Description

Technical Field

[0001] The utility model relates to a comfortable and warm ribbed velvet denim fabric, belonging to the field of textiles. Background Art

[0002] Traditional denim fabrics are made of pure cotton warp yarns dyed with indigo dye and white weft yarns interwoven in a twill structure. They are popular for their tight, twill and retro style. Based on the characteristics of indigo dye itself, after the denim clothing is washed, part of the indigo dye on the fiber is faded, allowing denim clothing to present a variety of vintage styles, becoming an irreplaceable and important role in the clothing market.

[0003] Although traditional denim clothing is relatively thick, its warmth retention effect is average, so technicians have developed a variety of denim fabrics with warmth retention effects. For example, yarn with a heating effect is used as the weft yarn for weaving, so that the fabric has functional effects such as far infrared and heating. It is still effective after long-term use, but the warmth retention is not obvious. For another example, some technicians have developed composite denim fabrics, which are glued to the denim fabric and the fluff, so that the bottom surface of the denim fabric has a layer of fluff. However, after long-term use, the aging of the glue will make the composite fabric gradually become stiff. Moreover, the viscosity of the glue decreases after aging, and the fluff falls off during washing and entangles with the fluff that has not fallen off, forming a wavy bulge, which affects the comfort of wearing.

[0004] Some existing technicians have designed denim fabrics into double-layer fabrics, with the surface weft and the inner warp interwoven to form a junction, and the inner weft forms a floating line on the bottom surface, which is used to pull the fabric bottom surface to make the fabric bottom surface present a layer of fluff. However, the fluff is mainly formed by the fibers in the floating line being hooked and pulled out. Although the resulting fluff is long, it is not dense enough. After the fabric is stretched, the fluff will become very sparse; moreover, after the fluff is pulled out, the inner weft part is hooked out of the fluff, and a lot of the surface weft and the inner warp are also hooked out of the fluff, which greatly reduces the strength of the fabric. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a comfortable and warm ribbed velvet denim fabric, which has high fabric strength and the velvet remains dense after stretching, thereby achieving a long-term warming effect.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A comfortable and warm ribbed denim fabric, with a fleece layer on the bottom surface, the fabric comprising two systems of warp yarns and two systems of weft yarns, the warp yarns are divided into surface warps and inner warps, the weft yarns are divided into surface wefts and inner wefts, the surface wefts and the inner wefts are interwoven with the inner warp in plain weave, the surface warp and the surface weft are interwoven in twill weave, the surface warp and the inner weft are not interwoven, the inner weft is thicker than the surface weft, the inner weft is multifilament, and the shrinkage rate of the surface weft is greater than the shrinkage rate of the inner weft.

[0008] The comfortable and warm ribbed denim fabric provided by the present application does not need to form floating long lines on the bottom surface, but uses thicker multifilaments as the inner weft, which is matched with the surface weft with a larger shrinkage rate. Under the action of the surface weft shrinking and tightening the fabric, the surface weft is pulled into the inside of the fabric, so that the thicker inner weft appears to expand and bulge downward, and can cover the surface weft. The fleece raising layer is mainly provided by the inner weft. The damage to the surface warp and the surface weft during the formation of the fleece raising layer is relatively small, and the surface weft and the inner weft are interwoven with the inner warp in plain weave, so that the bottom layer of the fabric is relatively tight, and the effect of the surface weft tightening the fabric makes the fabric stronger. In addition, since the bottom surface of the fabric is plain weave, it does not rely on floating long lines for raising the fleece, and the inner weft is a thicker multifilament, the fleece raising layer has short and numerous, very dense, and is more comfortable when in contact with the skin. The shorter fleece is not easy to tangle and form bulges. When the fabric is stretched within a certain range, it is only equivalent to reducing the expansion and bulge of the inner weft on the bottom surface, so the fleece will not become significantly sparse.

[0009] In a preferred spinning implementation, the surface warp and the surface weft are interwoven in a three-up-one-down twill, so that the surface of the fabric presents the texture of denim fabric.

[0010] In a preferred spinning implementation, the surface warp is thicker than the inner warp, so that the surface warp can cover the inner warp on the front side of the fabric.

[0011] Furthermore, the count of the lining warp is more than three times the count of the surface warp, which is beneficial for showing the twill on the front side of the fabric without revealing the plain weave of the bottom layer of the fabric.

[0012] Furthermore, the number of threads of the inner warp is three to eight times the number of threads of the outer warp.

[0013] Furthermore, the count of the surface warp is 8S-32S.

[0014] In the preferred spinning implementation, the F number of the inner weft is 114F-900F. The F number is also called the strand number, which is used to indicate how many single fibers a chemical fiber multifilament is composed of. The inner weft with a high F number can form a lot of fluff when it is piled and raised. With the plain weave structure, the short and numerous fluff will not become sparse when the fabric is stretched.

[0015] Furthermore, the denier of the single fiber of the lining is 80D-500D, and after being fleeced and raised, fine and soft fluff can be formed, making the fabric more comfortable when in contact with the skin.

[0016] Furthermore, the count of the surface weft is 21S-60S, which is conducive to the inner weft with high F number and high denier to cover the surface weft on the bottom surface of the fabric while ensuring that the surface weft provides sufficient shrinkage effect.

[0017] In the preferred spinning implementation, the same inner warp and each of the surface wefts have the same type of organization points, and the same inner warp and each of the inner wefts have the same type of organization points; and on the same inner warp, the type of organization points formed by the surface weft is always opposite to the type of organization points formed by the inner weft, so that the bottom surface of the fabric has vertical stripes similar to corduroy before it is fleeced and raised, and the fabric has better stability, and can have a stronger warming effect after the fleece layer is formed.

[0018] The beneficial effects of the utility model are as follows: the comfortable and warm ribbed velvet denim fabric of the utility model is stretched toward the inside of the fabric under the action of the surface weft shrinking and tightening the fabric, so that the weft tissue points of the thicker inner weft appear to expand and bulge downward, which can cover the surface weft, and the damage to the surface warp and surface weft during the formation of the fleece raising layer is small, and the surface weft and the inner weft are interwoven with the inner warp in plain weave, so that the bottom layer of the fabric is relatively tight, and the surface weft tightens the fabric, so the overall strength of the fabric is relatively high; in addition, since the bottom surface of the fabric is plain weave, it does not rely on floating long lines for raising the fleece, and the inner weft is a thicker multifilament, the fleece of the fleece raising layer is short and numerous, fine and dense, and is more comfortable when in contact with the skin. When the fabric is stretched within a certain range, it is only equivalent to reducing the expansion and bulging degree of the inner weft on the bottom surface, so the fleece will not become significantly sparse.

[0019] Other features and advantages of the present application will be described in the following description, and partly become apparent from the description, or understood by practicing the present application. The purpose and other advantages of the present application can be realized and obtained by the structures particularly pointed out in the written description and the drawings.

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0029] Reference Figure 1 The embodiment of the present application provides a comfortable and warm ribbed denim fabric, including two systems of warp yarns and two systems of weft yarns, the warp yarns are divided into surface warp 10 and lining warp 30, the weft yarns are divided into surface weft 20 and lining weft 40, the surface weft 20 and lining weft 40 are interwoven with lining warp 30 in plain weave, the surface warp 10 and the surface weft 20 are interwoven with twill weave, the surface warp 10 and the lining weft 40 are not interwoven, the lining weft 40 is thicker than the surface weft 20, the lining weft 40 is multifilament, and the shrinkage rate of the surface weft 20 is greater than the shrinkage rate of the lining weft 40. Among them, the surface warp 10 and the surface weft 20 are interwoven into the surface layer of the fabric, the lining warp 30 and the lining weft 40 are interwoven into the bottom layer of the fabric, and the bottom surface of the bottom layer is subjected to fleece treatment to obtain the fleece layer 50.

[0030] The embodiment of the present application adopts a new type of organizational structure and sets it in combination with yarn, so that the inner weft can cover more of the bottom layer of the fabric, and a layer of fluff is formed on the bottom surface after the fleece process, so as to achieve a comfortable and warm effect. Specifically, the strength of the fabric is still high after fleece is fleeced, and the formed fluff is dense, and it will not become significantly sparse after the fabric is stretched.

[0031] The principle of the fabric's strength remaining high after fleece-raising:

[0032] (1) In the prior art, fleece-finished fabrics usually form a large number of floating long lines on the bottom surface of the fabric, so the inner weft and warp yarns are less interwoven; in the embodiment of the present application, the surface weft 20 and the inner weft 40 are interwoven with the inner warp 30 in a plain weave, with many interweaving points and a tight fabric structure.

[0033] (2) The surface weft 20 has a tightening effect on the fabric.

[0034] (3) The inner weft 40 is thicker than the outer weft 20. The shrinkage rate of the outer weft 20 is greater than that of the inner weft 40. The outer weft 20 is tightened toward the inside of the fabric (between the surface layer and the bottom layer), making the thicker inner weft 40 bulge downward (bottom surface), which can cover the outer weft 20. When the fleece is raised, the inner weft 40 is mainly damaged.

[0035] (4) The inner weft 40 is a multifilament yarn. After being plucked, some single fibers are disconnected, but there are still many single fibers to maintain the strength of the bottom layer.

[0036] The principle of dense pile and no significant thinning after stretching the fabric:

[0037] (1) In the prior art, fleece-pulled fabrics usually form a large number of floating long lines on the bottom surface of the fabric, and the resulting fleece is long and sparse; in the embodiment of the present application, the surface weft 20 and the inner weft 40 are interwoven with the inner warp 30 in a plain weave, and the resulting fleece is short and numerous.

[0038] (2) The inner weft 40 is a multifilament yarn containing multiple single fibers that can be hooked.

[0039] (3) The shrinkage rate of the surface weft 20 is greater than that of the inner weft 40, which reserves a stretch margin for the fabric. When the fabric is stretched within a certain range, it is only equivalent to reducing the expansion and protrusion of the inner weft 40 on the bottom surface, so the fluff will not become significantly sparse.

[0040] Reference Figure 2 The embodiment shown in the figure shows the structure of a comfortable and warm ribbed denim fabric in a specific embodiment. Figures 2 to 6 In the figure, Arabic numerals are used to represent the serial number of the outer warp, Roman numerals are used to represent the serial number of the inner warp, capital letters are used to represent the serial number of the inner weft, and lowercase letters are used to represent the serial number of the outer weft. As a drawing convention in this field, the grids filled with shades represent the warp points (from the front of the process), and the grids without shades represent the weft points (from the front of the process). For example, the interweaving point of the D-th row weft yarn and the II-th column warp yarn is the warp point formed by the inner weft and the inner warp. If viewed from the back of the process, this point is the weft point.

[0041] from Figure 2 Decompose the organizational structure formed by the inner warp and outer weft to obtain Figure 3 ;from Figure 2Decomposing the organization structure formed by the inner warp and inner weft, we get Figure 4 ;from Figure 2 Decompose the organizational structure formed by the surface warp and surface weft to obtain Figure 5 ;from Figure 2 Decomposing the organizational structure formed by the outer warp and the inner weft, we get Figure 6 .from Figure 6 It can be seen that all of them are warp points, that is, the outer warp is only "overlapped" on the inner weft, and the outer warp and the inner weft are not intertwined, which is consistent with Figure 1 All the middle latitudes 40 correspond to the surface longitude 10.

[0042] like Figure 5 As shown, the surface warp 10 and the surface weft 20 are interwoven in a three-up and one-down twill, so that the surface of the fabric presents the texture of denim fabric. Specifically, both the surface warp and the inner warp can be pure cotton warp yarns dyed with indigo or sulfur black to avoid the bottom layer from being visible on the front of the fabric.

[0043] In addition, the configuration of the yarn can also prevent the white bottom layer from being visible on the front of the fabric. For example, the outer warp 10 is thicker than the inner warp 30, so that the outer warp can cover the inner warp on the front of the fabric. Specifically, the count of the inner warp 30 is more than three times the count of the outer warp 10, which is conducive to showing the twill on the front of the fabric and not revealing the plain weave of the bottom layer of the fabric. More preferably, the count of the inner warp 30 is three to eight times the count of the outer warp 10. At the same time, the count of the outer warp 10 is 8S-32S, which can show the appearance of the surface of conventional denim.

[0044] The multifilament contains multiple single fibers, and the F number represents the number of single fibers contained in a multifilament. Preferably, the F number of the inner weft 40 is 114F-900F. The inner weft with a high F number can form a lot of fluff when it is fleeced and raised. With the plain weave structure, the short and numerous fluffs will not become obviously sparse when the fabric is stretched. More preferably, the denier of the single fiber of the inner weft 40 is 80D-500D. After fleecing and raising, it can form fine and soft fluff, making the fabric more comfortable when it touches the skin. Correspondingly, the count of the surface weft 20 is 21S-60S, which can be well covered by the multifilaments of 80D-500D and 114F-900F.

[0045] At the same time, the surface weft is also used to connect the surface layer and the inner layer of the fabric. When configuring the yarn, the surface weft is slightly thinner than the surface warp, which is beneficial to the fabric process so that the bottom layer of the fabric is not easily visible from the front. Specifically, the surface weft can be a polyester-nylon composite yarn. After the washing treatment required by denim fabrics, the surface weft can obtain a better shrinkage effect. Of course, other yarns with stronger shrinkage can also be used for the surface weft.

[0046] Preferably, refer to Figure 3 and Figure 4The same inner warp 30 has the same type of organization points as each surface weft 20, and the same inner warp 30 has the same type of organization points as each inner weft 40; and on the same inner warp 30, the type of organization points formed by the surface weft 20 is always opposite to the type of organization points formed by the inner weft 40.

[0047] although Figure 3 and Figure 4 It seems that a single inner warp has no interweaving relationship with a certain weft yarn, but because the type of weaving point formed by the surface weft 20 on the same inner warp 30 is always opposite to the type of weaving point formed by the inner weft 40, and the surface weft and the outer warp are interwoven in twill, the fabric structure is stable and will not fall apart. And because the same inner warp 30 has the same weaving point type as each outer weft 20, and the same inner warp 30 has the same weaving point type as each inner weft 40, under the stretching of the surface weft contraction, the inner weft expands and bulges downward, and the bottom surface of the fabric will form vertical strip-shaped bulges similar to corduroy before the fleece is plucked, obtaining a corduroy-like warmth-keeping effect, and coupled with the fleece-raising layer 50 formed by the fleece, the fabric can obtain a stronger warmth-keeping effect.

These improvements and modifications are also considered to be within the protection scope of the present invention.
