Custom heat transfer printing film uses powder hot melts. During the process, a clear liquid adhesive is applied to the wet ink layer. Then hot melt powder 80-200 mm is scattered on top. After the excess powder is shaken off, a thin layer of hot melt material will allow the design to lay seamlessly on the fabric, without manipulating the quality of the textile during the transfer.
Custom heat transfers are ideal for large product quantities since the powder hot melt allows for fast application while maintaining consistent printing capabilities. Powder hot melts offer specific requirements to make the process successful, including:
Strong compatibility: The nature of each polymer is unique and needs to be adapted to the textile for successful bonding. Thermoplastic polyurethane (TPU) based HM can help bond the ink to soft or extremely elastic fabrics, and make the design outlast the garment without premature cracking.
Washing resistance: In order to avoid the bonding from breaking down prematurely, polyamide and polyester based powder adhesives will offer excellent plasticizer resistance and high wash and dry-cleaning resistance.
