Advantages And Disadvantages Of 4 Way Stretch Poly Fabric

　　4 way stretch poly fabric is a kind of chemical fiber clothing fabric that is widely used in daily life. Its biggest advantage is that it has good wrinkle resistance and shape retention. Therefore, it is suitable for outdoor products such as outerwear, various bags, and tents.

　　Advantages of 4 way stretch poly fabric:

　　First, the 4 way stretch poly fabric has high strength. The strength of the short fiber is 2.6-5.7cN/dtex, and the strength of high-strength fiber is 5.6-8.0cN/dtex. Due to its low hygroscopicity, its wet strength is the same as its dry strength, and its impact resistance is 4 times higher than that of nylon. Viscose is 20 times taller.

　　Second, the elasticity of 4 way stretch poly fabric is super strong. The elasticity is close to wool. When the elongation is 5% to 6%, it can be almost completely recovered. The 4 way stretch poly fabric can be quickly restored to its original shape by repeatedly rubbing it without leaving wrinkles. The elastic modulus is 22 to 141cN/ dtex, which is 2 to 3 times higher than that of nylon, which is unmatched by other fabrics.

　　Third, the heat resistance of 4 way stretch poly fabric is very good. It can be said that polyester has the best heat resistance and strong plasticity among chemical fiber fabrics. If it is made into a pleated skirt, it can keep the pleats well without excessive ironing.

　　Fourth, 4 way stretch poly fabric has better light resistance. Items made of 4 way stretch poly fabric are usually more light-resistant than natural fiber fabrics. It is no problem to expose 4 way stretch poly fabric items to the sun, and there is no need to worry about any side effects. This feature makes the lightfastness of 4 way stretch poly fabric almost on par with acrylic fabric.

　　Fifth, the 4 way stretch poly fabric has good wear resistance. The abrasion resistance is second only to nylon with the best abrasion resistance, and it is better than other natural fibers and synthetic fibers.

　　Sixth, the chemical resistance of 4 way stretch poly fabric is good. The textiles made of 4 way stretch poly fabric are not damaged much by acid and alkali, so some bleaching agents and oxidants do not work at all, and polyester textiles are not afraid of mildew and insects.

　　Disadvantages of 4 way stretch poly fabric:

　　First, the dyeability is poor. Because there is no specific dyeing group on the polyester molecular chain, and the polarity is small, it is difficult to dye, the dyeability is poor, and the dye molecules are not easy to enter the fiber. But the color fastness is good, not easy to fade.

　　Second, the resistance to melting is poor. Polyester is the most heat-resistant fabric in synthetic fabrics. It has thermoplastic properties and can be made into pleated skirts with long-lasting pleats. At the same time, polyester fabric has poor melting resistance, and it is easy to form holes when encountering soot, sparks, etc. Therefore, try to avoid contact with cigarette butts, sparks, etc. when wearing.

　　Third, the hygroscopicity is poor. Polyester fabrics have poor hygroscopicity, feel stuffy when wearing, and are prone to static electricity and dust, which affects appearance and comfort. However, it is very easy to dry after washing, and the wet strength hardly decreases, and it does not deform. It has a good wash and wears performance.

　　Fourth, it is easy to pilling. 4 way stretch poly fabric is one of the current synthetic fiber products. All synthetic fiber fabrics will have the phenomenon of pilling! And 4 way stretch poly fabric, as a kind of synthetic fiber, is no exception, so 4 way stretch poly fabric is no exception. The stretch poly fabric will pilling after a period of use.

　　The biggest advantage of 4 way stretch poly fabric is that it is not easy to deform and become wrinkled. It is more suitable for sofas, dining chairs, and other places in the home. There is no need to worry about leaving wrinkles and affecting the aesthetic effect. Therefore, before choosing textiles, learning about textile fabrics Features are necessary.
