Abstract
Description
Technical Field
[0001] This utility model relates to the field of fabric technology, and in particular to a waterproof and warm brushed denim fabric. Background Technology
[0002] Denim fabric, as a classic and widely used textile material, is loved by consumers for its unique style, durability, and versatility. However, traditional denim fabric is usually woven from cotton warp and weft yarns. While cotton fibers have some warmth retention, they cannot provide enough heat retention for the wearer in cold winters, causing rapid heat loss and resulting in cold and discomfort. Therefore, it is necessary to improve existing technology to solve these problems. Utility Model Content
[0003] The purpose of this invention is to provide a waterproof and warm brushed denim fabric, which aims to solve the problem that traditional denim fabrics made of cotton warp and weft yarns have poor warmth retention.
[0004] To achieve the above objectives, this utility model provides a waterproof and warm fleece denim fabric, which is woven from warp and weft yarns. The minimum weave cycle consists of eight warp yarns and eight weft yarns. The weft yarns include a first weft yarn and a second weft yarn, which are arranged in a 1:1 ratio. The first weft yarn has five warp weft points and three weft weft points, and the second weft yarn has six warp weft points and two weft weft points. The number of warp yarns between the same weft weft points of adjacent first weft yarns is two, and the number of warp yarns between the same weft weft points of adjacent second weft yarns is two. The warp yarns are slub yarn and plain yarn. Both the first and second weft yarns are AB yarns. The AB yarn is a mixture of high-filament A yarn and high-filament B yarn, twisted together. The A yarn is a blend of white polyester filament and spandex, and the B yarn is gray polyester filament yarn. This waterproof and warm fleece denim fabric has a fleece structure layer and a waterproof layer arranged sequentially from the inside out.
[0005] Furthermore, within the minimum weave cycle, the weave points on each first weft yarn are sequentially set to two weft weave points, four warp weave points, one weft weave point, and one warp weave point, and the weave points on each second weft yarn are sequentially set to two warp weave points, one weft weave point, four warp weave points, and one weft weave point.
[0006] Furthermore, the warp yarns include a first warp yarn and a second warp yarn. The first warp yarn is made of slub yarn, and the second warp yarn is made of plain yarn. In the smallest weave cycle, the eight warp yarns from left to right are: first warp yarn, second warp yarn, second warp yarn, second warp yarn, first warp yarn, second warp yarn, second warp yarn, second warp yarn.
[0007] Furthermore, the yarn count of both the first warp and the second warp is 14S-18S.
[0008] Furthermore, the fineness of the white polyester filament in yarn A is 180D-220D, and the fineness of the spandex is 50D-90D.
[0009] Furthermore, the number of monofilaments in yarn A is 155-228.
[0010] Furthermore, the fineness of B yarn is 100D-200D.
[0011] Furthermore, the number of monofilaments in yarn B is 108-180.
[0012] Furthermore, the warp yarns of this waterproof and warm brushed denim fabric have a lower linear density than the weft yarns.
[0013] Furthermore, the waterproof layer is a water-based PU dense film layer.
[0014] This invention provides a waterproof and warm brushed denim fabric. Compared to existing technologies, this denim fabric utilizes the differences in the weft yarn's stitch points and arrangement to make the exposed weft yarns easier to brush during the brushing process, increasing the quantity and density of the pile and further enhancing the fabric's warmth. Moreover, the combination of different warp and weft yarns allows the denim fabric to form a denser pile layer after brushing, greatly increasing the fabric's heat retention capacity and allowing the wearer to feel warmth for a longer period in cold environments. At the same time, the AB yarn gives the denim fabric a cashmere-like color and quality, and the waterproof layer enhances the fabric's waterproof performance. Attached Figure Description

[0017] The present invention will be described in detail below with reference to specific embodiments.
[0018] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.
[0019] This utility model provides a waterproof and warm brushed denim fabric, such as Figure 1 As shown, the waterproof and warm brushed denim fabric has a brushed structure, which is woven from warp and weft yarns. The minimum weave cycle is woven from eight warp yarns and eight weft yarns. The weft yarns include a first weft yarn 21 and a second weft yarn 22. The first weft yarn 21 and the second weft yarn 22 are arranged in a 1:1 ratio. The first weft yarn 21 has five warp weft points 13 and three weft weft points 23. The second weft yarn 22 has six warp weft points 13 and two weft weft points 23. The number of warp yarns between the same weft weft points 23 between adjacent first weft yarns 21 is two, and the number of warp yarns between the same weft weft points 23 between adjacent second weft yarns 22 is two. The warp yarns are slub yarn and plain yarn, and the first weft yarn 21 and the second weft yarn 22 are both AB yarn. The AB yarn is made by mixing and twisting high-F A yarn and high-F B yarn (in the textile industry, high-F yarn usually refers to yarn with F number (number of single filaments) ≥72F). The A yarn is a blend of white polyester filament and spandex, and the B yarn is gray polyester filament yarn. This waterproof and warm brushed denim fabric has a brushed structure layer and a waterproof layer arranged from the inside out.
[0020] Based on the above structural design, the denim fabric, through the differences in the weft yarns' stitching points and arrangement, makes it easier for the exposed weft yarns to produce fluff during the napping process, increasing the quantity and density of the fluff and further enhancing the fabric's warmth. Moreover, the combination of different warp and weft yarns allows the denim fabric to form a denser fluff layer after napping, greatly increasing the fabric's heat retention capacity and allowing the wearer to feel warmth for a longer period in cold environments. At the same time, the AB yarn also gives the denim fabric a cashmere-like color and quality, and the waterproof layer increases the denim fabric's waterproof performance.
[0021] It should be noted that the brushed structure layer is achieved through a brushing process, which is existing technology. Those skilled in the art should be clear about its structure, principle, and usage, so it will not be described in detail here.
[0022] In this embodiment, within the minimum weave cycle, the weave points on each first weft yarn 21 are sequentially set to two weft weave points 23, four warp weave points 13, one weft weave point 23, and one warp weave point 13, and the weave points on each second weft yarn 22 are sequentially set to two warp weave points 13, one weft weave point 23, four warp weave points 13, and one weft weave point 23.
[0023] In this embodiment, the warp yarns include a first warp yarn 11 and a second warp yarn 12. The first warp yarn 11 is made of slub yarn, and the second warp yarn 12 is made of plain yarn. In the minimum weave cycle, the eight warp yarns from left to right are: first warp yarn 11, second warp yarn 12, second warp yarn 12, second warp yarn 12, first warp yarn 11, second warp yarn 12, second warp yarn 12, and second warp yarn 12. The aforementioned ratio of slub yarn to plain yarn makes the denim fabric softer and more comfortable.
[0024] In this embodiment, the yarn count of the first warp 11 and the yarn count of the second warp 12 are both 14S-18S, and more preferably, the yarn count of the first warp 11 and the yarn count of the second warp 12 are both 16S.
[0025] In this embodiment, the fineness of the white polyester filament in yarn A is 180D-220D, and the fineness of the spandex is 50D-90D. More preferably, the fineness of the white polyester filament in yarn A is 200D, and the fineness of the spandex is 70D.
[0026] In this embodiment, the number of monofilaments in yarn A is 156-228, and more preferably, the number of monofilaments in yarn A is 192.
[0027] In this embodiment, the fineness of yarn B is 100D-200D, and more preferably, the fineness of yarn B is 150D.
[0028] In this embodiment, the number of monofilaments in yarn B is 108-180, and more preferably, the number of monofilaments in yarn B is 144.
[0029] Based on the above selections and tests, it has been shown that denim fabrics made with the above yarn count, fineness, and number of monofilaments are more likely to produce fine and dense nap during the napping process, making the denim fabric feel full, soft, and thick.
[0030] In this embodiment, the linear density of the warp yarns in the waterproof and warm brushed denim fabric is less than that of the weft yarns, which allows the weft yarns to emerge on the surface and facilitates the formation of full and uniform pile.
[0031] In this embodiment, the waterproof layer is a water-based PU dense film layer. This water-based PU dense film layer enhances the waterproof performance of the waterproof and warm fleece denim fabric. The formation process of the water-based PU dense film layer is as follows: water-based PU emulsion is evenly coated onto the surface of the denim fabric using a weaving machine, and then baked at a high temperature of 150-160℃ to promote the fusion, cross-linking, and curing of the emulsion particles, ultimately forming a flexible, water-resistant, dense film layer, thereby giving the denim fabric its waterproof function. This process is existing technology and a classic method maturely applied in the industry.
[0032] In summary, this waterproof and warm brushed denim fabric can solve the problem of poor warmth retention in traditional denim fabrics made of cotton warp and weft yarns.
[0033] Where there is no conflict, the above embodiments and features can be combined with each other.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
