FIBER FOR SUPPRESSING CRACK OF CURED BODY BASED ON HYDRAULIC COMPOSITION AND CURED BODY CONTAINING THE SAME
PROBLEM TO BE SOLVED: To provide a fiber for suppressing cracks of a cured body which can satisfactorily suppress cracks of a cured body based on a hydraulic composition and provides good workability of the hydraulic composition, and to provide a cured body containing the same.SOLUTION: A fiber for suppressing cracks of a cured body based on a hydraulic composition is formed from an ethylene-vinyl alcohol-based copolymer that has fineness of 0.5-50 dtex and an aspect ratio of 100-1,000, has a coefficient of water absorption of 0.1-20% and of which at least a part has an ethylene content of 25-70 mol%. Preferably, a fiber has an average fiber length of 1-50 mm. Preferably, a fiber has a hollow structure, where at least two thermoplastic resins form a sheath-core structure in a fiber direction, and a core component has a hollow structure.SELECTED DRAWING: None
【課題】水硬性組成物に基づく硬化体のひび割れを良好に抑制でき、かつ水硬性組成物の良好な施工性ももたらす硬化体ひび割れ抑制用繊維、およびそれを含む硬化体を提供。【解決手段】０．５〜５０ｄｔｅｘの繊度および１００〜１０００のアスペクト比を有し、吸水率は０．１〜２０％であり、少なくとも一部は２５〜７０ｍｏｌ％のエチレン含有量を有するエチレンビニルアルコール系共重合体からなる、水硬性組成物に基づく硬化体のひび割れを抑制するための繊維。好ましくは、１〜５０ｍｍの平均繊維長を有する繊維。好ましくは中空構造を有し、少なくとも２種の熱可塑性樹脂が繊維方向に芯鞘構造を形成し、芯成分は中空構造を有する繊維。【選択図】なし
