SPINNING OIL COMPOSITION OF POLYESTER OR POLYAMIDE FIBER YARN

摘要

Spin finish compositions having as base oil polyether compounds which are omega -methoxy-poly (oxyethylene oxypropylene) ether derivatives of a specified type and containing 0.05 to 10 weight % of polyalkylene oxide modified polysiloxane of another specified type are particularly desirable for application to polyester and polyamide yams for ultra-high speed texturing because they have the characteristics of preventing fuzz on the yarns, thermally degraded substances and tacky white powder as well as reducing tackiness of such white powder.
