Abstract
An apparatus for dry-manufacturing recycled leather comprises air-laid material; and recycled leather manufactured using the apparatus for dry-manufacturing recycled leather. The apparatus for dry-manufacturing recycled leather molds leather fibers and general fibers, which are mixed using air-laid material, and thus a conventional carding process is not required, and recycled leather manufactured thereby has a high tensile strength.
Claims12
A dry manufacturing apparatus for recycled leather, comprising:
- a leather fiber separator configured to separate leather fibers from leather waste;
- a blender configured to blend the leather fibers with general fibers;
- and
- a molder configured to mold the leather fibers and general fibers to the recycled leather,
- wherein the molder has an airlaid machine configured to mold the leather fibers and general fibers,
- wherein the general fibers include filaments or staple fibers,
- wherein the airlaid machine has a plurality of airlaid machines, wherein upper portions of the plurality of airlaid machines are configured to be fed with the leather fibers and the general fibers that are blended, and lower portions of the plurality of airlaid machines are configured to mold the leather fibers and the general fibers that drop from the upper portions, and
- wherein the plurality of airlaid machines has air suppliers configured to blow air to the lower portions of the plurality of airlaid machines to allow a drop time of the leather fibers and the general fibers to be extended.
