Abstract

The invention discloses an ecological anti-felting finishing method for wools. The pretreatment adopts hydrogen peroxide pretreatment; and by padding the wools into mixed finishing solution of fibroin finishing agent SP1 and chitosan with certain concentration, the anti-felting rate of the treated wool fabrics is less than 3 percent, the strength is increased by about 6 percent, the whiteness is changed little, the air permeability of the wool fabrics is superior to that of the primary fabrics, the elongation at break is reduced, the water absorption is increased, the handfeel is soft, the anti-pilling property of the wool fibers is improved by 2 to 3 levels, and the wool fabrics can fully meet the requirement of machine wash. The method comprehensively adopts the environment-friendly finishing agent to perform anti-felting finishing for the wools, has no residues of harmful substances, does not cause environment pollution, simplifies the treatment process, shortens the process flow, has shorter period, and improves the feasibility of industrialized operation.

Description

technical field

[0001] The invention relates to silk fibroin and chitosan anti-felting finishing technology for wool and its textiles, in particular to an ecological anti-felting finishing method for wool. Background technique

[0002] As a natural fiber, wool has many excellent properties that other fibers cannot match, such as: soft, elastic, natural and soft luster, good hygroscopicity, warmth retention, wrinkle resistance and stain resistance. It is suitable for making various clothes and is deeply loved by consumers. However, due to the scale structure on the surface of the wool fiber, the wool fabric has a tendency to feel and shrink under the conditions of humidity, heat and external force, and the area is reduced, which greatly affects the style and dimensional stability of the wool fabric. It is limited that wool fabric clothes cannot be washed with water conveniently, which increases the burden on consumers when taking them. With the change of international fashi...
