Generally, it can be remedied by the method of reburning hair, but it should be noted that a large sample can be tested first to prevent the finished fabric from passing through the crater during the reburning process, which may have a certain influence on the color of the cloth surface of the dyed fabric.
Second, the former is poor
Mainly refers to the process of boiling and bleaching process is not in place, such as desizing is not clean, scouring may not be transparent, resulting in uneven dyeing, color in the edge and other defects. This problem can be solved if it is difficult to handle in dyeing workshops and returned to the pre-treatment workshop where it can be boiled ( or lightly cooled). The reason for judging the occurrence of this kind of rickets is the problem of the pre-treatment workshop or the dyeing shop. The printing and dyeing factories have their own set of verification methods, so it is not difficult to distinguish the responsibilities.
Third, before and after color
The reasons for the color difference before and after the pretreatment process may be the following: First, the fluctuation of the concentration of the mercerized alkali is beyond the allowable range of the process, and the difference in the degree of mercerization before and after the fabric causes the color difference between the front and the back of the dyed cloth, especially for fabrics with low concentration of mercerized fabrics. More sensitive; Second, brewing and bleaching machine, mercerizing machine sometimes stop for different reasons, the fabric can not be normal continuous operation, parked in different positions of the fabric after dyeing may have before and after color, usually this kind of parking will be accompanied by a parking block The third is the color difference between the front and the back of the brushed cloth due to the fluctuation of the brushing process or the shutdown of the equipment.
Fourth, the fabric crease
The occurrence of wrinkles on the fabric is the most common problem for pre-treatment machines (including mercerizing machines). In general, the creases of pure cotton fabrics need to be repaired by multi-filament yarns , and the polyester/cotton blended fabrics need to be repaired by re-setting and minor wrinkling can be achieved. It will be difficult to repair it if it is repaired. Relatively speaking, if it is possible to change the repaired semi-finished products into bleached or light-colored fabrics, the impact on the quality of finished products will be relatively small.
Fifth, the cloth hole
The defects that may also occur during the pre-treatment process are regular holes. This is because the fabric may have foreign objects embedded in the rubber rollers when it is pressed by the machine rollers. This will cause the fabrics to be regularly broken. hole. Just measure the distance between the holes and find the rubber roller in question to find the root cause of the hole. In addition, in the setting process, there is a possibility that the needle on the edge of the cloth is defective or the hole of the eye is broken. Mostly, the needle is not adjusted or the needle is broken, and the problematic needle plate should be promptly disposed of and replaced.
If an irregularly gypsophila-type hole is found on the surface of the cloth, it is likely that the singeing or oxygen bleaching process has a problem, and the possibility of an oxidative hole that occurs when the oxygen drifts is greater. Once it is found, it is necessary to immediately stop and thoroughly inspect. You can do oxidized cellulose test or measure the strength of smashing to determine the cause of the hole.
Once there is a hole in the cloth, it is difficult to remedy it. For small holes with small number of broken yarns (such as small holes in linen fabrics), as long as the repair cost is within the allowable range, professional repair personnel can repair them with manual darning to reduce the number of defects. Loss of quality. This is also the last remedy.
