Polyester cotton gauze and pure cotton gauze are quite similar, so it is often difficult to distinguish them correctly. So how should they be distinguished? First of all, you can observe first. Generally speaking, the color of polyester cotton gauze is brighter than that of pure cotton gauze, and the color of polyester cotton is bright, and the fiber structure is more compact and fine. Compared with pure cotton yarn, the color of polyester cotton gauze often looks less bright and does not look very soft. Some polyester cotton gauze even has some cotton seed residues on its surface.
If it is still impossible to distinguish the two through eye observation, then you can touch them with your hand. Generally, pure cotton gauze is soft but not smooth, while polyester cotton gauze tends to feel a little slippery when touched with your hand. Combustion is the most intuitive way to distinguish them. Generally speaking, pure cotton gauze is usually ignited at one point, and its flame is yellow. After burning, its edge is often soft, and only a few gray black flocculent ashes will be left. When the polyester cotton gauze approaches the flame, it will begin to shrink and then melt, and then emit black smoke. Unlike the pure cotton gauze, its edges tend to harden after burning, and the ashes are black brown hard blocks that can be crushed.
As a common medical product in clinic, gauze undoubtedly plays a vital role. Therefore, relevant personnel should pay attention to carefully distinguish when purchasing gauze to ensure that its quality and function can be effectively played.
