Abstract: A method of manufacturing a fleece having different kinds of fibers in the front and back faces includes the steps of: weaving an extra-fine polyester fiber or acrylic fiber in a high gauge to have dense loops to form the front face of loop piles (1), and weaving a natural fiber such as cotton or silk as a ground yarn (2) of the back face; cutting the tip parts of the loop piles (1) formed in the weaving step so as to form cut piles (3); raising the cut piles (3) so as to form a raised fiber group (4); trimming the raised fiber group (4); causing pilling (5) in the raised fiber group (4) trimmed, by a contact friction; trimming the raised fiber group (4) at least once so as to form short raised fiber group (4).
