Process for producing synthetic chamois leather-like material having improved water absorbency and abrasion resistance
Abstract
Abstract IMPROVED SYNTHETIC CHAMOIS-LIKE MATERIAL BY PROVIDING A WATER ABSORBENT NON-WOVEN TEXTILE FLEECE, IMPREGNATIN THE FLEECE AT LEAST ONCE WITH A LIQUID FORM A BINDER MATERIAL, AT LEAST PARTIALLY DRYING THE IMPREGNATED FLEECE WHEREBY CAUSING DEPOSITION OF THE IMPREGNATED BINDER MATERIAL AS LAMELLA PREDOMINANTLY AT THE CROSSING POINTS OF FIBERS WITHIN THE TEXTILE FLEECE, APPLYING TO BOTH MAJOR SURFACES OF THE BONDED FLEECE A LIQUID FORM COAGULATABLE RUBBER LATEX MATERIAL UNDER SUCH CONDITIONS THAT THE LATEX REMAINS ON THE SURFACE OR SUBSTANTIALLY ONLY AT THE SURFACE OF THE BONDED FLEECE, AND CAUSING THE RUBBER CONTENT OF THE COAGULATABLE LATEX TO COAGULATE BY HEATING THE COATED FLEECE TO ABOUT 40 TO 80*C. THE COAGULATED LATEX FORMS A DISCONTINUOUS PARTICULATE COATING ON THE SURFACE OF THE FLEECE WHICH SIGNIFICANTLY REDUCES PILLING.
