Abstract (en)

[origin: WO2019171084A1] A fabric composition for use in a garment, such as a maritime safety vest, which undergoes an exothermic reaction when in contact with water to produce heat and mitigate the effects of cold exposure from the water. The fabric composition comprises: at least one layer of fabric; a hydrateable metal compound (22a), such as MgCl2.2H20 or Mg(CIO4)2 having the general formula MXa.bH2O (where b can be from 0 to 10) and Xa.bH2O usually includes at least one oxygen atom; and a metal oxide such as CaO having the chemical formula MdO. A series of semi-permeable bags containing, alternately, the hydrateable metal compound (22a) and the metal oxide (22b), may be provided between two layers of fabric (11,12). One further advantage of the fabric is that the reaction products are not gaseous or toxic and remain in an unchanged solid state.
