A polylactic acid composition comprising (A) a polylactic acid-series resin and (B) an acrylic triblock copolymer is prepared. The composition fulfills the following requirements: (1) the acrylic triblock copolymer (B) is a triblock polymer comprising (B1) a polymer block having a glass-transition temperature of not higher than 25&#xb0; C., (B2a) a polymer block which has a glass-transition temperature of not lower than 60&#xb0; C. and is bound to a terminal of the polymer block (B1), and (B2b) a polymer block which has a glass-transition temperature of not lower than 60&#xb0; C. and is bound to another terminal thereof; (2) the polymer block (B1) comprises a main structural unit derived from an acrylate, and the polymer block (B2a) and the polymer block (B2b) independently comprise a main structural unit derived from a methacrylate; and (3) both of the weight-average molecular weights of the polymer block (B2a) and polymer block (B2b) are smaller than the weight-average molecular weight of the polymer block (B1). The polylactic acid-series resin (A) and the acrylic triblock copolymer (B) may form a phase separation structure.

Polylactic acid composition

Disperse dye-dyeable regenerated cellulose fiber and textile products

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.
