Description

Technical Field

[0001] The utility model relates to the technical field of textile manufacturing, in particular to a breathable sunscreen fabric. Background Art

[0002] With the continuous improvement of people's health awareness, the harm of ultraviolet (UV) radiation to human health has received increasing attention. Ultraviolet rays can not only cause skin sunburn and pigmentation, but also may lead to skin aging and even skin cancer. Therefore, consumers' demand for products with protection functions is increasing rapidly.

[0003] In recent years, a variety of sunscreen clothes have emerged on the market. In order to achieve sufficient sunscreen effect, some sunscreen clothes are often heavy, not easy to carry, and cause discomfort when worn; for traditional woven sunscreen clothes, in order to achieve the characteristics of being light and thin and having sunscreen function, the density of the sunscreen fabric is often very large, which results in poor air permeability and is extremely easy to produce a stuffy feeling when worn; in recent years, many companies have developed knitted sunscreen clothes. Because the coil structure of the knitted fabric is more three-dimensional than that of the traditional woven sunscreen fabric, its air permeability has been improved to a certain extent. However, when worn in a hot summer under strong sunlight, it will still be relatively stuffy.

[0004] In summary, there is an urgent need to provide a sunscreen fabric with good air permeability. Summary of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a breathable sunscreen fabric.

[0006] The utility model adopts the following technical solutions:

[0007] The utility model discloses a breathable sunscreen fabric, which includes a plurality of surface layers fixedly connected. The plurality of surface layers have a dense area and a sparse area, and the yarn density of the dense area is greater than that of the sparse area; when projected from a direction perpendicular to the breathable sunscreen fabric, the dense area completely covers the sparse area. It should be noted that the dense area can help prevent sunlight from passing through and achieve a good sunscreen effect; the sparse structure can facilitate air circulation and help improve air permeability; the dense area completely covering the sparse area can ensure good sunscreen performance and good air permeability.

[0008] In one implementation manner of the utility model, the density of the dense area is: 140 to 220 warp ends per inch, 100 to 120 weft picks per inch; the density of the sparse area is: 60 to 120 warp ends per inch, 50 to 60 weft picks per inch. It should be noted that making the dense area and the sparse area have appropriate densities can help ensure good sunscreen performance and good air permeability.

[0009] In one implementation of the present utility model, the dense area or the sparse area is strip-shaped or grid-shaped, and is distributed cyclically along the warp direction, the weft direction, or both the warp and weft directions simultaneously. It should be noted that in this case, it is beneficial for processing.

[0010] In one implementation of the present utility model, the width of the dense area is 1 cm to 2 cm, and the width of the sparse area is 0.5 cm to 1 cm. It should be noted that making the dense area and the sparse area have appropriate sizes is beneficial for ensuring good sun protection performance and good air permeability.

[0011] In one implementation of the present utility model, the breathable sun protection fabric includes a first surface layer and a second surface layer that are fixedly connected. It should be noted that the sun protection fabric contains two surface layers, which is beneficial for ensuring the lightness of the sun protection fabric.

[0012] In one implementation of the present utility model, the multiple surface layers are connected by a hanging point structure. It should be noted that connecting the multiple surface layers by hanging points is beneficial for the stable combination between the surface layers. In addition, after fixing the two surface layers together through the hanging points, a cavity or gap will be formed between the two surface layers. The existence of the cavity increases the space for air circulation and can improve the air permeability of the fabric.

[0013] In one implementation of the present utility model, the interval of the hanging point structure is 0.5 cm to 1.5 cm. It should be noted that making the hanging point structures have an appropriate spacing is beneficial for ensuring the stability and air permeability of the fabric structure.

[0014] In one implementation of the present utility model, the surfaces of the multiple surface layers have multiple three-dimensional folds. It should be noted that the three-dimensional folds will increase the gap between the two layers in the vertical direction of the fabric, which is beneficial for air permeability.

[0015] In one implementation of the present utility model, the fineness of the yarn used for the breathable sun protection fabric is 60S to 80S, and the fabric weight of the breathable sun protection fabric does not exceed 160 g / m 2 . It should be noted that in this case, the fabric can have good comprehensive properties of lightness, sun protection, and air permeability.

[0016] In one implementation of the present utility model, the material of the breathable sun protection fabric is at least one of cotton and linen. It should be noted that compared with materials such as polyester fiber, cotton and linen are more breathable and comfortable.

[0017] Due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0018] In the breathable sunscreen fabric of the present utility model, the dense area can help prevent sunlight from passing through, achieving a good sunscreen effect; the sparse structure can facilitate air circulation and help improve breathability; the dense area of the sunscreen fabric of the present utility model completely covers the sparse area, ensuring good sunscreen performance and good breathability.

[0026] Traditional woven sunscreen clothing, in order to achieve the characteristics of being lightweight and sunscreen, often has a very high density of sunscreen fabric, which results in poor breathability and is extremely prone to a stuffy feeling when worn; in recent years, many companies have developed knitted sunscreen clothing. Since the coil structure of knitted fabric is more three-dimensional than that of traditional woven sunscreen fabric, its breathability has been improved to a certain extent. However, in the hot summer, it will still be relatively stuffy when worn in an environment with strong sunlight. In view of this, the present utility model creatively proposes a breathable sunscreen fabric. Hereinafter, the breathable sunscreen fabric (hereinafter sometimes simply referred to as "sunscreen fabric" or "fabric") of the present utility model will be described in detail in combination with specific embodiments and drawings.

[0027] Figure 1 It is a schematic structural diagram of the sunscreen fabric 100 involved in the present utility model.

[0028] In a specific embodiment, the material of the sunscreen fabric 100 is at least one of polyester fiber, nylon, polyester, cotton, and linen. Preferably, the material of the sunscreen fabric 100 is at least one of cotton and linen. Thus, the material is relatively breathable.

[0029] In a specific embodiment, the fabric weight of the sunscreen fabric 100 does not exceed 160 g / m 2 . Thus, it can be relatively lightweight.

[0030] In a specific embodiment, the fineness of the yarn used in the sunscreen fabric 100 is 60S - 80S (S represents the English count). Thus, it can ensure a good sunscreen effect while making the sunscreen fabric relatively lightweight.

[0031] In a specific embodiment, the sunscreen fabric 100 includes multiple surface layers.

[0032] In a specific embodiment, the multiple surface layers are fixedly connected.

[0033] As Figure 1 shown, in a specific embodiment, the sunscreen fabric 100 may include two surface layers, namely a first surface layer 10 and a second surface layer 20.

[0034] In a specific embodiment, the first surface layer 10 may be the outer layer close to the external environment, and the second surface layer 20 may be the inner layer close to the human body.

[0035] In a specific embodiment, the first surface layer 10 and the second surface layer 20 may be fixedly connected through a hanging point structure 50.

[0036] In a specific embodiment, the hanging point method may be that the warp yarn of the first surface layer 10 hangs the weft yarn of the second surface layer 20.

[0037] In a specific embodiment, multiple surface layers have a dense area 30 and a sparse area 40, where the yarn density in the dense area 30 is greater than that in the sparse area 40. That is to say, the dense area refers to the area with a higher yarn density, and the sparse area refers to the area with a lower yarn density.

[0038] In a specific embodiment, the density of the dense area 30 is: 140 to 220 warp ends per inch and 100 to 120 weft picks per inch.

[0039] In a specific embodiment, the density of the sparse area 40 is: 60 to 120 warp ends per inch and 50 to 60 weft picks per inch.

[0040] In a specific embodiment, when projected from a direction perpendicular to the sunscreen fabric 100, the dense area 30 completely covers the sparse area 40.

[0041] In a specific embodiment, the area of a certain dense area 30 can be 2 to 4 times the area of its corresponding sparse area 40.

[0042] In a specific embodiment, the dense area 30 and the sparse area 40 can be in strip or grid shape.

[0043] In a specific embodiment, the width of the dense area 30 can be 1 cm to 2 cm. Preferably, the width of the dense area 30 can be 1.6 cm to 2 cm.

[0044] In a specific embodiment, the width of the sparse area 40 can be 0.5 cm to 1 cm. Preferably, the width of the sparse area 40 can be 0.8 cm to 1 cm.

[0045] In a specific embodiment, the interval between multiple hanging point structures 50 can be 0.5 cm to 1.5 cm. Preferably, the interval between multiple hanging point structures 50 can be 0.8 cm to 1.2 cm.

[0046] The following gives an exemplary illustration of several typical distribution cases of the dense area 30 and the sparse area 40.

[0047] Figure 2 is a schematic structural diagram of the sunscreen fabric 100 with the dense area 30 and the sparse area 40 distributed in a weft-wise cycle according to the present invention, Figure 3 is a schematic structural diagram of the sunscreen fabric 100 with the dense area 30 and the sparse area 40 distributed in a warp-wise cycle according to the present invention, Figure 4 is a schematic structural diagram of the sunscreen fabric 100 with the dense area 30 and the sparse area 40 distributed in both warp-wise and weft-wise cycles according to the present invention.

[0048] Such as Figures 2 to 4As shown, both the first surface layer 10 and the second surface layer 20 have multiple dense areas 30 and sparse areas 40. The dense areas 30 and the sparse areas 40 are arranged at intervals, and when projected along the direction perpendicular to the surface layer, the dense areas 30 completely cover the sparse areas 40.

[0049] Figure 2 In [description], the dense areas 30 or the sparse areas 40 in the first surface layer 10 and the second surface layer 20 are strip-shaped, and the dense areas 30 and the sparse areas 40 are distributed in a cycle along the weft direction X.

[0050] Figure 3 In [description], the dense areas 30 or the sparse areas 40 in the first surface layer 10 and the second surface layer 20, and the dense areas 30 and the sparse areas 40 are distributed in a cycle along the warp direction Y.

[0051] Figure 4 In [description], the sparse areas 40 in the first surface layer 10 and the second surface layer 20 are square-shaped and are distributed in a cycle along the warp and weft directions.

[0052] It should be noted that the shapes of the dense areas 30 and the sparse areas 40 can also be other regular shapes such as rhombus, trapezoid, circle, ellipse, heart shape, star shape, etc., or can be irregular shapes.

[0053] It should be noted that Figures 1 to 4 only the case where the number of surface layers of the sunscreen fabric 100 is two is described. According to actual needs, the number of surface layers can be three, four or more layers, as long as the dense areas 30 completely cover the sparse areas 40.

[0054] In a specific embodiment, the sunscreen fabric 100 can have multiple three-dimensional folds.

[0055] In a specific embodiment, three-dimensional folds can be produced by a water washing process. In order to achieve a relatively uniform wrinkling effect, the warp yarns are twisted with Z twist and the weft yarns are twisted with S twist. It should be noted that the three-dimensional folds will increase the gap between the two layers in the vertical direction of the fabric, which is beneficial to ventilation. In the present utility model, through the combination of a sparse structure and three-dimensional folds, the air permeability is greatly improved. According to the air permeability test of the national standard GB / T 5453-1997, the air permeability of traditional sunscreen clothing generally does not exceed 210 mm / s, and the air permeability of the sunscreen fabric of the present utility model is generally greater than 800 mm / s.

[0056] In a specific embodiment, the distance between adjacent three-dimensional folds between two surface layers is more than 1 mm.

[0057] In a specific embodiment, the sunscreen fabric 100 can be added with sunscreen additives. Thus, it is beneficial to achieve a better sunscreen effect.

[0058] In a specific embodiment, the sunscreen additive can be an ultraviolet absorber.

[0059] In a specific embodiment, the air permeability of the sunscreen fabric 100 exceeds 800 mm / s.

[0060] In a specific embodiment, the present utility model provides a sunscreen clothing, and at least part of the sunscreen clothing can be made of the above-mentioned sunscreen fabric 100.

[0061] The present utility model will be further described below in conjunction with specific embodiments. It should be understood that the embodiments are only exemplary and do not constitute a limitation on the protection scope of the present utility model.
