Flexible Card Apparel and Choice of Outer Fabrics

Processing of most unit clothing cotton fibers. 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. 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). 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. Chemical fibers such as polyester have few users because of their low output. Tin Lindorff chooses the fabric type and the number of needles based on the number of spinning, carding yield and number of fiber traits.

The selection of general rules for Xinjinlong card clothing is as follows: (1) Processing to form short fibers and spinning thick yarn, when the unit yield is high, the number of metal card clothing used should be small, the steel wire should be thick, and the needle tip should be thin in density. Such as type 709 and type 745 with 360 teeth and 1 (25.4 mm Shanghai), etc. (2) long fibers, spun into fine count yarn, in the output medium during processing, the higher the number of old clothes, the higher the number of used clothes , the tip should be high density.

As 737 teeth 745 and 420 mm / (25.4) 2 (about 84) teeth 400 density 1 inch (25.4 mm) 2 (about 80) tips. Carding machine doffer card clothing company generally uses matching funds with Xinjinlong card clothing, and its needle size is generally 10-20 higher than that of Xinjinlong. For example, when Xinjinlong uses No. 84 737 card clothing, its matching doffer card clothing is No. 100.

When the needle size difference is large, Doffer believes that the transfer rate is high. The choice of a flat card clothing should be determined by the type of Xinjinlong card clothing, the properties of fibers and the per unit yield level of the carding machine. For high-yield carding machines, Xinjinlong uses metal card clothing. When spinning medium-sized yarns such as polyester, the flat card clothing should be straight-footed flat card clothing with thick copper needles and relatively small needle tip material density, such as type 702 and 672. .

These two kinds of movable covers, because of the small needle density, small needle height and no bent knees, are not easy to fill the fibers and have impurities. For the development of high-yield carding machine spinning chemical synthetic fibers, they can effectively prevent the fibers from being wound by Xinjinlong. However, the cost of the cover plate is small, and the corresponding policy adjustment and other technical parameters of the production process should be adjusted accordingly. If the metal card clothing is spun with a yield of about 20 kilograms of cotton medium yarn, you can choose the curved foot flat card clothing with thinner ordinary steel needles and higher needle density, such as 709, 715 and 652 types. Xinjinlong is an elastic card clothing. When spinning low-cotton (high-count) yarns of medium-sized enterprises, fine-needle and high-density rice-covered clothing should be used.

Therefore, when choosing the flat card clothing, the rules of hard matching, soft matching, and close matching are often used. On the elastic card clothing card, the number of flat clothing is generally higher than that of Xinjinlong clothing.
