Vortex spinning The vortex spun yarn is similar in nature to the ordinary ring spun yarn, but the take-up speed is 20 times higher than the ordinary ring spinning take-up speed and 3 times the rotor spinning take-off speed. The quality of the vortex yarn is not as good as that of the ordinary ring yarn, but the vortex yarn is close to the quality of the ordinary ring yarn when the higher speed increases the output. The MVS vortex spinning machine produces a spiral gas from two rotating nozzles to push the cooked strip around the fixed spindle to create twist and form the yarn. One end of the loose fiber is twisted around the lapped fibers to form a true enamel. The vortex yarn is similar to a conventional ring yarn. The yarn is divided into two parts, namely the inner core and the outer layer of the yarn. The outer layer is wrapped with fibers, and the fibers surround the inner core to form a wrapped yarn, which makes the yarn very strong. The vortex spinning system is fully automat...

Polyester fabric is a kind of chemical fiber fabric used in daily life. Its biggest advantage is that it has good wrinkle resistance and shape retention. Therefore, it is suitable for outerwear such as jacket clothing, various bags and tents. Advantages and disadvantages of polyester fabric: First, the polyester fabric has high strength. The short fiber strength is 2.6-5.7 cN/dtex, and the high-strength fiber is 5.6-8.0 cN/dtex. Because of its low hygroscopicity, its wet strength is almost the same as the dry strength, and the impact strength is 4 times higher than that of nylon. Viscose fiber is 20 times higher. Second, the elasticity of polyester fabrics is super strong. The elasticity is close to the wool. When the elongation is 5% to 6%, it can be almost completely recovered. The polyester fabric is repeatedly twisted, and the original shape can be restored quickly without leaving wrinkles. The elastic modulus is 22 to 141 cN/dtex. Nylon is 2 to 3 times higher, which is unmatc...

Fabrics are mainly divided into: non-woven fabrics and textile fabrics. From another dimension, it is divided into natural fabrics and non-natural fabrics. See nature from a finer dimension a. Plant fiber, such as: cotton, hemp, fruit fiber b. Animal fiber, such as: wool, rabbit hair, silk c. Mineral fiber, such as: asbestos Unnatural a. Recycled fiber, such as: viscose, acetate, Tencel, Modal, Lessel, bamboo fiber, etc. b.Synthetic fiber, such as: nylon, polyester, acrylic, spandex, Lycra, etc. c, inorganic fiber, such as: glass fiber, metal fiber, etc. (to facilitate understanding of the above trade names and large class names have mixed phenomenon) 2. From the perspective of textile technology: woven: The fabric structure is stable, there is no elasticity (except for the fabric added with elastic fiber), the cloth surface is flat, solid and durable, the appearance is crisp, there is looseness, simply speaking, it is not close to the body, and it is broken. Knitting can not s...
