(57) [abstract] (with correction) [Problem] To provide a practically sufficient mechanical strength and durability that can be used as a rotary blade for a mowing machine, and that can be used. A biodegradable monofilament having excellent processability is provided. The biodegradable resin (A) is mainly composed of an aliphatic polyester (B) resin or a monofilament for a mowing machine mainly composed of a lactic acid component, or a mixture of mainly an aliphatic polyester (B) and a plasticizer (C), or mainly a fat. Graft polymer obtained by further crosslinking a mixture of aliphatic polyester (B) and plasticizer (C), or plasticizer (C) A monofilament for a mower, containing 5 to 40% by weight of Monofilament for a mower, comprising a mixture in which a biodegradable resin (A) contains a filler component (D), a filler component (D) Is a monofilament for a mower, comprising a fibrous filler having an aspect ratio of 5 or more and / or a surface treatment with a silane coupling agent and an aspect ratio of 5 or more. |
