Description

Technical Field

[0001] This invention relates to the field of textile technology, and in particular to a woven label with cut edges, its preparation method, and the fabric thereof. Background Technology

[0002] Woven labels are trademarks sewn onto fabrics such as clothing and trousers, typically containing text, letters, logos, or other designs. They are made using a woven label machine, where the warp yarns are fixed while the weft yarns express text, graphics, letters, numbers, three-dimensional symbols, color combinations, etc. Classified by manufacturing method, woven labels can be divided into cut-edge woven labels and woven-edge trademarks. Cut-edge woven labels are made by first weaving the fabric, then heat-cutting it into strips according to width requirements, and finally cutting it into appropriately sized trademarks using a shearing and folding machine. Cut-edge woven labels can display up to eight colors; their dimensions can be customized to customer needs; and they are highly efficient.

[0003] Hot cutting utilizes the melting property of fibers to make polyester yarns stick together during the hot cutting process, preventing them from fraying. However, this can easily cause the cut edge of the woven label to melt into a single piece. After cooling, the cut edge of the woven label will harden and easily scratch the skin. Woven labels are also prone to shrinkage during high-temperature ironing. If hot cutting is not performed before it has fully shrunk, the hot-cut edge will melt into a single piece, making it difficult to shrink back. The shrinkage rate of hot-cut edges and non-hot-cut edges after heating is different, causing the hot-cut edge to form a wavy shape, which is more likely to scratch the skin and reduce the appearance quality of the woven label. Summary of the Invention

[0004] Therefore, it is necessary to provide a cut-edge woven label with soft edges, low heat shrinkage, and low wavy bending, as well as its preparation method and fabric.

[0005] In a first aspect, the present invention provides a method for preparing a woven label with cut edges, comprising the following steps:

[0006] A woven label pre-finished product is obtained by weaving warp and weft yarns using a woven label machine. The woven label pre-finished product includes a non-cutting area and a cutting area surrounding the non-cutting area. The cutting area includes a front layer, a middle layer, and a bottom layer stacked together. The weft yarns of the front layer, the middle layer, and the bottom layer include low-shrinkage polyester weft yarn, high-shrinkage polyester weft yarn, and viscose weft yarn. The viscose weft yarn, the low-shrinkage polyester weft yarn, and the high-shrinkage polyester weft yarn are alternately arranged, and the viscose weft yarn separates the low-shrinkage polyester weft yarn and the high-shrinkage polyester weft yarn. The warp yarn is polyester yarn with a boiling water shrinkage rate of ≤1%. The boiling water shrinkage rate of the low-shrinkage polyester weft yarn is ≤1%, the boiling water shrinkage rate of the high-shrinkage polyester weft yarn is 34%-38%, and the boiling water shrinkage rate of the viscose weft yarn is 3%-8%. The ironing plate temperature of the woven label machine is 135℃-160℃.

[0007] The woven label pre-finished product is cut along the cutting area to obtain a pre-finished woven label with cut edges;

[0008] The pre-finished woven label with cut edges is immersed in a water bath at 50℃-100℃, and then dried and heat-shrinked in sequence.

[0009] The above-mentioned method for preparing woven labels with cut edges uses polyester with a specific shrinkage rate as warp yarns, and low-shrinkage polyester, high-shrinkage polyester, and viscose as weft yarns. Different weft yarns are arranged at specific intervals in the front, middle, and bottom layers of the cutting area of ​​the label. In the cutting area, the high-shrinkage yarn is surrounded by the viscose yarn. After hot cutting, the label is immersed in hot water at 50℃-100℃ and then dried. Because the viscose yarn does not melt during hot cutting, and after cutting and immersion in hot water, the shrinkage rate of the viscose is greater than that of the low-shrinkage polyester. This allows the cut edge cross-section of the label to form a uniform mesh, preventing the weft yarns from melting into a single piece and becoming less prone to hardening after cooling. This improves the softness of the cut edge of the woven label and enhances the weave. The comfort of the label; high-shrinkage polyester will shrink when immersed in a high-temperature water bath because its surrounding non-heat-melting viscose yarn has a higher shrinkage rate than that of low-shrinkage polyester, which can also form a mesh; after the warp yarns of the woven label are stretched on the label weaving machine, and then pass through the label's own ironing plate at 130℃-160℃, which easily forms a pseudo-setting, the pseudo-setting of the warp yarns will loosen during high-temperature ironing, and the warp yarns will shrink to varying degrees. After improvement, the heat-cut edge has a mesh, and the gap of the mesh formed by the cut edge is close to the gap between the weft yarns of the woven label. During high-temperature ironing, the mesh on the heat-cut edge can shrink and become smaller, and the heat-cut edge will no longer wrinkle; thus, it can prevent the woven label from wavy bending, improve the appearance quality and hand comfort of the woven label.

[0010] In some embodiments, the warp density of the woven label is 4200-5600;

[0011] In some embodiments, the boiling water shrinkage rate of the warp yarn is ≤1%; and / or, the high-shrinkage polyester yarn has a shrinkage rate of 35%-36%; and / or, the boiling water shrinkage rate of the viscose weft yarn is 4%-6%.

[0012] In some embodiments, the color fastness of the warp yarn to dry ironing at 180℃*30S is ≥4; and / or, the color fastness of the viscose weft and the low-shrinkage polyester weft yarn to dry ironing at 180℃*30S is ≥4.

[0013] In some embodiments, the warp yarn has a fineness of 30D-150D; and / or, the low-shrinkage polyester weft yarn has a fineness of 30D-150D; and / or, the high-shrinkage polyester yarn has a fineness of 75D-150D; and / or, the viscose weft yarn has a fineness of 75D-150D.

[0014] In some embodiments, the weft yarn in the woven label pre-finished product comprises, by weight, 60 to 90 parts of the low-shrinkage polyester weft yarn, 5 to 10 parts of high-shrinkage polyester and 10 to 30 parts of the viscose weft yarn.

[0015] In some embodiments, the cutting method is ultrasonic cutting.

[0016] In some embodiments, the heat shrink finishing temperature is 125°C-160°C; and / or,

[0017] The heat shrinking pressure is 0.5-1.5 kg / cm². 2 ; and / or,

[0018] The heat shrink finishing time is 15s-30s.

[0019] In some embodiments, the above preparation method further includes the step of cutting and folding the heat-shrink finished pre-finished woven label.

[0020] The second aspect of the present invention provides a cut-edge woven label obtained according to the above preparation method, which does not wrinkle or fade when dried without tension at 150°C for 15 minutes.

[0021] A third aspect of the present invention provides a fabric comprising the above-described slit woven label. Detailed Implementation

[0029] This invention provides a method for preparing edge-cut woven labels, comprising the following steps S10-S30:

[0030] S10. The warp and weft yarns are woven using a label weaving machine to obtain a pre-finished label.

[0031] The woven label pre-finished product includes a non-cutting area and a cutting area surrounding the non-cutting area. The cutting area includes a front layer, a middle layer, and a bottom layer stacked together. The weft yarns of the front layer, middle layer, and bottom layer include low-shrinkage polyester weft yarn, high-shrinkage polyester weft yarn, and viscose weft yarn. The viscose weft yarn, low-shrinkage polyester weft yarn, and high-shrinkage polyester weft yarn are alternately arranged, and the viscose weft yarn separates the low-shrinkage polyester weft yarn and the high-shrinkage polyester weft yarn. The warp yarn is polyester yarn with a boiling water shrinkage rate of ≤1%. The boiling water shrinkage rate of the low-shrinkage polyester weft yarn is ≤1%, and the boiling water shrinkage rate of the high-shrinkage polyester weft yarn is 34%-38%. The boiling water shrinkage rate of the viscose weft yarn is 3%-8%. The ironing plate temperature of the woven label machine is 135℃-160℃.

[0032] S20. Cut the woven label pre-finished product along the cutting area to obtain the trimmed woven label pre-finished product;

[0033] S30. Immerse the pre-finished woven label with the cut edges in a water bath at 50℃-100℃, and then perform drying and heat shrinking treatment in sequence.

[0034] The viscose weft yarn, low-shrinkage polyester weft yarn, and high-shrinkage polyester weft yarn are alternately arranged, and the viscose weft yarn separates the low-shrinkage polyester weft yarn and the high-shrinkage polyester weft yarn. It can be understood that in the cutting area, the high-shrinkage polyester is surrounded by viscose yarn and separated from the low-shrinkage polyester.

[0035] The above-mentioned method for preparing woven labels with cut edges uses polyester with a specific shrinkage rate as warp yarn, and low-shrinkage polyester, high-shrinkage polyester, and viscose as weft yarn. Different weft yarns are arranged at specific intervals in the front, middle, and bottom layers of the cutting area of ​​the label. In the cutting area, the high-shrinkage yarn is surrounded by the viscose yarn. After hot cutting, the label is immersed in hot water at 50℃-100℃ and then dried. Because the viscose yarn does not melt during hot cutting, and after cutting and immersion in hot water, the shrinkage rate of the high-shrinkage polyester and viscose is greater than that of the low-shrinkage polyester. This allows the cut edge section of the label to form a uniform mesh, preventing the weft yarns from melting into a single piece and becoming less prone to hardening after cooling. This improves the softness of the cut edge of the woven label. This improves the comfort of woven labels. High-shrinkage polyester shrinks during high-temperature water bath immersion because its surrounding non-heat-melting viscose yarn has a higher shrinkage rate due to heat treatment than low-shrinkage polyester, which can also form mesh. After the warp yarns of the woven label are stretched on the label weaving machine, they undergo a pseudo-setting process at 130℃-160℃ using the label's built-in heat press. During high-temperature heat treatment, this pseudo-setting loosens, causing the warp yarns to shrink to varying degrees. The improved heat-cut edge has mesh, and the gaps between the mesh are close to the gaps between the weft yarns of the woven label. During high-temperature heat treatment, the mesh on the heat-cut edge shrinks and becomes smaller, preventing wrinkles. This, in turn, prevents wavy bending of the woven label, improving its appearance quality and hand comfort.

[0036] The aforementioned warp yarn has a boiling water shrinkage rate of less than or equal to 1%. It can be understood that the boiling water shrinkage rate of the warp yarn can be 0%, 0.5%, or 1%. Further, the boiling water shrinkage rate of the warp yarn can be a range of values ​​formed by any two of the aforementioned points. Preferably, the boiling water shrinkage rate of the warp yarn is less than or equal to 0.5%.

[0037] The boiling water shrinkage rate of the aforementioned low-shrinkage polyester weft yarn is less than or equal to 1%. It can be understood that the boiling water shrinkage rate of the low-shrinkage polyester weft yarn can be 0%, 0.2%, 0.5%, 0.8%, and 1%. Furthermore, the boiling water shrinkage rate of the low-shrinkage polyester weft yarn can be a range of values ​​formed by any two of the above points.

[0038] The boiling water shrinkage rate of the aforementioned high-shrinkage polyester weft yarn is 34%-38%. It can be understood that the boiling water shrinkage rate of the high-shrinkage polyester weft yarn can be 34%, 35%, 36%, 37%, or 38%. Further, the boiling water shrinkage rate of the high-shrinkage polyester weft yarn can be a range formed by any two of the above values. Preferably, the boiling water shrinkage rate of the viscose weft yarn is 35%-36%.

[0039] The boiling water shrinkage rate of the viscose weft yarn is 3%-8%. It can be understood that the boiling water shrinkage rate of the viscose weft yarn can be 3%, 4%, 5%, 6%, 7% and 8%. Preferably, the boiling water shrinkage rate of the viscose weft yarn is 4%-6%.

[0040] The ironing plate temperature of the aforementioned woven label machine is 135℃-160℃. It can be understood that the ironing plate temperature of the woven label machine can be 135℃, 140℃, 145℃, 150℃, 155℃, and 160℃. Further, the ironing plate temperature of the woven label machine can be a range formed by any two of the above values. Preferably, the ironing plate temperature of the woven label machine is 145℃-155℃. By adjusting the ironing plate temperature of the woven label machine, the shrinkage rate of each yarn in the weft and warp yarns during the weaving process can be controlled, thereby improving the shrinkage stability of the pre-finished woven label.

[0041] In some embodiments, the warp density of the woven label pre-finished product is 4200-5600. It is understood that the warp density of the woven label pre-finished product can be 4200, 4500, 4600, 4800, 5000, 5200, 5300, 5500, and 5600. Further, the warp density of the woven label pre-finished product can be a range of values ​​formed by any two of the above-mentioned values. Preferably, the warp density of the woven label pre-finished product is 4800-5400. Controlling the density of the woven label pre-finished product can further control the overall shrinkage rate of the woven label pre-finished product. Setting the warp density of the woven label pre-finished product to 4200-5600 can make the woven label pre-finished product less prone to deformation, and can also further prevent deformation of the woven label pre-finished product during the heat shrinkage process.

[0042] In some embodiments, the 180°C*30S dry ironing color fastness of the warp yarn is greater than or equal to 4.0. Controlling the 180°C*30S dry ironing color fastness of the warp yarn can further improve the wash color fastness, water stain color fastness, heat pressing color fastness, acetone color fastness, and bleeding color fastness of the woven label.

[0043] In some embodiments, the 180℃*30S dry ironing color fastness of high-shrinkage polyester weft yarn, viscose weft yarn, and low-shrinkage polyester weft yarn is greater than or equal to 4.0. Controlling the 180℃*30S dry ironing color fastness of the weft yarn can further improve the wash color fastness, water stain color fastness, heat pressing color fastness, acetone color fastness, and bleeding color fastness of the woven label.

[0044] In some embodiments, the fineness of the warp yarn is 30D-150D.

[0045] In some embodiments, the fineness of the aforementioned low-shrinkage polyester weft yarn is 30D-150D.

[0046] In some embodiments, the fineness of the high-shrinkage polyester weft yarn is 75D-150D.

[0047] In some embodiments, the fineness of the viscose weft yarn is 75D-150D.

[0048] In some embodiments, the weft yarn comprises, by weight, 60 to 90 parts of low-shrinkage polyester weft yarn, 5 to 10 parts of high-shrinkage polyester and 10 to 30 parts of viscose weft yarn.

[0049] In some embodiments, the above-described cutting process may employ thermal cutting.

[0050] In some embodiments, the above-described cutting method employs ultrasonic cutting.

[0051] In some embodiments, the cutting speed of ultrasonic cutting is 12-20 m / min. Controlling the cutting speed of ultrasonic cutting helps to prevent the cutting from shifting.

[0052] In some embodiments, the blade thickness for ultrasonic cutting is 0.3mm-0.45mm. Controlling the blade thickness during cutting helps prevent fraying after cutting.

[0053] The phrase "immersing the pre-finished woven label with cut edges in a water bath at 50℃-100℃" can refer to 50℃, 60℃, 70℃, 80℃, 90℃, and 100℃. Further, the water bath temperature can be any range formed by any two of the above values. Preferably, the water bath temperature is 80℃-100℃.

[0054] In some embodiments, the pre-finished cut-edge woven label is immersed in a water bath at 50°C-100°C for 20-45 seconds.

[0055] In some embodiments, the drying temperature is 100℃-160℃. It is understood that the drying temperature can be 100℃, 110℃, 120℃, 130℃, 140℃, 150℃, and 160℃. Further, the drying temperature can be a range formed by any two of the above values. Preferably, the drying temperature is 140℃-155℃.

[0056] In some embodiments, the heat shrink finishing temperature is 125°C-160°C.

[0057] In some embodiments, the tension of the heat shrink finishing is 0N, which can be understood as the heat shrink finishing being carried out under tension-free conditions.

[0058] In some embodiments, the heat shrinking pressure is 0.5-1.5 kg / cm². 2 Controlling the pressure during heat shrinking finishing is beneficial for label shrinkage and surface smoothing.

[0059] In some embodiments, the heat shrink finishing time is 15s-30s.

[0060] In some embodiments, prior to the drying process, the impregnated, trimmed woven label pre-finished product is passed through a pressure roller for rolling.

[0061] In some embodiments, the over-pressure roller has a roll allowance of 90%-110%.

[0062] In some embodiments, the heat-shrink finishing step is followed by cutting and folding the heat-shrink finished pre-made woven label.

[0063] In one embodiment, a cut-edge woven label prepared according to the above method is provided, which does not wrinkle or fade when dried without tension at 150°C for 15 minutes.

[0064] In one embodiment, the ratio of A / B is (1.1-1.25); where 6000 is an empirical constant regarding the warp density of the woven label, obtained by the inventors through multiple derivations and verifications; A is the ratio of the area of ​​the mesh yarn that can be formed on the cut edge of the woven label to the sum of the areas of all yarns on the cut surface, that is, the ratio of the mesh area to the total area of ​​the cut surface; B is the porosity left by the warp arrangement of the weft yarns, expressed as the ratio of (6000 - warp density of the woven label) / 6000; more Specifically, A = (high shrinkage polyester fraction * high shrinkage polyester fineness D number + viscose yarn fraction * viscose yarn / filament fineness D number) / (high shrinkage polyester fraction * high shrinkage polyester fineness D number + viscose yarn fraction * viscose yarn / filament fineness D number + low shrinkage polyester fraction * low shrinkage polyester fineness D number), B = (6000 - high shrinkage polyester density * high shrinkage polyester fineness D number + viscose yarn / filament density / * viscose yarn / filament fineness D number + low shrinkage polyester density * low shrinkage polyester fineness D number / 6000).

[0065] During the high-temperature washing, dyeing, drying, and ironing of woven labels along with garments, gaps exist between the weft yarns in the non-heat-cut areas. These gaps shrink under high temperatures. During this shrinkage process, the mesh openings of the woven label shrink from round holes to oval holes, preventing the heat-cut edges from bending upwards or downwards. Further controlling the ratio of the mesh opening area to the weft yarn gap area of ​​the woven label to (1.1-1.25) can further ensure that it can withstand higher ironing temperatures.

[0066] In one embodiment, the warp density of the cut-edge woven label is 6000.

[0067] In one embodiment, a fabric is provided that includes the aforementioned cut-edge woven label.

[0068] In some embodiments, the fabrics include, but are not limited to, garments, scarves, hats, trousers, gloves, and shoes.

[0069] To make the objectives, technical solutions, and advantages of this invention clearer and more concise, the invention is described using the following specific embodiments, but the invention is by no means limited to these embodiments. The embodiments described below are merely preferred embodiments of the invention and can be used to describe the invention, but should not be construed as limiting the scope of the invention.

[0143] Performance testing methods and evaluation indicators:

[0144] 1. Heat shrinkage rate: 150℃*15S, check the change in the size of the marking after heat treatment. Mark size calculation: Result = A (before heat treatment) - B (after heat treatment), less than 1.0% is acceptable.

[0145] 2. Heat shrinkage rate: Sew the woven label to be tested onto the fabric (sew around all four sides and at both ends), dry at 150℃ for 15 minutes, and observe the change in the marked size after drying. Shrinkage rate = (A (before drying) - B (after drying)) / A (before drying), less than 2.5% is acceptable.

[0146] 3. Evaluation of wrinkling and arching effect: Sew the label to be tested and the ordinary label onto the knitted garment fabric (sew at both ends), wash at 80℃-100℃ for 30 minutes, hang dry at 150℃ for 15 minutes without tension, and give an evaluation, evaluating the wrinkling and arching effect.

[0147] 4. Colorfastness to washing: according to the method specified in AATCC 61-2013.

[0148] 5. Water fastness: according to the method specified in AATCC 107-2019.

[0149] 6. Colorfastness to Pressing: Following the method specified in AATCC 133-2020, wet pressing at 150℃ for 15 seconds, color fastness to white fabric is assessed using the AATCC staining card.

[0150] 7. Acetone color fastness: Test sample 1g, cut the sample into pieces smaller than 1CM, immerse it completely in 10ML of acetone solution for 1 minute, take out the sample, observe the color of the sample solution, and use AATCC staining to evaluate the color level.

[0151] 8. Colorfastness to bleeding: After dry pressing the sample at 110℃ and 150℃, immerse it in a nonionic surfactant solution for 2 hours, remove it and air dry it at room temperature, and check the degree of color transfer to determine the colorfastness. Use the AATCC staining card to assess the staining of white cloth.

[0152] 9. Evaluation method for the appearance of woven labels after washing and drying: Sew the finished woven label onto the fabric, then wash at 50℃-60℃ for 30 minutes and dry at 150℃ for 15 minutes without tension. Compare the wrinkles with the original appearance.

[0153] The performance test data for each embodiment and comparative example are shown in Table 1:

[0154] Table 1

[0155]

[0156] Continued table

[0157]

[0158] As can be seen from the performance test data in Table 1, the viscose weft yarn used in Comparative Example 1 has a boiling water shrinkage rate of 2.0%. The woven label prepared with this yarn wrinkled after being sewn onto the garment and then washed and hung to dry at high temperature. In Comparative Example 2, when the viscose weft yarn was replaced with black polyester with the same boiling water shrinkage rate, the woven label had no mesh gaps, and the garment wrinkled significantly after hanging to dry. In Comparative Example 3, white polyester yarn with a low shrinkage rate was used instead of the high shrinkage polyester yarn in Example 1. The resulting woven label had small mesh holes, and after being sewn onto the garment and then washed and hung to dry, the garment wrinkled. Comparative Examples 4 and 5 omitted the mesh forming and heat shrinking steps, respectively, resulting in woven labels with poor mesh effect, very small mesh holes, and wrinkling at the edges during heat drying. In Comparative Example 6, the pre-finished cut-edge woven label was immersed in water at 40°C, resulting in a poor mesh formation effect. However, Example 1, employing the technical solution of this invention, produced a cut-edge woven label with soft edges, good comfort, and no wavy bending. Its heat shrinkage rate reached 1.6%. After being sewn onto a knitted garment and washed and hung to dry, the garment remained wrinkle-free. Therefore, this application, through the above technical solution, produces a cut-edge woven label with soft edges, low heat shrinkage rate, and minimal wavy bending.

[0159] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
