A kind of composite short fiber includes the first component and the second component, wherein the first component (1) includes that a linear polyethylene has 0.90-0.The density and low density polyethylene (LDPE) of 94 grams per cubic centimters, the linear polyethylene that there is polyester of second component (2) containing 50 mass % or more fusing point to want high 40 °C of melt point above constitutes first assembly, the first assembly (1) constitutes the fiber at least 20% surface in the cross section of fiber, two elements are in this way, the position of the center of gravity made deviates from the position fiber of the center of gravity of the second component (2). This mode shows the petite person of crimpiness composite short fiber attack and crimps to be formed selected from wave-like curls shape and the production of helical form rolled form.
