Sizing is an important process in warp preparation engineering. 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. 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). Currency quality is closely related to the number of ends and product quality in quilt production. Production practice has proved that if the warp sizing process is slightly negligent, it will increase the warp breakage rate and reduce the production efficiency and fabric quality of the loom.
On the contrary, reasonable warp sizing process can also make up for the defect of poor warp quality. Therefore, the technical requirements of each process of warp preparation are to improve the quality of semi-finished products and improve the quality of sizing. The purpose of quilt production line sizing The purpose of the quilt production line is to improve the weavability of the warp yarns.
In order to weave warp and weft yarns on a loom, warp yarns are usually used first. After the warp yarn is sizing, the warp yarn can withstand repeated friction and tension, bending, impact and other external forces generated by the machine movement, and is not easy to break, which improves the efficiency of the loom. Warp sizing is usually carried out in a sizing machine.
Make the warp yarn pass through a certain kind of slurry, a part of the slurry is immersed in the fibers, the fibers are bonded to each other, and the bonding force is enhanced. , thereby reducing the coefficient of friction and maintaining good elasticity. Typically pitches with large strengths must be sizing as strands may not be as fine as finer strands (eg 9.7texX2) may be due to 0.2% low strength to 2% light sizing to improve warp weaveability. Based on this research purpose, the ideal quality of sizing, sizing and sizing is raised as follows.
With the progress of technological diversification and the sizing of textile raw material structure, the structure sizing machine also has a large development, which further improves the speed and the quality of sizing“5. Automatic sizing process control to shorten the process; the introduction of new technology is waiting. The sizing machine can be divided into the following four aspects according to the sequence of its process. The main contents form a part: the beam creel, the sizing tank, the drying and the yarn separation and winding device. The new sizing machine is also equipped with automatic control devices, etc., with high efficiency and good quality.
