We know that hot melt adhesive films are usually milky white or translucent films, but sometimes we can also see black hot melt adhesive films. How are black hot melt adhesive films made? Why do hot melt adhesive films have to be black? What is the use of black hot melt adhesive film?
PES hot melt adhesive film and hot melt adhesive mesh film are generally used to bond polyester (polyester) nonwovens. Polyester is the main component of PES film and mesh and compared with other components of hot melt adhesive film and mesh.
With the rapid changes in clothing, new processes continue to appear to replace the old ones. Hot melt adhesive film to bond fabrics instead of traditional seam technology has also become a technological direction of clothing production.
The hot melt adhesive films used for PI film bonding mainly include PA and PES. Because the hot melt adhesive films of PA and PES have some common characteristics to the polyimide PI film, the adhesive force is powerful, and the effect is perfect when bonding. Let's analyze it in detail.
These components can be used for hot melt adhesives. The hot melt adhesive has a solids content of 100%, does not contain solvents, is easy to store, is environmentally friendly and non-toxic, will not cause secondary pollution to the environment, and will not harm workers’ health;
Adhesive strength is the core performance of adhesives. Hot melt adhesives must be used on some occasions with extremely high strength requirements, especially those under large structural stress, and the adhesive strength must be improved.
For the surface treatment of the material to be bonded, the hot melt adhesive film is not as strict as other adhesives, but the dust and oil stains on the contact surface should also be properly treated to achieve a better bonding effect.
When you first contact a seamless hot melt adhesive film, you may not know precisely what this film-like product is. Seamless fit is a new process in clothing, and hot melt adhesive film is the core of this process.
