyl sulfonyl chloride quality Liquid, the mass concentration of pentadecyl sulfonyl chloride is 3%, the silk fiber of processing gained in the step (1) is soaked in the emulsified liquid prepared, while stirring, control reaction temperature at 25 ℃, react 10 hours, Then use potassium bicarbonate to adjust the pH value of the system to 11, continue soaking for 4 hours, wash after the reaction, and dry...

Embodiment 3

[0026] The silk protein fiber treatment process is completed according to the following steps

[0027] (1), wetting process: in the refining pool, prepare 100 kilograms of aqueous solution with a pH value of 2.5 with hydrochloric acid, weigh 1000 grams of silk and put it into sulfuric acid aqueous solution to soak for 2 hours, and dehydrate the treated silk after soaking;

[0028] (2), surface treatment process: in another refining pool, add the emulsion of cocoyl chloride prepared with 100kg water and account for 1% cetyl trimethyl ammonium chloride quality of cocoyl chloride, cocoyl chloride The mass concentration of the method is 0.5%. The silk fiber processed in the step (1) is soaked in the prepared emulsion, while stirring, the reaction temperature is controlled at 40° C., reacted for 2 hours, and then adjusts the temperature of the system with potassium hydroxide. When the pH value is 12, continue soaking for 5 hours, wash after the reaction, and dry at 80°C to obtain t...

Abstract

The invention discloses a treatment process and application of fibroin fibers. The process comprises the step of treating fibroin fibers by adopting a grafting modifier which has a structural formulaof R1X, wherein R1 is saturated or unsaturated alkyl chain of C8-C18, and X is a functional group which can performing a grafting reaction with fibroin; the X is epoxy group or sulfonyl chloride or aldehyde group or acyl chloride group; or the grafting modifier is chloro-silicane containing saturated or unsaturated alkyl chain of C8-C18. According to the treatment process, the treated silk fiber material has the capability of removing skin stains, has functions of softness, skin friendliness and the like, cannot be influenced along with the number of washing times, cannot influence the environment and human bodies; a silk product is not yellow or hard after repeated washing and air-drying, the biological activity of the silk fiber material is kept, the performance of the silk fiber material is improved, and the application range and field of the silk fiber material are expanded.

Description

technical field [0001] The invention relates to a treatment process and application of silk protein fibers, belonging to the technical field of textile materials. Background technique [0002] With the improvement of living standards, people are increasingly pursuing natural material products, such as silk, which is a continuous long fiber that is solidified by secreting silk liquid when cooked silkworms make cocoons, also known as "natural silk". Silk fiber is a protein fiber, and sericin and silk fibroin are its main components, of which silk fibroin accounts for about 70-80%, and sericin accounts for about 20-30%. Silk and human body's cutin and collagen are both proteins, and their structures are very similar. Therefore, they have excellent human biocompatibility. Silk fiber material has become the first choice because of its excellent biocompatibility. However, the sericin on the surface of silk fibers or the residual glue after industrial treatment is easy to denatur...
