Liyuan Fiber briefly describes the eight characteristics of textile fibers

1. Wear fastness

      Abrasion fastness refers to the ability to resist wearing friction, which contributes to the durability of fabrics. Garments made from fibers with high breaking strength and good abrasion fastness can last for a long time and show no signs of wear after a long period of time. Nylon is widely used in sports jackets, such as ski jackets, football shirts. This is because its strength and abrasion fastness are exceptionally good. Acetate is often used in the lining of outerwear and jackets due to its good drape and low cost. However, due to the poor abrasion resistance of acetate, the lining tends to fray or form holes before the outer fabric of the jacket wears accordingly.

2. Water absorption

      Water absorption is the ability to absorb moisture, which is usually expressed by moisture regain. The water absorption of fibers refers to the percentage of moisture absorbed by dry fibers in air at standard conditions of 70°F (equivalent to 21°C) and 65 percent relative humidity.

The water absorption of fibers affects many aspects of their applications, including:

Skin Comfort: Due to poor water absorption, the flow of sweat can cause a cold and wet feeling.

Static electricity: Clothing sticking and sparking problems can occur with hydrophobic fibers because there is little moisture to help disperse charged particles that accumulate on the surface of the fibers, and dust is also drawn to the fibers and adheres to them due to static electricity.

Dimensional stability after washing: After washing, hydrophobic fibers shrink less than hydrophilic fibers, and fibers rarely swell, which is one of the reasons for fabric shrinkage.

Stain Release: It is easy to remove stains from hydrophilic fibers because the fibers absorb the detergent and water at the same time.

Water repellency: Hydrophilic fibers usually require more water repellency and durable post-treatment, as this chemical treatment can make these fibers more water repellent.

Wrinkle Recovery: Hydrophobic fibers generally have better wrinkle recovery, especially after laundering, because they do not absorb water, swell, and dry in a wrinkled state.

3. Chemical effect

      Fibers typically come into contact with chemicals during textile processing (eg, dyeing, finishing) and home/professional care or cleaning (eg, with soap, bleach, dry cleaning solvents, etc.). The type of chemical, the intensity of action and the duration of action determine the degree of effect on the fiber. It is important to understand the effect of chemicals on different fibers as it directly relates to the care required in cleaning. Fibers react differently to chemicals. For example, cotton fibers are relatively low in acid resistance, while alkali resistance is very good. In addition, cotton fabrics will lose a little strength after chemical resin non-iron finishing.

4. Coverage

      Coverage refers to the ability to fill a range. Coarse or crimped fibers provide better coverage than fine, straight fibers. The fabrics are warm, feel full and require fewer fibers to weave. Wool is a widely used fiber in winter clothing because its crimp provides excellent coverage to the fabric and creates a large amount of still air in the fabric, which insulates against the cold outside. The effectiveness of fiber covering depends on its cross-sectional shape, longitudinal configuration and weight.

5. Elasticity

      Elasticity refers to the ability to increase in length under tension (elongation) and return to a rocky state (recovery) after the release of an external force. Elongation when an external force acts on the fiber or fabric can make the garment feel more comfortable and cause less stress on the seam. There is also a tendency to increase the breaking strength. Complete recovery can help prevent fabric sagging at elbows or knees, thereby preventing loose deformation of the garment. Fibers that can stretch at least 100 percent are called elastic fibers. Spandex fiber (Spandex is also called Lycra, our country is called spandex) and rubber fiber belong to this type of fiber. After elongation, these elastic fibers can almost forcefully return to their original length.

6. Environmental conditions

       Environmental conditions affect fibers differently. How fibers and fabrics respond to exposure, storage, etc. is very important. for example:

①Wool garments need to be protected from moths during storage, because they are easily eaten by wool moths.

②Nylon and silk are exposed to sunlight for a long time, and their strength will decrease, so they are usually not used to make curtains and doors and windows.

③ Cotton fiber is easy to mold, so it cannot be stored in a humid environment for a long time.

7. Flammability

      Flammability refers to the ability of an object to ignite or burn. This is an important feature because people's lives are always surrounded by a variety of textiles. We know that clothing or interior furniture, due to its flammability, can cause serious injury to consumers and cause significant material damage.

Fibers are generally classified as flammable, non-flammable, and flame-retardant.

① Flammable fibers refer to fibers that are easily ignited and will continue to burn.

② Non-flammable fibers refer to fibers with relatively high burning point and slow burning speed, which will self-extinguish after evacuating the burning source.

③ Flame retardant fibers refer to fibers that will not be burned.

     Flammable fibers can be made into flame-retardant fibers by finishing or changing fiber parameters. For example, regular polyester is flammable, but Trevira polyester is treated to be flame-retardant.

8. Softness

       Softness refers to the ability of fibers to bend repeatedly without breaking. Soft fibers such as acetate can support fabrics and garments with good drape. Rigid fibers such as glass fibers cannot be used to make clothing, but can be used in decorative fabrics that need to be relatively stiff. Generally, the finer the fibers, the better the drapability. Softness also affects the feel of the fabric.
