Description

Technical Field

[0001] The present application relates to the technical field of textiles and clothing, and in particular to a sun-proof fabric and a preparation method thereof, as well as clothing. Background Art

[0002] The raw materials used for knitted sun protection clothing fabrics on the market are mainly nylon, and the cross-section of nylon is either round or flat and special-shaped, and it is pure color after dyeing. The function of knitted sun protection clothing fabrics is mainly to provide users with a cool feeling and anti-UV function. However, it is difficult for knitted sun protection clothing fabrics in the prior art to have both good soft and cool effect and good anti-ultraviolet function. For example, the darker the surface color of the fabric, the better the sun protection effect, but the more serious the heat absorption of the fabric. Especially when worn in summer, the dark surface color of the fabric needs to absorb a lot of heat when it has a good anti-ultraviolet function, so it cannot obtain a good cool effect. Summary of the invention

[0003] Based on this, it is necessary to provide a sunscreen fabric. The sunscreen fabric of the present invention can achieve an optimal balance between cool feeling, UV resistance and heat shielding, improve the cool feeling and softness of the fabric while improving the UV resistance of the fabric, and bring consumers a better wearing experience.

[0004] An embodiment of the present application provides a sun-proof fabric.

[0005] A sun-proof fabric is woven by circular cross-section yarns and special-shaped cross-section yarns, wherein the titanium dioxide content in the circular cross-section yarns is 1wt%-2.5wt%, and the titanium dioxide content in the special-shaped cross-section yarns is 3wt%-6wt%.

[0006] In some of these embodiments, the shape of the profiled-cross-section yarn includes at least one non-circular shape.

[0007] In some embodiments, the shape of the special-shaped cross-section yarn includes at least one of a cloud shape, a straight line shape, a triangle shape, a square shape, a polygon shape, and a peanut shape.

[0008] In some of the embodiments, the yarn specification of the circular cross-section yarn is 40D~100D.

[0009] In some of the embodiments, the yarn specification of the special-shaped cross-section yarn is 30D~70D.

[0010] In some of the embodiments, the circular cross-section yarn and the special-shaped cross-section yarn are dyed yarns, wherein the dyeing depth of the circular cross-section yarn is greater than the dyeing depth of the special-shaped cross-section yarn.

[0011] In some embodiments, the fibers of the circular cross-section yarn include nylon, nylon or polyester.

[0012] In some embodiments, the fibers of the profiled cross-section yarn include nylon, nylon or polyester.

[0013] In some embodiments, when the sun-protective fabric is weaved, the circular cross-section yarn and the special-shaped cross-section yarn are interlaced at intervals, and the ratio of the circular cross-section yarn to the special-shaped cross-section yarn is 1:1~5:1.

[0014] In some embodiments, when the sun-proof fabric is weaved, the circular cross-section yarn and the special-section yarn are woven in a double layer, and the ratio of the circular cross-section yarn to the special-section yarn in the lower layer of the sun-proof fabric is 1:1~5:1.

[0015] An embodiment of the present application also provides a method for preparing a sun-proof fabric.

[0016] A method for preparing a sun-proof fabric comprises the following steps:

[0017] The sunscreen fabric is formed by weaving circular cross-section yarn and profiled cross-section yarn, wherein the titanium dioxide content in the circular cross-section yarn is 1wt%~2.5wt%, and the titanium dioxide content in the profiled cross-section yarn is 3wt%~6wt%;

[0018] During weaving, the circular cross-section yarn and the special-section yarn are interlaced at intervals, and the ratio of the circular cross-section yarn to the special-section yarn is 1:1~5:1; or, the circular cross-section yarn and the special-section yarn are woven in a double layer, and the ratio of the circular cross-section yarn to the special-section yarn in the lower layer of the sun-proof fabric is 1:1~5:1.

[0019] A kind of clothing, characterized in that at least part of the clothing is made of the above-mentioned sun-proof fabric or the sun-proof fabric prepared by the above-mentioned preparation method.

[0020] In some of the embodiments, all parts of the clothing are made of the above-mentioned sun-protective fabric.

[0021] In some embodiments, the apparel includes clothes, shoes, hats, gloves, masks, sleeves, and face masks.

[0022] The sunscreen fabric of the present application is obtained by alternately weaving two yarns with different cross-sections and different titanium dioxide contents. Among them, the yarn with a circular cross-section in the sunscreen fabric can obtain a better cooling effect and a soft feel for the fabric, and the yarn with a special-shaped cross-section such as a straight line in the sunscreen fabric can better improve the covering property of the fabric, and improve the anti-ultraviolet performance and heat-shielding performance. The sunscreen fabric of the present application can effectively combine the characteristics of two yarns with different cross-sectional shapes, and use the difference in the performance of the two yarns to achieve an optimized balance of cooling, anti-ultraviolet and heat-shielding, bringing consumers a better wearing experience.

[0023] In summary, the sunscreen fabric obtained by alternately weaving two yarns with different cross-sections and different titanium dioxide contents has the following beneficial effects:

[0024] (1) The titanium dioxide content of yarns with circular cross-sections is low, while that of yarns with irregular cross-sections is high. The amount of dyeing is controlled by utilizing the characteristic that the dyeing rate of the irregular yarns with high titanium dioxide content is low during the dyeing process, so that the yarns with circular cross-sections are dark in color, while the yarns with irregular cross-sections are light in color, thus achieving a double-sided color effect in the form of stripes.

[0025] (2) The special-shaped cross-section yarn absorbs less heat and the high titanium dioxide content can improve the heat shielding effect, so as to achieve better heat-shielding and cooling effects of sun-protective fabrics.

[0026] (3) The circular cross-section yarn has a dark color, which can better absorb ultraviolet rays to improve UV resistance. At the same time, the circular cross-section yarn is mainly close to the skin, which can effectively improve the cooling effect of the sun protection fabric.

[0027] (4) The combination of circular cross-section yarn and special-shaped cross-section yarn, coupled with moisture absorption and drainage finishing, achieves better moisture absorption and quick-drying effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The embodiment of the present application provides a sunscreen fabric 10 to solve the problem that knitted sunscreen clothing fabrics in the prior art are difficult to have both good cooling effect and good anti-ultraviolet function. The sunscreen fabric 10 will be described below in conjunction with the accompanying drawings.

[0042] The sunscreen fabric 10 provided in the present application is exemplary, see Figure 1 As shown, Figure 1 The sunscreen fabric 10 of the present application can be used to prepare clothing that has both good cooling effect and good anti-ultraviolet function.

[0043] In order to more clearly illustrate the structure of the sun-proof fabric 10 , the sun-proof fabric 10 will be introduced below with reference to the accompanying drawings.

[0044] For example, see Figure 1 As shown, a sunscreen fabric 10 is woven from a circular cross-section yarn 100 and a profiled cross-section yarn 200. The titanium dioxide content in the circular cross-section yarn 100 is 1wt% to 2.5wt%, and the titanium dioxide content in the profiled cross-section yarn 200 is 3wt% to 6wt%.

[0045] The sunscreen fabric 10 of the present application is obtained by alternately weaving two yarns with different cross-sections and different titanium dioxide contents. The yarn with a circular cross-section in the sunscreen fabric 10 can provide the fabric with a better cooling effect and a soft feel. The yarn with a special cross-section such as a straight line in the sunscreen fabric 10 can provide the fabric with better covering, UV resistance and heat shielding properties. The sunscreen fabric 10 of the present application can effectively combine the characteristics of two yarns with different cross-sectional shapes, and utilize the difference in the performance of the two yarns to achieve an optimized balance between cooling, UV resistance and heat shielding, thus providing consumers with a better wearing experience.

[0046] In some of the embodiments, the titanium dioxide content in the circular cross-section yarn 100 includes, but is not limited to, 1 wt%, 1.3 wt%, 1.5 wt%, 1.8 wt%, 2 wt%, 2.5 wt% or a range between any two of the foregoing.

[0047] In some of the embodiments, the titanium dioxide content in the profiled cross-section yarn 200 includes, but is not limited to, 3wt%, 3.5wt%, 4wt%, 4.5wt%, 5wt%, 5.5wt%, 6wt% or a range between any two of the foregoing.

[0048] In some embodiments, the shape of the profiled cross-section yarn 200 includes at least one non-circular shape. It should be noted that the shape of the profiled cross-section yarn 200 mentioned above refers to the shape of the radial cross section of the profiled cross-section yarn 200. Figure 1 As shown, Figure 1 The angles shown are the shapes of the circular cross-section yarn 100 and the shapes of the profiled cross-section yarn 200. Figure 1 In the figure, the shape of the circular cross-section yarn 100 is circular, and the shape of the special-shaped cross-section yarn 200 is approximately a straight line.

[0049] In some of the embodiments, the shape of the special-shaped cross-section yarn 200 includes at least one of a cloud shape, a straight shape, a triangle, a square, a polygon, and a peanut shape.

[0050] Preferably, in a specific example, the shape of the special-shaped cross-section yarn 200 is approximately I-shaped.

[0051] For a specific example, see Figure 1 As shown, the shape of the profiled cross-section yarn 200 is a flat structure, approximately a straight line.

[0052] It is not difficult to understand that in other examples, the shape of the special-shaped cross-section yarn 200 can also be other irregular shapes, as long as the special-shaped cross-section yarn 200 can improve the covering property.

[0053] In some embodiments, the yarn specification of the circular cross-section yarn 100 is 40D to 100D. In some embodiments, the yarn specification of the circular cross-section yarn 100 includes but is not limited to: 40D, 50D, 60D, 70D, 80D, 90D, 100D or a range between any two of the foregoing.

[0054] In some embodiments, the yarn specification of the profiled cross-section yarn 200 is 30D to 70D. In some embodiments, the yarn specification of the profiled cross-section yarn 200 includes but is not limited to: 30D, 40D, 50D, 60D, 70D or a range between any two of the foregoing.

[0055] In some of the embodiments, the circular cross-section yarn 100 and the profiled cross-section yarn 200 are dyed yarns, wherein the dyeing depth of the circular cross-section yarn 100 is greater than the dyeing depth of the profiled cross-section yarn 200 .

[0056] In some of the embodiments, the dye is an acid blue dye. The acid blue dye used in the present application is an industrial dye widely used in textile dyeing, and is particularly suitable for dyeing protein fibers such as wool, silk and nylon. The characteristic of acid blue dye is that it contains one or more acidic groups in its molecular structure, such as sulfonic acid group (-SO3H), which enables them to dissolve in water and chemically combine with fibers in an acidic environment to achieve dyeing. The characteristics of acid blue dye include at least: (1) Water solubility: Acid blue dye has good water solubility and is easy to prepare into dye solution. (2) Bright color: The dyed fabric has bright color and a wide color spectrum. (3) Dyeing fastness: Fabrics dyed with acid blue dye usually have good sun exposure, washing and rubbing fastness. (4) Scope of application: Suitable for fibers such as wool, silk, nylon and nylon. When using acid blue dye to dye wool and silk, since these natural protein fibers are positively charged, they can form stable chemical bonds with negatively charged acid dyes under acidic conditions, so acid blue dye is very suitable for dyeing such materials. When dyeing nylon and nylon, although they are not protein fibers, their dyeing properties are similar to those of wool and are also suitable for using acid blue dyes.

[0057] In some of the embodiments, dyeing is preferably performed with a dye series that is sensitive to titanium dioxide, so as to minimize dyeing of the yarn with a special cross-section, increase the color difference between the yarn with a special cross-section and the yarn with a circular cross-section 100, make the stripes of the sun-proof fabric 10 more obvious, reduce the absorption of light by the yarn with a special cross-section, and improve the heat-shielding performance of the sun-proof fabric 10.

[0058] In some of these embodiments, the fibers of the circular cross-section yarn 100 include polyamide, nylon, or polyester.

[0059] In some embodiments, the fibers of the profiled-cross-section yarn 200 include nylon, nylon, or polyester.

[0060] In some of the embodiments, the circular cross-section yarn 100 and the special-shaped cross-section yarn 200 use different yarn combinations, such as the circular cross-section yarn 100 and the special-shaped cross-section yarn 200 respectively use a combination of polyester and nylon, and the circular cross-section yarn 100 and the special-shaped cross-section yarn 200 respectively use a combination of nylons with different properties, such as the circular cross-section yarn 100 and the special-shaped cross-section yarn 200 are nylon N66 and nylon N6, respectively.

[0061] In some embodiments, when the sunscreen fabric 10 is woven, the circular cross-section yarn 100 and the profiled cross-section yarn 200 are interlaced at intervals, and the number ratio of the circular cross-section yarn 100 to the profiled cross-section yarn 200 is 1:1 to 5:1. In some embodiments, when interlaced at intervals, the number ratio of the circular cross-section yarn 100 to the profiled cross-section yarn 200 includes but is not limited to: 1:1, 2:1, 3:1, 4:1, 5:1 or a range between any two of the foregoing.

[0062] In some embodiments, when the sunscreen fabric 10 is woven, the circular cross-section yarn 100 and the profiled cross-section yarn 200 are woven in a double-layer weaving method, and the ratio of the circular cross-section yarn 100 to the profiled cross-section yarn 200 in the lower layer of the sunscreen fabric 10 is 1:1 to 5:1. In some embodiments, when the double-layer weaving method is used, the ratio of the circular cross-section yarn 100 to the profiled cross-section yarn 200 includes but is not limited to: 1:1, 2:1, 3:1, 4:1, 5:1 or a range between any two of the foregoing.

[0063] An embodiment of the present application also provides a method for preparing a sun-proof fabric 10 .

[0064] It should be noted that, in the present application, unless otherwise specified, each reaction step may be carried out in the order described herein, or may not be carried out in the order described herein. For example, other steps may be included between each reaction step, and the order of the reaction steps may also be appropriately swapped. This can be determined by the technician based on conventional knowledge and experience. Preferably, the reaction method herein is carried out sequentially.

[0065] A method for preparing a sunscreen fabric 10 comprises the following steps:

[0066] The circular cross-section yarn 100 and the profiled cross-section yarn 200 are used to weave a sunscreen fabric 10, wherein the titanium dioxide content in the circular cross-section yarn 100 is 1wt%~2.5wt%, and the titanium dioxide content in the profiled cross-section yarn 200 is 3wt%~6wt%;

In some embodiments, when interlaced at intervals, the number ratio of the circular cross-section yarn 100 to the profiled cross-section yarn 200 includes but is not limited to: 1:1, 2:1, 3:1, 4:1, 5:1 or a range between any two of the foregoing. When the sunscreen fabric 10 is woven, the circular cross-section yarn 100 and the profiled cross-section yarn 200 are double-layer woven, and the number ratio of the circular cross-section yarn 100 to the profiled cross-section yarn 200 in the lower layer of the sunscreen fabric 10 is 1:1~5:1. In some embodiments, in the double-layer weaving method, the ratio of the circular cross-section yarn 100 to the profiled cross-section yarn 200 includes but is not limited to: 1:1, 2:1, 3:1, 4:1, 5:1 or a range between any two of the foregoing.

[0076] The circular cross-section yarn 100 and the profiled cross-section yarn 200 are dyed yarns after being dyed with acid blue dye, wherein the dyeing depth of the circular cross-section yarn 100 is greater than the dyeing depth of the profiled cross-section yarn 200. The two groups of yarns are dyed with acid blue dye, and after dyeing, there is an obvious difference in depth between the two groups of yarns.

[0105] The circular cross-section yarn 100 and the special-shaped cross-section yarn 200 are respectively N66 nylon and N6 nylon.

[0106] When the sun-proof fabric 10 is woven, the circular cross-section yarns 100 and the special-shaped cross-section yarns 200 are interlaced at intervals, and the number ratio of the circular cross-section yarns 100 to the special-shaped cross-section yarns 200 is 3:1.

[0107] Comparative Example 1

[0108] This comparative example provides a sun-proof fabric.

[0109] The sunscreen fabric of this comparative example is basically the same as that of Example 1, except that: in Comparative Example 1, no special-shaped cross-section yarn is contained, and the original special-shaped cross-section yarn is replaced by circular cross-section yarn.

[0110] Comparative Example 2

[0111] This comparative example provides a sun-proof fabric.

[0112] The sunscreen fabric of this comparative example is basically the same as that of Example 2, except that in Comparative Example 2, the titanium dioxide content in the circular cross-section yarn is 1 wt%, and the titanium dioxide content in the profiled cross-section yarn is 1 wt%.

[0113] Comparative Example 3

[0114] This comparative example provides a sun-proof fabric.

[0115] The sunscreen fabric of this comparative example is basically the same as that of Example 2, except that in Comparative Example 2, the titanium dioxide content in the circular cross-section yarn is 1wt%, and the titanium dioxide content in the profiled cross-section yarn is 8wt%.

[0116] Comparative Example 4

[0117] This comparative example provides a sun-proof fabric.

[0118] The sunscreen fabric of this comparative example is basically the same as that of Example 3, except that in Comparative Example 3, during weaving, the ratio of the number of circular cross-section yarns to the number of special-shaped cross-section yarns in the lower layer of the sunscreen fabric is 6:1.

[0119] Comparative Example 5

[0120] This comparative example provides a sun-proof fabric.

[0121] The sunscreen fabric of this comparative example is basically the same as that of Example 4, except that in Comparative Example 4, during weaving, the titanium dioxide content in the circular cross-section yarn is 3.5wt%, and the titanium dioxide content in the profiled cross-section yarn is 3.5wt%.

[0122] Comparative Example 6

[0123] This comparative example provides a sun-proof fabric.

[0124] The sunscreen fabric of this comparative example is basically the same as that of Example 4, except that in Comparative Example 4, during weaving, the titanium dioxide content in the circular cross-section yarn is 0.5wt%, and the titanium dioxide content in the profiled cross-section yarn is 5wt%.

[0125] Performance tests were performed on the sunscreen fabrics 10 in Examples 1 to 5 and Comparative Examples 1 to 6, and the test results are shown in Table 1.

[0126] Table 1

[0127]

[0128] As can be seen from Table 1, Comparative Example 1 does not contain profiled cross-section yarns. After the original profiled cross-section yarns are replaced by circular cross-section yarns, the anti-UV performance and heat shielding rate are significantly reduced. In Comparative Example 2, when the titanium dioxide content in the profiled cross-section yarn is 1wt%, the anti-UV performance and heat shielding rate of the sunscreen fabric are worse than those in Example 2. In Comparative Example 3, when the titanium dioxide content in the profiled cross-section yarn is too much, it is 8wt%. Although the anti-UV performance and heat shielding rate are improved, it is easy to cause yarn breakage during yarn preparation, and the fabric is prone to breakage in actual production. Therefore, the titanium dioxide content in the profiled cross-section yarn should not be too much. In Comparative Example 4, when the ratio of the number of circular cross-section yarns to the number of profiled cross-section yarns in the lower layer of the sunscreen fabric is 6:1, the number of profiled cross-section yarns is how much, resulting in anti-UV performance and heat shielding rate being worse than Example 3. In Comparative Example 5, the titanium dioxide content in the circular cross-section yarn is less, resulting in poor anti-UV performance and heat shielding rate compared with Example 4. In Comparative Example 6, the titanium dioxide content in the circular cross-section yarn is too high. Although the anti-UV performance and heat shielding rate are improved, it is easy to cause yarn breakage during yarn preparation, and the fabric is prone to breakage in actual production. Therefore, the titanium dioxide content in the profiled cross-section yarn should not be too much. Therefore, in this application, the titanium dioxide content in the circular cross-section yarn 100 is 1wt%~2.5wt%, and the titanium dioxide content in the profiled cross-section yarn 200 is preferably 3wt%~6wt%.

[0129] In summary, the sunscreen fabric 10 obtained by alternately weaving two yarns with different cross-sections and different titanium dioxide contents has the following beneficial effects:

[0130] (1) The titanium dioxide content of yarns with circular cross-sections is low, while that of yarns with irregular cross-sections is high. The amount of dyeing is controlled by utilizing the characteristic that the dyeing rate of the irregular yarns with high titanium dioxide content is low during the dyeing process, so that the yarns with circular cross-sections are dark in color, while the yarns with irregular cross-sections are light in color, thus achieving a double-sided color effect in the form of stripes.

[0131] (2) The special-shaped cross-section yarn absorbs less heat and the high titanium dioxide content can improve the heat shielding effect to achieve a better heat-shielding and cooling effect of the sun-protective fabric 10.

[0132] (3) The circular cross-section yarn has a dark color, which can better absorb ultraviolet rays to improve the anti-UV ability. At the same time, the circular cross-section yarn is mainly close to the skin, which can effectively improve the cooling effect of the sun protection fabric 10.

[0133] (4) The combination of circular cross-section yarn and special-shaped cross-section yarn, coupled with moisture absorption and drainage finishing, achieves better moisture absorption and quick-drying effect.
