Abstract
The invention relates to heat-bonding products in which a heat-adhesive layer is applied to a textile support. The heat-adhesive layer comprises cross-linkable polymers including initially at least two reactive and/or reactivable functions, the first of these functions is activated at the time of depositing the heat-adhesive layer on the support. A second reactive and/or reactivable function is activated during application of the heat-adhesive layer to the textile support.
Claims3
A heat-bonding product comprising:
- a textile support having at least one surface;
- and a single heat-adhesive layer deposited upon a surface of said support;
- wherein said heat-adhesive layer comprises a hydroxylated polybutadiene and a diol as a chain activator, an isocyanate having free isocyanate groups, and an isocyantate having isocyanate groups blocked by a blocking agent;
- the free isocyanate groups reacting with the hydroxylated polybutadiene under substantially different conditions than said blocked isocyanate groups.
