Title:
COMPOSITE EXOTHERMIC NON-WOVEN MATERIAL AND METHODS FOR THE PRODUCTION AND ACTIVATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2001/012749
Kind Code:
A1
Abstract:
The present invention relates to a composite exothermic non-woven material from polymeric fiber with a filler capable of producing heat when coming into contact with air, whereby the ratio between the polymer and the filler (in weight) is comprised between 1:1 and 1:4, preferably between 1:3 and 1:4. A mixture of metallized finely dispersed powder iron can be used as a filler, whereby said powder iron has a grain size of 20 micrometers or less. Such filler can also contain activated carbon and/or vermiculite and/or water, for example, in the following proportions: metallized powder iron 0.717 gr, activated carbon 0.151 gr, vermiculite 0.026 gr and water 0.106 gr. The polymeric fibers can be an acrylnitrile and methylacrylate copolymer, with a proportion, in weight per cent, of 95:5. The invention also relates to a method for production of such exothermic composite non-woven material and to a method for activating said non-woven material.
