How to identify non-woven fabric

How to identify non-woven fabrics. Non-woven fabrics are divided into domestic fabrics and imported fabrics. Domestic fabrics are relatively thin, soft and have a simple fluff. Imported fabrics are relatively thick, flat, and stiff, with a better hand feeling, and are more ideal in manufacturing. . The edges of dust-free cloth, dust-free scrubbing cloth, microfiber dust-free cloth, and microfiber scrubbing cloth are sealed by the most advanced edge trimming machine. After scrubbing, there will be no particles and thread ends, and the decontamination ability is strong. Appearance target identification of non-woven fabric: randomly select a sample of 2 meters for testing, open it in a place with light, and visually inspect the fabric for unqualified defects such as broken threads, lumps, etc. Pay attention to whether the light transmission function of the cloth surface is common. This is an important and simple way to judge the uniformity of the cloth surface. Then spread it on a flat ground with good uniformity. The cloth surface may not have the appearance of ruggedness. If there is, you will be in trouble when processing the pieces. Physical target identification of non-woven fabric on the cloth surface: Investigate whether the cloth surface is shiny. Is there any fiber floating on the surface, if it is dull or has a lot of floating silk, it is probably produced from recycled materials. Tear a piece of cloth and burn it thoroughly with fire. Investigate the burned residues. Good products have few and flat residues. The residues are produced from inferior materials. The residues contain many fine particles of dust. If you agree at all times, you can take one square meter and expose it to the sun, and tear it with your hands, and it will simply tear like paper.
