BRIEF DESCRIPTION OF THE DRAWINGS

[0016] none DETAILED DESCRIPTION

[0017] The following will disclose a number of embodiments of the present disclosure. For the purpose of clarity, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present disclosure. In other words, in some embodiments of the present disclosure, these practical details are not necessary and therefore should not be used to limit the present disclosure.

[0018] The present disclosure provides a method for making a heat-resistant and UV-resistant fabric. The heat-resistant and UV-resistant fabric is prepared using raw materials. By allowing the raw materials to contain an appropriate amount of near-infrared reflective dye, not only can a fabric with heat-resistant and UV-resistant properties be obtained, but the fabric can also be suitable for being given a dark color through post-processing dyeing. Compared with the traditional use of titanium dioxide-based additives to make fabrics have UV resistance, the present disclosure uses near-infrared reflective dyes to make fabrics have UV resistance and can make the fabrics have a dark color through dyeing, which helps to improve the convenience of making dark fabrics and meet economic costs. The heat-resistant and UV-resistant fabric disclosed in the present disclosure can be used in textiles for high-exposure outdoor activities such as parasols, tents, awnings, coats, and hats.

[0019] The method for making the heat-resistant and UV-resistant fabric disclosed herein includes steps S10-S30. In step S10, the raw material is melt-spun to form a plurality of fibers, so that the fibers contain an appropriate amount of near-infrared reflective dye. In step S20, the fibers are woven to form the heat-resistant and UV-resistant fabric. In step S30, the heat-resistant and UV-resistant fabric is post-processed and dyed. In the following description, each of the above steps will be described in detail.

[0020] Before performing step S10, a raw material containing a near-infrared reflective masterbatch (also referred to as the first raw material in this article) may be prepared. In detail, the first raw material includes a near-infrared reflective masterbatch, and the near-infrared reflective masterbatch includes a near-infrared reflective dye. By adding a near-infrared reflective dye, the fiber and fabric prepared from the near-infrared reflective masterbatch can not only have near-infrared reflection (heat resistance) performance, but also have anti-ultraviolet performance. In some embodiments, the near-infrared reflective dye may be a titanium antimony nickel yellow dye, such as V-9415 (commodity model, purchased from Ferro). Titanium antimony nickel yellow dye not only has a good near-infrared reflection function, but also has a light color and is less likely to affect the effect of subsequent dyeing. In some embodiments, the near-infrared reflective masterbatch may further include a carrier. In detail, the carrier may be polyester (e.g., polyethylene terephthalate, polybutylene terephthalate, or a combination thereof) or nylon (e.g., nylon 6). In a preferred embodiment, the carrier may be nylon, which is suitable for acid dyeing process, so that the near-infrared reflective dye can be selected as titanium antimony nickel yellow dye.

[0021] In some embodiments, 72 to 89 parts by weight of the carrier and 10 to 25 parts by weight of the near-infrared reflective dye may be mixed and granulated to form a near-infrared reflective masterbatch. For example, the content of the carrier may be 74 parts by weight, 76 parts by weight, 78 parts by weight, 80 parts by weight, 82 parts by weight, 84 parts by weight, 86 parts by weight, or 88 parts by weight, and the content of the near-infrared reflective dye may be 11 parts by weight, 12 parts by weight, 14 parts by weight, 16 parts by weight, 18 parts by weight, 20 parts by weight, 22 parts by weight, or 24 parts by weight. In detail, if the content of the carrier is too high and the content of the near-infrared reflective dye is too low, the fiber and fabric may only have near-infrared reflective (heat-blocking) properties but lack sufficient UV resistance; if the content of the carrier is too low and the content of the near-infrared reflective dye is too high, the fabric may not be able to achieve a deep dyeing effect through a post-processing dyeing process. In some embodiments, a dispersant may be further added during mixing and granulation to improve the dispersibility of each component. It has been verified that when a dispersant is added, the pressure rise test is performed with a filter with a pore size of 40 microns, and the result shows that it is less than 10 bar / kg, which meets the process requirements. In detail, the dispersant can be EMS-Griltex D1556A (trade model, purchased from EMS-Griltech), and its content can be 1 to 3 parts by weight. In some embodiments, a twin-screw extruder can be used for the mixing and granulation process, wherein the screw speed can be 240 rpm to 260 rpm, and the mixing temperature can be 240° C. to 260° C.

[0022] In other embodiments, before performing step S10, a raw material containing both near-infrared reflective masterbatch and anti-ultraviolet masterbatch (also referred to as the second raw material in this article) may also be prepared. In detail, in this embodiment, the second raw material includes near-infrared reflective masterbatch and anti-ultraviolet masterbatch, wherein the near-infrared reflective masterbatch includes the aforementioned near-infrared reflective dye, and the anti-ultraviolet masterbatch may include titanium dioxide. By further adding titanium dioxide, the fibers and fabrics prepared from the second raw material may have better anti-ultraviolet properties. In some embodiments, titanium dioxide may be TITANIUMDIOXIDE (trade model, purchased from Dingxin Company). In some embodiments, the anti-ultraviolet masterbatch may further include a carrier. In detail, the carrier may be polyester (e.g., polyethylene terephthalate, polybutylene terephthalate, or a combination thereof) or nylon (e.g., nylon 6). In a preferred embodiment, the carrier in the anti-UV masterbatch and the carrier in the near-infrared reflecting masterbatch are both nylon, thereby improving the compatibility of the anti-UV masterbatch and the near-infrared reflecting masterbatch, and making the subsequently produced fibers have material homogeneity, thereby improving the applicability, dyeing uniformity and recyclability of the fibers.

[0023] In some embodiments, 72 to 89 parts by weight of the carrier and 10 to 25 parts by weight of titanium dioxide can be mixed and granulated to form an anti-ultraviolet masterbatch. For example, the content of the carrier can be 74 parts by weight, 76 parts by weight, 78 parts by weight, 80 parts by weight, 82 parts by weight, 84 parts by weight, 86 parts by weight or 88 parts by weight, and the content of titanium dioxide can be 12 parts by weight, 14 parts by weight, 16 parts by weight, 18 parts by weight, 20 parts by weight, 22 parts by weight or 24 parts by weight. If the content of the carrier is too high and the content of titanium dioxide is too low, the fiber and fabric may not provide better anti-ultraviolet performance; if the content of the carrier is too low and the content of titanium dioxide is too high, the titanium dioxide molecules are easy to fill the gaps in the fabric, making it difficult for the colorant to be effectively embedded in the fabric, thereby causing the fabric to be unable to achieve a dark dyeing effect through post-processing dyeing. In some embodiments, a dispersant can be further added during the mixing and granulation to improve the dispersibility of each component. It has been verified that when a dispersant is added, the pressure rise test is performed with a filter with a pore size of 40 microns, and the result shows that it is less than 10 bar / kg, which meets the process requirements. In detail, the dispersant can be, for example, EMS-Griltex D1556A (trade model, purchased from EMS-Griltech), and its content can be 1 to 3 parts by weight. In some embodiments, a twin-screw extruder can be used for the mixing and granulation process, wherein the screw speed can be 240 rpm to 260 rpm, and the mixing temperature can be 240° C. to 260° C.

[0024] After completing the above steps, a first raw material containing near-infrared reflective masterbatch and a second raw material containing both near-infrared reflective masterbatch and anti-ultraviolet masterbatch can be obtained. Subsequently, subsequent steps can be performed to further obtain fibers made of the first raw material or the second raw material and heat-resistant and anti-ultraviolet fabrics.

[0025] In step S10, the first raw material is melt-spun to form a plurality of fibers, wherein the first raw material includes a near-infrared reflective masterbatch, and the near-infrared reflective masterbatch includes a near-infrared reflective dye. In other words, the present disclosure forms a plurality of fibers by melt-spinning a masterbatch containing a near-infrared reflective dye. During melt spinning, the proportion of the near-infrared reflective dye in the fiber can be adjusted by adding a base material powder such as polyester (polyethylene terephthalate, polybutylene terephthalate, or a combination thereof) or nylon (nylon 6). In detail, when the sum of the plurality of fibers is 100 weight percent (wt%), the near-infrared reflective dye in the plurality of fibers is 0.5 weight percent to 1.0 weight percent (e.g., 0.6wt%, 0.7wt%, 0.8wt%, 0.9wt%). By controlling the proportion of near-infrared reflective dyes in the fiber, the fiber and the fabric subsequently produced can have both heat-resistant and UV-resistant properties, and can ensure that the fabric is suitable for being given a dark color through post-processing dyeing. In detail, if the proportion of near-infrared reflective dyes in the fiber is less than 0.5 weight percent, the fiber and fabric may only have near-infrared reflective (heat-resistant) properties but lack sufficient UV resistance; if the proportion of near-infrared reflective dyes in the fiber is greater than 1.0 weight percent, the fabric may not be able to achieve a dark dyeing effect through post-processing dyeing.

[0026] In some other embodiments of step S10, the second raw material may be melt-spun, wherein the second raw material includes a near-infrared reflective masterbatch and an anti-ultraviolet masterbatch, the near-infrared reflective masterbatch includes an infrared reflective dye, and the anti-ultraviolet masterbatch includes titanium dioxide. In other words, a plurality of fibers may be formed by melt-spinning the uniformly mixed near-infrared reflective masterbatch and the anti-ultraviolet masterbatch. Similarly, during melt spinning, the proportion of the near-infrared reflective dye and titanium dioxide in the fiber may be adjusted by adding a base material powder such as polyester (polyethylene terephthalate, polybutylene terephthalate, or a combination thereof) or nylon (nylon 6). In detail, when the sum of the multiple fibers is 100 weight percent (wt%), the near-infrared reflective dye in the multiple fibers is 0.5 weight percent to 1.0 weight percent (e.g., 0.6wt%, 0.7wt%, 0.8wt%, 0.9wt%), and the titanium dioxide in the multiple fibers is 0.4 weight percent to 0.6 weight percent (e.g., 0.45wt%, 0.50wt%, 0.55wt%). By controlling the proportion of titanium dioxide in the fiber, the fiber and the subsequent fabric produced can have better performance in terms of UV resistance, and can ensure that the fabric is suitable for being given a dark color through post-processing dyeing. In detail, if the proportion of titanium dioxide in the fiber is less than 0.4 weight percent, the effect of further improving the UV resistance of the fiber is limited; if the proportion of titanium dioxide in the fiber is greater than 0.6 weight percent, it may cause the fabric to be unable to achieve a dark dyeing effect through post-processing dyeing.

[0027] In some embodiments, the spinning temperature of the melt spinning process may be 250°C to 270°C, and the spinning speed of the melt spinning process may be 3000 m / min to 3500 m / min. In some embodiments, the fiber obtained by melt spinning may be a single-component fiber, that is, the near-infrared reflective dye (and titanium dioxide) may be evenly dispersed in a carrier and a substrate powder of a single material. By designing the fiber to be a single-component type, the distribution of the near-infrared reflective dye and titanium dioxide in a single fiber may be more even, so that the fiber may have similar heat resistance and UV resistance performance on any surface, and no matter how it is woven subsequently, it will not affect the performance of heat resistance and UV resistance, and it may also be conducive to recycling and environmental protection. On the other hand, compared with composite fibers, single-component fibers can overcome the problem of uneven dyeing and achieve excellent uniform dyeing effects. In a preferred embodiment, the base material (e.g., the material of the carrier and the substrate powder) in the single-component fiber may be nylon 6.

[0028] In some embodiments, the fiber produced by melt spinning may have a fiber specification of 39 denier to 41 denier. In detail, since the current market trend is for sports and outdoor products to be refined and lightweight, the formation of fine denier with the above fiber specifications helps to meet the current market demand. On the other hand, since the near-infrared reflective dye and titanium dioxide disclosed in the present invention can be ground into fine powder before mixing and granulation, the fine powder of near-infrared reflective dye and fine powder of titanium dioxide can each have a particle size of 200 nanometers to 1000 nanometers. This particle size range helps to improve the dispersibility of the fine powder of near-infrared reflective dye and fine powder of titanium dioxide in the fiber, thereby helping to form fine denier fibers.

[0029] In step S20, the fibers are woven to form a heat-resistant and UV-resistant fabric. In detail, the fibers can be woven into a knitted fabric or a woven fabric (e.g., a plain weave. In some embodiments, when the fabric is a woven fabric, the warp density of the fabric can be 190 to 210 strands / 10 cm, and the weft density can be 90 to 110 strands / 10 cm, thereby further enhancing the heat-resistant effect. After completing step S20, a heat-resistant and UV-resistant fabric having heat-resistant and UV-resistant properties can be obtained, and the color of the heat-resistant and UV-resistant fabric has a K / S value of 0.68 to 1.45. In other words, the heat-resistant and UV-resistant fabric formed at this stage has a relatively light and bright color.

[0030] In step S30, the heat-resistant and anti-ultraviolet fabric is post-processed and dyed. In detail, in response to the current fashion trend of dark fabrics, the heat-resistant and anti-ultraviolet fabric is dyed so that the heat-resistant and anti-ultraviolet fabric has a dark color. In some embodiments, the heat-resistant and anti-ultraviolet fabric can be placed in a dye solution (20 grams of dye solution is used for each gram of heat-resistant and anti-ultraviolet fabric), and the temperature is raised to 100°C at a rate of 1°C / minute, and after maintaining a constant temperature for 40 minutes, the temperature is lowered to 70°C at a rate of 1°C / minute to complete the dyeing. After the post-processing dyeing is completed, a dark-colored heat-resistant and anti-ultraviolet fabric with heat-resistant and anti-ultraviolet properties can be obtained. In detail, post-processing dyeing can deepen the color of the heat-resistant and anti-ultraviolet fabric to a K / S value of 3.05 to 3.60.

[0031] It should be understood that in the traditional preparation of fabrics with heat-resistant and UV-resistant properties, the materials used to make the fabrics with heat-resistant and UV-resistant properties often make it difficult for the fabrics to have a dark color through post-processing dyeing. Therefore, the method of liquid dyeing is often used to give the fabrics with heat-resistant and UV-resistant properties a dark color. However, this method requires additional mixing of masterbatches with the spinning raw materials during the previous fiber preparation process (spinning process), and spinning into fibers with the same color as the masterbatches after spinning. If the color to be formed is not the three primary colors, the masterbatches of the required colors must be prepared in advance, and the process is relatively cumbersome. Furthermore, after the high-temperature spinning process, the color may also be offset, resulting in the color of the final fiber being different from the expected color. In contrast, the present disclosure allows the raw materials used to prepare the fabric to include suitable and appropriate near-infrared reflective dyes (and titanium dioxide), so that the fabric can be suitable for being given a dark color through post-dyeing processing, which is more convenient and meets economic costs, and is conducive to mass production.

[0032] The following will refer to a number of embodiments and comparative examples to describe the features and effects of the present disclosure in more detail. It should be understood that the materials used, their amounts and proportions, processing details and processing procedures can be appropriately changed without exceeding the scope of the present disclosure. Therefore, the present disclosure should not be interpreted restrictively by the following embodiments. The components of the fibers in the heat-resistant and anti-ultraviolet fabrics of each embodiment and the fabrics of each comparative example and the proportion of each component in the fiber are shown in Table 1. The heat-resistant and anti-ultraviolet fabrics of Examples 1-3 are prepared through the steps S10-S20 of the above text, wherein in the process of mixing and granulation, the carrier is Nylon 6, the screw speed is 250rpm, and the mixing temperature is 250℃; in the process of melt spinning, the base material powder is Nylon 6, the melt spinning temperature is 250℃, and the spinning speed is 3500 meters / minute; the obtained fiber is a single-component fiber and has a fiber specification of 40 denier; the woven fabric is a plain weave of 40d / 12f. The heat-resistant and UV-resistant fabrics of Examples 4-6 are the heat-resistant and UV-resistant fabrics of Examples 1-3 after dyeing in step S30 above. Comparative Example 1 is a plain woven fabric woven from bright Nylon 6 fiber (the fabric specification is 40d / 12f). Comparative Example 2 is a plain woven fabric woven from semi-bright Nylon 6 fiber (the fabric specification is 40d / 12f). The fabric of Comparative Examples 3-4 is a masterbatch obtained by mixing titanium dioxide with Nylon 6 and kneading and granulating, and the masterbatch is mixed with Nylon 6 and melt-spun to form a 40-denier fiber, and then the fiber is woven into a 40d / 12f plain woven fabric, wherein during the kneading and granulation process, the screw speed is 250rpm and the kneading temperature is 250℃; during the melt spinning process, the melt spinning temperature is 250℃, and the spinning speed is 3500m / min. The fabrics of Comparative Examples 5-6 are the fabrics of Comparative Examples 3-4 after dyeing in step S30 above.

[0034]

[0035]

[0036] <Experimental Example 1: Thermal insulation test of fabric - temperature behind the fabric>

[0037] In this experimental example, a 120-watt infrared lamp was used to irradiate the fabric surface (front of the fabric) at a vertical distance of 30 cm for 1 minute, and the temperature behind the fabric was measured using a thermistor probe on a thermal insulation film temperature tester (product model: LS300, purchased from Linshang Technology). The results are shown in Table 2.

[0038] Table 2

[0039]

[0040]

[0041] From the results in Table 2, it can be seen that the temperature difference of each embodiment is less than or equal to the temperature difference of each comparative example, indicating that the heat-resistant and anti-ultraviolet fabric disclosed in the present invention has a better heat-resistant effect. In addition, from Examples 1-3 and Examples 4-6, when the proportion of near-infrared dye increases, the heat-resistant effect is improved. In addition, dyeing the fabric does not have a significant impact on its heat-resistant effect.

[0042] <Experimental Example 2: Thermal insulation test of fabric - fabric surface temperature>

[0043] In this experimental example, a 500-watt halogen lamp was used to irradiate the fabric surface (cloth surface) at a vertical distance of 100 cm for 10 minutes, and the temperature of the fabric surface was measured using a thermistor probe on a thermal insulation film temperature tester (product model: LS300, purchased from Linshang Technology). The results are shown in Table 3.

[0044] Table 3

[0045]

[0046]

[0047] From the results in Table 3, it can be seen that the temperature difference of each embodiment is smaller than that of each comparative example, indicating that the heat-resistant and anti-ultraviolet fabric disclosed in the present invention has a better heat-resistant effect. In addition, from comparative examples 3-4 and examples 1-2, the combination of near-infrared dye and titanium dioxide can improve the problem of insufficient reflection of titanium dioxide band, thereby achieving the effect of heat insulation and cooling. In addition, from examples 1-3 and examples 4-6, when the proportion of near-infrared dye increases, the heat-resistant effect is improved.

[0048] <Experimental Example 3: UV protection test of fabric>

[0049] In this experimental example, the AATCC183-2010 standard method is used to measure the ultraviolet protection factor (UPF) of the fabric. The results are shown in Table 4.

[0050] Table 4

[0051]

[0052] From the results of Table 4, it can be seen that Comparative Examples 1-2 have a significantly lower anti-ultraviolet index because no anti-ultraviolet raw materials are added; Comparative Examples 3-4 contain more than 1.0wt% of titanium dioxide, so the anti-ultraviolet index is 500 (the detection limit of the instrument), but from the experimental examples 1-2 in the previous text and the experimental example 4 in the following text, it can be seen that it does not have sufficient heat resistance and cannot be deeply dyed; from the results of Examples 1-2, it can be seen that when the content of near-infrared dye is increased, the anti-ultraviolet index will be correspondingly improved; from the results of Examples 2-3, it can be seen that when titanium dioxide is added, the anti-ultraviolet index will be correspondingly improved. Overall, adding an appropriate amount of titanium dioxide helps to improve the anti-ultraviolet performance of the fabric and ensures that the fabric can still be deeply dyed.

[0053] <Experimental Example 4: Post-processing dyeing test of fabric>

[0054] In this experimental example, a colorimeter was used to measure the La*b* value and K / S value of the fabric in the color space. The results are shown in Table 5.

[0055] Table 5

[0056]

[0057] From the results in Table 5, it can be seen that before post-processing dyeing, the K / S value of the fabric is relatively small, whether it is the comparative example or the example, and after post-processing dyeing, the K / S value of the fabric is significantly improved, which shows that the heat-resistant and UV-resistant fabric disclosed in the present invention can be post-processed and dyed like other fabrics without additional processing, and can achieve a dark dyeing effect. On the other hand, it can be found from Comparative Example 6 and Examples 4-6 that when the proportion of titanium dioxide is reduced, the fabric can have a darker color after dyeing, indicating that too much titanium dioxide is easy to fill the gaps in the fabric, making it difficult for the colorant to be effectively embedded in the fabric. In general, in the present disclosure, when the fibers in the fabric are made of a first raw material (containing near-infrared masterbatch but not anti-ultraviolet masterbatch), before post-processing dyeing, the color of the heat-resistant and anti-ultraviolet fabric has a K / S value of 1.35 to 1.45, and after post-processing dyeing, the color of the heat-resistant and anti-ultraviolet fabric has a K / S value of 3.50 to 3.60; when the fibers in the fabric are made of a second raw material (containing near-infrared masterbatch and anti-ultraviolet masterbatch), before post-processing dyeing, the color of the heat-resistant and anti-ultraviolet fabric has a K / S value of 0.68 to 0.94, and after post-processing dyeing, the color of the heat-resistant and anti-ultraviolet fabric has a K / S value of 3.05 to 3.20.

[0058] <Experimental Example 5: Fabric Dyeing Uniformity Test>

[0059] In this experimental example, the heat-resistant and anti-ultraviolet fabrics of Examples 4-6 (i.e., the dyed fabrics) were cut into 1-yard swatches, and the K / S values ​​of 8 points (i.e., 16 points in total) were measured on the front and back sides of the swatches, and the average value E1 of the 8 K / S values ​​on the front side and the average value E2 of the 8 K / S values ​​on the back side were calculated, and then the absolute value ΔE of the difference between the average values ​​E1 and E2 was calculated. The results showed that ΔE was 0.16, which shows that the heat-resistant and anti-ultraviolet fabrics disclosed in the present invention have small color difference after post-processing and dyeing, and have a high degree of color uniformity.

[0060] According to the above-mentioned embodiments of the present disclosure, the present disclosure provides a method for making a heat-resistant and anti-ultraviolet fabric. The heat-resistant and anti-ultraviolet fabric is prepared using raw materials. By allowing the raw materials to contain an appropriate amount of near-infrared reflective dye, not only can a fabric with heat-resistant and anti-ultraviolet properties be obtained, but the fabric can also be suitable for being given a dark color through post-processing dyeing. Compared with the traditional use of titanium dioxide-based additives to make the fabric have anti-ultraviolet properties, the present disclosure uses near-infrared reflective dyes to make the fabric have anti-ultraviolet properties, which can make the fabric be given a dark color after dyeing, which helps to improve the convenience of making dark fabrics and meet economic costs. In addition, adding an appropriate amount of titanium dioxide helps to improve the anti-ultraviolet properties of the fabric and ensure that the fabric can still be darkly dyed. In addition, making the fiber into a single-component form can overcome the problem of uneven dyeing and achieve an excellent uniform dyeing effect. Furthermore, making the fiber into a fine denier specification can also respond to the market trend of refinement and lightweight of sports and outdoor products.

[0061] Although the present disclosure has been disclosed in the above embodiments, it is not intended to limit the present disclosure. Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present disclosure.
