Embodiment 1

[0028] Goat hair (washed wool) 200g

[0029] Zinc chloride 100-700g

[0030] Thioglycolic acid 100-300g

[0031] Water 400-500g

[0032] Temperature 85-90°C

[0033] Time 0.5-4 hours

[0034] Add goat hair to the above-mentioned keratin solvent system in proportion, heat up to the specified temperature, and stir at a constant temperature until the goat hair is completely dissolved (generally within 4 hours), and a viscous, transparent, light brown liquid can be obtained. The molecular weight of keratin subunits is about 50,000-60,000 Daltons.

Embodiment 2

[0036] Coarse wool (washed wool) 200g

[0037] Zinc chloride 100-500g

[0038] Thioglycolic acid 100-300g

[0039] Water 400-500g

[0040] Temperature 85-95°C

[0041] Time 0.5-5 hours

[0042] Add coarse wool to the above-mentioned keratin solvent system in proportion, heat up to the specified temperature, and stir at a constant temperature until the wool is completely dissolved (usually within 5 hours), and a viscous, transparent, light brown liquid can be obtained. The molecular weight of keratin subunits is about 50,000-60,000 Daltons.

Embodiment 3

[0044] Goat hair (washed wool) 200g

[0045] Sodium thiocyanate 200-600g

[0046] Sodium sulfite 100-200g

[0047] Thioglycolic acid 100-300g

[0048] Water 400-500g

[0049] Temperature 90-100°C

[0050] Time 0.5-5.0 hours

[0051] Add goat hair to the above-mentioned keratin solvent system in proportion, heat up to the specified temperature, and stir for 0.5-5 hours at a constant temperature. After filtering, a viscous, transparent, light yellow liquid can be obtained. The molecular weight of keratin subunits is about 60,000-80,000 Daltons.

Abstract

A process for preparing the solution and solid of ceratin includes extracting ceratin from wool of goat and sheep, camel hair, feather, leather leftover, etc by reduction method, and preparing solution and solid by use of the reagent, such as inorganic salt, urea, or thiourea.

Description

technical field [0001] The invention belongs to a regenerative protein utilization technology in the application field of natural polymer materials. It dissolves various keratin raw materials and makes them into solutions or solids for further processing and application. Its solution has remarkable characteristics, and its solid phase powder products have white color (when using non-colored raw materials), subunit Characterized by high molecular weight. Background technique [0002] my country is a big producer of goat hair, especially stimulated by the high profits of the cashmere industry, the total amount of goat breeding in my country has increased sharply, and the total number of goats in stock is about 160 million. However, the cashmere output in the raw cashmere produced by each goat is very limited, the cashmere content is less than 40%, and more than 60% is goat hair fiber with very low use value; along with the production and processing of cashmere, natural A lar...
