WATER-DISINTEGRABLE COMPOSITE FIBER AND METHOD FOR PRODUCING THE SAME |
| 摘要 |
A water-disintegrable composite fiber comprising a phase containing a polyglycolic acid resin and a phase containing a polylactic acid resin with a D-lactic acid unit ratio of at least 1.0%; the two phases extending continuously in a lengthwise direction; and the composite fiber having a cross sectional area formed by the phase containing the polyglycolic acid resin having an area ration of at most 50%; and the content of the polyglycolic acid resin being from 2 to 100 parts by mass per 1 part by mass of the D-lactic acid units in the polylactic acid resin. |

1. A water-disintegrable composite fiber comprising a phase containing a polyglycolic acid resin and a phase containing a polylactic acid resin with a D-lactic acid unit ratio of at least 1.0%;
the two phases extending continuously in a lengthwise direction respectively; and the composite fiber having a cross-sectional area formed by the phase containing the polyglycolic acid resin having an area ratio of at most 50%; and the content of the polyglycolic acid resin being from 2 to 100 parts by mass per 1 part by mass of the D-lactic acid units in the polylactic acid resin. |
