Abstract

The invention is a wool anti-felting finishing method, and its character: the preprocessing adopts chitosan water solution for soaking and adopts neutral proteinase and neutral fatty to make enzyme degradation treatment, thus making the felting ratio of the processed wool fabric less than 3%, and strong damage within 5% and raising balling resistance of wool fiber by 2-3 grades, and also the whiteness, able to completely meet the machine washing requirement. The invention simplifies the processing course and shortens the process flow and has a shorter cycle so as to strengthen the feasibility in industrialized operation and has no residual harmful matters and can not cause environmental pollution.

Description

technical field

[0001] The invention belongs to the improvement of an anti-felting finishing method for wool and wool fiber, in particular to the anti-felting finishing technology for wool and its textiles by using biological enzymes. Background technique

[0002] As we all know, wool fabrics will gradually experience felting and pilling when they are worn or washed, that is, the wool fibers lose their elasticity and curl, which makes the fabric shrink and affects the appearance and wearability of the fabric. Therefore, wool fabrics need to be chemically dry-cleaned, or lightly washed with extreme care, and cannot be "machine washed", which makes washing wool fabrics extremely inconvenient. The research on wool anti-felting has been going on for a long time, and a variety of anti-felting finishing technologies have been developed. In summary, there are two main categories: one is chemical method, and the other is the combination of chemical and biological technology. [000...
