Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
54 words
A textile fabric-bondable, thermo-adhesive product comprising a backing fabric and an adhesive layer made up of dot patterns deposited on its surface, the adhesive layer comprising a thermo-plastic polymer and a cross linking agent for its thermoplastic polymer wherein the cross linking agent is isolated from the thermoplastic polymer by heat- or pressure-releasable micro-encapsulation.
Claim 2
Dependent Claim
54 words
A textile fabric-bondable, thermo-adhesive product comprising a backing fabric and an adhesive layer made up of dot patterns deposited on its surface, the adhesive layer comprising a thermo-plastic polymer and a cross linking agent for its thermoplastic polymer wherein the cross linking agent is isolated from the thermoplastic polymer by heat- or pressure-releasable micro-encapsulation.
Claim 3
Dependent Claim
35 words
Thermo-adhesive product according to claim 1 characterized in that the adhesive layer includes a catalyst whose concentration contributes to determine the speed of the reaction produced when the cross linking agent is released and activated.
Claim 4
Dependent Claim
44 words
Thermo-adhesive product according to claim 1 characterized in that the speed of the cross linking reaction is arranged so that when it is subjected to a temperature of about 130° C. the adhesive layer passes quickly through an adhesive state and then becomes thermo-setting.
Claim 5
Dependent Claim
17 words
Thermo-adhesive product according to claim 1 characterized in that the cross linking agent is isolated in micro-spheres.
Claim 6
Dependent Claim
20 words
Thermo-adhesive product according to claim 1 characterized in that the cross linking agent is released by a rise in temperature.
Claim 7
Dependent Claim
20 words
Thermo-adhesive product according to claim 1 characterized in that the cross linking agent is freed by an increase in pressure.
Claim 8
Dependent Claim
15 words
Thermo-adhesive product according to claim 1 characterized in that the thermo-adhesive polymer is a copolyamide.
Claim 9
Dependent Claim
15 words
Thermo-adhesive product according to claim 1 characterized in that the thermo-adhesive polymer is a polyester.
Claim 10
Dependent Claim
16 words
Thermo-adhesive product according to claim 1 characterized in that the cross linking agent is an aziridine.
