Description

Technical Field

[0001] This utility model relates to the field of textile fabric technology, and in particular to a unidirectional water-wicking, quick-drying casual sports training fabric. Background Technology

[0002] During recreational sports training, the body's metabolic rate increases significantly, resulting in a large amount of sweat. As the medium through which the body directly contacts the external environment, the clothing fabric's ability to handle sweat directly affects the wearer's comfort and exercise experience. If the fabric cannot effectively and promptly absorb sweat, it will accumulate on the inside, causing a noticeable sticky feeling. This not only reduces comfort during exercise but may also increase the risk of catching a cold when body temperature drops after exercise, as sweat remains on the skin for an extended period, potentially impacting the athlete's health.

[0003] The current market offers a wide variety of sports fabrics, and while some possess certain moisture-wicking properties, they still have significant shortcomings in practical applications. On one hand, most fabrics have poor drying properties after absorbing moisture, making it difficult for sweat to evaporate quickly, resulting in the fabric remaining damp for extended periods and failing to meet the need for a dry feel during exercise. On the other hand, existing fabrics generally lack an effective one-way moisture-wicking mechanism, allowing sweat to repeatedly penetrate between the inner and outer surfaces of the fabric, failing to achieve the ideal effect of rapid moisture absorption and drying on the inner side and rapid evaporation on the outer side, thus failing to solve the core problem of sweat retention during exercise.

[0004] More importantly, existing sports fabrics often struggle to balance functionality and comfort. Many fabrics designed to improve water wicking use coarser fibers or tighter weaves, which, while enhancing water wicking, sacrifice softness and breathability. These fabrics can cause friction and discomfort against the skin, and their tight structure hinders airflow, exacerbating stuffiness. They fail to meet the high comfort requirements of casual sports settings and are ill-suited to athletes' dual needs for functionality and comfort.

[0005] With the continuous development of the leisure sports industry, consumers' performance requirements for sportswear have upgraded from basic clothing needs to a composite demand for efficient functionality and comfortable experience. Existing sports fabrics suffer from technical defects such as poor one-way water wicking, poor drying properties after moisture absorption, and an imbalance between functionality and comfort. Therefore, developing a fabric that can efficiently handle the entire process of sweat absorption, directional transport, and rapid evaporation, ensuring the inner side of the fabric remains dry at all times, while also possessing excellent breathability and a soft, skin-friendly feel, suitable for leisure sports training scenarios, has become a pressing technical problem to be solved in the textile industry. Utility Model Content

[0006] In view of the shortcomings of existing sports fabrics, such as poor one-way water wicking, poor dryness after moisture absorption, and difficulty in balancing functionality and comfort, the purpose of this utility model is to provide a one-way water-wicking and dry casual sports training fabric. This fabric can achieve rapid moisture absorption, directional transmission and efficient evaporation of sweat, ensuring that the inside remains dry at all times, while also having excellent breathability and softness, thus balancing sports functionality and casual wearing comfort.

[0007] The technical solution adopted in this utility model is as follows: it includes a three-layer composite structure, consisting of a skin-friendly and moisture-wicking inner layer, a one-way hydrophobic middle layer, and a fast-evaporating outer layer, from the inner side closest to the skin to the outer side. The three-layer composite structure is fixedly connected by a hot melt adhesive dot bonding process. The skin-friendly and moisture-wicking inner layer is a cotton-polyester blended plain weave fabric with a brushed surface. The one-way hydrophobic middle layer is a perforated fabric formed by interweaving irregularly shaped polyester fibers and polyamide fibers. The side of the one-way hydrophobic middle layer closest to the skin-friendly and moisture-wicking inner layer is treated with a hydrophilic finishing agent, and the side closest to the fast-evaporating outer layer is treated with a hydrophobic finishing agent. The fast-evaporating outer layer is a twill fabric woven from ultra-fine polyester fibers and is treated with antistatic and anti-UV finishing.

[0008] Preferably, the fineness of the blended yarn of the skin-friendly and moisture-wicking inner layer is 32S-40S, the twist is 800-1000 twists / meter, and it is woven using ring spinning technology. The warp density of the skin-friendly and moisture-wicking inner layer is 380-420 threads / 10cm, the weft density is 320-360 threads / 10cm, and the weight of the resulting cotton-polyester blended plain weave fabric is 80-100g / ㎡.

[0009] Preferably, the warp yarn of the unidirectional water-guided intermediate layer is a trilobal cross-section polyester fiber with a fineness of 75D / 36F, and the weft yarn is nylon 66 fiber with a fineness of 50D / 24F. The warp density of the unidirectional water-guided intermediate layer is 450-500 threads / 10cm, the weft density is 380-420 threads / 10cm, and the weight of the perforated fabric formed is 100-120g / ㎡.

[0010] Preferably, the hydrophilic finishing agent used in the unidirectional hydrophilic intermediate layer is a polyethylene glycol-type hydrophilic finishing agent, and the contact angle on one side after treatment with the hydrophilic finishing agent is ≤30°; the hydrophobic finishing agent is an organosilane-based hydrophobic finishing agent, and the contact angle on one side after treatment with the hydrophobic finishing agent is ≥120°.

[0011] Preferably, the ultrafine polyester fiber of the rapidly evaporating outer layer has a fineness of 50D / 72F and a dumbbell-shaped fiber cross-section. The warp density of the rapidly evaporating outer layer is 350-380 threads / 10cm, the weft density is 300-330 threads / 10cm, and the weight of the twill fabric formed is 70-90g / ㎡.

[0012] Preferably, the antistatic finishing of the rapid evaporation outer layer meets the Class A requirements of GB / T 12703.1-2008, and the UV-resistant finishing meets the UPF 30+ requirements.

[0013] Preferably, the hot melt adhesive used in the hot melt adhesive dot lamination process is low-melting-point polyamide granules, with a dot diameter of 0.3-0.5 mm, a dot spacing of 5-8 mm, a lamination temperature of 120-140℃, and a lamination pressure of 0.3-0.5 MPa.

[0014] The beneficial effects of this invention are as follows: A closed-loop sweat treatment system is constructed through the synergistic effect of a skin-friendly, moisture-wicking inner layer, a one-way water-wicking middle layer, and a rapidly evaporating outer layer, enabling moisture absorption, water conduction, and evaporation. The skin-friendly, moisture-wicking inner layer quickly absorbs sweat from the skin's surface; the one-way water-wicking middle layer utilizes capillary effect and surface tension difference to achieve directional sweat transport; and the rapidly evaporating outer layer accelerates sweat evaporation by increasing the specific surface area and diffusion area, ensuring the inner side of the fabric remains dry at all times. The composite process using a nylon 66 fiber-reinforced one-way water-wicking middle layer and low-melting-point polyamide particles gives the fabric excellent structural stability and washability.

[0016] Explanation of reference numerals in the attached diagram: 1. Skin-friendly and moisture-wicking inner layer; 2. One-way water-wicking middle layer; 3. Rapidly evaporating outer layer. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings: like Figure 1 As shown, the skin-friendly and moisture-wicking inner layer 1, as the layer in direct contact with human skin, has the core function of quickly absorbing sweat seeping from the skin surface and providing the wearer with a soft, skin-friendly feel. This inner layer is woven from modified cotton-polyester blended yarn in a plain weave, and the fabric surface is brushed.

[0018] The raw material is a blend of cotton fiber and modified polyester fiber, with cotton fiber accounting for 60%-70% and modified polyester fiber accounting for 30%-40%. The modified polyester fiber is hydrophilic by grafting hydroxyl hydrophilic groups onto its surface, increasing its hydrophilicity by more than 40% compared to unmodified polyester fiber, which can significantly enhance the moisture absorption rate of the inner layer. The blended yarn is woven using a ring spinning process, with a yarn fineness of 32S-40S and a twist of 800-1000 twists / meter. These parameters are designed to ensure both yarn strength and good softness and uniform moisture absorption. The fabric is woven in a plain weave with a warp density of 380-420 threads / 10cm and a weft density of 320-360 threads / 10cm. The fabric weight is controlled at 80-100g / ㎡. After weaving, the fabric surface is brushed with a brushing length of 0.3-0.5mm. The brushing process further enhances the softness and comfort of the fabric when in contact with the skin, reducing friction during exercise.

[0019] The unidirectional hydrophobic interlayer 2 is the core layer that enables the fabric to achieve its unidirectional hydrophobic function. Its function is to quickly and directionally transfer the sweat absorbed by the skin-friendly and moisture-wicking inner layer 1 to the fast-evaporating outer layer 3, while preventing sweat from penetrating back from the outer layer to the inner layer. This interlayer is made of irregularly shaped polyester fibers and polyamide fibers interwoven to form a perforated fabric, and the fabric is treated with a directional hydrophilic-hydrophobic treatment.

[0020] The warp yarns are made of trilobal cross-section polyester fiber with a fineness of 75D / 36F. The trilobal cross-section forms natural capillary channels within the fiber, accelerating sweat transport through capillary action. The weft yarns are made of nylon 66 fiber with a fineness of 50D / 24F. Nylon 66 fiber possesses excellent strength and abrasion resistance, effectively enhancing the structural stability and interlayer bonding of the intermediate layer. The weaving employs a perforated structure with a warp density of 450-500 ends / 10cm and a weft density of 380-420 ends / 10cm, resulting in a fabric weight of 100-120g / ㎡. The porous structure of the perforated structure not only further enhances capillary water conduction efficiency but also ensures the fabric's breathability. The functional finishing process employs a double-sided differentiated treatment: the side closest to the skin-friendly and moisture-wicking inner layer 1 is coated with a polyethylene glycol-based hydrophilic finishing agent, resulting in a contact angle of ≤30° on this side, enhancing the adsorption and conduction of sweat; the side closest to the fast-evaporating outer layer 3 is coated with an organosilane-based hydrophobic finishing agent, resulting in a contact angle of ≥120° on this side, creating a surface tension difference that drives sweat to be transported unidirectionally from the hydrophilic side to the hydrophobic side, while simultaneously preventing sweat from penetrating back.

[0021] The core function of the rapid evaporation outer layer 3 is to quickly diffuse and evaporate the sweat transferred from the one-way water-wicking middle layer 2 into the external environment, keeping the outer side of the fabric dry. This outer layer is made of ultra-fine polyester fibers woven in a twill weave and is treated with antistatic and UV-resistant finishes.

[0022] The raw material is made of ultra-fine polyester fiber with a fineness of 50D / 72F. The fiber cross-section is designed in a dumbbell shape, which increases the specific surface area of ​​the fiber and improves the evaporation rate of sweat. The weave uses a twill weave with a warp density of 350-380 threads / 10cm and a weft density of 300-330 threads / 10cm, resulting in a fabric weight of 70-90g / ㎡. The surface texture created by the twill weave further increases the diffusion area of ​​sweat on the fabric surface, accelerating sweat evaporation. In the finishing process, antistatic and UV-resistant finishing are performed sequentially: antistatic finishing uses an antistatic agent coating at a rate of 2g / ㎡ to achieve the antistatic performance of the fabric meeting the Class A requirements of GB / T12703.1-2008; UV-resistant finishing uses a UV-resistant agent coating at a rate of 3g / ㎡ to achieve the UV resistance of UPF 30+, meeting the needs of casual sportswear and outdoor wear.

[0023] To ensure a strong bond between the three layers while avoiding any impact on the functionality of each layer, this invention employs a hot melt adhesive dot bonding process. Specific process parameters are as follows: low-melting-point polyamide granules are used as the hot melt adhesive, with a dot diameter of 0.3-0.5 mm and a dot spacing of 5-8 mm; the bonding temperature is controlled at 120-140℃, and the bonding pressure is 0.3-0.5 MPa. This process achieves the fixation of the three-layer structure through dot bonding, avoiding the reduced fabric breathability problem caused by traditional full-area bonding. Simultaneously, the low-melting-point polyamide granules possess excellent adhesive strength and washability, ensuring that the fabric maintains stable interlayer bonding even after multiple washes.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope of the invention. All such changes and modifications fall within the scope of the invention as claimed, which is defined by the appended claims and their equivalents.
