Wild cards are mainly used for soft stitches, carded waste cotton, cotton, asbestos fibers, and fabrics such as raised and carded are rarely used. 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.
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. Regarding flat clothing, foreign schools and more flexible and rigid flat clothings, but hard metal flat clothings are also being developed. For foreign copy needles, the card clothing brush should also pay attention to continuous transformation.
The HL and LP type yarn clothings produced by Jinbing Industrial Enterprise Company for Carding Machines can be used for sand cover and metal clothings respectively. Figures 1-26 are reproduced with HL-type needles and tissue distribution #F columns. The characteristics of this copy card clothing are: (1) Due to the time length of time, the steel wire needles are alternately arranged, and the number of needle points that can be connected to a flat card clothing is limited, which can prevent the most needles from being copied and protect the metal card clothing. .
(2) The section of the steel wire is short, and the side of the needle tip is completely scratched. Seed crumbs, leaf shoulders, cotton neps and other impurities are all closed and locked, you blame the needle for grasping, the length is matched, and the effect is good. (3) Long service life, the service life of rectangular yarn clothing is 6 times.
Figure 1-27 is a needle and weave arrangement of LP yarn types. Such sand is characterized by an oval shape in the clothing section, with the large work being strong upwards. Normal life is to duplicate the rounded card clothing twice.
