[0032] With the improvement of people's consumption level and the change of consumption concepts, people are pursuing the comfort of denim clothing fabrics more and more. Four-way stretch denim fabrics with elasticity in both warp and weft directions are popular among consumers. However, the edges of four-way stretch fabrics are prone to unevenness due to elastic shrinkage, causing the edges to curl or become lotus-shaped. Lightweight four-way stretch denim is especially prone to this problem. If the edges of the fabric curl or become lotus-shaped, it will bring great difficulties to dyeing and finishing, as well as to cutting and sewing. This application improves the warp yarn of the four-way stretch fabric and obtains a four-way stretch fabric with smooth edges through a special fabric body and sewing design, which greatly improves the user experience of the four-way stretch fabric.

[0033] In order to more clearly illustrate the structure of the four-way stretch fabric, the four-way stretch fabric will be introduced below with reference to the accompanying drawings.

[0034] See also Figure 1 , Figure 1 This is a fabric pattern diagram of a four-way stretch fabric provided in one embodiment of the present application. The grid marked with "x" represents the warp weave point 100 of the fabric body, indicating that the warp yarns float above the weft yarns in the warp and weft yarns that intersect here; The grid with " represents the warp weave point 200 of the selvedge, indicating that the warp yarn floats above the weft yarn in the warp and weft yarns intersecting at this point; the weft weave point 300 is a blank grid, indicating that the weft yarn floats above the warp yarn in the warp and weft yarns intersecting at this point.

[0035] One embodiment of the present application provides a four-way stretch fabric. The four-way stretch fabric is woven using a first warp yarn, a second warp yarn, and a weft yarn. The first warp yarn is a non-elastic yarn, the second warp yarn has greater elasticity than the first warp yarn, and the weft yarn is an elastic core-spun yarn. The four-way stretch fabric includes a fabric body and a selvedge disposed at the weft edge of the fabric body. The first warp yarns and the second warp yarns in the fabric body are alternately arranged in a 1:1 ratio. The ratio of the number of the first warp yarns to the second warp yarns in the selvedge is (1.2-2):1.

[0036] In the present application, the first warp yarns and the second warp yarns are arranged alternately in a 1:1 ratio in the body of a four-way stretch fabric, which is conducive to obtaining a fabric with a more uniform and comfortable hand. Increasing the proportion of the first warp yarns, which have lower elasticity, in the selvedge of the four-way stretch fabric is conducive to improving the smoothness of the selvedge of the four-way stretch fabric. However, excessive use of the first warp yarns can also lead to a poor hand feel and a significant decrease in elasticity of the four-way stretch fabric. Controlling the ratio of the first warp yarns to the second warp yarns to (1.2-2):1 is conducive to obtaining a four-way stretch fabric with both good hand feel, high elasticity, and a relatively smooth surface.

[0037] In some embodiments, the second warp yarn is a chemical fiber stretch yarn, which is polyester or a blended yarn containing polyester.

[0038] In some embodiments, the size of the chemical fiber stretch yarn is 20D-110D. The size of the chemical fiber stretch yarn includes but is not limited to: 20D, 30D, 40D, 50D, 60D, 70D, 80D, 90D, 100D, 110D or other parameters.

[0039] In some embodiments, the yarn count of the first warp yarn is 8S to 32S. The yarn count of the warp yarn includes but is not limited to: 8S, 12S, 16S, 20S, 24S, 28S, 32S or other parameters.

[0040] In some embodiments, the core of the elastic core-spun yarn is elastic filament, the draft ratio is 2.5 to 4.5 times, and the covering layer of the elastic core-spun yarn is a blended yarn made of polyester fiber and viscose fiber.

[0041] In some embodiments, the yarn count of the elastic core-spun yarn is 8S to 32S. The yarn count of the elastic core-spun yarn includes but is not limited to: 8S, 12S, 16S, 20S, 24S, 28S, 32S or other parameters.

[0042] In some embodiments, the core yarn of the elastic core-spun yarn has a specification of 20D to 110D. The specifications of the core yarn of the elastic core-spun yarn include but are not limited to: 20D, 30D, 40D, 50D, 60D, 70D, 80D, 90D, 100D, 110D or other parameters.

[0043] In some embodiments, in the fabric body of the four-way stretch fabric, a first twill weave is formed between the weft yarns and the first warp yarns, and a second twill weave is formed between the weft yarns and the second warp yarns.

[0044] In some embodiments, the first twill weave and the second twill weave are selected from common twill weave structures, such as three-up, one-down, one-up, four-up, two-down, and other twill weaves. The first twill weave and the second twill weave can be the same twill weave. For example, the first twill weave and the second twill weave are both three-up, one-down. The first twill weave and the second twill weave can also be different twill weaves, for example, the first twill weave is a three-up, one-down twill weave, and the second twill weave is a one-up, one-down twill weave. By providing different combinations of the first and second twill weaves, a variety of twill textures can be obtained.

[0045] In some embodiments, the weave structure of the selvedge of a four-way stretch fabric includes one of a plain weave and a double warp weave. The selvedge weave employs a weave with the same number of warp and weft floats on both sides, which balances the relaxation stress on both sides of the selvedge, thereby alleviating the curling problem. Furthermore, due to the low number of warp and weft floats (1-2), the fabric structure is relatively compact, resulting in greater retraction resistance of the stretch yarn and less shrinkage, effectively alleviating the curling problem.

[0046] In some embodiments, the fabric edge includes a first buffer zone, a stabilizing zone, and a second buffer zone. The stabilizing zone is located between the first and second buffer zones, and the fabric edge is connected to the fabric body via the first buffer zone. The warp yarns of the stabilizing zone are the first warp yarns, and the warp yarns of both the first and second buffer zones are formed by alternating first and second warp yarns in a 1:1 ratio. The number of warp yarns in the first and second buffer zones is an even number.

[0047] By adjusting the structure of the fabric edge, the curling problem of the fabric can be alleviated to a certain extent. In order to further improve the curling problem of the fabric, the present application sets the fabric edge as a combination of a first buffer band, a stabilizing band and a second buffer band, which can reduce the number of first warp yarns used while reducing the curling degree of the fabric edge, so as to obtain a four-sided stretch fabric with both comfortable hand feel and smooth fabric edges.

[0048] In some embodiments, the number of first warp yarns in the stabilizing band is 3 to 15. The first warp yarns are non-elastic yarns, and by continuously arranging 4 to 12 first warp yarns to form a stabilizing band, curling of the selvedge caused by elastic retraction of the selvedge can be effectively reduced.

[0049] In some embodiments, in the first buffer zone, the number of combinations of the first warp yarns and the second warp yarns is 4 to 14 groups.

[0050] In some embodiments, in the second buffer zone, the number of combinations of the first warp yarns and the second warp yarns is 14 to 24.

[0051] The number of warp yarns in the first and second buffer zones should not be too high, otherwise the stabilizing band will not be able to effectively suppress the curling of the selvedge. If the number of first and second warp yarns in the first and second buffer zones is too small, the selvedge's performance will be more susceptible to the stabilizing band, resulting in reduced elasticity and a poorer feel. By controlling the number of first and second warp yarn repetitions between 5 and 17, a smooth, comfortable, and stretchy selvedge can be achieved.

[0052] In some embodiments, the number of warp yarns in the cloth body is 5000 to 9000, and the number of warp yarns in the selvedge is 100 to 200.

[0053] In some embodiments, the warp density is 70 to 130 yarns / inch. Warp density includes but is not limited to: 70 yarns / inch, 80 yarns / inch, 90 yarns / inch, 100 yarns / inch, 19 yarns / inch, 120 yarns / inch, 130 yarns / inch or other parameters.

[0054] In some embodiments, the weft density is 40 to 100 yarns / inch. The weft density includes but is not limited to 40 yarns / inch, 50 yarns / inch, 60 yarns / inch, 70 yarns / inch, 80 yarns / inch, 90 yarns / inch, 100 yarns / inch or other parameters.

[0055] In one embodiment of the present application, a method for preparing the above-mentioned four-way stretch fabric is also provided.

[0056] The method for preparing a four-way stretch fabric includes piece-dyeing a first warp yarn and sizing a second warp yarn. The fabric is then threaded through a reed according to a predetermined weave structure of the selvedge and body to produce a grey fabric. The grey fabric is then subjected to post-finishing, which may include one or more of singeing, desizing, fleecing, skewing, and shrink-proofing.

[0057] In some embodiments, air interlacing texturing technology is used to prepare chemical fiber stretch yarns. The covering filaments and spandex filaments are simultaneously drawn through a nozzle of a certain size, and the yarns are formed into a rhythmic interlaced yarn by regular spraying of highly compressed air.

[0058] In some embodiments, before the first warp yarn is piece-dyed and the second warp yarn is sizing, the first warp yarn and the second warp yarn are further wound and warped. The first warp yarn and the second warp yarn are respectively wound on two warp beams according to a set length and width by a warping machine.

[0059] In some embodiments, the first warp yarn is dyed with indigo dye or sulfur dye.

[0060] In some embodiments, the second warp yarn is sized by dipping it in a treatment solution, the sizing tank temperature is 85°C to 95°C, and the sizing machine speed is 5m / min to 8m / min. The sizing solution includes starch, PVA, and a cationic antistatic agent. The cationic antistatic agent includes amine salts and quaternary ammonium salts. The concentration of the cationic antistatic agent is 7g / L to 10g / L, and the starch is 60kg / m 3 ~70kg / m 3 , PVA 40kg / m 3 ~60kg / m 3 The addition of antistatic agent can make the yarn sheets evenly and clearly arranged after sizing, which is beneficial to improve the reeding efficiency and effectively prevent the second warp yarn from entanglement during the weaving process.

[0061] In some embodiments, the piece-dyed first warp yarns are sized in the same manner as the second warp yarns.

[0062] In some embodiments, the warp yarns of the cloth body are drawn in as follows: the first warp yarn is drawn in the 1st, 3rd, 5th and 7th heald frames, and the second warp yarn is drawn in the 2nd, 4th, 6th and 8th heald frames. The warp yarns of the selvedge are drawn in as follows: the first warp yarn is drawn in the 9th heald frame, and the second warp yarn is drawn in the 10th heald frame.

[0063] In some embodiments, a double-warp-beam rapier loom is used for weaving, with the lower warp carrying the first warp yarn and the upper warp carrying the second warp yarn. The fabric is threaded through the reed according to the designed selvedge and body combination. The threaded creel is then transferred to the loom for weaving into the greige fabric. The weaving speed is 300-400 r / min, the threading number of reeds is 4, the back beam height is 2-4 mm, and the shedding time is 305-315 degrees.

[0064] In some embodiments, the front side of the fabric is singed once, with a flame temperature of 1000°C to 1200°C and a machine speed of 70m / min to 100m / min. The second warp yarn is a synthetic stretch yarn that is not resistant to high temperatures, so a lower singeing temperature and a faster machine speed are required.

[0065] In some embodiments, enzymatic desizing is used for desizing, wherein the desizing temperature is 50° C. to 60° C., the treatment time is 2 min to 5 min, and the concentration of the desizing enzyme is 1 g / L to 5 g / L.

[0066] In some embodiments, the grey fabric is fleeced once, the drum speed is 6 rpm to 12 rpm, and the fleece needle gripping force is 0.5 N to 1 N. Fleecing the fabric can relax the fabric stress, reduce elastic retraction, and increase the softness of the fabric.

[0067] In some embodiments, the tentering temperature is 100° C. to 150° C., and the tentering speed is 30 m / min to 45 m / min. The tentering treatment is performed in a loose and low-tension state to ensure the appearance of the fabric.

[0068] In some embodiments: a pre-shrinking machine is used for shrinkage prevention, the moisture content of the fabric is 15% to 20%, the vehicle speed is 15 m / min to 30 m / min, the compression degree of the rubber blanket is 10% to 20%, and the temperature is 100° C. to 150° C.
