Description

Technical Field

[0001] This invention relates to the field of textile and apparel technology, and more specifically, to a quick-drying, cool-feeling, and crisp warp-knitted fabric. Background Technology

[0002] Weaving processes include machine weaving (also known as shuttle weaving), knitting, braiding and non-woven fabrics. Knitting is further divided into warp knitting and weft knitting. Warp knitting is a textile process in the field of knitting. It uses one or more sets of parallel yarns to form loops on all the working needles of the machine in the warp direction to form a knitted fabric. This method is called warp knitting, and the resulting knitted fabric is called warp-knitted fabric.

[0003] The existing warp-knitted fabrics have the following problems: (1) The general warp-knitted fabrics have poor moisture absorption. When worn, they are difficult to quickly absorb sweat and the drying speed is slow, which is difficult to meet people's needs; (2) The fabrics have poor stiffness and cannot meet the needs of users; (3) The fabrics have poor elasticity and are very uncomfortable for users to wear.

[0004] Therefore, this application is hereby submitted. Summary of the Invention

[0005] In view of this, the present invention aims to propose a quick-drying, cool-feeling, and crisp warp-knitted fabric to solve the problem that existing fabrics cannot simultaneously achieve quick-drying coolness, crispness, and elasticity.

[0006] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0007] A quick-drying, cool-feeling, and crisp warp-knitted fabric, wherein the warp-knitted fabric is woven from at least two guide bars, GB1 and GB2. The yarn used in the GB1 guide bar is a high mechanical elasticity synthetic fiber filament with a round or irregular cross-section, and the yarn used in the GB2 guide bar is an elastic polyurethane filament. The high mechanical elasticity synthetic fiber filament has a thickness of 20-50D, and the elastic polyurethane filament has a thickness of less than or equal to 55D.

[0008] Among them, when the cross-section of the high mechanical elasticity synthetic fiber filament is circular and its structure is hollow, this setting has good breathability and improves the quick-drying and cool feel of the fabric.

[0009] Preferably, the cross-section of the high mechanical elasticity synthetic fiber filament is an irregular cross-section. This structure gives the fiber filament a large specific surface area. The large contact area between the fiber and the air is conducive to the diffusion and evaporation of moisture on the fiber surface, giving the wearer a quick-drying and cool feeling when wearing the fabric. At the same time, the high crimp rate of the high mechanical elasticity synthetic fiber filament gives the fabric high stiffness. Furthermore, the fabric woven from the high mechanical elasticity synthetic fiber filament and elastic spandex filament has good elasticity, improving the user's wearing comfort.

[0010] Furthermore, the fineness of the highly mechanically elastic synthetic fiber filament is 12–48F. The significance of limiting the number of monofilaments in yarn selection:

[0011] 1. The number of monofilaments (unit F) has a great influence on the quick-drying, cooling and crisp properties of fabrics. At the same fineness, the more monofilaments and the larger the F number, the more fine yarns are in the yarn. On the one hand, the fiber has a larger contact area with the air, which may increase the fabric's moisture-wicking and quick-drying properties, which is conducive to the evaporation and diffusion of moisture on the yarn surface. At the same time, the fabric can also dissipate heat better, which improves the quick-drying and cooling feel of the fabric. On the other hand, the hand feel is softer and the yarn structure is more compact, which makes the fabric crisp but not stiff, smooth and not easy to deform.

[0012] 2. However, the higher the number of monofilaments, the heavier and less breathable the fabric becomes, which reduces its quick-drying and cool feel. On the other hand, the yarn's weaving performance in warp knitting will decrease because the number of monofilaments is more likely to disperse. During warping, fuzz is more likely to be generated, which increases the chance of yarn breakage during weaving. In addition, if the monofilaments are prone to dispersion during weaving, some monofilaments may not be fed into the needle hook, resulting in yarn breakage.

[0013] Furthermore, the crimp shrinkage rate of the high mechanical elasticity synthetic fiber filament must be greater than 25%, preferably 25% to 45%. The significance of limiting the crimp shrinkage rate in the selection of high mechanical elasticity synthetic fiber filaments:

[0014] 1. The curl shrinkage rate has a significant impact on the quick-drying, cooling, and crisp properties of fabrics. The greater the curl shrinkage rate, the more gaps between fibers there are, which facilitates the diffusion and evaporation of moisture within the fabric, improving its quick-drying properties. Secondly, it creates more air layers on the fabric surface, which helps increase the contact area between the fabric and the air, thereby improving the fabric's heat dissipation performance. Thirdly, the fibers can quickly return to their original shape when subjected to external forces, which helps maintain the fabric's crisp properties.

[0015] 2. However, when the crimping shrinkage rate is too high, the gaps between the fibers may be too tight, reducing the quick-drying and cooling sensation, and easily causing excessive deformation, reducing stiffness. The excessively dense fiber gaps will also result in a small contact area between the dyeing solution and the fiber, poor dyeing efficiency, and low color fastness.

[0016] Furthermore, the yarn full-thread rate of GB1 and GB2 must reach 95% or more. The yarn threading method of GB1 is full-thread, while the yarn threading method of GB2 is partial-thread. The yarns of GB1 and GB2 can be fed in the same direction or in opposite directions.

[0017] Furthermore, the GB1 comb movement spacing must be less than or equal to the distance of 3 needles, and its knitting pattern can be open or closed; the GB2 comb movement spacing must be less than or equal to the distance of 2 needles, and its knitting pattern can be open or closed.

[0018] In this setup, the yarn used in the GB1 comb must have a higher crimp shrinkage rate. Combined with the movement of the GB1 and GB2 combs and their direction of yarn feeding, the fabric maintains gaps between yarns, further enhancing its breathability and achieving excellent crispness and quick-drying cooling properties. In particular, high mechanical elasticity synthetic fiber filaments can achieve a good crispness effect under a machine density of 26-35 rows / inch.

[0019] Furthermore, the high mechanical elasticity synthetic fiber filament is 40D / 12F fully dull nylon 6 or 40D / 12F fully dull nylon 66, and the GB1 comb is fully threaded with 40D / 12F fully dull nylon 6 or 40D / 12F fully dull nylon 66. The elastic polyurethane filament is spandex filament, and the GB2 comb is threaded with spandex filament.

[0020] Furthermore, the cross-section of the highly mechanically elastic synthetic fiber filament includes one of the following: cross-shaped, Y-shaped, or pentagonal.

[0021] Furthermore, the warp-knitted fabric includes an anti-rolling structure located on both sides of the fabric width. The width of the anti-rolling structure on either side of the fabric width is 1.8 to 2 cm, corresponding to a fabric width of 1.5 m to 1.8 m.

[0022] Furthermore, the specific threading method of the anti-rolling structure is as follows: 4 to 5 needles are used to fully thread the yarn on both sides of the width, followed by one empty threading, and this cycle is repeated 10 to 12 times, with a cumulative width of 1.8 to 2 cm.

[0023] This setting prevents fabric from curling at the edges, improves the fabric's smoothness, crispness, quick-drying and cool feel, and also avoids problems such as streaks, uneven coloring, and wrinkles during dyeing, greatly reducing production costs and the rate of failures.

[0024] Furthermore, the high mechanical elasticity synthetic fiber filament is composed of 40D / 12F semi-dull nylon 6 and 40D / 12F fully dull nylon 6, with GB1 comb threaded with 40D / 12F semi-dull nylon 6 and 40D / 12F fully dull nylon 6. The elastic polyurethane filament is spandex filament, with GB2 comb threaded with spandex filament. The semi-dull nylon 6 and fully dull nylon 6 are arranged in a 1:2 alternating pattern.

[0025] The selection of yarn thickness and fineness of nylon 6 in this setting, as well as the interlacing, can increase the fabric's porosity, improve its breathability, and thus enhance its quick-drying properties. In addition, the combination of semi-dull and fully dull nylon gives the fabric a micro-textured surface on one side and a smooth surface on the other, making the fabric more attractive.

[0026] Furthermore, the warp-knitted fabric is woven using either the Trico HKS-2SE or HKS-2SEPLUS machine.

[0027] Furthermore, the fabric is woven using a needle gauge of 36-40G.

[0028] Furthermore, the high mechanical elasticity synthetic fiber filament accounts for 70-80% of the total weight of the fabric, and the elastic polyurethane filament accounts for 20-30% of the total weight of the fabric.

[0029] Furthermore, the product of the warp and weft densities of the warp-knitted fabric reaches more than 1100 eyes / square centimeter.

[0030] Furthermore, the product of the warp and weft densities of the warp-knitted fabric reaches 1500-2000 eyes / square centimeter.

[0031] Furthermore, the warp-knitted fabric has a warp density of 40-60 threads / cm and a weft density of 27-33 threads / cm.

[0032] In this setup, the warp and weft density product ensures that the yarns are arranged appropriately and tightly, resulting in a stable structure and good fabric stiffness. In addition, sweat can be absorbed and diffused more quickly through the tiny channels between the yarns, which helps with quick drying. At the same time, it reduces airflow and heat exchange, giving a cool feeling.

[0033] Furthermore, the highly mechanically elastic synthetic fiber filament and the elastic polyurethane filament have the same denier.

[0034] Compared with existing technologies, the quick-drying, cool-feeling, and crisp warp-knitted fabric of this invention has the following advantages:

[0035] (1) The present invention uses high mechanical elasticity synthetic fiber filaments with irregular cross sections. The fiber filaments have a large specific surface area. The large contact area between the fiber and the air is conducive to the diffusion and evaporation of moisture on the fiber surface. When the wearer wears the fabric, they have a quick-drying and cool feeling. At the same time, the high crimp rate of the high mechanical elasticity synthetic fiber filaments can make the fabric have high stiffness. The fabric woven from high mechanical elasticity synthetic fiber filaments and elastic spandex filaments has good elasticity, which improves the comfort of the user.

[0036] (2) The yarn used in the GB1 comb of this invention is a high mechanical elastic synthetic fiber filament. The crimp shrinkage rate of the high mechanical elastic synthetic fiber filament must be greater than 25%. Combined with the movement mode of GB1 and GB2 and the same direction of the fabric, the gap between the yarns is maintained, which further enhances the breathability of the fabric and can achieve good crispness and quick-drying and coolness performance. Among them, the high mechanical elastic synthetic fiber filament can achieve a good crispness effect under the process of machine density of 26-35 rows / inch.

[0037] 2) The anti-curling structure in this invention can prevent the fabric from curling, improve the smoothness, crispness, quick-drying and coolness of the fabric, and also avoid problems such as streaks, uneven coloring and wrinkles during dyeing, which greatly reduces production costs and reduces the rate of failure.

[0040] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0041] Example 1

[0042] like Figure 1 As shown, the present invention provides a quick-drying, cool-feeling, and crisp warp-knitted fabric. The fabric is woven from two guide bars GB1 and GB2 of a warp knitting machine with a gauge of 40G. The machine model is Trico HKS-2SE. The GB1 guide bar is fully threaded with 40D / 12F fully dull nylon 6 with a cross-shaped cross section. The GB1 guide bar is also threaded with 40D elastic spandex yarn. The fully dull nylon 6 accounts for 77% of the total weight of the fabric, and the elastic spandex yarn accounts for 23% of the total weight of the fabric.

[0043] Specifically, the crimp rate of 40D / 12F fully dull nylon 6 is 45%.

[0044] Specifically, the fully dull nylon 6 is knitted at a density of 28 rows / inch. In the structure of the warp-knitted fabric, GB1 and GB2 guide bars are fed in the same direction. The span of GB1 guide bar is 1 needle distance, and its knitting pattern is open. The padding yarn number of GB1 guide bar is 0-1 / 2-1 / / . The span of GB2 guide bar is 1 needle distance, and its knitting pattern is closed. The padding yarn number of GB2 guide bar is 1-0 / 1-2 / / .

[0045] More specifically, the GB1 guide bar uses a full-threading method with a yarn full-threading rate of 100%, while the GB2 guide bar uses a partial-threading method with a yarn full-threading rate of 97%. Specifically, five needles are used for full threading on both sides of the width, followed by one empty threading, and this cycle is repeated 10 times, accumulating a width of 2cm. The specific threading method is AAAAAB, where A represents joining yarn and B represents not joining yarn. The width of the width corresponds to 1.5m.

[0047] Example 2

[0048] like Figure 2 As shown, the present invention provides a quick-drying, cool-feeling, and crisp warp-knitted fabric. The fabric is woven from two guide bars GB1 and GB2 of a warp knitting machine with a needle gauge of 36G. The machine model is Trico HKS-2SEPLUS. The GB1 guide bar is threaded with 40D / 12F fully dull nylon 6 and 40D / 12F semi-dull nylon 6. The cross-section of both the fully dull nylon and the semi-dull nylon is Y-shaped. The GB1 guide bar is threaded with 40D elastic spandex yarn.

[0049] Specifically, the full-dull nylon 6 and semi-dull nylon 6 are knitted at a density of 32 rows / inch. In the structure of the warp-knitted fabric, GB1 and GB2 guide bars are fed in the same direction. The span of GB1 guide bar is 1 needle distance, and its knitting pattern is closed. The padding yarn number of GB1 guide bar is 1-0 / 1-2 / / . The span of GB2 guide bar is 1 needle distance, and its knitting pattern is closed. The padding yarn number of GB2 guide bar is 1-0 / 1-2 / / .

[0050] More specifically, the 40D / 12F fully dull nylon 6 and 40D / 12F semi-dull nylon 6 are arranged in a 1:2 alternating weave.

[0051] More specifically, nylon 6 accounts for 70% of the total weight of the fabric, and elastic spandex accounts for 30% of the total weight of the fabric. The mass ratio of fully dull nylon 6 to semi-dull nylon 6 is 1:2.

[0052] Specifically, the crimp rate of 40D / 12F fully dull nylon 6 and 40D / 12F semi-dull nylon 6 is 45%.

[0053] More specifically, the full yarn threading rate of GB1 comb is 100%, and that of GB2 comb is 97%. Specifically, four needles are used to fully thread the yarn on both sides of the width, followed by one empty thread, and this cycle is repeated 12 times, accumulating a total width of 1.8cm. The specific yarn threading pattern is AAAAB, where A represents joined yarn and B represents unjoined yarn. The width of the width corresponds to 1.8m.

[0054] Specifically, the warp and weft density product of the warp-knitted fabric reaches 1650 eyes / square centimeter, the warp density of the warp-knitted fabric is 55 threads / cm, and the weft density is 30 threads / cm.

[0055] Example 3

[0056] The difference between this embodiment and Embodiment 1 is that GB1 combing uses 40D / 24F fully dull nylon 6.

[0057] Example 4

[0058] The difference between this embodiment and Embodiment 1 is that GB1 combing uses 40D / 48F fully dull nylon 6.

[0059] Example 5

[0060] The difference between this embodiment and Embodiment 3 is that it also includes a method for preparing a quick-drying, cool-feeling, and crisp warp-knitted fabric, which specifically includes the following steps:

[0061] S1. Preparation: Select 40D / 12F fully dull nylon 6, 40D elastic spandex yarn and a two-comb warp knitting machine;

[0062] S2. Weaving: Fully dull nylon 6 is threaded onto GB1, and elastic spandex yarn is threaded onto GB2. The fabric is woven using the structure described in Example 3 to obtain the grey fabric.

[0063] S3, Dyeing and Finishing:

[0064] S31, Flat-width washing: Flat-width washing is to remove oil, followed by high-temperature setting;

[0065] S32. Pre-forming of greige fabric: The woven greige fabric is pre-formed, wherein the overfeed is 20%, the machine speed is 22m / min, and the pre-forming temperature is 180-200℃, preferably 190℃.

[0066] High-temperature pre-setting before dyeing can effectively alleviate the deformation or shrinkage of the microgrooves of nylon with irregular cross-sections in the fabric during the dyeing process, maintaining the three-dimensional structure of the microgrooves, preserving the fabric's high stiffness, and making the fabric more resistant to washing. At the same time, the three-dimensional microgrooves increase the contact area between the fibers and air, thus maintaining the fabric's good quick-drying and cool feel. In addition, the three-dimensional structure of the microgrooves increases the contact area between the dyeing solution and the fibers, which can also improve the dyeing uptake and color fastness of the fabric.

[0067] S33, Overflow dyeing, the dyeing process includes moisture-wicking finishing stage, coloring stage, and post-treatment stage;

[0068] In the moisture-wicking finishing stage, the liquor ratio is 1:10. Add a moisture-wicking agent with a mass fraction of 2%, stir evenly, and arrange the pre-cut fabric in the dyeing vat. Increase the temperature of the dyeing vat to 50-55℃ at a rate of 1-3℃ / min, hold for 10-15min, then increase the temperature to 55-60℃ at a rate of 0.5-1.5℃ / min, hold for 10-15min, and then decrease the temperature to 40-45℃ at a rate of 2℃ / min. Drain the liquid.

[0069] Preferably, the dyeing vat temperature is increased to 55°C at a rate of 2°C / min, held for 10 min, then increased to 55°C at a rate of 1°C / min, held for 10 min, and then decreased to 40°C at a rate of 2°C / min before draining.

[0070] Specifically, the water-absorbing and perspiration-wicking agent is an emulsion composed of ternary copolymer block hydrophilic amino silicone oil, glacial acetic acid, and water, wherein the amount of glacial acetic acid added is 3% of the weight of the ternary copolymer block hydrophilic amino silicone oil; and the amount of water added is 7 times the mass of the ternary copolymer block hydrophilic amino silicone oil.

[0071] Among them, ternary copolymer block hydrophilic amino silicone oil is an existing reagent.

[0072] In this embodiment, by performing a moisture-wicking finishing process before dyeing, the wettability and hydrophilicity of the fabric can be improved, making it easier for the fabric to absorb and release moisture, thus giving the fabric better quick-drying properties. At the same time, nylon fibers themselves have good hydrophobicity, which makes it difficult for dyes to penetrate and disperse evenly during the dyeing process. Adding ternary copolymer block hydrophilic amino silicone oil can effectively improve the wettability of nylon fibers, making it easier for dyes to be evenly applied to the fibers and improving the color fastness of the dyeing.

[0073] In the dyeing stage, the greige fabric from the moisture-wicking finishing stage and the dye liquor are placed in a dyeing vat with a liquor ratio of 1:10. The dye liquor includes an anti-wrinkle agent, acid dye, chelating agent, and water. The temperature is raised to 40-45°C, and then the vat temperature is increased to 55-65°C at a rate of 0.5°C / min. The pH is adjusted to 4-5 with acetic acid and held for 10-15 minutes. The temperature is then increased to 75-85°C at a rate of 0.5°C / min and held for 10-15 minutes. The temperature is then increased to 95-105°C at a rate of 0.5°C / min and held for 40-45 minutes. Finally, the temperature is increased to 55-60°C at a rate of 1.5-2°C / min, a fixing agent is added, and the vat is held for 20-30 minutes before draining.

[0074] Preferably, the dyeing solution includes an anti-wrinkle agent, an acid dye, a chelating agent, and water. The solution is heated to 42°C, then the dyeing vat temperature is increased to 60°C at a rate of 0.5°C / min. The pH is adjusted to 5 with acetic acid, and the solution is held for 10 minutes. The solution is then increased to 80°C at a rate of 0.5°C / min, held for 10 minutes, then increased to 100°C at a rate of 0.5°C / min, held for 45 minutes, and then increased to 55°C at a rate of 1.5°C / min. A fixing agent is added, the solution is held for 20 minutes, and then the solution is drained.

[0075] In this embodiment, by adding an anti-wrinkle agent during dyeing and a water-wicking agent after dyeing, and by using staged heating, the color fastness, stiffness, quick-drying properties, and coolness of the fabric can be organically combined, giving full play to their respective advantages. This not only conforms to the current development trend of functional warp-knitted fabrics, but also innovates in the field of functionality, increases the added value of the product, meets the demand of the apparel market for this fabric, and has a good market prospect.

[0076] Then, in the post-treatment stage, Na2CO3 and water are added, with a bath ratio of 1:8 and an alkali concentration of 10 g / L. The temperature is linearly increased to 50–60 °C at a heating rate of 3–4 °C / min and held for 10–15 min. Then, the temperature is linearly increased to 70–85 °C at a heating rate of 3–4 °C / min and washed for 10–15 min. The temperature is then linearly decreased to 40–60 °C at a cooling rate of 2–3 °C / min, and the liquid is discharged.

[0077] Preferably, the alkali concentration is 10 g / L, and the temperature is linearly increased to 55°C at a heating rate of 3.5°C / min, and then held at that temperature for 15 min; then the temperature is linearly increased to 75°C at a heating rate of 3.5°C / min and washed for 10 min; then the temperature is linearly decreased to 50°C at a cooling rate of 2.5°C / min, and the liquid is discharged.

[0078] In this embodiment, a post-treatment is performed after dyeing. Adding Na2CO3 solution and using segmented heating can slowly remove impurities and rough parts from the fabric surface, making the fabric crisp but not stiff, and improving the user's wearing comfort.

[0079] In this embodiment, the liquor ratio in the moisture-wicking finishing stage, dyeing stage, and post-treatment stage is the weight ratio of the fabric to the added liquid.

[0080] Specifically, the anti-wrinkle agent is a polyacrylamide polymer, and the concentration of the anti-wrinkle agent is 20 g / L.

[0081] Specifically, the chelating agent is selected from at least one of polyacrylic acid, polyepoxysuccinic acid, polyaspartic acid and ethylenediamine di-o-phenylacetic acid. Preferably, the chelating agent is polyaspartic acid, and the concentration of the chelating agent is 1 g / L.

[0082] Specifically, the acid dye is True Blue 18-4018TPG, and the mass fraction of the acid dye is 2%.

[0083] Specifically, the fixing agent is a conventional fixing agent, and the concentration of the fixing agent is 1.8 g / L.

[0084] 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.

[0085] S35, Split fabric processing: Split the dehydrated semi-finished product into widths;

[0086] S36, flat-width drying, temperature 120℃, cloth speed 15m / min, overfeed 5%;

[0087] S37, Opening and setting, setting temperature is 140℃, speed is 22m / min, overfeed 15%.

[0088] Comparative Example 1

[0089] The difference between this comparative example and Example 1 is that the two sides of the flap are not rolled.

[0090] Comparative Example 2

[0091] The difference between this comparative example and Example 1 is that the crimp rate of the 40D / 12F fully dull nylon 6 is 50%.

[0096] Comparative Example 5

[0097] The difference between this comparative example and Example 5 is that the coloring stage is performed first, followed by the moisture-wicking finishing stage.

[0098] Performance testing

[0099] The moisture absorption and quick-drying properties were tested in accordance with GB / T21655.1-2008 "Evaluation of the moisture absorption and quick-drying properties of textiles", and the test results are shown in Table 1.

[0100] Hand feel performance test: After finishing, the fabric was touched with eyes closed. Groups of 5-10 people were assigned a rating based on different hand feel characteristics. The specific rating method was as follows: the hand feel was rated from smoothness to crispness, with a total of 5 levels. Level 1 was the worst, with a stiff feel and poor smoothness. Level 5 was the best, with smoothness and crispness. Specifically, Level 5 was excellent, Level 4 was good, Level 3 was average, Level 2 was slightly poor, and Level 1 was poor. The test results are shown in Table 1.

[0101] The color fastness to washing was tested according to the national standard GB / T3921.1-1997 "Textiles - Tests for color fastness to washing". The test results are shown in Table 1.

[0102] Table 1

[0103]

[0104]

[0105] As can be seen from Examples 1, 3-4 and Comparative Examples 2-3, an excessively large or small crimp rate of nylon 6 has a significant impact on the quick-drying properties and hand feel of the fabric. The optimal crimp rate of nylon 6 is 45%.

[0106] As can be seen from Example 1 and Comparative Example 1, if the edges of the fabric are not hemmed, the quick-drying properties, color fastness, and hand feel of the fabric will all decrease.

[0107] As can be seen from Examples 5-7 and Comparative Examples 4-5, the dyeing process in this application can significantly improve the color fastness, washability, quick-drying properties, and hand feel of the fabric.

[0108] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
