Embodiment 1

[0013] Embodiment 1, sweat-conducting, moisture-permeable and breathable fiber

[0014] Raw material: polyethylene terephthalate (intrinsic viscosity 0.65-0.66, melting point 266°C, carboxyl content ≤ 25 equivalents / g x 106, ash content < 0.04%)

[0015] The polyethylene terephthalate was dried by a drum dryer (at a temperature of 150° C.), and then put into a VD406 short filament melt spinning machine for melt spinning. The raw material is melted at a temperature of 280°C, and then enters the screw extruder for extrusion (the temperature in the 1st zone of the screw is 260°C, the temperature in the 2nd zone of the screw is 270°C, the temperature in the 3rd zone of the screw is 272°C, and the temperature in the 4th zone of the screw is 278°C, the temperature in the 5th zone of the screw is 279°C, and the temperature in the 6th zone of the screw is 280°C), enter the spinning assembly through the melt pipe and spray out from the porous spinneret. image 3 Shown is the schematic...

Abstract

The invention discloses a breathable fiber with moisture penetrability and a preparation method thereof. The breathable fiber with moisture penetrability consists of three hollow fibers with circular arc cross section. The circular arcs are connected in such a way that every two are externally tangent to each other, and a closed region formed by mutual connection is an entity. The hollow fibers are made from polyethylene terephthalate with the intrinsic viscosity of 0.65-0.66, the melting point of 266 DEG C, the carboxyl content of more than zero and less than or equal to 25 equivalent / g *10<6>, and the ash content of more than zero and less than 0.04%. The breathable fiber with moisture penetrability is hollow fibers with three holes with three outward openings so as to be breathable and have moisture penetrability. When in hot rolling, a shape with six interlaced holes is formed between the adjacent fibers and has openings, thus the fiber has excellent moisture penetrability and is one of ideal filling materials.

Description

technical field [0001] The invention relates to perspiration-conducting, moisture-permeable, air-permeable fibers and a preparation method thereof. Background technique [0002] Hollow fiber is the abbreviation of chemical fiber with a cavity in the cross section along the axial direction, and is an important special-shaped fiber. There are also many kinds of fibers with a middle cavity in nature, such as kapok, polar bear hair, rabbit hair, cotton, etc. The appearance of hollow fiber is the result of the application of bionics. The cavity provides still air, which improves the warmth retention of the fiber and increases the surface area per unit volume, thereby improving the bulkiness of the fiber; The adsorption capacity of the fiber, as well as the ability to combine with the matrix material when used as a composite material, not only improves the stiffness and stiffness of the fiber to a certain extent, but also improves the bending resistance and wear resistance of the...
