POLYESTER RESIN COMPOSITION

摘要

This high contraction modified polyester composition enhances shrinkage tension. This polyester comprises: terephthalic acid and 5-20 wt.% isophthalic acid as difunctional carboxy acid; ethylene glycol as difunctional alcohol; and 0.5-3.0 wt.% glyceryl monostearate as a side chain forming agent. When spinning using this modified polyester, the high contraction polyester fiber whose max thermal shirinkage is above 0.6g/d can be obtained.
