[0018] The utility model will be described in detail in combination with the drawings and examples.

[0019] A no hair fibre flannel yarn, such as Figure 1 , Figure 2 and Figure 3As shown, including the outermost hairless outer wrapping yarn 1 and the innermost high-elastic core yarn, the outer side of the high-elastic core yarn is spirally wrapped with the moisture-absorbing and air-permeable yarn 3, the wrapping density of the moisture-absorbing and air-permeable yarn 3 wrapped on the high-elastic core yarn is divided into a low wrapping density area and a high wrapping density area, the low wrapping density area and the high wrapping density area are alternately arranged, the exposure degree of the high-elastic core yarn in the low wrapping density area is higher than that of the high-elastic core yarn in the high wrapping density area, and the outer side of the moisture-absorbing and air-permeable yarn 3 is further wrapped with two fixed yarns 2, the hairless outer wrapping yarn 1 is spirally wrapped on the outer peripheral wall of the fixed yarn 2, and by setting different wrapping twists of the moisture-absorbing and air-permeable yarn 3, the low wrapping twist area forms a plurality of cavities between the hairless outer wrapping yarn 1 and the high-elastic core yarn, which improves the overall bulkiness and air permeability of the yarn to some extent, and the innermost high-elastic core yarn can participate in the moisture absorption and moisture dispersion effect of the yarn, and the high wrapping twist part provides protection for the high-elastic core yarn, and the high wrapping twist improves the firmness of the moisture-absorbing and air-permeable yarn 3 outside the high-elastic core yarn, the moisture-absorbing and air-permeable yarn 3 as the intermediate layer, its special spiral wrapping mode (low wrapping density area and high wrapping density area are alternately arranged) not only ensures the air permeability of the yarn, but also optimizes the moisture absorption performance by adjusting the wrapping density, in the low wrapping density area, the high-elastic core yarn has a higher exposure degree, which is helpful for the rapid discharge of sweat and moisture, and in the high wrapping density area, the close wrapping of the moisture-absorbing and air-permeable yarn 3 enhances the moisture absorption performance of the yarn, so that the yarn can not only keep dry, but also effectively absorb and disperse sweat, and the fixed yarn 2 outside the moisture-absorbing and air-permeable yarn 3 is mainly to improve the strength between the moisture-absorbing and air-permeable yarn 3 and the high-elastic core yarn, and the hairless outer wrapping yarn 1 is in contact with the fixed yarn 2 during wrapping, forming a plurality of gaps in the yarn, further improving the overall bulkiness and porosity of the yarn.

[0020] As shown in Figure 1 , Figure 2 and Figure 3 , first, prepare the high-elastic core yarn, the high-elastic core yarn is twisted by a plurality of spandex fiber yarns 4, which ensures that the core has excellent elasticity and recovery, and the selection of spandex fiber and the twisting process can be adjusted according to specific needs to obtain the required high elasticity and durability, preferably, the number of spandex fiber yarns 4 is three, and the high-elastic core yarn is obtained by twisting the three spandex fiber yarns 4 by a twisting machine, and the high-elastic core yarn formed by three-twisted has the characteristics of stable yarn structure and is not easy to produce shedding.

[0021] As shown in Figure 1 , Figure 2 and Figure 3 , then, spirally wrap the moisture-absorbing and air-permeable yarn 3 outside the high-elastic core yarn, the moisture-absorbing and air-permeable yarn 3 is twisted by viscose fiber and ramie fiber, the combination of the two fibers makes the yarn have excellent moisture absorption, air permeability, antibacterial and anti-mite properties, toughness and wear resistance.

[0022] As shown in Figure 1 ,Figure 2 and Figure 3 As shown in the drawings, when the moisture-permeable and moisture-absorbable yarn 3 is wrapped, the speed of the hollow spindle of the hollow spindle covering machine, the yarn leading speed, the winding speed and the like can be directly input and set by the touch screen. When the low wrapping density area is formed, the winding speed and the yarn leading speed are reduced, and when the high wrapping density area is formed, the yarn leading speed and the winding speed are increased, so that the length of the moisture-permeable and moisture-absorbable yarn 3 in the high wrapping density area is 5-10 times the length of the moisture-permeable and moisture-absorbable yarn 3 in the low wrapping density area, and the length of the high wrapping density area is 2-3 times the length of the low wrapping density area. The length of the high wrapping density area is divided into a low wrapping density area and a high wrapping density area. In the low wrapping density area, the moisture-permeable and moisture-absorbable yarn 3 is wrapped relatively sparsely, so that the high-elasticity core yarn has a relatively high degree of exposure. In the high wrapping density area, the moisture-permeable and moisture-absorbable yarn 3 is wrapped relatively tightly, so that the high-elasticity core yarn has a relatively low degree of exposure. The alternating wrapping density areas ensure the overall elasticity of the yarn and increase the air permeability and moisture absorption of the yarn.

[0023] As shown in the drawings, Figure 1 , Figure 2 and Figure 3 On the outside of the moisture-permeable and moisture-absorbable yarn 3, two fixed yarns 2 are also wrapped. The fixed yarns 2 help to further fix the structure of the yarn, improve its stability and durability. The fixed yarns 2 are selected from nylon yarns. Nylon has good wear resistance and wrinkle resistance, and is suitable for making textiles that need to maintain their shape. The wrapping direction of the fixed yarns 2 is opposite to the wrapping direction of the moisture-permeable and moisture-absorbable yarn 3. This reverse wrapping helps to increase the overall tightness and stability of the yarn.

[0024] As shown in the drawings, Figure 1 , Figure 2 and Figure 3 Finally, a non-lint outer wrapping yarn 1 is spirally wrapped on the outermost side. The non-lint outer wrapping yarn 1 is twisted from viscose fibers and cotton fibers. The combination of these two fibers makes the yarn have a soft hand feel and good moisture absorption. The average yarn loop spacing of the non-lint outer wrapping yarn 1 is 0.5-1mm. This tight wrapping method helps to further improve the overall strength and stability of the yarn. The average yarn loop spacing of the non-lint outer wrapping yarn 1 forms several small grooves on the surface of the yarn, allowing external air to enter the interior of the yarn through the grooves, so that the moisture-permeable and moisture-absorbable yarn 3 inside the yarn can function.

[0025] As shown in the drawings, Figure 1 , Figure 2 and Figure 3 The wrapping operation of the non-lint fiber yarn is wrapped and formed by a hollow spindle covering machine. The high-elasticity core yarn, the non-lint outer wrapping yarn 1, the moisture-permeable and moisture-absorbable yarn 3 and the fixed yarn 2 are all twisted by a twisting machine.

[0026] The above merely is preferred implementation manner of the present application, the protection scope of the present application is not only limited to the above examples, and belongs to the technical scheme under the idea of the present application all belongs to the protection scope of the present application. It should be pointed out that, for ordinary skilled person in the art, under the premise of not departing from the principle of the present application, some improvements and decorations, these improvements and decorations should also be considered as the protection scope of the present application.
