Disclosed are a method for preparing spun leather yarn using leather fiber, and spun leather yarn prepared according to the preparation method. The spun leather yarn prepared according to the preparation method enables the manufacture of fabrics, knitted goods, and lace goods, which have the character of leather, and thus can be effectively used for various fashion applications. In addition, the spun leather yarn can replace existing leather materials, which have been used in bags, athletic shoes, and the like, and thus is not affected by material supply in accordance with seasonal changes, and accordingly, the economic effect thereof is excellent. Moreover, the spun leather yarn has warmth retention and general flame retardancy, which are the properties of natural leather, and thus is of very high quality.

A fiber processing device includes a drum having a plurality of openings on an outer peripheral surface, sieving a raw material containing fibers, and configured to rotate about a rotation axis, a housing that supports the drum, a guide portion (convex portion) provided on an outer peripheral surface of the drum; and a restriction portion (bearing) that restricts movement of the drum in a direction of the rotation axis by contacting the convex portion. At least one of the restriction portion and the guide portion is configured to rotate about an axis (rotation axis) orthogonal to the rotation axis.

A process of manufacturing a resilient, fibrous, piled woven fabric includes moving a resilient, fibrous woven fabric through a platform type carding machine including at least one first roller having a rough surface, at least one second roller having a surface formed of needles, and at least one third roller having a fine surface. One surface of the woven fabric passes and contacts the first roller so that fibers on one surface of the woven fabric are cut, one surface of the woven fabric passes and contacts the second roller so that the fibers on one surface of the woven fabric are broken to form a layer of uneven pile structure thereon, and one surface of the woven fabric passes and contacts the at least one third roller so that the layer of uneven pile structure is combed out and smoothed to finish a resilient, fibrous, piled woven fabric.
