Concentration spinning is a new type of spinning technology in which a concentrating device is added before the drafting device of the ring spinning frame to perform spinning. The spinning mechanism is mainly: a fiber aggregation zone is added before the traction device of the ring spinning frame, a...

Different spinning technology has different effects on the physical properties and appearance of the yarn, and even makes the characteristics of the final product different. At present, the five practical spinning processes of ring spinning, cluster spinning, rotor spinning, air-jet spinning and vor...

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...

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...

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...

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...
