Tasks in the combing process of the card

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

There are many defects in the carding sliver, as in the sliver, the fibers are not completely separated, the fiber parallelism is poor, and the hook fibers are more (the fiber straightness of the common sliver is 50-60%), and the fiber length difference is larger. (Short fibers below 16mm account for 14-18%), and there are many neps, impurities and defects. Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery. According to the spinning process, carding is an important process.

The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process). 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. Grinder A spinning machine that turns fiber strands into rovings.

The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame. Combed yarns have always been used instead of combed yarns for textiles that require quality checks, such as fine-cut jerseys, thin premium undershirts that are cool and uniform, and soft, fine-grained poplins. In addition, most of them also use combed yarns, such as electrician notices, tire ropes, aviation ropes, pagoda threads for high-speed sewing machines and embroidery threads for Chinese folk handicrafts.

This is because the combed yarn is superior to the same special carded yarn in terms of mechanical properties and appearance gloss. The card is combed into spun yarn by the comb handling system. Carding is one of the essential key processes, and its main tasks are, (1) to further separate the fibers and lift off the straightening and parallelism of the fibers in the sliver to increase the light selectivity of the resulting yarn, (2) ) The length of the smaller negative short fibers to improve the uniformity of the fibers, so to reduce the hairiness of the yarn, the yarn strength is improved.

(3) To further develop and eliminate cotton spinning, impurities and defects in tampons, and to improve the yarn quality in many ways. (4) To make the combed sliver dry more evenly. The combing of the carding machine completes the above tasks, that is, the raw sliver is divided into small rolls through the preparation work, and then combed, so as to more thoroughly eliminate the short fibers, cotton spinning and impurities in the cotton layer, so that the straightness and parallelism of the fibers are improved. and peeling degree was significantly improved. Of course, the combing effect is closely related to the combing noil, because the combing machine has a large amount of noil in the process of grasping and combing, and usually has a certain combing effect under a certain noil rate, so it is impossible to propose an infinite combing effect. Require.

Under normal process conditions (12-14% of the number of combed sliver), the effect of carded sliver is, (1) 42-48% repellency of short fiber sliver compared to carded sliver. (2) Minus 50-60% impurity sliver, (3) Eliminate 10-20% neps in the raw sliver (mostly large neps) (0 The straightening of the fine sliver and the parallelism can reach 85-95% Therefore, compared with the brocade brocade yarn with broad 'belt', the strength of the tip-collared yarn is 10-15% higher, the cotton thread impurities are reduced by 50-60%, the sliver uniformity is significantly improved, and the quality evaluation index can be improved by more than 10%.

It makes the combed yarn have the characteristics of good light selection, uniform sliver, less knots, and strength quotient.
