Materials such as leather and microfiber are widely used in the manufacture of clothing and shoes. Most of them involve composites between different materials when used. Today, when hot melt adhesive film composites are now widely popular, microfiber composites place higher demands on the properties of hot melt adhesive films. While ensuring sufficient adhesive strength, it is also necessary to have sufficient softness. The plastic feel of the material after the hot-melt adhesive film is not too strong to ensure a good feel.
