01 causes of yarn pollution
a. Caused by mechanical lubricating oil
Oil stained yarn is caused by mechanical lubricating oil.For example, if too much oil is supplied to spindle rolling bearing or 6001 6002 rolling bearing, unnecessary oil contamination will be thrown out during the whole process of high-speed operation of spindle, which will cause yarn pollution, which is not clean.Naturally, there is very little chance of this happening.
b. Dust pollution
During the operation of yarn in the spindle channel, because of the working environment and dust accumulation inside the yarn, a layer of dust will adhere to the spindle yarn channel during the operation;Because of the sudden change of working environment temperature and humidity, condensation water will occur in the yarn channel;At the end of the yarn, due to the change of unwinding support force, the yarn will change its original line in the channel.At this time, even the fire hose dust will be taken out, the yarn surface will produce gray black, similar to vegetable oil appendages, but the dust pollution can be cleaned away.
