IMPROVING COMFORT BY MIXING DENIERS

摘要

Comfort properties of fibers of longitudinally-grooved fibers of scalloped-oval cross section are improved by providing such fibers as a mixture of different dpf and using a cationic-dyeable alkali metal sulfonate isophthalate salt copolyester that is also modified with a chain-brancher so that the filaments of different dpf can be drawn simultaneously.
