A napped leather-like sheet is used that includes a fiber base material including a non-woven fabric of ultrafine fibers and an elastic polymer, wherein the napped leather-like sheet has a surface including a napped region including the ultrafine fibers that have been napped, and a plurality of unnapped regions including the ultrafine fibers that have been thermally welded and laid down, the unnapped regions being surrounded by the napped region and present discontinuously, a total area of the unnapped regions accounts for 5 to 30% of an area of the surface, and Y/X is 0.7 to 1.5, where X represents an average nap length of the napped ultrafine fibers and Y represents an overall average length of averages of widths, orthogonal to a longitudinal direction, of the unnapped regions.

The present invention relates to a pile fabric including an acrylic synthetic fiber at a napped portion, the acrylic synthetic fiber is obtained by spinning a spinning solution including 90 to 99 parts by weight of a polymer A and 1 to 10 parts by weight of a polymer B. The polymer A is a polymer obtained by polymerizing a composition A including 40 to 97 wt % of acrylonitrile, 0 to 5 wt % of a sulfonic acid-containing monomer and 3 to 60 wt % of another copolymerizable monomer. The polymer B is obtained by polymerizing a composition B including 0 to 70 wt % of acrylonitrile, 20 to 90 wt % of acrylic ester and 10 to 40 wt % of a sulfonic acid-containing monomer, and the polymer B is a polymer to be dissolved in a mixed solvent composed of water and at least one organic solvent selected from the group consisting of N,N-dimethylformamide, N,N-dimethylacetamide, dimethylsulfoxide and acetone. The acrylic synthetic fiber forming the napped portion is dyed or discharge-printed at least partially, and the dyed or discharge-printed acrylic synthetic fiber has an apparent specific gravity in a range of 0.8 to 1.1.

A device used for felting. The felting device may include a top portion and a bottom portion. The bottom portion may include a bottom surface with a waffle maker pattern. The waffle maker pattern may include a plurality of intersecting grooves that form protruding blocks. The top portion may include a handle for easily grasping and using the felting device.

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.

The present invention provides fabrics with cut loop pile comprising a synthetic filament core yarn and covering yarn of a split microfiber yarn and a viscose rayon yarn and a manufacturing method thereof. The core yarn at the section where said loops are cut is outwardly protruded from the covering yarn, wherein the synthetic multifilament 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 owing to the split yarn of microfibers and the viscose rayon yarn which comprises the covering yarn, and 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 multifilaments of the 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.
