Embodiment 1

[0043] The dried polyester chips are heated and extruded to be melted with a screw, the temperature of the screw is 280° C., and the rotation speed is 100 rpm. The melt is sent to each spinning position of the spinning box, and is accurately metered and filtered by the metering pump, and then sprayed out from the spinneret. The diameter of the spinneret holes was 100 μm. After the thin stream of melt is sprayed out, it is cooled and solidified into filaments by the cooling air flow. There is one hole in the cross-section of the fiber, and the opening size of the hole on the fiber surface is 40-60 μm, that is, the feeding gap of the special-shaped hole of the spinneret is set at 40-60 μm. The silver ion antibacterial agent with an average particle size of 20-30 μm is used as a functional substance, and the spinning machine oil with a content of 10 wt % of the functional substance is prepared after being dispersed by ultrasonic vibration. After the solidified filaments are wet...

Embodiment 3

[0055] The dried polyester chips are heated and extruded to be melted with a screw, the temperature of the screw is 280° C., and the rotation speed is 100 rpm. The melt is sent to each spinning position of the spinning box, and is accurately metered and filtered by the metering pump, and then sprayed out from the spinneret. The diameter of the spinneret holes was 150 μm. After the thin stream of melt is sprayed out, it is cooled and solidified into filaments by the cooling air flow. There are 2 holes in the cross-section of the fiber, and the opening size of the holes on the fiber surface is 30-50 μm, that is, the feeding gap of the special-shaped hole of the spinneret is set at 30-50 μm. The tourmaline negative ion powder with an average particle size of 15-20 μm is used as a functional substance, and the spinning machine oil with a content of 12 wt % of the functional substance is prepared after surface modification and dispersion. When spinning filaments, the filaments ar...

Abstract

The invention discloses a functional fiber, a manufacturing method of the functional fiber and fabric formed via weaving functional fibers. The function fiber comprises a fiber body, a through hole and a plurality of functional substances, the through hole is arranged in the fiber body along the axial direction, an opening is formed on the surface of the fiber body, and the width of the opening is D1; the diameter of the functional substances is D90, and the functional substances are filled in the through hole; and D1 is less than the diameter D90. Since the fiber body of the functional fiberis provided with a through hole structure in the axial direction, the specific surface area and porosity are large, and more functional substances can be accommodated. Moreover, the functional substances are ''packaged'' in the through hole and have higher functional activity and better effects.

Description

technical field [0001] The invention relates to the field of textile science, in particular to a functional fiber, a manufacturing method thereof, and a fabric woven by the functional fiber. Background technique [0002] Functional fiber refers to a new type of fiber that has some special function in addition to the physical and mechanical properties of ordinary fibers. The emergence of functional fibers is a revolutionary symbol of material science, and its development and progress have promoted the leap from traditional textile industry to high-tech industry. Functional fibers have special properties in physics, chemistry, medicine and biology, and have been widely used in many fields. In terms of physical functions, it includes electrical functions such as antistatic, electrical conductivity, and electromagnetic wave shielding; in terms of thermal functions, it has high / low temperature resistance, heat insulation, flame retardancy, heat sensitivity, heat storage, etc.; o...
