ABSTRACT:
Spin finish concentrate composition and the oil-in-water emulsion made from the concentrate for application for conventional speed or high speed melt spinning processes for producing polyester or polyamide yarns, consists essentially of oil lubricant component, pentaerythritol ester lubricant, ethoxylated sorbitan monooleate of HLB ranging from 6 to 15, anionic antistatic agent, water soluble sulfosuccinate wetting agent, and oil soluble ethoxylated polymethylsiloxane wetting agent having molecular weight of 400 to 700 and an aqueous surface tension value of less than 21 dynes/cm. The concentrate has long term stability. The finish prepared from the concentrate produces excellent quality yarn with virtually no broken filaments, and leaves no deposits on heated draw rolls, relaxation rolls and any yarn guides during spinning and drawing operations.
