How to prevent loss of shells elastic cloth during rinsing

Dyeing denim products processing , degradation occurs once spandex and lead to loss of shells, the basic can not be repaired, and must do pre-production sample, to ensure that no quality problems when large-scale production. According to the physical and chemical properties of polyurethane fiber containing spandex stretch denim products due to loss of shells in the washing process, the washing process is mainly due to improper operation or process recipe, resulting in breakage of spandex, dissolution phenomenon, eventually causing loss of shells.

  Rinsing process, because spandex intolerance chlorine bleach, hypochlorite solution in the form of nitrogen - chloro binding the fiber damage, injury polyether-based polyurethane is more serious. Rinsing the cylinder temperature is too high or the time is too long, degradation of spandex will appear, resulting in loss of elastic fabric. So how to avoid the loss of shells during rinsing it?

( 1) do pre-production testing;

( 2) After the production of rinsing water injection cylinder can only be formulated to prohibit the direct feed;

( 3) must be added to rinse water in the device is rotated conditions, caused by high local concentration to prevent loss of shells;

( 4) rinsing water remaining on the laundry release of chlorine leads to the degradation of spandex, do note that the cleaning operation after the high-temperature drying drift over time;

( 5) strengthen personnel management work online, monitor production status, to prevent the processing temperature or time exceeds process requirements caused by quality problems.

  Many people face the loss of such a high risk of playing time will ask, is there a better rinsing fluid loss bullet solution? The answer is yes, of course, Novozymes cold bleaching enzyme solution, rinsing process can be completely solved loss of shells problem because cold bleaching enzyme works only on indigo color, bleach played a role, without any of the other fiber injury, ideal for volatile fabrics bleached shells.
