Description

Technical Field

[0001] The utility model relates to the technical field of wiping cloths, and more specifically to a wiping cloth made of a PVA hydrolyzed material. Background Art

[0002] PVA (Polyvinyl Alcohol) is a biodegradable polymer material with the characteristics of good density, high crystallinity, strong adhesion, etc. The film made of PVA is flexible, smooth, oil-resistant, solvent-resistant, abrasion-resistant, gas-barrier, and water-resistant after special treatment, and has a wide range of uses. The degree of polymerization of PVA affects its degree of hydrolysis. The higher the degree of polymerization, the lower the degree of hydrolysis. PVA is a green and environmentally friendly material and is also widely used in the field of wiping cloth manufacturing, such as for making mop cloths, oil-absorbing cloths and water-absorbing cloths. However, for the structure commonly used in the prior art in which the PVA layer is coated on the fiber cloth layer or the base cloth layer, it has limited adsorption capacity and often requires repeated wiping to achieve the ideal wiping effect. The wiping effect is not good enough, the wiping efficiency is low, and it is easy to delay the user's wiping time. Utility Model Content
