AI Technical Summary
Existing environmentally friendly yarns have poor air permeability, especially when the major axis of the ellipse of a single strand is nearly perpendicular to the minor axis of the ellipse of the adjacent single strand, the area of the air pores decreases, resulting in insufficient air permeability.
It uses at least two single strands with an elliptical cross-section and different twists. The low-twist and high-twist yarns are spirally intertwined to form an environmentally friendly yarn. By utilizing the differences in twist and twisting direction, air-permeable gaps are formed, and the air-permeable gap area is increased by the close contact of the support area, thereby improving the air permeability efficiency.
It enhances the breathability of the environmentally friendly yarn, maintains the stability and toughness of the yarn, and ensures breathability for long-term use.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of yarn technology, specifically to a breathable and environmentally friendly yarn. Background Technology
[0002] Eco-friendly yarn refers to yarn that has minimal environmental impact during production, is sustainably produced, or is biodegradable. These yarns typically use environmentally friendly materials and production processes, reducing pollution and resource consumption.
[0003] Existing environmentally friendly yarns are subject to material selection restrictions depending on environmental requirements. The materials used affect the overall breathability of the environmentally friendly yarn, resulting in a technical problem where the yarn is highly environmentally friendly but has poor breathability.
[0004] Chinese utility model patent with authorization announcement number CN213037917U: A breathable polyester environmentally friendly yarn, which discloses a technical solution to enhance the breathability of the environmentally friendly yarn by using a single strand with an elliptical cross section.
[0005] Although the aforementioned utility model patent has made some progress in the technical solution of enhancing breathability, when the major axis of the ellipse of a single strand is nearly perpendicular to the minor axis of the ellipse of the adjacent single strand, the area of the breathable holes will be greatly reduced. Therefore, the breathability of the existing environmentally friendly yarn is poor. There is an urgent need in the field for an environmentally friendly yarn with good breathability to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a breathable and environmentally friendly yarn to solve the technical problem of poor breathability of existing environmentally friendly yarns.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a breathable and environmentally friendly yarn, comprising at least two single strands, all of which have different twists; the cross-section of each single strand is elliptical; the environmentally friendly yarn is formed by spirally winding and twisting all the single strands together.
[0008] One single strand is a low-twist yarn, and the other is a high-twist yarn. The area on the outer surface of the low-twist yarn that is in close contact with the high-twist yarn is the first support area, and the area on the outer surface of the high-twist yarn that is in close contact with the low-twist yarn is the second support area. The first and second support areas are in close contact with each other. The first support area is located at the end of the major axis of the elliptical cross-section of the low-twist yarn, and the second support area is located at the end of the major axis of the elliptical cross-section of the high-twist yarn. The mutual support between the major axes creates several air-permeable gaps between the low-twist and high-twist yarns, improving the air permeability of the yarn. Furthermore, combined with the different twists between the single strands, the area of each air-permeable gap can be increased, further improving the air permeability efficiency of the air-permeable gap.
[0009] As a preferred option, the twisting direction of one single strand is opposite to that of other single strands, which can prevent the spiral concave surfaces between the single strands from being filled with each other, and further improve the air permeability of the environmentally friendly yarn.
[0010] As a preferred option, the environmentally friendly yarn is formed by spirally winding and twisting single strands of at least two materials, including organic cotton, recycled cotton, flax, ramie, silk, wool, bamboo fiber, Tencel, and Modal.
[0011] As a preferred option, the eco-friendly yarn is composed of single-ply yarn made of recycled cotton and single-ply yarn made of linen, which can improve the breathability of the eco-friendly yarn while ensuring its toughness.
[0012] As a preferred option, the eco-friendly yarn consists of three single strands of recycled cotton. While ensuring environmental protection, the oval-shaped single strand structure enhances the overall breathability of the eco-friendly yarn.
[0013] Beneficial effects:
[0014] 1. This solution uses single strands of yarn with an elliptical cross-section to form environmentally friendly yarn, which can create breathable gaps and enhance the breathability of the environmentally friendly yarn.
[0015] 2. This solution further utilizes the twist difference between different single strands to reduce the probability of the air gap being filled, thereby further improving the air permeability of the environmentally friendly yarn.
[0016] 3. This solution further utilizes single strands with different self-twisting directions to achieve interlocking of spiral trajectories, improving the stability of the air permeability gap and enabling the environmentally friendly yarn to maintain strong air permeability after long-term use.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0023] like Figures 1-2 As shown, the breathable and environmentally friendly yarn provided in this embodiment of the present invention includes at least two single strands, all of which have different twists; the cross-section of the single strand is elliptical; the environmentally friendly yarn is formed by spirally winding and twisting all the single strands together.
[0024] One single strand is a low-twist yarn 101, and the other is a high-twist yarn 201. The area on the outer surface of the low-twist yarn 101 that is in close contact with the high-twist yarn 201 is the first support area 102, and the area on the outer surface of the high-twist yarn 201 that is in close contact with the low-twist yarn 101 is the second support area 202. The first support area 102 and the second support area 202 are in close contact with each other. The first support area 102 is located at the end of the major axis of the elliptical cross-section of the low-twist yarn 101, and the second support area 202 is located at the end of the major axis of the elliptical cross-section of the high-twist yarn 201. The mutual support between the major axes creates several air-permeable gaps 301 between the low-twist yarn 101 and the high-twist yarn 201, improving the air permeability of the yarn. Furthermore, in conjunction with the different twists between the single strands, the area of a single air-permeable gap 301 can be increased, further improving the air permeability efficiency of the air-permeable gap 301.
[0025] The eco-friendly yarn is composed of single-ply yarn made of recycled cotton and single-ply yarn made of linen. The materials used improve the breathability of the eco-friendly yarn while ensuring its toughness. The twisting direction of the recycled cotton single-ply yarn is opposite to that of the linen single-ply yarn, which prevents the spiral concave surfaces between the single-ply yarns from being filled with each other, further improving the breathability of the eco-friendly yarn.
[0026] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
