Modified polyethylene, terephthalate for low temperature dyeability, controlled shrinkage characteristics and improved tensile properties

The modified polyethylene terepthalate is a copolymer formed from terephthalic acid or its ester, ethylene glycol, a flexible long chain aliphatic dicarboxylic acid or its ester, and a hydroxy terminated polyether polyol or acyclic diol or aliphatic diol. The modified polyethylene terephthalate fila...

Beschreibung
Zusammenfassung:	The modified polyethylene terepthalate is a copolymer formed from terephthalic acid or its ester, ethylene glycol, a flexible long chain aliphatic dicarboxylic acid or its ester, and a hydroxy terminated polyether polyol or acyclic diol or aliphatic diol. The modified polyethylene terephthalate filament, staple fiber, yarn and resultant fabric is dyeable with a disperse dye without dye carrier at low temperature of about 100° C. The dyed filament, staple fiber, yarn and resultant fabric has a dye index greater than 100, and preferably at least about 120 to 600 with controlled shrinkage of 6 to 10%.
