Abstract

The invention relates to a hydrophobic moisture-absorbing fabric coating and a preparation method thereof. The preparation method includes that after mixing of hydrophilic monomers, hydrophobic monomers and cross-linking agents, polymerization and cross linking are triggered on the fabric surface to obtain the hydrophobic moisture-absorbing fabric coating, wherein the carbon chain length of the hydrophobic monomers is larger than that of the hydrophilic monomers, and the mass of the hydrophobic monomers accounts for 65%-95% of the total mass of the hydrophilic monomers, the hydrophobic monomers and the cross-linking agents. The prepared hydrophobic moisture-absorbing fabric coating is in a copolymerized reticular structure mainly formed by hydrophilic chain segments (containing hydrophilicgroups), hydrophobic chain segments (containing hydrophobic groups) and the cross-linking agents, the hydrophobic chain segments play a role in liquid drop repelling, and the hydrophilic groups playa role in gaseous vapor absorption. The preparation method is simple, feasible and low in cost, the prepared fabric coating has great moisture absorbing and hydrophobic performances, the fabric styleis unchanged after base material modification with the coating, and a promising application prospect is achieved.

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...
