In order to produce high-quality nylon yarn, it is necessary to first process nylon 66 chips. These chips need to be increased in viscosity by a drum and their moisture content needs to be accurately controlled. This is because nylon 66 chips usually need to be dried before spinning to remove surface moisture. However, if the moisture content inside the chips is too high, bubbles are likely to form during the melt spinning process, which can cause hairiness and broken ends, seriously affecting product quality and yield.

[0003] Therefore, in order to ensure the smooth progress of the spinning process and the quality of the final product, the moisture content of nylon 66 chips must be controlled within a suitable range.
