A majority by weight of the fibres comprise natural fibres and thebonded web has a maximum density of 50 kg/m3. A method of making a scouringmaterial comprises the steps of: 1) forming a three-dimensional nonwoven web of naturalfibres 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 liquidbinder, and then solidifying the liquid binder to form bonds between the fibres of theweb 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 byat least a make-coat resin to provide the scouring material.申请人：3M INNOVATIVE PROPERTIES CO地址：US国籍：US代理机构：Hill, Cecilia Ann更多信息请下载全文后查看
