Description

A multidimensional humidity and heat management fabric and its processing method

[0001] This application claims priority to Chinese Patent Application No. 202410785469.4, filed on June 18, 2024, entitled "A Multidimensional Humidity and Heat Management Fabric and Processing Method", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention belongs to the field of textile technology, and in particular relates to a multidimensional humidity and heat management fabric and its processing method. Background Technology

[0003] Moisture management fabrics, with their superior moisture absorption, quick-drying, breathability, and heat dissipation properties, are widely used in underwear, sportswear, protective clothing, and medical apparel. However, moisture management fabrics still face challenges in moisture conduction and heat dissipation that require further improvement. A common technical approach is to modify the fiber structure, utilizing grooved fiber cross-sections to enhance moisture conduction efficiency, such as DuPont's Coolmax fiber, which features a four-groove fiber cross-section. While this type of fabric offers high moisture wicking efficiency, its manufacturing cost is relatively high.

[0004] Another common method is to combine different types of yarns or fabrics, utilizing their differences in water absorption to create a gradient that promotes directional moisture transport. For example, Chinese patent document CN 1985036 A discloses a woven fabric with moisture management properties, comprising a generally uniform woven structure composed of hydrophobic and hydrophilic materials. This woven structure has an internal exposed surface composed of 40% to 70% hydrophobic and hydrophilic materials, and an external exposed surface composed primarily of hydrophilic and hydrophobic materials. This technology achieves directional moisture transfer from the fabric base to the fabric surface by combining hydrophilic and hydrophobic yarns, but the fabric's moisture-wicking and heat-dissipating properties still have room for improvement. Therefore, it is essential to develop a multi-dimensional moisture management fabric that can efficiently manage humidity and heat through a simple and efficient design and processing method.

[0005] Summary of the Invention

[0006] In view of the shortcomings of the prior art as described above, the problem to be solved by the present invention is to provide a multi-dimensional moisture and heat management fabric and processing method. The fabric provided by the present invention has excellent properties such as moisture absorption and quick drying, breathability, and rapid moisture and heat conduction.

[0007] The first aspect of this application provides a multidimensional humidity and heat management fabric, which is woven from at least a first yarn and a second yarn with different hydrophilicities in a double or more longitudinal structure. The multidimensional humidity and heat management fabric has a multi-level pore structure that runs through the longitudinal direction in the transverse direction. The first yarn and the second yarn may be made of the same or different materials.

[0008] The multi-level pore structure includes multiple basic pores and multiple functional pores. The diameter of each functional pore is larger than that of each basic pore. The multiple functional pores are uniformly distributed around each basic pore, and their distribution density is lower than that of the basic pores. The ratio of the total area of ​​the multiple functional pores to the fabric area is no more than 45%. The hydrophilicity of the yarn surrounding each functional pore is higher than that of the yarn surrounding each basic pore.

[0009] This invention creates differentiation between pores by controlling the structure and distribution of basic and functional pores in fabrics, as well as factors such as weaving methods and layer (layout), thereby generating a surface energy gradient. This results in asymmetry in pressure and water transport, enabling efficient conduction of moisture and heat in textiles and providing a solution for the refined design of the thermal, moisture, and breathability management performance of textiles.

[0010] Figure 1 is a schematic diagram of the structure of the multidimensional humidity and heat management fabric provided in the embodiment of this application. 1 is the basic pore type, and 2 is the functional pore type. Referring to Figure 1, the multidimensional humidity and heat management fabric has a layered structure with two or more layers and different hydrophilicities in the longitudinal direction. Based on improving the longitudinal moisture conduction by utilizing the interlayer effect of the fabric, a multi-level pore structure with different hydrophilicities is introduced in the transverse direction of the single-layer fabric.

[0011] The multi-level pore structure, connected to the outside world, consists of multiple basic pores 1 and multiple functional pores 2. The basic pores 1 are naturally formed between yarns after one or two yarns are interwoven into a fabric; they have small openings or pore diameters, are evenly distributed, and are relatively dense. The functional pores 2 are multiple openings or pores uniformly formed on the fabric surface using a special pore weaving process; compared to the basic pores 1, they have larger pore diameters and lower distribution density. Due to the differences in size and density of the basic pores 1 and functional pores 2, as well as the differences in the hydrophilicity of the surrounding yarns, a hydrostatic pressure difference is formed, generating a "wetting gradient effect" and a "differential capillary effect." Moisture is directionally conducted from the fabric substrate to the pores, causing moisture to accumulate around the functional pores 2. Through air convection in this area, moisture is more quickly wicked away and dissipated, resulting in excellent moisture absorption, quick drying, breathability, and rapid heat conduction properties of the fabric.

[0012] Specifically, the pore area of ​​each functional pore in the multidimensional heat and humidity management fabric is 1 mm². 2 -30mm2 5mm further 2 -22mm 2 For example, 6-8mm 2 10-15mm 2 or 16-20mm 2 The pore area of ​​each basic pore is 0.01 mm². 2 -0.9mm 2 In the embodiments of this application, the shapes of the basic pores and functional pores can be arbitrary, generally circular or approximately circular.

[0013] In this invention, the ratio of the total area of ​​the multiple functional pores of the multidimensional heat and humidity management fabric to the fabric area is no greater than 45%. At this ratio, there is sufficient fabric substrate to perform water absorption and moisture conduction, absorbing and transferring sweat to the pore area, while maintaining the opening area of ​​the pore area within a suitable range. This facilitates the formation of surface-fabric-environment convection, promoting the smooth and efficient removal of moisture to the external environment through evaporation. Specifically, the pore spacing in the length and width directions of each functional pore of the multidimensional heat and humidity management fabric is 0.1mm-25mm, more preferably 1-15mm, and more preferably 2mm, 3mm, 5mm, 10mm, etc.; the pore spacing in the length and width directions of each basic pore is 0.1mm-1mm.

[0014] The yarn fabrics surrounding the basic pores and functional pores described in this embodiment of the invention have their hydrophilic properties regulated by process parameters such as yarn material, yarn fineness, and fabric density. The hydrophilicity of the yarns surrounding each functional pore is higher than that surrounding each basic pore, forming a gradient for the directional transport of moisture from the basic pores to the functional pores. This promotes the accumulation of moisture around the functional pores, allowing for faster perspiration and heat dissipation through air convection in this area.

[0015] Specifically, the first and second yarns of the multidimensional moisture and heat management fabric are selected from cotton, linen, silk, wool, viscose fiber, polyester fiber, nylon fiber, or blends of these fibers. The first and second yarns can be made of different materials, resulting in different hydrophilicities; they can also be made of the same material, with variations in the weaving structure causing differences in the hydrophilicity of yarns around different pores. In some embodiments, to achieve environmental protection and sustainable development, natural fibers are preferred as raw materials, such as cellulose and protein fibers of different specifications and hydrophilicities. In other embodiments, polyester or its blends, which have low moisture absorption but fast drying properties, can be used. The multidimensional moisture and heat management fabric described in this invention has wide applicability, low requirements for fiber raw materials, and can optimize the moisture management performance of various fabrics.

[0016] More preferably, the first yarn can be selected from 30-60 count cellulose yarn materials, such as 40 count Xinjiang long-staple cotton; or from polyester yarn with a fineness of 40-100D. English count (Ne) – at standard moisture regain, a multiple of 840 yards in length of 1 pound of yarn. That is, 1 pound of yarn is exactly 840 yards long, which is 1 count yarn. 1 pound of yarn is 21 × 840 yards long, and the yarn fineness is 21 count, written as 21s. Denier (D) – also known as "denier," refers to the weight in grams of 9000 meters of yarn or fiber at standard moisture regain. It is a unit of length; the higher the weight, the coarser the yarn or fiber. It is often used to represent synthetic filaments, silk, etc. The standard moisture regain of cotton is generally 8.5%, while the standard moisture regain of polyester is usually around 0.4%.

[0017] Specifically, the multidimensional moisture management fabric has a double-layer longitudinal structure comprising an inner layer and an auxiliary layer, wherein the hydrophilicity of the auxiliary layer is greater than that of the inner layer. In some embodiments of the present invention, an auxiliary layer is added outside the inner layer fabric with a porous structure to form a multi-layered multidimensional moisture management fabric. The auxiliary layer has greater water absorption than the inner key layer fabric, improving the longitudinal moisture transfer efficiency between fabric layers. Compared to a single-layer fabric, the addition of the auxiliary layer creates a stagnant air layer between the fabric layers, which balances the convection formed in the porous areas, alleviating the instantaneous cooling sensation caused by rapid sweat evaporation, making it suitable for moisture management in lower temperature environments.

[0018] Specifically, the overall structure of the multidimensional heat and humidity management fabric is a combination of one or more of woven, knitted and nonwoven structures, and is more preferably a knitted structure; in some embodiments of the present invention, the overall structure of the fabric is a single-sided weft plain knitted structure or a double-sided weft knitted structure, wherein the functional pores can be formed directly by weaving or by laser cutting, needle punching and other methods.

[0019] Machine weaving (also known as shuttle weaving) creates different fabric patterns and structures by controlling the pattern of weft yarns passing through the warp yarns, including plain weave, twill weave, satin weave, and various complex weaves. Knitted fabrics are made by using knitting needles to form loops from yarns, which are then interlocked. They are divided into two main categories: weft knitting and warp knitting. Basic knitted structures include plain knit and rib knit. In weft knitted fabrics, each yarn forms a loop in one row of loops, with loops formed by a single yarn arranged along the weft direction of the fabric. In warp knitted fabrics, each yarn forms only one or two loops in each row of loops before moving to the next row to form more loops, with loops formed by a single yarn arranged along the warp direction of the fabric. Plain knit fabrics are knitted on a single-sided weft knitting machine; the yarns are sequentially bent into loops and passed from the wrong side of the old loop to the right side, forming a plain knit structure. Its two sides have different appearances. One side has V-shaped overlapping straight lines, that is, the side where the cylinder covers the arc is called the front side; the other side has arc-shaped overlapping lines, that is, the side where the arc covers the cylinder is called the back side.

[0020] Nonwoven structures, also known as nonwoven fabric structures, are defined in my country's national standard GB / T 5709-1997, "Textiles - Nonwoven Fabrics - Terminology," as: sheets, webs, or mats made of oriented or randomly arranged fibers bonded together by friction, cohesion, or adhesion, or a combination of these methods. This excludes paper, woven fabrics, knitted fabrics, tufted fabrics, and felt products produced by wet-spunbonding. Depending on the manufacturing process, nonwoven fabrics include spunlace, heat-sealed, and melt-blown types.

[0021] Referring to Figures 2 and 3, some embodiments of the multidimensional humidity and heat management fabric provided by the present invention have a knitted structure, on which basic pores (Figure 2) and functional pores (as shown in the middle of Figure 3) are uniformly distributed. The functional pores have a larger pore size and a lower distribution density than the basic pores. Referring to Figure 4, other embodiments of the present invention also provide a multidimensional humidity and heat management fabric with a knitted structure. In the embodiments of the present invention, the specific basis weight of the multidimensional humidity and heat management fabric is 130 g / m². 2 -230g / m 2 The transverse density is 8-18 threads / cm, and the longitudinal density is 8-15 threads / cm. The technology and finished product of this invention are environmentally friendly and sustainable. Based on the physical structure design of the fabric, this technology reduces the use of chemicals; it also improves heat and moisture conduction performance in multiple dimensions, including the longitudinal and transverse directions, and its performance is durable and unaffected by repeated use and washing. Furthermore, the fabric is soft and elastic, and will not adversely affect the feel. This ultra-breathable and lightweight textile structure of this invention has broad application prospects in the fields of sportswear, underwear, and other textiles.

[0022] A second aspect of the present invention provides a method for processing a multidimensional heat and humidity management fabric, the method comprising the following steps:

[0023] A multidimensional humidity and heat management fabric is obtained by using at least a first yarn and a second yarn with different hydrophilicity, and weaving them on a loom with a double-layer longitudinal structure and a transverse multi-level pore structure; the first yarn and the second yarn may be made of the same or different materials.

[0024] The multi-level pore structure includes multiple basic pores and multiple functional pores. The diameter of each functional pore is larger than that of each basic pore. The multiple functional pores are uniformly distributed around each basic pore, and their distribution density is lower than that of the basic pores. The ratio of the total area of ​​the multiple functional pores to the fabric area is no more than 45%. The hydrophilicity of the yarn surrounding each functional pore is higher than that of the yarn surrounding each basic pore.

[0025] In embodiments of the present invention, the design and configuration of the fabric substrate structure and density, functional pore structure, density and position are first implemented; and the pore fiber materials such as the first yarn and the second yarn are selected and rationally configured, and the yarn is spun and produced.

[0026] Specifically, in the design and configuration of the fabric substrate structure and density, functional pore structure, density and location, the pore area of ​​a single functional pore is 1-30 mm². 2 The pore area of ​​a single basic pore is 0.01-0.9 mm². 2 Furthermore, the ratio of the functional pore area to the total fabric area should not exceed 45%. In addition, the shapes of the basic pores and functional pores can be arbitrary; the pore spacing in the length and width directions of a single functional pore is preferably 0.1mm-25mm, and the pore spacing of a single basic pore is preferably 0.1mm-1mm.

[0027] Specifically, in the selection and reasonable configuration of the porous fiber materials such as the first yarn and the second yarn, pure natural / man-made or blended fiber materials can be used; preferably, they are selected from cotton, linen, silk, wool, viscose fiber, polyester fiber, nylon fiber or blended fibers of each fiber, as described above.

[0028] Specifically, the yarns for the first and second yarn materials can be produced using at least one of ring spinning, air-jet spinning, and jet spinning. Ring spinning is a mechanical spinning method where the yarn is twisted by a spindle, ring, and traveler, and then drafted by rollers; while air-jet spinning is a spinning method where the fiber is transported by airflow and twisted by holding it at one end. Preferably, the first yarn can be a 30-60 count cellulose yarn, such as 40 count Xinjiang long-staple cotton; or a polyester yarn with a fineness of 40-100D.

[0029] Specifically, the weaving on the machine is at least one of the following weaving methods: machine weaving, knitting, and non-woven weaving.

[0030] The greige fabric obtained through weaving in this embodiment of the invention is then dyed and / or finished to produce a multi-dimensional moisture and heat management fabric that is quick-drying, breathable, and rapidly conducts moisture and heat. The post-weaving processes in this embodiment include setting, dyeing, and finishing, all of which are conventional processes. Testing has shown that the fabric produced in this embodiment exhibits excellent moisture permeability, water evaporation, breathability, and thermal conductivity; its water absorption rate, wicking height, and evaporation rate all meet national standards.

[0031] Compared with existing technologies, the beneficial effects of the embodiments of this invention include: applying the technology of this invention to the production of moisture management fabrics significantly improves the heat and moisture conduction performance in multiple dimensions, including longitudinal and transverse directions; the performance is durable and unaffected by repeated use and washing; the fabric has good breathability and a soft hand feel. Simultaneously, the processing or preparation method of this invention has wide applicability, lower requirements for fiber raw materials, and can optimize the moisture management of fabrics in multiple dimensions. Furthermore, this invention simplifies the production process, integrating the functional design of the fabric into the conventional weaving process, eliminating the need for additional coating or hydrophilic finishing processes; it is environmentally friendly and sustainable, enabling large-scale production. The woven multidimensional moisture management fabrics can be used to manufacture underwear, work clothes, sportswear, and medical products, with particularly broad application prospects in outdoor sportswear and intimate apparel, providing the textile industry with more efficient, environmentally friendly, and multifunctional textiles to meet the needs of different fields.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Unless otherwise specified, all reagents and raw materials used in the present invention are commercially available products or products that can be prepared by recognized methods.

[0043] To better illustrate the present invention, further examples are provided below.

[0044] Example 1:

[0045] This embodiment provides a multidimensional humidity and heat management fabric and its processing method, the method including the following steps:

[0046] Step S1: Fabric base structure and density, design and configuration of functional pore structure, density and location; specifically, in this step, the fabric base structure adopts a single-sided weft plain knit structure, as shown in Figure 2. The functional pores are approximately circular, achieved using a perforation technique, as shown in Figure 3. The area of ​​a single functional pore is 7 mm². 2 The functional pore spacing is 5mm. The area of ​​a single basic pore is 0.55mm². 2 The basic pore spacing is 0.7mm.

[0047] Step S2: Selection and rational configuration of porous fibers; specifically, in this step, 40-count Xinjiang long-staple cotton is selected. Ring spinning is adopted.

[0048] Step S3: Weaving. In this step, the density of the knitted fabric is set, and then it is woven using a flat knitting machine to produce a multidimensional humidity and heat management fabric; Figure 5 shows a physical image of the multidimensional humidity and heat management fabric. The total area ratio of functional pores is 14%. The fabric has a warp density of 9 threads / cm, a weft density of 10 threads / cm, and a weight of 210g / m². 2 .

[0049] To test the performance of this multidimensional moisture and heat management fabric in terms of moisture and heat comfort, its water absorption rate, wicking height, and evaporation rate were tested according to the national standard test (GB / T 21655.1 Textiles - Evaluation of Moisture Absorption and Quick-Drying Properties - Part 1: Single-Item Combination Test Method). The test results are as follows:

[0050] Table 1: Results of Thermal Conductivity and Wetness Tests on Fabrics

[0051] As can be seen from the results in Table 1, the multidimensional moisture and heat management fabric has good air permeability and moisture and heat conduction properties; its water absorption rate, wicking height and evaporation rate all meet the national standard requirements (water absorption rate ≥200%, wicking height ≥100mm, evaporation rate ≥0.18g / h).

[0052] Example 2:

[0053] Using the same yarn and preparation process as in Example 1, Figure 6 shows the actual fabric obtained after weaving. The area of ​​a single functional pore is 19.6 mm². 2 The functional pore spacing is 3mm. The area of ​​a single basic pore is 0.55mm², and the spacing between basic pores is 0.7mm. Furthermore, the total area of ​​functional pores accounts for 30%. The fabric has a warp density of 9 threads / cm, a weft density of 10 threads / cm, and a weight of 210g / m². 2 Its performance tests are as follows:

[0054] Table 2: Results of Thermal Conductivity and Wetness Tests on Fabrics

[0055] Comparative Example 1:

[0056] Using yarns of the same specifications as in Examples 1 and 2, a non-functional porous fabric was prepared, with a functional pore area ratio of 0%. The fabric had a warp density of 9 threads / cm, a weft density of 10 threads / cm, and a weight of 215 g / m². 2 The performance is shown in Table 3, and a picture of the actual product is shown in Figure 7.

[0057] The results showed that the water absorption rate, air permeability, and evaporation rate of Examples 1 and 2 were all superior to those of Comparative Example 1. This indicates that the multidimensional moisture and heat management fabric provided in this embodiment has better air permeability and moisture wicking properties than ordinary non-functional porous fabrics. The fabric's air permeability and quick-drying properties are improved through the control of the fabric substrate and the properties of the functional pore materials (such as fibers and yarns), weaving methods, structure, and layer (layout) in its manufacturing process.

[0058] Table 3: Results of Thermal Conductivity and Wetness Tests on Fabrics

[0059] Example 3:

[0060] This embodiment provides a multidimensional humidity and heat management fabric and its processing method, the method including the following steps:

[0061] Step S1: Design and configuration of fabric substrate structure and density, functional pore structure, density, and location; specifically, in this step, the fabric substrate structure adopts a double-sided weft-knitted structure, and the circular functional pores are achieved through laser cutting. The area of ​​a single functional pore is 19.6 mm². 2 The functional pore spacing is 5mm. The area of ​​a single basic pore is 0.0123mm². 2 The basic pore spacing is 0.48 mm; the total area ratio of functional pores is 20%. The fabric has a warp density of 18 threads / cm, a weft density of 15 threads / cm, and a weight of 143 g / m². 2 .

[0062] Step S2: Selection and proper configuration of porous fibers; specifically, in this step, polyester fibers with low moisture absorption and fast drying are selected, with a yarn fineness of 100D / 36F. Step S3: Weaving on a circular knitting machine. In this step, the density of the knitted fabric is set, and then it is woven on a circular knitting machine.

[0063] Step S4: Pre-setting. In this step, the pre-setting temperature is 150-200℃, and the vehicle speed is 15-25m / min.

[0064] Step S5: Post-treatment. In this step, hydrophilic silicone oil is used for hydrophilic softening finishing at a temperature of 20-80℃ for 20-50 minutes. After treatment, it is dried at 80℃-95℃.

[0065] Step S6: Hole fabrication. In this step, holes are fabricated by laser cutting according to the designed functional pore area and functional pore spacing, thereby producing a multi-dimensional humidity and heat management fabric.

[0066] See Figure 8, which is a physical image of the multidimensional heat and humidity management fabric.

[0067] According to the national standard test (GB / T 21655.1 Evaluation of moisture absorption and quick-drying properties of textiles—Part 1: Single-item combination test method), its water absorption rate, wicking height, and evaporation rate were tested. The test results are as follows:

[0068] Table 4: Results of Thermal Conductivity and Wetness Tests on Fabrics

[0069] As can be seen from the results in Table 4, the multidimensional moisture and heat management fabric has good air permeability and moisture and heat conduction properties; its water absorption rate, wicking height and evaporation rate all meet the national standard requirements (water absorption rate ≥200%, wicking height ≥100mm, evaporation rate ≥0.18g / h).

[0070] Example 4:

[0071] The same yarn and preparation process were used as in Example 3. Figure 9 shows the actual woven product. The area of ​​a single functional pore is 7 mm². 2 The functional pore spacing is 3mm. The area of ​​a single basic pore is 0.0123mm². 2 The basic pore spacing is 0.48 mm. The total area of ​​functional pores accounts for 18%. The fabric has a warp density of 18 threads / cm, a weft density of 15 threads / cm, and a weight of 134 g / m². 2 .

[0072] Its performance tests are as follows:

[0073] Table 5: Results of Thermal Conductivity and Wetness Tests on Fabrics

[0074] Comparative Example 2:

[0075] Using yarns of the same specifications as in Examples 3 and 4, a non-functional porous fabric was prepared (see Figure 10 for the actual product), with a functional pore area ratio of 0%. The fabric has a warp density of 18 threads / cm, a weft density of 15 threads / cm, and a weight of 185 g / m². 2 The performance is shown in Table 6.

[0076] The results showed that the water absorption rate, air permeability, and evaporation rate of Examples 3 and 4 were all superior to those of the comparative example. This indicates that the multidimensional moisture management fabric provided in this embodiment has better air permeability and moisture wicking properties than ordinary non-functional porous fabrics.

[0077] Table 6: Results of Thermal Conductivity and Wetness Tests on Fabrics

[0078] Comparative Example 3:

[0079] Comparing the fabrics purchased from the market with other moisture-wicking and quick-drying products, the functional pore area ratio was 0%. The fabric's warp density is 16 threads / cm, its weft density is 24 threads / cm, and its weight is 195g / m². 2 The performance is shown in Table 7.

[0080] The results showed that the water absorption rate, air permeability, and evaporation rate of Examples 1, 2, 3, and 4 were all superior to those of Comparative Example 3. This indicates that the multidimensional moisture and heat management fabric provided in this embodiment has better air permeability and moisture wicking properties than commercially available quick-drying fabrics.

[0081] Table 7: Results of Thermal Conductivity and Wetness Tests on Fabrics

[0082] As can be seen from the above embodiments, the embodiments of the present invention, by designing the basic pores and functional pores of the fabric, and controlling the structure, distribution, and weaving methods of the basic pores and functional pores on the fabric, create differentiation between pores, thereby generating a surface energy gradient. This leads to asymmetry in pressure and water transport, enabling efficient conduction of moisture and heat in textiles, and providing a solution for the refined design of the thermal, moisture, and breathability management performance of textiles. The multidimensional heat and moisture management fabric developed by the present invention combines breathability, lightweight, and efficient heat and moisture management, with durable performance and soft fabric, and can be used to manufacture underwear, work clothes, sportswear, and medical products, etc.
