Abstract

The invention relates to the field of polyester processing, and in particular relates to a preparation method of polyester silk-like fabric and an adopted profiled fiber. According to the technical scheme, a profiled fiber monomer for preparing the polyester silk-like fabric comprises a matrix fiber and branch fibers, wherein the matrix fiber is hollow and is provided with at least three first arc-shaped notches; the branch fibers are arranged in the first arc-shaped notches; bulges are formed between the adjacent first arc-shaped notches; at least two second arc-shaped notches are arranged on the surface, facing the first arc-shaped notches, of each branch fiber; a first support part is formed between two adjacent second arc-shaped notches; a second support part is formed at the outer side of the second arc-shaped notch at the outermost side; the surface of each first arc-shaped notch on the back surface of each branch fiber sinks inwards to form a third arc-shaped notch; and the maximum distance between the axis of the matrix fiber and the bulges is greater than that between the axis of the matrix fiber and the branch fibers in the same cross section. The polyester silk-like fabric prepared by the method has good elasticity and breathability.

Description

technical field [0001] The invention relates to the field of polyester processing, in particular to a preparation method of polyester imitation silk fabric and the special-shaped fiber used. Background technique [0002] Prior art, such as the invention patent application with publication number CN1096333A, discloses a kind of three-iso polyester co-spun fine-denier filament imitation silk and its production process. Polyester low elastic yarn is used as weft yarn to weave fabric; however, the elasticity and air permeability of this kind of fabric are still not ideal. Contents of the invention [0003] The object of the present invention is to provide a special-shaped fiber monomer for preparing polyester imitation silk fabric. The special-shaped fiber prepared by using the special-shaped fiber monomer can make the polyester imitation silk fabric have good elasticity and air permeability. [0004] The above-mentioned technical purpose of the present invention is achieved ...
