This specification relates to a solution for overcoming the problem of loose loops formed by cutting the abrasive products. A method of obtaining an abrasive product () is provided. The method comprises providing a substrate () having a first surface () and a second surface (), providing abrasives () on the first surface () of the substrate and providing loops () on the second surface () of the substrate. The method further comprises providing a melted and/or burnt area () on the second surface () of the substrate by melting and/or burning the loops, and cutting the substrate () in order to provide the abrasive product (). Further, the abrasive product () is provided.

Abrasive product

An abrasive belt is provided which comprises a textile fabric being formed of interconnected yarns, and a coherent abrasive area formed on one side of the textile fabric, wherein the abrasive belt further comprises a plurality of regularly distributed openings in the form of through holes. The abrasive belt allows for a homogenous distribution of the abrasive material and thus an even sanding finish as well as for an appropriate dust removal and appropriate mechanical properties.

Abrasive belt grinding product

Provided is a flexible abrasive product () comprising a knitted cloth () on a first side of the flexible abrasive product (), grinding agents () applied on a second side of the flexible abrasive product () facing the first side, and a plurality of loops () protruding from the cloth () and from the first side, each loop () being formed by a pair of bottom-half arcs () connected by a protruding head () and the loops () being arranged in rows extending in the wale direction (W) of the cloth (), wherein the bottom-half arcs () are interlaced in the cloth (), and the protruding heads () of the loops () are interconnected with one another outside of the cloth () so as to form rows () of interconnected loops (), which rows () extend in the wale direction (W) of the cloth ().

A method of manufacturing a flexible grinding product comprises the steps: a) preparing an open cloth of knitted or woven fabric; b) applying a coating to one surface of the cloth, wherein the coated surface of the cloth has one or more flat portions; c) applying a grinding agent to the coated surface of the cloth. Further, a flexible grinding product has an open cloth, wherein a surface of the cloth is provided with a coating such that the coated surface has one or more flat areas which are at least partially provided with a grinding agent.
