The surface of polyester is smooth and the internal molecules are tightly arranged. Polyester is the most heat-resistant fabric among fiber fabrics. It is thermoplastic and can be made into pleated skirts with durable pleats. Next, Ocean star Special Chemical Fiber, a hot-melt yarn manufacturer, will also list the advantages and disadvantages of polyester yarn fabrics based on its own experience.
⒈Good light resistance. Lightfastness is second only to acrylic. Polyester fabrics have better light resistance. In addition to being worse than acrylic fibers, their light resistance is better than natural fiber fabrics. Especially the light resistance behind the glass is very good, almost on par with acrylic.
⒉Good wear resistance. The abrasion resistance is second only to nylon in abrasion resistance, and is better than other natural fibers and constituent fibers.
⒊The surface of polyester is smooth and the internal molecules are tightly arranged. Polyester is the most heat-resistant fabric among fiber fabrics. It is thermoplastic and can be made into pleated skirts with durable pleats. At the same time, polyester fabric has poor melt resistance and can easily form holes when exposed to soot, sparks, etc. Therefore, you should try to avoid contact with cigarette butts, sparks, etc. when wearing it.
⒋Heat-resistant polyester is made by melt spinning. The formed fiber can be heated and melted again to become a thermoplastic fiber.
⒌Good elasticity. The elasticity is close to wool, and it can almost recover when stretched by 5% to 6%. The wrinkle resistance is better than other fibers, that is, the fabric does not wrinkle and has good dimensional stability. Polyester fabric has high strength and elastic recovery ability, so it is durable, wrinkle-resistant and requires no ironing.
⒍High strength. Because of its low hygroscopicity, its wet strength is essentially the same as its dry strength. The impact resistance is 4 times higher than nylon and 20 times higher than viscose fiber.
⒎It has poor hygroscopicity and feels hot when worn. It is also prone to static electricity and dust contamination, which affects the appearance and comfort. However, it is very easy to dry after washing, and the wet strength hardly decreases, does not deform, and has good washable and wearable properties.
⒏The dyeability is poor, but the color fastness is good and it is not easy to fade. Because there are no specific dyeing groups on the polyester molecular chain and the polarity is small, it is difficult to dye, the dyeability is poor, and the dye molecules cannot easily enter the fiber.
⒐Corrosion resistance. Resistant to bleach, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids. Resistant to dilute alkali and not afraid of mold, but hot alkali can cause it to decompose. It also has strong acid and alkali resistance and UV resistance.
Fabrics woven from general polyester filaments have the advantages of good strength, smoothness and crispness, easy washing and quick drying, etc. for clothing. However, they have shortcomings such as hard hand feeling, poor touch, soft luster, poor breathability, and poor hygroscopicity. If compared with silk fabrics, the distance is larger. Therefore, the silk thread structure must first be simulated to simulate silk, so as to eliminate the shortcomings of poor wearing function
