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.
In addition, plasma treatment can also be used to partially peel off the scale layer, and chitosan can be used to protect the wool, but the crosslinking strength between chitosan and wool fiber is small, and the wool fiber treated with chitosan is Easy to peel off after plasma bombardment

Embodiment 1

[0029] The production method of the dirt-repelling and anti-felting wool fabric of embodiment 1 comprises the steps:

[0030] S1: Pre-oxidation treatment of wool fabric, soak wool fabric in hydrogen peroxide solution, heat up to 60°C, keep warm for 0.5h, the content of hydrogen peroxide in hydrogen peroxide solution is 7ml / L, then take out the fabric and dry;

[0031] S2: Foaming the chitosan acid solution on the surface of one side of the wool fabric, the concentration of chitosan in the chitosan acid solution is 0.5%, drying naturally, washing and drying, and placing the wool fabric in a low-temperature atmosphere for plasma treatment ;

[0032]S3: 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 t...

Abstract

The invention discloses a production method of a dirt repelling and felting resisting wool fabric. The method comprises the following steps: preprocessing a wool fabric, preparing a chitosan silica sol finishing liquid, finishing the obtained wool, and drying the finished wool. Hydrogen peroxide pretreatment and chitosan solution are adopted to protect the wool fabric, so damages to the surfaces of fibers obtained after plasma treatment in low temperature atmosphere are small; the chitosan silica sol finishing liquid is finished to the surface of one side of the wool fabric, and components in the finishing liquid undergo a condensation reaction, and are cross-linked on the surface of the wool fabric to form a film with certain rigidity, so the wool fabric has single side dirt repelling and felting resisting performances; the film formed on the surface of the wool fabric also has flexibility adapting to the fabric, the bonding area between the film and the fabric is large, the bonding strength is good, and the service life of the film bonded wool fabric is long; and chitosan has bacterium prevention and moisture absorption characteristics, so the finished wool fabric has the advantages of good handle, bacterium prevention, moisture absorption and breathability.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to a method for producing stain-repellent and anti-felting 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 st...
