1. When pulling the head, it is found that the stickers are attached to one layer of cloth, while the other layer of cloth is light, why? (Is it best to have the same amount of glue on both sides of the fabric?)
There are several reasons why the stickers are attached to a layer of cloth:
a, poor adhesion
b. The adhesion is better, but the strength of the glue is higher
Generally speaking, when nylon tapes and some EP tapes are on the slider, it is easier to have glue on both sides, and the thickness of the glue is similar, while cotton canvas tapes are prone to have glue attached to the above-mentioned layer of cloth, and the other This case where the layer cloth is light. Of course, this will also happen to some EP tapes with poor adhesion or EP tapes with better adhesion but higher adhesive strength.
