Aqueous latex base binder of a synthetic polymer for manufacturing tufted floor covering having improved wear-resistance. The content of hydrosoluble compounds dissolved in the aqueous phase in the latex is less than 0.5% by weight in relation to the polymer.

Binder for manufacturing tufted floor coverings

Aqueous latex base binder of a synthetic polymer for manufacturing nonwoven fabrics, and specifically webs for sanitary use having improved breaking strength. The content in the latex of hydrosoluble compounds dissolved in the aqueous phase is less than 0.5% by weight in relation to the polymer.

Binder for manufacturing nonwovens

A method of preparing homo and co-polymers of vinyl chloride in the form of a powder adapted to give plastisols, in which a latex of homo or co-polymers of vinyl chloride, containing from 30 to 60% by weight of dry material and comprising two populations of particles with specific granulometric properties, is concentrated by eliminating a fraction of the aqueous phase in the liquid state, then the residual water is dried off. The dry material content of the concentrated latex is from 50 to 80% by weight, and the absolute difference between the dry material content of the latex before and after concentration is over 10% by weight.

Method of applying a binder having less than 0.5% water soluble

Aqueous latex base binder of a synthetic polymer for preparing aqueous compositions for coating paper and board for printing, having improved wet and dry tear strength. The content in the latex of hydrosoluble compounds dissolved in the aqueous phase is less than 0.5% by weight in relation to the polymer.
