When there are many frequent yarn defects and the DR% value (±20%, 0.01m) is too large, the control should be strengthened mainly from the aspects of raw materials, process parameters, mechanical conditions, operation management, temperature and humidity. In terms of raw materials, spinning material...

Raw material yarn defects are mainly caused by occasional yarn defects caused by poor raw material length uniformity, large difference in fineness, high short-staple rate, low maturity, neps, leaf chips, cotton seed hulls, and high fiber-bearing seed chips. The control of raw material yarn defects s...

Electronic yarn clearer is the last pass to reduce yarn defects and ensure yarn quality. The setting of the process parameters of the electronic clearer not only affects the final quality of the yarn, but also a direct factor affecting the production efficiency of the winder. Therefore, the setting ...

1. The characteristics of knitting engineering and its requirements for yarn thickness and detail Knitted fabric is made by using knitting needles to turn each yarn into a loop, and then weaving the loops in tandem. The structure of knitted fabric is loose, and there are more gaps inside the yarn lo...

The quality of temperature and humidity environment control directly affects yarn breakage. Many companies only focus on temperature and humidity in their understanding of the environment. In fact, in addition to temperature and humidity, the number of air changes in the workshop, air cleanliness, s...

Special parts for twisting equipment a. Spindle Spindle is the core component of winding and the key equipment to realize high-speed spinning. The basic requirements of high-speed spinning for the spindle are: ① stable and reliable operation, low noise, generally in 25kr/min space-time spindle vibra...
