Abstract
Description
Technical Field
[0001] This utility model relates to the field of knitted fabric technology, and in particular to a far-infrared heat-insulating knitted fabric. Background Technology
[0002] With advancements in yarn raw materials and spinning technology, numerous new materials and processes have been applied to fabric production, resulting in a wide variety of functional fabrics on the market to meet consumer demands. Among existing technologies, many fabrics possess far-infrared heat-insulating properties. These fabrics primarily work by absorbing heat emitted by the human body and reflecting it back to the skin through far-infrared fibers, thus achieving warmth. However, existing far-infrared heat-insulating fabrics have poor breathability, preventing the timely release of moisture generated by the body. This leads to moisture accumulation between the fabric and the skin, causing discomfort, reducing the user's wearing experience, and potentially causing rashes or other problems. Furthermore, excessive body humidity results in faster heat conduction, reducing the heat-insulating effect and increasing the risk of catching a cold. Utility Model Content

[0037] The far-infrared thermal knitted fabric, made of combed cotton yarn and polyester with a special weaving structure, has good thermal insulation and breathability. It can expel moisture generated by the body in time, preventing moisture from accumulating between the fabric and the skin, thus avoiding a decrease in the user's wearing experience. Moreover, it prevents the user from catching a cold due to excessive heat conduction caused by moisture accumulation, thus avoiding a decrease in the thermal insulation effect.
[0038] The far-infrared thermal knitted fabric combines warmth and moderate breathability, maintaining thermal comfort while also meeting the physiological needs of the human body, thus improving the user's wearing comfort.
[0039] The outer layer is formed by the sixth pattern 6, the seventh pattern 7, the thirteenth pattern 13, and the fourteenth pattern 14; the inner layer is formed by the first pattern 1, the second pattern 2, the third pattern 3, the fourth pattern 4, the eighth pattern 8, the ninth pattern 9, the tenth pattern 10, and the eleventh pattern 11; and the outer and inner layers are connected together by the fifth pattern 5 and the twelfth pattern 12.
[0040] Specifically, the needle arrangement in the knitting structure includes the knitting needle arrangement order and the knitting needle arrangement order. The knitting needle arrangement order is AAAA, and the knitting needle arrangement order is 0B0C, where A represents the knitting needle, B represents the first knitting needle, C represents the second knitting needle, and 0 represents the needle being pulled.
[0041] In a specific embodiment of this utility model, the knitting needles used include upper knitting needles, first knitting needles, and second knitting needles. The upper knitting needles are located above the knitting fabric surface, while the first and second knitting needles are both located below the knitting fabric surface. The arrangement sequence of the upper knitting needles is AAAA, and the arrangement sequence of the first and second knitting needles is 0B0C. Needle removal involves selectively removing or disabling knitting needles to change the fabric structure. By removing needles, the needle position can be dynamically adjusted to achieve special patterns.
[0042] By using the knitting needles, the first knitting needle, and the second knitting needle, combed cotton yarn and polyester can be woven into fabric.
[0043] Specifically, the organizational structure of the first pattern 1 is, in sequence, a floating thread structure, a clustered structure, and a looped structure;
[0044] The organizational structure of the second pattern 2 is, in sequence, a floating weave, a looped weave, and a tucked weave;

Both the pineapple-like and beaded effects are achieved through a three-dimensional coil structure formed by the cyclic weaving pattern. The outer layer exhibits a honeycomb-like structure with raised and recessed areas, resembling a pineapple peel, providing a rough and three-dimensional feel. Each raised unit forms an independent air chamber, effectively trapping still air through the three-dimensional cross-linking structure between fibers, reducing heat convection loss.

[0061] Furthermore, the low-elasticity polyester has a specification of 300D / 576F.
[0062] 300D / 576F indicates that the polyester fiber is 300 denier, and each bundle contains 576 individual fibers. Using low-elasticity polyester of the above specifications gives the fabric strong tensile strength and abrasion resistance, as well as high strength, lightness and durability.
