How to distinguish the materials of microfiber cloth, non-woven fabric, and double-sided fleece

How to distinguish the materials of microfiber cloth, non-woven cloth, and double-faced fleece? The cloth can be distinguished according to the following characteristics. The characteristics of microfiber cloth: soft and light. Stick the microfiber cloth on the ordinary cloth clothes. When the clothes are in the vertical state, the microfiber is still attached to the clothes. That means the fiber is fine enough and it is a microfiber cloth. The real microfiber is rolled into a ball and unfolds slowly, while the fake microfiber is quickly loosened. The characteristics of non-woven fabrics: pay attention to whether the light transmittance of the cloth surface is consistent (this is an important and simple method to judge the uniformity of the cloth surface). Then spread it on a flat ground, the product with good uniformity, there should be no undulations on the cloth surface. Observe 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, burn it completely with fire, observe the burning residue, good product, the residue is small and flat, produced from inferior materials, the residue has many tiny particles of dust. The characteristics of double-sided fleece: soft hand, full texture, good warmth, and comfortable to wear next to the body, but the disadvantage is that the napping destroys the structure of some fibers, so the strength will be greatly affected.
