What are the characteristics of compact spinning? What are the advantages and disadvantages of compact spinning?
Advantages:
(1) Good pilling resistance
Fabric pilling is closely related to the hairiness of the cloth surface. Fabrics produced using compactly spun yarns have less hairiness on the fabric surface and significantly better pilling resistance than traditional ring spinning;
(2) Good evenness
The straightness of the fibers in the sliver is improved, and the yarn Line dryness is better evenly.
(3) Wear resistance
Compared with traditional ring spinning, the fibers of compactly spun yarn are arranged neatly and straightly. The yarn structure is tight and the fibers are not easy to fall apart, so the yarn has good wear resistance.
(4) High strength
Yarn strength depends on the number of fibers in the yarn and the cohesion and friction between fibers. Compact spinning has less hairiness, and the number of effective fibers in the yarn is more. In addition, the fibers are neatly arranged and tightly coupled, resulting in high yarn strength. Compared with traditional ring spinning, the strength of compactly spun yarns is increased by 10% to 25%.
(5) Less hairiness
The hairiness of traditional ring spinning is mainly generated in the twisting triangle area, while the triangle area is eliminated in compact spinning, and the hairiness is greatly reduced. Production practice has proved that the hairiness of compact spinning yarn is reduced by 70% to 80% compared with traditional ring spinning.
(6) Small twist
Due to the increased strength, the yarn twist can be appropriately reduced, generally 20% lower than ring spinning, thereby increasing yarn output;
Disadvantages
(1) Large investment in equipment
(2) High startup costs
(3) Strong cleaning work
