| 摘要 |
The invention is directed to LCP monofilaments and yarn made therefrom which have improved adhesion properties, said monofilaments, and yarn made therefrom, comprising a liquid crystalline polymer filament having a finish selected from the group consisting of esters formed between (a) pentaerythritol and saturated polyols of up to 10 carbon atoms and 2 to 6 hydroxyl groups, and (b) a carboxylic acid of formula CxH2x=1COOH, wherein x is from 2 to 20, and wherein 2 to 6 of the hydroxy functions are convened to ester functions. In a preferred embodiment of the invention the finish is an ester formed from the reaction of pentaerythritol and a carboxylic acid of formula CxH2x=1COOH, wherein x is from 2 to 20, and preferably between 14 and 20. The most preferred esters are pentaerythritol tetrapelargonate and pentaerythritol tetraisostearate. |
