<p>A polylactic acid resin suitable for use especially in textile products; textile products obtained from the resin as a raw material (a fiber, multifilament, monofilament, staple, false-twist yarn, long-fiber nonwoven fabric, etc.); and processes for producing these textile products. The polylactic acid resin is a resin consisting mainly of a polylactic acid and is characterized in that it is linear, has an L-isomer content of 95 mol% or higher, an Sn content of 30 ppm or lower, a monomer content of 0.5 wt.% or lower, and has a relative viscosity of 2.7 to 3.9 or has a weight-average molecular weight of 120,000 to 220,000 and a number-average molecular weight of 60,000 to 110,000. The textile products each comprises the polylactic acid resin as the main material. The textile products each comprises a polylactic acid excellent in processability and fiber properties and free from problems in practical use.</p> |
