Polylactic acid fiber, method for producing the same, and fiber product |
| abstract |
【Task】 The present invention is intended to provide a polylactic acid fiber that is excellent in high-order process passability and that is particularly suitable for a knitted fabric composed of a knot portion and a hook portion. [Solution] The polylactic acid fiber of the present invention is a polylactic acid fiber having a knot elongation of 75 to 110% of the linear elongation and a knot strength of 75 to 100% of the linear strength. After melting 0 to 200 ppm of polylactic acid resin at a temperature of melting point + 60 ° C. to melting point + 90 ° C. and extruding from the die, the distance between the die surface and the cooling bath liquid surface is 1 to 10 cm at a take-off speed of 10 to 30 m / min. After cooling in a certain cooling tank, the film is stretched and then subjected to a relaxation treatment of 0 to 3%, and then the second stage relaxation treatment is performed at a relaxation rate of 0 to 10 in two or more heat setting regions having different temperatures. % In the range.
