Description

Technical Field

[0001] This utility model relates to the field of textile fabric technology, specifically to a temperature-regulating double-layer woven fabric. Background Technology

[0002] With economic development and technological advancements, consumers are demanding higher levels of comfort from textiles. Functional chemical fiber fabrics, which can impart a wide variety of properties to yarns during the production process, are gradually gaining popularity. However, in summer or high-temperature environments, clothing made from existing chemical fiber fabrics often suffers from poor breathability and heat buildup, leading to stuffiness and discomfort for consumers. This drawback limits the market application of chemical fiber fabrics.

[0003] To improve the temperature control comfort of textiles, existing technologies have introduced solutions that apply temperature-regulating fibers to textiles. For example, CN216968950U discloses a smart temperature-regulating fiber shoe upper mesh fabric, including a shoe upper mesh fabric body composed of a comfort layer, an antibacterial layer, a temperature-regulating layer, an elastic layer, a reinforcing layer, and a wear-resistant layer. The temperature-regulating layer is positioned between the antibacterial layer and the elastic layer and is woven from temperature-regulating fibers. This mesh fabric only achieves a simple application of temperature-regulating fibers, which are present as separate layers within the fabric, making it difficult to meet the requirements of lightweight summer clothing fabrics. Therefore, how to structurally combine temperature-regulating fibers with yarns to achieve continuous and stable dynamic temperature regulation while ensuring the fabric's lightweight and breathable properties remains a pressing technical challenge in this field. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a temperature-regulating double-layer woven fabric that addresses the shortcomings of the existing technology. This fabric is lightweight yet crisp, with a soft and smooth surface and a vertical stripe pattern. It can continuously and stably adjust the contact temperature between the fabric and the body according to changes in the external temperature, making it suitable as a fabric for summer casual clothing and providing consumers with a better wearing experience.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a temperature-regulating double-layer woven fabric, comprising a fabric body woven from warp and weft yarns, the fabric body having a double-layer structure composed of an outer weave and a lining weave, both the outer and lining weaves being plain weaves, the warp yarns being composed of outer warp and lining warp, the weft yarns being composed of outer weft and lining weft, the outer warp, outer weft, and lining warp being all nylon-covered spandex yarn, the lining weft being composed of nylon-covered spandex yarn, cupro fiber, and phase change temperature-regulating fiber arranged in sequence, the arrangement of the warp and weft yarns being as follows: the outer warp and lining warp are arranged in a 1:1 ratio, the outer weft and lining weft are arranged in a 1:1 ratio, the number of cycles in a complete warp weave is 4, and the number of cycles in a complete weft weave is 8.

[0006] This utility model of woven fabric adopts a double-layer structure. Its outer warp, outer weft, and inner warp are all made of nylon-covered spandex yarn, while the inner weft is composed of nylon-covered spandex yarn, cupro fiber, and phase change temperature-regulating fiber arranged in sequence. Combined with a specific yarn arrangement, the fabric is given the following advantages: the fabric surface is smooth and wear-resistant, has good wrinkle resistance, does not easily fade after washing, and maintains its new appearance for a long time; the nylon-covered spandex yarn and phase change temperature-regulating fiber on the reverse side of the fabric bring a continuous cooling sensation to the skin, while the cupro fiber can further improve the fabric's hand feel and enhance its moisture absorption performance; the fabric maintains its lightweight characteristics while possessing good crispness.

[0007] Preferably, the outer warp, outer weft, and inner warp are all 50D-70D, and the nylon-covered spandex yarn, cupro fiber, and phase change temperature-regulating fiber that make up the inner and weft yarns are 50D-70D, 50D-70D, and 40D-60D, respectively. The finer yarn specifications ensure the fabric's lightweight yet crisp characteristics.

[0008] As a further preferred embodiment, the outer warp, outer weft, and inner warp are all made of 30D nylon-covered 20D spandex-covered yarn, and the inner weft consists of nylon-covered spandex yarn, cupro fiber, and phase change temperature-regulating fiber with specifications of 30D nylon-covered 20D spandex-covered yarn, 50D cupro fiber, and 40D phase change temperature-regulating fiber, respectively.

[0009] Compared with existing technologies, this novel temperature-regulating double-layer woven fabric has the following advantages: the fabric surface is smooth and wear-resistant, wrinkle-resistant, and does not easily fade after washing, maintaining its new appearance for a long time; the nylon-covered spandex yarn and phase change temperature-regulating fibers on the reverse side of the fabric provide a continuous cooling sensation to the skin, while the cupro fiber further improves the fabric's feel and enhances its moisture absorption performance; the fabric maintains its lightweight characteristics while possessing good crispness. This novel temperature-regulating double-layer woven fabric provides a continuous cooling sensation to the skin, and compared with conventional double-layer woven fabrics of the same structure without phase change temperature-regulating fibers, the maximum temperature difference can reach 4.6℃. This novel temperature-regulating double-layer woven fabric is lightweight yet crisp, with a soft and smooth surface feel and a vertical striped style. It can continuously and stably adjust the contact temperature between the fabric and the body according to changes in external temperature, making it suitable as a fabric for summer casual clothing, providing consumers with a better wearing experience.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The yarn materials and structures not specified in the present invention all employ conventional techniques in the art.

[0015] The temperature-regulating double-layer woven fabric of the embodiment includes a fabric body woven from warp and weft yarns. The fabric body has a double-layer structure consisting of an outer weave and a back weave. Both the outer weave and the back weave are plain weaves. The warp yarns consist of outer warp and back warp, and the weft yarns consist of outer weft and back weft. The outer warp, outer weft, and back warp are all nylon-covered spandex yarns. The back weft is composed of nylon-covered spandex yarns, cupro fiber, and phase change temperature-regulating fiber arranged in sequence.

[0016] In this embodiment, the outer warp, outer weft, and inner warp are all made of 30D nylon-covered 20D spandex-covered yarn. The specifications of the nylon-covered spandex yarn, cupro fiber, and phase change temperature-regulating fiber that make up the inner weft are 30D nylon-covered 20D spandex-covered yarn, 50D cupro fiber, and 40D phase change temperature-regulating fiber, respectively. The phase change temperature-regulating fiber accounts for 10% of the mass of this temperature-regulating double-layer woven fabric.

[0017] In this embodiment, the warp and weft yarns are arranged as follows: the front warp and back warp are arranged in a 1:1 ratio, the front weft and back weft are arranged in a 1:1 ratio, the number of cycles in a complete warp structure is 4, and the number of cycles in a complete weft structure is 8. For example... Figure 1 As shown, inner warp I and outer weft 4 interweave, forming one cycle. Outer warp 1 and 2 interweave with outer weft 1, 2, 3, and 4 in a plain weave structure. Inner warp I interweaves with inner weft 1 and 3, and inner warp II interweaves with inner weft 2 and 4, forming one cycle. Inner weft I uses nylon-covered spandex yarn, inner weft II uses cupro fiber, and inner weft III uses phase change temperature-regulating fiber, forming one cycle. Because inner warp I yarn contains spandex, it has high elasticity. After interweaving, the yarn rebounds, pulling the outer weft yarn downwards, thus creating a raised, vertical stripe pattern on the fabric surface.

[0018] According to the test method for the maximum temperature difference during heating / cooling specified in Appendix A of T / GDBX 064-2023 "Phase Change Temperature-Regulating Fibers and Textiles", the maximum temperature difference during heating / cooling of the above-mentioned temperature-regulating double-layer woven fabric and a conventional double-layer woven fabric with the same structure but without phase change temperature-regulating fibers were tested. The melting enthalpy and crystallization enthalpy of the above-mentioned temperature-regulating double-layer woven fabric were also tested according to GB / T 19466.3-2004 "Differential Scanning Calorimetry (DSC) for Plastics - Part 3: Determination of Melting and Crystallization Temperatures and Enthalpies". The test results are shown in the table below:

[0019]

[0020] As can be seen, the melting enthalpy of the aforementioned temperature-regulating double-layer woven fabric reaches 9.0 J / g, and the crystallization enthalpy reaches 8.7 J / g, which can provide a continuous cooling sensation to the skin. Compared with conventional double-layer woven fabrics with the same structure but without phase-change temperature-regulating fibers, the temperature difference between the two can reach up to 4.6℃.
