CHEMICAL PROTECTIVE HOT-MELT BINDING COMPOSITE MATERIAL FOR MANUFACTURING OF CHEMICAL PROTECTIVE CLOTHING Russian patent published in 2010 - IPC A62D5/00 

FIELD: medicine, life saving equipment.

SUBSTANCE: invention relates to the production of multilayer chemical protective materials used for the manufacturing of special purpose chemical protective clothing for rescuers of rescue services. Chemical protective hot-melt binding composite material for the manufacturing of chemical protective clothing contains a carbon-filled crepe paper as a middle sorption layer, reinforced on both sides with cloth having hot-melt binding dot coating containing 58-60 wt % of unbleached sulphate cellulose, 30-40 wt % of absorbent carbon and while a sorption layer contains 2-10 wt % of synthetic latex. Types of the synthetic latex used are DVHB-70 or BCM-65 "B".

EFFECT: increase in the operating characteristics: abrasion resistance, air permeability, vapor permeability, wet-strength and water consumption, as well as increase the life of the finished product and simplifying of the process of material manufacturing keeping protective ability of the composite material.
