Description

Technical Field

[0001] This utility model relates to knitted fabrics, and more specifically, to a lightweight, temperature-regulating, and breathable knitted fabric. Background Technology

[0002] Knitted fabrics are generally used in everyday wear such as underwear, T-shirts, and sportswear, offering good comfort. However, knitted fabrics used for outdoor activities like running are mostly plain knitted with minimal texture variation to reduce snagging. This results in poor moisture absorption and wicking properties, leaving the body in an uncomfortable environment during prolonged exercise.

[0003] Compared to traditional round cross-section yarns, high-count nylon yarns with irregular cross-sections have a larger specific surface area and capillary channels, which helps to accelerate the removal of sweat and moisture.

[0004] Nylon phase change temperature regulating yarn contains phase change materials, which can undergo a solid-liquid phase change at temperatures close to human skin temperature, maintaining a constant temperature by absorbing or releasing heat.

[0005] Based on this, this application attempts to weave a temperature-regulating and breathable fabric using these two functional yarns on a single machine, while avoiding the problem of coupling of different yarn weaving trajectories. Utility Model Content

[0006] To address the aforementioned technical problems, the technical solution of this utility model is as follows: A lightweight, temperature-regulating, and breathable knitted fabric, characterized in that it comprises a fabric woven on a double-sided circular knitting machine with an asymmetrical needle plate and needle cylinder using nylon high-count irregular cross-section yarn and nylon phase change temperature-regulating yarn. The fabric pattern is woven from a two-needle upper needle plate and a four-needle lower needle cylinder, and the fabric pattern forms a cycle every 32 rows. In the upper needle plate section, lines 1, 2, 7, 12, 17, 18, 23, and 28 are all circular stitches; lines 3-6, 8-11, 13-16, 19-22, 24-27, and 29-32 are all floating stitches. In the lower syringe section, lines 1 and 17 are both floating thread tissue; lines 2, 7, 12, 18, 23, and 28 are alternating between tufted and floating thread tissue; lines 3-5, 8-10, 13-15, 19-21, 24-26, and 29-31 are alternating between coiled and floating thread tissue; and lines 6, 11, 16, 22, 27, and 32 are all coiled tissue.

[0007] As a preferred embodiment of this utility model, the upper needle plate triangle is divided into two segments AB, and the lower needle cylinder triangle is divided into three segments ABC.

[0008] As a preferred embodiment of this utility model, the triangular arrangement is as follows: needle plate: AB, syringe: BABC.

[0009] As a preferred embodiment of this utility model, the alternating structure of loops and floats is as follows: The triangular configuration of section A of the lower syringe is as follows: channels 2, 7, and 12 are all floating thread tissue, and channels 18, 23, and 28 are all tufted tissue. The triangular configuration of section B of the lower syringe is such that channels 2, 7, 12, 18, 23, and 28 are all floating thread tissues; The triangular configuration of the lower syringe C section is as follows: channels 2, 7, and 12 are all tufted tissue, and channels 18, 23, and 28 are all floating tissue.

[0010] As a preferred embodiment of this utility model, the alternating weave of loops and floats is as follows: The triangular configuration of section A of the lower syringe is as follows: the 3rd, 5th, 8th, 10th, 13th, 16th, 19th, 21st, 24th, 26th, 29th, and 31st are all looped tissues, and the 4th, 9th, 14th, 20th, 25th, and 30th are all floating tissues. The triangular configuration of section B of the lower syringe is as follows: lines 3, 5, 8, 10, 13, 16, 19, 21, 24, 26, 29, and 31 are all floating thread tissue, while lines 4, 9, 14, 20, 25, and 30 are all looped tissue. The triangular configuration of the lower syringe C section is as follows: the 3rd, 5th, 8th, 10th, 13th, 16th, 19th, 21st, 24th, 26th, 29th, and 31st channels are all circular tissues, while the 4th, 9th, 14th, 20th, 25th, and 30th channels are all floating tissues.

[0011] As a preferred embodiment of this utility model, the parameters of the high-count nylon irregular cross-section yarn are 30D-50D.

[0012] As a preferred embodiment of this utility model, the parameters of the nylon phase change temperature regulating yarn are 40D-70D.

[0013] As a preferred embodiment of this utility model, channels 1, 2, 7, 12, 17, 18, 23, and 28 use 40D-70D nylon phase change temperature regulating yarn; channels 3-6, 8-11, 13-16, 19-22, 24-27, and 29-32 use 30D-50D nylon high-count irregular cross-section yarn.

[0014] It should be noted that the above technical solution uses fine denier yarn, which results in a lighter overall weight and achieves lightweight fabric.

[0015] The advantages of this utility model are: 1. This application requires weaving two functional yarns in a single machine, which can easily lead to the problem of coupling of multi-material weaving trajectories. To address this, the fabric design of this application adopts an asymmetrical double-sided circular knitting machine structure, with the needle plate and needle cylinder executing different weaving routes. Some routes on the upper needle plate use loops (e.g., routes 1, 2, 7, 12, 17, 18, 23, and 28), while the rest are floats. The lower needle cylinder uses an alternation of loops and floats, as well as loops and floats, to refine the allocation of local loop requirements, thus enabling the equipment to have better adaptability.

[0016] In particular, the needle cylinder uses ABC triangular zones to control different needle paths, achieving precise control over the weaving position and movement trajectory of two different yarns, thereby reducing problems such as weaving misalignment, tension imbalance, and yarn breakage caused by coupling of multiple materials in the weaving trajectory.

[0017] 2. This application requires the use of nylon high-count irregular cross-section yarn. Due to the flatness and roughness of the yarn, it is easy to cause loop pressing and loop jamming problems in the loop forming process. If a mesh structure is forcibly woven, structural shrinkage, mesh closure and reduced air permeability are also likely to occur after loop forming.

[0018] To address this, this application distributes the loop-forming pressure of the fabric in a staggered manner in the longitudinal and transverse directions, employing a three-way interweaving arrangement of loop-forming, float, and tucking structures; grouping the yarns and combining them with an asymmetrical needle plate and cylinder design, thereby ensuring that the mesh structure is not compressed, achieving stable mesh formation, good resilience, and excellent breathability, thus avoiding the loop-forming problem of traditional high specific surface area yarns.

[0019] 3. In addition, the fabric of this application is woven by an asymmetrical double-sided machine, which can achieve different appearances and properties on the front and back of the fabric. The upper needle plate is responsible for weaving the "front structure" with two needle tracks, and the structure is relatively tight. The lower needle cylinder is responsible for weaving the "skin-contact structure" with four needle tracks, and the structure is more sparse and loose.

[0020] Therefore, the front side features a tight and delicate plain weave structure, which helps block the intrusion of external ultraviolet rays; the side that touches the skin has a smooth and loose mesh structure, which facilitates the rapid wicking away of moisture. The outer layer of the fabric is made of high-count nylon irregular cross-section yarn, which has a large specific surface area and can increase the speed of moisture removal; the inner layer is made of nylon phase change temperature regulating yarn, which is used to regulate the microclimate changes around the skin, keeping the body in a comfortable environment.
