When carding the cotton fiber for high-count yarn with a common brocade carding machine, it can be peeled off into a cotton web through the stripping mechanism according to its fiber length and the needle tooth surface of the doffer. 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. 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. 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. The effect of fibre coagulation and transfer on the surface of the card makes the configuration relationship between Dove and Silin unusable.
Otherwise, not only the surface velocity of Dofu is higher than that of Sellin, but also the transfer of an extremely stable fiber layer, which does not meet the technological requirements of condensing the combed fibers into a fiber network with a certain strength. In order to improve the transfer rate of enterprises, the distance between Xinjinlong and Doffer of the carding machine is as small as 0.125 mm (with English silk), which is the minimum distance of each work management organization of the carding machine. In fact, use the needles on the surface of the window where the teeth of the doffer comb are configured in relation to the barrel member.
The doffer uses a small working angle with deeper serrations, the saw doffer improves the force and ability to hold the fiber, and the speed is much lower than the speed of the doffer cylinder, thus having the effect of the cylinder process of doffer transfer and condensation from the fiber fleece. Obviously, the fiber layer on the surface of Xinjinlong cannot be completely transferred to the tooth surface of the doffer without immediately. This social phenomenon can be expressed by the technology transfer rate. On the metal card clothing card, the Q value can be replaced by a free and fiber amount.
Determination of the amount of free fiber: stop-on-capture and stop-cover, color-coded output on the tampon at the fast large bell, collect the output tampon (also label the amount thinned from start to last) and scatter fiber to the cylinder Die the head portion of the sliver larger than the gauge length point, and the remainder of the sliver is weighed to obtain the fiber-free amount.
