Abstract
Finish compositions and methods for the manufacture of synthetic fibers and/or fabrics comprise hydrophobic esters of pentaerythritol homologs, such as hydrophobic pentaerythritol ester, as lubricants. These esters may be used by themselves or in conjunction with antistatic agents and/or other lubricants and permit the obtaining of high-strength nonwoven materials with increased production plant line speed and productivity. The finish may be used with a variety of fibers and fabrics.
Claims73
An essentially hydrophobic polyolefin-containing fiber including a coating comprising at least one ester of pentaerythritol homolog comprising at least one hydrophobic ester of pentaerythritol homolog dimer.
An essentially hydrophobic polyolefin-containing fiber including a coating comprising:
- (a) at least one mono-pentaerythritol ester and at least one di-pentaerythritol ester comprising substituents independently selected from the group consisting of C.sub.5 -C.sub.10 alkyl groups, said di-pentaerythritol ester being present in the range of about 1-90% by weight of total pentaerythritol ester;
- and
- (b) at least one antistatic agent.
A method of producing substantially hydrophobic polyolefin-containing fiber comprising applying to polyolefin-containing fiber an essentially hydrophobic composition comprising at least one ester of pentaerythritol homolog comprising at least one hydrophobic ester of pentaerythritol homolog dimer.
