Description

Technical Field

[0001] The utility model relates to the technical field of multifilament yarns, belongs to the technical field of textiles, and specifically relates to a matte spandex multifilament yarn. Background Art

[0002] Covered yarn is a new fiber formed by covering another fiber with one fiber, such as silk / spandex covered yarn, etc. Spandex has good elasticity but poor wear resistance, so when it is used, spandex is used as the core yarn, and the spandex filament is covered with short fiber yarn. The elastic fabric woven with it has the advantages of comfort, fit, and strong elasticity. With the continuous development of science and technology, spandex covered yarn is a stretch yarn formed by covering the stretched spandex filament in a spiral shape with filament or short fiber yarn as the core.

[0003] Moreover, with the demand for existing elastic fabrics, the demand for spandex covered yarns has further increased. Therefore, more and more research has been conducted on spandex covered yarns. Existing spandex covered yarns have problems with light reflection and refraction when used for fabric weaving. Consumers prefer spandex covered yarns with matte effects. In order to meet the requirements of use, we are committed to developing methods to enhance the matte effect of the covered yarn without reducing elasticity. Utility Model Content

[0022] like Figure 1-2As shown, a matte spandex covered yarn comprises a spandex core yarn 1; a first covering yarn layer 2 is spirally wound on the outer surface of the spandex core yarn 1, and a second covering yarn layer 3 is provided on the outer surface of the first covering yarn layer 2; the first covering yarn layer 2 comprises an even number of symmetrically arranged matte composite yarns; the second covering yarn layer 3 comprises a number of matte spandex, and the matte spandex comprises a core portion 31 and a skin portion 32, and the skin portion 32 is a low-melting-point spandex.

[0023] Specifically, the spandex core yarn 1 is an antibacterial spandex core yarn, and the antibacterial spandex core yarn includes a core part and a skin layer, wherein the core part is a polyurethane slice for melt spinning, and the skin layer includes a fiber-forming polymer and a functional additive. Among them, the fiber-forming polymer is a prepolymer obtained by mixing polyether alcohol and isocyanate, and the functional additives include a silver ion compound, an anti-ultraviolet agent, and a matting agent; the functional additives are mixed with the isocyanate, a chain extender solution is added, and the spinning solution is obtained after aging; finally, the composite spinning technology is adopted, and the wet-dry spinning method is used, and the antibacterial spandex fiber is obtained through a spinneret. Using the antibacterial spandex fiber as the antibacterial spandex core yarn has the advantages of good antibacterial properties and certain matting properties.

[0024] Furthermore, four matte composite yarns are provided. Still further, the matte composite yarn includes full matte polyester staple fiber, low melting point fiber and spandex fiber, and the full matte polyester staple fiber, low melting point fiber and spandex fiber are arranged in parallel. Utilizing the characteristics of low melting point fiber, the full matte polyester staple fiber and spandex fiber arranged in parallel have good structural stability. The matte composite yarn is spirally wound on the outer surface of the spandex core yarn 1, further ensuring the matte property and elastic recovery performance of the composite yarn as a whole. Preferably, the monofilament fineness of the full matte polyester staple fiber is 0.7-1.5D.

[0025] Further, the outer surface of the first coated silk layer 2 is provided with a second coated silk layer 3, and the second coated silk layer 3 includes a number of matte spandex, and the matte spandex is provided with two strands, and the matte spandex is reversely spirally arranged on the outer surface of the first coated silk layer 2. This winding method has the advantage of strong structural stability, and the design of its reverse spiral cross protrusion is used to increase the multi-level reflection of light, reduce the reflection effect of light on the outside world, and thus enhance the overall matte property of the composite silk. Further, the core 31 of the matte spandex is a spandex fiber, the low melting point spandex melting range of the skin 32 is 90-125°C, and the matting agent is evenly distributed in the skin 32. In this embodiment, the matting agent used is nano titanium dioxide.

Furthermore, the skin part 32 and the core part 31 are concentric circles, and the area ratio between the two is 2:5. The matte spandex can ensure the elasticity of use and give the silk thread a matte effect.
