Description

Film pasting process and application thereof
Technical Field
The invention relates to the technical field of clothing accessories, in particular to a film pasting process and application thereof.
Background
Nylon zippers, which are one category of zippers, have the advantages of being lightweight and multi-colored. In the aspect of tooth coloring, the existing nylon tooth making method comprises the following steps: 1. after the monofilament (tooth) is formed, electroplating treatment is carried out, and the electroplated tooth is sewn on the two cloth belts; 2. after the monofilament is formed, the monofilament is wound on a bobbin through teeth, vacuum plating is carried out, and then the teeth are sewn on a cloth belt. However, the two technical solutions have the following disadvantages:
the technical scheme 1 is that teeth are sewn on a cloth belt by a sewing thread, the electroplated color is only a metal color, and cannot be multicolor or colorful, and the technical scheme needs to carry out a surface spraying process under the condition that the teeth are not subjected to external force; in the technical scheme 2, the vacuum ion plating is performed by winding the teeth on the bobbin mold, the length of the teeth wound on one bobbin is limited, so that the number of joints of the teeth is large, the cost of the vacuum plating die is high, the efficiency is low, and the vacuum ion plating process is performed without external force on the teeth wound on the bobbin.
In addition, the prior art also discloses a process for sticking a film on teeth, in particular to a process for sticking a film directly through a photoelectric technology film with specified color after injection molding teeth (plastic teeth) are implanted; however, when the process is applied to the nylon zipper, the nylon zipper with the sewn teeth is directly subjected to film pasting, and because the teeth are provided with the suture lines, the gaps between the suture lines and the teeth are not pasted in place, and the surface film of the pasted teeth has a damage phenomenon. In the existing injection molding tooth sticking film, the component of teeth is PBT (polybutylene terephthalate), and different from the component of nylon teeth, the component of nylon teeth is PET (polyethylene terephthalate).
And the nylon monofilament removes to paste after the shaping, because the tooth can't remove oil completely, and the tooth of adding does not stereotype and has certain elasticity again, extrudees with elastic rubber tyer, and the effect of surperficial pad pasting is relatively poor, and the pad pasting fastness is also not good.
