Hot drill is a new type of clothing material, it is a hot melt adhesive, through heating, paste on the fabric, leather and other surfaces. At present, there are two kinds of hot stamping, one is regular heating and paste, and one is ultrasonic heating and paste.
Conventional heating and paste: it is the use of hot iron, heat transfer machine and other equipment, through the heat transfer method, to the drill in the overall heating, to melt hot glue, so that drilling and paste on the garment surface.
Paste in such a way that will produce a lot of heat, energy consumption and the risk of fire. Part of the light color of fabric is heated, easy yellowing. Affect the strength of the fabric. At the same time, low efficiency, using a batch, because of the appearance of drill and fabric, will produce some diamond paste unreliable.
Ultrasonic heating and paste: it is used in the transmission process of ultrasonic wave, and it is heated by the principle of sound resistance. Therefore, the heat generated by it is local, and it is generally in the fabric and hot drill, which produces a large amount of heat, and melts the hot glue to achieve the purpose of bonding the fabric and ironing.
Glue in such a way that only produce local high temperature, the use of safe, less energy consumption. High efficiency. And will not affect the texture of the fabric. Because it is one of the heated, each hot drilling can be quite strong glue.
Compared with conventional heating more than two kinds of process, is a relatively old technology, is now in the gradually replaced. The ultrasonic hot drilling machine, with its powerful advantages is the occupation of the industry. But because of the popularity of new technology needs a process, a lot of people in the use of ultrasonic heating when the new things, also met a lot of problems. This needs to be in the outfits of unremitting efforts, improve technology, technology popularization, and simplify the application.
