Method for darkening finishing of wool fabric

Abstract

The invention provides a method for darkening finishing of a wool fabric, and the method at least comprises the following steps: (1) preparation of fluoroalkyl modified amino silicone oil; (2) emulsifying of the fluoroalkyl modified amino silicone oil; (3) padding; (4) preliminary drying; and (5) baking. Compared with the prior art, the method for darkening finishing uses the fluoroalkyl modified amino silicone oil as a finishing agent, the apparent color depth (K / S) of the wool fabric after the finishing can be increased by more than 20%, and the hand feeling, the flexibility and the serviceability of the fabric may not be affected.

Description

technical field

[0001] The invention relates to a method for finishing fabrics, in particular to a method for deepening and finishing wool fabrics. Background technique

[0002] Fabric dyeing depth is restricted by fiber dyeing balance and dyeing fastness, and sometimes it is difficult to meet the requirements. For dark-colored products whose dyeing depth does not meet the requirements or the amount of dye is large, the darkening agent has good practical value. One of the deepening methods is to cover the surface of the fabric with a low refractive index film to change the degree of reflection and refraction of the fiber to light, so as to obtain a better apparent dark color effect. More film-forming substances are organic fluorine, Silicone and acrylate resins. Organic fluorine resin has a good dark color effect due to its low refractive index (below 1.40), but its price is high; silicone resin has good flexibility but poor darkening effect; acrylic resin has good dar...
