Description

Technical Field

[0001] The utility model relates to the technical field of textile fabrics, and more specifically, to a high-breathable cool-feeling yarn fabric. Background Art

[0002] Various artificial fibers and natural fibers are twisted to form single yarns, and then the single yarns are twisted or compound twisted to form ply yarns, and then the ply yarns are woven through a shuttle loom according to a certain weaving method to form textile fabrics with specific structures, which are woven fabrics. Fabrics with different structures have different functions and styles to meet people's needs.

[0003] Woven fabrics play a very important role in daily life and are usually used as raw materials for making all kinds of clothing and accessories. The most important property that people require of clothing and accessories is comfort. Clothing usually has functions such as shielding and decoration. In summer, clothing is usually required to have good light-shielding and UV-resistant properties. Thin fabrics usually do not have good light-shielding and UV-resistant properties. Although thick fabrics have good light-shielding effects, they will make clothing stuffy and airtight. The properties of clothing are usually determined by the fabrics used to make them. Therefore, existing woven fabrics have the problem of poor light-shielding effects. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a highly breathable and cool yarn fabric.

[0005] The above technical purpose of the utility model is achieved through the following technical scheme: the highly breathable and cool yarn fabric comprises an inner layer and an outer layer fixedly connected to each other, the outer layer comprises alternately arranged shading parts and flat parts, a plurality of air holes are opened on the shading parts along the thickness direction of the fabric, the inner layer comprises alternately arranged air permeable section one and air permeable section two, the weft yarn of the inner layer is set as the cool yarn, the warp yarn of the inner layer located at one air permeable section is set as the alkali-soluble yarn, and the warp yarn of the inner layer located at the second air permeable section is set as the air permeable yarn.

[0006] The utility model is further configured as follows: the cross-sectional shape of the light shielding portion is M-shaped, and a breathable cavity is formed between the light shielding portion and the inner layer.

[0007] The utility model is further configured as follows: the alkali-soluble yarn is formed by twisting polyester ultra-fine fibers.

[0008] The utility model is further configured as follows: the cool yarn is formed by twisting a first spandex fiber with a triangular cross-sectional shape.

[0009] The utility model is further configured as follows: the breathable yarn is formed by twisting the second spandex fiber with a cross-shaped cross section.

[0010] The utility model is further configured as follows: the outer layer is woven from reflective yarns.

[0011] The utility model is further configured as follows: the reflective yarn comprises a reflective yarn core and a light-absorbing coated yarn spirally arranged on the outer side thereof; the reflective yarn core is twisted by a third spandex fiber, and the light-absorbing coated yarn is twisted by bamboo charcoal fiber.

[0012] In summary, the utility model has the following beneficial effects:

[0013] The outer layer includes a shading portion and a flat portion that are alternately arranged, and a plurality of air holes are opened on the shading portion along the thickness direction of the fabric. By setting the air holes, it is ensured that the fabric as a whole has a stable air permeability effect. At the same time, the air holes are inclined relative to the fabric, and the air permeability channel formed is non-linear, thereby preventing light from entering the interior of the fabric. The inner layer includes an alternately arranged air permeable section one and an air permeable section two. The weft yarn of the inner layer is arranged as a cool yarn, and the stable light-shielding property of the cool yarn is utilized to ensure that the inner layer has a good light-shielding effect. The warp yarn of the inner layer located at the first air permeable section is arranged as an alkali-soluble yarn, and the warp yarn of the inner layer located at the second air permeable section is arranged as a breathable yarn. The cross-sectional shape of the shading portion is M-shaped, and a breathable cavity is formed between the shading portion and the inner layer. The alkali-soluble yarn in the air permeable section one is removed by utilizing the characteristic that the alkali-soluble yarn is easily soluble in alkaline solution. The position of the air permeable section one corresponds to the position of the air permeable cavity, thereby ensuring that the gas entering from the air hole can penetrate into the inner layer along the gap of the air permeable section one, thereby further enhancing the overall air permeability of the fabric.
