Package of polyurethane elastic yarn for heat bonding |
摘要 |
A package of polyurethane elastic yarn for heat bonding which weighs more than 1 kg and measures such that the diameter-to-width ratio is greater than 0.5 and which is obtained from polyurethane elastic yarn by giving it 3.0-10.0 wt % of a finishing agent and then winding it up, said finishing agent is polypropylene glycol-based polyol used alone or composed of component (A) which is a polypropylene glycol-based polyol and component (B) which is a reaction product of a polypropylene glycol-based polyol and an organic diisocyanate compound. The finishing agent contains component (B) in an amount less than 30 wt % and have an apparent viscosity of 50-250 mPa.s at 30° C. and a surface tension of 30-45 dyn/cm.
