Textile fiber linear density and length composite fabric information

The linear density of fiber refers to the thickness of the fiber. Fiber length refers to the length of the fiber.
Textile fibers must have a certain linear density and length so that the fibers can cohere with each other and be spun into yarn relying on the friction between the fibers. Therefore, textile fibers have a certain linear density and length, which is one of the necessary conditions for textile processing and making the product valuable.
The linear density of textile fibers is closely related to the properties of textile processing and made yarns and fabrics. Generally speaking, lower fiber linear density and better uniformity are beneficial to textile processing and product quality. Among the effects of fiber linear density on the wearing properties of fabrics, fabrics made of finer fibers are softer and have a softer luster. Finer fibers can be used to produce lighter and thinner fabrics, and can also produce good breathability and silk-like effects. Good clothing fabrics. However, fabrics made of fine fibers are prone to fluffing and pilling, while fabrics made of coarse fibers can be made into stiff, rough and thick fabrics.
Similarly, the length of textile fibers is also closely related to textile and product quality. Longer fiber length, good length uniformity and less short fiber content are beneficial to textile processing and product quality. Under the same conditions, if the fiber is longer, the yarn will have high strength, even evenness, and the surface of the yarn will be smooth. The fabric will have good fastness, smooth appearance, and will not be prone to fluffing or pilling. In addition, under the premise of ensuring a certain yarn quality, the longer the fiber, the finer the yarn that can be spun, which can be used to make thinner fabrics. For short lengths, length is more important than linear density. For example, in the grade and pricing of cotton, length is the most important indicator.
Among textile fibers, the linear density and length of natural fibers are not uniform, and sometimes the differences are large. They vary with fiber varieties, growth conditions, etc. Chemical fibers are artificially manufactured, and the linear density and length of the fibers can be artificially controlled and determined within a certain range according to the requirements of fiber processing and use.
