placing the sample in a water tank, heating to 60 ℃, adding 10g/L desizing enzyme, washing for 45min, after the water washing is finished, passing clear water for 3min, and then dehydrating;
rolling and drying the detection sample (the drying temperature is not more than 70 ℃), blowing cold air for 5min, and standing for half an hour;
measuring to obtain an average value after the washed radial dimension = warp three-position mark measurement;
latitudinal dimension = average value of measured latitudinal marks;
the values of the shrinkage from sample one to sample seven obtained from the shrinkage = (size before washing-size after washing)/size before washing × 100% are shown in table 2:
TABLE 2
The yarn formed by weaving cotton fiber, fibrilia and bamboo fiber is mixed into the mixed yarn by color fastness test and shrinkage detection, so that the shrinkage of the whole mixed yarn can be reduced by depending on the low shrinkage performance of the bamboo fiber, and the carboxyl and/or aldehyde group in the solution of the mixed yarn can be utilized by depending on carboxylic acid or formaldehyde acid, the active hydroxyl on the original cellulose can be replaced by depending on the two negative groups, so that the cellulose fiber can be combined with cationic dye more firmly, and better wet fastness and color fastness can be achieved.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
