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]
The present invention relates to a kind of antibacterial deodourizing textile method, particularly a kind of nano antibacterial fabric preparation method belongs to the functions of textile fabrics process field.
[background technology]
Give the antibacterial textile function, can protect textiles itself to avoid the infringement of microorganism on the one hand, can protect the user to avoid the harmful microbe infringement on the other hand.
Textiles can be given and organic synthesis material, inorganic substances, natural materials can be divided into the material of antibacterial functions.From each side such as security, anti-microbial property, persistence relatively, the metal ion with silver, copper, zinc, cerium has very big excellent part.
There are three kinds having the method that antibiotic metal ion and fabric fibre combine.
First method is that the particle that is loaded with the antibiotic property metal ion is added in the filament, and the Dispersion of Particles that the method requires to add just can spin qualified fiber in very thin scope, certain technical difficulty is arranged, and can not be used for pure natural fiber.
Second method is earlier the antibiotic property metal ion to be loaded to phosphate, perhaps silicate, perhaps on other oxide particles, then such particle is attached on the fabric again, owing to be the particle of pre-preparation, the difficult dispersion, be difficult to enter the capillary structure place of fiber, in order to increase in conjunction with fastness, must use more binder, the result causes the puckery shortcoming such as hard of fabric feeling.
The third method is to adopt the method for immediate reaction, soak to execute by twice and have reactive solution, make metal ion, silver ion particularly, be reduced into nano-Ag particles on fabric, this method has well solved the shortcoming of the first two kind method, but has but brought the another one problem, be exactly that Nano Silver has been caught distinctive pale brown look to fabric, limited range of application.
[summary of the invention]
The objective of the invention is to, at above-mentioned the deficiencies in the prior art, a kind of preparing nanometer antibiosis fabric is provided, by the immediate reaction method, generate a kind of nano particle of white at the internal-response of fabric fibre, this particle itself has good binding ability with fiber, only needs binder seldom to increase the intensity of combination, and can improve the defective that Nano Silver causes look.
For achieving the above object, the present invention is by the following technical solutions:
A kind of preparing nanometer antibiosis fabric, with high molecular polymer as dispersant and auxiliary adhesive, with metal ion as antimicrobial factors, with organic matter as the deadman of metal ion on fiber, combine with coordinate bond with metal ion, reaction generates the antibiotic compound particle of nanoscale on fiber, makes fabric produce good antibacterial and deodouring function.This particle is not pure metal simple-substance, neither inorganic salts, and contained organo-functional group and fiber itself has affinity interaction.
The fabric of the present invention preparation, its anti-microbial property comes from the nano-complex particle that is deposited, and constantly discharges metal ion under the environment of certain humidity having, and kills the bacterium of contact.
Compared with the prior art, the advantage that has of the present invention is:
1. the present invention soaks the immediate reaction method of executing solution by secondary, internal-response at fabric fibre generates a kind of organic nanometer granule that contains antibacterial metal ions, this particle is different from the inorganic antibacterial particle of pre-preparation, back arrangement, it is organic composite granulated, be created on the fine structure place of fiber, itself has good binding ability with fiber, and only needs binder seldom increases the intensity of combination.And, be better than adopting inorganic antibacterial particle disposal fabric from manufacturing cost, energy consumption aspect.
2. can effectively improve the defective that Nano Silver causes look, because what the present invention formed on fabric is the organic nanometer granule of the metal ion of white, this organic granular commute causes the metal ion of look, as silver ion, the inhibition discoloration is arranged, not influence of color and luster to fabric has certain anti-tarnishing ability.
