Abstract

The invention relates to a hydrophobic and hygroscopic fabric coating and a preparation method thereof. The preparation method comprises: after mixing a hydrophilic monomer, a hydrophobic monomer and a crosslinking agent, initiating polymerization and crosslinking on the surface of the fabric to obtain a hydrophobic and hygroscopic fabric coating , wherein the carbon chain length of the hydrophobic monomer is greater than that of the hydrophilic monomer, and the mass of the hydrophobic monomer accounts for 65% to 95% of the total mass of the hydrophilic monomer, hydrophobic monomer and crosslinking agent; the prepared hydrophobic The hygroscopic fabric coating is a copolymerized network structure mainly composed of hydrophilic segments (containing hydrophilic groups), hydrophobic segments (containing hydrophobic groups) and cross-linking agents. The hydrophobic segments play the role of repelling liquid droplets. The hydrophilic segment plays the role of absorbing gaseous water vapor. The preparation method of the invention is simple and easy, and the cost is low. The prepared fabric coating has good moisture absorption and hydrophobic properties, and the coating will not change the style of the fabric after modifying the base material, so the application prospect is good.

Description

technical field [0001] The invention belongs to the technical field of functional polymer materials, and relates to a hydrophobic moisture-absorbing fabric coating and a preparation method thereof. Background technique [0002] In recent years, the development of science and technology has driven the progress of all walks of life, and more comfortable, functional and intelligent fabrics in the textile field have become the focus of people's research. Hydrophobic and moisture-permeable fabrics, also known as breathable fabrics, mean that they cannot be wetted by water in a certain state, but the sweat emitted by the human body can diffuse or transfer to the outside through the fabric, without accumulating condensation between the body surface and the fabric. The moisture permeability is mainly related to the moisture absorption performance of the fabric material and the structure of the fabric material. Micro-fine synthetic filaments are used for high-density weaving and shr...
