    Abstract: The invention is a new Velcro-backed abrasive cloth. It is used in the coated abrasives industry. Its uniqueness is in the construction. It is formed by a cloth with Velcro on one side (1), after the cloth is dipped in resin, the side with no Velcro is coated with a layer of primer (2), and an abrasive layer (3) is then planted on top of the primer. On top of the abrasive layer, a multi-layer adhesive (4) is then planted. There is an anti clogging coating, an anti static coating or a combination of both on the multi-layer adhesive. This new Velcro backed abrasive cloth utilizes a napped fabric as the base material. The abrasives are directly planted onto the resin treated base material thus reducing the manufacturing steps and lowering costs. The unique construction of the base material extends the product lifetime and increases the sanding efficiency.
