PROBLEM TO BE SOLVED: To provide a mesh sheet in a mesh fence for use in a marine fish preserve in which a crash contact influence on fish is reduced, adhesive properties and adhesion amount of marine lives such as shellfish and seaweed are reduced, it is easy to fall off naturally by own weight or raging waves in the stormy weather, hydraulic pressure resistance to the ocean current is low, and a construction load in the sea is reduced.SOLUTION: A mesh sheet has a large number of cavities using a coarse fabric as a base fabric and constituted of a swelling elastic material resin layer covering the front and back entire surface. The swelling elastic material resin layer contains a main component of gelatinous resin elastic materials and water absorbing resin particles in a dry mass ratio of 100:1 to 5:1. The water absorbing resin particles are coarsely dispersed in the gelatinous resin elastic materials and forms an exposed part of 25 μm to 500 μm in diameters.COPYRIGHT: (C)2016,JPO&INPIT【課題】海洋生簀に用いるメッシュ状フェンスに於いて、魚体への激突接触影響が少なく、貝類や海草類などの海洋生物の付着性及び付着量が少なく、自重や時化の荒波などにより自然に脱落し易いものであって、海流に対する水圧抵抗が低く、海中での設営負荷の少ないメッシュシートの提供。【解決手段】粗目織物を基布として、その表裏全面を被覆する膨潤性弾性体樹脂層とで構成された多数の空隙部を有するメッシュシートにおいて、膨潤性弾性体樹脂層が、ゲル状樹脂弾性体及び吸水性樹脂粒子とを乾燥質量比100:1~5:1とする主成分を含み、吸水性樹脂粒子がゲル状樹脂弾性体中に粗分散し、25μm~500μm径の露出部を形成するようにする。【選択図】図1
