1. Objectives of the experiment 1. Experimental method to learn the effect of uniform mixing of cards. 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.
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. 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.
2. Experiment to gain an in-depth understanding of the role of the carding machine for uniform mixing. Second, the basic knowledge of carding Xinjinlong and covering the active area has good carding performance, and can even play a role in mixing. Cylinder and has a fiber, when feeding a thick slice of human body knee, it can absorb part of the fiber absorption and emission characteristics are stored in flat garments, thin loop segments of the face, can release part of the fiber to compensate.
The result of the combing of the output of short segments of sentences was improved. At the same time, in the working area of the cylinder head, the transfer characteristic between the barrel and the needle with two surfaces is constantly repeated, after a series of piercings between the flat surfaces of the flat surface of the delivery cylinder into the active area of the fiber, The fibers are transported in multiples, the fibers are fed by the cylinder head barrel into multiple workspaces to carry all the output fibers and carry to the cylinders in the cylinders and doffer active zones, and the fiber distribution is output to multiples within the licker-in cylinders. As an input, the drum accepts turns of fibers to be mixed together, thereby achieving a mixing effect between fibers. Some dyes of this experiment were fed to cotton and cotton quality double carded, fed and measured time dyed cotton output, a mixture was observed between the shells, where the color change and the mixed tampon single fibers, thus analyzing the mixing effect of the two color treatments Carding; Quantitative determination of the change in the bilayer of sliver feed output to analyze the effect of uniform carding.
Third, laboratory equipment and appliances, cards, stopwatch 3, box feet, a balance, dye a circle, from a circle, a cylinder length measuring machine, with a rectangular tear dye lap (row width 150mm, length 1000mm) one board. Fourth, the experimental content 1. Prepare (1) the washing machine (copy car, remove the cover, clean the belly of the whole locomotive, etc.). (2) Stained lap joint outlet 1M, restrained rectangular piece of wood 150mm X 1000mm.
Run along the torn edge of the board dye stock lap. Note tear together as much as possible, without accidental elongation. (3) The white circle is gently withdrawn by 2 meters.
The resulting dyed circle is covered and then rolled up on the lap rack. 2. Driving operation After 20 minutes of driving operation, there is no parking space for a sliver. (4) Measurement of layers starting dyeing The sliver is fed to the starting time to see the dyed fibers.
(5) The time when the dyed fiber sliver is seen to be substantially white from the measurement of the initial sliver. (6) Feed batt time from measurement of feed dye. The tampons from experiment (7) were cut into cylindrical lengths measuring 1 m long segments as in 3. The tampons for all experiments were weighed according to the cross-section and recorded in the order of segments in Tables 2-6.
(8) Please note that the tampon and tampon are weighed in reverse order. (9) When each segment of the tampon is weighed, observe the change in the number of fibers of the dyed sliver. Website keywords: Carding line card box quilt.
