Abstract
A fiber article having excellent hydrolysis resistance, characterized in that the article is fiber structure composed of 10 to 90% by weight of a fiber (A) comprised of a biodegradable plastic formulated with a carbodiimide compound as a stabilizer against hydrolysis and 90 to 10% by weight of at least one fiber (B) selected from a natural fiber, a regenerated fiber, a semi-synthetic fiber and a synthetic fiber, which fiber structure has been subjected to at least one treatment processing selected from scouring processing, bleaching processing, liquid ammonium processing, mercerization processing, biological processing, dyeing processing, or resin treatment, and concentration of total terminal carboxyl groups derived from the fiber (A) in said fiber article is not higher than 30 equivalents/ton based on the fiber (A), etc. It is an object of the present invention to solve conventional problems of a fiber or a fiber article comprising a biodegradable plastic, such as poor hydrolysis resistance, poor heat resistance, strength reduction and coloring by yellowing, and in particular to provide a fiber article superior in hydrolysis resistance, alkali resistance and dyeing resistance.
