Polyester bonded thread is famous for polyester film and polyester fiber. In the past, it was difficult to bond without surface treatment. Recently, co-condensed amorphous polyester adhesive is used for bonding, and firm bonding strength can be obtained.

1. Heat sealing method, polyester bonded thread without surface treatment can not use heat sealing method, if benzyl alcohol or anisole is gently applied, it can be heat sealed at 250~280℃.
2. Synthetic adhesive bonding, polyester bonded thread often uses neoprene rubber, polyisobutylene, nitrile rubber, polyester vinyl ester, vinyl acetate-acrylic acid copolymer, vinyl chloride-vinyl acetate copolymer for bonding. Polyacrylate, polyamide, linear polyester, melamine formaldehyde resin, silicone, polyurethane, unsaturated polyester resin, co-condensed amorphous polyester and other adhesives.
The polyester bonded thread is made by the copolymerization of polyester and other acids or alcohols, and it can bond firmly with polyester.
