Some Knowledge Points For Using Polyester Yarn?

　　The polyester yarn has a wide range of applications. We must know its basic definition before using it.

　　Polyester yarn is widely used in various industries. Polyester yarn is made of polyester chips and masterbatch (color powder) through high-temperature melt spinning. If everyone uses it, there is no need for dyeing, which shortens the production process of textile products, solves the problem of environmental pollution during the dyeing process, and avoids the damage caused by dyeing to fiber performance. In addition, it is also necessary to know that textile products produced using colored polyester yarns have good fastness properties such as soaping, sunlight, and rubbing. Colored polyester yarns of different colors have enriched the options of textile enterprises and become the preferred silk yarn material for terminal products in the market. Some short fibers have a strength of 2.6-5.7cN/dtex, and high-strength fibers have a strength of 5.6-8.0cN/dtex. Due to its low hygroscopicity, its wet strength is the same as its dry strength, and its impact strength is 4 times higher than that of nylon and 20 times higher than that of viscose fiber. Therefore, the polyester yarn we are talking about today is super elastic. The elasticity is close to that of wool. When the elongation rate is 5% to 6%, it can be almost completely recovered. Polyester fabric can quickly return to its original shape through repeated rubbing, leaving no wrinkles. The elastic modulus is 22~141cN/dtex. Nylon is 2 to 3 times higher than other fabrics.

　　The polyester yarn has insufficient hygroscopicity and poor hygroscopicity, while the polyester fabric has poor hygroscopicity, so polyester clothes will feel hot when worn, and it is easy to generate static electricity and be contaminated with dust, which affects the appearance and comfort, but it is very simple and stuffy after cleaning, sometimes you will find it There is almost no decline in wet strength, no deformation, and good wear resistance. The dyeability is poor, because there is no specific dyeing gene on the polyester molecular chain, and the polarity is small, so it is difficult to dye, the dyeability is poor, and the dye molecules are not easy to enter the fiber, but the color fastness after dyeing is good, and the color is not easy to fade. In addition to these words, it is easy to pilling when used, so you must know that polyester fabric is a kind of synthetic fiber product, and all synthetic fiber fabrics have a pilling phenomenon, so after a period of use, polyester yarn products will Pilling occurs. Of course, it is recommended that you look at the appearance when buying. The appearance of fabrics is closely related to fabric organization. Therefore, when choosing polyester silk yarn, it is also necessary to carefully observe whether the tissue is basic or variable, the gap between the coils, whether it is tight, and whether the handle is soft or rough.
