Description

Technical Field

[0001] This utility model relates to the field of functional fabrics, specifically to a lightweight sun-protective fabric. Background Technology

[0002] In recent years, with the intensification of global climate change and environmental pollution, the demand for sun protection products has increased significantly. Sun-protective clothing, as a convenient and effective means of protection, is increasingly favored by consumers. Especially in summer or in areas with strong ultraviolet radiation, sun-protective clothing has become an essential item in people's daily lives. However, most existing sun-protective clothing fabrics on the market suffer from problems such as heavy weight, poor breathability, and insufficient comfort, making it difficult to fully meet consumer needs. Therefore, developing a knitted fabric that combines lightweight, sun protection, and comfort has significant market value and broad application prospects.

[0003] However, achieving excellent sun protection while maintaining the lightweight and comfort of the fabric remains a technical challenge. Currently, most sun-protective fabrics on the market achieve this through chemical treatment or the addition of sun-protective coatings. While these methods provide some sun protection, they often compromise the fabric's breathability and comfort, and may even have negative impacts on the environment and human health. Furthermore, since sun-protective clothing is frequently used in summer or outdoor settings, it needs to be stored indoors. Typical sun-protective fabrics require extremely dense weaves to block UV rays, inevitably increasing their weight. Therefore, there is a greater need for sun-protective fabrics that are easy to store. Developing a fabric that is lighter in weight while maintaining excellent sun protection remains a challenge to be solved. Summary of the Invention

[0004] Purpose of the invention: In order to solve the technical problems existing in the prior art, this utility model aims to provide a lightweight sun protection fabric that combines breathability and comfort.

[0005] Technical solution: The lightweight sun-protective fabric of this utility model is woven from yarn one with ultraviolet absorption function and yarn two with high elasticity; wherein, the padding numbers of yarn one and yarn two are both 0-1 / 2-1 / 3-2 / 1-2 / / , or, yarn one is 1-0 / 1-2 / 2-3 / 2-1 / / , and yarn two is 2-3 / 2-1 / 1-0 / 1-2 / / ; the yarn one and yarn two are both fully threaded.

[0006] Furthermore, the yarn is sun-protective nylon with specifications of 20D / 17f FD FDY.

[0007] Furthermore, the second yarn is spandex with a specification of 20D.

[0008] Furthermore, the weight of the lightweight sun-protective fabric is 98-108 gsm.

[0009] Furthermore, the lightweight sun-protective fabric has a UPF value of 120-138.

[0010] Furthermore, the lightweight sun-protective fabric also includes a cooling layer on its surface.

[0011] Invention Principle: In this invention, composite yarns are selected as the raw materials for lightweight sun-protective fabrics. Yarn one is a UV-absorbing yarn, specifically sun-protective nylon 6, containing UV absorbers, giving the yarn itself a strong UV absorption function and reducing transmittance. Yarn two is spandex, and a special composite weaving process is designed: using the above-mentioned fine denier composite yarns on a high-needle count machine to create a special uneven fabric appearance. The principle is to utilize the elasticity of spandex and the growth of the take-up channel to achieve full shrinkage of the fabric, causing the yarns on the fabric surface to arch and form an uneven appearance. At the same time, the fabric forms a multi-layered structure, blocking UV rays layer by layer, with each layer interlacing with the others. This special weaving process allows the fabric to maintain a very light weight while blocking UV rays, while also maintaining good breathability and adding a cooling layer to keep the fabric's skin-contact surface cool.

[0012] In summary, by optimizing yarn materials and weaving processes, this invention not only maintains excellent sun protection performance but also significantly reduces the weight of the fabric while providing softness and breathability.

[0013] Beneficial effects: Compared with the prior art, the present invention has the following advantages: The yarn with ultraviolet absorption function and the yarn with high elasticity in the present invention are knitted with a special structure of high needle count, so that the fabric has a specific uneven micro-texture appearance, which has a good blocking effect on ultraviolet rays while maintaining an ultra-light weight, and at the same time has good breathability and dimensional stability, and is widely applicable.

[0018] The present invention will now be further described in conjunction with specific embodiments and accompanying drawings.

[0019] Example 1: The lightweight sun protection fabric provided in this example is woven from yarn 1, which has the function of absorbing ultraviolet rays, and yarn 2, which has high elasticity. Yarn 1 GB1 is sun protection nylon 6 with a specification of 20D / 17f FD FDY, and yarn 2 GB2 is spandex with a specification of 20D.

[0020] Fabric 1 is woven from yarn 1 and yarn 2. The padding numbers for both yarn 1 (GB1) and yarn 2 (GB2) are 0-1 / 2-1 / 3-2 / 1-2 / / , and the structure is as follows: Figure 1 As shown, both yarn 1 GB1 and yarn 2 GB2 are threaded using the full threading method.

[0021] Example 2: The lightweight sun protection fabric 2 provided in this example is woven from yarn 1, which has the function of absorbing ultraviolet rays, and yarn 2, which has high elasticity. Yarn 1 GB1 is sun protection nylon 6 with a specification of 20D / 17f FD FDY, and yarn 2 is spandex with a specification of 20D.

[0022] Fabric 2 is woven from yarn 1 and yarn 2 together. The padding yarn number of yarn 1 (GB1) is 1-0 / 1-2 / 2-3 / 2-1 / / , and the structure is as follows: Figure 2 As shown, the padding yarn number for yarn 2 GB2 is 2-3 / 2-1 / 1-0 / 1-2 / / , and the structure is as follows: Figure 3 As shown; both yarn one and yarn two are threaded using the full threading method.

[0023] Comparative Example 1: The difference from Example 1 is that ordinary nylon 6 is used instead of sunscreen nylon 6 for yarn 1 GB1, and the padding numbers of yarn 1 GB1 and yarn 2 GB2 are both 0-1 / 2-1 / 3-2 / 1-2 / / .

[0024] Comparative Example 2: The difference from Example 2 is that ordinary nylon 6 was used instead of sunscreen nylon 6 for yarn GB1.
