Process for preparing an aqueous latex binder for manufacturing nonwovens employing ultrafiltration to form a latex having low hydrosolubles

摘要

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.
