Description

Technical Field

[0001] This utility model belongs to the field of fabric technology, specifically relating to a multifunctional UV-resistant fabric. Background Technology

[0002] In recent years, outdoor sports such as mountaineering, hiking, cycling, and running have become increasingly popular. During these activities, people are exposed to sunlight for extended periods, requiring fabrics to provide sufficient UV protection and a cooling sensation against the skin. Chinese patent document (CN116285323A) discloses a cooling UV-resistant fiber, which uses melt spinning of a cooling UV-resistant masterbatch and a base masterbatch. The masterbatch contains cooling and UV-resistant factors, resulting in a product with a UPF value of 50+ and an instantaneous cooling sensation of 0.2 or higher. However, this type of cooling UV-resistant fiber has a circular cross-section, a single fiber DPF value greater than 1, and the yarn obtained from spinning multiple single fibers also has a roughly circular cross-section. Its moisture-wicking ability is relatively average, and it tends to stick to the skin after sweating. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a multifunctional UV-resistant fabric that meets the requirements of UV protection product standards while also having moisture-wicking function.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A multifunctional UV-resistant fabric includes a woven body and a single-sided moisture-wicking finishing layer. The woven body is made of interwoven warp and weft yarns. Both the warp and weft yarns are UV-resistant and cooling yarns with a cross-sectional shape resembling a cloud and forming moisture-wicking grooves on the surface. The DPF value of the warp and weft yarns is less than 1. The single-sided moisture-wicking finishing layer is obtained by spraying a moisture-wicking finishing liquid onto the outer surface of the woven body and then setting it.

[0006] Preferably, both the warp and weft yarns are FDY or DTY.

[0007] Preferably, the denier of the warp and weft yarns is 20D-35D.

[0008] Preferably, the warp density of the woven body is 200 T / 10cm-220 T / 10cm, and the weft density of the woven body is 150 T / 10cm-185 T / 10cm.

[0009] Preferably, the moisture-absorbing finishing liquid is a hydrophilic silicone oil.

[0010] Preferably, the hydrophilic silicone oil is RUCOFIN HHS.

[0011] Preferably, the woven body is a tri-phase weave.

[0012] Preferably, the woven body is a double weft structure, and the weft yarn is divided into inner weft and outer weft, with the ratio of inner weft to outer weft being 1:1.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model relates to an anti-UV fabric comprising a single-sided moisture-wicking finishing layer on the outer surface of a woven body. Firstly, the woven body uses an anti-UV cooling yarn with a cloud-like cross-section and moisture-wicking grooves on its surface, and a DPF value less than 1. Utilizing this cross-sectional shape, surface characteristics, and capillary effect, the moisture-wicking capacity of the anti-UV cooling yarn itself is greatly enhanced. Secondly, the single-sided moisture-wicking finishing layer, obtained by spraying and finishing the woven body, significantly enhances the moisture-wicking capacity of the outer surface, creating a moisture-wicking gradient between the inside and outside of the fabric. This utility model combines these two aspects to give the fabric excellent unidirectional moisture-wicking and perspiration-wicking properties.

[0015] In addition, the cloud-like cross-section of the UV-resistant cooling yarn can significantly increase the contact area between the skin and the fabric, giving the skin an excellent cooling effect. At the same time, due to the unevenness of the cross-section, it can increase the diffuse reflection of infrared and ultraviolet rays, thereby achieving the effects of cooling and UV protection.

[0016] The initial UPF of the fabric of this utility model AV The value reaches over 200, while the UPF value is higher after 30 standard water washes. AV The value remains above 100, and after 30 standard water washes, the instantaneous cooling sensation upon contact still reaches 0.2 J / (cm). 2 *s) and above. Attached Figure Description

[0022] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation. Example 1

[0023] like Figure 1 and Figure 2 As shown, this embodiment provides a multifunctional UV-resistant fabric, including a single-sided moisture-absorbing finishing layer 1 and a woven body 2. The woven body 2 is made of multiple warp yarns 23 and multiple weft yarns interlaced to form a plain weave structure (note that in some other examples, a twill weave or satin weave from the three-component structure can be used instead of a plain weave structure. The weave diagram of the three-component structure is well known and will not be described in detail here). The single-sided moisture-absorbing finishing layer is obtained by spraying a moisture-absorbing finishing liquid onto the outer surface of the woven body and then shaping and finishing it.

[0024] In this embodiment, the moisture-absorbing finishing liquid is a hydrophilic silicone oil, specifically a mixture of Rudolf RUCOFIN HHS hydrophilic moisture absorbent and water. Its main component is polysiloxane, which can give a very soft, fluffy, and smooth feel, while also having excellent hydrophilic properties.

[0025] In this embodiment, both the warp yarn 23 and the weft yarn are made of UV-resistant cooling yarn 20, and the cross-sectional shape of the UV-resistant cooling yarn 20 is a straight cloud cross-section, such as... Figure 2 As shown, the cross-section of the cloud pattern consists of three flat ellipses connected in a straight line, forming axially extending grooves on both sides of adjacent areas. These grooves serve as moisture-wicking grooves on the surface of the UV-resistant cooling yarn 20. These moisture-wicking grooves enhance the moisture-wicking ability of the UV-resistant cooling yarn 20, while the cloud pattern significantly increases the contact area between the skin and the fabric, giving the skin an excellent cooling effect. At the same time, due to the concave-convex nature of the cross-section, it helps to increase the diffuse reflection of infrared and ultraviolet rays, thereby achieving the effects of cooling and UV protection.

[0026] The UV-resistant cooling yarn 20 has an FDY yarn form with a warp density of 200 T / 10cm-220 T / 10cm and a weft density of 150 T / 10cm-185 T / 10cm for the woven body. In other examples, the UV-resistant cooling yarn 20 can also have a DTY yarn form. The UV-resistant cooling yarn 20 has a denier of 20D-35D and a DPF value of less than 1, which increases the specific surface area of ​​the fiber, makes the capillary effect more significant, and improves the moisture absorption performance. Example 2

[0027] This embodiment provides a multifunctional UV-resistant fabric, differing from Embodiment 1 above only in that the weave structure is changed to a double-weft weave. Figure 3-4As shown, the weft yarn is divided into inner weft 22 and outer weft 21, and the ratio of inner weft 22 to outer weft 21 is 1:1.

[0028] The foregoing has shown and described the basic principles and main features of this invention, as well as its advantages. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications can be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
