Description

Technical Field

[0001] This utility model relates to the field of composite fabric technology, and more specifically, to a highly breathable composite fabric. Background Technology

[0002] Composite fabrics utilize advanced technology and new materials from "new synthetic fibers," possessing many superior properties (compared to ordinary synthetic fibers), such as a fine, delicate, elegant, and warm fabric appearance, a full and windproof, breathable fabric appearance, and a certain degree of waterproofing.

[0003] Composite fabrics are manufactured by bonding specific films onto the finished fabric using composite equipment. Existing composite fabrics have a wide range of applications, especially in the outdoor jacket manufacturing industry, where they can meet the requirements of waterproofing and lightweight. However, as clothing, they also need to have a breathable effect to ensure wearing comfort. Therefore, it is necessary to design a structure to enhance the breathability of composite fabrics.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a highly breathable composite fabric.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a highly breathable composite fabric, comprising a base fabric, wherein the base fabric is woven by warp and weft yarns in a three-up-three-down weft plain weave, with each group of three warp yarns forming a group, and the spacing between adjacent warp yarn groups and the spacing between adjacent weft yarns being greater than the diameter of the weft yarns, wherein a breathable membrane is fixed to one side of the base fabric by adhesive, and the adhesive is applied in the shape of several staggered arcs.

[0007] The present invention is further configured such that: every three warp yarns form a group, the yarn count of the middle yarn of the warp yarn group is less than the yarn count of the side yarns of the warp yarn group, the weft yarn is the same as the middle yarn of the warp yarn group, and the weft yarn and the warp yarn group are coated with foam adhesive at the intersection.

[0008] The present invention is further configured such that: the intermediate yarn in the weft and warp yarn group is a moisture-permeable yarn, the moisture-permeable yarn includes a yarn core and an outer wrapping yarn spirally wound on its outside, the yarn core is made by twisting several 100D / 72F polyester DTY yarns, and the outer wrapping yarn is a cotton-linen blended yarn.

[0009] The present invention is further configured such that the side yarn of the warp yarn group is 100D / 72F polyester DTY.

[0010] The present invention is further configured such that a moisture-permeable groove is formed between the adjacent weft yarns and the adjacent warp yarns.

[0011] The present invention is further configured such that: a plurality of protrusions are formed at the interlacing point of the middle yarn and the weft yarn of the warp yarn group, and the array of protrusions is distributed on both sides of the base fabric.

[0012] The present invention is further configured such that the moisture-permeable membrane can be a PTFE waterproof and moisture-permeable membrane.

[0013] The present invention is further configured such that the moisture-permeable membrane can be configured as a TPU type waterproof and moisture-permeable membrane.

[0014] In summary, this utility model has the following beneficial effects:

[0015] The raised design reduces the contact area between the base fabric and the body surface when the base fabric is used to make clothing. This raised support creates a gap between the base fabric and the body surface, allowing air to circulate. The flowing air accelerates the evaporation of moisture from the body surface and the fabric, making the fabric more comfortable and breathable. The side yarns of the warp yarn group have a smaller diameter, and after weaving, the middle yarn of the warp yarn group also supports the side yarns, creating space between the side yarns and the weft yarns. The reduction in the number of connections between the warp and weft yarns also improves the overall moisture permeability and breathability of the fabric. The overall moisture permeability of the composite fabric formed by combining PTFE waterproof and breathable membrane, TPU waterproof and breathable membrane, and base fabric can reach 3056*24=73344.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Example 1:

[0024] A highly breathable composite fabric, such as Figure 1As shown, it includes a base fabric 1, which is woven from warp yarns 2 and weft yarns 3 in a three-up-three-down weft plain weave. Every three warp yarns 2 form a group. When the reed is fixed on the water jet loom, three warp yarns form a group. Some gaps are reserved between adjacent warp yarn groups. The weft yarns 3 are weft-knitted into the warp yarns 2 to obtain the base fabric 1. The base fabric obtained by the weft plain weave has obvious stripes. Moreover, compared with the plain weave, the weft plain weave has better air permeability and moisture permeability.

[0025] like Figures 1-4 As shown, the spacing between adjacent warp yarn groups and the spacing between adjacent weft yarns 3 are both greater than the diameter of the weft yarn 3. Every three warp yarns 2 form a group. The yarn count of the middle yarn of the warp yarn group is smaller than that of the side yarns of the warp yarn group. The weft yarn 3 is the same as the middle yarn of the warp yarn group. Foam is applied to the interlacing point of the weft yarn 3 and the warp yarn group. Due to the relatively loose overall weaving density, deformation is likely to occur during the composite process. The foam is used to pre-fix the interlacing point of the warp yarn 2 and the weft yarn 3, making the composite process more stable and smooth. At the same time, the foam makes the protrusion 9 more prominent, forming several protrusions at the interlacing point of the middle yarn of the warp yarn group and the weft yarn 3. 9. The raised array 9 is distributed on both sides of the base fabric. The setting of the raised array 9 reduces the contact area between the base fabric 1 and the body surface when the base fabric 1 is made into clothing. Thus, the raised array 9 supports the gap between the base fabric 1 and the body surface, allowing air to circulate in this gap. The flowing air accelerates the moisture dissipation speed between the body surface and the fabric, making the fabric more comfortable and breathable to use. The side yarns of the warp yarn group have a smaller diameter. After weaving, the middle yarn of the warp yarn group will also support the side yarns, so that a space is also formed between the side yarns and the weft yarns 3. The reduction of the connection between the warp yarns 2 and the weft yarns 3 will also improve the overall moisture permeability and breathability of the fabric.

[0026] like Figures 1-2 As shown, a moisture-permeable groove 8 is formed between adjacent weft yarns 3 and adjacent warp yarn groups. This not only creates a space for air circulation between the weft yarns 3 and warp yarn groups, but also allows air circulation between adjacent warp yarn groups and weft yarns 3, making the base fabric 1 appear as a mesh. A moisture-permeable membrane 4 is fixed to one side of the base fabric with adhesive 10. The moisture-permeable membrane 4 can be a PTFE waterproof and breathable membrane 4. The micropore size of the PTFE waterproof and breathable membrane 4 is 1 / 5000-1 / 20000 of the diameter of a water droplet, so even the smallest raindrop cannot pass through. The PTFE waterproof and breathable membrane 4 has low surface energy, preventing water droplets from passing through. Spread on a thin film to prevent water droplets from passing through, the PTFE waterproof and breathable membrane 4 forms a microporous structure during the stretching process, with nodes connected to countless microfibers. Pores are formed between the microfibers, and these pores are interconnected, forming a unique network structure. Wind cannot pass through directly and will change direction and turn back when it encounters an obstacle, effectively preventing air penetration. Therefore, it has excellent windproof performance. The porosity of the PTFE waterproof and breathable membrane 4 is as high as 80%, with an average pore size of 0.2um. The micropore size is more than 700 times larger than that of water vapor molecules, allowing water vapor molecules to pass through freely, ensuring the overall waterproof and breathable effect of the composite fabric.

[0027] like Figures 1-2 As shown, the adhesive 10 is applied in a pattern of several staggered arcs. The arc shape of the adhesive 10 allows the same adhesive 10 to cover a larger area, making the PTFE waterproof and breathable membrane 4 less prone to tearing and falling off during subsequent use. Furthermore, the base fabric 1 itself can maintain its shape through the stretching of the adhesive 10, making the composite fabric less prone to deformation and extending its service life. After testing, the overall breathability of the composite fabric after applying the PTFE waterproof and breathable membrane 4 can reach 3056*24=73344.

[0028] like Figures 3-5 As shown, the weft yarn 3 and the intermediate yarn in the warp yarn group are set as breathable yarn 5. The breathable yarn 5 includes a yarn core 6 and an outer wrapping yarn 7 spirally wound on its outside. The yarn core 6 is made by twisting several 100D / 72F polyester DTY. The outer wrapping yarn 7 is made of cotton and linen blended yarn. The side yarns of the warp yarn group are made of 100D / 72F polyester DTY. Several 100D / 72F polyester DTY are twisted by a twisting machine to obtain the yarn core 6 and the side yarns of the warp yarn group. The cotton and linen blended yarn is spirally wound on the outside of the yarn core 6 through a spinning process to obtain the breathable yarn 5. Polyester fiber has high strength and good toughness. The base fabric 1 formed by processing polyester fiber as the main raw material has a longer service life. The cotton and linen blended yarn has good moisture permeability. Moreover, the cotton and linen blended yarn is sparsely wound when spirally wound. The distance between adjacent pitches of the cotton and linen blended yarn forming the outer wrapping yarn 7 is large, which also facilitates air circulation and enhances the moisture permeability of the composite fabric.

[0029] Example 2:

[0030] The difference from Example 1 is that, as Figures 1-2 As shown, the breathable membrane 4 is a TPU type waterproof and breathable membrane 4. The TPU type waterproof and breathable membrane 4 has the same breathability principle as the PTFE waterproof and breathable membrane 4. After testing, it can also achieve a breathability of 3056*24=73344. However, the TPU type waterproof and breathable membrane 4 has better abrasion resistance and can better adapt to some scenarios with high abrasion resistance requirements, such as the production of some shoes.

[0031] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
