[0002] Fabric is the material used to make clothing. As one of the three essential elements of clothing, fabric not only interprets the style and characteristics of clothing, but also directly influences the color and shape of the garment. Fabric generally possesses characteristics such as comfortable wear, breathability, good drape, elegant appearance, and soft touch. Brushing is a textile process where the fabric surface is brushed with a brushing machine and abrasive padding to create a short, fuzzy layer. This process retains the original characteristics while giving the fabric a new style, increasing warmth and softness, and ensuring colorfastness.

[0003] A prior art patent document, CN201921764095.9, discloses a lightweight composite thermal fabric characterized by comprising a fabric body; the fabric body includes an outer fabric and an inner fabric; the outer fabric is a single-sided terry cloth; the single-sided terry cloth is composed of plain knit loops and terry loops with elongated sinker arcs; the outer fabric is woven from cashmere yarn; the surface of the outer fabric is brushed to form a fleece layer; the inner fabric is a jersey fabric; the jersey fabric is woven from thermal yarn; the outer and inner fabrics are connected and composited by spandex yarn. The above technical solution features lightweight, soft touch, and good thermal insulation performance. It primarily achieves its thermal insulation effect through brushing to form a fleece layer and by increasing the internal air content, resulting in a soft, fluffy, and comfortable garment.

[0004] However, the multi-layer structure connection of the above-mentioned technical solutions relies on traditional stitching or simple gluing, and does not form an integrated interwoven structure.

[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0025] refer to Figure 1 As shown, the brushed thermal fabric according to an embodiment of the present invention includes an inner layer 100, a middle thermal insulation layer 200, and an outer layer 300 arranged sequentially from the inside to the outside along the thickness direction. These three layers are fixed together by 18 interconnecting yarns arranged in a circular pattern. The inner layer 100 is woven from yarns 1, 4, 7, 10, 13, and 16; the middle thermal insulation layer 200 is woven from yarns 2, 5, 8, 11, 14, and 17; and the outer layer 300 is woven from yarns 1, 4, 7, 10, 13, and 16. The 3rd, 6th, 9th, 12th, 15th, and 18th yarns are interwoven; among the 18 yarns, the 1st, 2nd, 4th, 5th, 7th, 8th, 10th, 11th, 13th, and 14th yarns are warp yarns, and the 3rd, 6th, 9th, 12th, 15th, 16th, 17th, and 18th yarns are weft yarns; the warp and weft yarns interweave to form nodes at the junctions of each layer, the inner layer 100 has a short pile layer 400 on the side facing the human body, and the warp and weft yarns of the outer layer 300 form diamond-shaped pores.

[0026] In practical use, the inner layer 100, the middle insulation layer 200, and the outer layer 300 are tightly integrated through multiple yarns, effectively preventing separation between layers. The diamond-shaped pores of the outer layer 300 ensure breathability while avoiding excessive pore size that would reduce warmth. The short pile layer 400 and the middle insulation layer 200 work together to form a double insulation structure, balancing warmth and breathability.

[0027] In some specific embodiments of this utility model, it may also have the following additional technical features: the weaving structure of the 1st, 4th, 7th, 10th, and 13th yarns of the inner layer 100 is all of the following: loop up, float down, loop up, loop down; and the weaving structure of the 16th yarn is also of the following: float up, loop up, loop down, loop down. The weaving structure of "loop up + float down + float up + loop down" makes the inner layer 100 form a uniform loop gap, providing a stable fiber base for the napping process and avoiding localized loss of nap during napping; the special weaving structure of the 16th yarn enhances the connection strength between the inner layer 100 and the intermediate insulation layer 200, ensuring that the interlayer nodes are not easily loosened, while avoiding napping difficulties caused by excessively dense loops at the edges of the inner layer 100.

[0028] In some specific embodiments of this utility model, it may also have the following additional technical features: the weaving structure of the 2nd, 5th, 8th, 11th, and 14th yarns of the intermediate insulating layer 200 is all of the following: looping, tucking, floating, and floating stitches; the weaving structure of the 17th yarn is of the following: floating stitches, looping, looping, and floating stitches. The looping structure of the looping makes the intermediate insulating layer 200 form a fluffy fiber accumulation, which can retain more still air; the alternating arrangement of the looping and forming units prevents the intermediate insulating layer 200 from becoming too fluffy and resulting in a loose structure; the plain weave structure of the 17th yarn enhances the fit between the intermediate insulating layer 200 and the outer layer 300, ensuring uniform force transmission between layers and preventing local deformation when the fabric is stretched.

[0029] In some specific embodiments of this utility model, it may also have the following additional technical features: the weaving structure of the 3rd, 6th, 9th, 12th, and 15th yarns of the outer layer 300 is a combination of floating stitch, looped stitch, looped stitch, and gathered stitch; the weaving structure of the 18th yarn is a combination of looped stitch, floating stitch, floating stitch, and looped stitch. The combination of "floating stitch + looped stitch + looped stitch + gathered stitch" allows the outer layer 300 to naturally form diamond-shaped gaps, with uniform gap size and resistance to deformation, while also preventing stuffiness when worn. The gathered stitch structure enhances the interlacing tightness of the outer layer 300 yarns, improves the outer layer 300's anti-snagging ability, and at the same time, the weaving structure of the 18th yarn optimizes the connection between the edge of the outer layer 300 and the middle insulating layer 200, laying the foundation for the subsequent edge loop formation.

[0030] In some specific embodiments of this utility model, it may also have the following additional technical features: the short pile layer 400 is formed by a brushing process. The brushing process is a commonly used technical solution in the prior art, and will not be described in detail here.

[0031] In some specific embodiments of this utility model, it may also have the following additional technical features: the 1st, 4th, 7th, 10th, 13th, and 16th yarns of the inner layer 100 are all blended yarns, which are interwoven with polyester staple fibers and thermal staple fibers. The polyester staple fibers and thermal staple fibers are arranged alternately along the length of the yarn, and the diameter of the thermal staple fibers is smaller than that of the polyester staple fibers. The polyester staple fibers provide sufficient strength to prevent fiber breakage during brushing, while the thermal staple fibers (such as cashmere staple fibers and wool staple fibers) enhance the skin-friendliness and warmth of the inner layer 100. The alternating arrangement of the two makes the inner layer 100 both strong and soft; the thermal staple fibers have a slightly smaller diameter, making it easier to form uniform nap during brushing, avoiding uneven nap thickness caused by uniform fiber diameter, and improving the consistency of the brushed layer's feel.

[0032] In some specific embodiments of this utility model, it may also have the following additional technical features: at the tucking units of the 2nd, 5th, 8th, 11th, and 14th yarns of the intermediate insulation layer 200, the yarns form a double-layer winding structure. The double-layer winding yarns are hooked to the loops of adjacent looping units, and gaps are reserved between the double-layer yarns of the tucking units. The double-layer winding structure enhances the fluffiness of the tucking units, and the tiny gaps can retain more still air, further improving the warmth retention performance of the intermediate insulation layer 200. The hooking design with adjacent looping units prevents the tucking units from loosening, ensuring that the intermediate insulation layer 200 quickly returns to its original shape after stretching, improving structural stability by 30%, and maintaining fluffiness even after long-term use.

[0033] In some specific embodiments of this utility model, it may also have the following additional technical features: In the 3rd, 6th, 9th, 12th, 15th, and 18th yarns of the outer layer 300, the surface of the warp yarns has three grooves extending along the length of the yarns. The extension direction of the grooves is consistent with the direction of the warp yarns, and one end of each groove is connected to the diamond-shaped pores of the outer layer 300. The grooves on the surface of the warp yarns create a capillary effect, accelerating the transfer of moisture from the inside of the fabric to the outside, preventing sweat retention during wear; the grooves are connected to the diamond-shaped pores, forming a complete breathable and moisture-wicking channel, ensuring rapid moisture removal without affecting the warmth and structural strength of the outer layer 300.

[0034] In some specific embodiments of this utility model, it may also have the following additional technical features: at the nodes where each layer intersects, the warp yarn passes under the weft yarn and wraps around the weft yarn once before interlacing with the next weft yarn. The winding length of the warp yarn and the weft yarn at the node is consistent. The node structure of "winding + interlacing" makes the warp and weft yarns more firmly bonded, preventing separation between layers due to loose nodes; the consistent winding length ensures that each node is subjected to uniform force, and there is no local stress concentration when the fabric is stretched, making it less prone to coil deformation, further improving the stability of the interlayer structure.

[0035] In some specific embodiments of this utility model, it may also have the following additional technical features: at the four edges of the fabric, the 18th yarn of the outer layer 300 and the 17th yarn of the middle insulating layer 200 interweave to form continuous edge loops. The edge loops are arranged alternately, and the yarn tension of the edge loops is consistent with the yarn tension of the main body of the fabric. The continuous edge loops prevent the fabric edges from unraveling, extending the product's service life; the alternating arrangement ensures smooth edges without protrusions or depressions, not affecting wearing comfort; the consistent yarn tension between the edge loops and the main body prevents edge shrinkage or wrinkling after washing, ensuring fabric dimensional stability.

[0036] refer to Figure 2 The inner layer 100 weaving focuses on the following: the “∨-----∧” structure of the 1st, 4th, 7th, 10th, and 13th (warp direction) to ensure uniform spacing between the inner layer 100 coils, providing a stable base for the brushing process; and the “--∨-∧--” structure of the 16th (weft direction) to strengthen the interlayer connection between the inner layer 100 and the middle insulation layer 200.

[0037] refer to Figure 2 The key points of knitting the middle insulation layer 200 are: the “∨---∩--” structure of the 2nd, 5th, 8th, 11th and 14th rows (warp direction), which forms a double-layered wrapped fluffy unit by gathering the knitted stitches (∩) to retain still air; the “--∧-∨--” structure of the 17th row (weft direction) balances the fit between the middle insulation layer 200 and the outer layer 300.

[0038] refer to Figure 2 The outer 300 weave focuses on the following: the “--∨-∧-∩” structure of the 3rd, 6th, 9th, 12th, and 15th weft directions naturally forms diamond-shaped gaps; the “∨-----∧” structure of the 18th weft direction, together with the 17th weft direction of the middle insulation layer 200, forms the basis of the edge coil.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
