Abstract

The invention discloses a multi-C-shaped high-hollowness bright fiber which comprises a plurality of fiber filaments annularly distributed around the center of the fiber in an equal-diameter mode, wherein every two fiber filaments are connected with each other, and each of the two fiber filaments is provided with a first cavity; a second cavity formed by the plurality of fiber yarn filaments annularly distributed in an equal-diameter mode is also formed in the center of the fiber; the cross section of each fiber filament is C-shaped; and the outer contour of the fiber is formed by connecting a plurality of arc lines end to end in a surrounding mode. According to the fiber and the preparation method thereof, a unique multi-cavity special-shaped section structure is formed by the fiber filaments which are formed by using a multi-C-shaped melt extrusion seam and annularly distributed around the center of the fiber in an equal-diameter mode, the hollowness can be up to 40-50%, the fabric has a better lightening effect, and gaps are formed between fibers formed by the hollow outlines and peripheral irregular outlines of the fibers, so that the light weight of the fiber is further improved, and the moisture absorption, air permeability and the anti-static performance of the fiber fabric are improved.

Description

technical field [0001] The invention relates to the field of fibers, in particular to a multi-C-shaped high-hollow bright light fiber and a preparation method thereof. Background technique [0002] Polyester and nylon are the most 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 wearing stuffy. In recent years, with the development of production technology and people's demand for clothing, the consumption has grown rapidly. China has become the largest producer and demand country of polyester chemical fiber. The development of production and demand is in line with 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 invention proposes a mult...
