1, cotton: cotton fiber is the cotton seeds covered with fibers, referred to as cotton. In addition to the cotton seeds of cotton fiber is called lint cotton or raw cotton.

Species: According to the thickness, length and strength of the fiber, the original cotton can generally be divided into three types of long-staple cotton, fine lint cotton and coarse lint cotton.

Structure: cotton fibers are open at one end of the tubular body, deflated into a hollow band after maturation and drying. The main component of the cotton fiber wall is the polymerization degree

Very high cellulose, dry mature cotton fiber, the content of cellulose in more than 95%, is nature's cellulose resources of the highest purity.

Performance: cotton fibers are generally fine and soft, more comfortable to the touch of the skin. It has a strong ability to absorb moisture. In general, the wet strength of cotton fiber

is greater than the dry strength. Elasticity is poor, the cellulose can be wrinkle-proof finishing to make it have a better shape retention. Cotton fiber has better warmth retention. High temperature

When the plasticity is better. Cotton fibers such as prolonged contact with sunlight, the strength is reduced, the fiber will become hard and brittle: if encountered with oxidizing agents, bleaching

Powder or oxidizing properties of dyes, fiber strength will also decline, and become brittle and hard.

2, hemp: hemp fiber is the first human clothing textile raw materials.

Species: Ramie and flax

Structure: The chemical composition of ramie fiber is generally 65% to 75% cellulose. After degumming, the fiber is white and lustrous and good fiber, called fine dry hemp.

In Japan, it is also called ramie fabric as silk linen fabric. Linen cellulose accounted for 70% to 80%.

Performance: hemp fabric feel stiff, crease recovery is very poor, wear poor; poor heat resistance, washing resistance; moisture absorption and moisture release, good breathability dyeing poor.

3、Wool

Species: cotton wool --- in the textile wool in the narrow sense often refers exclusively to cotton wool. Cashmere --- also known as cashmere, is a valuable textile raw material.

Structure: Wool fiber is a protein fiber, mainly consisting of a scale layer, a cortical layer and a medullary layer.

Performance: Wool fiber has poor strength, but good elasticity, woolen fabrics are stiff, not easy to wrinkle, and malleable. Wool fiber has better warmth than other fibers.

Wool fiber has better warmth than other fibers, better moisture absorption and breathability. Acid resistance is good, alkali resistance is poor, and the sunlight time should not be too long. But easy to insects and mildew.

4, silk: silk fiber is the only natural fiber in the long fiber.

Species: mulberry silkworm, Quercus sericea, castor silkworm, cassava silkworm, etc., with the best quality mulberry silkworm.

Structure: Silk consists of silk and silk glue.

Performance: Mulberry silk - good moisture absorption, water resistance, poor water permeability, light resistance and heat resistance. Quercus sericea silk---poor dyeability, easy to produce water stains.

Double-gong silk --- poor luster, thick fabric, distinctive style. Silk --- with waste silk and
