Summary: | PROBLEM TO BE SOLVED: To provide a fiber having indispensable performances for an injection fluid such as adding transportation of a proppant, dispersibility and dispersion stability and having controlled hydrolysis resistance with being decomposed and water solubilized quickly after functioning for a certain term in hot water at high temperature.SOLUTION: There is provided a fiber having straightness after 2 hours in hot water at 175°C of 50% or more and weight of non-water soluble component derived from the fiber after 48 hours in hot water at 175°C of 20% or less.SELECTED DRAWING: None
【課題】 プロパントの運搬、分散性、分散安定性を付与するという圧入流体に不可欠な性能を備えているとともに、高温の熱水中で一定期間機能した後、速やかに分解・水溶化する耐加水分解性がコントロールされた繊維を提供すること。【解決手段】 175℃の熱水中2時間後の直線度が50%以上であり、175℃の熱水中において48時間後の繊維由来の非水溶分の重量が20%以下である、繊維。【選択図】なし |
