Zusammenfassung:To provide a biodegradable fiber product suitable as material for filter cloth, filter, strainer, and screen.SOLUTION: A biodegradable fiber product is constituted by applying heat treatment to a gray fabric that is a woven fabric on which a long fiber filament having single fiber fineness of 15 dtex or more and 50 dtex or less, the number of component single fiber of one or more and five or less, and total fineness of 15 dtex or more and 150 dtex or less is used for at least either one of warp or weft. The long fiber filament is composed of polylactic acid polymer. The biodegradable fiber product has a maximum heat shrinkage development temperature TSmax of 80°C or more and 100°C or less in heat shrinkage stress measurement and a maximum heat shrinkage stress value σmax at the maximum heat shrinkage development temperature of 0.05 cN/dtex or more and 0.20 cN/dtex or less.SELECTED DRAWING: None 【課題】濾過布、フィルター、ストレーナ、スクリーン用の材料として好適な生分解性繊維製品を提供する。【解決手段】単糸繊度が15dtex以上50dtex以下、構成単糸本数が1本以上5本以下、総繊度が15dtex150dtex以下の長繊維フィラメントを経糸および緯糸の少なくとも一方に配する織物である生機を熱処理して構成される生分解性繊維製品であって、長繊維フィラメントは、ポリ乳酸重合体によって構成されており、熱収縮応力測定における最大熱収縮発現温度TSmaxが80℃以上100℃以下であり、最大熱収縮発現温度での最大熱収縮応力値σmaxが0.05cN/dtex以上0.20cN/dtex以下であることを特徴とする生分解性繊維製品。【選択図】なし
