Claim:
1. A manufacturing method for fabrics with cut loop pile, the method characterized in that: a synthetic multifilament yarn having total fineness within the range from about 100 denier to about 300 denier is used as a core yarn; and a splittable-microfiber yarn having total fineness within the range from about 50 denier to about 300 denier and made of polyester and nylon is used as a covering yarn; and the method includes the steps of: a yarn manufacturing step for manufacturing a yarn having a structure of a core yarn where the covering yarn is fixed into through a heat treatment after twisting the covering yarn into said core yarn; a textile manufacturing step for knitting a textile using said yarn to include loop pile therein; a pre-fabric manufacturing step for manufacturing pre-fabrics having cut loops through raising and shearing of one surface or both surfaces of said textile; a fabric manufacturing step for manufacturing fabrics wherein the core yarns are outwardly protruded from the covering yarns at the section where said loops are being cut by splitting, weight reduction, and shrinking of said covering yarns through treatment of said pre-fabrics in an alkaline solution for about 30 minutes to about 60 minutes at about 100° C. to about 130° C. to produce soluble byproducts from the partial hydrolysis of the polyester of the covering yarns followed by washing the byproducts away; and a dyeing step wherein dyeing is performed on said fabric manufactured in said fabric manufacturing step for about 30 minutes to about 60 minutes at about 100° C. to about 130° C. followed by washing and drying to allow the cut section of the synthetic multifilament yarn, which is outwardly protruding from the section of the cut loops, to have a shape of a hook by being bent.
