1. Definition and principles of combed cotton and carded cotton
Combed cotton and carded cotton are different names for the way cotton is processed. Before processing, combed cotton and carded cotton undergo different cotton purification and treatment processes, and the quality and performance of the final yarn produced are also different.
Specifically, combed cotton refers to repeatedly combing raw cotton to remove shorter and finer cotton fibers and retain longer and finer cotton fibers. Compared with combed cotton, the process of carded cotton is simple. It only needs one carding to mix cotton wool with similar length and thickness. It is stretched and humidified before spinning to produce a certain stretch and Tearing effect to obtain more uniform cotton yarn.
2. The difference between combed cotton and carded cotton
1. Fiber length: The fiber length of combed cotton is relatively long, while the fiber length of carded cotton is relatively short.
2. Fiber strength: The fiber strength of combed cotton is relatively high, while that of carded cotton is relatively low.
3. Fiber fineness: The fiber fineness of combed cotton is relatively fine, while the fiber fineness of carded cotton is relatively coarse.
4. Cost: Since combed cotton fiber is relatively high-quality, its processing cost is higher.
3. Advantages and disadvantages of combed cotton and carded cotton
Combed cotton has the characteristics of long fiber length, high strength and excellent quality. It can produce high-quality cotton yarn and fabrics and is suitable for high-end textile and knitwear production. However, its processing cost is high and the price is also expensive.
Carded cotton has a simpler process and lower cost. The yarn it produces is suitable for general cotton spinning and knitwear production, and the price of the finished product is relatively affordable. However, its fiber length and quality are relatively inferior to combed cotton, and its applicable range is relatively narrow.
Generally speaking, combed cotton and carded cotton each have their own advantages and disadvantages, and specific applications need to be selected based on production needs and cost control.
