An epoxy resin-free coating system based on thermoplastic polyesters into which a polyester is incorporated as adhesion-promoting additive, which polyester is non-toxic.

Adhesion-promoting additive for coatings based on thermoplastic

Conventional hot-melt adhesive compositions for the coating of textile sheet structures exhibit problems in respect of resistance to washing and cleaning. The presence of an epoxide in hot-melt adhesive composition enables the production of cleaning-resistant laminated materials having a particularly high level of wash resistance.

Hot-melt adhesive composition for the coating of interlining material

A hot-melt adhesive composition for the preparation of cleaning-resistant laminated materials which have a particularly high wash resistance.

Polyether esters are employed for the adhesive bonding of textiles since they are resistant to washing and dry cleaning. The polyether esters of the prior art have the disadvantage that they often exhibit poor adhesion with critical outer materials such as, for example, silk. By means of the polyether esters according to the invention, it is possible to bond sensitive textiles effectively at very low temperatures.
