Description
Affiliated technical field
The present invention relates to a kind of detection fabric and whether pass through polybasic carboxylic acid non-ironing (wrinkle resistant) arrangement, and noniron finish level method how.
Background technology
Because the formaldehyde problem of traditional wash and wear finisher in recent years, is studied poly carboxylic acid no-ironing finishing both at home and abroad.Numerous with the research of polybasic carboxylic acid as crease proofing agent in, mainly concentrate on BTCA (BTCA), citric acid (CA) and maleic acid (MA) and be the micromolecule polybasic carboxylic acid of representative and poly (PMA) etc.The crease recovery of COTTON FABRIC and handling property are good behind the poly carboxylic acid no-ironing finishing, strength retention still can, but cost is higher.Nonetheless, the non-ironing product of having relatively high expectations for free formaldehyde content is still in the majority with the polybasic carboxylic acid arrangement at present.Because the appearance character through fabric behind the poly carboxylic acid no-ironing finishing does not change substantially, people can't judge fast whether this fabric passes through its noniron finish, and the wrinkle resistant level after this fabric noniron finish of further qualitative understanding.Therefore, provide a kind of fabric that can detect whether to pass through poly carboxylic acid no-ironing finishing, and noniron finish level method how has become the technical problem that needs to be resolved hurrily.
Summary of the invention
Main task of the present invention is to provide a kind of method of can the fast detecting fabric whether passing through poly carboxylic acid no-ironing finishing.
Its technical solution is:
A kind of method of fast detecting poly carboxylic acid no-ironing finishing fabric takes alkaline developer and fabric sample to be checked to carry out chromogenic reaction, judges this fabric according to change color then and whether passes through poly carboxylic acid no-ironing finishing.
Above-mentioned alkaline developer is to select basic-dyeable fibre for use, and adjusting its pH value becomes a kind of akaline liquid.
Above-mentioned alkaline developer is to select cation dyes for use, and adjusting its pH value becomes a kind of akaline liquid.
Above-mentioned alkaline developer is to select for use direct dyes and basic-dyeable fibre to be mixed, and adjusting its pH value becomes a kind of akaline liquid.
Above-mentioned alkaline developer is to select for use direct dyes and cation dyes to be mixed, and adjusting its pH value becomes a kind of akaline liquid.
Above-mentioned alkaline developer, its preparation condition comprise that also the concentration of one or both dyestuffs elects 0.1%-3% as, and the concentration of sodium chloride is elected 0.4-4% as; Its finished product pH value is 8-9.
The above-mentioned chromogenic reaction time can be 1-10 minute.
Above-mentioned poly carboxylic acid no-ironing finishing fabric comprises at least by BTCA (BTCA), citric acid (CA) or maleic acid (MA) each kind fabric for the micromolecule polybasic carboxylic acid arrangement of representative, also comprises each kind fabric by poly (PMA) arrangement.
The method of above-mentioned fast detecting poly carboxylic acid no-ironing finishing fabric, it also comprises takes same alkaline developer that fabric blank sample and the non-ironing horizontal sample of a plurality of difference are tested one by one, sets up chromatogram scale one to one; After taking this an alkalescence developer and a fabric sample to be checked to carry out chromogenic reaction, relatively judge this fabric noniron finish level according to its color performance with the chromatogram scale then.
Above-mentioned alkaline developer and fabric sample to be checked carry out chromogenic reaction can be realized like this, with a small amount of alkaline developer drip drench in or be applied on the fabric sample to be checked, reaction is the flush away loose colour later, again row oven dry conversion zone and observe this field color performance.
The action principle and the effect of the inventive method are: when using poly carboxylic acid no-ironing finishing fabric, the esterification and crosslinking reaction takes place in polybasic carboxylic acid and cellulose macromolecule under acid condition, its esterification is carried out in two steps: the first step, polybasic carboxylic acid bakes down at high temperature, and two adjacent carboxyl dehydration become acid anhydride; In second step, acid anhydrides becomes ester with hydroxyl reaction on the big molecule of cellulose fibre; After crosslinked, have a large amount of carboxylic groups on the fabric, under alkali condition, carboxyl is positively charged, and basic-dyeable fibre or cation dyes can abovely be dyed painted.Utilize the inventive method, as the alkaline developer of taking to be mixed with direct dyes on a small quantity drips pouring or smears fabric sample to be checked etc., carry out chromogenic reaction, judge this fabric according to change color then and whether pass through poly carboxylic acid no-ironing finishing and noniron finish level thereof, as fabric coloring is the color of direct dyes, and then this fabric is without crossing poly carboxylic acid no-ironing finishing; Select the color or the advancing color of dyestuff as fabric coloring for use for other, then this fabric passes through poly carboxylic acid no-ironing finishing, and can judge that further this fabric is through the poly carboxylic acid no-ironing finishing level according to this painted depth.The present invention has detection fast, is convenient to characteristics such as operation, can bring great convenience to the producer and relevant consumer.
