Problems solved by technology

The above two methods cover two methods of anti-felting treatment. The former introduces grafting groups on the wool surface, and the hand feeling of the fabric will be significantly affected by the existence of the coating, while the latter will inevitably lead to relaxation of the fiber structure.

Embodiment 1

[0028] The preparation method of the sandwich type anti-felting double-faced fabric of embodiment 1 comprises the steps:

[0029] S1: Scratch-coat chitosan acid solution on the A side of the inner wool fabric, the concentration of chitosan in the chitosan acid solution is 2%, dry naturally, wash and dry, and place the wool fabric in a low-temperature atmosphere for plasma deal with;

[0030] S2: Configure chitosan silica sol finishing solution. The main components of chitosan silica sol finishing solution are chitosan, silicon dioxide, organic polyacids, water, and the pH of chitosan silica sol finishing solution is 5. The percentage by weight of chitosan in the polysaccharide silica sol finishing solution is 0.5%, and the silicon content of the chitosan silica sol finishing solution is 2%;

[0031] S3: Soak the B side of the inner wool fabric with water spray, apply the chitosan silica sol finishing solution obtained in S2 on the wetted surface of the inner wool fabric and s...

Embodiment 2

[0038] Embodiment 2 is based on embodiment 1, difference is: the chitosan concentration in the chitosan acid solution is 5%; The weight percentage is 3%, and the silicon content of chitosan silica sol finishing liquid is 0.4%.

[0039] In the medium and low temperature plasma treatment process of S1, the non-polymerizable gas in the chamber of the plasma treatment device is argon, the applied voltage discharge frequency is 13.75MHz, the power is 200W, and the treatment time is 20s.

[0040] The preparation process of chitosan silica sol finishing solution in S2 is: dissolving chitosan in the chitosan mixed solution in the organic acid aqueous solution, adding water to the water glass to dilute, then adding the chitosan mixed solution to the water glass under stirring In the solution, adjust the pH value with an organic acid, and oscillate ultrasonically for 20 minutes; the organic acid is itaconic acid; the coating method in S3 is transfer coating.

Embodiment 3

[0042] Embodiment 3 is based on embodiment 2, difference is: the concentration of chitosan in the chitosan acid solution is 3.5%; The weight percent is 1.7%, and the silicon content of chitosan silica sol finishing liquid is 1.2%.

[0043] In the medium and low temperature plasma treatment process of S1, the non-polymerizable gas in the chamber of the plasma treatment device is ammonia gas, the applied voltage discharge frequency is 13.75MHz, the power is 100W, and the treatment time is 100s.

[0044] The preparation process of chitosan silica sol finishing solution in S2 is: dissolving chitosan in the chitosan mixed solution in the organic acid aqueous solution, adding water to the water glass to dilute, then adding the chitosan mixed solution to the water glass under stirring In the solution, adjust the pH value with an organic acid, and oscillate ultrasonically for 5 minutes; the organic acid is citric acid; the coating method in S3 is transfer coating.

Abstract

The invention discloses a preparation method of sandwich type anti-felting double-faced woolen cloth, comprising the steps of pretreating wool fabric, preparing chitosan silica solution finishing liquid, finishing, drying, bonding and the like. Chitosan solution is adopted to form a protection effect on inner layer wool fabric, so that after being subjected to plasma treatment in a low temperature atmosphere, the inner layer wool fabric is little in fiber surface loss, and influence on the original water repellency of wool fiber is little; the chitosan silica solution finishing liquid is used on one side surface of the inner layer wool fabric by finishing, components in the finishing liquid make a condensation reaction, and are crosslinked on the surface of the wool fabric to form a film with certain rigidity, so that the wool fabric has single-faced anti-felting performance; the inner layer wool fabric is compounded with light and thin outer layer fabric, and thus the double-faced woolen cloth excellent in anti-felting performance can be obtained.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to a method for preparing a sandwich type anti-felting double-faced 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...
