Some problems on grey fabrics have been exposed until they are dyed. This is also a phenomenon that occurs in printing and dyeing factories. For example, indigo yarns exhibit color points and stains after dyeing with light-colored vat dyes, as well as blanks, aurora, scratches, abrasion marks, and stain-repellent stains on grey cloth surfaces (caused by waxing during weaving of grey fabrics . ) Such defects can not be easily detected during the blank inspection, and are not easily found after cooking and bleaching, but they can be clearly displayed after dyeing. In addition, the vast majority of fabric packaging creases have little effect on the quality of printed products, but there are also a small number of dead marks that can be clearly seen after dyeing.
If there is only a single defect for each cloth, the fabric score is within the normal range, and there is little impact on the clothing loss. If the frequency of occurrence is too high, the finished cloth score may exceed the allowable range, resulting in the customer not accepting large goods. The printing and dyeing plant should arrange for the first-time product quality controller (QC) to perform on-machine inspection of the dyed finished products of the dyed machine and to score according to the standard, so as to judge whether the semi-finished product of the single product can continue to be dyed. If the customer is processing blanks, the printing and dyeing plant should also report the customer at the first time after the suspension of the dyeing process, and negotiate opinions.
