(57) Abstract : This invention relates to improvements in heat
and moisture-shrink problems in polypropylene fibers. Such
fibers require the presence of compounds that quickly and
effectively provide rigidity to the fiber after heat-setting. These
compounds include structures that nucleate polymer crystals
within polypropylene after exposure to sufficient heat to melt
the polymer and allowing the melt to cool. The compounds must
nucleate polymer crystals at higher temperatures than the
polypropylene without the nucleating agent during cooling.
Thus, the "rigidifying" nucleator compounds provide nucleation
sites for polypropylene crystal growth. After drawing the
nucleated composition into fiber form (11), the fiber is exposed
to sufficient heat to grow the crystalline network (26), thus
holding the fiber in a desired position. The preferred
( Figure: 01 )
"rigidifying" compounds include dibenzylidene sorbitol based
compounds, as well as less
preferred compounds, such as sodium benzoate, certain sodium and lithium phosphate salts (such as sodium 2,2'methylene-bis-(4,6-di-tert-butylphenyl)phosphate).
