Synthetic fiber with natural material blend, preparation method thereof and textile

Abstract

The invention relates to a synthetic fiber with a natural material blend, a preparation method thereof and a textile. The volume content of the natural material in the resulting volume of the synthetic fiber (1) is 0.5% to 45%. According to the invention, the natural material is ground in the form of particles (2) having an irregular shape, differing in length and width, the length (L) of the particles (2) of the natural material being 10% to 120% of the diameter of the synthetic fiber (1) and the width (W) of the particles being 25% to 75% of the length (L) of the particles (2). Meanwhile, the width (W) of the particles (2) does not exceed 50% of the cross-sectional diameter (D) of the synthetic fiber (1).
