A fiber article having excellent hydrolysis resistance, characterizednin that the article is fiber structure composed of 10 to 90 % by weight of anfiber (A) comprised of a biodegradable plastic formulated with ancarbodiimide compound as a stabilizer against hydrolysis and 90 to 10 % bynweight of at least one fiber (B) selected from a natural fiber, a regeneratednfiber, a semi-synthetic fiber and a synthetic fiber, which fiber structure hasnbeen subjected to at least one treatment processing selected from scouringnprocessing, bleaching processing, liquid ammonium processing,nmercerization processing, biological processing, dyeing processing, or resinntreatment, and concentration of total terminal carboxyl groups derived fromnthe fiber (A) in said fiber article is not higher than 30 equivalents/ton basednon the fiber (A), etc. It is an object of the present invention to solvenconventional problems of a fiber or a fiber article comprising anbiodegradable plastic, such as poor hydrolysis resistance, poor heatnresistance, strength reduction and coloring by yellowing, and in particularnto provide a fiber article superior in hydrolysis resistance, alkali resistancenand dyeing resistance. |
