Abstract

The invention relates to an aftertreatment method for a textile material. Particularly, the aftertreatment method comprises the step of continuously spraying nano-structural active water ions onto thesurface of the textile material so as to promote performance of the textile material; the textile material is a wool fabric and has performance of pilling resistance; the nano-structural active waterions are provided by a nano-structural active water ion generation device; the nano-structural active water ion generation device comprises a discharge system; the discharge system comprises electrodes; and each electrode is of a hollow cylindrical structure, a cross section of a hollow part is of a quatrefoil shape, the quatrefoil shape is an axisymmetric shape and consists of a cross shape andfour cone shapes, four cone shapes are positioned at four tail ends of the cross shape, the sharp ends of the cone shapes are connected with the cross shape, the round thick ends of the cone shapes are far away from the cross shape, and the center of the cross shape is positioned on a central axis of the electrode. The method disclosed by the invention effectively improves performance of the textile material and solves problems of expensive equipment, complex process, difficulty in control on the operation process, difficulty in large-area preparation and the like of aftertreatment on the textile material in the prior art.

Description

technical field [0001] The invention belongs to the technical field of post-processing of textile materials, and relates to a post-processing method of textile materials. Background technique [0002] In order to improve and enhance the quality of textiles and meet the market's requirements for comfort, functionality, fashion, safety and environmental protection of textile products, it is necessary to post-process textiles. However, at present, wet chemical treatment is mostly used for post-treatment. This method has the disadvantages of expensive equipment, complicated process, uneasy control of the operation process, difficulty in large-scale preparation, possible pollution caused by the use of chemical substances, and the need to consume a lot of resources to achieve the reaction conditions. In line with the sustainable development advocated by today's society. [0003] For example, wool knitted garments often produce pilling during daily wear and use, which not only ser...
