  • Patent number: 9683319
    Abstract: The present invention provides fabrics with cut loop pile comprising a rayon core yarn and covering yarn of a split microfiber yarn and a manufacturing method thereof. The rayon core yarn at the section where said loops are cut is outwardly protruded from the covering yarn, wherein the rayon core yarn is separated into multiple filaments to function as hooks. The fabrics with cut loop pile show superior characteristics in polishing properties, sliding properties, water absorption properties, rapid drying properties and feeling of touch since polishing can be performed while easily catching foreign substances such as extremely minute dust particles or human hairs and the like by the hook-shaped rayon core yarn. Thus the fabrics with cut loop pile according to the present invention can be used usefully in products such as various kind of mats, towels, bathroom products, and the like including dishcloths and mops.
