Description

Technical Field

[0001] The utility model relates to the technical field of textile clothing, in particular to a quick-drying cool and crisp warp knitted fabric. Background Art

[0002] Weaving processes include weaving (also known as shuttle weaving), knitting, braiding and non-woven. Knitting is divided into warp knitting and weft knitting. Warp knitting is a textile process belonging to the knitting field. One or several groups of parallel yarns are fed into all the working needles of the machine in the warp direction to form a knitted fabric at the same time. This method is called warp knitting, and the knitted fabric formed is called warp knitted fabric.

[0003] The warp knitted fabrics in the prior art have the following problems: (1) general warp knitted fabrics have average moisture absorption. When worn on the body, it is difficult to quickly absorb sweat, and the drying speed is slow, which is difficult to meet people's needs; (2) the fabric has poor stiffness and cannot meet user needs; (3) the fabric has poor elasticity and is very uncomfortable for users to wear.

[0004] In view of this, this application is hereby filed. Utility Model Content

[0005] In view of this, the utility model aims to provide a quick-drying cool and stiff warp knitted fabric to solve the problem that the fabrics in the prior art cannot simultaneously take into account quick-drying cool feeling, stiffness and elasticity.

[0006] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0007] A quick-drying, cool, and crisp warp-knitted fabric, the warp-knitted fabric is woven by at least two combs, GB1 and GB2. The yarns used by the GB1 comb are high-mechanical elastic synthetic fiber filaments with round or special-shaped cross-sections, and the yarns used by the GB2 comb are elastic polyurethane filaments. The thickness of the high-mechanical elastic synthetic fiber filaments is 20 to 50D, and the thickness of the elastic polyurethane filaments is less than or equal to 55D.

[0008] Among them, when the cross-section of the high mechanical elastic synthetic fiber filament is a circular cross-section, its structure is a hollow type. This setting has good air permeability and improves the quick-drying and cool feeling of the fabric.

[0009] Preferably, the cross-section of the high mechanical elastic synthetic fiber filament is a special-shaped cross-section. This structure enables the fiber filament to have a larger 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, he will experience quick-drying and cool feeling. At the same time, the high curl rate of the high mechanical elastic synthetic fiber filament can make the fabric have higher stiffness. The fabric woven by the high mechanical elastic synthetic fiber filament and the elastic spandex filament has better elasticity, thereby improving the user's wearing comfort.

[0010] Furthermore, the fineness of the high mechanical elastic synthetic fiber filament is 12 to 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, cool and crisp performance of the fabric. Under the same fineness, the more monofilaments there are, the larger the F number is, which means that the number of fine yarns in the yarn is more. On the one hand, the area of ​​contact between the fiber and the air is large, which may increase the moisture conduction and quick-drying performance of the fabric, which is conducive to the evaporation and diffusion of water on the surface of the yarn. At the same time, the fabric can also dissipate heat better, so that the fabric improves the quick-drying and cool feeling of the fabric. On the other hand, the hand feels softer and the yarn structure is more compact, making the fabric crisp and not hard, and the fabric is flat and not easy to deform;

[0012] 2. However, the more monofilaments there are, on the one hand, the fabric will be too thick and not breathable, which will reduce the quick-drying and cool feeling of the fabric. On the other hand, the weaving performance of the yarn in warp knitting will decrease, because the number of monofilaments is easy to diverge; it is easy to produce hair during warping, and hair during warping will increase the probability of yarn breakage during weaving; in addition, if the monofilaments are easy to diverge during weaving, some monofilaments cannot be fed into the needle hook, resulting in yarn breakage.

[0013] Furthermore, the curl shrinkage rate of the high mechanical elastic synthetic fiber filament must be greater than 25%, preferably, the curl shrinkage rate of the high mechanical elastic synthetic fiber filament is 25-45%. The significance of the curl shrinkage rate in the selection of high mechanical elastic synthetic fiber filament:

[0014] 1. The curl shrinkage rate has a great influence on the quick-drying, cool and crisp performance of the fabric. The greater the curl shrinkage rate, firstly, the more gaps between the fibers, which is conducive to the diffusion and evaporation of water inside the fabric, and improves the quick-drying performance of the fabric; secondly, more air layers are formed on the surface of the fabric, which helps to increase the contact area between the fabric and the air, thereby improving the heat dissipation performance of the fabric; thirdly, the fiber can quickly return to its original state when subjected to external force, which helps to maintain the crispness of the fabric.

[0015] 2. However, when the curl shrinkage rate is too high, the gaps between the fibers may be too tight, the quick-drying coolness is reduced, and it is easy to produce excessive deformation, reducing the stiffness. Too dense fiber gaps will also reduce the contact area between the dyeing liquid and the fiber, resulting in poor dyeing efficiency and low color fastness.

[0016] Furthermore, the yarn full threading rate of the GB1 comb bar and the GB2 comb bar must reach 95% or above, the yarn threading method of the GB1 comb bar is full threading, and the yarn threading method of the GB2 comb bar is not full threading, and the yarns of the GB1 comb bar and the GB2 comb bar can be fed in the same direction or in the opposite direction.

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

[0018] In this setting, the yarn used for the GB1 combing bar must have a larger curl shrinkage rate. Combined with the movement mode of the GB1 combing bar and the GB2 combing bar and the feeding direction of the yarn, the fabric maintains the gap between the yarns, further enhancing the air permeability of the fabric, and can achieve good stiffness and quick-drying cool performance. Among them, high mechanical elastic synthetic fiber filaments can achieve a good stiffness effect under the process of 26-35 horizontal rows / inch on the machine density.

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

[0020] Furthermore, the special-shaped cross-section of the high mechanical elastic synthetic fiber filament includes one of a cross shape, a Y shape, and a pentagonal shape.

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

[0022] Furthermore, the specific threading method of the anti-curling structure is to use 4 to 5 needles to fully thread the yarn on both sides of the door width, and to use empty threading once, and this cycle is repeated 10 to 12 times, with a cumulative width of 1.8 to 2 cm.

[0023] This setting prevents the fabric from curling, improves the smoothness, crispness, quick-drying and coolness of the fabric, and can also avoid problems such as streaking, uneven coloring and wrinkles during dyeing, greatly reducing production costs and the failure rate.

[0024] Furthermore, the high mechanical elastic synthetic fiber filament is composed of 40D / 12F semi-dull nylon 6 and 40D / 12F full-dull nylon 6, the GB1 comb is pierced with 40D / 12F semi-dull nylon 6 and 40D / 12F full-dull nylon 6, the elastic polyurethane filament is spandex yarn, the GB2 comb is pierced with spandex yarn, wherein the arrangement of the semi-dull nylon 6 and the full-dull nylon 6 is a 1:2 staggered arrangement.

[0025] In this setting, the selection of yarn thickness and fineness of nylon 6, as well as the staggered setting can increase the gaps in the fabric, improve the air permeability of the fabric, and thus enhance the quick-drying property of the fabric. In addition, the setting of semi-dull nylon and full-dull nylon makes the fabric have a micro-texture on one side and a smoothness on the other side, making the fabric more attractive.

[0026] Furthermore, the warp knitted fabric is woven using a machine model selected from the group consisting of Tricot HKS-2SE and HKS-2SEPLUS.

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

[0028] Furthermore, the weight percentage of the high mechanical elastic 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%.

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

[0030] Furthermore, the warp and weft density product of the warp knitted fabric reaches 1500 to 2000 meshes per square centimeter.

[0031] Furthermore, the warp knitted fabric has a longitudinal density of 40 to 60 yarns / cm and a transverse density of 27 to 33 yarns / cm.

[0032] The product of the warp and weft density in this setting makes the yarns arranged appropriately and closely, the structure is stable, and the fabric has good stiffness. In addition, sweat can be absorbed and diffused more quickly through the tiny channels between the yarns, which helps quick drying, while reducing air flow and heat exchange, giving people a cool feeling.

[0033] Furthermore, the high mechanical elasticity synthetic fiber filament and the elastic polyurethane filament have the same denier.

[0034] Compared with the prior art, the quick-drying cool and crisp warp knitted fabric described in the utility model has the following advantages:

[0035] (1) The utility model adopts high mechanical elasticity synthetic fiber filaments with special-shaped 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 water on the fiber surface. When the wearer wears the fabric, he will experience a quick-drying and cool feeling. At the same time, the high curl rate of the high mechanical elasticity synthetic fiber filaments can make the fabric have a higher stiffness. The fabric woven from the high mechanical elasticity synthetic fiber filaments and the elastic spandex filaments has good elasticity, which improves the comfort of the user.

[0036] (2) The yarn used in the GB1 comb bar of the utility model is a high mechanical elastic synthetic fiber filament, and the curling 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 movement, the gap between the yarns of the fabric is maintained, which further enhances the air permeability of the fabric and can achieve good stiffness and quick-drying coolness. Among them, the high mechanical elastic synthetic fiber filament can achieve a good stiffness effect under the process of 26-35 rows / inch of machine density;

[0037] 2) The anti-curling structure in the utility model can prevent the fabric from curling, improve the smoothness, crispness, quick-drying and cool feeling of the fabric, and can also avoid the problems of stripe printing, uneven coloring and wrinkles during dyeing, greatly reducing production costs and reducing the failure rate.

[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 and crisp warp knitted fabric, which specifically includes the following steps:

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

[0062] S2, weaving: wearing full dull nylon 6 on GB1, wearing elastic spandex yarn on GB2, and weaving using the organizational structure in Example 3 to obtain a grey cloth;

[0063] S3, dyeing and finishing:

[0064] S31, open width water washing: open width water washing is to achieve the effect of oil removal, and then high temperature shaping;

At the same time, nylon fiber itself has good hydrophobicity, which will make it difficult for the dye to penetrate and disperse evenly during the dyeing process. The addition of ternary copolymer block hydrophilic amino silicone oil can effectively improve the wetting properties of nylon fiber, making it easier for the dye to be evenly dyed onto the fiber, thereby improving the color fastness of the dyeing.

[0073] In the coloring stage, the grey cloth and dye liquor in the moisture absorption and perspiration finishing stage are placed in a dyeing vat, wherein the bath ratio is 1:10; the dye liquor comprises an anti-wrinkle agent, an acid dye, a chelating agent, and water, and is heated to 40-45°C, and then the temperature of the dyeing vat is raised to 55-65°C at a heating rate of 0.5°C / min, the pH is adjusted to 4-5 with acetic acid, and the temperature is kept for 10-15min, and then the temperature is raised to 75-85°C at a heating rate of 0.5°C / min, and the temperature is kept for 10-15min, and then the temperature is raised to 95-105°C at a heating rate of 0.5°C / min, and the temperature is kept for 40-45min, and then the temperature is raised to 55-60°C at a cooling rate of 1.5-2°C / min, a fixing agent is added, and the temperature is kept for 20-30min, and the liquid is discharged;

[0074] Preferably, the dye liquor comprises an anti-wrinkle agent, an acid dye, a chelating agent, and water, which is heated to 42°C, and then the temperature of the dye vat is raised to 60°C at a heating rate of 0.5°C / min, the pH is adjusted to 5 with acetic acid, and the temperature is kept warm for 10 minutes, and then the temperature is raised to 80°C at a heating rate of 0.5°C / min, and the temperature is kept warm for 10 minutes, and then the temperature is raised to 100°C at a heating rate of 0.5°C / min, and the temperature is kept warm for 45 minutes, and then the temperature is raised to 55°C at a cooling rate of 1.5°C / min, a fixing agent is added, the temperature is kept warm for 20 minutes, and the liquid is drained.

[0075] In this embodiment, by adding an anti-wrinkle agent during dyeing and adding a water absorption and perspiration aid after dyeing, and by staged heating, the color fastness, crispness, quick drying and cool feeling of the fabric can be organically combined to give 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 functional field, increases the added value of the product, meets the demand for the fabric in the clothing market, and has a good market prospect.

[0076] Then, enter the post-treatment stage, add Na2CO3 and water, where the bath ratio is 1:8, the alkali solution concentration is 10g / l, and the temperature is linearly increased to 50-60°C at a heating rate of 3-4°C / min, and then kept warm for 10-15min; then the temperature is linearly increased to 70-85°C at a heating rate of 3-4°C / min, washed for 10-15min, and linearly cooled to 40-60°C at a cooling rate of 2-3°C / min, and the liquid is discharged.

[0078] In this embodiment, post-treatment is performed after coloring, and Na2CO3 solution is added and the temperature is increased in stages, which can slowly remove impurities and rough parts on the surface of the fabric, making the fabric crisp and not hard, thereby improving the comfort of users.

[0079] In the moisture absorption and perspiration finishing stage, coloring stage, and post-treatment stage in this embodiment, the bath ratio is the weight ratio of the fabric to the added liquid.
