What are the ways and measures to control spinning quality

1. Reasonable configuration of opening and cleaning, carding and combing processes The effect of reducing the content of short linters on the quality of spinning products. Because in the drafting and floating zone, those shorter fibers cannot be effectively controlled, and large shift deviations are... read more

What are the factors affecting spinning quality

1. Raw materials Before spinning production, the spinning raw materials must be carefully selected, the ratio of cotton blending and blending must be coordinated, and the fibers must be fully mixed together to meet the needs of spinning production. 2. Craft In the spinning process, the quality of sp... read more

What are the causes and elimination methods of the draw frame coiling effect

The "coil effect" of the draw frame is a common and frequent problem in the pre-spinning drawing process The coiling effect wave can be eliminated naturally in the tension drafting of the later process. Although it does not affect the quality of the yarn, it makes the calculation value of the drawin... read more

How to improve the control effect of yarn quality

Control measures when occasional yarn defects and frequent yarn defects are not high and the DR% value (±20%, 0.01m) is high Sometimes we will find that the occasional and frequent yarn defects are not high in the test, but the evenness CV% is high. At this time, if the DR% value (±20%, 0.01m) is te... read more

What are the control measures when frequent yarn defects are high

When there are many frequent yarn defects and the DR% value (±20%, 0.01m) is too large, the control should be strengthened mainly from the aspects of raw materials, process parameters, mechanical conditions, operation management, temperature and humidity. In terms of raw materials, spinning material... read more
