PROCEDURE FOR PRODUCTION OF HEAT SENSING DEVICES ON BASE OF POLYMERS Russian patent published in 2010 - IPC D06P5/20 G11B11/12 

FIELD: textile, paper, polymer fibre.

SUBSTANCE: invention refers to production of heat sensing devices on base of polymers and can be implemented for control over temperature in various industrial processes and in household use. Here is disclosed the procedure for production of heat sensing devices on base of polymers by means of polymer treatment with solution of dye; further polymer is dried at temperature below temperature of glass transition. As polymer there is used a polymer item of elongated shape, such as film, fibre, band, pipe, or rod, fabricated of plasticised or non-plasticised amorphous or amorphous-crystallised polymer drawn into adsorption active medium at temperature below temperature of polymer glass transition. As dye there is used not thermo-chromic dye chosen from a group including Rodamin 6 ZH, Methyl green and Methylene blue; also polymer is treated with dye solution at temperature below temperature of polymer glass forming.

EFFECT: facilitating simplified procedure for production of heat-sensing devices on base of polymers, expands range of implementation, also produced heat-sensing devices with irreversible mode of operation.
