Title:
SPINNING LUBRICANT FOR SYNTHETIC FIBER
Document Type and Number:
Japanese Patent JP2003013363
Kind Code:
A
Abstract:

To provide a spinning lubricant for synthetic fiber, directly (without dilution) oilable onto the fiber with favorable pickup, having high heat resistance and capable of giving high-quality yarn in smooth yarn manufacturing process.

This spinning lubricant for synthetic fiber comprises (A) a viscosity index-improving agent, (B) a lubricant and as necessary, (C) another component. The dynamic viscosity of this spinning lubricant is characterized in meeting the formulas (1) and (2) described below: V1/V2=0.5-3.0...(1) V1≤200...(2) (where, V1 is the dynamic viscosity at 25°C (mm2/s); and V2 is the dynamic viscosity at 200°C (mm2/s)).
