Abstract

The invention discloses a multi-C-shaped high-cavity bright fiber. The fiber comprises a plurality of fiber filaments distributed around the center of the fiber with an equal diameter and an annular shape. The fiber filaments are all provided with a first cavity; the center of the fiber is also provided with a second cavity formed by a plurality of the fiber filaments with equal diameter annular distribution; the fiber filament has a C-shaped cross section; The outer contour of the fiber is formed by a plurality of arcs connected end to end; the present invention adopts the multi-C-shaped melt extrusion seam through the fiber filaments, and is distributed in an equal diameter ring around the center of the fiber, and the composition has a unique multi-dimensional structure. Cavity-shaped special-shaped cross-section structure, the hollowness can be as high as 40-50%, the fabric has a good lightening effect, the hollow outline of the fiber and the gap between the fibers formed by the surrounding irregular outline further improve the fiber's quality. Lightweight, and improves the moisture absorption, breathability and antistatic properties of fiber fabrics.

Description

technical field [0001] The invention relates to the field of fibers, in particular to a multi-C-shaped high-cavity bright fiber and a preparation method thereof. Background technique [0002] Polyester and nylon are the most widely used raw materials for clothing fabrics. Their fabrics have good wrinkle resistance and shape retention, but their fabrics are heavy, have poor moisture absorption and air permeability, and are prone to static electricity due to friction, making them stuffy. In recent years, with the development of production technology and people's demand for clothing, the amount of consumption has increased rapidly. China has become the country with the largest production and demand of polyester chemical fiber. The development of production and demand is related to people's pursuit of wearing comfort, light weight and aesthetics. The pursuit of asymmetry restricts its further development to a large extent. [0003] Based on the above situation, the present inve...
