Problems solved by technology

However, the above-mentioned anti-pilling additives are complex in composition and poor in biocompatibility, and the addition of high-viscosity montmorillonite clay will inevitably cause changes in wool color and affect its dyeing effect
There are also technical solutions that use keratin to finish wool fabrics. However, it is necessary to form a continuous film on the surface of wool fibers to achieve the purpose of reducing the friction coefficient of the fiber surface. Therefore, the protein content in the keratin finishing solution is relatively large, and the cost is low High, not conducive to mass production

Embodiment 1

[0023] The anti-pilling finishing method of the wool fabric of embodiment 1 may further comprise the steps:

[0024] S1: Configure the first finishing solution and the second finishing solution. The main components of the first finishing solution are keratin powder, organic acid and water. The weight percentage of keratin powder in the first finishing solution is 1%; The main components are ethylenediamine-modified polylactic acid, ethyl lactate and polycarbodiimide, the weight percentage of ethylenediamine-modified polylactic acid in the second finishing liquid is 0.2%, polycarbodiimide and ethylenediimide The weight ratio of amine-modified polylactic acid is 0.03:1;

[0025] S2: Soak the woolen fabric in the first finishing solution for 1 hour at room temperature, take out the fabric, and dry it by heating to 60°C under vacuum and reduced pressure;

[0026] S3: Pad the wool fabric once in the second finishing solution, take it out, and dry it at a temperature lower than 70°...

Embodiment 2

[0030] The difference between embodiment 2 and embodiment 1 is: the weight percent of keratin powder in the first finishing solution is 4%; the weight percent of ethylenediamine-modified polylactic acid in the second finishing solution is 2%, and the The weight ratio of amine to ethylenediamine-modified polylactic acid is 0.1:1; S2: soak the woolen fabric in the first finishing solution, soak it for 3 hours at room temperature, take out the fabric, and heat it to 70°C for drying under vacuum and reduced pressure; S3 : Pad the wool fabric twice in the second finishing solution, take it out, and dry it at a temperature lower than 70°C.

[0031] The weight percentage of the organic acid in the first finishing solution is 70%; the second finishing solution contains a plasticizer tributyl citrate, and the weight ratio of the plasticizer to ethylenediamine-modified polylactic acid is 0.01:1.

Embodiment 3

[0033] The difference between Example 3 and Example 1 is: the weight percent of keratin powder in the first finishing solution is 2.5%; the weight percent of ethylenediamine-modified polylactic acid in the second finishing solution is 1.1%, polycarbodiimide The weight ratio of amine to ethylenediamine-modified polylactic acid is 0.65:1; S2: soak the wool fabric in the first finishing solution for 2 hours at room temperature, take out the fabric, and heat it to 65°C under vacuum to dry it; S3 : Pad the wool fabric twice in the second finishing solution, take it out, and dry it at a temperature lower than 70°C.

[0034] The weight percentage of the organic acid in the first finishing solution is 80%; the second finishing solution contains a plasticizer, acetyl tributyl citrate, and the weight ratio of the plasticizer to ethylenediamine-modified polylactic acid is 0.02:1.

Abstract

The invention discloses an anti-pilling finishing method for a wool fabric. The anti-pilling finishing method comprises the following steps: preparing a first finishing liquid and a second finishing liquid; finishing the wool fabric with the first finishing liquid; finishing the wool fabric with the second finishing liquid; cleaning and drying the wool fabric; and the like. According to the anti-pilling finishing method, sulfydryl in a keratin molecule is combined with the sulfydryl on the wool surface; the bulges of scales are filled; and a finished protective film is formed on the surfaces of wool fibers through finishing by an ethanediamine-modified polylactic acid in the second finishing liquid, so that the smoothness of the wool surface is further increased, the friction coefficients of the fiber surfaces are reduced, the directional frictional effect of the wool is reduced, and the strength of the wool fibers can also be increased. The use amount of keratin for the anti-pilling finishing method is relatively small; in a manner of combining keratin finishing with polylactic acid finishing, the after-finishing cost is relatively low; and by adopting an organic acid solvent keratin, the drying operation for removing the solvent is relatively simple and feasible.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to an anti-pilling finishing method for wool fabrics. Background technique [0002] Wool has many excellent properties such as good elasticity, strong moisture absorption, good warmth retention, and soft luster. Wool fabrics are noble in style and superior in wearability. However, unfinished wool fabrics will shrink when they are continuously squeezed and rubbed during washing, which will cause changes in the appearance of the fabric, such as shrinkage of the fabric size, hairiness of the woolen surface, and chaotic texture. The continuous accumulation of the above changes will affect the appearance and quality of the fabric. The wearing performance limits the application fields of wool to a certain extent. The reason for the felting of wool fabrics is traditionally believed to be mainly caused by the directional friction effect caused by the wool scale layer structure and the cur...
