Description

Technical Field

[0001] The present application relates to the field of textile technology, and in particular to a woven label and a preparation method thereof. Background Art

[0002] In the textile industry, polyester woven labels serve as identification tags, conveying brand names, logos, and product information, as well as product size, origin, ingredients, and descriptions. They are widely used on clothing, shoes, hats, luggage, home textiles, and handicrafts. Before leaving the factory, woven labels are sewn onto other fabrics, with cotton being the most common. Cotton fiber is a natural fiber with good moisture absorption, a moisture content of 8% to 10%, and excellent moisture retention and warmth retention. Cotton fiber is non-irritating to the skin, soft yet not stiff, and beneficial to the human body, making it widely used in clothing and home textiles.

[0003] To achieve dimensional stability, a soft touch, and unique color and texture effects, textile mills wash cotton textiles before shipping. Conventional polyester labels shrink less than cotton textiles in washing, resulting in a significantly different shrinkage rate for the polyester label attached to the cotton textile. In particular, when the polyester label is sewn along its perimeter, it can become noticeably uneven, wavy, or wrinkled after washing, impacting the garment's appearance and comfort. Traditionally, one approach to addressing this issue is to sew the edges of the polyester label onto the cotton textile. However, this can affect consumer comfort after washing. Another approach involves washing the textile first and then applying the polyester label. However, this exposed seams can affect the overall aesthetics of the product. Summary of the Invention

[0004] Based on this, it is necessary to provide a woven label and a preparation method thereof to address the above problems, so that the shrinkage rate of the polyester woven label is the same as that of the target fabric.

[0023] In one embodiment, the washing shrinkage of the woven label is 2% to 5%.

[0024] The woven label prepared by the preparation method of the present application improves the washing shrinkage rate of the polyester woven label. When the polyester woven label is sewn on the target fabric, the difference in washing shrinkage between the polyester woven label and the target fabric will not affect the user's wearing experience, so that the polyester woven label is more compatible with the target fabric and avoids problems such as overall unevenness, waving or wrinkling of the fabric product.

[0029] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0030] In the description of this application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0031] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, if the term "plurality" appears, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0032] Research has found that the washing shrinkage of conventionally produced polyester labels is lower than that of cotton textiles. This results in polyester labels affixed to cotton textiles exhibiting significantly different shrinkage rates than cotton textiles. In particular, when polyester labels are sewn along the perimeter of the cotton textile, they can become noticeably uneven, wavy, or wrinkled after washing, impacting the garment's appearance and comfort. Related techniques include sewing polyester labels on both sides of the cotton textile, or washing the textile first before sewing the polyester label. The former approach, because the polyester label is sewn only on two sides, affects consumer comfort after washing. The latter approach, because exposed seams affect the appearance and overall aesthetics of the product. Woven labels on the market, whether they are cut edge labels or selvedge labels, do not have a high shrinkage rate. Especially when sewn along the four sides on cotton textiles, cotton textiles have a higher shrinkage rate, while polyester woven labels have a lower shrinkage rate. Due to the inconsistent shrinkage rates of the two, problems such as unevenness, wavy or wrinkled will occur.

[0033] Based on the above, the present application provides a polyester woven label with a high washing shrinkage rate. The woven label is woven from warp yarns and weft yarns according to a preset pattern. The warp yarns are made of FDY polyester material, and the weft yarns are made of DTY polyester material. The washing shrinkage rate of the woven label is 1%-8%, which needs to match the washing shrinkage rate of the target fabric to be sewn. The polyester woven label woven with FDY polyester material and DTY polyester material can increase the washing shrinkage rate to the above range. Therefore, when the polyester woven label is sewn on common fabrics, the shrinkage difference between the polyester woven label and the target fabric will not affect the user's wearing experience, making the polyester woven label more compatible with the target fabric. At the same time, the woven label with a high washing shrinkage rate is suitable for a variety of sewing methods, has a wide applicability, and is easy to select the sewing process.

[0034] Fabric shrinkage refers to the reduction in size or dimensions of a fabric or garment after being heated or washed. Shrinkage may occur in both the longitudinal (warp) and transverse (weft) directions. Washing shrinkage is the extent to which a fabric shrinks after coming into contact with water, and depends on the fiber content, weaving, finishing, and conditions of the fabric. Methods for testing fabric shrinkage include, but are not limited to, dry steaming, boiling water, and washing. Generally, the shrinkage of the fabric in both the warp and weft directions must be measured. The washing shrinkage in this application refers to one of the washing shrinkage in the warp, weft, and total area directions.

[0035] The shrinkage rate test can be measured in accordance with the relevant national standards. Taking the washing type as an example, the washing shrinkage rate test process and method are as follows: (1) Sampling: Take samples from the same batch of fabrics, at least 5 meters away from the end of the cloth. The cloth sample should not have defects that affect the results. The sample is cut into a square with a width suitable for washing, with a specification of 70-80 cm. After lying naturally for several hours, place a 50 cm * 50 cm sample in the middle of the cloth, and then use a box pen to draw lines on the edges; (2) Marking: Place the sample on a flat surface, smooth out creases and irregularities, do not stretch it, and do not use force when drawing lines to avoid displacement; (3) Washing the sample: To prevent the marked area from fading after washing, it must be sewn (knitted fabrics are double-layered, woven fabrics are single-layered). When sewing, knitted fabrics are only sewn on both sides of the warp direction and one side of the weft direction. Woven fabrics must be sewn on all four sides with appropriate tightness. Coarse fabrics or fabrics that are easy to spread must be hemmed with three lines on all four sides. After the sample is made, put it in warm water at 20-40 degrees, wash it with a washing machine, dry it with a dryer or let it dry naturally. After it has cooled down sufficiently, take the actual measurement; (4) Calculation: Shrinkage rate = (size before washing - size after washing) / size before washing × 100%.

[0036] The washing shrinkage of conventional polyester woven labels is less than 2% or even less than 1%. In order to match the shrinkage of the target fabric to be sewn, the washing shrinkage of the polyester woven label is 1%-8%. Furthermore, the washing shrinkage of the polyester woven label is 1%-8%.

[0037] In one embodiment, when the target fabric is cotton, the washing shrinkage rate of the target fabric is 2%-5%, and the washing shrinkage rate of the woven label is 2% to 5%; when the target fabric is cellulose fiber, the washing shrinkage rate of the target fabric is 4% to 8%, and the washing shrinkage rate of the woven label is 4% to 8%.

[0038] In one embodiment, the difference between the washing shrinkage of the polyester woven label and the target fabric is less than or equal to 20%. Preferably, the difference between the washing shrinkage of the polyester woven label and the target fabric is less than or equal to 10%. When the difference between the washing shrinkage of the polyester woven label and the target fabric is within the above range, the shrinkage difference between the polyester woven label and the target fabric will not affect the user's wearing experience, and the sewing process is also conveniently selected, ensuring that the polyester woven label is more compatible with the target fabric.

[0039] It is understood that the washing shrinkage of the woven label and the target fabric are measured using the same standard test method to ensure that the woven label and the target fabric have the same washing shrinkage.

[0040] Fully drawn yarn (FDY) is a synthetic filament produced by spinning and drawing. The fiber is fully stretched and can be directly used in textile processing. DTY low-stretch polyester yarn is made from polyester low-stretch yarn. DTY is a type of textured polyester chemical fiber. It is made from polyester chips (PET) by high-speed spinning of polyester pre-oriented yarn (POY), which is then subjected to a drawing and false twist texturing process.

[0041] In one embodiment, the warp yarn is produced by Z-twisting or S-twisting. Furthermore, the FDY polyester warp yarn is produced by Z-twisting or S-twisting at 300 to 650 turns per meter. When the twist of FDY polyester warp yarn is less than 300 turns per meter, yarn breakage and fuzzing are likely to occur during weaving, affecting machine efficiency and the appearance of the woven label. When the twist of FDY polyester yarn is greater than 650 turns per meter, the yarn feels too stiff and is prone to curling, which is not conducive to warping and weaving.

[0042] In one embodiment, the weft yarn is produced by one of Z-twisting, S-twisting, meshing, and false twisting. Furthermore, the weft yarn is produced from DTY polyester mesh yarn using Z-twisting of 100 to 300 turns / meter or S-twisting of 100 to 300 turns / meter, or by weaving the DTY polyester mesh yarn through a heavy mesh, medium mesh, or light mesh, or by false twisting. DTY polyester mesh yarns lack twist or meshing, and are prone to breakage during weaving, resulting in weaving defects. DTY polyester mesh yarns with a twist exceeding 300 turns / meter or excessive meshing can affect the feel of the woven label and the yarn's gloss.

[0043] In one embodiment, warp and weft yarns are woven on a loom that captures weaving parameters and converts them into a weaving plan, thereby weaving the warp and weft yarns input into a predetermined pattern. The weaving parameters include at least one of the warp and weft yarn color, thickness, arrangement sequence, interweaving pattern, interweaving density, and a marking for subsequent processing of the woven label. The automated operation of the loom can improve the production efficiency of woven labels.

[0044] Specifically, the loom converts the signals by inputting weaving parameters to form a preset pattern for display. At the same time, the weaving parameters are converted into motion parameters of the corresponding components of the loom, and the components weave the warp and weft yarns into woven labels through movement.

[0045] like Figure 1 As shown, Figure 1 The method for preparing a polyester woven label with high washing shrinkage according to an embodiment of the present application is shown, comprising the steps of:

[0046] S100, processes FDY polyester warp yarn and winds the warp yarn onto the warp beam;

[0047] S200, processing DTY polyester weft yarn;

[0048] S300, weaving warp yarns and weft yarns into a woven label according to a preset pattern; wherein the tension of the warp yarn is greater than the tension of the weft yarn, a heat setting process is used during weaving, and the washing shrinkage rate of the woven label is 1% to 8%;

[0049] S400: cutting the woven label multiple times to form multiple woven label strips.

[0050] In one embodiment, step S100 further includes the following steps:

[0051] S110, Z-twisted warp yarn, or S-twisted warp yarn.

[0052] S120, winding warp yarns of a preset number and length in parallel on a warp beam of a preset width in a manner that meets arrangement requirements.

[0053] In one embodiment, step S200 further includes the following steps:

[0054] S210, Z-twisted weft yarn, S-twisted weft yarn, meshed weft yarn or false twisted weft yarn. The weft yarns include multiple groups made by various twisting methods.

[0055] In one embodiment, step S300 further includes the following steps:

[0056] S310: Setting weaving parameters.

[0057] Specifically, weaving parameters include the color, thickness, arrangement sequence, interweaving pattern, and density of the warp and weft yarns, as well as at least one of the following: markings used for subsequent processing of the woven label. The loom receives these weaving parameters and converts them into signals to form a preset pattern for display. Simultaneously, these weaving parameters are converted into motion parameters for the corresponding loom components, which then move to weave the warp and weft yarns into the woven label. The automated operation of the loom can improve the production efficiency of woven labels.

[0058] S320. Weave the input warp and weft yarns into a preset pattern according to preset conditions. The preset conditions include, but are not limited to, warp tension, weft tension, or processing temperature; the warp tension is greater than the weft tension; a heat setting process is used during weaving; and the washing shrinkage of the woven label is 1% to 8%.

[0059] In one embodiment, the preset conditions include: a warp tension of 20 to 65 g, a weft tension of 5 to 30 g, and a heat setting process temperature of 70° C. to 110° C. Preferably, the warp tension is 30 to 65 g, the weft tension is 5 to 20 g, and the heat setting process temperature is 80° C. to 105° C.

[0060] When the warp tension is less than 30g, especially less than 20g during weaving, the loom opening is small, and the weft feeding device of the loom is prone to hit the warp yarn and stop the loom; when the warp tension is greater than 60g, especially greater than 65g, the warp yarn is easy to break during the weaving process, and the accumulated time will cause the loom roller to deform, affecting the life of the loom; the above-mentioned warp tension makes the loom opening clear and easy to weave, has little effect on the loom roller, and can reserve internal stress along the warp direction of the woven label after heat setting.

[0061] A weft tension of less than 5g during weaving is not conducive to weft insertion and picking; when the weft tension is greater than 20g, especially greater than 30g, the weft will shrink when it is cut, causing the woven label near the edge of the fabric to become skewed and form a defective product; a weft tension of 5 to 20g is convenient for weft insertion and picking, and will not cause the woven label to deform due to yarn shrinkage caused by weft cutting.

[0062] When the heat setting temperature of the woven label machine is less than 80°C, especially less than 70°C during weaving, it cannot set the interwoven woven label, but instead causes the interwoven woven label to be distorted, deformed and uneven; when the heat setting temperature of the woven label machine is greater than 105°C, especially greater than 110°C, the washing shrinkage rate of the woven label after it is set but sewn onto the textile and washed cannot meet the requirements; a woven label machine setting temperature of 80°C to 105°C can not only keep the woven label smooth in appearance without affecting production and processing and sewing on textiles, but also can make the shrinkage rate of the polyester woven label sewn around the four sides on the cotton textile after washing reach between 1% and 8%, and in particular, can achieve a woven label washing shrinkage rate of 2% to 5%, so that the washing shrinkage rate of the polyester woven label is consistent with that of the cotton textile, has a smooth appearance, and does not affect the wearing comfort.

[0063] In one embodiment, step S400 includes at least one of the following steps:

[0064] S410, cutting the woven label into a plurality of first woven label strips with a width of at least 8 mm.

[0065] S420, cutting the woven label into a plurality of second woven label strips using an ultrasonic knife;

[0066] S430, cutting the woven label into a plurality of third woven label strips using a cutter at a temperature of 300-500°C.

[0067] In one embodiment, the above steps S410, S420 or S430 may be performed in sequence, that is, the step with the earlier sequence number is executed first.

[0068] Specifically, in step S410, the woven label is cut into a plurality of first woven label strips on a loom, or the loom is used to weave a plurality of first woven label strips having a width of at least 6 mm to 80 mm. Preferably, the woven label is cut into a plurality of first woven label strips having a width of at least 100 mm, 150 mm, 200 mm, or 250 mm. The woven label can be cut into a plurality of first woven label strips having a width of at least 100-250 mm.

[0069] Specifically, in step S420, the woven label or the plurality of first woven label strips are slit into a plurality of second woven label strips on an ultrasonic slitting machine using an ultrasonic blade with a thickness of 0.2 to 0.5 mm at a speed of 0.5 to 2 m / min.

[0070] Specifically, step S430 uses a shear folding machine to cut, with a cutter temperature of 380° C. to 420° C. and a frequency of 100 to 150 times per minute to process the woven label, the multiple first woven labels or the multiple second woven labels into the multiple third woven labels.

[0106] Comparative Example 1

[0107] Comparative Example 1 is basically the same as Example 1, except that: in Comparative Example 1, the warp yarn in Example 1 is replaced by DTY polyester material instead of FDY polyester material. The polyester woven label produced in Comparative Example 1 by processing according to the same parameters and steps as Example 1 has a washing shrinkage rate of 5%, but random warp streaks are found on the surface of the woven label after washing, affecting the appearance of the polyester woven label and the textile.

[0108] Comparative Example 2

[0109] Comparative Example 2 is basically the same as Example 1, except that: in Comparative Example 1, the weft yarn in Example 1 is replaced by FDY polyester material instead of DTY polyester material. The polyester woven label produced in Comparative Example 2 by processing according to the same parameters and steps as Example 1 has a washing shrinkage rate of 5%. However, after washing, random weft streaks appear on the surface of the woven label and the hand feels hard, affecting the appearance of the polyester woven label and the textile as well as the wearing comfort of consumers.

Figure 3 The upper and lower edges of the woven label are not straight but wavy, which does not meet the requirements.

[0114] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described.
