Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a warm and breathable weft knitted fabric. Background Art

[0002] At present, the fabrics with warmth-keeping function for winter wear are generally filled with down or cotton. The existing process mainly involves weaving the surface layer and the bottom layer fabrics separately, then filling them with warmth-keeping materials, and then fixing and sealing them with threads. Since filling and sealing are required, the fabric cannot be directly obtained by direct cutting, and the process is complex, which limits large-scale industrial production. At the same time, fabrics with good warmth retention often have poor air permeability and are not easy to dissipate heat.

[0003] A weft knitted double-layer jacquard fabric with both air permeability and warmth retention and its production method with the authorization announcement number of CN 111549432 B discloses that the weft knitted double-layer jacquard fabric includes a warmth-keeping area and an air-permeable area. The warmth-keeping area is a hollow structure, and warmth-keeping yarns are filled in the hollow structure; the weft knitted double-layer jacquard fabric is woven by a double-layer jacquard machine, computer jacquard, and the needle cylinder needles are arranged in a 12-row needle arrangement; the triangular configuration of the warmth-keeping area is as follows: ──∨─∨───. Users can freely design the pattern of the jacquard pattern according to needs and select the positions of the warmth-keeping area and the air-permeable area on the fabric, so that the fabric can achieve the warmth-keeping and / or air-permeable effect locally or integrally. Although the fabric is integrally woven by a weft knitted double-layer large circular knitting machine and the production process is simple and can be mass-produced, through the combined setting of the positions of several warmth-keeping areas and air-permeable areas, the warmth-keeping materials are locked in the warmth-keeping area, but the air-permeable area does not have a hollow structure and is not filled with warmth-keeping materials and does not have a warmth-keeping function. In addition, when the area of the warmth-keeping area is large enough, the warmth-keeping materials are likely to be unevenly distributed in the warmth-keeping area. Summary of the Utility Model

[0004] Therefore, it is necessary to provide a warm and breathable weft knitted fabric to solve the problem of uneven distribution of fillers in the existing fabrics with fillers, and provide a warm and breathable weft knitted fabric with uniform distribution.

[0005] To achieve the above object, the utility model provides a warm and breathable weft knitted fabric. The warm and breathable weft knitted fabric is a double-layer fabric, which includes a surface layer and a bottom layer. There is a hollow structure between the surface layer and the bottom layer, and fillers are filled in the hollow structure to form a filling layer. There are connecting lines interwoven between the surface layer and the bottom layer to limit the positions of the fillers.

[0006] Further, the fillers are evenly distributed in the hollow structure.

[0007] Further, the connecting lines are evenly interwoven between the surface layer and the bottom layer.

[0008] Furthermore, the warm and breathable weft knitted fabric has a breathable area, and the breathable area has breathable holes.

[0009] Furthermore, at least part of the connecting lines are fine yarns, and the breathable holes are formed by the fine yarns at the interweaving part of the surface layer and the bottom layer to form a pore penetrating the surface layer, the filling layer and the bottom layer.

[0010] Furthermore, the warm and breathable weft knitted fabric has a warm area, and the bottom layer of the warm area is a fleece surface.

[0011] Furthermore, the fleece surface is polar fleece.

[0012] Furthermore, the warm and breathable weft knitted fabric is integrally knitted and formed by a weft knitting double-layer large circular knitting machine.

[0013] Furthermore, the connecting lines are interwoven in the surface layer and the bottom layer during the knitting process.

[0014] Furthermore, the filling material is filled between the surface layer and the bottom layer through a yarn clamping nozzle during the knitting process to form a filling layer.

[0015] Different from the prior art, the above technical solution uses connections to interweave in the surface layer and the bottom layer to limit the filling material in the hollow structure between the surface layer and the bottom layer, effectively limiting the position of the filling material, preventing it from shifting or accumulating during use, keeping the filling material in its original position, and making the filling material have stability.

[0041] See Figures 1-5As shown in the figure, the present utility model provides a warm and breathable weft knitted fabric, which solves the problem of uneven distribution of the filling 302 in the existing fabric with filling 302; by connecting and interweaving the surface layer 10 and the bottom layer 20, the filling 302 in the hollow structure 301 between the surface layer 10 and the bottom layer 20 is limited, effectively defining the position of the filling 302, preventing it from shifting or accumulating during use, keeping the filling 302 in its original position, and making the filling 302 stable. The above-mentioned warm and breathable weft knitted fabric can be represented by any product and / or article considered feasible and / or appropriate, such as winter clothing (such as sandwich clothes like down jackets, cotton-padded clothes, ski clothes, mountaineering clothes, etc.), home textiles (such as blankets, sheets, pillowcases, etc.), medical uses (such as warm bandages, joint protection sleeves, hot compress patches, rehabilitation aids, etc.).

[0042] See Figures 1-2 As shown in the figure, a warm and breathable weft knitted fabric provided by the present utility model will be described in detail below. A warm and breathable weft knitted fabric, the warm and breathable weft knitted fabric is a double-layer fabric, which includes a surface layer 10 and a bottom layer 20, and there is a hollow structure 301 between the surface layer 10 and the bottom layer 20, and the hollow structure 301 is filled with a filling 302 to form a filling layer 30, and there is a connecting line 40 interwoven between the surface layer 10 and the bottom layer 20 to limit the position of the filling 302.

[0043] The above-mentioned filling 302 has a warming function to enable the warm and breathable weft knitted fabric to have a warming function. In practice, it can be down, fluff, cotton, artificial fiber, wool, etc. The above-mentioned surface layer 10 and bottom layer 20 can be fabrics woven separately, or can be a double-layer fabric formed in the same weaving. A hollow structure 301 is formed between the surface layer 10 and the bottom layer 20 to fill the filling 302 to form a filling layer 30, so as to enable the warm and breathable weft knitted fabric to have a warming function. The surface layer 10 and the bottom layer 20 can be woven with specific material yarns to form a fabric with functions such as windproof, waterproof, and warming. The above-mentioned connecting line 40 is used to limit the position of the filling 302. By interweaving the surface layer 10 and the bottom layer 20, it prevents the filling 302 from shifting or accumulating during use, and keeps the filling 302 in its original position; See Figure 1 As shown in the figure, in some embodiments, when interweaving the surface layer 10 and the bottom layer 20, the filling 302 in the hollow structure 301 first remains evenly distributed, and then the connecting line 40 is used for interweaving; See Figure 2As shown, in some embodiments, during the interweaving process, the same amount of filler 302 is added to each part within the hollow structure 301. By maintaining the uniform distribution of the filler 302 through the connecting lines 40, the warmth retention of the warm and breathable weft knitted fabric is increased, and cold air and moisture are prevented from penetrating through positions without the filler 302. Preferably, the connecting lines 40 are evenly interwoven in the surface layer 10 and the bottom layer 20. The even interweaving of the connecting lines 40 can confine the filler 302 evenly distributed within the hollow structure 301 to its original position through the connecting lines 40, avoiding the aggregation or accumulation of the filler 302; at the same time, it can provide more balanced support for the filler 302, making the filler 302 stable. The above-mentioned connecting lines 40 can be linear, oblique, Z-shaped, cross-shaped, etc. between the surface layer 10 and the bottom layer 20.

[0044] See Figure 3 As shown, the above-mentioned warm and breathable weft knitted fabric has a breathable area, and the breathable area has breathable holes 50. Specifically, pores are created at corresponding positions of the surface layer 10, the filling layer 30, and the bottom layer 20 to promote air circulation. This can increase the breathability of the warm and breathable weft knitted fabric, keep the warm and breathable weft knitted fabric fresh and dry, and at the same time reduce the possibility of bacteria and mold growth in the warm and breathable weft knitted fabric. In some embodiments, mesh holes are formed at certain corresponding parts of the surface layer 10 and the bottom layer 20, and the hollow structure 301 at the mesh holes is not filled with the filler 302 to form the breathable holes 50; in some embodiments, the fine yarn 401 is used as the connecting line 40 of the breathable area, and the breathable hole 50 is a pore that penetrates through the surface layer 10, the filling layer 30, and the bottom layer 20 formed at the interweaving part of the fine yarn 401 between the surface layer 10 and the bottom layer 20. That is, by using the fine yarn 401 to perform the interweaving action, the space between the surface layer 10 and the bottom layer 20 at the interweaving part is larger than that of the thick yarn 402 (the thick yarn 402 only limits the filler 302 during interweaving, and the space left on the surface layer 10 is small and cannot form pores), so as to form a transparent pore, achieving the breathable effect, preventing the filler 302 from flying out through the pore, and at the same time restricting the filler 302. It should be noted that the fine yarn and the thick yarn here only refer to the thickness of the yarn. The fine yarn is relative to the thick yarn, and the thickness of the yarn can be expressed in denier. For example, the thick yarn is 50 - 75D, and the fine yarn is 20 - 40D.

[0045] See Figure 4As shown, the warm and breathable weft knitted fabric has a warm zone. The bottom layer 20 or the top layer 10 of the warm zone is different from other areas and has a heat-insulating surface with heat-insulating function. The bottom layer 20 or the top layer 10 mentioned above is not a structural position, but specifically refers to the skin-friendly surface. In daily applications, usually the bottom layer 20 is the skin-friendly surface, that is, the bottom layer 20 of the warm zone has a heat-insulating surface. The heat-insulating surface can be a surface formed by knitting yarns with this function, and it can be a fluffy surface 201 formed by knitting wool yarns. The fluffy surface 201 has good heat-insulating performance, can effectively block cold air, and reduce heat loss. When the human body touches the fluffy surface 201 of the warm zone, a warmer touch can be felt, providing an additional heat-insulating effect and making people feel more comfortable and warm in cold weather. And the fluffy surface 201 has the characteristics of being soft and skin-friendly, and can provide a more comfortable touch. The fluffy surface 201 in the lower layer of the above-mentioned warm zone can be straight plush, polar fleece, etc.

[0046] It should be noted that the warm zone and the breathable zone only refer to structural differences, not differences in their positions on the warm and breathable weft knitted fabric. There is a possibility that the warm zone and the breathable zone belong to different positions on the warm and breathable weft knitted fabric; there is a possibility that the warm zone and the breathable zone partially overlap or even completely overlap on the warm and breathable weft knitted fabric, there is a possibility that the warm zone covers the breathable zone on the warm and breathable weft knitted fabric; there is a possibility that the breathable zone covers the warm zone on the warm and breathable weft knitted fabric.

[0047] The warm and breathable weft knitted fabric is integrally knitted and formed by a weft knitting double-layer circular knitting machine. When the weft knitting double-layer circular knitting machine knits the top layer 10 and the bottom layer 20, the connecting line 40 on the shuttle connects the top layer 10 and the bottom layer 20, so that the connecting line 40 is interwoven between the top layer 10 and the bottom layer 20 during the knitting process. At the same time, the filler 302 is filled between the top layer 10 and the bottom layer 20 through the yarn clamping nozzle during the knitting process to form a filling layer 30.

[0072] This knitting structure mainly consists of a cycle of 14 courses.

[0073] For the 1st, 4th, 7th, and 10th courses, yarns with a thickness of 100D - 200D and an F count of 144F - 288F can be selected. The yarns can be polyester, cationic, nylon, etc. The main function of this group of yarns is to be used for brushing polar fleece to form a fleece warm-keeping area.

[0074] For the 2nd, 5th, 8th, and 11th courses, thick yarns with a thickness of 50D - 75D and an F count of 24F - 72F can be selected. The yarns can be polyester, cationic, nylon, etc. The main functions are, first, to form an interlacing tissue to lock the filling yarn, and second, to stabilize the yarns in the 1st, 4th, 7th, and 10th courses so that they are not prone to running off during brushing and avoid leakage of the filling yarn.

[0075] For the 13th and 14th courses, fine yarns with a thickness of 20D - 40D and an F count of 12F - 36F can be selected. The yarns can be polyester, cationic, nylon, etc. The main purpose is to use the fine yarns to perform interlacing actions so that the space at the interlacing part of the fabric surface is larger than that of the thick yarns, thereby forming a permeable pore to achieve the effect of ventilation.

[0076] It should be noted that although the above embodiments have been described in this text, the patent protection scope of the present utility model is not limited thereby. Therefore, based on the innovative concept of the present utility model, any changes and modifications made to the embodiments described in this text, or equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, and directly or indirectly applying the above technical solutions to other related technical fields are all included within the protection scope of the patent of the present utility model.
