Problems solved by technology

However, due to the scale layer structure of wool fiber and the wet expansion of the fiber, the wool fabric is easy to feel and shrink. After a series of anti-felting treatments, the softness and hydrophilicity of the wool fabric will be greatly affected, and it is difficult to meet people's expectations. Soft and Comfortable Requirements for Wool Clothes

Abstract

The invention discloses an anti-ultraviolet softening agent for a wool fabric and a preparation method of the anti-ultraviolet softening agent. The anti-ultraviolet softening agent comprises the following steps: (1) preparing a titanium dioxide emulsion; (2) loading titanium dioxide; and (3) preparing a softening agent. A titanium dioxide loaded softening agent is adopted in the preparation method, and the surface of the fabric is covered with a layer of epoxy silicon oil modified waterborne polyamine film coupled with titanium dioxide, so that air gaps among parts of fibers are filled, the surface friction coefficient is reduced, the softening performance of the fabric is further improved, meanwhile, the wool fabric is enabled to have an anti-ultraviolet function, the heat conductivity ofthe wool fabric is improved, the damage of sun radiation to the wool fabric is reduced, and the service life of the wool fabric is prolonged.

Description

technical field [0001] The invention relates to the technical field, in particular to an anti-ultraviolet softener for wool fabric and a preparation method thereof. Background technique [0002] Wool fabric is very popular among consumers because of its unique appearance style and excellent thermal function. In recent years, people's pursuit of the thermal function of wool textiles has gradually weakened, and their interest in softness, smoothness and easy care has become more and more intense. However, due to the scale layer structure of wool fiber and the wet expansion of the fiber, the wool fabric is easy to feel and shrink. After a series of anti-felting treatments, the softness and hydrophilicity of the wool fabric will be greatly affected, and it is difficult to meet people's expectations. Wool garments are soft and comfortable. Since the softener can give the fabric a soft and comfortable feel, it can improve the quality and added value of the fabric, and has become...
