Problems solved by technology

[0003] The woolen enterprises and woolen mills in mainland my country have to throw away a large amount of dirty wool, short wool and miscellaneous wool after screening every year, which not only pollutes the environment, but also brings great economic losses to the animal husbandry industry.
However, there is no report about directly mixing and dissolving wool and pulp for spinning and film drawing.

Embodiment 1

[0023] 1) Mix the cleaned and naturally dried wool raw material and dried pulp directly with the ionic liquid, heat and stir on a temperature-adjustable electric furnace, and heat and dissolve for 60 minutes to obtain an amber solution;

[0024] The weight ratio of the weight of the wool and pulp raw materials to the weight of the ionic liquid is 1:20;

[0025] The weight ratio of the wool and pulp is 1:1;

[0026] The ionic liquid is an ionic liquid of 1-butyl-3 methylimidazolium chloride salt composed of anions, cations and cations in a molten state at 100°C;

[0027] 2) Then, the solution obtained in step 1) is spun, and water is used as a coagulation bath to obtain biological protein wool fibers.

Embodiment 2

[0029] The wool raw material after cleaning is carried out pretreatment: namely, the wool raw material is 20% urea, 3% SDS and 3% NaHSO in weight percent concentration 3 In the mixed solution of 100 DEG C, carry out immersion treatment for 0.5h; the weight ratio of the pretreated material to liquid is 1:10;

[0030] Mix the pretreated wool raw material and dried wood pulp with ionic liquid, heat at 100°C (heat in a constant temperature oven, and stir from time to time) and dissolve for 12 hours to obtain an amber solution; the weight of the wool and wood pulp The weight ratio of the wool and the weight of the ionic liquid is 3:10; the weight ratio of the wool and the wood pulp is 1:2;

[0031] The ionic liquid is 1-butyl, 3-methylimidazolium bromide composed of anions, cations and cations in a molten state at 100°C;

[0032] Add 0.1% glycerin to the above dissolving solution, and then spin the glycerin-containing mixed solution, using methanol as a coagulation bath to obtain ...

Embodiment 3

[0034] The camel hair raw material after cleaning is carried out pretreatment: namely, the camel hair raw material is 10% urea, 6% SDS and 6% NaHSO at weight percent concentration 3 In the mixed solution of 70 DEG C, carry out immersion treatment for 1 hour; the weight ratio of the pretreated material and liquid is 1:20;

[0035] Mix the pretreated camel hair raw material and dried cotton pulp with ionic liquid, heat in an oil bath at 110°C, and stir from time to time, and dissolve for 10 hours to obtain an amber solution; the sum of the weight of the camel hair raw material and cotton pulp The weight ratio of the camel hair raw material to the weight of the cotton pulp is 1: 5;

[0036] The ionic liquid is a 1-allyl-3-methylimidazolium chloride salt composed of anions, cations and cations in a molten state at 100°C;

[0037] Add glycerin accounting for 1% of the volume of the solution to the solution, and then spin the glycerin-containing mixed solution, using acetonitrile a...

Abstract

The invention discloses a biological protein wool fiber preparing method, which comprises the following steps: blending animal fur and fiber to produce soluble liquid in the ion liquid with positive and negative ion of fusing condition at 100 deg.c and positive ion to form salt; solidifying in the water, carbinol, alcohol, cyanoethyl or (NH4)2SO4 solution; adding adjuvant in the soluble liquid; solidifying in the water, carbinol, alcohol, cyanoethyl or 30 percent (NH4)2SO4 solution; evolving biological protein fur fiber.

Description

technical field [0001] The invention relates to a novel textile fiber method, in particular to a method for preparing biological protein wool fibers by mixing and dissolving animal hair and cellulose raw materials. Background technique [0002] The export volume of my country's wool textile industry ranks first in the world. The demand for wool used in the wool textile industry is about 800,000 tons. my country's self-produced wool is about 400,000 tons, with a 50% gap. After my country's accession to the WTO, the export volume of wool textiles has continued to grow, and the supply of wool in the domestic market is quite tight. The price of foreign wool has risen, and the supply is also in short supply. This situation will not improve significantly in the short term. In such a situation, the development of the products of this project can timely supplement the insufficient supply in the wool market, and the variety of products can be adjusted according to the demand. The v...
