Description

Technical Field

[0001] This utility model relates to the field of fabric technology, and more specifically, to unidirectional moisture-wicking outdoor fabrics. Background Technology

[0002] With the improvement of people's living standards and the rise of outdoor sports, the demand for functional textiles is increasing. One-way moisture-wicking fabric, as an important functional fabric, can quickly wick away the sweat produced by the human body to the outer layer of the fabric, keeping the skin dry and comfortable. It has broad application prospects in sportswear, outdoor clothing, underwear and other fields.

[0003] To improve the moisture-wicking effect of existing fabrics, the fabric structure is usually modified to achieve unidirectional moisture wicking by utilizing capillary effect and pressure difference. However, this method is complex, costly, and difficult to precisely control the moisture-wicking effect. Another method is to perform hydrophilic or hydrophobic finishing on the fabric to create a hydrophilic-hydrophobic difference between the inner and outer surfaces, thereby achieving unidirectional moisture wicking. However, traditional finishing techniques have problems such as poor durability and stiffening of the hand feel, and it is difficult to balance moisture wicking performance with other performance indicators.

[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 one-way moisture-wicking outdoor fabric.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: the unidirectional moisture-wicking outdoor fabric includes a fabric layer, the fabric layer is configured as a double weft weave, the fabric layer is woven from a set of warp yarns and two sets of weft yarns, the two sets of weft yarns are a set of outer weft yarns and a set of inner weft yarns, the outer weft yarns include a plurality of alternately arranged moisture-wicking yarns and breathable yarns, the inner weft yarns include a plurality of alternately arranged moisture-wicking yarns and support yarns, the moisture-wicking yarns and moisture-wicking yarns are arranged correspondingly, and the breathable yarns and support yarns are arranged correspondingly.

[0007] The present invention is further configured such that: the supporting yarn is a node yarn, and a plurality of supporting nodes are fixedly connected to the outer peripheral wall of the supporting yarn, and the supporting nodes abut against the breathable yarn.

[0008] The present invention is further configured such that: the diameter of the support node position is larger than the yarn diameter of other areas of the support yarn, and the support node supports the formation of a flow cavity between the support yarn and the breathable yarn.

[0009] The present invention is further configured such that the arrangement density of the outer weft yarn is greater than that of the inner weft yarn.

[0010] The present invention is further configured such that the width of the moisture-wicking yarn is greater than the width of the breathable yarn.

[0011] The present invention is further configured such that: the moisture-wicking yarn is composed of several 75D unidirectional moisture-wicking polyester DTY, the breathable yarn is configured as 40D spandex core-spun yarn, and the outer covering yarn of the 40D spandex core-spun yarn is cotton fiber.

[0012] The present invention is further configured such that: the moisture-wicking yarn is 40D spandex core-spun yarn II, the outer covering yarn of the 40D spandex core-spun yarn II is bamboo fiber, and the supporting yarn includes 40D nylon DTY and 75D unidirectional moisture-wicking polyester DTY.

[0013] In summary, this utility model has the following beneficial effects: The moisture-wicking yarns in the outer weft yarns are in direct contact with the skin, quickly absorbing and transferring sweat using their unidirectional moisture-wicking properties, while the breathable yarns promote air circulation and accelerate sweat evaporation. The moisture-dissipating yarns in the inner weft yarns are positioned in conjunction with the moisture-wicking yarns, further diffusing sweat into the air. Support yarns form circulation chambers through support nodes, increasing the airflow area and significantly improving the fabric's drying speed. The support nodes, formed by a fancy twisting machine, not only enhance the fabric's support but also utilize the unidirectional moisture-wicking properties of 75D unidirectional moisture-wicking polyester DTY to further promote sweat transfer. The ratio of outer to inner weft yarns is 2:1, ensuring a larger contact area between the outer fabric and the skin, while some outer fabric is exposed through the inner fabric, increasing the contact area with the outside air and enhancing overall functionality.

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

[0017] This one-way moisture-wicking outdoor fabric, such as Figure 1 and Figure 2As shown, the fabric includes a double-weft weave, consisting of one set of warp yarns and two sets of weft yarns. The outer fabric of the double-weft weave is a 3 / 3 twill weave, as is the inner fabric. The two sets of weft yarns consist of one outer weft yarn and one inner weft yarn. The fabric is woven from the warp yarns and the two sets of weft yarns, with an outer weft yarn to inner weft yarn ratio of 2:1. After weaving, the outer fabric is positioned closer to the body surface, resulting in a larger contact area between the yarns in the outer fabric and the body surface. The inner fabric has a smaller proportion of weft yarns, allowing some of the outer fabric to be exposed through the inner fabric, which also increases the contact area between the outer fabric and the outside air, accelerating the evaporation rate of sweat in the outer fabric.

[0018] The outer weft yarn includes several alternating moisture-wicking yarns 1 and breathable yarns 2, and the inner weft yarn includes several alternating moisture-wicking yarns 3 and support yarns 4. The moisture-wicking yarns 1 and moisture-wicking yarns 3 are arranged correspondingly, and the breathable yarns 2 and support yarns 4 are arranged correspondingly. After the moisture-wicking yarns 1 come into contact with the body surface, they attract sweat from the body surface, accelerating the transfer efficiency of sweat on the body surface. The breathable yarns 2 have good breathability, which facilitates the circulation and exchange of air on both sides and improves the comfort of wearing the fabric. The moisture-wicking yarns 3 are arranged correspondingly to the moisture-wicking yarns 1, and the moisture-wicking yarns 1 attract sweat from the body surface.

[0019] The supporting yarn 4 is set as a node yarn, and several supporting nodes are fixedly connected to the outer peripheral wall of the supporting yarn 4. The supporting nodes abut against the breathable yarn 2. The diameter of the supporting node position is larger than the yarn diameter of other areas of the supporting yarn 4. The supporting nodes support the supporting yarn 4 and the breathable yarn 2 to form a flow cavity. The width of the moisture-wicking yarn 1 is larger than the width of the breathable yarn 2, so that the contact area between the moisture-wicking yarn 1 and the body surface is larger, attracting sweat on the body surface to the moisture-wicking yarn 1. The supporting yarn 4 is woven into the fabric in one piece through a double weft structure. Since the diameter at the supporting node is larger than the diameter of other areas of the supporting yarn 4, after the supporting node comes into contact with the breathable yarn 2, it pushes up the other areas of the supporting yarn 4 and the outer side of the breathable yarn 2 to form a flow cavity. More air flows on the outer side of the breathable yarn 2 and the supporting yarn 4, increasing the contact area between the inside of the fabric and the air, thereby improving the drying speed of the fabric.

[0020] Moisture-wicking yarn 1 consists of several 75D unidirectional moisture-wicking polyester DTY yarns, utilizing the unidirectional moisture-wicking properties of the modified polyester yarn to transfer sweat from the body surface. Breathable yarn 2 is a 40D spandex core-spun yarn, with cotton fiber as the outer covering. Moisture-wicking yarn 3 is a 40D spandex core-spun yarn, with bamboo fiber as the outer covering. Support yarn 4 includes 40D nylon DTY and 75D unidirectional moisture-wicking polyester DTY. Nylon DTY and 75D unidirectional moisture-wicking polyester DTY are fed into a fancy twisting machine. During the feeding process, the nylon roller is paused while the polyester roller continues to feed, thus winding the nylon yarn to form several support nodes. Therefore, the main material of the support nodes is 75D unidirectional moisture-wicking polyester DTY. The unidirectional moisture-wicking property of this yarn is also used to transfer sweat in the breathable yarn 2. Both breathable yarn 2 and moisture-wicking yarn 3 are made of spandex core-spun yarn. Spandex yarn has good elasticity and elastic recovery, which improves the overall elasticity of the fabric. The outer covering yarn of breathable yarn 2 is made of cotton fiber, while the outer covering yarn of moisture-wicking yarn 3 is made of bamboo fiber. Both cotton fiber and bamboo fiber have good breathability. In addition to being breathable, bamboo fiber also has good moisture absorption and dissipation effects, allowing sweat on moisture-wicking yarn 1 to diffuse into the air more quickly.

[0021] The prepared yarn is woven according to the double weft structure cycle. After the warp yarns are threaded through the reed and fixed, the weft yarns are woven onto the warp yarns. The warp yarns are also made of 75D unidirectional moisture-wicking polyester DTY. The outer weft yarn and the inner weft yarn are woven according to the established pattern to obtain this fabric.

[0022] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
