Description

Technical Field

[0001] The present application relates to the technical field of textile materials, and in particular to a comfortable flash-drying fabric and a preparation method thereof. Background Art

[0002] As people's living standards steadily improve, the importance of exercise in shaping a healthy body and improving the quality of life has become increasingly prominent. This has prompted consumers to put forward higher functional demands on sportswear, underwear and other close-fitting clothing. Especially in high-intensity sports scenes, if the large amount of sweat secreted by the body cannot be quickly dissipated, people will feel obvious discomfort. Therefore, the market demand for functional clothing that can effectively solve this problem is also rising.

[0003] Conventional quick-drying products, in hot and humid conditions, will block the gaps in the fabric due to the water film caused by sweat, greatly reducing the breathability of clothing in hot and humid conditions. Generally, the fabric is woven to have a variety of mesh shapes to improve the breathability of the fabric in hot and humid conditions, or to achieve rapid evaporation of water through a one-way moisture conduction method to achieve a comfortable effect for the human body. However, the fabric style is fancy and easy to cause dew points. After the human body sweats violently after strenuous exercise, the fabric pores cannot change, and the fabric does not have time to evaporate the sweat, which still affects a certain degree of comfort.

[0004] Therefore, the existing wet heat quick-drying fabrics still need to be studied. Summary of the invention

[0005] The present application aims to solve the technical problems existing in the prior art at least to a certain extent. To this end, the present application proposes a comfortable flash-drying fabric and a preparation method thereof. The comfortable flash-drying fabric utilizes its ability to intelligently adjust the pores of the fabric and its moisture conduction performance to effectively achieve moisture absorption and quick drying effects in different hot and humid environments. At the same time, the fabric also has good elasticity and skin-friendly flatness, thereby providing the wearer with an excellent comfortable experience.

[0006] In the first aspect of the present application, the present application proposes a comfortable flash-dry fabric. According to an embodiment of the present application, the comfortable flash-dry fabric comprises a first yarn and a second yarn; the first yarn is a core-spun yarn, and the outer fiber is a parallel composite fiber with a peanut-shaped cross-section, heat-generating performance and deformation under external heat and moisture stimulation; the second yarn comprises an elastic polyester fiber.

[0007] In the comfortable flash-drying fabric of the present application, the difference in the amount of wet expansion and thermal expansion deformation of the parallel composite fibers that have heat-generating properties and are deformed by external heat and humidity stimulation is used to adjust the fabric pores. In a hot and humid state, the pores of the fabric can be opened to prevent the fabric from being affected by the water film, so that it can still maintain better air permeability in a hot and humid state, and the moisture and heat of the fabric are also quickly discharged; in dry and cold conditions, the pores of the fabric can be closed to reduce the loss of heat and moisture. Therefore, in an environment where the cold / hot, dry / wet state switches, the human body can be kept continuously comfortable through the intelligent adjustment of the fabric pores.

[0008] However, the fabric woven only with the first yarn has the problem of insufficient elasticity, which will reduce the fit and comfort of the fabric, limit the freedom of movement, create a sense of tightness or restraint, and affect the wearing experience. To solve this problem, the present application combines elastic fiber with the first yarn to enhance the elasticity of the fabric. However, not all elastic fibers are suitable, such as spandex, whose excessive elastic shrinkage will reduce the heat and moisture regulation function of the first yarn. In contrast, elastic polyester fiber is woven with the first yarn, which can not only improve the elasticity of the fabric and ensure smoothness against the skin, but also has moisture conduction performance, so that the fabric can achieve better heat and moisture regulation and quick-drying effects.

[0009] According to an embodiment of the present application, the comfortable flash-drying fabric may also have the following additional technical features:

[0010] According to an embodiment of the present application, the elastic polyester fiber includes at least one of polytrimethylene terephthalate and polybutylene terephthalate, preferably Sorona.

[0011] According to an embodiment of the present application, the first yarn content in the comfortable flash-dry fabric is greater than the second yarn content.

[0012] According to an embodiment of the present application, the content of the first yarn in the comfortable flash-dry fabric is 55% to 75%, and the content of the second yarn in the comfortable flash-dry fabric is 25% to 45%.

[0013] According to an embodiment of the present application, the denier of the first yarn is 50D-150D.

[0014] According to an embodiment of the present application, the number of filaments of the first yarn is 36F to 144F.

[0015] According to an embodiment of the present application, the denier of the second yarn is 30D-70D.

[0016] According to an embodiment of the present application, the number of filaments of the second yarn is 48F-72F.

[0017] According to an embodiment of the present application, the core yarn of the core-spun yarn is a synthetic fiber filament.

[0018] According to an embodiment of the present application, the comfortable flash-dry fabric is a double-layer fabric, wherein the first layer is woven from a first yarn, and the second layer is woven from a second yarn.

[0019] According to an embodiment of the present application, the comfortable flash-dry fabric is a ribbed structure.

[0020] In another aspect of the present application, the present application proposes a method for preparing the above-mentioned comfortable flash-drying fabric. According to an embodiment of the present application, the method comprises: weaving the first yarn and the second yarn to obtain the comfortable flash-drying fabric.

[0021] According to an embodiment of the present application, the weaving includes: the 1st and 3rd needles form loops, and the lower needles form loops; the 2nd, 4th, 6th, 8th, 10th and 12th needles form loops; the 5th, 7th, 9th and 11th needles form loops; 2 needles and 12 loops constitute a complete cycle; wherein the upper needles use the first yarn and the lower needles use the second yarn.

[0022] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. DETAILED DESCRIPTION

[0027] The present application proposes a comfortable flash-drying fabric and a preparation method thereof, which will be described in detail below.

[0028] Comfortable flash-dry fabric

[0029] In one aspect of the present application, the present application proposes a comfortable flash-dry fabric. According to an embodiment of the present application, the comfortable flash-dry fabric comprises a first yarn and a second yarn; the first yarn is a core-spun yarn, and the outer fiber is a parallel composite fiber with a peanut-shaped cross-section, heat-generating performance and deformation under external heat and moisture stimulation; the second yarn comprises an elastic polyester fiber.

[0030] The first yarn of the comfortable flash-drying fabric of the present application is core-spun yarn, which includes core yarn and outer fiber (also called heat-moisture responsive fiber) obtained by spinning parallel spinning components. The parallel composite fiber is a peanut-shaped cross-section, and the parallel composite fiber is composed of low thermal expansion coefficient and high thermal expansion coefficient fiber. The difference in the amount of wet expansion and thermal expansion deformation caused by the low thermal expansion coefficient and high thermal expansion coefficient of the parallel composite fiber in response to external heat and moisture stimulation is used to adjust the pores of the fabric. In a hot and wet state, the pores of the fabric can be opened so that the fabric is not affected by the water film, so that it can still maintain better breathability in a hot and wet state, and the moisture and heat of the fabric are also quickly discharged; under dry and cold conditions, the pores of the fabric can be closed to reduce the loss of heat and moisture. Therefore, in an environment where the cold / hot and dry / wet states are switched, the human body can be kept continuously comfortable through the intelligent adjustment of the pores of the fabric.

[0031] However, the fabric woven only with the first yarn has the problem of insufficient elasticity, which will reduce the fit and comfort of the fabric, limit the freedom of movement, create a sense of tightness or restraint, and affect the wearing experience. To solve this problem, the present application combines elastic fiber with the first yarn to enhance the elasticity of the fabric. However, not all elastic fibers are suitable, such as spandex, whose excessive elastic shrinkage will reduce the heat and moisture regulation function of the first yarn. In contrast, elastic polyester fiber is woven with the first yarn, which can not only improve the elasticity of the fabric and ensure smoothness against the skin, but also has moisture conduction performance, so that the fabric can achieve better heat and moisture regulation and quick-drying effects.

[0032] According to an embodiment of the present application, the elastic polyester fiber includes at least one of polytrimethylene terephthalate and polybutylene terephthalate. The above-mentioned elastic polyester fiber can not only improve the elasticity of the fabric and ensure the smoothness against the skin, but also has moisture conduction performance, so that the fabric can achieve a better quick-drying effect while maintaining thermal and moisture regulation. Among them, Sorona has a better effect. Sorona is a material made of two main raw materials, 1,3-propylene glycol (PDO) and PTA (or DMT). It can give the fabric a soft feel, comfortable stretch and recovery, and will not hinder the thermal and moisture regulation ability of the first yarn. It also has moisture conduction performance, so that the fabric can quickly conduct moisture and dry quickly.

[0033] According to an embodiment of the present application, the first yarn content in the comfortable flash-dry fabric is greater than the second yarn content, thereby improving the breathability of the comfortable flash-dry fabric in a wet state and also providing better elasticity to improve the comfort of the fabric.

[0034] According to an embodiment of the present application, the content of the first yarn in the comfortable flash-dry fabric is 55% to 75%, such as 55%, 60%, 65%, 70%, 75%, and the content of the second yarn in the comfortable flash-dry fabric is 45% to 25%, such as 45%, 40%, 35%, 30%, 25%, and can be specifically measured by weight. As a result, the comfortable flash-dry fabric has good hand feel and elasticity, and can also achieve good quick-drying and moisture absorption and breathability.

[0035] According to an embodiment of the present application, the denier of the first yarn is 50D-150D, such as 50D, 60D, 70D, 80D, 90D, 100D, 110D, 120D, 130D, 140D, 150D. Thus, while ensuring that the fabric has good thermal and moisture permeability and softness, it can also maintain sufficient strength and wear resistance.

[0036] According to an embodiment of the present application, the number of filaments of the first yarn is 36F to 144F, such as 36F, 40F, 50F, 60F, 80F, 100F, 120F, 140F, 144F. Thus, the uniformity and consistency of the yarn are improved, so that the surface of the fabric is smooth and the texture is clear, thereby improving its appearance quality.

[0037] According to an embodiment of the present application, the denier of the second yarn is 30D to 70D, such as 30D, 40D, 50D, 60D, and 70D. The denier number is an indicator of the thickness of the yarn. A lower denier number indicates a thinner yarn, and a higher denier number indicates a thicker yarn. The second yarn with the above denier number can make the fabric have the advantages of better softness, heat and moisture permeability, elasticity, and durability.

[0038] According to an embodiment of the present application, the number of filaments of the second yarn is 48F to 72F, such as 48F, 50F, 55F, 60F, 65F, 70F, and 72F. As a result, the second yarn has good uniformity and consistency, making the surface of the fabric smoother and the texture clearer, thereby improving its appearance quality. At the same time, this yarn is more stable during the weaving process, reducing the phenomenon of hairiness and broken filaments, and enhancing the durability and anti-pilling properties of the fabric.

[0039] According to an embodiment of the present application, the core yarn of the core-spun yarn is a synthetic fiber filament. Exemplarily, the synthetic fiber filament is any one of polyester filament, nylon filament or spandex filament.

[0040] According to an embodiment of the present application, the parallel composite fiber is composed of a hydrophilic antibacterial fiber and a hydrophobic photothermal conversion fiber, and the diameter ratio of the hydrophilic fiber to the hydrophobic photothermal conversion fiber is 2.5:1 to 1:2.5. By changing the diameter difference of the two components, the asymmetric structure of the fiber is realized to control the amount of thermal deformation or hygroscopic deformation, and then control the bending deformation, so as to obtain intelligent heat and moisture driven core-spun yarns of different specifications.

[0041] According to an embodiment of the present application, the mass ratio of the synthetic fiber filament to the heat and moisture responsive fiber is 50:50 to 10:90; the fineness of the synthetic fiber filament is 30 to 120 dtex; the fineness of the heat and moisture responsive fiber is 16 to 40 dtex; and the fineness of the intelligent heat and moisture driven core-spun yarn is 16 to 80 tex.

[0042] According to an embodiment of the present application, the hydrophilic fiber includes a hydrophilic polymer, the hydrophobic photothermal conversion fiber includes a hydrophobically modified polymer and a powder having photothermal conversion performance, and the hydrophobically modified polymer is obtained by chemical grafting or copolymerization modification of the hydrophilic polymer;

[0043] Alternatively, the hydrophilic fiber includes a hydrophilic modified polymer, the hydrophobic photothermal conversion fiber includes a hydrophobic polymer and a powder having photothermal conversion performance, and the hydrophilic modified polymer is obtained by modifying the hydrophobic polymer through physical blending or chemical copolymerization.

[0044] This application utilizes the structural similarity of the polymers in the two components to increase the adhesion of the two spinning components at the interface, making it easier to shape the parallel fibers and reducing the difficulty of spinning. In addition, the thermal expansion coefficient or wet expansion coefficient of the polymer obtained by self-hydrophilic or hydrophobic modification is not much different from that of the polymer before modification. When the light and heat adsorption or moisture absorption is very different, a significant difference in deformation will occur, which will drive the bending deformation movement, thereby improving the wrapping tightness of the core yarn, accelerating the loss of moisture and heat, and improving the moisture absorption and quick-drying function.

[0045] According to an embodiment of the present application, the hydrophobic polymer is polyethylene terephthalate; and the hydrophilic modified polymer is obtained by chemical copolymerization of terephthalic acid, ethylene glycol, polyethylene glycol and 1,2-butanediol.

[0046] According to an embodiment of the present application, the hydrophilic polymer is polyvinyl alcohol.

[0047] According to an embodiment of the present application, the hydrophobically modified polymer is obtained by side-chain grafting polymerization of the polyvinyl alcohol and a fluorine-containing acrylic monomer through a microwave-assisted synthesis method.

[0048] According to an embodiment of the present application, the powder having light-to-heat conversion performance is at least one of zirconium carbide powder, cobalt carbide powder, molybdenum carbide powder, magnesium carbide powder, and far-infrared ceramic powder.

[0049] According to an embodiment of the present application, the weight fraction of the powder having light-to-heat conversion performance is 0.1 wt % to 1 wt % of the hydrophobic polymer or the hydrophobically modified polymer.

[0050] The comfortable flash-drying fabric of the present application can be either a single-layer fabric or a double-layer fabric. The present invention uses two kinds of yarns to make double-sided fabrics. Compared with the single-layer fabric prepared by simply using heat and moisture comfortable yarns, it can not only achieve comfortable flash-drying performance, but also has better elasticity to meet the customer's usage needs. According to an embodiment of the present application, the first layer of the double-layer fabric is woven from the first yarn, and the second layer is woven from the second yarn. The first yarn is the skin-contacting surface, which has high flatness, is comfortable and soft, and has heat and moisture regulating functions. The second yarn is on the outside and acts as a moisture-conducting tissue. While letting out moisture during exercise, it uses the moisture-conducting properties of the two-component quick-drying fiber to allow the fabric to quickly conduct moisture and dry quickly.

[0051] According to the embodiment of the present application, the comfortable flash-drying fabric is a ribbed fabric. The lower plate is all arranged with the first yarn to form a flat fabric; the upper plate is made of a needle-containing jacquard fabric, and the fabric has a small hole effect. The combination of upper and lower different styles of fabrics ensures that the fabric is skin-friendly and flat, and the breathability of the fabric in the moisture absorption state is not affected. At the same time, because of the mesh fabric, the specific surface area of ​​the fabric is greatly increased, and the quick-drying effect of the fabric is increased.

[0052] Method for preparing comfortable flash-drying fabric

[0053] In another aspect of the present application, the present application proposes a method for preparing the above-mentioned comfortable flash-drying fabric. According to an embodiment of the present application, the method includes: weaving the first yarn and the second yarn to obtain the comfortable flash-drying fabric. Therefore, the comfortable flash-drying fabric prepared by the method of the present application can achieve moisture absorption and quick-drying effect by intelligently adjusting the fabric pores and unique moisture conduction properties in different hot and humid scenes, while having both elasticity and skin-friendly smoothness, making it extremely comfortable.

[0054] According to the embodiment of the present application, the knitting includes: the 1st and 3rd needles form loops, and the lower needles form tucks; the 2nd, 4th, 6th, 8th, 10th and 12th needles form loops; the 5th, 7th, 9th and 11th needles form loops; 2 needles and 12 loops form a complete cycle; wherein the upper needles use the first yarn, and the lower needles use the second yarn. Thus, the knitted fabric has a better heat-wet quick-drying effect, and at the same time has both elasticity and skin-friendly flatness, making it extremely comfortable.

[0055] According to an embodiment of the present application, the present application provides a method for preparing a first yarn, including: using a hydrophilic polymer as a hydrophilic spinning component, melt-blending a hydrophobic modified polymer obtained by hydrophobic modification of the hydrophilic polymer and a powder having a photothermal conversion performance as a hydrophobic spinning component; or melt-blending a hydrophobic polymer and a powder having a photothermal conversion performance as a hydrophobic spinning component, and using a hydrophilic modified polymer obtained by hydrophilic modification of the hydrophobic polymer as a hydrophilic spinning component. Then a parallel spinning assembly is used to perform melt spinning to obtain an outer fiber. Then the outer fiber and the synthetic fiber filament are subjected to a drawing, roving, and spun yarn process to obtain a first yarn having heat and moisture regulation ability. The present application utilizes the similarity of the two spinning components of the outer fiber to improve the adhesion of the two spinning components at the interface, thereby preparing a parallel composite fiber with strong interface adhesion.

[0056] It should be noted that the features and advantages described above for the comfortable flash-dry fabric are also applicable to the method for preparing the comfortable flash-dry fabric, and will not be repeated here.

[0057] The scheme of the present invention will be explained below in conjunction with the embodiments.

[0071] Example 6

[0072] In this embodiment, a comfortable flash-drying fabric is prepared according to the following method:

[0073] 1. Prepare intelligent heat and moisture driven core-spun yarn according to the method of Example 1 of CN111041636A, and use it as the first yarn;

[0074] 2. Use the intelligent heat and moisture driven core-spun yarn as the first yarn, with a denier of 75D and a filament number of 48F. Use Sorona as the second yarn to weave into a rib structure, with a denier of 30D and a filament number of 48F. Weave the first yarn and the second yarn into a rib structure, with the first yarn used for the upper needle and the second yarn used for the lower needle, and the weaving method is as follows:

[0075] The first and third stitches are circled, and the lower stitches are tucked in a circle;

[0076] The 2nd, 4th, 6th, 8th, 10th and 12th stitches are circled;

[0077] The needles on the 5th, 7th, 9th and 11th routes are circled;

[0078] 2 needles and 12 circuits form a complete cycle.

[0079] In the comfortable flash-dry fabric obtained by knitting, the content of the first yarn is 55%, and the content of the second yarn is 45%.

[0080] Comparative Example 1

[0081] A comfortable flash-drying fabric was prepared according to the method of Example 1, except that the second yarn was replaced with spandex.

[0082] Comparative Example 2

[0083] A comfortable flash-drying fabric was prepared according to the method of Example 1, except that the first yarn was replaced with conventional polyester.

[0084] Test Case

[0085] The performance tests were conducted on the comfortable flash-drying fabrics prepared in Examples 1 to 6 and Comparative Examples 1 and 2, respectively, and the test contents were as follows:

[0086] 1. Air permeability test under different moisture absorption

[0087] Test method: Dry the fabric fully in an environment of 60°C, and test the air permeability of the fabric in a dry state (0% moisture absorption), and at moisture absorption rates of 30%, 50% and 100%.

[0088] The results are shown in Table 2. From the results in the table below, it can be seen that the introduction of the first yarn can improve the basic air permeability and moisture permeability of the fabric, and as the proportion of the first yarn increases, the moisture permeability of the fabric is better. In addition, from Comparative Example 1, it can be seen that after the second yarn is replaced with spandex, the air permeability of the fabric decreases as the moisture absorption increases. This is because the elasticity of spandex is too large, which restricts the deformation ability of the first yarn after being stimulated by heat and moisture, resulting in the formation of a water film on the surface of the fabric after moisture absorption, which reduces its air permeability; from Comparative Example 2, it can be seen that after the first yarn is replaced with conventional polyester yarn, the air permeability of the fabric decreases significantly as the moisture absorption increases, which further proves that the first yarn is conducive to increasing air permeability.

[0089] Table 2 Air permeability test

[0090]

[0091]

[0092] 2. Thermal resistance test under different moisture absorption

[0093] Test method: Fabrics with different moisture absorption are tested according to the test method of national standard GB / T 11048-2008.

[0094] The results are shown in Table 3. From the results in the table below, it can be seen that the introduction of the first yarn can effectively reduce the thermal resistance of the fabric, and as the proportion of the first yarn increases, the thermal resistance of the fabric decreases. In addition, from Comparative Example 1, it can be seen that, similar to the results of the air permeability test, after the second yarn is replaced with spandex, the thermal resistance of the fabric decreases as the moisture absorption increases. This is because the elasticity of spandex is too large, which restricts the deformation ability of the first yarn after being stimulated by heat and moisture, resulting in the formation of a water film on the surface of the fabric after moisture absorption, making it difficult for heat to transfer; from Comparative Example 2, it can be seen that after the first yarn is replaced with conventional polyester yarn, the thermal resistance of the fabric decreases significantly as the moisture absorption increases, which further proves that the first yarn is conducive to reducing the thermal resistance of the fabric.

[0095] Table 3 Thermal resistance test

[0096]

[0097] 3. Moisture absorption and quick-drying test

[0098] Test method: The test method is carried out in accordance with the national standard GB / T21655.1-2023.

[0099] The results are shown in Table 4. From the results in the table below, it can be seen that the introduction of the first yarn can effectively improve the moisture absorption and quick-drying performance of the fabric, and as the proportion of the first yarn increases, the moisture absorption and quick-drying performance of the fabric is better. After the second yarn is replaced with spandex, the moisture absorption and quick-drying properties of the fabric are reduced, indicating that the excessive elasticity of spandex will affect the moisture absorption and quick-drying properties of the fabric. It can be seen from Comparative Example 2 that after the first yarn is replaced with conventional polyester yarn, the moisture absorption and quick-drying properties of the fabric are significantly reduced, which further proves that the first yarn is conducive to reducing the thermal resistance value of the fabric.

[0100] Table 4 Moisture absorption and quick drying test

[0101]

[0102] 4. Fabric rigidity test

[0103] Test method: The test method is carried out in accordance with the national standard GB / T 18318.1-2009.

[0104] The results are shown in Table 5. From the results in the table below, it can be seen that the introduction of the first yarn can effectively improve the softness of the fabric, and as the proportion of the second yarn increases, the softness of the fabric is better. From the test results of Comparative Example 1, it can be seen that after the second yarn is replaced with spandex, the rigidity of Sorona and spandex is relatively close, which has little effect on the softness of the fabric. From Comparative Example 2, it can be seen that after the first yarn is replaced with conventional polyester yarn, the softness of the fabric is significantly reduced, which proves that the first yarn is softer than conventional polyester yarn, which is conducive to reducing and improving the softness of the fabric.
