Is polyester fiber a chemical fiber?

Question 1: What exactly is polyester fiber? Chemical fiber? Polyester fiber is a synthetic fiber spun from polyester condensed by organic diacid and diol. Polyester fiber produced in large quantities in industry is made of polyethylene terephthalate, and the trade name of China is polyester. It is the largest variety of synthetic fibers at present.

Question 2: What is polyester fiber? Is it chemical fiber? It is what we often say about polyester fabric. Polyester fiber is a synthetic fiber spun from polyester condensed by organic diacid and diol. China's trade name is polyester, which is the largest synthetic fiber variety at present.

Question 3: Is the fabric of clothes 100% polyester fiber, or is it chemical fiber? To be precise, it is chemical fiber, that is, polyester, which used to be-polyester.

Question 4: Is polyester fiber polyester? From an academic point of view, polyester is only one kind of polyester fiber, but from the perspective of idioms, polyester fiber refers to polyester, which can be translated into polyester and polyester fiber in foreign trade.

Question 5: Which is better, polyester fiber or superfine chemical fiber? Each has its own advantages, and the choice depends on the specific use and personal preference.

The following is a detailed introduction to both:

First, polyester fiber.

1, polyester fiber is a synthetic fiber spun from polyester condensed from organic dibasic acid and diol. Polyester fiber produced in large quantities in industry is made of polyethylene terephthalate, and the trade name of China is polyester. It is the largest variety of synthetic fibers at present.

2. The specific gravity of polyester is1.38; The melting point is 255 ~ 260℃, the bonding starts at 205℃, and the safe thinning temperature is135℃. The hygroscopicity is very low, only 0.4%; The breaking strength of filaments is 4.5-5.5g/ denier, and that of short fibers is 3.5-5.5g/ denier. The elongation at break of filament is 15 ~ 25%, and that of short fiber is 25 ~ 40%. The strength of high strength fiber can reach 7 ~ 8g/ denier and the elongation is 7.5 ~ 12.5%. Polyester has excellent wrinkle resistance, elasticity and dimensional stability, good electrical insulation, sunlight resistance, friction resistance, mildew resistance and moth resistance, good chemical resistance, weak acid and alkali resistance. At room temperature, it has a certain ability to resist dilute acid and strong alkali. The dyeing performance of polyester is poor, so it is generally necessary to dye it with disperse dyes at high temperature or in the presence of carriers.

3. Polyester has many excellent textile properties and wearability, and is widely used. It can be woven pure or blended with natural fibers such as cotton, wool, silk and hemp and other chemical fibers to make wool-like, cotton-like, silk-like and hemp-like fabrics with various colors, with good fastness, scratch resistance, easy washing and drying, washing resistance and wear resistance. Polyester fabric is suitable for men's and women's shirts, coats, children's clothes, interior decoration fabrics, carpets and so on. Because polyester has good elasticity and bulkiness, it can also be used as wadding cotton. In industry, high-strength polyester can be used as tire cord, conveyor belt, fire hose, cable, fishing net and so on. It can also be used as electrical insulation material, acid-resistant filter cloth and paper-making blanket. Polyester nonwoven fabric can be used for interior decoration, carpet backing, cloth for pharmaceutical industry, flocking, lining and so on.

Second, superfine fiber.

1, the definition of microfiber is different, and it is also called microfiber, fine denier fiber and microfiber. Generally, fibers with fineness less than 0.3 denier (5 microns in diameter) are called superfine fibers. Foreign countries have made 0.00009 denier superfine silk, and if such silk is pulled from the earth to the moon, its weight will not exceed 5 grams. China has been able to produce 0. 13-0.3 denier superfine fiber. The main components of superfine fiber are polyester and polyamide (in China, polyester accounts for 80%, polyamide accounts for 20% and polyester accounts for 100%).

2. Microfiber greatly reduces the stiffness of silk, and the fabric made is extremely soft to the touch. Fine fiber can also increase the layered structure of silk, increase the specific surface area and capillary effect, and make the reflected light inside the fiber distribute on the surface more finely, so that it has the elegant luster like silk and good moisture absorption and moisture dissipation performance. The clothing made of superfine fiber is comfortable, beautiful, warm, breathable, with good drape and fullness, and has obviously improved hydrophobicity and antifouling. Using the characteristics of large specific surface area and softness, we can design different tissue structures, absorb more sunlight heat energy or lose body temperature faster, and play the role of warming in winter and cooling in summer.

3. Microfiber has a wide range of uses: the fabric made of it, after advanced finishing such as sand washing and velvet grinding, forms a fluffy appearance similar to peach skin, which is extremely bulky, soft and smooth. High-end fashions, jackets, T-shirts, underwear and culottes made of this fabric are cool and comfortable, sweat-absorbent and not close to the skin, full of youthful beauty; High-grade artificial suede made of superfine fiber abroad not only has the appearance, feel and style similar to leather, but also has low price. Because the superfine fiber is thin and soft, the cleaning cloth made of it has excellent decontamination effect, and can wipe all kinds of glasses, film and television equipment and precision instruments without damaging the mirror surface. Microfiber can also be made into ultra-high density fabric with extremely smooth surface, which can be used to make sports clothes such as skiing, skating and swimming to reduce resistance and help athletes create good results. In addition, superfine fiber can also be used in filtration, medical care, labor protection and other fields.

Question 6: What is polyester fiber? What are the advantages and disadvantages of polyester fiber? Polyester fiber is a chemical fiber, better known as polyester fiber. Polyester fabric is a bit durable and wear-resistant. The disadvantage is that the traditional polyester fiber fabric has poor air permeability, but now some new modified polyester fibers, such as waterproof and moisture permeable fabrics, have solved this problem and are widely used in outdoor clothing and sportswear.

Question 7: Does polyester belong to chemical fiber cotton? Fibers can be divided into natural fibers and chemical fibers.

Natural fibers are divided into plant fibers and animal fibers.

There are many kinds of plant fibers: cotton, hemp, soybean and so on.

Animal fiber is divided into wool fiber, rabbit hair, camel hair and so on.

Chemical fiber: polyester, nylon, acrylic, polypropylene, etc.

Therefore, polyester belongs to chemical fiber, referred to as chemical fiber. Chemical fiber cotton is commonly known as cotton. As a filling material instead of cotton, it is breathable and washable, so it is called "chemical fiber cotton". The essence is chemical fiber.

I hope you can understand.

Question 8: Is the chemical fiber fabric polyester fiber fabric?

According to the different sources of raw materials, chemical fibers can be used.

It is divided into regenerated fibers and synthetic fibers.

Polyester is another synthetic fiber.

Polyester fabric has the advantages of easy scraping, easy washing and quick drying.

Polyester has better light resistance than nylon, and can resist microorganisms and mildew.

It is moth-proof, but its hygroscopicity is not as good as that of nylon, so it is not easy to dye.

Question 9: Are polyester and spandex both chemical fibers or fibers? 1. First of all, correct your concept: "fiber" refers to all kinds of natural fibers and chemical fibers.

As long as it is a textile raw material, it is all fiber, whether it is chemical, cotton or silk. People often refer to chemical fiber as "fiber" for short, which is very incorrect!

2, polyester, also known as polyester fiber, full name of polyethylene terephthalate, the most common and largest amount of synthetic fiber. Of course it belongs to chemical fiber.

3. Spandex, also known as polyurethane, is a highly elastic synthetic fiber, which is usually called Lycra in business. In fact, Lycra is just a brand of spandex.

Question 10: What's the difference between polyester and chemical fiber? Polyester is a chemical fiber.

Polyester is an important variety of synthetic fiber and the trade name of polyester fiber. It is a fiber-forming polymer-Polyethylene Terephthalate (PET) which is made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification, transesterification and polycondensation, and then spinning and post-treatment.

Chemical fiber is a kind of fiber with textile properties, which is made of natural polymer compounds or synthetic polymer compounds through the processes of preparing spinning dope, spinning and post-treatment.

With regard to the commodity names of chemical fibers, China has temporarily stipulated that synthetic staple fibers should be called "nylon" (such as nylon and polyester), cellulose staple fibers should be called "fiber" (such as viscose fiber and cuprammonia fiber), and the word "silk" should be added at the end of filament fibers, or "nylon" and "fiber" should be changed to "silk".
