(1) The quilt production line passes the relationship between the draft ratio and the draft force ① When the mark or the same number of fibers are fed into the sliver, the relationship between the draw ratio and the proportional draft force is shown in Figure 4-14. 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. When the draw ratio is equal to 1, i.e., the figure does not occur, there is no sliding between opposing fibers, and the draw force is zero. Thereafter, the sliver deteriorates as the draw ratio increases, and thus the draft force increases rapidly with the draw ratio.
When the draw ratio approaches Ec, slippage between fibers begins. The slip increases from the fiber-less process, the main draw optional lux E with the Ec draft multiple being added slowly, the quilt line drawing force before the tunnel is lowered to reduce the number of fiber jaws. EC At the point of maximum pull-out force, the draw ratio is called a critical draw.
Experiments show that the critical sliver is drafted with Ec = 1.2 --- 1.3, but this is not fixed. When feeding the sliver or basis weight, the number of changes in the roll gap and parallel straight fibers and others, the critical force draft value and the corresponding maximum number of changes are also plotted. ②When the number of output sliver or fiber quantity is maintained and changed, and the number of feeding sliver or fiber disc is changed, the drafting motion multiple is large, which means that the feeding sliver is thick or fiber is studied the most, and the rear jaw The frictional force on the sliver has been developed and expanded. Although the relationship between the number of fiber cells in the front tongs remains unchanged, the resistance of each fast-enhancing fiber when it can be pulled out continues to increase, and the drafting force also increases the cost accordingly.
