Description

Technical Field

[0001] This utility model relates to the field of textile technology, and more specifically, to a composite yarn. Background Technology

[0002] Yarn is a textile product made by twisting fibers to form a certain fineness. It is mainly divided into short fiber yarn and continuous filament, and is commonly used in the production of fabrics, ropes, threads, knitting, embroidery, and various clothing items.

[0003] However, to ensure the strength of the yarn, the twisted yarn is usually quite compact, which results in poor air circulation inside the yarn. Therefore, after the yarn absorbs water, its internal moisture dissipation speed is relatively poor, making it difficult for yarn products to dry after washing. When wearing yarn products, the absorbed sweat cannot be dissipated in time during exercise, affecting the performance and comfort of wearing them.

[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 a composite yarn that improves the moisture dissipation speed inside the yarn through a new structural design.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a composite yarn, including a yarn core, the peripheral wall of the yarn core is coated with a waterproof layer, the outer peripheral wall of the waterproof layer is spirally wound with a moisture-wicking yarn, the moisture-wicking yarn is arranged in an array with a plurality of support members along its length direction, the gap between the plurality of support members and the moisture-wicking yarn and the waterproof layer forms a ventilation space one, the peripheral wall of the plurality of support members is spirally wound with a moisture-dissipating yarn, the moisture absorption of the moisture-dissipating yarn is greater than that of the moisture-wicking yarn and the support members, the gap between the plurality of support members and the moisture-wicking yarn and the moisture-dissipating yarn forms a ventilation space two, the ventilation space one and the ventilation space two are interconnected.

[0007] The present invention is further configured such that: the yarn core is made by twisting multiple first strands of yarn in an "S" twisting manner, the first strands of yarn are made by twisting polyester shaped fibers with a cross-shaped cross section, and the waterproof layer is made of polyurethane coating.

[0008] The present invention is further configured such that: the moisture-wicking yarn includes a first strand and a second strand, the second strand being formed by twisting cotton fibers, and the moisture absorption of the second strand being greater than that of the first strand.

[0009] The present invention is further configured such that: the diameter of the support member is larger than the diameter of the moisture-wicking yarn, and the moisture-wicking yarn and the several support members are all made by winding the second strand of yarn around the first strand of yarn through a slub yarn spinning method.

[0010] The present invention is further configured such that: the winding direction of the moisture-wicking yarn is opposite to the winding direction of the moisture-dispersing yarn, the twist of the moisture-wicking yarn is set to 105 twists / 10cm, and the twist of the moisture-wicking yarn is set to 160 twists / 10cm.

[0011] The present invention is further configured such that: the moisture-wicking yarn is made by spirally winding a third strand around a first strand, the third strand being made by twisting flax fibers, and the moisture absorption of the third strand being greater than that of the second strand.

[0012] In summary, this utility model has the following beneficial effects: the waterproof layer effectively prevents the yarn core from contacting moisture, thus ensuring the dryness of the yarn core; by reducing the twist of the moisture-wicking yarn and the moisture-dissipating yarn and supporting it with several support members, the gaps inside the yarn are increased, so that the formed ventilation space one and ventilation space two can improve the air circulation effect between the inside and outside of the yarn, thereby increasing the moisture dissipation speed inside the yarn; the special porous structure of flax fiber allows the moisture-dissipating yarn to quickly disperse the moisture it absorbs; the design of the yarn with increasing hygroscopicity from the inside to the outside allows the moisture absorbed in the moisture-wicking yarn and several support members to be transferred to the moisture-dissipating yarn in time for rapid dissipation, further improving the moisture dissipation speed inside the yarn core.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Example: A composite yarn, such as Figures 1-4As shown, it includes a yarn core 1, which is formed by twisting two first strands 8 together using a twisting machine in an "S" twisting manner. The first strands 8 are formed by twisting polyester shaped fibers with a cross-shaped cross section using a twisting machine. Polyester fibers have high strength and abrasion resistance, making the yarn core 1 less prone to wear and breakage. The peripheral wall of the yarn core 1 is coated with a waterproof layer 2. This waterproof layer 2 is formed by impregnating the yarn core 1 with polyurethane coating and then drying it. Polyurethane coating has good waterproof properties, so the waterproof layer 2 can effectively limit the contact between the yarn core 1 and moisture, thereby maintaining the dryness of the yarn core 1.

[0020] like Figures 1-4 As shown, a moisture-wicking yarn 3 is spirally wound around the outer periphery of the waterproof layer 2 using a fancy twisting machine. Several support members 4 are arranged in an array along the length of the moisture-wicking yarn 3. The moisture-wicking yarn 3 includes a first strand 8 and a second strand 9. The moisture-wicking yarn 3 and the several support members 4 are all made by winding the second strand 9 onto the first strand 8 using a ring spinning machine in a slub yarn spinning manner. This ring spinning machine is controlled by a servo motor, which can precisely adjust the speed changes during the spinning process. By reducing the moving speed of the roller, the second strand 9 is wound multiple times in a designated area on the first strand 8, thereby forming a slub effect. By shaping the polyester fibers, the internal voids and surface area are increased, thereby improving the moisture dissipation of the first strand 8. The moisture absorption of cotton fibers is greater than that of polyester shaped fibers, so that the moisture absorbed in the first strand 8 located in the center of the moisture-wicking yarn 3 can be transferred to the second strand 9 on the outside in a timely manner. Cotton fibers have good moisture dissipation properties, thereby improving the drying speed inside the moisture-wicking yarn 3.

[0021] like Figures 1-4 As shown, cotton fibers have good softness. The moisture-wicking yarn 3 and several support members 4 formed by multiple windings of cotton fibers provide cushioning during yarn contact and friction, while also improving the yarn's softness. A moisture-dispersing yarn 6 is spirally wound around the periphery of each support member 4 using a fancy twisting machine. The winding direction of the moisture-wicking yarn 3 is opposite to that of the moisture-dispersing yarn 6. The yarn formed by the alternating winding of the moisture-wicking yarn 3 and the moisture-dispersing yarn 6 is less prone to loosening. The twist of the moisture-wicking yarn 3 is set to 105 twists / 10cm, and the twist of the support member 4 is set to 160 twists / 10cm. The diameter of the support member 4 is greater than... The diameter of the moisture-wicking yarn 3 is increased by reducing the twist of the moisture-wicking yarn 3 and the moisture-dispersing yarn 6 and by supporting them with several support members 4. This increases the gap inside the yarn, so that the gap between the support members 4 and the moisture-wicking yarn 3 and the waterproof layer 2 forms a ventilation space 1 5, and the gap between the support members 4 and the moisture-wicking yarn 3 and the moisture-dispersing yarn 6 forms a ventilation space 2 7. The ventilation space 1 5 and the ventilation space 2 7 are interconnected. The interconnected ventilation space 1 5 and ventilation space 2 7 can improve the air circulation effect between the inside and outside of the yarn, thereby improving the moisture dissipation speed and breathability inside the yarn.

[0022] like Figures 1-4 As shown, the moisture-wicking yarn 6 is made by spirally winding a third strand 10 onto a first strand 8 using a ring spinning machine. The third strand 10 is made by twisting flax fibers, which have stronger moisture absorption than cotton fibers. At the same time, due to its special porous structure, the flax fibers can quickly disperse the absorbed moisture, so that the moisture absorbed in the first strand 8 located in the center of the moisture-wicking yarn 6 can be transferred to the third strand 10 on the outside for rapid dissipation. Through the overall yarn with the moisture absorption increasing from the inside to the outside, the moisture absorbed in the moisture-wicking yarn 3 and several support members 4 can be transferred to the moisture-wicking yarn 6 for rapid dissipation, thereby further improving the moisture dissipation speed inside the yarn core 1, so that the finished yarn has a good quick-drying effect.

[0023] like Figures 1-4 As shown, when this type of composite yarn needs to be made, the two first strands 8 are first twisted together using a twisting machine to form a yarn core 1. Then, the yarn core 1 is impregnated with polyurethane coating and sent to a dryer to dry, forming a waterproof layer 2. The ring spinning machine then spirally winds a second strand 9 onto a first strand 8. During this process, the movement speed of the rollers is intermittently controlled so that the second strand 9 is wound multiple times in a designated area on the first strand 8 to form a moisture-wicking yarn 3 and several support members 4. The ring spinning machine then uniformly winds a third strand 10 onto a first strand 8 to form a moisture-dispersing yarn 6. Finally, a yarn core 1 coated with the waterproof layer 2, a moisture-wicking yarn 3, and a moisture-dispersing yarn 6 are simultaneously fed into a fancy twisting machine. The moisture-wicking yarn 3 and the moisture-dispersing yarn 6 are wound sequentially in opposite directions by two rollers, so that the moisture-wicking yarn 3 is wound onto the waterproof layer 2 and the moisture-dispersing yarn 6 is wound onto the moisture-wicking yarn 3, thus completing the production of this type of composite yarn.
