How to maintain PP yarn? The maintenance work of PP yarn mainly includes the following 3 points:

The first method is to make the yarn soft through traditional mechanical methods, mainly after the soft yarn treatment, the glue film is destroyed to show the softness. The disadvantage is that this method easily leads to pilling of PP yarn.

The second method is to increase the moisture regain of PP yarns, but pay attention to the range. If the test in a large area will cause the polypropylene yarn to mold, and the softness improvement is not obvious. Or add an appropriate softener during the spinning process, which can also improve the softness of the yarn.

The third method is similar to the second method. It softens the roving, also called roving oiling, softens the glue film mentioned above, and then uses a softener to improve the softness of the PP yarn.
