    • A scouring material comprises a three-dimensional non-woven web of entangled fibres bonded to one another at their mutual contact points by a pre-bond resin and a plurality of abrasive particles are adhered to the fibres of the bonded web by a make-coat resin. A majority by weight of the fibres comprise natural fibres and the bonded web has a maximum density of 50 kg/m3. A method of making a scouring material comprises the steps of: 1) forming a three-dimensional nonwoven web of natural fibres contacted with dry particulate material that includes fusible binder particles, 2) exposing the web to conditions that cause the binder particles to form a flowable liquid binder, and then solidifying the liquid binder to form bonds between the fibres of the web and thereby provide a pre-bonded web and 3) applying abrasive particles to the pre-bonded web and bonding the abrasive particles to the fibres of the pre-bonded web by at least a make-coat resin to provide the scouring material.
    • 冲刷材料包括通过预结合树脂在它们的相互接触点处彼此结合的缠结纤维的三维非织造网,并且多个磨料颗粒通过涂层粘合到粘合纤维网的纤维上 树脂。 大部分纤维的重量包含天然纤维,粘合纤维网的最大密度为50kg / m 3。 制备洗涤材料的方法包括以下步骤:1)形成与包含可熔粘合剂颗粒的干燥颗粒材料接触的天然纤维的三维非织造纤维网,2)将纤维网暴露于导致粘合剂颗粒形成的条件 然后固化液体粘合剂,以在纤维网的纤维之间形成粘合,从而提供预粘合的纤维网,并且3)将磨料颗粒施加到预先粘合的纤维网上并将磨料颗粒粘结到预先粘合的纤维上 通过至少一种生衣涂层树脂来形成所述的冲洗材料。
