Seamless underwear is a kind of underwear that many female friends like very much now. Seamless underwear is also called seamless underwear. It means no trace, no sewing seam. The reason why it is loved by many female friends is because it has no trace characteristics. Compared with traditional ordinary underwear, seamless underwear has better experience in comfort, no tightness in wearing, and a more natural and full curve. Another important reason is that the weightless underwear is lighter, which is what ordinary underwear does not have.
Seamless underwear can be market-oriented and its bonding technology is inseparable. The one-piece production process makes the seamless technology develop. The technology of seamless fit is currently divided into three main types:
The first type: glueless bonding technology: the use of glueless bonding is mainly limited to chemical fiber or blended fabrics. The work of this kind of bonding is far away from the action range in which the high-frequency vibration wave is utilized, and the surface molecules of the fabric itself are violently smeared with each other to generate heat, thereby achieving the effect of fusion bonding. However, the limitation of this fit is that chemical fiber fabrics must be used, and natural plants do not have such characteristics. Therefore, this kind of bonding technology is basically not used in the production of seamless underwear.
The second type: glue fit: glue fit can be said to be the main means of seamless fit over a period of time. The glue mainly has a solvent or an aqueous binder. The water or the solvent is used as a medium to disperse the resin in the medium, and after the water or the solvent is volatilized, the formation reaches the bonding strength, and the curing process is a physical reaction. The other is a moisture-curing adhesive, which is available in both liquid solvent and solid hot melt types. The solvent type is applied directly to the fabric, and the solid state needs to be heated to become liquid.
The third type: hot melt adhesive film bonding: hot melt adhesive film bonding is to make the hot melt adhesive into a film shape, which not only ensures the uniformity of the bonding, but also has a soft hand feeling, and can be refined operation at the same time. There will be no defects such as spills. The hot melt adhesive film penetrates into the fabric under high temperature and high pressure, and forms a logistics interlock structure to achieve the bonding strength after cooling and crystallization.
Underwear as a woman's close-fitting clothing and direct contact with the skin, not only requires comfortable wearing, but also safe and hygienic! Traditional glue bonding will inevitably have a lot of chemical residues. The hot melt adhesive film is much safer and healthier than the traditional glue. The hot melt adhesive film needs to be melted at a high temperature during the manufacturing process. During the high temperature process, some harmful substances will be volatilized and cleaned. When the temperature melts, there will be no more volatile substances!
The hot-melt adhesive film composite underwear has the characteristics of softness and high resilience. After the material is glued, the cup to the strap is completely free of seams and traces, and one-piece molding, the appearance does not have obvious wrinkles, and is simple and beautiful.
With the advancement of hot melt adhesive film production and processing technology and the continuous development of new products, in addition to hot melt adhesive film can be used for the composite of seamless underwear, a new type of hot melt composite product - hot melt mesh film, has also Started to apply to the production and processing of seamless underwear. The hot-melt mesh film and the hot-melt adhesive film are similar in appearance, but the production processes of the two are completely different, and the product characteristics are also greatly different.
