Abstract
Provided is leather fibers for use in yarn. The leather fibers forming the yarn are obtained from cowhide and a thickness index (M) of the leather fibers satisfies Equation 1: M=D1/D2≤60 [Equation 1] where D1: average thickness of the 10 fibers having the highest thickness in 1 mg of leather fibers, and D2: average thickness of the 10 fibers having the lowest thickness in 1 mg of leather fibers.
Claims1
A bundle of leather fibers obtained from cowhide and satisfying:
- M=D1/D2≤60 where D1:
- average thickness of the 10 fibers having the highest thickness in 1 mg of leather fibers, and D2:
- average thickness of the 10 fibers having the lowest thickness in 1 mg of leather fibers,
- wherein 30 wt % or more of the leather fibers have a thickness of 100 to 200 μm, and 30 wt % or more of the leather fibers have an H value of 30 or more, and
- wherein the H value is defined as follows:
- H=leather fiber length/leather fiber thickness.
