One. The color requirements of the glue should be different. Yellow hot melt adhesive is recommended if the color has no special requirements on the color itself. Generally, the Yellow hot-melt adhesive is better than the white stickiness. Low temperature hot melt adhesive
Two. The surface is treated by the surface. Hot melt adhesive is not as strict as other adhesives for the surface treatment of the finished products, but the dust and oil stains on the surfaces should be properly treated to make the hot-melt adhesive better play the role of adhesion. Three. Work time. Fast operation is a major feature of hot melt adhesive. The operation time of hot melt adhesive is usually about 15 seconds. With the extensive application of modern production mode -- pipeline, the operation time of hot melt adhesive is shorter and shorter. For example, the time required for book binding and speaker production to hot melt adhesive is 5 seconds. Four. Resistance to temperature. Hot melt adhesive is sensitive to temperature. When the temperature reaches a certain level, the hot melt adhesive starts to soften, lower than a certain temperature, and the hot melt adhesive will become crisp, so the choice of hot melt adhesive must take full account of the temperature change in the environment of the product. Five, stickiness. The stickiness of hot melt adhesive is early stickiness and later stickiness. Only the consistency of the early viscosity and the later viscosity can make the hot melt adhesive and the material keep stable. In the production process of hot melt adhesive, it should be guaranteed with oxygen resistance, halogenicity, acid resistance and plasticization. The stickiness of hot melt adhesive is different by the material of the next material. Therefore, different hot melt adhesives should be selected according to different materials.
It is also a big hand in DIY use, such as with the small stuff, making PP cotton cloth Chinese knot. Now the hot melt adhesive film Market: PES/PA/EAA/EVA/TPU,. This kind of hot melt adhesive film is an ideal environment-friendly adhesive material, widely used in embroidery armbands, trademark label, adhesive, suitable for
Clothing, shoes and caps, bags, medical, military coat, sportswear, toy products and other fields. It has low melting point, high elasticity, dry / washed, colorless, transparent, wear-resistant, cold resistant, acid resistant, mildew proof and antibacterial properties. Strong adhesion, easy operation, low cost and can replace the traditional needle. Hot melt adhesive film in the embroidery industry is called hot glue or adhesive, due to its smooth surface without viscosity, acid and alkali resistance, washable, dry cleaning and good performance of tensile
Force, strong adhesive force, low melting point, and then generally conforms to all cloth processing standards, over the years the domestic embroidery industry has gradually replaced the European and American standards, low quality rough seam LOGO (embroidery badges, armbands, and other chapters, the hot glue glue) is the adhesive film industry's Embroidery sure
