How to prevent artificial yarn defects in the production of grey yarn?

In the spinning process, there will always be losses due to various reasons, there will be some yarn defects, many of which are inevitable. What we have to do is to try to control the losses yarn defects within a reasonable range.

Today we will talk about the problem of artificial yarn defects in the production of linen grey yarn how to prevent it subjectively.

In order to ensure the production quality of linen grey yarn completely eliminate artificial defects, five prevention measures must be taken:

1. Anti change roving (grey yarn) defects: to improve the wrapping quality, it is necessary to remove the flying flowers on the roving surface including the inclined plane. After wrapping, it is necessary to pay attention to that the end of the roving does cover the roving does empty the roving (especially the upper row).

2、 Prevent joint defects: improve the quality of joint, make three checks before joint (check roving, collector stripe dry). In case of white spot during connection, it is necessary to pull off reconnect. The flyback is attached to the yarn, the same end of the roller the cot shall be broken pulled clean. There is no joint for greasy hands (such as spindle belt plate, roller neck, roller seat, rubber stripping roller, steel plate floor sweeping).

3. Warp proof weft proof yarn (grey yarn): pull the empty spindle, put the roving tail in place, prevent the feeding of double roving.

4. Anti tight twist off weft yarn: one hand operation one hand held yarn are strictly prohibited.

5. Prevention of defects in cleaning work: it is necessary to carry out the cleaning operation by hand eyes. Flying flowers are strictly prohibited to attach to the yarn bar, causing yarn defects.

In order to achieve this, it needs skilled operation rich experience of front-line personnel. Therefore, in actual production, it is necessary to strengthen the skill training daily training of the car stopper, the chief engineer the quality supervisor should patrol the workshop every day, report the results of the patrol after the shift, immediately correct incorrect practices bad habits, strictly implement the provisions of the operation law, so as to reduce the yarn made for human reasons Defect, improve product quality.
