The method of testing of the resistance to soaked colour fastness of textile
Technical field
The impact of the conventional home washings that the present invention relates to measure textile on its color, specifically refers to the method for testing of the resistance to soaked colour fastness of a kind of textile.
Background technology
Colour fastness particularly conventional home washings is resistance to soaked colour fastness on the impact of textile color, is an important indicator evaluating quality of textile products quality.At present, also there is not dependence test standard in country, cause each manufacturing enterprise not have testing standard to comply with, so that adopt separately different method of testings to carry out the mensuration of resistance to soaked colour fastness, method of testing is of all kinds, quite chaotic, be difficult to really reach test purpose, cause being difficult to differentiate from existing resistance to soaked colour fastness index the quality of textile.
Summary of the invention
The present invention is in order to solve the existing deficiency of the resistance to soaked colour fastness method of testing of existing textile, provide a kind of simple to operate, measure the method for testing of the resistance to soaked colour fastness of textile accurately.
The present invention is achieved through the following technical solutions:
The method of testing of the resistance to soaked colour fastness of textile, it comprises the following steps:
A) get the raw materials ready: the fabric sample to be measured that cutting one slip gauge is whole; The STANDARD ADJACENT FABRIC that sprinkles processing is dyed in 1~2 of cutting with fabric sample same size to be measured and through bleaching; The appropriate reagent of allotment concentration 10g/L adds appropriate phosphate-less detergent to make required reagent in not higher than the warm water of 60 ℃;
B) a neat stacked above-mentioned STANDARD ADJACENT FABRIC on a surface of fabric sample to be measured at least, and by four jiaos of bookbindings or stitching, fabric sample to be measured and STANDARD ADJACENT FABRIC are fixedly fit together, STANDARD ADJACENT FABRIC is fully contacted with fabric sample to be measured, make composite sample;
C) above-mentioned reagent water temperature is adjusted to proper temperature, more above-mentioned composite sample is put into reagent and stirred, composite sample is immersed in reagent completely, standing test 25~35min;
D) take out the composite sample in reagent and clean up, then STANDARD ADJACENT FABRIC and fabric sample to be measured are taken apart;
E) STANDARD ADJACENT FABRIC after above-mentioned fractionation, fabric sample to be measured are dried respectively, bake out temperature is not higher than 80 ℃;
F) adopt variable color standard scale, staining standard scale respectively with dry after STANDARD ADJACENT FABRIC, fabric sample to be measured grade and compare;
G) by grading, compare data, draw the resistance to soaked colour fastness of fabric sample to be measured;
H) complete documentation test process, and respectively the STANDARD ADJACENT FABRIC after comparison, fabric sample trimmed to be measured are pasted to sample and filed.
Further, above-mentioned fabric to be measured is polyamide fibre kind fabric; Above-mentioned steps only needs STANDARD ADJACENT FABRIC of cutting in a), and adopts overflow type dyeing polyamide fibre kind fabric to select TSL228
tfabric, as STANDARD ADJACENT FABRIC, adopts flat cylinder dye gigging form dyeing polyamide fibre kind fabric to select 230
tplain weave or 40
dplain weave nylon cloth is as STANDARD ADJACENT FABRIC; Step b), in, STANDARD ADJACENT FABRIC is fixedly fitted on a surface of fabric sample to be measured; Step c) the reagent water temperature in is adjusted to 40 ± 2 ℃, and composite sample is put into reagent and stirred 1min with glass bar, and composite sample is immersed in reagent completely.
Further, above-mentioned fabric to be measured is polyesters fabric; Above-mentioned steps only needs STANDARD ADJACENT FABRIC of cutting in a), and this STANDARD ADJACENT FABRIC is peach skin 50
d(300
t~320
t) plain; Step b), in, STANDARD ADJACENT FABRIC is fixedly fitted on a surface of fabric sample to be measured; Step c) the reagent water temperature in is adjusted to 40 ± 2 ℃, and composite sample is put into reagent and stirred 1min with glass bar, and composite sample is immersed in reagent completely.
Further, above-mentioned fabric to be measured is polyester-cotton blend or nylon cotton interwoven fabric; Above-mentioned steps needs two STANDARD ADJACENT FABRICs of cutting in a), and wherein a STANDARD ADJACENT FABRIC is peach skin 50
dplain, another piece STANDARD ADJACENT FABRIC are standard pure cotton cloth; Step b), in, two STANDARD ADJACENT FABRICs are fixedly fitted in respectively the upper and lower surface of fabric sample to be measured; Step c) the reagent water temperature in is adjusted to 50 ± 2 ℃, and composite sample is put into reagent and stirred 1min with glass bar, and composite sample is immersed in reagent completely.
Above-mentioned fabric sample to be measured sampling should be in selvedge 20cm, and fabric sample to be measured is the rectangular block of 20cm * 15cm.
Above-mentioned steps is 200ml for allocating the warm water of reagent in a), and adding the phosphate-less detergent in warm water is 2g.
The invention has the beneficial effects as follows: adopt phosphate-less detergent to make the reagent of concentration 10g/L, by in fabric sample to be measured fixedly attach both standard adjacent fabric make composite sample, in Combinative pattern submergence reagent, carry out resistance to soaked colour fastness test, trace routine simple possible, method of testing science, test result is accurate, after comparing with grey standard scale, can accurately evaluate variable color and the staining grade of fabric to be measured, the resistance to soaked colour fastness method of testing of unified fabric, the resistance to soaked colour fastness grade of being convenient to measure by unified approach is differentiated the quality good or not of textile.
