Description
Invention field
The present invention relates to the preparation method and its usage of the antibacterial anti-fouling agent of a kind of cloth.The antibacterial anti-fouling agent of a kind of cloth of the present invention can be applied to the field that all cloth is used, such as clothes, bedding, sofa, towel, Curtains Fabrics, carpet, toy for children, automotive seat, hospital's sheet, mattress, women sanitary articles etc., can also be applied to food factory, pharmaceutical factory, daily use chemicals factory, animal reproduction field, especially in Military Clothing, bedding and clothing field, have significant application value.
Background and technology
In the environment of our life, exist microorganism everywhere, these microorganisms, our human body is shown to some is beneficial bacterium, some is harmful bacteria, in most cases, between these microorganisms, be mutual balance, thereby formed coordination and the balance of whole human habitat, Here it is, and our health and surface skin can the healthy main causes existing.But, once the microorganism species imbalance in environment and human body will make a small amount of harmful bacterium---pathogen acquisition advantage, it will give rise to diseases by the approach such as respiratory system, digestive system and skin of human body.In propagating these harmful microorganism cause of disease bacterium processes, the various textile fabrics inseparable with people's daily life, are exactly important " communication media ".Because this important " communication media " its hygroscopicity and specific area of textiles is large, more easily cause the breeding of microorganism.Because the sweat of human body skin, sebum and scurf have been created condition to bacterial reproduction, because bacterial reproduction can form the propagation of the mould of other kinds, also there are the fungies such as saccharomycete, these bacteriums are accompanied by temperature, moisture, oxygen and the nutrition that human body skin gives after transferring to textiles, reproduction speed is very fast, substantially every 10min bacterial number doubles, thereby produces unpleasant foul smell, and these moulds and foul smell are to cause skin disease and infectious disease main cause.Common people, generally can think various textile fabrics, after washing powder washing, above harmful microorganism cause of disease bacterium can be removed thereupon, this is very large understanding mistaken ideas really.There is evidence, on textiles, inoculate after the bacterial strain of some, adopt the method for operating of generally washing clothes, add with the hot wash of 80 ℃ after 10 minutes, on the textiles of every 0.1 gram weight, also have the existence of 63 strain microorganism bacteriums, even visible, adopt high-temperature water washing, all the microbial bacterial on textiles all can not be removed, the washing of general family can not adopt hot water still more, just adopts normal-temperature water.So the microbial bacterial on textiles can not adopt conventional washing methods to remove.
If give the function with kill harmful microorganism cause of disease bacterium by various textile fabrics (such as clothes, bedding, sofa, towel, Curtains Fabrics, carpet, toy for children, automotive seat, hospital's sheet, mattress, women sanitary articles etc.), so not only can block the route of transmission of harmful bacteria, can also eliminate due to harmful microbe breeding and decompose the foul smell producing.
The antibacterial anti-fouling agent kind of existing cloth, feature and the mechanism of action thereof:
According to related documents and application practice, on market, do not promote the use of the antibacterial anti-fouling agent product of similar cloth of the present invention, literature search is also the post-finishing agent of relevant anti-bacterial fibre manufacture or anti-bacterial fibre, there is no the report of the antibacterial and anti-pollution function of textiles being integrated mutually with the antibacterial anti-fouling agent of this patent cloth.The report of the post-finishing agent of relevant anti-bacterial fibre manufacture or anti-bacterial fibre, such as Chinese patent ZL00125721.8 and Chinese patent ZL00125768.4, simultaneously similarly also have with it and to report in known publication number CN1569923A, this patent application has been carried out partly describing to current published technology, in this series of patents method, polyamine and guanidine salt polymer have been introduced respectively in polyolefinic antibacterial and polyamine and the antibacterial applications of guanidine salt polymer in polyester, polyamide material.The method is to add antibacterial functions group in macromolecule carrier resin blend with it, through double screw extruder melt extrude, pelletizing.Use again this master batch to measure, mix with PET resin (or other resins), so that antibacterial matrices fully mixes with polymer, form uniform compound (or grafting, molecule assembling etc.), after spinning pump metering, enter filament spinning component, by spinnerets spinning, through cooling, oil, reel, form antibacterial spun filament, after spun filament drawn, can prepare the polyster fibre (or other fibers) of anti-microbial property.The antibacterial functions group that this method is produced thinks to be integral with chemical bond and matrix resin molecule strong bonded in theory, thereby can stand the repeatedly washing of washing agent.
But, while carrying out modification with this copolymer, in fact still can not avoid the durability of its anti-microbial property not to be subject to the impact of carrying out washing treatment completely.This is because through fierce processing procedure, it disperses the interface state of antimicrobial particle and fibrous matrix to change, and hydrolysis, moves antibacterial components, dispersed particle is returned to " sheath-core type " state again by original " anti-sheath-core type " structure, thereby anti-microbial property is reduced.What is more important, if the resulting antibacterial fabric of the method is in use polluted, its anti-microbial property can be subject to very large obstruction, because pollutant has covered the performance of its antibacterial functions.
Record in another known publication number CN102505467A, also current published technology is compared to detailed description, but known publication number CN102505467A and known publication number CN1569923A have certain relevance in function, and the weak point same with recording of known publication number CN1569923A.Known publication number CN102505467A is because technical formula design comparison is single; textile surface is not carried out to necessary soiling protective formula Design; therefore; if the resulting antibacterial fabric of the method is in use polluted; its anti-microbial property can be subject to very large obstruction equally, is also because pollutant has covered the performance of its antibacterial functions.
In above all publication subject schemes, all do not carry out the design of soiling protective formula, this is major obstacle common in their technology.In fact, this technical obstacle only, will be related to the anti-microbial property of target product, to such an extent as to above-mentioned all publications is can stood larger limitation in practical application area.
