Abstract
Abstract Embossable foam latex compositions prepared by dispersing into a foam latex from 20 to 150 parts by weight per hundred parts of latex solids of a powdered particulate material having a melting point in the range 90 DEG to 200 DEG C. Embossing of foam-backed carpet or foam sheet material prepared from these latex compositions is readily accomplished by heating the foam structure to the melting temperature of the dispersed particulate material, then passing the foam through a cold embossing roll to chill and set the foam in place.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
81 words
A method for preparing embossed foam latex sheet consisting of a foamed styrene-butadiene elastomer latex having dispersed therein from 25 to 100 parts per hundred parts of latex solids of a powdered particulate solid having a softening temperature in the range 90°-200° C., said method comprising: heating said foamed latex sheet to a temperature sufficient to soften the particulate solid; and contacting said heated foamed latex sheet with a cold embossing roll to depress the foam and solidify the particulate solid.
Claim 2
Independent Claim
81 words
A method for preparing embossed foam latex sheet consisting of a foamed styrene-butadiene elastomer latex having dispersed therein from 25 to 100 parts per hundred parts of latex solids of a powdered particulate solid having a softening temperature in the range 90°-200° C., said method comprising: heating said foamed latex sheet to a temperature sufficient to soften the particulate solid; and contacting said heated foamed latex sheet with a cold embossing roll to depress the foam and solidify the particulate solid.
