the 13 features of fiber


Water imbibition

The absorbency of a fiber is the ability to absorb moisture, which is usually expressed by moisture regain. Moisture regain is the index of moisture absorption of textile materials. Standard moisture regain refers to fiber in standard atmospheric temperature 20 ℃, relative humidity (65%), put wet absorption effect to balance the steady state, fiber wet weight percentage of fiber dry weight.

The fibers that absorb water are called hydrophilic fibers, such as viscose and acetate.


Chemical resistance

In the process of textile processing (such as printing and dyeing, finishing) and family/professional care or clarity (such as using soap, bleaching powder and dry cleaning solvent, etc.), the fibers generally need to be exposed to chemicals. The type, intensity and duration of the chemicals determine the degree of influence on the fibers. It is important to understand the effects of chemicals on different fibers, because it is directly related to the care needed in cleaning.


The elastic

Resilience refers to the ability to increase the length (elongation) and to recover to the rock state (recovery) after the pull. The elongation of an external force on a fabric or fabric makes the garment feel more comfortable, and the joints are less stressed. There is also a tendency to increase fracture strength. A complete response can help to prevent the garment from flaccid by allowing it to be produced on the elbow or knee.

At least 100 percent of the fiber is called elastic fiber. Spandex and rubber fiber belong to this kind of fiber. After the elongation, these elastic fibers can be almost powerfully restored to their original length.



Flammability is the ability of an object to ignite or burn. This is a very important feature, because people's lives are always surrounded by a variety of textiles. Clothing or indoor furniture, because of its flammability, can cause serious injury to consumers and cause significant material loss.

Flammable fiber can be made by finishing or changing the fiber parameters to make flame retardant fiber. For example, conventional dacron is flammable, but Trevira humidified fibers are treated with flame retardant.



Softness refers to the ability of the fiber to repeatedly bend without breaking, and the softness affects the feel of the fabric. The thinner the fiber, the better the drape.

For example, acetate fiber can be made into overhanging fabric and clothing because of its superior softness. Although it is often required that the drape of the fabric is good, it sometimes requires a relatively stiff fabric. For example, in a garment with a cape (which hangs over the shoulder and turns out), use a stiffer fabric to achieve the desired shape.



Touch is the feeling of touching a fiber, yarn, or fabric. The hand of a fiber feels its shape, surface characteristics and structure. The shape of the fiber is different, there are round, flat shape, multi - leaf shape, etc. The fibers also have different surfaces, such as smooth, serrated, or scaly. The shape of the fibers is not curly or straight.

In addition, the yarn type, fabric structure and finishing process can also affect the feel of the fabric. Soft, smooth, dry, pure silk, hard, rough or rough, etc., to describe the feel of the fabric.



Gloss refers to the reflection of light on the surface of a fiber. The different properties of the fibers affect their glossiness. Shiny surfaces, less curved, flat section shapes and longer fiber lengths can enhance the reflection of light. The drafting process in the fiber manufacturing process increases its luster by making its surface smoother. The addition of a delustering agent will destroy the reflection of the light and reduce the luster. In this way, the amount of absorbent can be controlled, and optical fiber can be manufactured, and the fiber with optical fiber will be reduced.

Fabric luster is also affected by yarn type, organization and all finishing. The gloss requirements will depend on trends and customer needs.


The ball

Pilling refers to the short, broken fibres on the surface of the fabric that intertwine with each other. When the end of the fiber breaks from the fabric's surface, the ball is formed, usually by wearing. The ball is produced in areas of constant friction, such as the collar, the lower part of the sleeve and the edge of the cuff.

Hydrophobic fibers are more prone to pilling than hydrophilic fibers, because hydrophobic fibers are more likely to attract static electricity to each other and are less likely to fall off the surface of the fabric.



Resilience is the ability of a material to respond flexibly after it is folded, twisted and twisted. It is closely related to wrinkle recovery ability. The fabric with good resilience does not wrinkle easily, so it is easy to maintain a good shape.

The coarser fibers have a better resilience because they have greater mass to absorb strain. At the same time, the shape of the fiber also affects the elasticity of the fibers, and the circular fibers have better resilience than flat fibers.


Relative density

Relative density refers to the fiber quality and equal volume 4 ℃ when the ratio of the water quality. Light fibers can keep the fabric warm and unwieldy, which can be thick and fluffy, but it can still hold a lighter weight. Acrylic fiber is one of the best examples, it is much lighter than wool, but has properties similar to wool, which is widely used in fabric is light and warm winter thick blankets, scarves, socks, and other supplies.



Static electricity is the electric charge generated by the friction between two different materials. When the charge is generated and accumulates on the surface of the fabric, it will be attached to the wearer's body or cotton wool to attach to the fabric. When the surface of the fabric is in contact with the foreign body, a spark or electric shock is produced, which is a rapid discharge process.

The water contained in the fiber ACTS as a conductor to remove the charge and prevents the aforementioned electrostatic effects. Because of the danger of static electricity in a special working environment, it is very important to use low electrostatic fiber products, which is often used in the vicinity of flammable liquids or gases such as hospitals and gas stations.


The intensity of

Strength is the fiber's ability to resist stress. The strength of the fiber is the force required to break the fibre, expressed in the kili/denier or centibull/Tex (legal unit of measurement).


Core role in absorption

The core suction is the ability of the fibers to transfer water from one place to another. Usually, water is passed along the surface of the fibers, but when the liquid is absorbed by the fibers, it can also pass through the fibers. Fiber core absorption tends to depend on the chemical and physical composition of the surface. The smooth surface will reduce the core absorption.
