Abstract
Abstract The method for coating textile substrates such as carpets and textile fabrics with a latex backing is improved by replacing up to about 40% by weight of the normally employed latex solids in the coating composition with an alkali metal silicate extender such as sodium silicate, and further adding a latex compatible metal compound which will react with the silicate extender to render the silicate values less water soluble. The improved backing layer provides a significant cost reduction, increased fire retardancy and beneficial modification of other properties of the coated substrate.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
104 words
In a method for coating a textile substrate with a latex-based composition comprising the steps of applying said composition to said substrate and heating to dry said composition and bond it to said substrate, the improvement comprising formulating said latex-based composition by replacing from about 5 to about 40 parts by weight of the latex normally present in said composition based on 100 parts dry latex solids with an alkali metal silicate extender, and further adding to said composition a latex compatible metal compound which will react in situ with said silicate during said drying step to render said silicate extender less water soluble.
Claim 2
Dependent Claim
104 words
In a method for coating a textile substrate with a latex-based composition comprising the steps of applying said composition to said substrate and heating to dry said composition and bond it to said substrate, the improvement comprising formulating said latex-based composition by replacing from about 5 to about 40 parts by weight of the latex normally present in said composition based on 100 parts dry latex solids with an alkali metal silicate extender, and further adding to said composition a latex compatible metal compound which will react in situ with said silicate during said drying step to render said silicate extender less water soluble.
