Seventeen characteristics of textile fibers

First,Abrasion -resistant

The wear resistance refers to the ability to resist wearing friction, which helps improve the durability of the fabric. Costumes made of fibers made of high -break strength and faith resistance can be worn for a long time, and there will be signs of wearing wear after a long period of time.

Nylon is widely used in sports jackets, such as ski jackets and football shirts. This is because its strength and wear resistance are particularly good. Because of its excellent hanging and low cost, paradise fiber is often used in the lining of coats and jackets.

However, due to the poor wear resistance of acetate fiber, it is easy to wear or form a hole in the lining or form a hole in the outer fabric of the jacket.

 

Second, Water absorption

Water absorption is the ability to absorb moisture, and it is usually represented by a recovery rate. The water absorption of the fiber refers to the percentage of water absorbing moisture in the air under the temperature of 70 ℉ (equivalent to 21 ° C) and a relative humidity at a temperature of 70 ℉ (equivalent to 21 ° C) and the relative humidity.

Easy -to -water fiber is called hydrophilic fiber. All natural animal and plant fibers and two artificial fibers -adhesive fiber and acetaceous fiber are hydrophilic fibers. Those fibers with difficulty absorption or absorbing a small amount of water are called hydrophobic fibers. Except for adhesive fiber, Lyocell fiber, and acetate fiber, all artificial fibers are hydrophobic fibers. Glass fiber does not absorb water at all, and other fibers usually have only 4%or lower tide.

The water absorption of fiber affects many aspects of its applications, including:

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

Static electricity: With the problem of hydrophobic fiber, clothes sticky and sparks are caused by the problem of giving up the tape particles accumulated on the fiber surface because there is almost no water to help evacuate the fiber.

Size stability after washing: After washing, hydrophobic fibers contracted smaller than hydrophilic fiber, and fiber rarely expands. This is one of the causes of fabric contraction.

Discovering: It is easy to remove stains from hydrophilic fibers, because fiber will inhale the detergent and water at the same time.

Water refusal: hydrophilic fiber usually needs to be treated more after durability, because this chemical treatment can make these fibers better water -rejectability.

Wrinkles: hydrophobic fiber usually has better fold recovery, especially after washing and scalding, because they do not absorb water, do not swell, and dry them in folds.

 

Third, Chemical effect

In the process of textile processing (such as printing and dyeing, post -sorting) and family/professional care or clear (such as soap, bleaching powder and dry cleaning solvents, etc.), fiber generally needs to be in contact with chemicals. The type, intensity and action time of chemicals determine the degree of impact on fiber. It is important to understand the impact of chemicals on different fibers, and it should be directly related to the care required in cleaning.

Fiber has different reactions to chemicals. For example, cotton fiber acid resistance is relatively low, while alkali resistance is good. In addition, cotton fabrics will lose a little strength after chemical resin is not sorted out.

 

Fourth, Coverage

Cover is the ability to fill a certain range. Textile coverage made of crude fiber or curling fiber is better than fine and straight fiber. Its fabric is warm, full of feel, and it only needs less fibers to be woven.

Wool is a widely used fiber in winter clothing, because its curling provides excellent coverage for fabrics, and a large amount of static air is formed in the fabric. These static air isolates from the external air -conditioning. The effectiveness of fiber coverage depends on its section shape, vertical structure and weight.

 

Five, Elasticity

Elasticity refers to the ability to increase the length (extended) and the external forces under the action of pulling force. When the extension of the external force on the fiber or fabric can make people feel more comfortable, and the seam stress caused by it is relatively small.

At the same time, there is also a tendency to increase the strength of the break. A complete response can help the elbow tube or knee fabric to be generated, thereby preventing the clothing from being relaxed and deforming. It can extend at least 100%of fiber called elastic fibers. Spandex (SPANDEX is also called Lycra, my country is called amino amino) and rubber fibers belongs to this type of fiber. After stretching, these elastic fibers can almost return to its original length.

 

six,Environmental Conditions

The impact of environmental conditions has different effects on fiber. Fibrous and final fabrics are very important to react to exposure and storage.

Here are some examples:

Wool clothing requires insects when storing, because they are easily invaded by wool worms.

Nylons and silk are exposed to the sun for a long time, and the intensity will decrease, so they are usually not used to make curtains and doors and windows.

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

 

Seven, Combustible

Fryality refers to the ability of an object to ignite or combustion. This is a very important feature, because people’s lives are always surrounded by various textiles. We know that clothing or indoor furniture will cause serious damage to consumers and cause major material losses to consumers.

Fiber is usually divided into flammable, non -flammable, and flame retardant:

Fiber of flammable fiber refers to fibers that are easily ignited and will continue to burn.

The non -flammable fiber refers to a relatively high combustion point, and the combustion speed is relatively slow. The fiber that will be extinguished by itself after evacuating the burning source will be extinguished by itself.

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

Flammable fibers can be made into flame retardant fibers by organizing or changing fiber parameters. For example, conventional polyester is flammable, but Trevira polyester has flame retardant after treatment.

 

Eight, Softness

Softness refers to the performance of fiber that is easy to repeat and cracking. Soft fibers such as paradiphylene fiber can support fabrics and clothing with good hanging. Rigid fibers such as glass fibers cannot be used for making clothing, but it can be used on the relatively hard fabrics for decoration. Usually the thinner fibers, the better the hanging. Softness also affects the feel of the fabric.

Although the fabric is often required to be good, sometimes it is necessary to be relatively stiff fabrics. For example, on a cloak (clothes hanging on your shoulders and turning out of the shoulder), use a harder fabric to achieve the required shape.

 

Nine, Feel

The feel is the feeling of touching fiber, yarn or fabric. Fiber’s hand feels its shape, surface characteristics, and structure. The fiber forms are different, and can be round, flat, polyaline, etc. The surface of the fiber is also different, such as smooth, jagged or scales.

The shape of the fiber is either curled or straight. The gauze type, fabric structure, and post -finishing process will also affect the feel of the fabric. It is commonly used to describe the feel of the fabric.

 

Ten, Gloss

Gloss refers to the reflection of the fiber facing light. Different characteristics of fibers affect its gloss. The surface of gloss, less curved, flat section shapes, and longer fiber length can enhance the reflection of light. The extension process in the process of fiber manufacturing increases its luster by smoother surface. Adding an anti -light agent will destroy the reflection of light and reduce the gloss. In this way, controlling the dosage of the adaptering agent can be manufactured with optical fiber, optical fiber and light -free fiber.

The fabric luster is also affected by the gauze type, tissue and all organizational. The requirements of gloss will depend on the trend and the needs of customers.

 

Eleven, Getting The Ball

The ball refers to some short and broken fibers on the surface of the fabric to form a small ball. When the end of the fiber is broken from the surface of the fabric, the velvet is formed, which is usually caused by wearing. The ball is not needed, because it makes fabrics such as sheets old and not beautiful, and it feels uncomfortable. The velvet balls are generated at the frequently rubbed parts, such as the collar, the lower part of the sleeve, and the edge of the cuffs.

Hydrophobic fibers are easier to get balls than hydrophilic fibers, because hydrophobic fibers are easier to attract static electricity with each other, and it is not easy to fall from the surface of the fabric. The velvet is rarely seen on a 100%cotton shirt, but it is very common on the similar shirts of polyester -cotton blended in polyester cotton in a period of time. Although wool is hydrophilic, the velvet is caused by its scale -like surface. Fiber twisted and wrapped with each other to form a velvet ball. The strong fiber is easy to hold the velvet ball on the surface of the fabric. Low -intensity fibers that are easy to break, because the velvet is easy to fall, it is not easy to get the ball.

 

Twelve, Return Elasticity

Return elasticity refers to the ability to respond elastic recovery after being folded, twisted, and twisted. It is closely related to fold recovery capabilities. The fabrics with better elastic fabrics are not easy to wrinkle, so it is easy to maintain its good shape.

The thicker fiber has better reflection, because it has large quality to absorb the strain. At the same time, the shape of the fiber also affects the fiber’s reflection, and the round fiber has better reflection than flat fibers.

The nature of fiber is also a factor. Polyester fibers have outstanding return of reflection, but the cotton fiber is poorly elastic. Therefore, these two fibers are often mixed in some products, such as men’s shirts, women’s loose tops and sheets, which is not surprising.

If you need to form obvious wrinkles on the clothing, the fiber that rebounds a good will be a bit troublesome. It is easy to form a crease on cotton fabrics or coarse glue fiber fabrics, but it is not easy to get on dry wool fabrics. Wool fiber is bent and folds, and can be straightened at the end.

 

Thirteen, Relative Density

Relative density refers to the ratio of water quality at 4 ° C of fiber quality. Light fiber can keep the fabric and not bulky, which may become thick and fluffy fabrics, but it can still maintain a lighter weight. Pyrene fiber is the best example. It is much lighter than wool, but it has a similar nature to wool, which is widely used in the fabric’s light and warm blankets, scarves, thick socks and other winter supplies.

 

Fourteen, Static Electricity

Static electricity is the charge generated by two different materials. When the charge is generated and accumulated on the surface of the fabric, it will be adsorbed on the fabric on the clothing of the clothing sticker or cotton velvet. When the surface of the fabric is in contact with the foreign body, an electric spark or electric shock will be generated, which is a rapid discharge process. When static electricity on the fiber surface is generated at the same speed of static electricity, the static electricity phenomenon can be eliminated.

Water containing in the fiber can eliminate the charge of the conductor and prevent the electrostatic effect mentioned earlier. Hydrophobic fiber, because it contains very little water, has a tendency to generate static electricity. Electricity is also produced in natural fibers, but it will only become like hydrophobic fibers when it is very dry. Glass fiber is an exception of hydrophobic fiber. Due to its chemical composition, static charge cannot be generated on its surface.

The fabric containing Ebit Robick fiber (fiber can conducts electricity) does not have the trouble of static electricity. The carbon or metal contained in it can make the fiber transfer the accumulated static charge. Because there is a static problem on the carpet, the Ultron Nylon is used on the carpet. Trobick fiber eliminates electric shocks, fabrics and dust adsorption. Due to the danger of static electricity in a special working environment, the use of low static fiber into a subway into a work area near the hospital and the computer is flammable, explosive liquid or gases near the area.

 

Fifteen, Strength

The strength is the ability to resist stress. The fiber strength is the force required for fibrous fiber.

 

Sixteen, Thermoplasticity

The ability of fiber heat resistance is an important factor affecting its application performance. Generally, this is also an important factor that needs to be considered in fiber treatment, because fibers need to be heated during the formation of many fabrics, such as dyeing, ironing and thermal type. In addition, heating is often used to care and update clothing and indoor furniture.

The impact of some heat is temporary and obvious in the process of action. For example, in dyeing, the nature of fiber can change during thermal effect, but after cooling, it returns to normal. However, the impact of some heat will be permanent, and the molecular arranges after the heat will cause fiber to degrade itself. The thermal type will change the molecular arrangement, making the fabric more stable (small shrinkage) and more anti -wrinkle, but there is no obvious degradation. However, extending time in high temperature may cause degradation, such as decreased strength, fiber contraction and discoloration. Many consumers have experienced severe degradation and even damaging clothing caused by high temperature ironing.

When heating, thermoplastic fiber becomes soft, and it can be melted into liquid when the temperature is higher. Many artificial fibers are thermoplasticity. By heating the heating of thermoplastic fibers to form a crease and folding but does not melt the fiber. When the temperature drops, it can be made into long -term creases and folds. When heating (softening), thermoplastic fiber can be molded. When cooling, the shape of the mold can be kept
(When ironing the clothing made of artificial fibers, be careful to avoid softening or melting. When softening or melting, the fabric will start to stick the iron)
The crease will be permanent, unless there is a higher temperature to eliminate the original hot -type effect. The shape of the clothing can also be formed through this method. Thermoplastic fabric has good size stability.

 

Seventeen. Core Absorption Effect

Core absorption refers to the ability to pass water from one place to another. Generally, water can be passed along the surface of the fiber, but when the liquid is absorbed by the fiber, it can also pass through the fiber. Fiber’s core suction tendency often depends on the chemical and physical composition of the outer surface. The smooth surface will reduce the effect of core suction.

Some fibers, such as cotton fiber, are hydrophilic fibers, and also have a good core absorption. Other fibers, such as olefin, are hydrophobic fibers, but when the number of Daniel is small (that is, a very fine fiber), it has a good core suction effect. This nature is particularly important for clothing such as training clothes and running. The sweat excreted from the human body is transferred from the core to the surface of the fiber surface to the outer surface of the clothing, and evaporates to the air, which brings better comfort.
