Basic properties of textile fiber

1) Certain mechanical strength toughness

The fiber must be able to withstand certain pulling force, twisting, friction other external forces. fiber to clothing, there are many processes to process. Fiber - spinning into yarn thread - weaving into white grey cloth - scouring, bleaching, dyeing, finishing into clothing fabric - cutting, sewing, ironing into clothing - folding, packaging. In these processes, the fiber is subjected to repeated stretching, twisting, friction other external forces. If the fiber can bear these external forces, it will encounter difficulties in the spinning weaving process. The clothes are durable.

2) A certain fineness, length, can hold each other.

The fineness length of fiber are closely related to textile processing. The larger the ratio of general length to fineness, the easier to twist synthetic yarn, the better the quality of yarn, the better the weaving performance; the thinner the fiber, the thinner the fabric, the softer the hand; the longer the fiber, the cleaner the yarn, the smoother smoother the fabric.

3) Certain elasticity plasticity

Elasticity refers to the property of deformation under the action of external force, which can be restored to the original state after the removal of external force. Plasticity refers to the capability of being able to deform arbitrarily be fixed under humid hot conditions. These two properties refer to the properties that can be arbitrarily deformed fixed under humid hot conditions. These two properties are necessary in the process of fiber processing into yarn fabric sewing into clothing.

4) Must be a bad conductor of heat

One of the functions of clothing is to keep warm. Although clothing style, fabric structure, thickness yarn structure are related, but also depends on the thermal properties of fiber itself.

5) Certain moisture absorption permeability

Fiber hygroscopicity refers to the ability of fiber to absorb water vapor (water molecules) in the air, which is directly related to the molecular structure of fiber. The more hydrophilic groups there are in the fiber macromolecules, the stronger the polarity of the groups; the larger the arrangement space between the fiber molecules, the stronger the hygroscopicity; the hygroscopic property of the fiber is generally expressed by the moisture regain, which is the percentage of the moisture content of the fiber to its dry weight. The moisture content weight is the difference between the wet weight the dry weight of the fiber.

6) Certain chemical stability

The fabric made by fiber spinning needs to contact with many chemicals. After sewing into clothing, it will also contact with sweat fat carbon dioxide on the body. When washing, it will suffer the action of acid alkali solutions such as soap. All of these require the fiber to have relative chemical stability.

Countries have their own standards for the basic characteristics of textile fiber materials. Textile fibers that do meet the standards cannot be used as clothing fabrics.
