The amount of small rolls should be reasonable

Magnolia Polyester Yarn

The main tasks of the preparation Magnolia Polyester Yarn: (1) Initially improve the parallel straightness of the fiber. The third preparation process method has been widely used because of the large number of merging and total draft, which improves the uniformity of small rolls and fiber straightness, and is more conducive to combing by the comber. Combing The quality control points of the preparation process (1) The quality of the small rolls is better. Combined with the test of the nodding content, reasonable control of the nodding rate, as low as possible under the premise of meeting the quality requirements. (3)

The amount of small rolls should be reasonable. (4) Merging, uniform mixing and strip feeding The combination of times makes the fibers in different slivers fully mixed and uniform; and it is made into combed slivers for processing in the next process. ② Normal law, Whether feeding cotton forward or backward, the length of the cotton is long, the output is high, and the quality of the web is poor; the length of the cotton is short, the output is low, and the quality of the web is good. (2

) Made into uniform small rolls Produced into large-capacity, quantitatively qualified, neat edges, small and uniform cotton rolls for the comber. Testing the quality of the combed sliver according to the cycle to reduce the difference in the table and the eye is an effective means to control the quality of the combed sliver.The product quality control of cotton spinning enterprises is a continuous, complex and interrelated textile system project. The output is high when the quantification is high, but it affects the carding quality. The quality of the combed sliver is positively correlated with the quality of the finished yarn.

The small rolls must have a uniform structure, clear layers, non-stick rolls, and good fiber orientation and straightness. (2 Eliminate impurities and neps in the sliver to reduce spun yarn ends and yarn defects, and improve the appearance quality of the yarn. It is important to control the number of combined roots and total draft multiples. (5) The main task of the comber to control the neps, impurities, and short pile rate of the combing bar is to eliminate the short pile , Neps and impurities. The backward cotton feeding method has a significantly higher rate of cotton fall than the forward cotton feeding method.
