[0019] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.
[0020] Embodiment: The light-shielding sun-proof polyester yarn, such as Figure 1-Figure 4 As shown, it includes a breathable yarn core 1, the breathable yarn core 1 includes a shading yarn 3 and a supporting yarn 2. The breathable yarn core 1 is made by spirally winding the shading yarn 3 on the peripheral wall of the supporting yarn 2 through a ring spinning process. Five hygroscopic yarns 5 are arranged in a circular array on the peripheral wall of the shading yarn 3 away from the supporting yarn 2. While the five hygroscopic yarns 5 and the breathable yarn core 1 are conveyed together, a shading yarn 2 7 is spirally wound on the peripheral wall of the five hygroscopic yarns 5 away from the breathable yarn core 1 through a ring spinning process, so that the axes of the five hygroscopic yarns 5 are all arranged parallel to the axis of the breathable yarn core 1, and the required yarn is made by tightly abutting the five hygroscopic yarns 5 against the breathable yarn core 1 and the shading yarn 2 7.
[0021] like Figure 1-Figure 4 As shown, the hygroscopic yarn 5 is formed by twisting wool fibers through a twisting machine. The wool fibers have good hygroscopic effects. By adding five strands of hygroscopic yarn 5, the yarn can absorb sweat produced by the skin in time when in contact with the skin. The supporting yarn 2 is twisted by a twisting machine. The shading yarn 1 3 and the shading yarn 2 7 are both twisted by twisting polyester shaped fibers with triangular cross-sections through a twisting machine. The acid resistance of wool fibers is greater than that of cotton fibers, and the acid resistance of polyester shaped fibers is greater than that of wool fibers. After the prepared yarn is acid-lyzed to remove the supporting yarn 2 through a burn-out process, a breathable cavity 4 is formed inside the breathable yarn core 1. The acid-lysis concentration of the solution during the burn-out process is greater than the acid resistance of the cotton fibers and less than the acid resistance of the wool fibers, so as to avoid damage to the hygroscopic yarn 5, the shading yarn 1 3 and the shading yarn 2 7 after the burn-out process.
[0022] like Figure 3 As shown, the air cavity 4 increases the surface area and air permeability of the yarn, and the polyester shaped fiber with a triangular cross-section is spun through a spinneret. The polyester shaped fiber has a good shading effect, so that the manufactured shading yarn 3 and shading yarn 2 7 can effectively block the penetration of sunlight. The spirally coated shading yarn 3 and shading yarn 2 7 form two shading layers on the yarn, and the triangular cross-section of the polyester shaped fiber increases the internal gap, so that the shading yarn 3 and shading yarn 2 7 have certain moisture absorption and air permeability. At the same time, the triangular cross-section increases the glossiness of the polyester shaped fiber, so that the shading yarn 3 and shading yarn 2 7 can reflect most of the sunlight, further improving the sun protection effect of the yarn.
[0023] like Figure 2 and Figure 3As shown, five breathable spaces 6 are set up between five adjacent hygroscopic yarns 5, and the five breathable spaces 6 are interconnected with the breathable cavity 4. The twist of the shading yarn 3 is 240 twists / 10cm, and the twist of the shading yarn 3 and the shading yarn 2 7 is the same. While ensuring the strength of the yarn, a certain gap exists between two adjacent twists of the shading yarn 3 and the shading yarn 2 7 after twisting, so that the shading yarn 3 forms a thread-shaped ventilation groove 8 after being coated and twisted, and the shading yarn 2 7 forms a thread-shaped ventilation groove 2 9 after being coated and twisted.
[0024] like Figure 2 and Figure 3 As shown, the ventilation groove 1 8 is interconnected with the ventilation cavity 4 and the ventilation space 6 at the same time, and the ventilation groove 2 9 is interconnected with the ventilation space 6, so that the ventilation cavity 4, the plurality of ventilation spaces 6, the ventilation groove 1 8 and the ventilation groove 2 9 can be interconnected. The interconnected ventilation cavity 4, the plurality of ventilation spaces 6, the ventilation groove 1 8 and the ventilation groove 2 9 allow good air circulation in the yarn, can promptly remove the moisture absorbed in the yarn, thereby improving the overall air permeability of the yarn and avoiding the stuffiness of the manufactured clothing when worn.
[0025] like Figure 1-Figure 4 As shown, since the shade yarn 1 3 and the shade yarn 2 7 have the same twist, the widths of the ventilation groove 1 8 and the ventilation groove 2 9 are the same, and the twisting directions of the shade yarn 1 3 and the shade yarn 2 7 are the same, so that the ventilation groove 1 8 and the ventilation groove 2 9 are staggered along the length direction of the breathable yarn core 1, and the staggered ventilation grooves 1 8 and the ventilation grooves 2 9 prevent sunlight from directly penetrating the yarn. Through a plurality of breathable spaces 6, breathable cavities 4, ventilation grooves 1 8 and ventilation grooves 2 9, the sunlight entering the yarn can be dispersed, thereby weakening the intensity of sunlight entering the yarn, so that the manufactured fabric has good sun protection and breathable effects.
[0026] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
