Fiber combing is a process in which a combing machine is used to remove short cotton fibers (under about 10mm) and impurities during the cotton processing process, leaving longer and neat fibers. The yarn produced is smoother, more delicate and It is not easy to pill, and because the process is complicated and exquisite, the cost is high and the price is expensive.
1. Ring Spinning:
Ring spinning is a conventional yarn spinning method where fibers are twisted and wound onto a bobbin through a ring and traveler mechanism. This process produces high-strength, fine yarn with good elasticity and smoothness. It is widely used for various types of textiles but can result in yarn with more
hairiness compared to advanced methods.
2. Compact Spinning:
Compact spinning is an enhanced version of ring spinning. In this process, fibers are compacted and aligned more closely before twisting, resulting in yarn with reduced hairiness, higher strength, and improved evenness. This technique helps in producing smoother yarns that are suitable for high-quality
fabrics.
3. Siro Spinning:
Siro spinning involves spinning two rovings simultaneously and twisting them together to form a single yarn. This process enhances yarn strength and reduces pilling, while still maintaining softness. Siro-spun yarns are commonly used in woven fabrics and are known for their superior appearance and
performance.
4. Compact Siro Spinning:
Compact siro spinning combines the benefits of both compact spinning and siro spinning. In thismethod, the fibers are first compacted and then spun as siro yarns. This results in yarn with minimal hairiness, high strength, and better smoothness, making it ideal for premium-quality textiles that require
excellent fabric properties and durability.
