  • Patent number: 5543214
    Abstract: A thermo-adhesive product is formed from a backing fabric with a thermo-adhesive layer deposited on its surface. In a preferred embodiment, the thermo-adhesive layer is deposited in a discontinuous fashion as dots. The thermo-adhesive layer is formed of polymers which are non-tacky at ambient temperatures but which become tacky and plastic at a first elevated temperature range which is beneath the critical temperature for the polymeric composition, and which become thermo-setting at a second elevated temperature range which is above the critical temperature. In alternate preferred embodiments, the thermo-adhesive compositions can be cross-linked under the influence of radiation from an electron beam or UV radiation.
