Embodiment

[0020] Reference figure 1 with figure 2 , Install a cone 3 with spiral melt channel in the spinneret guide hole 2 of the spinneret 1 of the spinning machine; the cone with spiral melt channel is a solid cone structure; the spiral melt channel 4 is a four-helix structure ; The hook 9 on the cone facilitates removal and installation.

[0021] Install the cone 3 with spiral melt channel in the spinneret guide hole 2 of the spinneret 1 of the spinning machine for spinning single-component sheath-core fiber; the spinning melt 5 containing functional particles can pass The spiral melt channel 4 on the surface of the cone installed in the spinneret guide hole of the spinneret rotates and flows into the spinneret micro-hole 6 at high speed, and is sprayed and solidified into a single-component sheath-core fiber 7; due to the high-speed rotation of the melt The huge centrifugal force urges the functional particles in the spinning melt to gather to the edge and eject them through the spi...

Abstract

The invention provides a spinning method and device of a single-component sheath-core fiber. The spinning device comprises a spinneret plate with a spinneret orifice guide hole; a cone with a spiral smelting channel is installed in the spinneret orifice guide hole of the spinneret plate; the spiral melting channel on the side surface of the cone is of a single-spiral structure, or a double-spiral structure, a three-spiral structure, a four-spiral structure, or a multiple-spiral structure; and the spinneret end part of the spiral melting channel is connected with a spinneret micropore. The spinning method comprises the steps of feeding a spinning melt with functional particles into the spinneret micropore through the high-speed rotation and flowing of the spiral melting channel on the surface of the cone installed in the spinneret orifice guide hole of the spinneret plate, and then injecting and solidifying to obtain the single-component sheath-core fiber. The spinning method and device disclosed by the invention have the characteristics of simpler process and equipment, small energy consumption, low cost and good effect.

Description

Technical field [0001] The invention relates to a spinning method and device for a single-component sheath-core fiber, and belongs to the technical field of fiber manufacturing. Background technique [0002] With the improvement of people’s quality of life, the advent of some functional fibers and differentiated fibers has greatly improved the functions and properties of traditional fibers, such as antistatic, anti-ultraviolet, antibacterial, acaricide, physical therapy, humidity control, etc. While beautifying people's clothing, it has a positive meaning for promoting physical fitness and improving the quality of physical health. At this stage, the research on fiber modification is becoming more and more mature. The general method of making functional fibers is to add functional particles to the spinning melt to spin. In order to ensure the functionality of the fiber, it is necessary to add enough functional particles, but this causes the fiber strength and elongation to decrea...
