What kind of fabric is chemical fiber fabric? Chemical fiber fabrics are everywhere in our daily life. In our life, the mention of chemical fiber fabrics often gives people a low-grade feeling. The performance of rayon fabric is mainly determined by the characteristics of viscose fiber. Let's take a look at what chemical fiber fabric is first.

What is chemical fiber fabric1i. What is chemical fiber fabric?

Chemical fiber fabric is a fabric made of pure chemical fibers, which is spun, blended or interwoven. Fabrics blended or interwoven with natural fibers do not belong to chemical fiber fabrics. There are many kinds, mainly tiger kapok, strong rayon, polyester, nylon, acrylic, polyvinyl chloride, vinylon, spandex and so on.

Second, the characteristics of chemical fiber fabrics

1, strong and durable, because chemical fiber fabric is a polymer fabric, so the fabric has high density and strong fastness, which is what people often say is strong.

2, easy to handle, wrinkle-resistant and non-ironing. Even if the chemical fiber fabric is kneaded into a ball, there are few or no wrinkles after opening.

3, the production cost is low, the industrial batch production can be carried out, and the price of raw materials is lower than that of natural fibers.

4, simulation, imitating natural fibers, with good hygroscopicity and comfort, even more comfortable than some natural fibers.

5, more personality, modern textile processing technology, so that chemical fiber fabrics have flame retardant, high temperature resistance, radiation protection, wear resistance, high elasticity, antibacterial and other unique personality.

Third, the classification of chemical fiber fabrics

Chemical fiber fabrics can be divided into regenerated fibers and synthetic fibers according to different sources of raw materials.

1. Regenerated fibers can be divided into regenerated cellulose fibers and rich and strong silk fibers, commonly known as tiger kapok and strong rayon.

2. Common synthetic fibers are polyester, nylon, acrylic fiber, polyvinyl chloride, vinylon and spandex.

What is chemical fiber fabric? Is chemical fiber fabric harmful to human body?

Is chemical fiber fabric harmful to human body? Chemical fiber fabrics have the following hazards to human body:

1, often wearing chemical fiber fabric is not good for your health. People used to wear cotton clothes. Later, chemical fiber fabrics entered the market, and many people wore chemical fiber clothes. Later, they felt uncomfortable wearing chemical fiber clothes. Now some people are wearing cotton again.

2. Chemical fiber fabrics are cheap and wear-resistant. Some people wear clothes made of chemical fiber fabric too often. They don't know that chemical fiber clothing has many pathogenic factors compared with cotton, hemp, silk and wool, which is not good for human health.

3. Chemical fiber fabric has a strong electrostatic effect, which can induce functional arrhythmia-ventricular premature beats for some people. If you take off your chemical fiber clothes, premature beats will decrease and disappear. The reason is that the static electricity generated by the contact between the chemical fiber underwear and the body surface changes the biological potential of the human body, interferes with the normal cardiac electrical conduction and leads to arrhythmia.

4. There are more than 8,000 kinds of additives in the manufacturing process of chemical fiber fabrics, such as bleach and softener. If you wear underwear with chemical fiber fabric, the chemical fiber substances on the fabric are easily absorbed by the human body. After a long time, it will produce cumulative irritation, causing eczema, contact dermatitis, atopic dermatitis, urticaria and so on.

A survey in Japan found that the increase of female cystitis was mainly due to wearing chemical fiber underwear. Some young women's underwear, underwear, trousers and tops are all made of chemical fiber, which is very easy to cause bacteria to grow and multiply at the urethral orifice, thus causing cystitis.

6, the elderly wearing chemical fiber clothes is easy to induce and aggravate the elderly skin itching. Because of the atrophy of sebaceous glands and sweat glands in the elderly, the secretion of sebum and sweat glands is reduced, the skin is dry and peeling, and the immune function is reduced. If you wear chemical fiber for a long time due to electrostatic stimulation, it can induce itching of the chest, back and limbs.

Advantages and disadvantages of chemical fiber fabric

Advantages of chemical fiber fabric:

1, comfortable

Chemical fiber has three advantages in the early stage of development: first, it is solid and practical; Second, it is easy to take care of and has the characteristics of anti-wrinkle and non-ironing; Third, it can be industrialized and produced on a large scale, unlike natural fibers, which occupy land, processing is time-consuming and laborious, and the output is limited.

2. Functionality

As an artificial polymer, chemical fiber can be pre-planned in the production process. For example, adding antibacterial agent to make it have antibacterial function; Mineral micropowder is added to make it have low radiation function or far infrared radiation function. This is obviously simpler, more economical and more effective than transforming natural fibers.

3. Highly rational

For the change of Japanese textile consumption market, differentiated fiber is called high-rational fiber, which is actually a series of chemical fibers with outstanding advantages in some parts, and then through modern textile processing technology, the functions of different chemical fibers are complemented by each other to produce textiles with many inductive functions beyond natural fibers.

Disadvantages of chemical fiber fabrics:

1, chemical fiber fabrics have poor wear resistance, heat resistance, hygroscopicity and air permeability, and are easy to deform and generate static electricity when heated, which is harmful to human body after long-term use.

2. The chemical fiber fabric has poor adsorbability and can't "adsorb" silk well. Because silk can't be integrated with the tire cover, it will shrink into a ball after being used for a period of time, which will affect the use effect.

What is chemical fiber fabric? 3 What are the chemical fiber fabrics?

First, rayon fabric.

Characteristics of rayon fabric

Rayon fabrics basically refer to viscose filament and staple fiber fabrics, commonly known as rayon and rayon. In addition, it also includes some fiber-rich fabrics and medium-long fiber fabrics between filaments and short fibers. Therefore, the performance of rayon fabric is mainly determined by the characteristics of viscose fiber.

1. rayon and rayon fabrics are soft to the touch, breathable, comfortable to wear and brightly dyed.

2. Rayon fabric has good hygroscopicity, which is the best in chemical fiber. However, its wet strength is very low, only about 50% of the dry strength, and the shrinkage rate of the fabric is large, so it is best to shrink in advance before cutting.

3. Ordinary viscose fabric has the characteristics of good drape, poor rigidity, poor resilience and poor wrinkle resistance, so its clothing has poor shape retention and is easy to wrinkle.

4. Viscose fiber fabric has good acid and alkali resistance, sunlight resistance and other drug resistance.

In a word, man-made fiber fabrics are superior to other chemical fiber fabrics because of their excellent hygroscopicity. However, due to the fact that their fabrics will become hard after entering the water, their strength will become worse, so be careful not to rub hard when washing. In addition, when cutting, the hem should be left wider and the edge should be trimmed to avoid yarn slippage and "tripping".

Second, polyester fabrics

Characteristics of polyester fiber fabric

Polyester fabric is a kind of chemical fiber clothing fabric widely used in daily life. Its biggest advantage is good wrinkle resistance and shape retention, and it is suitable for making outerwear clothing. Generally speaking, polyester fabrics have the following characteristics:

1. Polyester fabric has high strength and elastic recovery. So durable, wrinkle-resistant, non-ironing.

2. Polyester fabric has poor hygroscopicity, feels sultry when wearing, and is easy to carry static electricity and dust, which affects beauty and comfort. However, it is very easy to dry after washing, and the wet strength hardly decreases, and it does not deform, so it has good washing resistance and wear resistance.

3. Polyester is the fabric with the best heat resistance among synthetic fabrics, which is thermoplastic and can be made into pleated skirts with lasting pleats. At the same time, the polyester fabric has poor melting resistance, and it is easy to form holes when encountering soot and Mars. Therefore, contact with cigarette butts and sparks should be avoided when wearing.

4. The light fastness of polyester fabric is better than that of acrylic fiber, and its light fastness is better than that of natural fiber fabric. Especially behind the glass, the sun resistance is very good, almost equal to acrylic fiber.

5. Polyester fabric has good resistance to various chemicals. Acid and alkali do little damage to it, and it is not afraid of mold and moths.

Third, nylon fabric.

Characteristics of nylon fiber fabric

Nylon fabric is famous for its excellent wear resistance. It is not only the best choice for down jackets and mountaineering clothes, but also often blended or interwoven with other fibers to improve the strength and fastness of fabrics. The characteristics of nylon fiber fabric can be summarized as follows:

1. The abrasion resistance of nylon fabric ranks first among all kinds of fabrics, which is many times higher than other fiber fabrics of similar products, so it has excellent durability.

2. The hygroscopicity of nylon fabric is a good variety in synthetic fiber fabric, so the clothing made of nylon is more comfortable than polyester clothing.

3. Nylon fabric is a kind of light fabric, which is second only to polypropylene fabric and acrylic fabric in synthetic fiber fabric, and is suitable for making mountaineering clothes and winter clothes.

4. Nylon fabric has excellent elasticity and elastic recovery, but it is easy to deform under a small external force, so its fabric is easy to wrinkle during wearing.

5. Nylon fabric has poor heat resistance and light resistance, so attention should be paid to washing and maintenance conditions when wearing it to avoid damaging the fabric.

Four. Acrylic fabric

Acrylic fabric, commonly known as artificial wool, has a soft and fluffy feeling similar to wool fabric and bright color, which is deeply loved by consumers.

Acrylic fiber fabric is characterized by:

Acrylic fiber has the reputation of synthetic wool, and its elasticity and bulkiness are similar to those of natural wool. Therefore, the warmth retention of its fabric is not lower than that of wool fabric, and even higher than that of similar wool fabric by about 15%.

2. Acrylic fabrics are brightly dyed, and the light resistance is the first among all kinds of fiber fabrics. But its wear resistance is the worst among all kinds of synthetic fiber fabrics. Therefore, acrylic fabric is suitable for outdoor clothing, swimwear and children's wear.

3. Acrylic fabric is poor in hygroscopicity, easy to stain and sultry to wear, but good in dimensional stability.

4. Acrylic fabric has good heat resistance, ranking second among synthetic fibers, acid resistance, oxidant resistance, organic solvent resistance and relative sensitivity to alkali.

5. Acrylic fabric is a lightweight fabric among synthetic fiber fabrics, second only to polypropylene, so it is a good lightweight clothing material, such as mountaineering clothes and winter warm clothes.

Chemical fiber fabrics are mainly divided into two categories, one is recycled fiber fabrics, and the other is synthetic fiber fabrics. Regenerated fiber fabrics are generally made of some polymers and high proteins through chemical processing, and synthetic fabrics are generally made of some polyester materials. Generally, recycled fiber fabrics are more expensive and breathable. Synthetic fiber fabrics have poor air permeability and water absorption, and the price is relatively cheap.
