Description

Technical Field

[0001] The utility model belongs to the technical field of fabrics, and in particular relates to a cooling fabric and clothing. Background Art

[0002] With the development of the textile industry, the technical means to improve the ultraviolet protection factor (UPF value) are becoming more and more abundant, such as: selecting fibers and colors with good anti-ultraviolet effect, increasing fabric thickness and coverage factor, using mature finishing supporting processes, such as: high temperature and high pressure exhaustion method, coating method, resin padding method, etc. Relying on mature anti-ultraviolet textile technology, most of the sun protection clothing on the market can reach UPF40+, meeting people's needs for sun protection.

[0003] Focusing on the growing market demand for sun protection clothing, relying on mature weaving and finishing processes, while controlling costs, adopting reasonable fiber ratios and appropriate organizational structures, seeking more practical, comfortable, healthy and high-quality products, serving consumers while improving the market competitiveness of products. Today, sun protection clothing products of different price levels on the market have different characteristics. Most sun protection clothing within 100 advertises "ultraviolet blocking rate ≥ 99%", "UPF300+", "UPF1000+", and "ice silk". Consumers lack relevant knowledge and are often attracted by the gimmick of cheapness and sun protection and then buy them. In actual use, they often feel very stuffy, airtight, and uncomfortable. Because this type of product uses polyester fibers with excellent UV resistance but poor moisture absorption and air permeability, combined with thicker fabric structures or resin finishing, it can achieve high UPF values ​​and low costs, but this also sacrifices wearing comfort.

[0004] CN216006188U discloses a body temperature regulating and comfortable cooling fabric, comprising a hydrophilic fabric inner layer, a cooling fabric middle layer and a heat dissipating fabric outer layer arranged in sequence; the hydrophilic fabric inner layer is woven from a first yarn, the first yarn is cotton fiber, and a PCM phase change material layer is arranged in the hydrophilic fabric inner layer; the cooling fabric middle layer is woven from a second yarn, the second yarn is chitosan-modified jade fiber, so that the fabric produces a cooling effect of regulating body temperature, absorbing moisture and sweating, and dissipating heat and cooling. CN212765080U discloses a water storage and cooling fabric, comprising an outer layer of water permeable layer, an intermediate layer of water absorbing layer and an inner layer of waterproof layer, the water permeable layer, the water absorbing layer and the waterproof layer are adhered in sequence, the water absorbing layer is provided with criss-crossed diversion diffusion holes, the criss-crossed diversion diffusion holes form a diversion diffusion channel, and the water permeable layer is evenly provided with water permeable holes. The water-storing and cooling fabric includes an outer water-permeable layer, a middle water-absorbing layer and an inner waterproof layer. When in use, water can be poured on the outer layer. After water seeps through the water-permeable layer, the middle water-absorbing layer absorbs and stores water. The diversion and diffusion channel evenly diffuses the stored water. At the same time, the inner waterproof layer is waterproof. In this way, only the outer layer needs to be watered to ensure that water evaporation and cooling can be achieved for a period of time, but the UV protection performance is poor.

[0005] Therefore, developing a lightweight cooling fabric and clothing with UV protection function is an urgent problem to be solved in the art. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a cooling fabric and clothing that, based on body sensation, has the functions of sun protection, comfort, lightness and ultra-thinness, breathability, heat shielding and cooling, and excellent UV protection.

[0007] In order to achieve the purpose of this utility model, the utility model adopts the following technical solutions:

[0008] In a first aspect, the utility model provides a cooling fabric, the cooling fabric comprising a matte nylon and a shaped nylon combing bar GB1 and a spandex yarn combing bar GB2;

[0009] The comb bars GB1 and GB2 both adopt a warp plain weave structure, and the comb bars GB1 and GB2 both adopt a full-thread weave structure, and the directions of the formed weave structures are the same.

[0010] In the utility model, the matte nylon (manufacturer Hengshen, ordinary nylon) is a known material in the prior art and can be purchased through market channels.

[0011] In the utility model, the special-shaped nylon (manufacturer Hengshen, brand shielding yarn) is a known material in the prior art and can be purchased through market channels.

[0012] The matte nylon is nylon matte superfine denier FDY yarn 20D / 7F.

[0013] The shaped nylon is nylon shaped modified ultrafine FDY yarn 25D / 24F.

[0014] The structure of GB1 is 1-0 / 1-2 / / .

[0015] The structure of GB2 is 1-0 / 1-2 / / .

[0016] The transverse density of the cooling fabric is 30-40 W / cm, for example, 30 W / cm, 31 W / cm, 33 W / cm, 35 W / cm, 36 W / cm, 38 W / cm, 40 W / cm, and specific values ​​between the above values. Due to space limitations and for simplicity, the utility model does not exhaustively list the specific values ​​included in the range. W / cm is the number of vertical columns per unit centimeter.

[0017] The longitudinal density of the cooling fabric is 60-70 W / cm, for example, it can be 60 W / cm, 61 W / cm, 63 W / cm, 65 W / cm, 66 W / cm, 68 W / cm, 70 W / cm, and specific point values ​​between the above point values.
