How to distinguish artificial cotton and pure cotton? Artificial cotton is the common name of viscose fiber, which refers to cellulose extracted from cellulose raw materials such as wood and plant leaves, or cotton linters as raw materials, processed into spinning dope, and then made by wet spinning The man-made fiber; pure cotton fabric is a textile made of cotton as raw material, through the loom, the warp and weft yarns are interwoven vertically and horizontally. At present, according to the actual source of processed cotton, it is divided into virgin cotton fabric and recycled cotton fabric.
The appearance of rayon is very similar to cotton cloth, and its distinguishing methods are mainly based on the following points:
1. Finish: Artificial cotton cloth has a flat surface, few yarn defects, no impurities, fine and smooth; while cotton shells and impurities can be seen on the surface of cotton cloth, and the finish is not as good as artificial cotton cloth.
2. Yarn count uniformity: The yarn count of rayon fabric is even, with few yarn defects; while the yarn count of pure cotton is not as uniform as rayon, especially for medium coarse cloth.
3. Hand feeling: regardless of the thickness of the rayon fabric, the hand feeling is mostly soft, while the cotton cloth has a slightly rough feel.
4. Color and luster: The luster and color of rayon cloth are good. Compared with cotton cloth, rayon cloth is more vivid and beautiful.
5. Wrinkle: rayon cloth is easy to wrinkle. When you hold the cloth with your hands and spread it out, there will be a lot of wrinkles and it is not easy to recover in time; although cotton cloth has wrinkles, it is lighter than rayon.
6. Drapability: The drape of rayon is better, and the drape of cotton is not as good as that of rayon.
7. Strength: The strength of rayon cloth is lower, not as good as cotton cloth. Especially in a humid environment, rayon has poor fastness. When drawing silk from the edge of the cloth, it is more easy to break when stretched. Therefore, rayon is mostly thicker, not as light as pure cotton linen yarn.
