Many types of cotton yarns are widely used and divided by product specifications including: quilt production lines thick and fine specialty yarns; carded and combed yarns and F-chain; specialty yarns, with various blended yarns? card etc. 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. 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.
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).
Depending on the use of point yarns, include: warp and weft, pile yarns, knitting yarns and the like. . According to this it is also an aspect of the finishing process like Open 10 Kam beater can opener.
Mixed into channels 9, each in turn overlapping the output bins of material, the blend is complete, the outboard chimney 8 cotton output stream. The main features of the quilt line FA022 type machine is a multi-compartment sponge: through sequential steps with cotton air, through the cotton flow feed box, storage, output synchronization, multi-bin blending. Air-freighted cotton fibers with high density and high capacity by compressed air in the box.
At the same time, the long-delayed output time effectively solves the long-period uneven rod and each box is not fed to ensure the stability of the mixing ratio. While the output is evenly distributed into six parallel vertical cotton boxes 2, the airflow leaves from the reticularity in Figure 3-7, and the cotton is lifted through the duct as shown in Figure 3-7. The box structure of the multi-FA025 quilt line agitator is shown in Figure 3-7. After six boxes tightly? The batt-induced curtain falls on the conveyor belt 3, and is classified by different ligands to cotton, J according to different working conditions.
Selection of suitable raw cotton. 1. Special and more detailed description of cotton yarns with different densities, exposure to impurities will make the surface of the neps yarn more tender and increase the relative yarn defects. When t cotton yarn should choose extra fine grade high density j money thin, long length, short fiber defects and raw steps;. extra thick yarn should choose a lower grade,; short degree; lower quality? Raw cotton part can be mixed, Then put down the batting.
2. Hang has combed yarn and fine yarn - higher combed appearance requirements, better uniformity, impurities, usually need to correct the combed circumference, good grade cotton. During processing, combed yarn can be excluded more short fibers, the uniformity of fiber length is improved, and therefore contains slightly more whip cotton linters with no significant effect on yarn quality. The neps of sawtooth cotton generally contain a lot of plated cotton combing, which is difficult to exclude and cannot be used for many times.
If the maturity is too poor, the moisture content of Yuannan is high, and it is easy to neps during processing, so it should also be avoided. The requirements for combed yarns equipped with raw cotton are also relatively slightly lower than required for carded yarns.
