Description

Technical Field

[0001] This disclosure relates to a fabric, and more particularly to a temperature-sensitive humidity-regulating fabric. Background Technology

[0002] In recent years, as people's demands for quality of life have gradually increased, the comfort of clothing has become an important factor in purchasing clothing. Functional clothing that can adjust to temperature differences in autumn and winter, air-conditioned environments, and temperature and body temperature changes during exercise and sweating has emerged as a new product in today's textile market.

[0003] Textiles used in sportswear need to provide users with properties such as quick-drying, cooling sensation, and reduced heat loss to maintain thermal comfort when external environmental conditions change. However, traditional moisture-wicking clothing is mainly made through passive fabric structure design and finishing techniques (single-sided or double-sided coating). Therefore, under saturated humidity conditions during exercise, it has the disadvantage of losing its temperature and humidity regulation function due to stuffiness. Summary of the Invention

[0004] This disclosure provides a temperature-sensitive moisture-regulating fabric that has properties such as quick-drying, cooling sensation, and reduced heat loss, thereby providing stable thermal comfort.

[0005] According to some embodiments of this disclosure, a temperature-sensing and moisture-regulating fabric includes a plurality of temperature-sensing and moisture-regulating fibers. When the humidity is 65% and the temperature is between 20°C and 30°C, the temperature-moisture regain curve of the temperature-sensing and moisture-regulating fibers has a first slope; when the humidity is 65% and the temperature is between 30°C and 40°C, the temperature-moisture regain curve of the temperature-sensing and moisture-regulating fibers has a second slope, and the first slope is different from the second slope.

[0006] In some embodiments of this disclosure, the first slope is between -0.03% / ℃ and -0.04% / ℃, and the second slope is between -0.08% / ℃ and -0.09% / ℃.

[0007] In some embodiments of this disclosure, when the humidity is 90% and the temperature is between 20°C and 30°C, the temperature-moisture regain curve of the temperature-sensing and moisture-regulating fiber has a third slope, and when the humidity is 90% and the temperature is between 30°C and 40°C, the temperature-moisture regain curve of the temperature-sensing and moisture-regulating fiber has a fourth slope, and the third slope is different from the fourth slope.

[0008] In some embodiments of this disclosure, the third slope is between -0.05% / ℃ and -0.06% / ℃, and the fourth slope is between -0.09% / ℃ and -0.10% / ℃.

[0009] In some embodiments of this disclosure, the temperature-sensitive humidity-regulating fabric is a double-sided mesh knitted fabric.

[0010] In some embodiments of this disclosure, the temperature-sensitive humidity-regulating fabric is a single-sided horizontal striped knit fabric.

[0011] In some embodiments of this disclosure, the temperature-sensitive humidity-regulating fabric is a layered knitted fabric.

[0012] In some embodiments of this disclosure, the temperature-sensitive humidity-regulating fabric is a single-sided horizontal striped checkered knit fabric.

[0013] In some embodiments of this disclosure, the temperature-sensitive humidity-regulating fiber includes a hydrophilic material and a temperature-sensitive material. The weight ratio of the hydrophilic material to the temperature-sensitive material is between 3:7 and 7:3, and the temperature-sensitive material has a lower critical solution temperature (LCST) between 31.2°C and 32.5°C when the light transmittance is between 3% and 80%, wherein the wavelength of the light is between 450 nm and 550 nm.

[0014] In some embodiments of this disclosure, the temperature-sensing material comprises a structure represented by formula (1):

[0015] Equation (1), wherein in Equation (1), X includes a structure represented by Equation (2) or Equation (3):

[0016] Equation (2),

[0017] Equation (3), where the molar ratio of x to y is between 9:1 and 1:3, n is an integer between 7 and 120, and m is an integer between 10 and 1000.

[0018] According to the above embodiments of this disclosure, the temperature-sensing and moisture-regulating fabric of this disclosure includes multiple temperature-sensing and moisture-regulating fibers. Since the temperature-sensing and moisture-regulating fibers have a temperature-moisture regain change curve with an inflection point under specific humidity conditions, the temperature-sensing and moisture-regulating fabric can dry quickly at high temperatures to achieve a cooling function, while at low temperatures it can slow down the drying rate of moisture to reduce heat loss, thereby maintaining the user's body temperature and providing stable thermal comfort.

[0027] B: Exercise period

[0028] C: Recovery period Detailed Implementation

[0029] Several embodiments of this disclosure will be disclosed below. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this disclosure. That is, in some embodiments of this disclosure, these practical details are not essential and therefore should not be used to limit this disclosure.

[0030] In this article, the structure of polymers or groups is sometimes represented by a skeleton formula. This representation may omit carbon atoms, hydrogen atoms, and carbon-hydrogen bonds. Of course, if the structural formula explicitly shows atoms or atomic groups, the formula shown shall prevail.

[0031] This disclosure provides a temperature-regulating fabric comprising multiple temperature-regulating fibers. Because the temperature-regulating fibers exhibit a temperature-moisture regain change curve with a turning point at specific humidity levels, the temperature-regulating fabric of this disclosure can dry rapidly at high temperatures to achieve a cooling function, while at low temperatures it can slow down the drying rate to reduce heat loss, thereby maintaining the user's body temperature and providing stable thermal comfort.

[0032] Please see Figure 1 It shows temperature-moisture regain variation curves of temperature-sensing and moisture-regulating fibers in temperature-sensing and moisture-regulating fabrics according to some embodiments of the present disclosure, and of conventional polyester fibers in conventional polyester fabrics of comparative examples. Specifically, Figure 1The display shows the temperature-moisture regain curves of temperature-sensitive moisture-regulating fibers and conventional polyester fibers as the ambient temperature is gradually increased from 20°C to 40°C at a humidity of 65%. Figure 1 It can be seen that when the humidity is 65% and the temperature is between 20℃ and 30℃, the temperature-moisture regain curve of the temperature-sensing and moisture-regulating fiber has a first slope, while when the humidity is 65% and the temperature is between 30℃ and 40℃, the temperature-moisture regain curve has a second slope, and the first slope is different from the second slope. In other words, the temperature-moisture regain curve of the temperature-sensing and moisture-regulating fiber has a turning point P at a temperature of 30℃. Through the design of this turning point P, the temperature-sensing and moisture-regulating fiber can have different hydrophilicity at temperatures between 20℃ and 30℃ and between 30℃ and 40℃, thereby enabling the temperature-sensing and moisture-regulating fabric made from it to have the function of sensing and regulating humidity.

[0033] In some embodiments, the absolute value of the first slope may be less than the absolute value of the second slope. Thus, at relatively low temperatures, the temperature-regulating fiber may have strong hydrophilicity, while at relatively high temperatures, it may have weak hydrophilicity. Consequently, temperature-regulating fabrics made from this fiber can dry rapidly at high temperatures to achieve a cooling function, and at low temperatures, the drying rate can be slowed to reduce heat loss. In some embodiments, the first slope may be between -0.03% / ℃ and -0.04% / ℃ (e.g., -0.0311), and the second slope may be between -0.08% / ℃ and -0.09% / ℃ (e.g., -0.0844), thereby better achieving the above functions and providing users with stable thermal comfort, making it suitable for various moisture-wicking products.

[0034] Please see Figure 2 It shows temperature-moisture regain variation curves of temperature-sensing and moisture-regulating fibers in temperature-sensing and moisture-regulating fabrics according to some embodiments of the present disclosure, and of conventional polyester fibers in conventional polyester fabrics of comparative examples. Specifically, Figure 2 The display shows the temperature-moisture regain curves of temperature-sensitive moisture-regulating fibers and conventional polyester fibers as the ambient temperature is gradually increased from 20℃ to 40℃ at a humidity of 90%. Figure 2It can be seen that when the humidity is 90% and the temperature is between 20℃ and 30℃, the temperature-moisture regain curve of the temperature-sensing and moisture-regulating fiber can be calculated to have a third slope. When the humidity is 90% and the temperature is between 30℃ and 40℃, the temperature-moisture regain curve of the temperature-sensing and moisture-regulating fiber can be calculated to have a fourth slope, and the third slope may differ from the fourth slope. In other words, the temperature-moisture regain curve of the temperature-sensing and moisture-regulating fiber has a turning point P at 30℃. Through the design of this turning point P, the temperature-sensing and moisture-regulating fiber can exhibit different hydrophilicities at temperatures between 20℃ and 30℃ and between 30℃ and 40℃, thereby enabling the temperature-sensing and moisture-regulating fabric made from it to possess temperature-sensing and moisture-regulating functions.

[0035] In some embodiments, the absolute value of the third slope may be less than the absolute value of the fourth slope. Thus, at relatively low temperatures, the temperature-regulating fiber may have strong hydrophilicity, while at relatively high temperatures, it may have weak hydrophilicity. Consequently, temperature-regulating fabrics made from this fiber can dry rapidly at high temperatures to achieve a cooling function, and at low temperatures, the drying rate can be slowed to reduce heat loss. In some embodiments, the third slope may be between -0.05% / ℃ and -0.06% / ℃ (e.g., -0.0526), ​​and the fourth slope may be between -0.09% / ℃ and -0.10% / ℃ (e.g., -0.0965), thereby better achieving the above functions and providing users with stable thermal comfort, making it well-suited for various moisture-wicking products.

[0036] Overall Figure 1 and Figure 2 It is known that, regardless of whether the environment is relatively low humidity (e.g., 65%) or relatively high humidity (e.g., 90%), the temperature-moisture regain curve of the temperature-sensing and moisture-regulating fiber exhibits an inflection point P at 30°C. Therefore, the temperature-sensing and moisture-regulating fabric can possess good temperature-sensing and moisture-regulating functions within a general range of ambient humidity. Furthermore, regardless of whether the environment is relatively low or relatively high humidity, compared to conventional polyester fibers, the temperature-sensing and moisture-regulating fibers in the disclosed temperature-sensing and moisture-regulating fabric not only all exhibit a clear inflection point P (conventional polyester fibers do not show a clear inflection point), but also have a higher moisture regain, making them suitable for various products requiring moisture-wicking and perspiration-absorbing functions.

[0037] It should be further noted that the method for measuring moisture regain in this disclosure involves placing fabrics (e.g., temperature-sensitive moisture-regulating fabrics, conventional polyester fabrics) in different environments to obtain fabric weights W1 to W2, and then calculating the moisture regain of each fabric based on its weights W1 to W2. For example, in Figure 1In this context, W1 represents the fabric weight measured in an absolutely dry environment (105 degrees Celsius, 0% RH, for 2 hours), and W2 represents the fabric weight measured in a high-humidity environment (20, 25, 30, 35, and 40 degrees Celsius, 65% RH, for 24 hours). As another example, in... Figure 2 In the figure, W1 is the fabric weight measured in an absolutely dry environment (105 degrees Celsius, 0% RH, for 2 hours), while W2 is the fabric weight measured in a high humidity environment (20, 25, 30, 35 and 40 degrees Celsius, 90% RH, for 24 hours).

[0038] In some embodiments, the temperature-sensitive humidity-regulating fiber may include a hydrophilic material and a temperature-sensitive material. In some embodiments, the hydrophilic material may include a structure represented by formula (I):

[0039] Equation (I) is used, where the molar ratio of x to y is between 9:1 and 1:3, n is an integer between 7 and 120, and m is an integer between 10 and 1000. By adjusting the molar ratio of x to y and the values ​​of m and n, the compatibility of the hydrophilic material with other polyester materials in the temperature-sensitive humidity-regulating fiber can be significantly improved, giving the temperature-sensitive humidity-regulating fiber good and stable hydrophilicity, thereby enhancing the moisture conductivity of the temperature-sensitive humidity-regulating fiber and facilitating moisture regulation and evaporation.

[0040] In some embodiments, the temperature-sensing material may include a structure represented by formula (1):

[0041] Equation (1), wherein in Equation (1), X includes a structure represented by Equation (2) or Equation (3):

[0042] Equation (2),

[0043] Equation (3), where the molar ratio of x to y is between 9:1 and 1:3, n is an integer between 7 and 120, and m is an integer between 10 and 1000. In some embodiments, the weight-average molecular weight of the temperature-sensitive material can be between 10,000 and 150,000. By adjusting the above-mentioned molar ratio of x to y, the values ​​of m and n, and the range of weight-average molecular weight, the compatibility of the temperature-sensitive material with other polyester materials in the temperature-sensitive humidity-regulating fiber can be greatly improved, enabling the temperature-sensitive humidity-regulating fiber to effectively change with the ambient temperature or body temperature, thereby dynamically regulating temperature and humidity.

[0044] In some embodiments, the thermosensitive material can have different light transmittance at different temperatures. Specifically, the thermosensitive material has high light transmittance at relatively low temperatures (e.g., 31.0°C) and low light transmittance at relatively high temperatures (e.g., 33.0°C). These characteristics of the thermosensitive material can be specifically demonstrated by its lower critical solution temperature (LCST). Specifically, as the temperature rises, the thermosensitive material aggregates, causing a decrease in light transmittance. When the light transmittance decreases to 3%, the degree of aggregation of the thermosensitive material hardly changes with further temperature increases; this temperature represents the maximum value of the LCST. Conversely, as the temperature decreases, the thermosensitive material disperses, causing an increase in light transmittance. When the light transmittance increases to 80%, the degree of dispersion of the thermosensitive material hardly changes with further temperature decreases; this temperature represents the minimum value of the LCST. Specifically, the temperature-sensitive material possesses a low critical solution temperature between 31.2°C and 32.5°C when its light transmittance is between 3% and 80%, with the wavelength of the light between 450nm and 550nm. By equipping the temperature-sensitive material with a suitable low critical solution temperature, it can exhibit different degrees of hydrophilicity at different temperatures. Specifically, the temperature-sensitive material exhibits strong hydrophilicity at relatively low temperatures and weak hydrophilicity at relatively high temperatures. This allows temperature-sensitive moisture-regulating fibers and fabrics made from them to dry rapidly at high temperatures, achieving a cooling function, and at low temperatures, to slow down the drying rate, thereby reducing heat loss. It is worth noting that, as mentioned above... Figure 1 and Figure 2 It can be seen that, Figure 1 and Figure 2 The temperature of the inflection point P (30℃) falls precisely near the low critical solution temperature (31.2℃ to 32.5℃) of the temperature-sensitive material. This shows that the temperature-sensitive material can effectively perform its function in the temperature-sensitive humidity-regulating fiber without being affected by the hydrophilic material, thus enabling the temperature-sensitive humidity-regulating fiber and the temperature-sensitive humidity-regulating fabric made from it to have the function of temperature-sensitive humidity regulation.

[0045] In some embodiments, when a thermosensitive material is mixed with a hydrophilic material to form a thermosensitive humidity-regulating material, the light transmittance of the thermosensitive humidity-regulating material can change with temperature. Specifically, the thermosensitive humidity-regulating material exhibits high light transmittance at relatively low temperatures (e.g., 31.0°C) and low light transmittance at relatively high temperatures (e.g., 37.0°C). These characteristics of the thermosensitive humidity-regulating material can be specifically manifested through a low critical solution temperature. For example, when a hydrophilic material and a thermosensitive material are uniformly mixed in a 3:7 weight ratio to form a thermosensitive humidity-regulating material, the material has a low critical solution temperature between 31.2°C and 33.5°C when the light transmittance is between 3% and 80%. For example, when a hydrophilic material and a thermosensitive material are uniformly mixed in a 1:1 weight ratio to form a temperature-sensitive humidity-regulating material, the material has a low critical solution temperature between 31.2°C and 34.5°C when the light transmittance is between 3% and 80%. As another example, when a hydrophilic material and a thermosensitive material are uniformly mixed in a 7:3 weight ratio to form a temperature-sensitive humidity-regulating material, the material has a low critical solution temperature between 31.2°C and 36.0°C when the light transmittance is between 3% and 80%. Based on the above, when the thermosensitive material and the hydrophilic material of this disclosure are uniformly mixed in an appropriate weight ratio, the resulting temperature-sensitive humidity-regulating material can have a suitable temperature close to the low critical solution temperature of the thermosensitive material. In other words, the thermosensitive material can effectively perform its function in the temperature-sensitive humidity-regulating fiber without being affected by the hydrophilic material, enabling the temperature-sensitive humidity-regulating fiber and the temperature-sensitive humidity-regulating fabric made therefrom to possess temperature-sensitive humidity-regulating functions. Therefore, the weight ratio of hydrophilic material to thermosensitive material can be between 3:7 and 7:3, thereby providing the thermosensitive moisture-regulating fiber with good moisture wicking properties and the ability to dynamically regulate temperature and humidity. Specifically, if the weight ratio is less than 3:7 (e.g., 2:8), the thermosensitive moisture-regulating fiber is prone to insufficient hydrophilicity, thus affecting its moisture wicking properties and water evaporation rate. Furthermore, an excessively high proportion of thermosensitive material can lead to overly complex processing (as the processing steps for thermosensitive material are more complex than those for hydrophilic material). Conversely, if the weight ratio is greater than 7:3 (e.g., 8:2), the thermosensitive moisture-regulating fiber's ability to regulate temperature and humidity is insufficient, thus affecting the thermosensitive moisture-regulating properties of the fabric made from it.

[0046] To clarify, the method for measuring the lower critical solution temperature of the temperature-sensitive material (or temperature-sensitive humidity-regulating material) includes the following steps: First, at room temperature, place 4 mL of the temperature-sensitive material (or temperature-sensitive humidity-regulating material) into a 5 mL sample vial. Next, place the sample vial into a UV / Vis spectrophotometer (model: JASCO V630). Then, set the initial temperature of the UV / Vis spectrophotometer to 25°C and begin measurement. Next, gradually increase the temperature to 36.5°C at a heating rate of 1°C / min, and record the light transmittance of the temperature-sensitive material (or temperature-sensitive humidity-regulating material) at each temperature. After the above steps, the lower critical solution temperature of the temperature-sensitive material (or temperature-sensitive humidity-regulating material) can be obtained.

[0047] In some embodiments, the temperature-sensing and humidity-regulating function of the fabric can be further optimized by adjusting the weave design and yarn ratio. In other words, through various weave designs and yarn ratios, the temperature-sensing and humidity-regulating fabric can have different drying rates, thus possessing wide applicability. Specifically, the temperature-sensing and humidity-regulating fabric of this disclosure can, for example, be woven using a circular knitting machine, and this disclosure uses multiple weave diagrams to represent various weave designs of the temperature-sensing and humidity-regulating fabric. More specifically, please refer to... Figures 3A to 3D It shows weave diagrams of temperature-sensitive humidity-regulating fabrics according to different embodiments of the present disclosure.

[0048] To elaborate, Figure 3A The temperature-sensitive moisture-regulating fabric woven using the weave pattern in Figure 3B is a double-sided mesh knit fabric; the temperature-sensitive moisture-regulating fabric woven using the weave pattern in Figure 3C is a single-sided horizontal stripe knit fabric; and the temperature-sensitive moisture-regulating fabric woven using the weave pattern in Figure 3C is a layered yarn knit fabric. Figure 3D The temperature-sensitive and humidity-regulating fabric woven according to the weave pattern is a single-sided horizontal striped checkered knitted fabric. It should be understood that in Figures 3A to 3D, the symbol "T" represents polyester fiber (e.g., PET fiber or PET yarn), the symbol "S" represents temperature-sensitive and humidity-regulating fiber, the symbol "T / OP" represents polyester fiber (e.g., PET fiber or PET yarn) covered with polyurethane elastic fiber, the symbol "S / OP" represents temperature-sensitive and humidity-regulating fiber covered with polyurethane elastic fiber, and the symbol "C / OP" represents cationic dyeable polyester fiber covered with polyurethane elastic fiber.

[0049] In the following description, various tests will be conducted on the temperature-sensitive and moisture-regulating fabric of this disclosure to further verify the effectiveness of this disclosure. It should be understood that this disclosure should not be interpreted as limiting by the embodiments described below.

[0050] <Experiment Example 1: Human Sweating Trunk Thermal Moisture Comfort Test>

[0051] In this experimental example, the thermo-humidity regulating fabric of Example 1 and the fabric of Comparative Example 1 were tested for human thermal comfort under sweating using the international standard method ISO 18640-1 and the Thermal Comfort Instrument for Sweaty Torso (TORSO). The thermo-humidity regulating fabric of Example 1 is a single-sided plain weave fabric woven from thermo-humidity regulating fibers, while the fabric of Comparative Example 1 is a single-sided plain weave fabric woven from conventional PET fibers. The test results are as follows: Figure 4A and Figure 4B As shown, where Figure 4A The diagram shows the weight versus time relationship of the temperature-sensitive humidity-regulating fabric of Example 1 and the fabric of Comparative Example 1, while... Figure 4B The temperature versus time graphs of the temperature-sensitive humidity-regulating fabric of Example 1 and the fabric of Comparative Example 1 are shown.

[0052] Depend on Figure 4A It can be seen that the temperature-regulating fabric of Example 1 and Comparative Example 1 showed almost no difference in performance during the adaptation period A and recovery period C. However, during the exercise period B (i.e., the period when sweating is greater than 100g / hr), the weight of the fabric of Comparative Example 1 increased rapidly, while the weight of the temperature-regulating fabric of Example 1 increased only slightly. This indicates that sweat does not accumulate in large quantities on the temperature-regulating fabric of Example 1; that is, the evaporation rate of sweat on the temperature-regulating fabric of Example 1 is significantly faster, allowing for rapid drying at high temperatures to achieve a cooling function. On the other hand, due to... Figure 4B It can be seen that the temperature-sensitive moisture-regulating fabric of Example 1 drops significantly during the exercise period B, indicating that it can dry quickly at high temperatures to achieve a cooling function. Furthermore, the temperature rises significantly during the recovery period C, indicating that it can slow down the drying rate of moisture at low temperatures to reduce heat loss and effectively prevent chills.

[0053] <Experiment Example 2: Fabric Drying Time Test>

[0054] In this experimental example, the drying time of the fabrics in the comparative examples and the temperature-sensitive humidity-regulating fabrics in the embodiments was tested using a slightly modified AATCC-199 standard method. The test conditions in this experimental example were: temperature 20°C, humidity 65%, heating plate temperature 35°C, and water volume 0.1 mL. Detailed descriptions of each comparative example and embodiment are shown in Table 1, and the test results are shown in Table 2.

[0055] Table 1

[0056]

[0057] Table 2

[0058]

[0059] As shown in Table 2, compared to Comparative Example 2, the drying time of Example 2 was shortened by approximately 15.53%; compared to Comparative Example 3, the drying time of Example 3 was shortened by approximately 15.89%; and compared to Comparative Example 4, the drying time of Example 4 was shortened by approximately 11.57%, demonstrating that the temperature-sensitive moisture-regulating fabric of this disclosure has a better drying effect. Furthermore, Example 5 also had a short drying time and good drying effect.

[0060] <Experiment Example 3: Fabric Moisture Drying Rate Test>

[0061] In this experimental example, the moisture drying rate of the fabrics in Comparative Examples 2-4 and the temperature-sensitive humidity-regulating fabrics in Examples 2-4 was tested under different temperature and humidity conditions. In this experimental example, the moisture drying rate test method was as follows: water was dripped onto the fabric surface, the initial weight of the fabric was recorded after the water was dripped, and the weight of the fabric was recorded at fixed intervals to calculate the moisture evaporation rate. The test conditions were: fabric area 5x5cm. 2 The water volume was 0.2 mL. The test results are shown in Table 3.

[0062] Table 3

[0063]

[0064] As shown in Table 3, compared to the fabrics of the comparative examples, the temperature-sensitive humidity-regulating fabrics of each embodiment can dry more quickly at both high and low temperatures. On the other hand, the moisture on the temperature-sensitive humidity-regulating fabrics of each embodiment does not evaporate too quickly at low temperatures. Therefore, the temperature-sensitive humidity-regulating fabric of this disclosure can dry quickly to achieve a cooling function, and can appropriately reduce heat loss at low temperatures.

[0065] According to the embodiments described above, the temperature-regulating fabric of this disclosure includes multiple temperature-regulating fibers. Because the temperature-regulating fibers have a temperature-moisture regain change curve with a turning point at a specific humidity level, the temperature-regulating fabric can dry quickly at high temperatures to achieve a cooling function, while at low temperatures it can slow down the drying rate to reduce heat loss, thereby maintaining the user's body temperature and providing stable thermal comfort. Furthermore, through the weave design and yarn ratio of the temperature-regulating fabric, its temperature-regulating function can be optimized for wide application in various moisture-wicking products.

[0066] Although this disclosure has been described above with reference to embodiments, it is not intended to limit this disclosure. Any person skilled in the art can make various modifications and refinements without departing from the spirit and scope of this disclosure. Therefore, the scope of protection of this disclosure shall be determined by the appended claims.
