摘要
PROBLEM TO BE SOLVED: To provide a degradable nonwoven fabric having an easily controllable degradation rate, and good mechanical strengths; and to provide a farm material and a weed-preventing sheet obtained by using the nonwoven fabric.;SOLUTION: The nonwoven fabric is composed of a core-sheath type conjugate fiber constituted of a core part and a sheath part. The polymer forming the core part contains a photodegradable polymer, and the polymer forming the sheath part contains a pigment. The weight ratio of the core to the sheath is regulated so as to be (90/10)-(10/90).;COPYRIGHT: (C)2005,JPO&NCIPI
