What is the difference between brocade, polyester and ammonia?

a) What is Polyester?

Polyester is an important variety of synthetic fibers and is the trade name of polyester fiber in China. It is a fiber-forming polymer - polyethylene terephthalate (PET), which is prepared by esterification or transesterification and polycondensation reaction of purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) as raw materials, and is made of fiber after spinning and post-treatment.

2) What are the properties of polyester?

1. High strength. The strength of short fibers is , and the strength of high strength fibers is . Due to its lower moisture absorption, its wet strength is basically the same as that of dry state. The impact strength is 4 times higher than that of nylon and 20 times higher than that of viscose.

2. Good elasticity. The elasticity is close to that of wool and when elongated by 5% to 6%, it can be almost completely recovered. The wrinkle resistance exceeds that of other fibers, that is, the fabric does not wrinkle and has good dimensional stability. The elastic modulus is 22 141cn dtex, which is 2 3 times higher than that of nylon.

3. Good heat resistance.

4. Good water absorption.

5. Good wear resistance. The abrasion resistance is second only to nylon, which has the best abrasion resistance, and is better than other natural fibers and synthetic fibers.

6. Good lightfastness. Lightfastness is second only to acrylic. 7. Corrosion resistance. Resistant to bleach, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids. It is resistant to dilute alkali and is not afraid of mildew, but hot alkali can decompose it.

8. Poor staining.

3) What are the major categories of polyester?

The major varieties of polyester include staple fiber, drawn yarn, textured yarn, decorative filament, industrial filament and various differentiated fibers.

4) What are the varieties of polyester staple fiber?

1.According to physical properties: high-strength and low-elongation type, medium-strength medium-elongation type, low-strength medium-extension type, high-strength and medium-extension type, high-strength and high-modulus type.

2.According to the post-processing requirements: cotton type, wool type, hemp type, silk type.

3.According to the use: clothing, wadding, decoration, industrial.

4.Distinguish by function: cationic dyeable, hygroscopic, flame retardant, colored, anti-pilling, antistatic.

5.According to the fiber cross-section: special-shaped wire, hollow wire.

The cotton of spandex --- modified polypropylene fiber, but it is rarely called cotton fiber in daily life.

The wicking effect of cotton fiber makes it have excellent characteristics such as soft warmth, moisture conduction and dryness, hygiene and antibacterial. The ultra-cotton underwear, bathrobes, T-shirts and other products developed and produced with it have superior properties such as warmth, water absorption, moisture conduction, quick drying, and antibacterial.

Polypropylene fiber has the advantages of small specific gravity, non-water absorption, low thermal conductivity, good chemical resistance, and good hygiene. In this project, the fluidity of the melt can be effectively improved by adding additives to the polypropylene raw material, and the fine denier staple fiber is prepared after melt spinning. Due to the geometric characteristics, surface effect, gloss effect and mechanical properties of fine denierization, the fiber has changed the shortcomings of poor hand feel, wax feeling, poor moisture absorption, etc., and has a very soft feel, soft luster and excellent moisture absorption and sweat conductivity; Colored fibers can also be spun from masterbatches.

Polyester: close to flame - softened, melted and curled sail sensitive.

In the flames - melting, slow-burning, with yellow flames, blue flames, black smoke from the top of the flames.

Flame - continues to burn, sometimes stops burning and self-extinguishes.

Burning smell - slightly aromatic or sweet.

Residue characteristics - the ash is hard and black spherical, and it is not easy to crush with fingers.

Nylon: close to the fire state of the branch flame - combustible softening and shrinking.

In the flame - shrinking, melting, burning slowly, producing small bubbles, the flame is very small, and the flame is blue and blue - stops burning and self-extinguishes.

Burning smell - amino or celery.

Residue characteristics - the ash is hard and black spherical, and it is not easy to crush with fingers.

The clothing tag indicates the composition of the clothing fabric, as long as the clothing with these components is generally the clothes produced by the regular manufacturer or the fabric of the regular manufacturer. Spandex, polyester, and nylon are all man-made fibers. But the general situation is either purified fiber fabrics, or blended, for example, polyester cotton is the product of polyester and cotton blending, it can integrate the advantages of man-made fibers and cotton, to supplement their own shortcomings, so, blended fabrics are easier to take care of this reason!

Spandex is used to weave all kinds of underwear, swimsuits, tights, jeans, sportswear, elastic parts of belts, etc., clothing made of spandex is comfortable to wear, can adapt to the needs of deformation of various parts of the body, and can reduce the sense of restraint of clothing on the body. Nylon filament yarn is mainly used to make strong yarn for the production of socks, underwear, sweatshirts, etc. Nylon staple fiber is mainly blended with viscose, cotton, wool and other synthetic fibers for clothing fabrics.

Nylon can also be used industrially as tire cords, parachutes, fishing nets, ropes, conveyor belts, etc.

Then the proportion of ingredients they contain is different, and the characteristics of the woven fabric are not the same. So, when choosing clothes in the future, pay attention to the composition of the fabric, choose what you like, and wear comfortable clothes to buy!

Good luck with your outfit!

Spandex, taperein, and nylon are all material names for textiles, that is, the fabric of clothes is spun from these materials.

1. Spandex: Spandex is the abbreviation of polyurethane fiber, which is an elastic fiber, spandex is generally composed of multiple filaments, generally 10d, and now there are 15d, or even 20d.

2. Polyester: It is a fiber-forming polymer prepared by esterification or transesterification and polycondensation reaction of purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) as raw materials, polyethylene terephthalate (PET), which is a fiber made of spinning and post-treatment, polyester is an important variety of synthetic fibers.

Third, nylon: is the first synthetic fiber in the world, commonly known as nylon in Chinese. Commonly used nylon fibers can be divided into two main categories.

1. The first type is polyadipic acid hexamethylenediamine obtained by the polycondensation of diamine and diacid, and the chemical structure of its long-chain molecule is:

h—[hn(ch2)xnhco(ch2)yco]—oh。

2. The other type is obtained by caprolactam polycondensation or ring-opening polymerization, and the chemical structure of its long-chain molecule is:

h—[nh(ch2)xco]—oh。

Those refer to the composition of the garment, that is, what material the garment is made of and what the content is. To put it bluntly, these ammonia, silk and brocade are all chemical fibers that were originally said to be man-made materials, which are different from natural materials such as cotton, linen and silk.

The cotton content in nylon is relatively high, so the cost is more expensive, and the feel is closer than that of polyester, so it will be better to do clothing nylon, Xinxiang Yulong Textile specializes in the production of special tooling.

Nylon: warm, absorbent, moisture-conductive, quick-drying, antibacterial, soft, shiny, high-grade.

Polyester: heat-resistant, wear-resistant, water absorption, light-resistant, good color fastness, not easy to deform.

Viscose: breathable, cool, antistatic, smooth, not prone to wrinkles.

Linen: wear-resistant, absorbent, warm, breathable, rough.

Nylon is the Chinese name for polyamide fiber, and the translated name is also called "Nailon" or "Nylon". When it comes to what kind of fabric nylon is, we have to start from its characteristics.

First, the strength and wear resistance of nylon are good, ranking first among all fibers. This is one of the reasons why nylon is used as a raw material for mountaineering clothing and winter clothing. Clothes made of nylon are usually durable and resistant to wear and tear.

Second, the elasticity and elastic recovery of nylon fabric are excellent, but it is easy to deform under small external force, so nylon clothing is easy to wrinkle during wearing, which affects the appearance.

Third, the ventilation and permeability of nylon are poor, and it is easy to generate static electricity. Therefore, it is best not to wear underwear made of nylon to prevent harm to the human body.

Fourth, the hygroscopicity of nylon fabric is a better variety in synthetic fiber fabrics, so clothing made of nylon is more comfortable to wear than polyester clothing.

Fifth, nylon has good moth resistance and corrosion resistance, and is relatively easy to preserve.

Sixth, the heat and light resistance of nylon is not good enough, and the ironing temperature should be controlled below 140 degrees. During wearing and use, attention must be paid to the relevant conditions of washing and maintenance to avoid damage to the fabric.

Seventh, nylon fabric is a light fabric, second only to polypropylene and acrylic fabrics in synthetic fiber fabrics, so it is suitable for making mountaineering clothing, winter clothing, etc.

Personally, I don't think it's good, cotton and linen are better, and silk is also good.
