Description

Technical Field

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

[0002] Composite fabric is a new type of material made by bonding one or more layers of textile materials, non-woven materials and other functional materials. It is suitable for making textiles such as sofas and clothing, and is one of the indispensable fabrics for people's home life.

[0003] In order to achieve a better warming effect, the existing thermal insulation fabrics are generally made of airtight materials, so the heat dissipation effect is poor. When exercising in winter, the large amount of heat generated by the body is not easy to dissipate, which will cause stuffiness and affect comfort. Therefore, a new type of composite fabric is needed to solve this problem. Utility Model Content

[0004] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by implementing the utility model. The purpose and other advantages of the utility model can be realized and obtained through the structures specifically pointed out in the description and other drawings of the description.

[0005] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a composite knitted fabric.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is: a composite knitted fabric, comprising an upper layer and a lower layer, wherein the lower layer is provided with a plurality of expansion strips and hydrophobic strips on a side close to the upper layer, the expansion strips and the hydrophobic strips are both connected to the lower layer, a plurality of hydrophobic strips are provided between every two adjacent expansion strips, and there is a gap between the adjacent hydrophobic strips located between the same two expansion strips, the lower layer is provided with a breathable zone 1 at each of the gaps, the upper layer is fixedly connected to each expansion strip, and the upper layer is provided with a breathable zone 2 at a position aligned with each hydrophobic strip.

[0007] By adopting the above technical solution, under normal conditions, the second breathable zone located on the upper layer is attached to the hydrophobic strip. At this time, the air cannot pass through the upper layer through the second breathable zone. Therefore, the hot air inside the fabric is not easy to lose, and the fabric is in a relatively warm state. When the temperature inside the fabric is too high, the human body begins to sweat due to the stuffiness. The expansion strip will expand after absorbing sweat, while the hydrophobic strip is not easy to absorb water and remain the same. At this time, a height difference will be generated between the expansion strip and the hydrophobic strip. Since the upper layer is only connected to the expansion strip, it will be separated from the hydrophobic strip under the support of the expansion strip, and a gap will be formed under the second breathable zone. At this time, the outside world can be connected to the inside of the fabric through the second breathable zone, the gap and the first breathable zone in turn, thereby enhancing heat dissipation and reducing the stuffiness. Therefore, the fabric can have a good warming effect and a good heat dissipation effect under specific conditions. At the same time, the support of the expansion strip and the hydrophobic strip allows a certain amount of air to be stored between the upper and lower layers, thereby enhancing the warming performance of the fabric.

[0008] Preferably, the upper layer and the lower layer are both woven by the warm yarn in a plain weft knitting method. The utility model provides a basis for the formation of the expansion strip and the hydrophobic strip by the plain weft knitting method.

[0009] Preferably, the expansion strip is woven by expansion yarn, and the expansion yarn is interwoven with the lower layer by warp winding weaving with the lower layer as the ground weave. The utility model utilizes the warp winding weaving method to allow the expansion yarn to be woven into the lower layer and connected with the lower layer, while allowing the expansion yarn to float above the lower layer to form an independent convex strip, so that a height difference can be formed with the hydrophobic strip when expanding.

[0010] Preferably, the hydrophobic strips are woven by hydrophobic yarns, and the hydrophobic yarns are interwoven with the lower layer by using a warp-wrap weaving method with the lower layer as the ground weave. The utility model utilizes a warp-wrap weaving method to allow the hydrophobic yarns to be woven into the lower layer and connected to the lower layer, while allowing the hydrophobic yarns to float above the lower layer to form independent convex strips, thereby being unaffected by the expansion of the expansion yarns and forming a height difference with the expansion yarns.

[0011] Preferably, the first breathable area is formed on the lower layer by weaving the transfer loop tissue. The utility model uses the weaving method of the transfer loop tissue to form a plurality of yarn holes on the lower layer formed by the weft plain needle tissue, so that air can pass through the lower layer more easily to form the first breathable area.

[0012] Preferably, the second air permeable zone is formed on the upper layer by weaving a transfer loop tissue. The utility model uses the weaving method of the transfer loop tissue to form a plurality of yarn holes on the upper layer formed by the weft plain needle tissue, so that air can pass through the upper layer more easily to form the second air permeable zone.

[0013] Preferably, the expansion yarn is a knotty fancy yarn made of cotton fiber. The utility model utilizes the strong water absorption of cotton fiber to realize the function of the expansion strip. At the same time, by making the cotton fiber into a knotty fancy yarn, the expansion strip can have a better expansion ability.

[0014] Preferably, the hydrophobic yarn is made of polypropylene fiber. The utility model utilizes the hydrophobic property of polypropylene fiber to achieve the function of the hydrophobic strip.

[0015] Preferably, the thermal insulation yarn is made of cotton fiber. The utility model utilizes the good thermal insulation performance of cotton fiber to achieve the function of the thermal insulation yarn.

[0016] In summary, the beneficial effects of the utility model are:

[0017] 1. By utilizing the different water absorption characteristics of the expansion strip and the hydrophobic strip, the two can produce a height difference after absorbing sweat, thereby separating the breathable area 2 from the hydrophobic strip and enhancing the heat dissipation performance of the fabric. When no sweat is produced, the breathable area 2 is attached to the hydrophobic strip 2 and is in a non-conductive state, so that the fabric remains relatively warm, allowing the fabric to adapt to different situations.

[0018] 2. The support of expansion strips and hydrophobic strips allows a certain amount of air to be stored between the upper and lower layers, thereby enhancing the warmth retention performance of the fabric.

[0019] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure.

[0031] like Figure 1 As shown, a composite knitted fabric comprises an upper layer 1 and a lower layer 2, wherein the lower layer 2 is provided with a plurality of expansion strips 3 and hydrophobic strips 4 on a side close to the upper layer 1, the expansion strips 3 and the hydrophobic strips 4 are connected to the lower layer 2, a plurality of hydrophobic strips 4 are provided between every two adjacent expansion strips 3, and there is a gap between adjacent hydrophobic strips 4 between the same two expansion strips 3, the lower layer 2 is provided with a breathable area 1 5 at each gap, the upper layer 1 is fixedly connected to each expansion strip 3, and the upper layer 1 is provided with a breathable area 2 6 at a position aligned with each hydrophobic strip 4.

[0032] By adopting the above technical solution, under normal conditions, the air permeable area 2 6 located on the upper layer 1 is attached to the hydrophobic strip 4. At this time, air cannot pass through the upper layer 1 through the air permeable area 2 6, so the hot air inside the fabric is not easy to escape, and the fabric is in a relatively warm state. When the temperature inside the fabric is too high, the human body begins to sweat due to the stuffiness, and the expansion strip 3 will expand after absorbing sweat, while the hydrophobic strip 4 is not easy to absorb water and remains the same. At this time, a height difference will be generated between the expansion strip 3 and the hydrophobic strip 4. Since the upper layer 1 is only in contact with the expansion strip 3, the hydrophobic strip 4 will not be easily absorbed. The expansion strips 3 are connected, so they will be separated from the hydrophobic strips 4 under the support of the expansion strips 3, and a gap will be formed under the breathable area 2 6. At this time, the outside world can be connected with the inner side of the fabric through the breathable area 2 6, the gap and the breathable area 1 5 in sequence, thereby enhancing heat dissipation and reducing the feeling of stuffiness, so that the fabric can have a good heat dissipation effect under specific conditions while having a good warming effect. At the same time, the support of the expansion strips 3 and the hydrophobic strips 4 allows a certain amount of air to be stored between the upper layer 1 and the lower layer 2, thereby enhancing the thermal insulation performance of the fabric.

[0033] The upper layer 1 and the lower layer 2 are both woven by the warm yarn in the weaving mode of the weft plain needle organization, which provides a basis for the formation of the expansion strip 3 and the hydrophobic strip 4.

[0034] The expansion strip 3 is woven by expansion yarn, and the expansion yarn is interwoven with the lower layer 2 by warp winding weaving with the lower layer 2 as the ground weave. The warp winding weaving method allows the expansion yarn to be woven into the lower layer 2 and connected with the lower layer 2, while the expansion yarn floats above the lower layer 2 to form an independent convex strip, so that a height difference can be formed with the hydrophobic strip 4 when expanding.

[0035] The hydrophobic strips 4 are woven by hydrophobic yarns, and the hydrophobic yarns are interwoven with the lower layer 2 by using the warp winding weaving method with the lower layer 2 as the ground weave. The warp winding weaving method allows the hydrophobic yarns to be woven into the lower layer 2 and connected with the lower layer 2, while the hydrophobic yarns float above the lower layer 2 to form independent convex strips, so that they are not affected by the expansion of the expansion yarns and form a height difference with the expansion yarns.

[0036] The breathable area 5 is formed on the lower layer 2 by the knitting method of the transfer loop tissue. A plurality of yarn holes are formed on the lower layer 2 formed by the weft plain needle tissue by the knitting method of the transfer loop tissue, so that air can pass through the lower layer 2 more easily, forming the breathable area 5.

[0037] The second breathable area 6 is formed on the upper layer 1 by weaving the transfer loop tissue. A plurality of yarn holes are formed on the upper layer 1 formed by the weft plain needle tissue by weaving the transfer loop tissue, so that air can pass through the upper layer 1 more easily, forming the second breathable area 6.

[0038] The expansion yarn is a knotty fancy yarn made of cotton fiber. The strong water absorption of cotton fiber is used to realize the function of the expansion strip 3. At the same time, by making cotton fiber into a knotty fancy yarn, the expansion strip 3 can have a better expansion ability.

[0039] The hydrophobic yarn is made of polypropylene fiber. The hydrophobic property of the polypropylene fiber is utilized to realize the function of the hydrophobic strip 4.

[0040] The thermal yarn is made of cotton fiber, and the function of the thermal yarn is realized by utilizing the good thermal insulation performance of cotton fiber.

[0041] It should be noted that many specific details are set forth in the above description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.
