Surface treatment method of fabric

Abstract

The surface treatment method of fabric includes forming coated liquid with different functions, such as hydrophobic function, bacteriostasis function or hydrophilic function with polymer possessing bridge radical; coating the coated liquid in different viscosity onto the surface of fabric by means of intaglio coating technology; and drying to form functional fabric with lasting single or composite functions, such as hydrophobic function, bacteriostasis function and hydrophilic function.

Description

technical field [0001] The present invention relates to a method for surface treatment of spun fiber products, and in particular to a method for manufacturing spun fiber products with single or composite functions. Background technique [0002] As people have different functional requirements for textile products, the function of textile products simply providing warmth can no longer meet the needs of consumers. The textile industry has continuously developed some functional textiles, such as textile products that can provide single or composite functions such as hydrophobicity, antibacterial or hydrophilic (moisture absorption). [0003] Textiles with hydrophobic function are coated with materials with hydrophobic function on the outer surface of the fabric, while textiles with hydrophilic (hygroscopic) function are coated with materials with hydrophilic (hygroscopic) function on the inner surface of the fabric. The textile with antibacterial function is to apply the mater...

Problems solved by technology

[0004] Coating these different materials on the same or different surfaces often leads to problems of uneven coating and insufficient firmness of the coating layer, resulting in poor water washing resistance

The prior art discloses a method to solve the problem that the coating layer is not strong enough and thus has poor water washing resistance. For example, Taiwan Patent Publication No. 429280 discloses that microwave plasma is used to activate the surface of the fiber product, and after free radicals are generated, it is combined with Monomers are grafted and polymerized to form functional groups to impart specific hydrophilic functions to fiber products; another example is Japanese Laid-Open Patent Publication No. 11-256476, which discloses the use of low-temperature plasma treatment to modify one side of knitted fabrics or non-woven fabrics In order to obtain products with different functionalities between the inside and the outside; for example, Japanese Laid-Open Patent Publication No. Hei 13-159074 discloses the use of atmospheric pressure plasma treatment, and the single-side modification of knitted fabrics or non-woven fabrics is carried out through 8 hours of continuous treatment. Obtain a product with internal and external functions

The use of energy irradiation method for single-sided modification has the following disadvantages: first, the method of modifying the surface of fiber products by using low-temperature plasma, and then endowing fiber products with specific functional functions, the reaction must be
