Abstract

The invention provides a water-repellent soft fabric. Organic silicon is attached on fibers of the water-repellent soft fabric. A method comprises the following steps: (2) preparing organic silicon emulsion: diluting dimethylsilane with water until the concentration is 3-10wt% for later user; (2) padding, namely immersing the fabric in the organic silicon emulsion in the step (1) and rolling through a roller; after the rolling is finished, scraping off the surplus organic silicon emulsion to obtain a fabric immersed with the organic silicon emulsion; and (3) drying the fabric which is immersed with the organic silicon emulsion in the step (2) and removing a large part of moisture, and then baking to cure organic silicon on the fibers of the fabric. The water-repellent soft fabric provided by the invention has a very good water-repellent effect, and the effect keeps unchanged after the water-repellent soft fabric is washed for a plurality of times.

Description

technical field [0001] The invention belongs to the field of textile material preparation, and in particular relates to a water-repellent soft fabric. Background technique [0002] For a long time, people have longed for clothes that can be used in rainy or sunny days. In rainy days, they can not only be waterproof, but also breathable and moisture-permeable, so that sweat can be drained out of the clothes in time. Can be worn comfortably. Therefore, waterproof, breathable and moisture-permeable fabrics are high-grade and special functional fabrics that have been developed and researched by the textile industry at home and abroad for decades, and are also upgraded products of conventional chemical fiber products with improved technical content and added value. [0003] The existing water-repellent soft fabrics can guarantee water-repellent performance, but their softness, skin-fitting behavior and hardness are not good, and the human body feels poor. It is necessary to deve...
