Chemical fiber fabric is a new type of clothing developed in modern times, and there are many kinds. Here, it mainly refers to fabrics made of pure chemical fibers, blended or interwoven, that is to say, fabrics made of pure chemical fibers, excluding fabrics blended or interwoven with natural fibers. The characteristics of chemical fiber fabric are determined by the characteristics of chemical fiber woven into it.
In the long process of human development, only dozens of natural fibers have been discovered and really utilized. Mankind has entered the era of chemical fiber, and hundreds of new varieties of chemical fiber have been invented in just a hundred years. As an artificial polymer, chemical fiber can be designed in advance in the production process. In addition to endowing chemical fiber with new functions in design and production, the characteristics and characteristics of polymers that constitute chemical fiber itself also have functional factors.
Identification skills of chemical fiber fabrics
1, pure cotton fabric has no "aurora". Press the cloth flat with both hands to increase a certain tension. The fabric and the body are at a 45-degree angle downward. Look at the light source to see if there is any dazzling light flashing. If there is, it proves that there is chemical fiber.
2. The pure cotton fabric feels full and thick, and looks like the same thickness fabric. Pure cotton feels very muscular, while chemical fiber is soft, loose and boneless.
3. You can draw a thin thread from the seam of clothes. Cotton fiber will not melt and shrink when it is close to the flame, but will burn immediately when it meets the flame. When it burns, it will smell like burning paper, but after it is exhausted, it will be fine and soft gray-black or gray-white flocculent ash, which will not burn. If the burnt ash has particles, it is a chemical fiber product!
4. Pure cotton has obvious wrinkles after kneading. After the fabric is folded in half, it is scraped with nails, and there are obvious fold lines, while the chemical fiber fabric has no folds after being pinched.
