Description

Technical Field

[0001] This utility model relates to the field of yarn technology, and more specifically, to quick-drying yarn. Background Technology

[0002] Yarn is a product made by processing various textile fibers to a certain fineness. It can be woven into various clothing and accessories. Yarn is a thin, long thread-like material made of fibers or fiber mixtures, commonly used in handicrafts such as knitting, sewing, crochet, and weaving. Yarn can be made from many different types of fibers, including cotton, wool, linen, silk, and synthetic fibers. Depending on the fiber type and processing method, yarn can have different textures, colors, and properties. Yarn is usually classified into different grades according to its thickness, such as: coarse yarn, medium yarn, and fine yarn. Each grade of yarn is suitable for different uses; for example, coarse yarn is suitable for making heavy items such as sweaters and scarves, while fine yarn is suitable for making lightweight items such as tulle and lace.

[0003] Yarns made from chemical fibers are quick-drying and durable, but they also have poor moisture absorption. If fabrics are made from such yarns, the breathability and moisture absorption of the fabric are generally poor. In hot and humid environments, the heat generated by the human body cannot be effectively dissipated through the yarns in the fabric, resulting in a stuffy feeling and reduced comfort.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide quick-drying yarn to improve the overall breathability of the yarn.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: the quick-drying yarn includes a yarn body, which is formed by twisting multiple strands of breathable yarn together. The breathable yarn includes a core yarn and an outer wrapping yarn spirally wound around the outside of the core yarn. During the winding process, the outer wrapping yarn forms several flat sections and several raised sections by using low winding density and high winding density. The surface of the yarn body is provided with several moisture-wicking grooves, which are formed by adjacent raised sections and flat sections abutting each other.

[0007] The present invention is further configured such that: the cross-sectional size of the raised section is larger than the cross-sectional size of the flat section, and the winding density of the outer wrapping yarn on the raised section is greater than the winding density of the outer wrapping yarn on the flat section.

[0008] The present invention is further configured such that: the core yarn is made of multiple strands of spandex yarn, and the spandex yarn is made of several spandex filaments twisted together.

[0009] The present invention is further configured such that: the outer covering yarn is made of several cotton fibers and several nylon profiled fibers twisted together, and the cross section of the nylon profiled fibers is cross-shaped.

[0010] The present invention is further configured such that the blending ratio of the cotton fiber and the nylon profiled fiber is 1:2.

[0011] In summary, this utility model has the following beneficial effects: the raised sections on the breathable yarn abut against the flat or raised sections on adjacent breathable yarns, forming several moisture-wicking grooves on the end face of the yarn body. The formation of these moisture-wicking grooves can increase the surface area of ​​the yarn body, thereby increasing the contact area with air, accelerating moisture evaporation, and improving the quick-drying effect of the yarn body. Furthermore, the moisture-wicking grooves can make the yarn body more fluffy. When the raised sections on the breathable yarn form the yarn body, they create an uneven surface structure on the yarn body, which can reduce the contact area between the yarn body and the skin. The yarn body is also less likely to adhere to the skin after being wet. Attached Figure Description

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] Quick-drying yarn, such as Figure 1 and Figure 2 As shown, the yarn body 1 is made of multiple strands of breathable yarn 5 twisted together. The breathable yarn 5 includes a core yarn and an outer wrapping yarn spirally wound around the outside of the core yarn. During the winding process, the outer wrapping yarn forms several flat sections 2 and several raised sections 3 by using low winding density and high winding density. The surface of the yarn body 1 is provided with several moisture-wicking grooves 6. The moisture-wicking grooves 6 are formed by the abutment of adjacent raised sections 3 and flat sections 2. The several moisture-wicking grooves 6 on the yarn body 1 can increase the surface area of ​​the yarn body 1, and at the same time increase the bulkiness of the yarn body 1, which greatly increases its breathability and can quickly release the moisture generated by the skin.

[0018] like Figure 1 , Figure 2 and Figure 3As shown, the breathable yarn 5 includes a core yarn and an outer yarn. The core yarn is made by twisting multiple strands of spandex yarn 4 using a twisting machine. The spandex yarn 4 is made by twisting several spandex filaments using a twisting machine. The outer yarn is made by twisting several cotton fibers and several nylon profiled fibers using a twisting machine. The cross-section of the nylon profiled fibers is set to a cross shape. The cross-shaped cross-section can improve the bulkiness and breathability of the nylon profiled fibers. Combined with the good abrasion resistance of the nylon profiled fibers themselves and the porous, bulky, and breathable characteristics of cotton fibers, the outer yarn has good abrasion resistance and a certain breathability. Preferably, the blending ratio of cotton fibers and nylon profiled fibers is 1:2. By increasing the proportion of nylon profiled fibers, the abrasion resistance and quick-drying effect of the outer yarn are improved. Because the cross-shaped cross-section of the nylon profiled fibers has a certain breathability, adding a small amount of cotton fibers is sufficient. Cotton fibers are used to improve the softness, breathability, moisture absorption, and comfort of the outer yarn. The core yarn is introduced to the top of the hollow spindle of the spinning machine using a hollow spindle method. Then, the outer yarn is introduced into the front roller of the spinning machine and undergoes traction and twisting. The outer yarn forms a wrap around the outside of the core yarn. During the traction process, the rotation speed of the front roller, middle roller, or back roller is adjusted to change the wrapping density of the outer yarn. This creates a flat section 2 and a raised section 3 on the outside of the core yarn. The raised section 3 is the part with a higher wrapping density, and the flat section 2 is the part with a lower wrapping density. Therefore, the cross-sectional size of the raised section 3 is larger than that of the flat section 2. Due to the different wrapping densities, the raised section 3 with a higher wrapping density has better abrasion resistance, while the flat section 2 with a lower wrapping density has better air permeability and greater porosity.

[0019] like Figure 1 and Figure 2As shown, after obtaining the breathable yarn 5 through the spinning process, multiple strands of the breathable yarn 5 are fed into a twisting machine for twisting. The number of strands in the breathable yarn 5 is not limited here; it can be two or three strands. This is because when the number of single yarns twisted at one time is three or less, the ply structure is stable. Twisting four to five single yarns introduces instability, and twisting six or more single yarns will inevitably return to the stable state of three twists. Furthermore, the multiple strands of breathable yarn 5 are arranged in the same twist direction, resulting in stable twisting and a uniform and stable ply structure. Since the vertical cross-sectional area of ​​the raised section 3 on the breathable yarn 5 is larger than that of the flat section 2, when twisting the multiple strands of breathable yarn 5, the raised section 3 on the breathable yarn 5 will interact with the flat section 2 on the adjacent breathable yarn 5. The entire section 2 or the raised section 3 abuts against each other, forming several moisture-wicking grooves 6 on the end face of the yarn body 1. The formation of several moisture-wicking grooves 6 can increase the surface area of ​​the yarn body 1. By increasing the surface area of ​​the yarn body 1, the contact area with air is increased, the evaporation of moisture is accelerated, and the quick-drying effect of the yarn body 1 is improved. In addition, the moisture-wicking grooves 6 can make the yarn body 1 more fluffy and improve the breathability. When the raised section 3 on the breathable yarn 5 forms the yarn body 1, it makes the surface of the yarn body 1 present an uneven structure, which can reduce the contact area between the yarn body 1 and the skin. The yarn body 1 is not easy to stick to the skin after being wet, and the wearing comfort is better.

All technical solutions falling within the scope of this utility model's concept are protected.
