Problems solved by technology

However, due to the limitations of the nature of the rabbit hair fiber itself and the processing conditions, the problem of easy shedding of rabbit hair fabrics has not been effectively solved, and has greatly restricted the development of the rabbit hair textile industry.
The applicant's experimental research shows that after finishing the rabbit fur fabric with water-based polyurethane, although the shedding amount is significantly reduced, after a conventional washing, the hair shedding amount of the rabbit fur fabric is significantly increased, and the finishing effect basically disappears, that is, the finishing effect is The washing resistance of the rear rabbit fur fabric is very poor

[0037] The preparation method of the resin finishing solution is as follows: according to the mass percentage composition of the resin finishing solution, under the condition of mechanical stirring and emulsifier OP-10, first mix water-based polyurethane, water-based blocked group isocyanate and water-based acrylic resin with mixed with water to form a homogeneous mixed solution; then the pH value of the mixed solution was adjusted to 7-8 with the regulator sodium bicarbonate or sodium carbonate to obtain the resin finishing solution;

[0038] (2) The mass percent of the finishing solution for improving the hand feeling consists of:

[0039] Amino silicone oil softener 5-25%,

[0040] The balance is water, and the sum of each component is 100%;

Abstract

The invention discloses a hair slip prevention finishing agent and a finishing method for a rabbit hair fabric. The finishing agent comprises resin finishing liquor and hand feeling improvement finishing liquor. The resin finishing liquor consists of the following components in percentage by mass: 5.5 to 25 percent of waterborne polyurethane, 4 to 15 percent of watercraft acrylic resin, 0.5 to 1.5 percent of waterborne terminated isocyanate, 1.5 to 2.5 percent of emulsifier OP-10, 0.1 to 1.0 percent of regulator sodium bicarbonate or sodium carbonate, and the balance of water. The hand feeling improvement finishing liquor consists of the following components in percentage by mass: 5 to 25 percent of amino-modified silicone oil softener and the balance of water. In the finishing method, the finishing agent disclosed by the invention and a one-step finishing process (1) and a two-step finishing process (2) are adopted. The finishing agent disclosed by the invention is easy to prepare, has low cost, is convenient to use and has good hair slip prevention effect. The finishing method disclosed by the invention has simple process and is suitable for industrial implementation.

Description

technical field [0001] The invention relates to textile finishing technology, in particular to an anti-lint finishing agent and an anti-lint finishing method for rabbit fur fabrics using acrylic resin physically blended and modified water-based polyurethane. Background technique [0002] Rabbit hair is slender, smooth and shiny, and is a precious raw material for wool textiles. Rabbit fur is light in texture, smooth and fluffy, soft to the touch, and the color of rabbit fur is white, so it has great adaptability to dyeing and color matching. In addition, due to the well-developed air-filled medullary layer in the rabbit hair fiber, the rabbit hair not only has high hygroscopicity, but also has excellent thermal insulation performance. According to relevant literature (referring to [1] Xue Jiying. Special animal fiber product and processing [M]. Beijing: China Textile Press, 1998.) introduction, the heat retention rate of rabbit hair is 68.5%, and the heat retention rate of ...
