Embodiment

[0045] The core fiber 19 is made of 40 counts of pure cotton yarn, and its fiber diameter ranges from 7 to 15 μm; the outer layer fiber 18 is made of electrospun polyacrylonitrile (PAN) nanofibers, and its fiber diameter ranges from 0.3 to 0.5 μm. The average degree of orientation of its fibers is 15°.

[0046] The thickness of the yarn 8 is 453 μm, and the average distance between the fibers is 9.7 μm; the thickness of the nanofibers 14 outside the yarn 8 is 15.6 μm, and the average distance between the fibers is 0.3 μm.

[0047] Cotton fiber has good hydrophilicity and hygroscopicity, but it cannot conduct moisture well, so that the cotton fiber fabric will stick to the skin after being soaked in sweat, causing discomfort.

[0048] Electrospun PAN nanofibers are hydrophobic fibers, and the nano-effect endowed by the nanoscale enables the water on the surface to spread rapidly along the nanofiber axis, which is conducive to the evaporation of water.

[0049] The combination of...

Abstract

The invention discloses a bionic moisture-permeable and sweat-discharge yarn and a preparation device and method thereof. The moisture-permeable and sweat-discharge yarn is internally provided with a tree-shaped cross network channel for simulating an internal water conveying channel of a plant. The preparation device comprises an insulating conical cover, and air nozzles are symmetrically arranged on the two sides of the inner wall of the insulating conical cover; a metal rod with a metal circular ring at one end is arranged on the lower portion of each air nozzle, and an electrostatic spinning sprayer is arranged below each metal circular ring. The preparation method comprises the steps that yarns of core layer fibers penetrate through the center from the bottom of the insulating conical cover to the top of the insulating conical cover, and air in the insulating conical cover spirally moves along the inner wall at a high speed to drive electrostatic spinning nanofibers to move spirally, so that the yarns are wrapped with the nanofibers, and the prepared moisture-permeable and sweat-discharge yarns are exposed from the top of the insulating conical cover. The water guiding channel in the plant is simulated, the pressure difference formed due to different sizes of the gaps of the surface and inner layers is used for generating the differential effect, the moisture guiding capability is obviously enhanced, and the one-way moisture guiding capacity is achieved.

Description

technical field [0001] The invention relates to a bionics-based moisture-conducting and sweat-wicking yarn and a preparation device and method thereof, belonging to the technical fields of electrostatic spinning and textiles. Background technique [0002] The moisture-wicking and sweat-wicking performance of fiber yarn directly affects the wearing comfort of the fabric. At present, natural hydrophilic fibers are often used as fabrics for close-fitting wear, but this type of fiber has the defect of moisture absorption and moisture conductivity, and will stick to the surface of the skin. Discomfort. In order to improve this defect, based on the principle of bionics, the water transfer channel inside the plant is simulated, and the moisture-wicking yarn is designed. [0003] Through the research on the mechanism of water transfer in plants, it is found that the absorption and transport of liquid water in plants is related to its structure and the pressure gradient formed by wa...
