cotton products are very popular, but their cost is high, especially high-quality high count cotton textiles, which are expensive. Some unscrupulous businessmen use low-cost purified fiber or blended materials to pretend to be pure cotton products. If consumers can master some identification methods, they can avoid being cheated. The simplest and direct method is hand feeling and visual inspection. If the raw material is in loose fiber state, such as cotton wadding, it can be judged according to the appearance, color, hand feeling and hand pull strength of the fiber. Natural cotton fiber is thin and soft, short in length and poor in uniformity, while chemical fiber is generally neat in length, long in length, pure in color and unnatural in luster. If it is a textile that has been made, the pure cotton products generally have a good hand feel and are relatively soft, especially the knitwear is softer than the woven products, and there are obvious wrinkles when grasping, while the cotton products with chemical fibers are relatively stiff and almost no wrinkles. Except for mercerized cotton that has been specially treated, cotton textiles do not feel very smooth, not as smooth as polyester, blended and other products. The color is usually natural, and there is no special luster like silk and chemical fiber. There is also talk about the shortcomings of cotton: washing cotton will shrink (normal does not affect the use). Another commonly used method is combustion. You can take a yarn from the corner of the textile and ignite it for observation to determine whether it is cotton. Cotton and other fibers with cellulose as the main component burn rapidly when they come into contact with the flame. After leaving the flame, they can continue to burn, giving off the smell of burning paper, leaving a small amount of gray ash after burning. When protein fibers such as wool burn, they will have the smell of burning hair, and the ashes left after burning are black and crisp. Although synthetic fibers can also burn in fire, they do not burn rapidly when approaching the flame, but melt and shrink, and the residue after combustion is hard spherical
