The company was founded in 1998, a professional Fabric Recycling Machine Manufacturer in China.
The increase of (1) the number of carding carding, because after the amount of fiber feeds the number of drafting areas correspondingly increases, the friction between fast and slow fibers also increases with the stretching process, the fibers help to straighten and eliminate hooks. During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine. Special equipment for the textile industry on the winder.
As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field. The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. Since the draw ratio then increases the total card draft and the main drafting force of the main drafting area is greatly improved, especially in the two even-numbered carding process, in order to improve the straightness of the fiber, it is beneficial to reduce the degree of fiber consolidation.
When using card 8 to be fed, using about 8 times stretching, the degree of fiber straightness is significantly increased, the spun yarn quality index is significantly improved, and the low count rate is uneven. Therefore, the use of the card feed roller feed, a total of 64 combined is convenient. Of course, the lower part of the lower quality yarn rental, still uses six feeds for a total of 36 combined process configurations.
(2) The center distance of the drawing roller company As the center distance of the roller is enlarged, the phytoplankton fiber can be increased, and the fiber straightness can be deteriorated. When 28.6mm looked at the fiber length of the tracing process in the three card type, the distance from the holding roller 35.7 x 22.2 x 42mm to 32.4 x 18.3 x 39.7mm, a significant degree of fiber straightness improved the sliver's Uniformity and silk uniformity are significantly improved. (3) The drafting motion ratio of the carding machine With the increase of the current drafting ratio, the phytoplankton fiber ratio in the reverse effect has a downward trend, and the positive one is slightly different, but the change is not big.
(4) Quantitative quantitative light energy produces good straightness. The process conditions before carding are the same as after drawing, and the amount of drawing has also changed quantitatively. (5) Pushing rollers, for example, in a single apron roving, the effective total skin rolling pressure from 32.6 kg to 40 kg, the fiber straightness coefficient of the roving will increase, reflecting the existence of a significant spun yarn uniformity improve.
When studying the effect of the roughing process on the straightness in the fiber direction, it is necessary to pay attention to the effect of the spinning process on the non-straightness of the fiber. Practical experience has proved that, as long as the front-end technology of the feed product has a relatively high straightness, a relatively small roller gauge and a heavier pressure control device are applied in the front and rear stretch areas of the spinning frame, and a relatively high degree of straightness is used in the bundling. With a small number of process passes, it is also completely different, which can reach and exceed the spinning quality management level of the current enterprises in my country generally including the spinning production process. On the other hand, if the two-stage drawing frame is adopted, the sliver is fed into the sliver direct-spinning ultra-large draft spinning frame in reverse, and the analysis of the spun yarn quality evaluation index can reach and exceed the quality level of a common draft spinning equipment system. In practical teaching application, due to the difficulty of the sliver falling to the society, three draw frames are used, and the combined number is 6 x 6 x 3 (two input and output slivers per eye on a three-lane drawing frame).
In all, in heavy mechanical carding and spinning, and using subtotal and pressure conditions after card approaching 108 times, direct feed to large spinning draft, or using two perforated bar 8 feed, and approaching 64 times And the roving creel is fully capable of meeting the requirements for the fiber straight court.
