Abstract
Artificial leather includes a non-woven fabric made of split type conjugate fibers and a resin material for submerging or coating the non-woven fabric. The conjugate fibers are made from a first polymer with crystallization of 40% to 95% and a second polymer with crystallization of 1% to 25% by conjugate spinning. Each of the conjugate fibers is split into 24 to 128 segments.
Claims
exact text as granted — not AI-modified1 . Artificial leather comprising a non-woven fabric made of split type conjugate fibers and a resin material for submerging or coating the non-woven fabric, wherein the conjugate fibers are made from a first polymer with crystallization of 40% to 95% and a second polymer with crystallization of 1% to 25% by conjugate spinning, and wherein each of the conjugate fibers is split into 24 to 128 segments.
2 . The method according to claim 21 wherein the fine fibers include a flat form with a length of 5 mm to 70 mm, a cross-sectional radial size of 2 μm to 25 μm and a cross-sectional transverse size of 0.5 μm to 8 μm.Cited by (0)
