  • Disperse dye-dyeable regenerated cellulose fiber and textile products containing the fiber
    Patent number: 5753367
    Abstract: Novel regenerated cellulose fiber dyeable with disperse dye is disclosed. In this regenerated cellulose fiber, 10 to 40 weight % of polyester fine particles or styrene-acrylic polymer fine particles having an average particle size of 0.05 to 5 .mu.m are compounded. Products wherein the regenerated cellulose fiber and polyester fiber are used in combination can give dyed products excellent in homochromatic properties, and since both fibers can be dyed at the same time, the dyeing efficiency is remarkably improved.
    Type: Grant
    Filed: October 27, 1995
    Date of Patent: May 19, 1998
