Abstract

The invention relates to a functional ramie fiber fabric and a preparation method. The functional ramie fiber fabric comprises following components including ramie fiber, polyester fibers, natural bamboo fiber and colored cotton fiber, wherein the polyester fibers are sheath-core composite polyester fibers, each sheath-core composite polyester fiber comprises a sheath layer and a core layer, eachcore layer has a circular cross section and is covered with the corresponding sheath layer, each sheath layer comprises PET polyester and first polyester masterbatches, and each core layer comprises PET polyester and second polyester masterbatches; the first polyester masterbatches are obtained by mixing and granulating first powder and polyester slices, and the second polyester masterbatches areobtained by mixing and granulating second powder and the polyester slices.

Description

technical field [0001] The present application relates to the technical field of fabrics, in particular to a functional hemp fiber fabric and a preparation method thereof. Background technique [0002] In modern social life, the role of clothing is far more than cold and warm, but requires multiple functions and performances, especially moisture absorption, breathability, antibacterial, skin-friendly, etc., which can improve people's wear health indicators. [0003] Hemp fiber is a moisturizing fiber taken from plant stems or leaves. It has good strength and is a natural cellulose fiber. It has the advantages of fast moisture absorption and dehumidification, and good air permeability. However, the elongation of the hemp fiber is small, the cohesion force is small, and the stiffness of the fiber is relatively large, so it is difficult to spin, and the short fleece with high rigidity produced by spinning is prone to itching. Due to the limitations of single fabric fibers in ...
