Abrasive scouring pad

TLDR: A scouring pad is a solid cleaning composition 6 enclosed in an envelope 4 which forms a barrier layer 4 between the cleaning composition and an abrasive element 2, the barrier layer being of material that contains voids and the abrasive elements being an open structured web formed of non-absorbent and non-matting synthetic fibres which are resistant to abrasion and water, the fibres being held in random arrangement to form a non- woven, lofty, three-dimensional structure as mentioned in this paper.

A scouring pad comprises a solid cleaning composition 6 enclosed in envelope 4 which forms a barrier layer 4 between the cleaning composition and an abrasive element 2, the barrier layer 4 being of material that contains voids and the abrasive element being an open structured web formed of non-absorbent and non- matting synthetic fibres which are resistant to abrasion and water, the fibres being held in random arrangement to form a non- woven, lofty, three-dimensional structure. The abrasive element 2 which may surround the barrier layer 4 and may be attached thereto may comprise fibres of polyamide polyester, polypropylene, rayon cellulose acetate and nylon &c. and abrasive particles such as silicon carbide, alumina, carborundum, felspar or china clay may be dispersed on or in the element 2. The barrier layer 4 may be of natural or synthetic foam, cellular foam, woven, knitted or non-woven fabrics and the cleaning composition may be a soap or non- soap detergent. The edges of the barrier layer 4 and abrasive element 2 may be heat sealed or adhered together. The pad may be provided with a coating of rapidly dissolving soap on the abrasive element 2 or the outer surface of the barrier layer 4 and also with a layer of foam material between the barrier layer 4 and abrasive element 2.
