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 relatively high High, not conducive to mass production
In the prior art, fabrics such as cotton and chemical fiber are mostly used as the surface layer of the air layer fabric, and the drape feeling is not strong

Embodiment 1

[0023] The anti-pilling wool face air layer fabric of embodiment 1, the air layer fabric is formed by sewing the wool fabric and the air layer auxiliary material, and the wool fabric is subjected to anti-pilling finishing, and the above-mentioned anti-pilling finishing includes the following 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: immerse the wool fabric in the first finishing solution, soak it at room temperature for 1 hour, take out the...

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: immerse the wool fabric in the first finishing solution for 3 hours at room temperature, take out the fabric, and heat it to 70°C under vacuum to dry it; S3: Pad the woolen 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 embodiment 3 and embodiment 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: Immerse 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 woolen 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 air layer fabric with a wool surface. The air layer fabric is formed by sewing or bonding and laminating a wool fabric and air layer auxiliary materials, wherein the wool fabric is subjected to anti-pilling treatment. The anti-pilling treatment comprises the following steps: preparing a first finishing liquid and a second finishing liquid; finishing the first finishing liquid; finishing the second finishing liquid; cleaning and drying the finishing liquids; and the like. 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 of an ethanediamine-modified polylactic acid in the second finishing liquid, so that the friction coefficients of the fiber surfaces are reduced, and the strength of the wool fibers can also be increased. The film-forming materials of the first finishing liquid and the second finishing liquid are good in biocompatibility; the anti-pilling effect of the fabric prepared by lamination of the wool fabric reaches the second level; the warming effect can be increased when the fabric is combined to the air layer fabric; and the fabric is high in vertical sense and relatively excellent in wearing comfort.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to an anti-pilling wool face air layer fabric. 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 curl and e...
