[0002] The current textile field mainly relies on finishing process to improve the moisture absorption and ventilation performance of fabric, such as achieving functional improvement through chemical coating or auxiliary agent impregnation, etc. However, such processing methods have obvious defects, i.e. the functional components are prone to fall off or degrade after multiple washes or long-term use, resulting in performance attenuation and difficulty in stable maintenance.

[0003] In the prior art, there are also attempts to use profiled cross-section fibers to make yarns to improve ventilation, such as Y-shaped, cross-shaped, etc. The inter-fiber space is formed through structural design to achieve ventilation and moisture absorption effect, but the geometric shape of the fiber is relatively simple, and after the yarn is processed and formed, the fibers are easily tightly attached to each other, so the actual formed micro-pore structure has significant fluctuations in size, distribution density and continuity, which cannot ensure the support for ventilation effect, especially in high humidity or mechanical stress environment, the dynamic deformation between fibers will further compress the inter-fiber space, making it difficult to guarantee stable and sufficient ventilation channels. Therefore, in order to solve this problem, a new scheme needs to be proposed. SUMMARY

[0004] The utility model aims at solving the above-mentioned problems and provides a kind of moisture-absorbing quick-drying yarns and fabrics.

[0006] Preferably, the width of the U-shaped ventilation space is greater than the width of the two end edges.

[0007] Preferably, the width of the V-shaped ventilation space is greater than the width of one end edge.

[0008] Preferably, the X-shaped cross-section fiber filaments on the yarn body are uniformly arranged, and the end edges of adjacent X-shaped cross-section fiber filaments are embedded into the U-shaped ventilation space.

[0009] Preferably, the X-shaped cross-section fiber filaments on the yarn body are uniformly arranged, and the end edges of adjacent X-shaped cross-section fiber filaments are tightly aligned with each other.

[0010] Preferably, the X-shaped cross-section fiber filaments on the yarn body are randomly arranged.

[0011] A moisture absorption and quick-drying fabric is woven by moisture absorption and quick-drying yarns.

[0012] Compared with the prior art, the moisture absorption and quick-drying fabric has the advantages that:

[0013] Through the symmetrical cross-arc edge design of the X-shaped cross-section fiber yarn, the U-shaped and V-shaped ventilation spaces formed are more stable in yarn processing and use, the structure can reduce excessive adhesion between fibers, ensure that a ventilation and moisture absorption channel meeting the requirements can be formed on the yarn, and the structure has good mechanical support, so that the ventilation channel still has a lasting effect under high humidity or mechanical stress, solves the problem that the traditional special-shaped fiber is easily affected by external force and causes ventilation attenuation, and different aperture ventilation channels formed in the U-shaped and V-shaped ventilation spaces can also cope with the flow and discharge of moisture and liquid at the same time, and the moisture absorption and sweat discharge efficiency is improved.

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and it should be understood in the description of the utility model that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and are not intended to indicate or imply that the devices or elements indicated must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the utility model, obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] A moisture absorption and quick-drying yarn, as shown in Figures 1-4 The yarn body 1 is twisted by a plurality of X-shaped cross-section fiber filaments 2, and the cross section of the X-shaped cross-section fiber filament 2 is composed of four horizontal parallel end edges 3 and a central symmetrically intersecting arc edge 4. The U-shaped ventilation space 5 is formed between the left and right sides of the X-shaped cross-section fiber filament 2, i.e., between the arc edge 4 and the end edge 3, and the width of the U-shaped ventilation space 5 is greater than the width of the two end edges 3. Therefore, the U-shaped ventilation space 5 still has additional ventilation space while accommodating the two end edges 3. The V-shaped ventilation space 6 is formed between the upper and lower sides of the X-shaped cross-section fiber filament 2, i.e., between the arc edges 4, and the width of the V-shaped ventilation space 6 is greater than the width of one end edge 3. Therefore, the V-shaped ventilation space 6 can accommodate the embedding of one end edge 3 and has additional ventilation space.

[0021] Therefore, in the moisture absorption and quick-drying yarn, no matter what arrangement method is used to twist the X-shaped cross-section fiber filaments 2, the adjacent fiber filaments cannot be closely fitted, and effective ventilation channels are formed in the U-shaped ventilation space 5 and the V-shaped ventilation space 6. Since there are two end edges 3 in parallel on one side, the structure also has good mechanical support effect. The ventilation channels still have a lasting effect under high humidity or mechanical stress, avoiding the problem that traditional special-shaped fibers are easily affected by external forces and cause ventilation to decay. At the same time, the ventilation channels of different pore sizes formed in the U-shaped ventilation space 5 and the V-shaped ventilation space 6 can also cope with the flow and discharge of moisture and liquid, improving the moisture absorption and sweat discharge efficiency.

[0022] Example One

[0023] A moisture absorption and quick-drying fabric is woven from a moisture absorption and quick-drying yarn, as shown in Figure 2 The moisture absorption and quick-drying yarn is twisted by a plurality of X-shaped cross-section fiber filaments 2, and the X-shaped cross-section fiber filaments 2 on the yarn body 1 are uniformly arranged, and the end edges 3 of adjacent X-shaped cross-section fiber filaments 2 are embedded into the U-shaped ventilation space 5. In this embodiment, there are more X-shaped cross-section fiber filaments 2 in the same yarn radius, and stable and dense small-pore ventilation channels are formed between the fiber filaments, which can form more siphon channels. Therefore, the yarn and fabric of this embodiment have higher strength, good ventilation, and better moisture guiding effect, but this embodiment requires more precise multi-axial twisting devices and multiple manufacturing processes, and the production cost is higher.

[0024] Example Two

[0025] A moisture absorption and quick-drying fabric is woven from a moisture absorption and quick-drying yarn, as shown in Figure 3As shown, the moisture-wicking and quick-drying yarn is formed by twisting several X-shaped cross-section fiber filaments 2, and the X-shaped cross-section fiber filaments 2 on the yarn body 1 are evenly arranged, with the ends 3 of adjacent X-shaped cross-section fiber filaments 2 closely aligned with each other. In this embodiment, within the same yarn radius, several largest air-permeable channels and some small air-permeable channels can be formed simultaneously. Therefore, the yarn and fabric of this embodiment have higher air permeability and good moisture-wicking performance. However, this embodiment also requires a relatively precise multi-axial twisting device and various manufacturing processes to achieve. Moreover, compared with Embodiment 1, this embodiment also requires fiber bonding technology to enhance stability and strength, and the production cost is also higher.

[0026] Example 3

[0027] A moisture-wicking and quick-drying fabric, woven from moisture-wicking and quick-drying yarns, such as... Figure 4 As shown, the X-shaped cross-section fiber filaments 2 on the yarn body 1 are randomly arranged. In this embodiment, the number of X-shaped cross-section fiber filaments 2 is moderate within the same yarn radius. Due to the disordered arrangement, several breathable channels with different apertures and shapes will be formed on them. Nevertheless, the number and size of the breathable channels can meet the daily needs for breathability and moisture wicking performance. Moreover, the ends 3 of the X-shaped cross-section fiber filaments 2 in each direction will press against each other, thus forming a stable structure. Since the X-shaped cross-section fiber filaments 2 are twisted and polymerized from all directions, the elastic deformation effect of the yarn in multiple directions will be more outstanding. Most importantly, the production of this yarn does not require precision equipment and complex processes, only simple twisting. At the same time, the breathability and moisture wicking performance of the produced yarn can meet daily needs, making it suitable for mass production.
