Problems solved by technology

[0005] The first method is to add particles loaded with antibacterial metal ions into the fiber filaments. This method requires the added particles to be dispersed in a very fine range to spin qualified fibers, which has certain technical difficulties and cannot be used for pure fiber. natural fiber
[0006] The second method is to load antibacterial metal ions on phosphate, silicate particles or their oxides, and then adhere these particles to the fabric. Because it is a pre-prepared particle, it is difficult to disperse and it is very difficult to It is difficult to enter the capillary structure of the fiber. In order to increase the bonding fastness, more adhesives must be used, resulting in disadvantages such as harsh fabric feel
[0007] The third method is to adopt the method of immediate reaction, and to make metal ions, especially silver ions, be reduced to nano-silver particles on the fabric by immersing a reactive solution twice. The shortcomings of the two methods, but it brings another problem, that is, the nano-silver dyes the fabric with a unique brownish-yellow color, which limits the scope of application.

Abstract

The invention relates to a method for preparing nanometer antibiosis fabric, which uses macromolecule polymer as disperse agent and auxiliary adhesive, uses metal ion as antibiosis factor, uses nitrogen organic as the anchor agent of metal ion on the fabric, to combine the metal ion with complex bond to form nanometer particles on the fiber, to generate better antibiosis function, while the product can kill staphylococcus, bacillus coli, etc, without harmful on human skin.

Description

【Technical field】 [0001] The invention relates to a method for preparing an antibacterial fabric, in particular to a method for preparing a nanometer antibacterial fabric, which belongs to the field of textile functional treatment. 【Background technique】 [0002] Endowing textiles with an antibacterial function can protect the textile itself from microorganism damage on the one hand, and protect users from harmful microorganisms on the other hand. [0003] The substances that can endow textiles with antibacterial function can be divided into organic synthetic substances, inorganic substances, and natural substances. In terms of safety, antibacterial performance, durability and other aspects, the metal ions of silver, copper, zinc and cerium have great advantages. [0004] There are three ways to combine antimicrobial metal ions with fabric fibers. [0005] The first method is to add particles loaded with antibacterial metal ions into the fiber filaments. This method requir...
