Description

High-speed spinning device capable of reducing hairiness

Technical Field

The invention relates to the technical field of textile equipment, in particular to a high-speed spinning device for reducing hairiness.

Background

Spinning is an ancient activity, and since the prehistoric times, mankind has become aware of spinning shorter fibers into long yarns, which are then woven into fabrics. Spinning is the practice of using animal or vegetable fibers twisted together into a continuous, infinitely extending yarn suitable for weaving. The twist of the yarn itself will cause the fibers to naturally and tightly bind together, thus making weaving or knitting very advantageous. Where the twist of the yarn is related to the diameter of the yarn, the measure is determined by the number of turns in each inch of yarn and is expressed as low, medium or high, generally the higher the twist, i.e. the more turns of the yarn, the better the strength of the yarn. Low twist yarns are commonly used to make smooth, glossy or soft, matte fabrics; conversely, fabrics with a wrinkled feel or rough surface require high twist yarns to make. The types of spinning can be classified into ring spinning, twist-less spinning, self-twist spinning, centrifugal spinning, cap spinning, open-end spinning, air-jet spinning, electrostatic spinning, vortex spinning, air-jet spinning, friction spinning, etc., mechanical spinning has an advantage of high yarn strength, and air-jet spinning has an advantage of high speed.

Most mechanical spinning has the disadvantages of slower spinning speed, and air-flow spinning has the disadvantages of lower strength and longer hairiness of spun yarns.
