The company was founded in 1998, a professional Fabric Recycling Machine Manufacturer in China.
The Soviet Union considered the comb drum part to be one of those parts that had not been fully studied in the past. 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. 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. Carding the fibers from the feed strip and feeding them into the spinneret is the task of the carding rollers. However, when feedingλWhen there is a fiber bundle pulled out, it is difficult to separate the fibers, and the yarn will be tangled.
The results show that this method can greatly reduce the breakage rate of spinning. This paper studies the essence of two carding processes and their influence on the silver-carding process of the air spinning machine. They emphasize the effect of repeated carding: in the process of repeated carding, the fiber bundles will continue to be decomposed, and the originally fully carded fibers will be further carded. In order to test this hypothesis, the tube carded cotton four times, and all three products are Twentieth lane card sliver reels are made based on feeding, but they are fairly fed on a lap of impeachment.
At the same time, the evaluation also presents the case of carding roughness and separation on fibers during the fiber orientation method. Based on the assumption that by poorly oriented sliver fibers and fiber bundles (ie, less disintegrable fibers) having a structure of high strength, sliver can be evaluated using the following metrics. (1) Strength: It represents the relationship between the development of different fibers (cohesion) and the degree of orientation of fibers along the product.
Determination of sliver strength was performed by breaking 50 mm segments of sliver on a strength management machine. (2) Noil rate of sliver combing: it indicates the existence and decomposition of fiber bundles, the bundle degree and orientation of fibers. Using the card as the test apparatus, 15 slivers (rolls) were fed to each end on the comber to determine the combing noil of the sliver.
(3) The resistance of the fibers when combing the persimmons for the sliver, which can also indicate the presence of different fibers. Using and returning to the Ul-l type tester, the movable lower jaw is replaced by a special crystal needle anti-comb. From the analysis data in the above table, we can draw the conclusion that multiple carding may make the fiber bundles that are not affected by the Xinjinlong 1 flat carding machine during the front co-carding to be carded.
It can be determined that the number of carding also affects the strength of the green and cooked sliver to some extent. With the increase of carding times, the number of defects in the sliver (lint cottonseed skins, neps) decreases. The second time I carded the hard defects (the cotton seeds with lint should) decreased by 18.S%, and the third and fourth times of carding were reduced by 2~3%.
The sliver of the four carding schemes of all students passed through the two-pass carding machine, and was spun into 54.1-mesh spun yarn on the BD-200 air-influence spinning machine. As can be seen from the above table, the strength index (quality index, breaking length) of the spun yarn after two cardings is higher under all conditions, and the repeated carding changes little. In the second scheme, the number of four defects was greatly reduced, while in the latter two schemes it was less.
As the number of carding increases, the number of defects in the sliver entering the air mill and all spinning machines is regularly carded, as shown in Figure 3-63.
