What are the characteristics of different knitted rib materials
1. Rib cotton: cotton fiber is the fiber covered on the cotton seed, referred to as cotton. The cotton fiber without cottonseed is called lint or raw cotton.
Variety: According to the fiber thickness, length and strength, raw cotton can be generally divided into three categories: long staple cotton, fine staple cotton and coarse staple cotton.
Structure: The cotton fiber is a tube with an opening at one end, which shrinks into a hollow ribbon after ripening and drying. The main component of cotton fiber wall is cellulose with high degree of polymerization. The content of cellulose in dry mature cotton fiber is more than 95%, which is a cellulose resource with high purity in nature.
Performance: The cotton fiber is generally thin and soft, and the skin feels comfortable. It has strong moisture absorption capacity. Generally, the wet strength of cotton fiber is stronger than the dry strength. Due to its poor elasticity, it can be used for anti wrinkle finishing of cellulose to make it have better shape retention. Cotton fiber has good thermal insulation. The plasticity is good at high temperature. If the cotton fiber is exposed to sunlight for a long time, its strength will be reduced, and the fiber will become hard and brittle; if it is exposed to oxidant, bleach or dye with oxidation performance, its strength will also be reduced, and the fiber will become brittle and hard.
2. Rib hemp: hemp fiber is the textile material used for clothing at first.
Variety: ramie and flax
Structure: The chemical composition of ramie fiber is generally 65%~75% cellulose. The degummed fiber is white and glossy, which is called refined flax. In Japan, it is also called ramie fabric as spun silk fabric. The cellulose of flax accounts for 70%~80%.
Performance: linen fabric feels firm; Poor heat resistance and water washing resistance; Good moisture absorption and desorption, good air permeability and poor dyeing.
3. Rib hair
Variety: cotton wool. In the narrow sense of textile, wool usually refers to cotton wool. Cashmere, also known as cashmere, is a kind of valuable knitting rib.
Structure: Wool fiber belongs to protein fiber, mainly composed of scale layer, cortex layer and medulla layer.
Performance: The strength of wool fiber is poor, but the elasticity is good. The wool fabric is neat, not easy to wrinkle, and has good plasticity. Wool fiber has better heat preservation, moisture absorption and air permeability than other fibers. Good acid resistance, poor alkali resistance, sunshine time should not be too long. But it is easy to be eaten and mildewed.
