A hot melt line is a linear joining material made of a heat-meltable polymer. When the book is bound, the temperature can reach a certain level before it can be melted and bonded to the paper. The materials used to make the hot melt line are mainly polyester and nylon. The melting point of polyester: 110-120°C The melting point of nylon is 85-90°C. Specifications: 20D, 30D, 50D, 70D, 100D, 150D/3, etc. According to the needs of the guests to order.
The hot melt link book is an advanced process, and the wire can be glued to the cloth, but it has not been valued and popularized for various reasons。 If this kind of process can be widely used, it can replace the finishing and sewing of the lock line, the sewing order, the wire binding and the like, thereby saving a lot of manpower and material resources。
Hot melt lines are widely used in woven, garment, automotive interior, carbon fiber unidirectional fabrics, basalt fiber / glass fiber / aramid fiber fabric in the warp and weft direction of hot melt fixation. Articles woven with hot-melt lines are very bottle-fixed and are not easily deformed.
