Abstract

The invention relates to a making method of a fabric, in particular to a making method of a single-face-super-hydrophobic and single-face-hydrophilic Janus-type fabric and belongs to the field of textile function arrangement. The method comprises the following steps that 1, the fabric is cleaned and then dried for use; 2, the single face of the fabric is protected, under the condition of constantoxygen pressure intensity, plasma glow discharge treatment is conducted on the single face of the fabric, after oxygen is switched off, under the condition of constant steam pressure intensity of a grafting monomer, plasma glow discharge treatment is conducted again, and the single-face-super-hydrophobic and single-face-hydrophilic Janus-type fabric is obtained. According to plasma glow dischargetreatment, a cold plasma treatment instrument is used for generating plasma glow, the plasma treatment power is within 30-120 W, and the time is within 1-10 min. According to the method, the technology is simple and easy to control, the method is suitable for single-face treatment of various cotton fabrics and acetate fiber non-woven fabrics, the functionality demand is met, and the method also has good wearing performance.

Description

technical field [0001] The invention relates to a preparation method of a fabric, in particular to a preparation method of a single-side super-hydrophobic single-side hydrophilic Janus fabric, belonging to the field of functional finishing of textiles. Background technique [0002] With the continuous improvement of people's living standards, while wearing clothes, textiles must also perform specific functions under many special conditions, while still maintaining their original comfort. This is not only related to the feel and style, but also related to The hydrophobic moisture permeability of the fabric has a lot to do with it. [0003] The Janus-type fabric with one side hydrophilic and one side hydrophobic has high added value, and has broad application prospects in separation filtration, medical hygiene, etc. This type of fabric is usually obtained by coating a hydrophobic finishing agent on one side, but the one-side superhydrophobic and one-side hydrophilic textiles ...
