Technical Field

[0001] This utility model relates to the field of polyester DTY composite yarn, and in particular to a polyester DTY composite yarn. Background Technology

[0002] Polyester DTY composite yarn is an important material in the textile industry, and its performance directly affects the quality and function of the final product. Traditional polyester DTY composite yarn has limitations in its overall performance, especially in terms of flame retardancy, antibacterial properties, and dyeing uniformity, making it difficult to meet the growing market demand.

[0003] Therefore, it is essential to invent a polyester DTY composite yarn. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention provides a technical solution for polyester DTY composite yarn: a polyester DTY composite yarn, comprising a polyester DTY composite yarn body, wherein the polyester DTY composite yarn is provided with a core layer, a covering layer, an outer layer, a functional layer and an optimization layer from the inside to the outside.

[0005] Preferably, the core layer comprises high-modulus polyester fibers and nano-alumina modified fibers, which are twisted together.

[0006] Preferably, the coating layer is made of aerogel-modified polyester fiber.

[0007] Preferably, the outer layer is made of multiple fine flame-retardant DTY polyester filaments tightly wound together.

[0008] Preferably, the functional layer includes micro-silver ion fibers and regenerated fibers, with several micro-silver ion fibers and regenerated fibers respectively, and uniformly embedded in the polyester DTY composite yarn body to form a mixture.

[0009] Preferably, the optimized layer is made of polyester fiber with a microporous structure.

[0010] Compared with the prior art, the advantages of this utility model are:

[0011] High-modulus polyester fibers ensure that the composite yarn maintains high strength and good abrasion resistance during processing and use.

[0012] The nano-alumina modified fibers in the core layer and the aerogel modified polyester fibers in the coating layer work together to significantly improve the flame retardant properties of the composite yarn.

[0013] The micro-silver ion fibers in the functional layer effectively inhibit bacterial growth, providing long-lasting antibacterial protection for textiles.

[0014] The tightly wound outer layer of fine flame-retardant DTY polyester filaments, combined with the special design of the dyeing optimization layer, ensures that the composite yarn has excellent softness and comfortable feel while maintaining strength.

[0015] The outermost layer of microporous polyester fiber allows dye molecules to penetrate deep into the fiber, achieving a bright, uniform, and long-lasting dyeing effect. Attached Figure Description

[0023] Example

[0024] Reference Figure 1-2 A polyester DTY composite yarn includes a polyester DTY composite yarn body, and the polyester DTY composite yarn is provided with a core layer 1, a covering layer 2, an outer layer 3, a functional layer 4 and an optimization layer 5 from the inside to the outside.

[0025] Specifically, the connection method between the core layer 1 and the covering layer 2 is as follows:

[0026] Melt bonding: After the high-modulus polyester fibers of core layer 1 are twisted together with nano-sized alumina-modified fibers, they can be bonded to the aerogel-modified polyester fibers of coating layer 2 through melt bonding technology. In the molten state, the polyester fiber molecular chains undergo mutual diffusion and entanglement, thereby achieving a tight bond.

[0027] Chemical bonding: A thin layer of chemical adhesive is applied between the core layer 1 and the covering layer 2. The adhesive is cured by heating to bond the two layers together firmly.

[0028] Specifically, the connection method between the covering layer 2 and the outer layer 3 is as follows:

[0029] Network Interweaving: The aerogel-modified polyester fibers of the coating layer 2 can be combined with the fine flame-retardant DTY polyester filaments of the outer layer 3 through a network interweaving method. In this way, the polyester filaments of the outer layer 3 will be tightly wrapped around the fibers of the coating layer 2, forming a stable network structure.

[0030] Thermal bonding: Utilizing the thermoplasticity of polyester fibers, heating causes the fibers of the covering layer 2 and the outer layer 3 to melt and bond at the contact point, thereby achieving a tight bond between the two layers.

[0031] Specifically, the embedding method of functional layer 4 is as follows:

[0032] Fiber blending: During the preparation of composite yarns, a mixture of fine silver ion fibers and regenerated cellulose fibers is blended and embedded into the polyester DTY composite yarn body. In this way, the mixed fibers are evenly distributed inside the polyester DTY composite yarn body, forming a functional reinforcing layer.

[0033] Interlayer bonding: A thin layer of adhesive is applied between functional layer 4 and the adjacent layer. The adhesive is cured by heating to achieve the bonding effect, firmly bonding functional layer 4 to the adjacent layer.

[0034] Specifically, optimize the connection between layer 5 and outer layer 3:

[0035] Direct coating: The optimized layer 5, made of polyester fiber with a microporous structure, is directly coated onto the surface of the outer layer 3 as a coating. In this method, the optimized layer 5 adheres tightly to the outer layer 3, forming a uniform microporous structure layer.

[0036] Melt bonding utilizes the thermoplasticity of polyester fibers. By heating, the polyester fibers of the optimized layer 5 and the polyester filaments of the outer layer 3 melt bond at the contact point, thereby achieving a tight bond between the two layers.

[0037] Core layer 1 is made of high-modulus polyester fiber with a diameter of 0.15 mm and nano-alumina modified fiber with a diameter of 0.1 mm twisted together.

[0038] The coating layer 2 uses aerogel-modified polyester fiber with a diameter of 0.08 mm.

[0039] The outer layer 3 is made of flame-retardant DTY polyester filaments with a diameter of 0.12mm, tightly wound at a density of 20 turns per centimeter.

[0040] The functional layer 4 contains a mixture of fine silver ion fibers and bamboo fibers in a 1:3 ratio.

[0041] The optimized layer 5 uses polyester fibers with a microporous structure and a diameter of 0.1 mm.

[0042] In another embodiment, based on the above, the core fiber ratio can be adjusted, the content of nano-alumina modified fiber can be increased to 0.12 mm, and the winding density of the outer flame-retardant DTY polyester filament can be optimized to 25 turns per centimeter, so as to further improve the flame-retardant performance and dyeing uniformity of the composite yarn.

[0043] Any technical solution designed by those skilled in the art using the technical solution described in this utility model, or inspired by the technical solution of this utility model, that achieves the above-mentioned technical effects, falls within the protection scope of this utility model. 。
