  The process of combining yarn is the preparation process of yarn twisting or yarn doubling. However, two or more yarns are twisted, resulting in a yarn of higher strength, greater uniformity, special color combination and special structure. From a single yarn, the production of twisted yarns is divided into two stages: several yarns are first combined on a spinning machine, and then twisted together on a twisting machine. The weaving process is the first stage and the twisting process is the second stage. When using double twisting machine or ingot can twisting machine, with three or more yarns to produce twisted yarn, the process of merging is essential. For two strands of yarn, there are two process lines that can be applied in double twist: First, the classic method of double twist winding is used. The second method is to use two single yarns rolled up and down the double supply of yarn rolling placement. What is the use of  twisting machine ? Double twist machine is a kind of twi

  What is the principle of rotor spinning machine? Rotor spinning is a new spinning technology which uses air flow to condense and twist fibers in a spinning cup with high speed rotation. He does not use spindle, mainly rely on comb roller, spinning cup, false twist device and other parts. The carding roller is used to grab and comb the feed of the cotton strip fiber, through the centrifugal force generated by its high-speed rotation can throw out the grabbed fiber. The spinning cup is a small metal cup that spins more than 10 times faster than the comb roller. The resulting centrifugal action pushes the rotor out of the cup. According to the principle of fluid pressure, make the cotton fiber into the rotor cup, and form the fiber flow, along the inner wall of the cup constantly movement. ​ What is rotor spinning machine? Unlike ring spinning, rotor spinning does not use spindle twisting, winding and forming. It mainly relies on several parts such as carding roller, spinning cup and fa

  What is ring frame machine? Ring frame machine: a spinning machine in which half products of roving or sliver are drawn, twisted and wound into muslin in the spinning process; sliver is drawn and twisted on a roving machine to make roving; a combing machine to carding fibers into combing slivers; a needle carding machine to combine slivers; needle drawing improves sliver structure; roving is further twisted into muslin on a ring spinning machine; spinning machine is the main machine for spinning. The output and quality of fine yarn are the comprehensive reflection of each process of spinning technology. What is the importance of  ring frame machine ? The spinning process is the last process of spinning, but also an important process of the textile factory, the total number of spinning process is an important symbol to measure the size of the cotton textile factory and production capacity, the output of spinning process determines the textile factory each process of mechanical equipme

The main function of the roving machine is to draw and twist the fiber strips into roving to meet the requirements of the spinning frame processing. What is roving used for? The mature strips made by drawing frame are relatively heavy and must be drawn 50 times to 400 times to reach the required fineness of yarn.At present the spinning frame does not have such a large drawing capacity. In the 1950s, it was tried to spin the cooked strips directly without roving process by using a large draft spinning frame.Due to excessive draft, the short length of yarn will deteriorate. At the same time, feeding the spinning frame directly in strip form will encounter difficulties in many aspects and is not economical. Therefore, in the traditional spinning process, in order to ensure the quality of yarn, a roving process is set between the jointing and the fine yarn to share part of the draft.However, new spinning technologies, such as rotary spinning, jet spinning, friction spinning and dust cage s

One of the most significant pieces of equipment in the long fiber processing system, such as worsted wool spinning, is the gill box machine. Because the fiber straightening parallelism and evenness of the slivers generated by the roller carding machine do not match the spinning criteria, some of them still have the “hook” phenomenon and cannot be spun directly in the long-staple spinning system. As a result, the top is processed and transformed using a gill box machine. The gill box machine carding process is a crucial step in the wool spinning process. The purpose is to improve the parallel stretching degree of the fibers and improve the structure of the sliver through merging. The working state of the gill box has a very close relationship with the output and quality of worsted wool spinning. The main tasks of gilling process Several merging and drafting improved the homogeneity of medium and long sliver parts; Straightening parallelism and fiber separation are increased further by c
