Problems solved by technology

The copolymerization and blending method usually requires the addition of organic additives and high temperature reaction conditions in the process of production and processing, which increases production costs and energy consumption
The traditional post-finishing method is mainly the soaking method. Due to the disadvantages of poor washing resistance, poor air permeability, and direct contact between the inner surface coating and the human body, the fabrics produced by this method can no longer meet the market requirements.

Abstract

The invention discloses a preparation method of a single-side spraying type anti-microbial heating fabric, and the anti-microbial heating multifunctional fabric prepared by adopting the method. In thefabric prepared by the method, the particle size of contained nano silver ranges from 30 to 50nm, and the concentration of capsaicin ranges from 0.8 to 2 percent by weight. By utilizing a spraying method, a dopamine matrix can be uniformly dispersed on the surface of the fabric, so that the self-polymerization of dopamine can be effectively prevented; the nano silver is complexed with an imino group in a capsaicin molecular structure, so that the combination degree of an anti-microbial agent on the surface of the fabric is improved; hydroxyl at the end of a capsaicin molecular chain and the dopamine matrix form a hydrogen bond, a long chain structure thereof tightly wraps the dopamine / the nano silver, and the long chain structure, the dopamine and the nano silver form an organic whole. According to the prepared fabric, the feature of poor laundering durability of a traditional soaking method is greatly improved, and the fabric with a single-side coating has better air permeability compared with a fabric produced by a traditional process.

Description

technical field [0001] The invention belongs to the field of functional textiles, and in particular relates to a method for preparing a single-side spray-coated antibacterial and heating fabric. Background technique [0002] With the improvement of people's living standards, the requirements for textiles are not limited to keeping warm, but the demand for functional textiles is increasing day by day, and the market for heating fabrics is gradually expanding. At present, the preparation of heating fabric mainly includes copolymerization method, blending method and post-finishing method. The copolymerization and blending method usually requires the addition of organic additives and high temperature reaction conditions during the production process, which increases the production cost and energy consumption. The traditional post-finishing method is mainly the soaking method. Due to the disadvantages of poor washing resistance, poor air permeability, and direct contact between ...
