Poor network of DTY yarn

For overall network defects, methods such as increasing network air pressure, selecting appropriate nozzle models, adding 2BIS rollers to improve yarn tension stability, adjusting yarn holes to reduce single thread density, etc. can effectively improve the overall fastness of the network, while also improving the overall water level and reducing the probability of single spindle network defects.

The main reasons for poor single spindle network are nozzle blockage or equipment defects. Self inspection of equipment defects through appearance is the only way to reduce single spindle network defects, such as tension differences caused by rust or looseness of the first and second rollers, nozzle hole blockage, and nozzle not closing.
