Embodiment 1

[0045] Take 50ml of sodium hydroxide solution with a mass fraction of 5%, put 2g of acrylic fiber into it, use a glass rod to completely impregnate the acrylic fiber, add it to a constant temperature water bath at 80°C and react for 8 minutes, after the hydrolysis reaction is completed, take out the fiber Repeated washing with deionized water until neutral. After drying the fiber, configure 50ml of cysteine ​​hydrochloride solution with a mass fraction of 1% in a beaker, put the fiber into the beaker to fully soak it, put it in a constant temperature water bath with a temperature of 90°C for 1 hour, and take out Repeatedly wash the fibers with deionized water until neutral, put the fibers in an oven to dry; configure 100ml of casein solution with a mass fraction of 2%, put in the fibers and stir until the fibers are fully dispersed and wet, then put them in a constant temperature water bath at 80°C After reacting for 10 minutes, the fibers were taken out and washed repeatedly ...

Abstract

The invention discloses an amino acid covalently coupled protein modified fiber material and a preparation method thereof. Firstly, acrylic fiber is hydrolyzed in a sodium hydroxide liquor, and fiberis taken out after the reaction ends, washed and dried to the constant weight; the fiber is put in an amino acid liquor for a reaction, taken out, washed and dried to constant weight; finally, the fiber obtained after the reaction with amino acid is put in a protein liquor for a reaction, and the fiber is taken out, washed and dried to the constant weight. The invention also discloses the acrylicamino acid covalently coupled protein modified fiber material. The invention innovatively provides a method for covalent bond surface grafting of hydrolyzed acrylic fiber and protein with hydrophilicamino acid as a coupling agent. The grafting efficiency is improved, the grafting rate is high, the grafting fastness is good, and all raw materials are substances essential to a human body and are harmless to organisms, green and environmentally friendly. The reaction is simple and convenient, the process is controllable, and large-scale production is facilitated. The acrylic fiber has excellentmechanical property.

Description

technical field [0001] The invention relates to a fiber material and a preparation method thereof, in particular to an amino acid covalently coupled protein modified fiber material and a preparation method thereof, belonging to the technical field of textile fiber modification. Background technique [0002] Many properties of polyacrylonitrile fiber are similar to wool, even better than wool, so it is called "synthetic wool" or "artificial wool". Acrylic fiber has excellent thermal performance, mechanical properties, and corrosion resistance, and its output is sufficient. It has a wide range of sources and a variety of varieties. It is a good source of choice for polymer fiber modified materials. However, due to the lack of free hydrophilic groups on the surface of polyacrylonitrile fibers, polyacrylonitrile fibers are hydrophobic fibers, which have poor hygroscopicity, are prone to static electricity, and are far less comfortable to wear than wool, which limits their use to...
