Embodiment 1

[0037] In a 10-liter reactor, add 0.70 kg of 80-mesh casein powder and 0.20 kg of gelatin powder into 14.5 kg of 63.5% zinc chloride aqueous solution in equal amounts for 20 times, and stir while adding. The temperature was kept below 15°C and stirred for 10 hours. After 1 hour the temperature was raised to 73°C. Add 1.20 kg of acrylonitrile containing 0.0088 kg of azobisisobutyronitrile in equal amounts ten times within 40 minutes, and keep stirring at this temperature range for 6 hours. The viscous slurry prepared in this way is removed unreacted acrylonitrile under a vacuum degree of 100 Pa, and a 400-mesh sieve is used as a filter medium to filter out impurities, and vacuum defoaming for subsequent use.

[0038] The falling ball viscosity of this slurry is 220 seconds * , The content of water coagulable solids is 9.70%, which is suitable for spinning.

[0039] * The time required for a steel ball with a diameter of 3mm (0.110±0.001g) to settle 254mm in a glass tube wit...

Embodiment 2

[0041] The spinning dope was formulated as described in Example 1. The slurry uses 63.5% zinc chloride aqueous solution as a solvent, contains 6.3% of modified protein, of which keratin protein accounts for 73.6%, and casein protein accounts for 26.4%. Acrylonitrile monomers are grafted and copolymerized to prepare spinning slurry. After the slurry is filtered and defoamed, it is wet-spun with a spinneret with 2000 holes and a micropore diameter of 0.08mm, solidified in a coagulation bath containing 22% zinc chloride aqueous solution at 10°C, washed with warm water at 40°C, and stretched 2.8 times , and then stretched 8 times in a boiling water bath. After oiling, the tow is relaxed and densified in hot air at 105°C, and then relaxed and shaped in steam for 5 minutes to make fibers. The fiber fineness is 1.75dtex, the tensile strength is 1.5cN / dtex, and the elongation at break is 25.1%. Can be spun and weaved.

Embodiment 3

[0043] The spinning slurry was prepared as described in Example 1, and the slurry contained 86.8% of keratin and 13.2% of gelatin among the modified proteins. With acrylonitrile graft copolymerization, the slurry is made into fibers by the spinning method described in Example 2. The fiber fineness is 1.65dtex, the tensile strength is 2.0cN / dtex, and the elongation at break is 22.5%.

Abstract

The invention discloses an animal protein fiber and preparing method. The animal protein fiber is a copolymer of animal protein and C-C double-bonded monomer, the molecular weight 10,000-300,000, the content of the animal protein accounts for 10-75% of the total animal protein fiber, and the animal protein is single keratin or the mixture of the keratin with casein or collagen. The preparing method includes synthesis of spinning seriflux, after-treatment of the spinning seriflux, wet-process spinning, fiber solidification and fiber spinning stretch oiling compacted forming treatment. The animal protein fiber is a low cost high quality fiber with the animal protein as resource. The animal protein fiber: fineness is 1.0-3dtex, tensile strength is 0.8-3.5CN/dtex, and breaking extension is 15-45%.

Description

technical field [0001] The invention relates to an animal protein fiber and a preparation method of the fiber. Background technique [0002] Animal protein is a valuable natural resource whose value has not been fully exploited due to historical reasons. At the same time, due to the out-of-control of human activities, resource waste and environmental degradation are caused. Waste resources to be developed include waste coarse poultry feathers, pig hair, yak hair from slaughterhouses, coarse goat dregs by-products from cashmere processing plants, and keratin contained in horn and hoof debris; dander from leather industry Collagen protein contained; casein protein contained in milk that does not meet food requirements. Therefore, processing animal protein into fibers that can be used to make textiles has become a subject of great concern to many scientists and technicians. However, the fibers that have been industrialized at present still have the defects of poor processabi...
