In recent years, with the development of the domestic consumer market, there are more and more yarn products with different styles, and the market for fancy yarns is also growing. Fancy yarns have attracted much attention due to their distinctive characteristics.

[0003] In order to improve the performance of yarn, multiple fiber blends are usually used to make yarn, and the different characteristics of different fibers are combined to make the yarn have multiple characteristics. For example, spandex fiber, nylon fiber and cotton fiber are blended to make the yarn have the elasticity and durability of spandex and the wear resistance of nylon yarn, while maintaining the breathability and comfort of cotton. The strength of the effect varies depending on the blending ratio. Therefore, a high-density spandex core elastic thread is set to ensure that the yarn has good air permeability while having good elasticity, wear resistance and breathability.

[0018] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] A high-density spandex core elastic thread, such as Figure 1 and Figure 2As shown, it includes a yarn body 1, the yarn body 1 includes a high-elastic yarn 2, the high-elastic yarn 2 includes a flat portion 21 and a raised portion 22, the flat portion 21 and the raised portion 22 are alternately arranged, the diameter of the raised portion 22 is larger than the diameter of the flat portion 21, the outer side of the high-elastic yarn 2 is spirally wound with a breathable yarn 3, and a breathable cavity 10 is arranged on the raised portion 22, the breathable cavity 10 is formed by rottenly forming the raised portion 22, the high-elastic yarn 2 on the raised portion 22 is away from the breathable yarn 3 to form the breathable cavity 10, part of the yarn body 1 is raised, the roughness of the yarn surface is increased to improve the durability of the yarn body 1, and the breathable cavity 10 formed between the high-elastic yarn 2 and the breathable yarn 3 can improve the ventilation effect of the yarn body 1, while ensuring that the yarn body 1 has good strength, elasticity and durability while also having good breathability.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the high-elastic yarn 2 is set as a knotty fancy yarn, and the high-elastic yarn 2 is twisted by a composite yarn 2 4. A number of spandex fibers and a number of cotton fibers are taken and put into a twisting machine for twisting to obtain a core yarn 5 and a covering yarn 6, and the core yarn 5 and the covering yarn 6 are fed into a mule spinning machine. The covering yarn 6 is spirally wound on the outside of the core yarn 5 through the mule spinning process to obtain the composite yarn 2 4. The excellent elasticity and softness of the spandex fiber are utilized, combined with the porous, fluffy and soft characteristics of the cotton fiber, to ensure that the composite yarn 2 has good yarn elasticity and good air permeability. The composite yarn 2 is fed into a device for manufacturing knotty fancy yarns to obtain a high-elastic yarn 2 with a number of nodules on the yarn. The nodules of the knotty fancy yarn have a larger diameter-to-length ratio than the nodules of the bamboo fancy yarn. Preferably, the number of strands of the composite yarn 2 fed into the device for manufacturing the separated fancy yarn can be multiple strands, which can enhance the yarn strength of the high-elastic yarn 2 and have larger nodules, so as to facilitate the formation of a larger air permeability cavity 10 in the yarn body 1.

[0021] like Figure 1 , Figure 2 and Figure 4 As shown, the breathable yarn 3 is formed by twisting a plurality of composite yarns 7, and a plurality of cotton fibers and a plurality of nylon shaped fibers are respectively put into a twisting machine for twisting to obtain a first strand 8 and a second strand 9, and the first strand 8 and the second strand 9 are fed into the twisting machine for twisting to obtain a composite yarn 7, wherein the cross section of the nylon shaped fiber is set to be an equilateral triangle, and the cross section of the equilateral triangle can make the nylon shaped fiber have good gloss and good bending resistance and wear resistance, and the plurality of composite yarns 7 are fed into the twisting machine for twisting to obtain the breathable yarn 3, and the number of strands of the composite yarn 7 is equal to three strands, and the three-strand twisting can make the breathable yarn 3 have good structural strength, thereby improving the strength of the breathable yarn 3.

[0022] like Figure 1 , Figure 2 and Figure 3As shown, the high-elastic yarn 2 and the breathable yarn 3 are fed into the mule spinning machine, and the breathable yarn 3 is spirally wound on the outside of the high-elastic yarn 2 through the mule spinning process. Since the high-elastic yarn 2 has a plurality of nodules, the yarn body 1 also has a flat portion 21 and a convex portion 22. The twist of the breathable yarn 3 is Z twist, which has better strength and wear resistance, and the outer wrapping twist of the breathable yarn 3 is 150 twists / m. The setting of the twist number can make the breathable yarn 3 better cover the high-elastic yarn 2 and reduce the possibility of the high-elastic yarn 2 falling off. Since the high-elastic yarn 2 has a plurality of nodules, the twist of the breathable yarn 3 at its nodules is greater than that of the high-elastic yarn 2 when it is covered. The twist of the flat part 21 of the elastic yarn 2 allows the breathable yarn 3 to better cover the nodules of the high-elastic yarn 2. The acidic slurry is applied to the raised part 22 of the yarn body 1. The acidic slurry penetrates and contacts the nodules of the high-elastic yarn 2. The acidic slurry alkali-corrodes the cotton fiber with poor acid resistance and retains the spandex fiber with good acid resistance. The yarn thickness of the alkali-corroded part of the high-elastic yarn 2 becomes thinner, its nodules become smaller, and the inside becomes more fluffy, and a breathable cavity 10 is formed between the high-elastic yarn 2 and the breathable yarn 3, which improves the breathability of the yarn body 1 and still has a certain convex effect, so that the yarn body 1 has good wear resistance and durability.

[0023] 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.
