MANUFACTURE OF AQUEOUS SUSPENSIONS OF POLYOLEFIN FIBRIDS |
摘要 |
<p>A process for the manufacture of non-foaming aqueous suspensions of polyolefin fibrids using suitable dispersing agents. These are obtained by polycondensation of 1 mole of melamine, from 1.8 to 3 moles of formaldehyde and from 0.1 to 0.5 molar portions of amino carboxylic acids or alkali metal salts thereof. Very small quantities of said dispersing agents are sufficient to finely disperse the hydrophobic polyolefin fibrids in water and to prevent the formation of foam in the manufacture of web structures of a paper-like and textile-like nature. The aqueous suspensions of polyolefin fibrids may also contain cellulose fibers.</p> |
