Structure and manufacturing method of unidirectional moisture wicking fabric

The present invention relates to a fabric structure, and more particularly to a method and structure for producing a unidirectional moisture wicking woven fabric.

In the field of woven fabrics, "moisture wicking" means that the non-hydrophilic fabric has both water absorption and fast drying properties. In general, it is difficult to combine both properties with natural fibers or synthetic fibers. For example, the commonly used rayon-polyester (Polyester) has a low moisture content and poor hydrophilicity, resulting in poor moisture absorption of the fabric. Today's moisture wicking fabrics can be made using several techniques, including: microfibers, profiled cross-section fibers, hollow microporous fibers, and fiber surface modification. The most commonly used method in textiles is to use a highly hydrophilic moisture absorbent to process the above-mentioned rayon fabric to make the rayon fabric have a moisture absorbing effect. Generally, moisture wicking fabrics are widely used in the field of sports or outdoor recreation. The sweat must be able to spread on the fabric very quickly. The larger the diffusion area, the larger the evaporation area and the greater the quick-drying effect, so these fabrics are also more Generally, the fabric is more quickly and dry.

In the prior art, such fabrics were woven with warp and weft using rayon fibers. After completion, the hydrophilic processing is used to make the whole piece of cloth which is not hydrophilic to have hygroscopic property, and the sweat spreads on the cloth to make it have a quick-drying effect, but the cloth spreads simultaneously with the inner layer due to the diffusion of sweat in the cloth ( The inner and outer diffusion areas are the same), so that the inner side stays sweat to make the cloth stick to the skin, which makes the wearer feel uncomfortable.

The main object of the present invention is to distinguish the two-sided structure and the property characteristics of the single layer fabric, and the warp yarn weft yarns can be connected to each other to form a unidirectional moisture wicking cloth structure, so that the sweat is quickly contacted by the skin. The inside is quickly transported to the surface and quickly spreads over a large area of the surface.

For the purpose of the foregoing disclosure, the structure of the unidirectional moisture wicking fabric of the present invention comprises a first rayon fiber and a second rayon fiber, and the material thereof comprises rayon fibers such as polyester and polyamide. The first rayon surface is impregnated with a moisture absorbent; and the second rayon surface is impregnated or coated with a water repellent. The first rayon fiber and the second rayon fiber are interlaced to form a first surface and a second surface, and the ratio of the second rayon fiber to the first surface contacting the skin is between 50% and 90%. And gather sweat at the first rayon of the first surface to deliver sweat to the second surface.

The method for manufacturing a unidirectional moisture wicking fabric according to the present invention is characterized in that a first rayon which is generally unprocessed and a second rayon which is impregnated or coated with a water repellency agent are interlaced to form a fabric, which is dyed and dyed. Hydrophilic processing, the moisture absorbent is attached to the first rayon, so that the first rayon is hygroscopic, and the other dyeing and hydrophilic processing does not affect the hydrophobic effect of the second rayon. The cloth comprises a first surface and a second surface, and the ratio of the second rayon fibers in the first surface contacting the skin is between 50% and 90%, and the sweat is concentrated on the first surface. The first rayon of the surface is provided for perspiration to be delivered to the second surface.

Obviously, the implementation of the present invention is not limited to the specific details familiar to those skilled in the relevant art. On the other hand, well-known structures or steps are not described in detail to avoid unnecessarily limiting the invention. The preferred embodiments of the present invention are described in detail below, but the present invention may be widely practiced in other embodiments, and the scope of the present invention is not limited by the scope of the following patents. .

Referring to FIG. 1, the unidirectional moisture wicking woven fabric 10 is interwoven by warp and weft, and the moisture wicking fabric 10 includes a first surface 11 contacting the skin and a corresponding second. Surface 12. In this embodiment, the warp and weft of the moisture wicking fabric 10 may be composed of the first rayon and the second rayon, respectively. The surface of the first rayon is impregnated with a moisture absorbent, so that the first rayon has hygroscopic properties, and the surface of the second rayon is coated with a water repellent, so that the second rayon has hydrophobic properties. Specifically, after the second rayon is pre-coated with the water-repellent agent in the process, the first rayon and the second rayon coated with the water-repellent agent are co-impregnated in the moisture absorbent to perform moisture absorption treatment, but The surface of the second rayon water repellent has been pretreated, so that the moisture absorbent cannot adhere or adsorb on the surface of the second rayon, so that the second rayon fiber still maintains hydrophobic properties. In addition, the strength of the first rayon and the second rayon is from 2g/D (Danny) to 40g/D (Danny), and the specification is from 15D (Danny) to 2000D (Danny).

In the moisture wicking fabric 10 shown in FIG. 1, the first rayon and the second rayon may be selected from the group consisting of polyethylene terephthalate (Polyester), polyamine fiber (Polyamide), and cationic dyeable copolyester. (CATIONIC DYEABLE Materials such as POLYESTER) or materials that provide the same fiber function. The moisture absorbent is a hydrophilic resin, wherein the hydrophilic resin may be selected from the group consisting of polyacrylates, polyacrylonitrile hydrolyzed compounds, vinyl acetate copolymers, and polyvinyl alcohol. Specifically, ethylene terephthalate and a cationic dyeable copolyester are treated with a polyester resin, and polyamine fibers can be treated with a nonionic water-resistant water-absorbent resin. Further, the water repellent is selected from the group consisting of a Silicone-based fluorocarbon water repellent and a fluorine-free water repellent.

Figure 2 is a cross-sectional line 1-1 of Figure 1. Referring to Figures 1 and 2, the second rayon 21 of the rayon is located on the first surface 11 adjacent to the skin 30. In this embodiment, the weft yarn 22 and the warp yarn 23 adjacent to the second surface 12 are composed of the first rayon. Therefore, the first rayon fibers having high water absorbency are mainly distributed on the second surface 12. In addition, FIG. 3 shows the connection relationship between the warp yarns 23 and the weft yarns 21 of the second rayon fibers in another cross section (not shown).

The moisture wicking fabric 10 of the present invention is mainly formed by a double face weave, so that the first surface 11 and the second surface 12 are also woven by a double woven fabric as shown in FIG. . Referring to FIG. 1 and FIG. 2, the ratio of the second rayon 21 of the second rayon to the first surface 11 of the skin 30 is between 50% and 90%, because the second rayon surface is coated with a water repellent. Therefore, the surface of the second rayon water repellent (50% to 90% of the first surface 11) can concentrate the sweat of the skin 30 on the weft yarn 22 of the first rayon of the first surface 11. Since the surface of the moisture absorbent of the first rayon is hydrophilic, the second surface 12 is provided for the sweat to be transported to a larger ratio of the area occupied by the first rayon. In other words, the ratio of the warp yarn 23 of the first rayon to the first surface 11 is between 10% and 50% and contacts the skin 30, the moisture absorbent of the first rayon. The face can be transported by the first surface 11 to the second surface 12.

4 to 12 show an embodiment of various patterns formed by the warp yarns 23 and the weft yarns 21 of Fig. 2, and Figs. 4 to 12 show the second surface 12 of the unidirectional moisture wicking cloth 10. As shown in Figures 4 to 12, the black portion appears as the warp yarn 23 of the first rayon, and the white portion appears as where the weft yarn 21 of the second rayon is located. In the second surface 12, the ratio of the warp yarns 23 of the first rayon is between 50% and 90% (for example, in Fig. 12, the case where the warp yarns 23 occupy 20 grids in a complete structure of 25 grids) . In other words, the ratio of the weft yarns 21 of the second rayon is between 10% and 50%. Since the ratio of the warp yarns 23 of the first rayon to the second surface 12 is relatively high, the ratio of the warp yarns 23 of the first rayon fibers to the first surface 11 is relatively low, thereby contacting the second surface 12 The sweat can quickly diffuse through the surface of the moisture absorbent of the first rayon, and since the ratio of the first rayon fibers to the second surface 12 is relatively high, most of the sweat is concentrated on the second surface 12 and diffused due to The second surface 12 is an outer layer of cloth and is in contact with the outside air, so that the sweat can be quickly dried and evaporated to achieve moisture wicking when worn. In addition, as shown in the embodiments of FIG. 4, FIG. 5, FIG. 6, FIG. 7, FIG. 8, FIG. 9, FIG. 10, FIG. 11, and FIG. 12, the structure is twill, chaotic and segment, the first man-made fiber. The surface with a higher ratio is the second surface 12 (outer layer of cloth). On the other hand, the face having a lower ratio of the first rayon is the first surface 11 (the inner layer of the cloth), and the sweat is quickly applied by the surface of the moisture absorbing agent 23 of the warp yarn 23.

In addition, the present invention also provides a method for manufacturing a moisture wicking fabric having a unidirectional property, wherein the first rayon coated with a moisture absorbent is interlaced with the second rayon coated with a water repellent agent to form a first a surface and a second surface, the ratio of the second rayon to the first surface contacting the skin Between 50% and 90%, and sweat is collected at the first rayon of the first surface for sweat to be delivered to the second surface.
