The uranium silk spinning system of the air pressure cotton box The raw materials for Myanmar silk spinning are the circular carding machine drops, the carding machine drops, and the spinning itself drops. 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. 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.
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. The filament spinning system is a carding system without drafting and drafting.
Its technological process is similar to waste cotton spinning and worsted wool spinning. The raw materials are first processed with slip cotton, then mixed and heated, and then processed into rovings with a double-roller carding machine, and spun into filaments with a silk spinning machine. The average length of various noil fibers is 25-45mm, and the uniformity is poor, and the impurity content is up to 15%-20%, and the noil is more, and these noil fibers continue to be processed by the silk spinning system, which obviously does not meet the technological requirements. Therefore, generally It is processed into cotton yarn by silk spinning system.
The general number of filaments is 33.3-58.8 tex, which is soft to the touch and has a layer of wooly wool fabric on the surface, called silk fabrics. The post-spinning process of the air pressure cotton box pulls the thin cotton box roving to the suction pressure, spins the spun yarn with appropriate twist, and then processes the yarn, twisting the yarn, into a singeing process that meets the quality index of the finished silk. 1. The spinning and silk spinning frame is also a ring-bonded spinning frame. Its structure is similar to that of the worsted wool spinning frame. The speed of the awl is generally 10000-16000r/min. The fabric is then woven in high gear by centrifugation.
The silk spinning and twisting process can generally be carried out by using a rapid reciprocating doubling machine and a ring bond twisting machine. In order to make the strands have a good luster and soft hand, the strands should be twisted in the opposite direction of the monofilament model. 3. The mercerizing finishing is similar to the sintering mercerizing finishing machine, mainly to remove the surface defects and serious rough details of the silk.
The purpose of burning the silk is to remove the hair on the silk surface, remove the roughness and other adhering sundries, make the silk surface smooth and clean, and increase the luster. The number of overfires on the singeing machine and the number of singeing methods affect the singeing effect.
