Description
TECHNICAL FIELD
[0001] The utility model relates to the field of textile, more particularly to a kind of jean fabric. BACKGROUND
[0002] Most jean fabrics on the market adopt twill weave to interweave warp and weft yarns, but because the density of twill weave is high, the jean fabric will be hard, so the air permeability of the jean fabric is relatively poor, and because twill weave is adopted, the jean fabric is prone to weft skew after washing. SUMMARY
[0003] The utility model aims at overcoming the shortcomings of the prior art, and provides a jean fabric, which is formed by the combination of the weave of interwoven warp and weft yarns and the float line formed by non-interwoven warp and weft yarns, changes the conventional interweaving of warp and weft yarns, slightly arches the float line through the design of the float line, so that a small gap is formed on the surface of the fabric, and because the float line is combined with the interweaving, the average density of the overall fabric is reduced, so the air permeability of the jean fabric is improved, and because the float line is not interwoven, the warp and weft yarns will not be inactivated due to the pressure from above and below, so the warp and weft yarns between the float line are relatively free, so when the jean fabric is subjected to external force, the warp and weft yarns at the float line can freely extend with the external force, so the elasticity and elastic recovery of the fabric are improved, and because the float line improves the elasticity and elastic recovery of the fabric, the jean fabric will not be skewed after washing, and the interwoven part of the warp and weft yarns forms concave-convex, and the interweaving and the float line are alternately arranged, so that the float line will not be easily broken due to being too long, and the interweaving and the float line increase the dimensional stability of the fabric.
[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a jean fabric, which comprises a first area, a second area and a third area, the first area and the second area are alternately arranged along the width direction of the fabric, the first area and the second area are alternately arranged along the length direction of the fabric, in the square area surrounded by two oblique first areas and two oblique second areas, the third area is located in the middle of the two first areas and the two second areas, the fabric takes 56 warps and 72 wefts as one cycle, each first area is formed by 23 warps and 39 wefts without interweaving, each second area is formed by 33 warps and 33 wefts interweaving, and each third area is formed by 5 warps and 7 wefts interweaving.
[0005] The utility model is further provided with the second area comprising a recessed area and a raised area, each second area comprises 3 recessed areas and 2 raised areas, and the recessed areas and the raised areas are alternately arranged along the length direction of the fabric.

[0010] Summarized above, the utility model has following beneficial effect:
[0011] Through warp and weft yarn interweave and not interweave, interweave and form concave-convex surface, not interweave and form float, because the density of interweave is higher than float, therefore float will slightly arch, thereby form tiny gap on the surface of fabric, and interweave and not interweave combination, make average density reduce, thereby increase the air permeability of fabric while increasing the softness of fabric, and because the existence of float, warp and weft yarn of float do not press each other, therefore warp and weft yarn of float are relatively free, therefore when fabric is subjected to external force, warp and weft yarn of float will change along with the change of external force, make fabric increase elasticity and elastic recovery, and the gap between float can relieve the tightness between warp and weft yarn of interweave, thereby make fabric not appear weft skew, and the concave-convex of interweave and the alternate arrangement of float reduce the hooking and breaking phenomenon of float, increase the structural stability of fabric.

[0015] Sign significance: first area 80, second area 90, recessed area 901, protruding area 902, third area 100. Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] This embodiment discloses a denim fabric, including a first region 80, a second region 90, and a third region 100. The fabric is formed by 56 warp yarns and 72 weft yarns in a cycle. Each first region 80 is formed by 23 warp yarns and 39 weft yarns without interlacing. Each second region 90 is formed by 33 warp yarns and 33 weft yarns interlacing. Each third region 100 is formed by 5 warp yarns and 7 weft yarns interlacing. Warp yarns 1-22 and weft yarns 1-39, and warp yarns 29-51 and weft yarns 1-3 and 37-72 form the first region 80. After the warp and weft yarns interlac, the first region 80 forms a floating area. Because the warp and weft yarns do not interlac, they do not press against each other, thus forming tiny gaps on the fabric surface. When the fabric is used, moisture can be released through these gaps, improving the fabric's breathability. Furthermore, because the floating yarns in the first region 80 reduce the interlacing frequency of the warp and weft yarns, the fabric becomes softer.
[0018] The first 28 warp yarns interweave with the 40th to 72nd weft yarns, and the 24th to 56th warp yarns interweave with the 4th to 36th weft yarns to form a second region 90. Therefore, the second region 90 after the warp and weft yarns interweave includes recessed areas 901 and raised areas 902. Each second region 90 includes three recessed areas 901 and two raised areas 902, and the recessed areas 901 and raised areas 902 are arranged alternately along the length of the fabric. The recessed areas 901 and raised areas 902 are of equal size. (Refer to...) Figure 3Because the second area 90 is arranged alternately in a concave-convex structure, and the warp yarn floats and the weft yarn floats in the concave area 901 and the convex area 902 are both 3:3 and 2:2, in the second area 90, the softness of the fabric is increased by different float lengths, and because of the existence of the concave area 901 and the convex area 902, the warp and weft yarns are intertwined and remain concave-convex, so that the warp and weft yarns are bent, so that when the fabric is subjected to external force, the bending can buffer the external force, thereby maintaining the shape of the fabric, and because the warp yarn floats and the weft yarn floats in the concave area 901 and the convex area 902 are the same, the warp yarn floats and the weft yarn floats are alternately arranged, so that the distance between the warp yarn and the weft yarn is the same, thereby increasing the structural stability of the second area 90, and because the second area 90 forms the concave area 901 and the convex area 902, because of the existence of the concave-convex, the contact area of the second area 90 is reduced, and because the concave-convex forms a certain distance, thereby increasing the air permeability of the fabric.
[0019] The 24th-28th warp yarns and the 1st-5th, 35th-41st, and 71st-72nd weft yarns are intertwined to form a third area 100, and the 52nd-56th warp yarns and the 1st-5th, 35th-41st, and 71st-72nd weft yarns are intertwined to form a third area 100. Because the first area 80 is all floats, the warp yarn floats and the weft yarn floats in the second area are equal, and in the third area 100, in addition to the warp yarn floats in the second area 90, the rest are all twills, and the floats of the twills form a ladder shape, and in the square area surrounded by two first areas 80 and two second areas 90, the third area 100 is located in the middle of the two first areas 80 and the two second areas 90, so that the third area 100 is intertwined to form a firm chain structure, so that when the first area 80 is connected, and the third area 100 increases one limit at the floats on both sides of the first area 80, the floats of the first area 80 can move slightly within the first area 80 under the action of external force, but will not exceed the two sides, so that the first area will not be deformed, further maintaining the dimensional stability of the fabric, when the second area 90 is connected, four inclined edges are added at the four corners of the square second area 90, forming a triangular fixation, so that the area where the third area 100 is located, the weft yarn floats of the two second areas 90 will not be broken because they are too long, and the dimensional stability of the second area 90 is stabilized.
[0020] The first area 80, the second area 90 and the third area 100 are formed simultaneously, so along the width direction of the fabric, the first area 80 and the second area 90 are arranged alternately, along the length direction of the fabric, the first area 80 and the second area 90 are arranged alternately, and the second area 90 and the third area 100 are both interlaced, and because the first area 80, the second area 90 and the third area 100 are formed simultaneously, in the case of interlacing of the second area 90 and the third area 100, because of the density relationship, the first area 80 is formed with a slight arch, which can increase the air permeability of the fabric, the second area 90 is formed with concave-convex, and the third area 100 is formed with twill, so when an external force is applied, the floats of the first area 80 are stretched from arching, and the second area 90 is straightened from concave-convex, so that the fabric can increase the elasticity, and because the floats of the first area 80 are not interlaced, when the external force is lost, the floats will not easily deform, and because of the shape retention of the yarns of the second area 90, the fabric has good elastic recovery, and because the first area 80 and the second area 90 are arranged alternately, the interlacing and the floats are also arranged alternately, so the floats will form a partition under the pressure of the interlaced stitches, and will not always be floats, so that the floats in the first area 80 will not easily appear the phenomenon of hooking and breaking due to being too long, and the alternately arranged first area 80 and second area 90 reduce the deformation and wear of the fabric, thereby optimizing the structural stability of the fabric.
[0021] Because the width M of the second area 90 is greater than the width H of the first area 80, the length N of the second area 90 is less than the length L of the first area 80, and the convex height of the first area 80 is consistent with the convex height of the convex area 902, because the float yarns of the first area 80 are all warp float yarns on the front surface of the fabric, and the float yarns of the first area 80 are all weft float yarns on the back surface of the fabric, therefore the length N of the second area 90 is less than the length L of the first area 80, because the second area 90 is arranged alternately in concave and convex, so as to adapt to the external force in multiple directions, therefore when the front surface of the first area 80 is subjected to an external force, it can be stretched as much as possible along the length direction of the fabric, so as to increase the elasticity and elastic recovery in the longitudinal direction, and when the back surface of the first area 80 is subjected to an external force, it can be stretched as much as possible along the width direction of the fabric, so as to increase the elasticity and elastic recovery in the transverse direction, and because the third area 100 is interlaced between the first area 80 and the second area 90, and the warp float yarns and weft float yarns of the first area 80 and the second area 90 are different from those of the third area 100, therefore the tightness of the third area 100 is the tightest, so as to stabilize the first area 80 and the second area 90, and because the first area 80 is a float yarn, therefore there is a gap between the warp and weft yarns of the first area 80, therefore when the second area 90 and the third area 100 are subjected to an external force or washing, the warp and weft yarns between the second area 90 and the third area 100 can have a buffer place, and the second area 90, the third area 100 and the first area 80 restrict each other, therefore after the warp and weft yarns are interlaced to form the fabric, the first area 80, the second area 90 and the third area 100 complement each other, so as to reduce the displacement of the warp and weft yarns due to washing, and reduce the weft skew phenomenon of the fabric.

It should be noted that, for ordinary skilled in the art, some improvements and decorations without departing from the principles of the present application shall also be considered as falling within the protection scope of the present application.
