Abstract

Le but de l'invention est de fournir un matériau de protection. Pour ce faire, la présente invention propose un matériau de protection anti-lacération caractérisé en ce qu'il présente une partie revers comportant une fibre haute résistance. De plus, la présente invention propose un équipement anti-lacération destiné à être utilisé par un opérateur de scie à chaîne et utilisant le matériau de protection anti-lacération. Selon la présente invention, la partie revers comportant une fibre haute résistance permet que la longueur par brin de fibre haute résistance soit suffisamment longue, et il y aura un grand volume de fibres qui sera emmêlé et extrait par une lame rotative à l'instant où la lame entre en contact avec celle-ci, ce qui permet que la lame rotative soit arrêtée plus tôt que dans l'état de la technique et ce qui empêche toute lésion.
