Description

Technical Field

[0001] The utility model belongs to the field of functional fabrics, and in particular relates to a cool, breathable and sun-proof fabric. Background Art

[0002] With the improvement of people's living standards and the deterioration of the environment, our lifestyle is quietly changing, and people are paying more and more attention to leisure and outdoor activities. When consumers choose to relax and entertain outdoors, using textiles to protect against ultraviolet rays has always been a very important choice. The hot sun protection clothing market in recent years has also brought about the flourishing of sun protection clothing fabrics, with manufacturing methods ranging from knitting to weaving, and materials ranging from polyester, nylon to natural fibers.

[0003] As people's requirements for clothing comfort increase, good sun protection clothing should not only have anti-ultraviolet performance, but also have comfortable properties such as lightness, breathability, and coolness. In order to achieve the ideal anti-ultraviolet effect, the woven sun protection clothing fabrics on the market usually have a relatively tight structure; such fabrics have poor air permeability and poor elasticity, and the resulting clothing will be stiff and uncomfortable to wear. Therefore, a new fabric is needed to solve the problems of poor air permeability, low elasticity, and stuffiness of woven sun protection fabrics. Utility Model Content

[0004] Purpose of the utility model: The purpose of the utility model is to provide a lightweight, UV-resistant, highly breathable, cool and breathable sun-protective fabric.

[0005] Technical solution: The utility model discloses a cool, breathable and sun-proof fabric, comprising warp yarn and weft yarn, wherein the warp yarn is a cooling functional yarn, the weft yarn is an anti-ultraviolet functional yarn coated with spandex elastic fiber, and the warp yarn and the weft yarn are interwoven in a hexagonal honeycomb structure.

[0006] Furthermore, the cooling functional yarn is semi-bright nylon DTY cooling yarn.

[0007] Furthermore, the semi-gloss nylon DTY cooling yarn is 15D / 5F.

[0008] Furthermore, the anti-ultraviolet functional yarn is 20D / 7F nylon DTY anti-ultraviolet yarn.

[0009] Furthermore, the spandex elastic fiber is 20D.

[0010] Furthermore, the warp and weft density of the finished cool, breathable and sun-proof fabric is 100×76T / cm, and the gram weight of the finished fabric is 59±2g / m 2 .

[0011] Beneficial effects: Compared with the prior art, the utility model has the following advantages: 1. By optimizing the warp and weft yarn combination of conventional woven sunscreen fabrics, more functions are given to the fabrics. The hexagonal honeycomb structure can greatly increase the air permeability of the fabric without affecting the sunscreen effect; 2. By introducing the cooling functional yarn, it has excellent instant contact coolness, and the wearer can intuitively feel the coolness effect; 3. By using anti-ultraviolet functional yarns in the weft direction to cover the spandex elastic fiber, excellent anti-ultraviolet effect and excellent elasticity are achieved. The anti-ultraviolet effect UPF value of the sunscreen fabric is greater than 50, the air permeability is 60-80mm / s, and the instantaneous coolness QMAX value of contact is greater than 0.23J / cm 2 ·s, with excellent UV protection, air permeability and cooling effects as a whole; 4. Reasonable combination from fiber to tissue structure allows functional yarn to be given more functions on the sun-protective clothing fabric, which can further improve the wearing experience of woven sun-protective clothing. The characteristics of lightweight, UV resistance, high air permeability, and cooling can better meet the functional needs of current consumers for sun-protective clothing, and have good market application prospects and economic value.
