Polyester fabric features

Polyester fabric is a kind of chemical fiber fabric used in daily life. Its biggest advantage is that it has good wrinkle resistance and shape retention, so it is suitable for coat clothing. In general, polyester fabric has the following characteristics:
1. Polyester fabric has high strength and elastic recovery ability. Therefore, it is durable, wrinkle-free and non-iron.
2. Polyester fabric has poor hygroscopicity, and it has a stuffy feeling. It is easy to bring static electricity and stain dust, which affects the appearance and comfort. However, it is very easy to dry after washing, and the wet strength is hardly reduced, it is not deformed, and it has good washing and wearability.
3. Polyester is the best heat-resistant fabric in synthetic fabrics. It has thermoplastic properties and can be made into pleated skirts with long pleats. At the same time, the polyester fabric has poor resistance to melting, and it is easy to form holes in the case of soot or Mars. Therefore, wear should avoid contact with cigarette butts, sparks, etc.
4. Polyester fabric has better light resistance, and its lightfastness is better than natural fiber fabric except that it is worse than acrylic fiber. Especially in the back of the glass, the light fastness is very good, almost the same as acrylic fiber.
5. Polyester fabric has good performance against various chemicals. Acid and alkali have little damage to them, and they are not afraid of mold and are not afraid of insects.
Characteristics of nylon fiber fabric

Nylon fabric is known for its excellent wear resistance. It is not only the best choice for down jackets and mountaineering clothing, but is often blended or interwoven with other fibers to increase the strength and fastness of the fabric. The characteristics of nylon fiber fabrics can be summarized as follows:
1. The abrasion resistance of nylon fabric is the first of all kinds of fabrics, which is many times higher than other fabrics of similar products, so its durability is excellent.
2. The hygroscopicity of nylon fabrics is a good variety in synthetic fabrics, so garments made of nylon are more comfortable to wear than polyester garments.
3. Nylon fabric is a light fabric, which is only listed in polypropylene fabric and acrylic fabric in synthetic fiber fabric. Therefore, it is suitable for making mountaineering clothes and winter clothing.
4. The elastic and elastic recovery of nylon fabric is excellent, but it is easy to deform under small external force, so the fabric is easy to wrinkle during wearing.
5. Nylon fabrics are poor in heat resistance and light resistance. Care should be taken during washing and maintenance to avoid damage to the fabric.
The difference between nylon and polyester: high strength, good impact resistance, heat resistance, corrosion resistance, stagnation resistance, acid resistance and alkali resistance, good light resistance (after acrylic fiber), exposure for 1000 hours, strong 60-70% The hygroscopicity is very poor, the dyeing is difficult, the fabric is easy to wash and dry, and the shape retention is good. Has the characteristics of "washable and wearable";
Filament use: often used as low-elastic yarn to make all kinds of textiles;
Short fiber use: cotton, wool, hemp, etc. can be blended, industrial: tire cord, fishing net, rope, filter cloth, edge material. It is currently the largest amount of chemical fiber.
Nylon (sturdy wear)
The biggest advantage is that it is strong and wearable, which is the best one. Low density, light fabric, good elasticity, fatigue resistance, good chemical stability, alkali resistance and acid resistance.
The biggest disadvantage is that the sunlight resistance is not good, the fabric will turn yellow after a long time of drying, the strength will decrease, and the moisture absorption is not good, but it is better than acrylic fiber and polyester.
Filament use: mostly used in the knitting and silk industry;
Short-staple use: Most of them are blended with wool or wool-type chemical fiber, and are used for gabardine and vannamele.
Industrial use: cords and fishing nets, can also be used as carpets, ropes, conveyor belts, screens, etc.
The difference between polyester and nylon Nowadays, most of the bags are made of nylon or polyester. What is the difference between them? Now let's analyze it:
1. Polyester--- Polyester fiber Also known as POLYESTER, the property is good in gas permeability and moisture wicking. There is also a strong resistance to acid and alkali, UV resistance. Generally, the fabric of the multiple of 75D is polyester, such as 75D, 150D, 300D, 600D, 1200D, 1800D are polyester, the appearance of the fabric is darker than nylon, and is rough.
2, nylon - nylon - also known as Nylon, polyamide fiber. The advantages are high strength, high wear resistance, high chemical resistance, good deformation resistance and aging resistance. The disadvantage is that the hand feels harder. More famous are PERTEX, CORDURA. Generally, the fabric of multiples of 70D is nylon. For example, 70D, 210D, 420D, 840D, and 1680D are made of nylon (but the price is also made of polyester because of the price). The gloss of the fabric is brighter and the hand feels smoother. .
1. Sensory difference:
The gloss of the fabric is brighter, the feel is smoother than nylon; the appearance of the fabric is darker than nylon, and the coarser is polyester;
2, burning The difference between nylon and polyester is the simplest method of combustion! Polyester's very strong black smoke, nylon's white smoke, and the burning residue, polyester pinch will be broken, nylon plastic! The price of nylon is twice that of polyester. Nylon, the near flame is rapidly curled and melted into a white gel. It melts and blisters in the flame, and there is no flame when burning. It is difficult to continue burning after leaving the flame, and the celery flavor is emitted. After cooling, the light brown melt is not easy to be broken. . Polyester, easy to ignite, near the flame is melted, burning while burning black smoke, a yellow flame, emitting aroma, after burning, the ash is a dark brown lumps, can be broken with fingers.
3, with a nail scraper In addition to nail scraping, after nail scraping, there are obvious traces of polyester, the trace is not obvious is nylon, but this method is not as straightforward as the first method.
Functional, performance differences So, what are the differences in performance? Simply put, nylon has better performance than polyester, but at a higher cost than polyester.
Nylon products are better than polyester products in terms of abrasion resistance, strength, color fastness and gloss, and are not easy to produce dead wrinkles.
