[0023] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] As Figures 1 to 5 shown, the present utility model provides a thermal insulation fabric formed by weft knitting of multiple yarns. The multiple yarns at least include a first yarn, a second yarn and a third yarn arranged in sequence. The first yarn is a first polyester filament. The second yarn at least includes carbon energy fiber. The third yarn at least includes a first combed cotton compact spun yarn.

[0025] In this embodiment, the carbon energy fiber is a carbon energy polyester fiber or a plant carbon fiber, which is made by implanting nano-plant carbon into a masterbatch and then processing and spinning it into a yarn. The nano-plant carbon is a material extracted from plants. Materials such as nano-plant carbon are implanted into the fiber. This material has a special graphitized microcrystalline structure and an irregular cross-linked layered structure. It has many pores, small pore diameters and a larger specific surface area. After absorbing the heat of the human body, it will stimulate and release far-infrared rays of 45um to 12um. It is infinitely close to the far-infrared wavelength of the human body (4 to 20um). It is more easily absorbed and beneficial to physical health. And when far-infrared rays irradiate the human body or other objects, it will resonate with the molecules inside the object, thereby promoting the molecules to move more violently, and then generating heat. This way can make people feel warmer and more comfortable, because the heat is generated from the inside, rather than simply relying on the heating of the external air.

[0026] This fabric also has an antibacterial function. Bacteria with negative charges will be attracted by the metal ions (with positive charges) released by the nano-powder in the carbon energy fiber, restricting the freedom of movement of the bacteria and inhibiting their respiratory functions, that is, "contact death" occurs. Under the action of the electric field gravity, the uneven distribution of negative charges on the cell wall and cell membrane of the bacteria causes deformation, and the cell wall undergoes physical rupture, and the microbial metabolism terminates, and it cannot grow and reproduce.

[0027] In the above-mentioned embodiment, the fabric forms a jacquard tissue with a stepped texture. The fabric has stepped texture fabric patterns, far-infrared, thermal insulation and antibacterial functions.

[0028] The multiple yarns also include a fourth yarn, a fifth yarn and a sixth yarn. The fourth yarn is a first polyester filament. The fifth yarn at least includes carbon energy fiber. The sixth yarn at least includes a second combed cotton compact spun yarn. The second yarn and the fifth yarn include carbon energy fiber and a second polyester filament. The third yarn includes a first combed cotton compact spun yarn and an elastic yarn, and the first combed cotton compact spun yarn covers the surface of the elastic yarn.

[0029] In this embodiment, both the first polyester filament and the second polyester filament are round-section semi-dull polyester filaments. The elastic yarn is spandex with a specification of 39-49 DTEX. The yarn arrangement of the fabric is a cycle of six paths. The first path and the fourth path both knit the first polyester filament; the third path knits the first combed cotton compact spun yarn to cover the spandex; the sixth path knits the second combed cotton compact spun yarn, and the second path and the fifth path both knit carbon energy fiber and the second polyester filament.

[0030] The first polyester filament uses a specification of 78-88 Dtex and 19-29 F, the second polyester filament uses a specification of 106-116 Dtex and 139-149 F; the first combed cotton spun yarn uses a count of 16-24, and the second combed cotton spun yarn uses a count of 35-45; the carbon energy fiber uses a specification of 106-116 Dtex and 139-149 F.

[0031] In this embodiment, the first polyester filament uses a round-section semi-dull polyester filament DTY83 Dtex / 24 F, the second polyester filament uses a round-section semi-dull polyester filament DTY111 Dtex / 144 F, the first combed cotton spun yarn uses 20s / 1 combed cotton compact spun yarn, the second combed cotton spun yarn uses 40s / 1 combed cotton compact spun yarn, and the elastic yarn uses high-temperature resistant spandex 44 DTEX.

[0032] In the above embodiment, the combed cotton compact spun yarn and spandex can significantly improve the quality, performance and comfort of the fabric. The combed cotton compact spun yarn can make the fabric smoother and flatter, enhancing moisture absorption and durability; while spandex can significantly enhance the elasticity of the fabric, improve dimensional stability and enhance the warmth retention performance. These improvements make the fabric more suitable as a fabric for winter clothing.

[0033] The control of the length of the greige fabric is as follows:

[0034] The yarn lengths of the first path yarn and the fourth path yarn are controlled at 27.8-28.3 cm / 100 needles, the yarn lengths of the third path yarn and the sixth path yarn are controlled at 30.8-31.3 cm / 100 needles, and the yarn lengths of the second path yarn and the fifth path yarn are controlled at 23.8-24.3 cm / 100 needles. The spandex yarn length is controlled at 11.8-12.3 cm / 100 needles.

[0035] The loop structure form of the fabric, in the arrangement order from the needle dial to the needle cylinder, is as follows: the first path is float, stitch formation, tuck; the second path is stitch formation, float, float, float; the third path is float, float, stitch formation, stitch formation; the fourth path is stitch formation, float, float, tuck; the fifth path is float, stitch formation, float, float; the sixth path is float, float, stitch formation, stitch formation.

[0036] As Figures 2 to 5As shown, the specific knitting process is as follows: In the first and fourth courses, the first needles on the dial knit loops, and the second needles do not participate in knitting. The first needles on the cylinder knit tuck stitches, and the second needles do not participate in knitting. In the third and sixth courses, the cylinders participate in knitting loops, and the dials do not participate in knitting. In the second and fifth courses, only the second needles on the dial participate in knitting, and the others do not participate in knitting.

[0037] In this embodiment, a high-density fine-needle single-sided weft knitting large circular knitting machine is used. The normal starting speed is controlled at 15R / MIN, and the yarn feeding tension is controlled at 2 - 3cN to avoid problems such as wool needles, horizontal stripes, skipped stitches, yarn turning, and yarn dropping caused by uneven tension. The dial uses BA needle arrangement, the cylinder uses AB needle arrangement, and the rib is needle-aligned.

[0038] The lateral coil density of the fabric is 34 - 36W / cm; the longitudinal coil density of the fabric is 41 - 43C / cm.

[0039] The finished width of the fabric is 180 - 185cm, and the gram weight is 320 - 340gsm.

[0040] The test data of the fabric is as follows:
