Description

Technical Field

[0001] The utility model relates to the technical field of polyester stretch yarn, in particular to a composite polyester stretch yarn. Background Art

[0002] Polyester has high strength and elastic recovery ability. Therefore, polyester is durable, wrinkle-resistant, and easy to iron. Most textile fabrics on the market are made by ordinary silk yarn, which has poor elasticity, poor antibacterial effect, and is uncomfortable to wear. Therefore, composite polyester stretch yarn is needed. Composite polyester stretch yarn is a chemical fiber filament made of synthetic fiber thermoplastic with permanent nonlinear curl, fluffy and elastic. It has low elastic expansion and contraction rate, good elasticity, and the fabric can maintain dimensional stability and good breathability, so it is deeply loved by people.

[0003] A composite stretch yarn with publication number CN 109306559A includes a hollow polyester yarn and multiple monofilaments. A metal wire is arranged at the center of the hollow polyester yarn, and a circular protrusion is provided on the inner wall of the hollow polyester yarn. Multiple monofilaments surround the hollow polyester yarn, and the surface of each monofilament is provided with an inwardly concave groove, which is provided on the contact surface with the hollow polyester yarn. The beneficial effects of the present invention are: simple structure, hollow polyester yarn structure and grooves on the surface of the monofilament make the elastic yarn have good air permeability, and at the same time the monofilaments are distributed around the hollow polyester yarn, with good fit, which improves comfort, and the circular protrusions increase the elasticity of the elastic yarn. The metal wire can improve the gloss and reliability of the elastic yarn, meeting the needs; the above-mentioned existing technology still has certain shortcomings when used. When used, it has poor elastic effect. The elasticity of the elastic yarn is enhanced by adding circular protrusions around the hollow polyester yarn, which is a relatively single method, resulting in poor elastic yarn enhancement effect, which in turn causes the elastic yarn to be easily deformed and broken when used. Utility Model Content

[0004] The technical problem to be solved by the present invention is: in order to overcome the above problems, a composite polyester stretch yarn is provided, which solves the above problems.

[0005] The utility model solves the technical problem by adopting the following technical solutions:

[0006] A composite polyester stretch yarn comprises a hollow polyester stretch filament and a twisted outer covering yarn wrapped around the hollow polyester stretch filament. The number of the twisted outer covering yarns is even, and the twisted outer covering yarns are wrapped around the hollow polyester stretch filament using a twisting machine.

[0007] Preferably, the twist coefficient of the twisted outer covering wire is 3.5-4.5.

[0008] Preferably, the twisted outer covering wire is made of carbon fiber wire, spandex fiber wire and acrylic heat-melt wire twisted into wire using a twisting machine.

[0009] Preferably, the twist coefficient of the carbon fiber yarn, spandex fiber yarn, and acrylic heat-melt yarn is 4.5-5.5.

[0010] Preferably, silver ion antibacterial particles are provided in the twisting gaps of the carbon fiber filaments, spandex fiber filaments and acrylic heat-melt filaments.

[0011] Preferably, epoxy resin is applied at the twisting gaps between the twisted outer covering wires.

[0012] The advantages and positive effects of the utility model are: compared with the existing technology, this product adopts a double twisting process, and is loose on the outside and tight on the inside, so that the elastic yarn has higher resistance to bending and folding while having good non-plastic elasticity. Its twisted state enables it to maintain external flatness and better anti-wrinkle performance after weaving. BRIEF DESCRIPTION OF THE DRAWINGS
