Abstract

The invention provides a method for obtaining directional water diversion fabric by using plasma treatment. The method comprises the following steps: preheating a fabric by using an inert gas plasma;secondly, carrying out surface activation treatment on the fabric by using an oxygen plasma; finally, carrying out plasma coating treatment on one surface of the fabric by using hexamethyl disiloxanestream. According to the method disclosed by the invention, the step of preheating the surface of the fabric by inert gas replaces a cleaning link at the early stage of the fabric, so that consumptionof water sources is favorably reduced and waste water is reduced; in addition, efficient combination of the coating is also facilitated, and further the cost of raw materials is reduced; active groups are formed on the surface of the fabric by oxygen plasma treatment, so that chemical combination of the hexamethyl disiloxane stream and the surface of the fabric in the coating process under plasmajet is facilitated, and fastness and washing resistance of the coating are improved. The method has the characteristics of simple process, energy conservation and water conservation; in addition, theobtained fabric has the advantages of good directional water diversion property, excellent breathability, high comfortableness, good durability and the like.

Description

technical field [0001] The invention relates to a method for obtaining directional water-conducting fabrics by using plasma treatment, and belongs to the technical field of textile functional finishing.
