Description

Technical Field

[0001] The present invention relates to the technical field of textile clothing, and specifically to a warp knitted fabric with quick drying, cold feeling and stiffness.

Background Art

[0002] The weaving process includes weaving (also called shuttle weaving), knitting, braiding and non-woven fabrics. Among them, knitting can also be divided into warp knitting and weft knitting. Warp knitting is one of the spinning processes belonging to the field of knitting. One set or several sets of parallel yarns are vertically supplied to all the working needles of the machine and at the same time loops are formed to make a knitted fabric. This method is called warp knitting, and the formed knitted fabric is called a warp knitted fabric.

[0003] The warp knitted fabrics in the prior art have the following problems: (1) General warp knitted fabrics have general hygroscopicity. When worn on the body, it is difficult to quickly absorb and dry sweat, and the drying speed is relatively slow, making it difficult to meet people's needs. (2) The stiffness of the fabric is relatively low and cannot meet the needs of users. (3) The elasticity of the fabric is low, which is very uncomfortable for users.

[0004] The present application is made in view of these.

Summary of the Invention

[0005] In view of these, the present invention is to provide a warp knitted fabric with quick drying, cold feeling and stiffness, thereby solving the problem that the fabrics in the prior art cannot simultaneously have quick drying, cold feeling, stiffness and elasticity.

[0006] To achieve the above object, the technical solution of the present invention is realized as follows.

[0007] The warp-knitted fabric is quick-drying, cool, and firm, and is knitted with at least two hacklings, GB1 and GB2. The yarn used for GB1 hackling is a highly mechanically elastic synthetic fiber filament with a round or irregular cross-section, and the yarn used for GB2 hackling is an elastic polyurethane filament. The thickness of the highly mechanically elastic synthetic fiber filament is 20 to 50D, and the thickness of the elastic polyurethane filament is 55D or less.

[0008] Preferably, when the cross-section of the high mechanical elasticity synthetic fiber filament is an irregular cross-section, this structure gives the fiber filament a relatively large specific surface area, a large contact area between the fiber and air, which is advantageous for the diffusion and evaporation of moisture on the fiber surface, allowing the wearer to experience a quick-drying and cooling sensation after wearing the fabric. At the same time, the high curl rate of the high mechanical elasticity synthetic fiber filament gives the fabric a relatively high degree of firmness, and the fabric obtained by knitting with the high mechanical elasticity synthetic fiber filament and elastic spandex filament has excellent elasticity, improving the wearer's comfort.

[0009] Furthermore, the fineness of the above-mentioned highly mechanically elastic synthetic fiber filaments ranges from 12 to 48 F. The reason for limiting the number of monofilaments in yarn selection is as follows:

[0010] 1. The number of monofilaments (unit F) can greatly influence the quick-drying, cool-to-the-touch, and crisp-feeling properties of a fabric. For the same fineness, a higher number of monofilaments and a higher F number mean a greater number of spun yarns in the yarn. On the one hand, the larger contact area between the fibers and air increases the moisture permeability and quick-drying properties of the fabric, which is advantageous for the evaporation and diffusion of moisture on the yarn surface. At the same time, the fabric can dissipate heat better, improving the quick-drying and cool-to-the-touch properties of the fabric. On the other hand, the fabric feels softer to the touch, and the yarn structure is more compact, resulting in a crisp-feeling fabric that is not stiff, flat, and resistant to deformation.

[0011] 2. However, the more monofilaments there are, the lower the hook resistance and durability of the fabric, and the easier it is for the monofilaments to diverge. This reduces the weaving performance of the yarn in warp knitting, making it easier for yarn to be generated during warping. Warped yarn increases the probability of breakage during weaving, and if monofilaments diverge easily during weaving, some monofilaments may not be able to be supplied to the needle hook, resulting in breakage.

[0012] Furthermore, the curl shrinkage rate of the above-mentioned highly mechanically elastic synthetic fiber filament must be greater than 25%, and preferably, the curl shrinkage rate of the above-mentioned highly mechanically elastic synthetic fiber filament is 25-45%. The significance of limiting the curl shrinkage rate in the selection of the highly mechanically elastic synthetic fiber filament is as follows.

[0013] The curl shrinkage rate can have a significant impact on the quick-drying, cool-to-the-touch, and crisp performance of a fabric. The greater the curl shrinkage rate, the following advantages are observed: 1) The gaps between fibers increase, which is advantageous for the diffusion and evaporation of moisture within the fabric, improving its quick-drying properties; 2) More air layers are formed on the fabric surface, increasing the contact area between the fabric and air, which is advantageous for improving the fabric's heat dissipation performance; and 3) The fibers can quickly return to their original shape when subjected to external forces, which helps maintain the fabric's crispness.

[0014] Furthermore, the threading rate for the GB1 hackling and GB2 hackling must reach 95% or higher. The threading method for the GB1 hackling is full threading, while the threading method for the GB2 hackling is not full threading. The threads for the GB1 hackling and GB2 hackling can be supplied in the same direction or in opposite directions.

[0015] Furthermore, the interval between GB1 hackling movements must be less than or equal to the distance between three knitting needles, and the knitting form may be open or closed. The interval between GB2 hackling movements must be less than or equal to the distance between two needles, and the knitting form may be open or closed.

[0016] In this installation, it is required that the curl shrinkage rate of the yarn used for GB1 hackling be slightly larger. By combining the movement method of GB1 and GB2 hackling with the direction of yarn supply, the fabric can maintain gaps between the yarns, further improve the breathability of the fabric, and achieve excellent stiffness and quick-drying / cooling performance. In particular, in the process where the upper density of the high mechanical elastic synthetic fiber filament is 26 to 35 rows / inch, an excellent stiffness effect can be achieved.

[0017] Furthermore, the above-mentioned highly mechanically elastic synthetic fiber filament is 40D / 12F full-dull nylon 6 or 40D / 12F full-dull nylon 66, and the GB1 hackling is threaded entirely through 40D / 12F full-dull nylon 6 or 40D / 12F full-dull nylon 66, while the above-mentioned elastic polyurethane filament is spandex yarn, and the GB2 hackling is threaded through spandex yarn.

[0018] Furthermore, the irregular cross-section of the above-mentioned highly mechanically elastic synthetic fiber filament includes one of the following: a cross shape, a Y shape, or a pentagon.

[0019] Furthermore, the warp-knitted fabric includes anti-roll-up structures located on both sides of the fabric width, with the width of the anti-roll-up structure on either side of the fabric width being 1.8 to 2 cm, and the fabric width correspondingly being 1.5 m to 1.8 m.

[0020] Furthermore, the specific threading method for the above-mentioned anti-winding structure involves using 4 to 5 needles on both sides of the fabric width to thread the entire length, passing the needle through once without threading, repeating this 10 to 12 times, and accumulating a total width of 1.8 to 2 cm.

[0021] This installation prevents the fabric from curling up, improves the fabric's smoothness, firmness, and quick-drying / cooling properties, thereby avoiding streaks, uneven dyeing, and wrinkles during dyeing, significantly reducing production costs, and lowering the probability of defective products.

[0022] Furthermore, the high mechanical elasticity synthetic fiber filaments are composed of 40D / 12F semi-dull nylon 6 and 40D / 12F full-dull nylon 6. The GB1 hackling passes through 40D / 12F semi-dull nylon 6 and 40D / 12F full-dull nylon 6. The elastic polyurethane filament is spandex yarn, and the GB2 hackling passes through spandex yarn. Among them, the arrangement pattern of semi-dull nylon 6 and full-dull nylon 6 is an alternating arrangement of 1:2.

[0023] In this installation, the selection of the yarn thickness and fineness of nylon 6, as well as the alternating installation, can improve the gaps in the fabric, improve the air permeability of the fabric, and further improve the quick-drying property of the fabric. Also, due to the installation of semi-dull nylon and full-dull nylon, one side of the fabric has a fine texture and the other side is smooth, giving the fabric excellent suction.

[0024] Furthermore, the machine type used for the warp knitting of the above fabric is one of tricot HKS-2SE and HKS-2SEPLUS.

[0025] Furthermore, the needle distance used for the knitting of the above fabric is 36 - 40G.

[0026] Furthermore, the weight percentage of the high mechanical elasticity synthetic fiber filaments in the whole fabric is 70 - 80%, and the weight percentage of the elastic polyurethane filaments in the whole fabric is 20 - 30%.

[0027] Furthermore, the warp and weft density product of the above warp knitting fabric reaches 1100 meshes / square centimeter or more.

[0028] Furthermore, the warp and weft density product of the above warp knitting fabric reaches 1500 - 2000 meshes / square centimeter.

[0029] Furthermore, the longitudinal density of the above warp knitting fabric is 40 - 60 threads / cm, and the transverse density is 27 - 33 threads / cm.

[0030] In this setting, due to the warp and weft density product, the yarn arrangement is appropriately densified, the structure is stable, the fabric has an excellent stiffness, and furthermore, sweat is quickly absorbed and diffused through the fine passages between the yarns, thereby helping to achieve quick drying, while at the same time reducing the air flow and heat exchange and providing a cooling sensation.

[0031] Furthermore, the deniers of the above high mechanical elasticity synthetic fiber filaments and elastic polyurethane filaments are the same.

[0032] Compared with the prior art, the warp knitted fabric with quick drying, cooling sensation and stiffness described in the present invention has the following advantages.

[0033] (1) The present invention uses high mechanical elasticity synthetic fiber filaments with a special cross-section. The fiber filaments have a relatively large specific surface area, a large contact area between the fibers and the air, which is beneficial to the diffusion and evaporation of moisture on the fiber surface. After the wearer wears the fabric, the wearer can have a quick drying and cooling sensation experience. At the same time, due to the high curl rate of the high mechanical elasticity synthetic fiber filaments, the fabric can be given a relatively high stiffness. Moreover, the fabric knitted with the high mechanical elasticity synthetic fiber filaments and elastic spandex filaments has excellent elasticity, which improves the wearing comfort of the user.

[0034] (2) The yarn used for the GB1 hacking in the present invention is a high mechanical elasticity synthetic fiber filament. The curl shrinkage rate of the above high mechanical elasticity synthetic fiber filament must be greater than 25%. By aligning with the same direction as the movement modes of GB1 and GB2, the fabric can maintain the gaps between the yarns, further improve the air permeability of the fabric, and achieve excellent stiffness performance and quick drying and cooling sensation performance. Among them, in the process where the上机 density (I'm not sure what "上机密度" exactly means, it might be a misspelling or a specific term in a particular field, here I keep it as it is) of the high mechanical elasticity synthetic fiber filament is 26 - 35 rows / inch, an excellent stiffness effect can be achieved.

[0035] (2) The anti-winding-up structure in the present invention can prevent the fabric from winding up, improve the smoothness, stiffness, and quick drying and cooling sensation of the fabric, and avoid the occurrence of streaks, dyeing unevenness, and wrinkles during dyeing, greatly reducing the production cost and the probability of defective products. [Brief explanation of the drawing]

[0036] [Figure 1] This is a schematic diagram of the structure of Embodiment 1 of the present invention. [Figure 2] This is a schematic diagram of the structure of Example 2 of the present invention. [Modes for carrying out the invention]

[0037] To make the above-mentioned objectives, features, and advantages of the present invention clearer and easier to understand, specific embodiments of the present invention will be described in detail below with reference to the drawings.

[0038] Example 1 As shown in Figure 1, the present invention provides a quick-drying, cool, and crisp warp-knitted fabric. The fabric is knitted using two hacklings GB1 and GB2 on a warp knitting machine, with a needle distance of 40G. The machine used is a Tricot HKS-2SE. The GB1 hackling is threaded with 40D / 12F full-dull nylon 6 with a cross-shaped cross-section, and the GB1 hackling is threaded with 40D elastic spandex yarn. Of the total weight, the full-dull nylon 6 accounts for 77% of the fabric, and the elastic spandex yarn accounts for 23% of the fabric.

[0039] Specifically, the curl rate of 40D / 12F full-dull nylon 6 is 45%.

[0040] Specifically, the upper loom density for knitting full-dull nylon 6 is 28 rows / inch, and in the structure of the warp-knitted fabric described above, the GB1 hackling and GB2 hackling use a co-direction feeding method, the GB1 hackling span is the distance of one needle, its knitting style is open, the GB1 hackling back yarn cord is 0-1 / 2-1 / / , the GB2 hackling span is the distance of one needle, its knitting style is closed, and the GB2 hackling back yarn cord is 1-0 / 1-2 / / .

[0041] More specifically, the threading method for GB1 hackling is full threading, with a 100% threading rate, while the threading method for GB2 hackling is not full threading, with a 97% threading rate. Specifically, five needles are used on both sides of the fabric width to thread the thread completely, with one empty pass, repeated 10 times, resulting in a cumulative width of 2 cm. The specific threading is AAAAAB, where A represents thread splicing and B represents no thread splicing, and the fabric width corresponds to 1.5 m.

[0042] Specifically, the warp-to-vertical density product of the above warp-knitted fabric reaches 1500 mesh / square centimeter, the longitudinal density of the above warp-knitted fabric is 50 threads / cm, and the transverse density is 30 threads / cm.

[0043] Example 2 As shown in Figure 2, the present invention provides a quick-drying, cool, and crisp warp-knitted fabric. The fabric is knitted using two hacklings GB1 and GB2 on a warp knitting machine, with a needle distance of 36G. The machine used is a Tricot HKS-2SEPLUS. The GB1 hackling passes through 40D / 12F full-dull nylon 6 and 40D / 12F semi-dull nylon 6, both of which have a Y-shaped cross-section. The GB1 hackling also passes through 40D elastic spandex yarn.

[0044] Specifically, the upper loom density for knitting full-dull nylon 6 and semi-dull nylon 6 is 32 rows / inch, and in the structure of the warp-knitted fabric described above, the GB1 hackling and GB2 hackling use a co-direction feeding method, the span of the GB1 hackling is the distance of one needle, its knitting style is closed, the backing thread cord of the GB1 hackling is 1-0 / 1-2 / / , the span of the GB2 hackling is the distance of one needle, its knitting style is closed, and the backing thread cord of the GB2 hackling is 1-0 / 1-2 / / .

[0045] More specifically, the 40D / 12F full-dull nylon 6 and 40D / 12F semi-dull nylon 6 are knitted in an alternating 1:2 arrangement.

[0046] More specifically, nylon 6 accounts for 70% of the total weight of the fabric, and elastic spandex yarn accounts for 30% of the total weight of the fabric, with a mass ratio of full-dull nylon 6 to semi-dull nylon 6 of 1:2.

[0047] Specifically, the curl rate for 40D / 12F full-dull nylon 6 and 40D / 12F semi-dull nylon 6 is 45%.

[0048] More specifically, the threading rate for GB1 hackling was 100%, and the threading rate for GB2 hackling was 97%. Specifically, four needles were used to thread the fabric width completely, with one empty pass, and this was repeated 12 times, resulting in a cumulative width of 1.8 cm. The specific threading was AAAAB, where A represents thread splicing and B represents no thread splicing, and the fabric width correspondingly corresponds to 1.8 m.

[0049] Specifically, the warp-to-weft density product of the above warp-knitted fabric reaches 1650 mesh / square centimeter, the longitudinal density of the above warp-knitted fabric is 55 threads / cm, and the transverse density is 30 threads / cm.

[0050] Example 3 The difference between this embodiment and Embodiment 1 is that the GB1 hackling is threaded through 40D / 24F full-dull nylon 6.

[0051] Example 4 The difference between this embodiment and Embodiment 1 is that the GB1 hackling is threaded through 40D / 48F full-dull nylon 6.

[0052] Example 5 The difference between this embodiment and Embodiment 3 is that this embodiment further includes a method for manufacturing a quick-drying, cool-to-the-touch, and firm warp-knit fabric, specifically including the following steps.

[0053] S1, Preparation: Select a 40D / 12F full-dull nylon 6, 40D elastic spandex yarn, and a warp knitting machine with two hackling holes.

[0054] S2. Weaving: Full dull nylon 6 is passed through GB1, elastic spandex yarn is passed through GB2, and weaving is carried out with the structure of Example 3 to obtain gray fabric.

[0055] S3, dyeing.

[0056] S31, flat-width water washing: Flat-width water washing is performed to achieve an oil removal effect, followed by high-temperature shaping.

[0057] S32, Pre-shaping of gray cloth: Pre-shaping treatment is performed on the fabric after weaving, with an over-feed amount of 20%, a vehicle speed of 22 m / min, and a pre-shaping temperature of 180-200°C, preferably 190°C.

[0058] Performing a high-temperature pre-shaping before dyeing effectively mitigates the formation of creases and creases in the fabric due to its elasticity during the dyeing process, and ensures that the fabric has the appropriate degree of crispness.

[0059] S33, Overflow Dyeing: The dyeing process includes a moisture absorption and discharge stage, a coloring stage, and a post-treatment stage.

[0060] In the moisture absorption and discharge finishing stage, the bath ratio is 1:10, a water absorption and discharge aid is added at a mass percentage of 2%, and it is uniformly stirred. The fabric is then placed in the dyeing vat, the dyeing vat temperature is raised to 50-55°C at a heating rate of 1-3°C / min, and the temperature is maintained for 10-15 minutes. Next, the temperature is raised to 55-60°C at a heating rate of 0.5-1.5°C / min, the temperature is maintained for 10-15 minutes, and then the temperature is lowered to 40-45°C at a cooling rate of 2°C / min, and the liquid is discharged.

[0061] Preferably, the dyeing bath temperature is raised to 55°C at a heating rate of 2°C / min, maintained for 10 minutes, then raised to 55°C again at a heating rate of 1°C / min, maintained for 10 minutes, and then cooled to 40°C at a cooling rate of 2°C / min before draining the liquid.

[0062] Specifically, the above water absorption and discharge aid is an emulsion consisting of ternary copolymer block hydrophilic aminosilicone oil, glacial acetic acid, and water. Of these, the amount of glacial acetic acid added is 3% of the weight of the ternary copolymer block hydrophilic aminosilicone oil, and the amount of water added is 7 times the mass of the ternary copolymer block hydrophilic aminosilicone oil.

[0063] Of these, the ternary copolymer block hydrophilic aminosilicone oil is a conventional reagent.

[0064] In this embodiment, by performing moisture absorption and release treatment before dyeing, the wettability and hydrophilicity of the fabric are improved, making it easier for the fabric to absorb and release moisture, and giving the fabric excellent quick-drying properties. At the same time, because nylon fibers themselves have excellent hydrophobicity, the dye does not penetrate and disperse uniformly during the dyeing process. By adding ternary copolymer block hydrophilic aminosilicone oil, the wettability of the nylon fibers is effectively improved, allowing the dye to dye the fibers more easily and uniformly, and improving the color fastness of the dye.

[0065] In the coloring stage, the gray cloth and dye solution from the moisture absorption and release finishing stage are placed in the dyeing tank, with a bath ratio of 1:10. The dye solution contains a wrinkle inhibitor, acid dye, chelating agent, and water. It is heated to 40-45°C, then the dyeing tank temperature is raised to 55-65°C at a rate of 0.5°C / min, the pH is adjusted to 4-5 with acetic acid, and it is kept warm for 10-15 minutes. The temperature is then raised to 75-85°C at a rate of 0.5°C / min and kept warm for 10-15 minutes. The temperature is then raised to 90-100°C at a rate of 0.5°C / min and kept warm for 40-45 minutes. The temperature is then lowered to 55-60°C at a rate of 1.5-2°C / min, a fixing agent is added, and it is kept warm for 20-30 minutes before the liquid is drained.

[0066] Preferably, the dye solution contains a wrinkle inhibitor, an acid dye, a chelating agent, and water. The solution is heated to 42°C, then the temperature of the dyeing tub is raised to 60°C at a rate of 0.5°C / min, the pH is adjusted to 5 with acetic acid, the solution is kept warm for 10 minutes, the temperature is further raised to 80°C at a rate of 0.5°C / min, the solution is kept warm for 10 minutes, the temperature is further raised to 100°C at a rate of 0.5°C / min, the solution is kept warm for 45 minutes, then the temperature is lowered to 55°C at a rate of 1.5°C / min, a fixing agent is added, the solution is kept warm for 20 minutes, and the liquid is drained.

[0067] In this embodiment, by adding a wrinkle inhibitor during dyeing and a water absorption / discharge aid after dyeing, the temperature is gradually increased to organically combine the colorfastness, firmness, quick-drying properties, and coolness of the fabric, thereby demonstrating the advantages of each. This not only aligns with the current development trends in functional warp-knitted fabrics but also represents innovation in the functional field, increasing the added value of the product, meeting the needs of the apparel market for the fabric, and offering excellent market prospects.

[0068] Next, the process moves to the post-treatment stage, where Na2CO3 and water are added, with a bath ratio of 1:8 and an alkaline solution concentration of 10g / L. The temperature is linearly increased to 50-60°C at a heating rate of 3-4°C / min, followed by 10-15 minutes of incubation. Then, the temperature is linearly increased to 70-85°C at a heating rate of 3-4°C / min, followed by 10-15 minutes of washing. Finally, the temperature is linearly decreased to 40-60°C at a cooling rate of 2-3°C / min, and the liquid is discharged.

[0069] Preferably, the alkaline solution concentration is 10 g / L, and the temperature is linearly increased to 55°C at a heating rate of 3.5°C / min, followed by holding the temperature for 15 minutes, then linearly increasing the temperature to 75°C at a heating rate of 3.5°C / min, washing for 10 minutes, and then linearly decreasing the temperature to 50°C at a cooling rate of 2.5°C / min before draining the liquid.

[0070] In this embodiment, by performing post-treatment after coloring, adding a Na2CO3 solution, and coordinating with a gradual increase in temperature, impurities and rough areas on the fabric surface can be gradually removed, thereby reducing the stiffness of the fabric and improving the wearer's comfort.

[0071] In this embodiment, the bath ratios in the moisture absorption and discharge finishing stage, the coloring stage, and the post-treatment stage are all weight ratios of the fabric to the added liquid.

[0072] Specifically, the wrinkle-preventing agent is a polyacrylamide polymer, and its concentration is 20 g / L.

[0073] Specifically, the chelating agent is at least one selected from polyacrylic acid, polyepoxysuccinic acid, polyaspartic acid, and ethylenediaminedi-o-phenylacetic acid, preferably polyaspartic acid, and the concentration of the chelating agent is 1 g / L.

[0074] Specifically, the acid dye is true-blue18-4018TPG, and its mass percentage is 2%.

[0075] Specifically, the above-mentioned adhesive is a standard adhesive, and its concentration is 1.8 g / L.

[0076] S34, Dehydration: Place the dyed semi-finished product into a centrifugal dehydrator and dehydrate for 8 minutes. After dehydration, maintain a uniform moisture content on the fabric surface to prepare for subsequent processes.

[0077] S35, Cutting and finishing: Cutting and finishing are performed on the semi-finished products after dewatering.

[0078] S36, Flattening and drying: Set the temperature to 120°C, the cloth speed to 15 m / min, and the overfeed to 5%.

[0079] S37, Opening and Shaping: Set the shaping temperature to 140°C, the speed to 22 m / min, and the oversupply to 15%.

[0080] Comparative Example 1 The difference between this comparative example and Example 1 is that no winding treatment is performed on both sides of the fabric width.

[0081] Comparative Example 2 The difference between this comparative example and Example 1 is that the curl rate of the 40D / 12F full-dull nylon 6 is set to 50%.

[0082] Comparative Example 3 The difference between this comparative example and Example 1 is that the curl rate of the 40D / 12F full-dull nylon 6 is set to 20%.

[0083] Comparative Example 4 The difference between this comparative example and Example 5 is that the moisture absorption and release processing step is omitted.

[0084] Comparative Example 5 The difference between this comparative example and Example 5 is that the coloring step is performed first, followed by the moisture absorption and release finishing step.

[0085] Performance testing The moisture absorption and quick-drying properties were measured according to GB / T21655.1-2008 "Evaluation of Moisture Absorption and Quick-Drying Properties of Textiles," and the test results are shown in Table 1.

[0086] Tactile Performance Test: Participants closed their eyes and touched the prepared fabric, evaluating it in groups of 5-10 people. The evaluation was conducted according to various textures, and the specific evaluation method was as follows: Based on smoothness and firmness, the fabric was divided into five levels. Level 1 was the worst, with a hard texture and poor smoothness. Level 5 was the best, with smoothness and high firmness. Of these, Level 5: Very good, Level 4: Good, Level 3: Average, Level 2: Slightly bad, Level 1: Bad. The test results are shown in Table 1.

[0087] The wash colorfastness test was conducted according to the national standard GB / T3921.1-1997 "Woven Colorfastness Test, Wash Colorfastness Test," measuring the wash colorfastness of the samples, and the test results are shown in Table 1.

[0088] Table 1 JPEG0007869277000001.jpg119170

[0089] As can be seen from Examples 1, 3-4 and Comparative Examples 2-3, if the curl rate of nylon 6 is too high or too low, it greatly affects the quick-drying properties and feel of the fabric, and the optimal curl rate for nylon 6 is 45%.

[0090] As can be seen from Example 1 and Comparative Example 1, if the fabric is not treated to prevent curling on both sides of its width, the quick-drying properties, colorfastness, and texture of the fabric will all decrease.

[0091] As can be seen from Examples 5-7 and Comparative Examples 4-5, the dyeing treatment step in this application can significantly improve the colorfastness, washability, quick-drying properties, and feel of the fabric.

[0092] Although the present invention is disclosed as described above, it is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention, and therefore the claims of the present invention are equivalent to those limited to the patent claims.
