Abstract
Description
Technical Field
[0001] This utility model relates to the field of fiber technology, specifically to a composite spiral fiber. Background Technology
[0002] Monofilaments are continuous fibers spun from molten synthetic resin through a single-hole spinneret. The raw material is typically synthetic resin, which is heated and melted to form a spinning melt. This melt is then continuously, quantitatively, and uniformly extruded through a single-hole spinneret. The extruded melt is cooled and solidified in air or in a specific coagulation bath, thus forming the monofilament.
[0003] The fibers used in existing brush bristles are usually straight fibers with a circular cross-section. The surface of a single straight fiber with a circular cross-section is smooth and has low surface roughness. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a composite spiral fiber that increases surface roughness.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a composite spiral fiber, comprising two or more fiber monofilaments of the same length co-extruded together, wherein the two or more fiber monofilaments are integrally formed into fibers with equal cross-sections, the cross-section of the fibers being centrally symmetrical or axially symmetrical, and the outer peripheral surface of the fibers having spiral-shaped protrusions, the spiral-shaped protrusions being referenced to the central axis of the fibers. The composite spiral fiber is formed as follows: the shape of the single-hole spinneret is set according to the specific cross-sectional shape of the composite spiral fiber, and multiple single-hole spinnerets of different shapes are combined to form the cross-sectional shape of the fiber. During the fiber extrusion process, the fiber that has not yet cooled and solidified is rotated, and after rotational forming, it is cooled and solidified to obtain composite spiral fibers with different cross-sectional shapes.
[0006] Preferably, the cross-section of the fiber is triangular, square, pentagonal, or hexagonal.
[0007] Preferably, the cross-section of the fiber is hexagonal.
[0008] Preferably, the cross-section of the fiber is two tangent circles or ellipses.
[0009] Preferably, the cross-section of the fiber is three tangent circles or ellipses.
[0010] Preferably, the cross-section of one or more of the fiber monofilaments is circular, elliptical, triangular or quadrilateral.
[0011] Compared with the prior art, this utility model has the following advantages: composite spiral fiber can mix fiber monofilaments of different shapes to form more varied fibers, increase the morphological diversity of fibers, and the surface of the spiral fiber forms an uneven undulation. At the same time, compared with straight fibers formed by single fiber monofilaments, its surface roughness is higher, which is more conducive to cleaning stains and reducing stain residue.
