Description

Technical Field

[0001] This utility model relates to a tear-resistant, fleece-lined, and warm denim fabric, belonging to the textile field. Background Technology

[0002] Traditional denim fabric is woven from warp and weft yarns. The warp yarns are pure cotton yarn dyed with indigo, while the weft yarns are off-white pure cotton yarns. The tight fit and unique style of traditional denim fabric have made denim clothing a consistently popular choice. With economic development, people's pursuit of clothing has expanded beyond just design; they now place greater emphasis on comfort and functionality. For example, in cold winters, people need warm and comfortable clothing. Fleece is a common method to enhance the warmth of clothing. After weaving, the reverse side of the fabric is fleece-fed, creating a layer of nap on the underside, which enhances its warmth. Fleece essentially hooks the fibers from the yarn. The strength of fabric treated with this process decreases, and currently, fleece-treated denim fabrics suffer significant strength loss and are prone to tearing. Therefore, existing technology needs improvement. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a ripstop-resistant fleece-lined warm denim fabric. Through a special weaving structure, the denim fabric has a good warmth retention effect and is not easy to tear after fleece treatment.

[0004] The technical solution adopted by this utility model to solve its technical problem is: A tear-resistant, fleece-lined, warm denim fabric includes a base layer. The base layer includes two separate systems: a face warp and a back warp, as well as two separate systems: a face weft and a back weft. The face warp and the face weft are twill-woven to form the face layer. The back warp and the face weft are plain-woven to form the middle layer. The back warp and the back weft are woven to form the bottom layer. The face warp and the back weft do not interweave. The bottom layer includes alternating grooves and corduroy stripes along the weft direction. The back warp that forms the grooves forms weft stitches along the entire length of the bottom layer. The back warp that forms the corduroy stripes forms warp stitches along the entire length of the bottom layer. A fleece-lined layer is provided at the bottom of the base layer.

[0005] The tear-resistant fleece-insulating denim fabric provided in this application relies on the solid plain weave structure of the middle layer to maintain the surface and bottom layers, inhibiting yarn slippage after fleece application. The grooves of the bottom layer can utilize still air for insulation, and the raised wick strips are easily hooked up, so that the inner weft is mainly sacrificed during fleece application, reducing damage to the inner warp. This helps to inhibit the decrease in strength of the middle layer after fleece application. The surface and bottom layers are relatively independent, and the fleece damage is mainly in the bottom layer, protecting the structural integrity of the surface layer.

[0006] Furthermore, the number of warp dots in the surface layer is 1 to 2 times the number of warp dots in the middle layer.

[0007] Furthermore, in the outer layer, the outer warp and outer weft are interwoven in a three-up-one-down twill pattern; in the middle layer, the inner warp and outer weft are interwoven in a one-up-one-down plain pattern.

[0008] The tight and even plain weave structure of the middle layer enhances the stability of the fabric's middle layer; protected by the bottom and middle layers, the surface layer weave does not need to compromise with napping, and the three-up-one-down twill weave provides the fabric with a complete denim texture.

[0009] Furthermore, the width of the lamp wick strip is greater than the width of the groove.

[0010] Furthermore, the width of the lamp wick strip is 0.1cm to 1cm.

[0011] Furthermore, the width of the lamp wick strip is 0.2cm to 0.5cm.

[0012] Furthermore, the number of branches of the inner meridian is at least 1.5 times the number of branches of the outer meridian.

[0013] A thicker outer warp can effectively cover the middle and bottom layers on the front of the fabric, preventing the inner warp from being seen on the front, thus providing a texture effect similar to traditional denim fabric.

[0014] Furthermore, the number of branches of the inner meridian is 1.5 to 5 times that of the number of branches of the outer meridian.

[0015] Furthermore, the number of branches of the inner meridian is 2.5 to 3.5 times that of the number of branches of the outer meridian.

[0016] Furthermore, the number of branches of the surface is 6S~21S.

[0017] Furthermore, the twist coefficient of the outer weft is 4.5~5.2.

[0018] Furthermore, the inner weft comprises polyester and moisture-absorbing and heat-generating yarns arranged in a 1:1 ratio.

[0019] The beneficial effects of this utility model are as follows: The tear-resistant napped and warm denim fabric of this utility model provides the texture of denim fabric with the surface layer, facilitates the napping process to form a napped layer with a relatively loose bottom layer, and provides a strong interwoven structure with the middle layer to improve the overall strength of the fabric. The corduroy stripes and grooves formed in the bottom layer form corduroy-like stripes and have a similar warmth to corduroy. The interwoven structure of the bottom layer ensures that the fibers of the inner weft are mainly hooked when the bottom layer is napped, without damaging the outer warp or outer weft, and even the inner warp is less damaged. The middle layer is less damaged, and the plain weave structure of the middle layer itself is relatively stable, and the surface layer is undamaged. Therefore, it can effectively improve the tear resistance of the fabric.

[0020] Other features and advantages of this application will be set forth in the following description and will be apparent in part from the description or may be learned by practicing the application. The objectives and other advantages of this application may be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0030] The following disclosure provides many different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or reference letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0031] Reference Figure 1 This application provides a tear-resistant, fleece-lined, warm denim fabric, including a base layer 1. The base layer 1 includes a face warp and an inner warp belonging to two separate systems, as well as a face weft and an inner weft belonging to two separate systems. The face warp and face weft are interwoven in a twill weave to form the surface layer, the inner warp and face weft are interwoven in a plain weave to form the middle layer, the inner warp and inner weft are interwoven to form the bottom layer, and the face warp and inner weft do not interweave. The bottom layer includes grooves and corduroy stripes that alternate along the weft direction. The inner warp that participates in forming the grooves forms weft stitches throughout the entire length of the bottom layer, and the inner warp that participates in forming the corduroy stripes forms warp stitches throughout the entire length of the bottom layer. A fleece-lined layer 11 is provided at the bottom of the base layer 1.

[0032] The robust plain weave structure of the middle layer maintains the surface and bottom layers, inhibiting yarn slippage after brushing. The grooves in the bottom layer slow down airflow and reduce convection, utilizing the high thermal resistance of still air for insulation. The raised corduroy strips are easily hooked up, and the inner warp threads involved in forming the corduroy strips form warp weft points entirely on the bottom layer. In other words, viewed from the reverse side of the process, the corduroy strips are entirely weft threads, so the inner weft threads are mainly sacrificed during brushing, reducing damage to the inner warp threads. This helps to suppress the decrease in strength of the middle layer after brushing. During brushing, the bottom layer is mainly hooked up, and the portion of the yarns involved in forming the middle layer on the bottom layer will be hooked up (less so due to the raised corduroy strips). The surface layer is unaffected, protecting the integrity of the surface layer structure. The middle layer is less damaged, and the plain weave structure of the middle layer itself is relatively stable, effectively improving the fabric's tear resistance after brushing.

[0033] In some embodiments, the number of warp dots in the top layer is 1 to 2 times that in the middle layer. This difference in the number of warp dots makes the middle layer structure more compact, enhances its tear resistance, better maintains the structure of the top and bottom layers, and further improves the overall tear resistance of the fabric.

[0034] In some embodiments, the width of the wick strip is greater than the width of the groove. Smaller grooves help trap air, as the air within the groove does not flow easily, which is beneficial for utilizing the high thermal resistance of still air for insulation. Furthermore, with smaller grooves, the wick strip is primarily felt on the reverse side of the fabric during processing. This reduces the likelihood of the inner warp being caught during napping, minimizing the decrease in mid-layer strength and ensuring that the pile primarily originates from the inner weft. For example, the width of the wick strip is 0.1cm to 1cm. Preferably, the width of the wick strip is 0.2cm to 0.5cm.

[0035] In some embodiments, the thread count of the lining warp is at least 1.5 times that of the outer warp. A coarser outer warp effectively conceals the middle and bottom layers on the fabric's working side, preventing the lining warp from being visible and contributing to a textured effect similar to traditional denim. Specifically, to ensure sufficient strength in the middle layer and to allow for some snagging of the lining warp by the napping machine, the thread count of the lining warp is 1.5 to 5 times that of the outer warp. Preferably, the thread count of the lining warp is 2.5 to 3.5 times that of the outer warp, ensuring the lining warp is not exposed on the outer layer while maintaining a robust middle layer structure.

[0036] As a specific embodiment, refer to Figure 2 In this type of weave diagram, lowercase letters are used for the weft number, uppercase letters for the inner weft number, Chinese numerals for the warp number, and Roman numerals for the inner warp number. Textile professionals understand that in this type of diagram, filled cells represent warp weave points, and unfilled cells represent weft weave points. For example, the fourth column, row d, contains the weft weave points formed by the warp and weft numbers.

[0037] For ease of understanding, Figure 2 Disassemble to obtain Figures 3 to 6 .

[0038] refer to Figure 3 In the surface layer, the warp and weft threads are interwoven in a three-up-one-down twill pattern.

[0039] refer to Figure 4 All of them are warp points, which means that the surface warp is all above the inner latitude, that is, the surface warp and the inner latitude do not intersect.

[0040] refer to Figure 5 In the middle layer, the inner warp and outer weft are interwoven in a plain weave pattern, one up and one down.

[0041] refer to Figure 6 The inner warp of column I forms a groove with the inner weft of rows A, B, C, and D, and the inner warp of columns II to VIII forms a wick strip with the inner weft of rows A, B, C, and D.

[0042] Figure 2 For the minimum tissue cycle, Figure 2 Repeated permutations yield Figure 7From a distance, stripes can be seen running diagonally from the upper right to the lower left, along with alternating dark, thick stripes and light, thin stripes along the horizontal (latitudinal) direction. These vertical stripes reveal the relationship between the wick and the grooves. However, it should be noted that this is only a "revelation," not an actual product pattern, because the wick stripes are located on the back of the process, while the diagonal stripes are on the front.

[0043] The thread count of the outer warp can range from 6S to 21S. This thread count range allows for a reasonable match with a finer inner warp, ensuring the strength and abrasion resistance of the fabric surface while providing the fabric with appropriate thickness and softness to meet the requirements of wearing comfort. It also helps maintain the stability of the overall fabric structure and improves tear resistance.

[0044] Specifically, the twist coefficient of the outer weft is 4.5~5.2. High twist outer weft provides better strength and toughness. The outer weft participates in the formation of the face layer and middle layer, improving the overall strength of the fabric and inhibiting tearing.

[0045] Polyester is a commonly used yarn in fleece fabrics, which has good warmth retention, but its moisture absorption is poor, with a moisture regain rate of about 0.4%, which can easily cause a stuffy feeling. Although it is warm, it is not comfortable enough. Once sweat is produced, it is difficult to wick away, which can easily breed bacteria and thus affect the comfort of wearing it.

[0046] Preferably, the weft yarn comprises polyester and moisture-absorbing and heat-generating yarn arranged in a 1:1 ratio. The polyester can be antibacterial treated polyester, and the moisture-absorbing and heat-generating yarn is moisture-absorbing and heat-generating nylon. Both are existing products. When these two yarns are arranged in a 1:1 ratio as the weft yarn, the moisture-absorbing and heat-generating yarn absorbs moisture emitted by the human body to generate heat, reducing stuffiness and providing warmth. Combined with the insulation of polyester and the inhibition of bacterial growth, this contributes to providing a more comfortable warmth.
