Embodiment 1

[0020] Prepare detergent 209 with a concentration of 2g / L, use Na 2 CO 3 Adjust the pH to 8, wash the rabbit hair fiber with water for 25 minutes at a bath ratio of 25 and a temperature of 30°C, and dry at 90°C. Then be 1.5% sodium dichloroisocyanurate (DCCA) treatment agent with respect to fiber mass fraction, and be the detergent 209 of 2g / L with concentration, adjust the pH of treatment solution with acetic acid to be about 4.5, at bath ratio Under the conditions of 30°C and 25°C, the rabbit hair fibers were modified for 30 minutes, rinsed with water, and dried in an oven at 90°C. Finally, use 2g / L NaHSO 3 , dechlorinated at a bath ratio of 25 and a temperature of 40°C for 15 minutes, then rinsed with a large amount of tap water, and dried at 80°C.

Embodiment 2

[0022] Prepare detergent 209 with a concentration of 3g / L, use Na 2 CO 3 Adjust the pH to 9, wash the rabbit hair fiber with water for 20 minutes at a bath ratio of 30 and a temperature of 20°C, and dry at 80°C. Then be 1.0% sodium dichloroisocyanurate (DCCA) treatment agent with respect to fiber mass fraction, and be the washing agent 209 of 3g / L with concentration, adjust the pH of treatment solution with acetic acid to be about 4.0, at bath ratio Under the conditions of 20°C and 30°C, the rabbit hair fibers were modified for 35 minutes, rinsed with water, and dried in an oven at 85°C. Finally, use 1g / L NaHSO 3 , dechlorinated at a bath ratio of 20 and a temperature of 50°C for 10 minutes, rinsed with a large amount of tap water, and dried at 90°C.

Embodiment 3

[0024] Prepare detergent 209 with a concentration of 1g / L, use Na 2 CO 3 Adjust the pH to 7.5, wash the rabbit hair fiber with water for 40 minutes at a bath ratio of 20 and a temperature of 25°C, and dry at 85°C. Then be 2.0% sodium dichloroisocyanurate (DCCA) treatment agent with respect to fiber mass fraction, and be the washing agent 209 of 1g / L with concentration, adjust the pH of treatment solution with acetic acid to be about 5.0, at bath ratio Under the conditions of 30°C and 28°C, the rabbit hair fibers were modified for 25 minutes, rinsed with water, and dried in an oven at 80°C. Finally, use 2g / L NaHSO 3 , dechlorinated at a bath ratio of 30 and a temperature of 45°C for 20 minutes, then rinsed with a large amount of tap water, and dried at 80°C.

[0025] The morphology of rabbit hair fibers after treatment with sodium dichloroisocyanurate (DCCA) is shown in the figure.

[0026] In the present invention, all medicaments are conventional chemical reagents.

Abstract

The invention discloses a pretreatment method for improving the spinning property of rabbit fur fibers, which comprises the following steps: low-temperature washing treatment of completely untreated rabbit fur fibers at first, modification through sodium dichloroisocyanate, dechlorination, water washing and drying. After pretreatment, the opening angle of the scales on the surfaces of the rabbit fur fibers can be increased, the frictional performance of the rabbit fur fibers can be improved, and the cohesive force is increased, thereby improving the spinning property of the rabbit fur fibers during the spinning process. Moreover, after pretreatment of the rabbit fur fibers, the original strength can be maintained to the largest extent, and the cohesive performance of the rabbit fur fiberscan also be enhanced, thereby solving the problem of a series of spinning yarn slippage during the spinning process, reducing the breakage rate of the spinning yarn in the spinning process, and improving the quality of the spinning yarn made of pure rabbit fur. The treatment technology has the advantages of low material consumption and low treatment temperature, and can save the energy and reducethe production cost.

Description

technical field [0001] The invention relates to a pretreatment method for improving the spinnability of rabbit hair fibers. Background technique [0002] Woolen fabrics are developing in the direction of diversification, lightness, functionality, and high grade. The traditional thick woolen woolen products for the purpose of keeping warm are gradually fading out of the market, and woolen textile products with novel styles, lightness, and softness have become the darlings of the market. However, due to The scales on the surface of rabbit down fiber are small and smooth, resulting in low cohesion and easy slippage during spinning, making it difficult to weave high-count pure rabbit down yarn. At present, there are roughly three solutions: (1) most of the rabbit hair (hair) is only spun into woolen yarn or blended with wool and other fibers, (2) the method of plasma etching the surface of the scales; (3) the use of acid and alkali treatment method; but the first method is diff...
