[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figures 1-5 This utility model provides an elastic cotton-like three-dimensional fabric, comprising: an upper layer, a middle layer and a lower layer.

[0026] The upper layer is a three-dimensional, upward-convex, cotton-like fabric layer woven from highly elastic polyester filaments, with an elastic recovery rate of >90%.

[0027] The upper layer can be T8 high-elastic polyester filament. T8 high-elastic polyester filament is a fiber made by twisting and spinning PBT fiber (polybutylene terephthalate) and PET fiber (i.e. polyester fiber). T8 high-elastic polyester filament is a high-performance elastic fiber with a unique microstructure like a spiral spring. Its elastic recovery rate is over 90%, and its high-temperature dyeing shrinkage rate is 15% to 18%. It has a cotton-like feel and features moisture-wicking, skin-friendly comfort, and low carbon emissions.

[0028] The upper layer can also be a high-elastic polyester filament formed by twisting and combining PTT fiber (poly(1,3-propylene terephthalate)) and PET fiber (i.e., polyester fiber). PTT fiber combines the characteristics of polyester, nylon, and acrylic. In addition to good stain resistance, it is easy to dye, soft to the touch, and elastic. Its elongation is as good as spandex fiber, and it is easier to process than the elastic fiber spandex. PTT fiber has a cotton-like feel, mainly reflected in its soft hand feel and excellent drape. The combination of PTT fiber and PET fiber is soft and has excellent drape, with a touch similar to cotton fabric, making it comfortable to wear.

[0029] The middle layer, woven from polyester filaments, connects the upper and lower layers. Its primary function is as a link, reducing costs and preventing pilling. The lower layer is woven from spandex.

[0030] In this embodiment, the upper layer is woven from circular cross-section fully matte T8 high-elastic polyester filaments. The high matte finish and fully matte characteristics give the fabric a soft sheen without glaring reflection, creating a low-key, high-end feel. The specification used is T8 high-elastic polyester filament DTY111Dtex / 96F. The middle layer is woven from circular cross-section semi-matte polyester filaments. The semi-matte characteristic gives the middle layer a unique sheen, which is not overly dazzling but contrasts and harmonizes with the upper and lower layers, increasing the overall texture and depth of the fabric. The specification used is DTY83Dtex / 72F. The lower layer is woven from high-temperature resistant spandex, using a specification of 44 Dtex. The lower layer is a brushed layer. After brushing, a fine nap forms on the fabric surface, giving it a soft, warm feel and enhancing comfort when worn against the skin, thus improving the user experience. Simultaneously, the brushed layer increases the fabric's warmth, providing good insulation even in cold seasons.

[0031] like Figures 1-5 As shown, the fabric in this embodiment adopts a 16-way circulating yarn arrangement. The first, second, third, fourth, fifth, and sixth yarns are all woven with a middle layer of polyester filament and a lower layer of spandex; the seventh, eighth, ninth, tenth, eleventh, eleventh, twelfth, thirteenth, thirteenth, thirteenth, thirteenth, thirteenth, thirteenth, thirteenth, and sixteenth yarns are all woven with an upper layer of high-elastic polyester filament.

[0032] The fabric is knitted on a high-density fine needle single-sided weft circular knitting machine with a gauge of 28 needles / 25.4mm. The normal operating speed is controlled at 15R / MIN, and the yarn tension is controlled at 2-3cN to avoid uneven tension that may cause fuzzy needles, horizontal stripes, skipped needles, yarn flipping, and yarn dropping. The needle plate uses BABA needles, and the needle cylinder uses ABCD needles with double-sided needles.

[0033] The yarn length for each of the 1st, 2nd, 3rd, 4th, 5th, and 6th passes should be controlled at 27.5cm / 100 stitches. The length of the high-elastic polyester filament yarn for each of the 7th, 8th, 9th, 10th, 11th, 12th, 13th, 14th, 15th, and 16th passes should be controlled at 16.5cm / 100 stitches. The spandex yarn length should be controlled at 10cm / 100 stitches. The weight of the finished fabric should be controlled within the range of 180±10g / m².

[0034] For rows 1, 3, and 5, the first stitch of each needle bed is not knitted, and the second stitch is knitted into a loop. The first and second stitches of the needle tube are also knitted into a loop. For rows 2, 4, and 6, the first stitch of each needle bed is knitted into a loop, and the second stitch is not knitted. The first and second stitches of the needle tube are also knitted into a loop. For rows 7, 9, 11, 13, and 15, the needle bed is not knitted, the first and third stitches of the needle tube are not knitted, and the second and fourth stitches of the needle tube are knitted into a loop. For rows 8, 10, 12, 14, and 16, the needle bed is not knitted, the first and third stitches of the needle tube are knitted into a loop, and the second and fourth stitches of the needle tube are not knitted.

[0035] The finished fabric has a transverse loop density of 46-48 W / cm and a longitudinal loop density of 68-72 C / cm. The finished fabric has a width of 148-153 cm and a weight of 320-330 gsm.

[0036] The performance parameters of the fabric (top layer is T8 high-elastic polyester filament) in this embodiment were tested, and the test report is shown in Table 1 below:

[0038]

[0039] As shown in Table 1, in addition to having a cotton-like effect and good elasticity, the fabric of this utility model also has hydrophilicity, breathability and warmth retention properties, making it suitable for outdoor sports.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
