Description

Technical Field

[0001] This utility model relates to a skin-friendly, quick-drying and moisture-wicking denim fabric, belonging to the textile field. Background Technology

[0002] Traditional denim fabric is woven from indigo-dyed warp yarns and off-white weft yarns. After more than a century of development, it holds an irreplaceable position in the clothing market. With economic development and improved living standards, people's pursuit of denim clothing has expanded beyond design to include comfort and functionality. For example, in hot summers, people need comfortable clothing that quickly wicks away moisture. Existing technologies use synthetic fibers with irregular cross-sections, such as polyester and nylon, to achieve moisture wicking. However, polyester and nylon filaments have poor moisture absorption; for example, polyester's moisture absorption is only 0.4%. When manufacturing fabrics using these yarns, hydrophilic finishing agents are typically used to improve moisture absorption. However, hydrophilic finishing occurs in the post-fabric finishing stage. Denim garments undergo multiple washing processes (enzyme bleaching, oxygen bleaching, chlorine bleaching, manganese bleaching, etc.) after garment making to age the fabric. Hydrophilic substances are easily removed during these washing processes, resulting in decreased moisture absorption. Furthermore, some hydrophilic finishing agents can irritate the skin and cause allergies. Hemp fibers have a large central cavity with numerous longitudinally connected slits and pores, giving the fibers numerous capillary channels that can quickly transfer and diffuse moisture and water vapor within the fabric. They also possess natural antibacterial properties, making them promising for use in moisture-wicking clothing. However, fabrics woven from hemp fibers are prone to creases and wrinkles, have poor dimensional stability, and are more susceptible to shrinkage. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a skin-friendly and quick-drying denim fabric that can not only give full play to the advantages of hemp fiber in absorbing and wicking away moisture, but also is not prone to creases and has good dimensional stability.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A skin-friendly, quick-drying denim fabric comprises interwoven warp and weft yarns, wherein the weft yarns include a first filament arranged side by side, hemp yarn, and porous hollow polyester, wherein the hemp yarn is finer than the first filament and the porous hollow polyester, and the sum of the number of the first filament and the porous hollow polyester is greater than the number of the hemp yarn; the first filament has a coaxial structure, and the outer layer of the first filament is an adhesive layer.

[0006] The skin-friendly, quick-drying denim fabric provided in this application utilizes hemp yarn and porous hollow polyester to achieve the effect of moisture wicking and perspiration removal. The hemp yarn and the viscose layer of the first filament work together to achieve the effects of skin-friendliness, moisture absorption, and breathability. Both the first filament and the porous hollow polyester are long filaments, and the first filament and the porous hollow polyester are thicker and more numerous than the hemp yarn, making the fabric less prone to wrinkling.

[0007] Furthermore, the first filament also includes a shaped cross-section polyester layer and a porous polyurethane layer wrapped around the surface of the shaped cross-section polyester layer, and the adhesive layer is wrapped around the surface of the porous polyurethane layer.

[0008] The surface of the irregular cross-section polyester layer is connected to the pores of the porous polyurethane layer, which has a moisture-wicking effect. It can axially transport the moisture absorbed by the adhesive layer, accelerate the transfer of moisture to a farther position on the same yarn, and facilitate faster moisture evaporation. In addition, the irregular cross-section polyester layer inside the first filament plays a weaving role for the first filament, which can improve the wrinkle resistance of the fabric.

[0009] In a preferred embodiment, the warp yarns comprise parallel cotton yarns and viscose yarns.

[0010] Furthermore, the cotton yarn and the viscose yarn are arranged in a 1:1 ratio.

[0011] In a preferred embodiment, the first filament and the porous hollow polyester are of equal thickness.

[0012] Furthermore, the yarn count of the hemp yarn is 5 to 8 times that of the yarn count of the first filament.

[0013] In a preferred embodiment, the sum of the number of the first filament and the number of the porous hollow polyester is twice the number of hemp yarn threads.

[0014] This ratio optimizes the yarn arrangement density, which helps to make the fabric more compact and less prone to cracking, while ensuring the fabric's softness and wrinkle resistance.

[0015] Furthermore, the first filament and the porous hollow polyester are arranged in a 1:1 ratio.

[0016] In a preferred embodiment, each of the hemp yarns is located between a first filament and a porous hollow polyester.

[0017] In a preferred embodiment, the warp yarns and the weft yarns are interwoven in a three-up-one-down twill pattern.

[0018] The three-up-one-down twill structure can create the texture of traditional denim fabric, and the fabric base of this structure has many weft points, which can give full play to the moisture-wicking and moisture-absorbing properties obtained by the combination of three weft yarns.

[0019] The beneficial effects of this invention are as follows: The skin-friendly and quick-drying denim fabric of this invention utilizes hemp yarn and porous hollow polyester to achieve the effect of moisture wicking and perspiration wicking, and utilizes the hemp yarn and the viscose layer of the first filament to achieve the effects of skin-friendliness, moisture absorption, and breathability. Both the first filament and the porous hollow polyester are filaments, and the first filament and the porous hollow polyester are thicker and more numerous than the hemp yarn, making the fabric less prone to wrinkling. It can give full play to the advantages of hemp fiber in absorbing and wicking moisture, and is not prone to creases, thus having good dimensional stability.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or reference letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0027] Unless otherwise specified, all technical and scientific terms used herein have the standard meaning in the field to which the claimed subject matter pertains. Where multiple definitions exist for a term, the definition herein shall prevail.

[0028] Reference Figures 1 to 3 This application provides a skin-friendly, quick-drying denim fabric, comprising interwoven warp yarns 1 and weft yarns. The weft yarns include a first filament 21, hemp yarn 22, and porous hollow polyester 23 arranged side by side. The hemp yarn 22 is finer than the first filament 21 and the porous hollow polyester 23. The sum of the number of the first filament 21 and the porous hollow polyester 23 is greater than that of the hemp yarn 22. The first filament 21 has a coaxial structure, and the outer layer of the first filament 21 is an adhesive layer 211.

[0029] The filament fibers have good wrinkle resistance. The first filament 21 and the porous hollow polyester 23 are both filaments. The first filament 21 and the porous hollow polyester 23 are thicker and more numerous than the hemp yarn 22, making the fabric less prone to wrinkling.

[0030] Both the viscose layer 211 and the hemp yarn 22 on the surface of the first filament 21 have good moisture absorption capacity. The hemp yarn 22 and the porous hollow polyester 23 both have interconnected pores, allowing for moisture wicking through capillary action. When the wearer sweats, the viscose layer 211 absorbs moisture first. As the wearer continues to sweat, the finer hemp yarn 22 absorbs moisture, and then the hemp yarn 22 and the porous hollow polyester 23 transfer the moisture to a more distant location. This effectively spreads the sweat quickly across the fabric, increasing the evaporation area and accelerating moisture evaporation, thus achieving the effect of moisture absorption and perspiration wicking.

[0031] Viscose yarn is a type of yarn that is absorbent and has good moisture absorption, but it is prone to causing fabric shrinkage. In the embodiments of this application, refer to Figure 2 The first filament 21 also includes a shaped cross-section polyester layer 213 and a porous polyurethane layer 212 wrapped around the surface of the shaped cross-section polyester layer 213, with an adhesive layer 211 wrapped around the surface of the porous polyurethane layer 212. Using the shaped cross-section polyester layer 213 as the "backbone" of the first filament 21 provides support and inhibits shrinkage. Simultaneously, the surface of the shaped cross-section polyester layer 213 is connected to the pores of the porous polyurethane layer 212, providing moisture-wicking properties. This allows for axial transport of moisture absorbed by the adhesive layer 211, accelerating moisture transfer to more distant locations on the first filament 21 and promoting faster evaporation.

[0032] The structure of the first filament can be obtained through coaxial spinning, specifically three-channel coaxial spinning, with solutions of three layers of raw materials prepared separately, one solution corresponding to one channel. The spinneret corresponding to the innermost channel is set with an irregular shape, such as a cross shape or a plum blossom shape, and after spinning, an irregular cross-section polyester layer 213 can be obtained; a foaming agent is added to the solution corresponding to the middle channel, and after spinning, a porous polyurethane layer 212 can be obtained.

[0033] Reference Figure 1 and Figure 3 The warp yarn 1 and the weft yarn are interwoven in a three-up-one-down twill pattern. This structure can create the texture of traditional denim fabric. In addition, the weft weave points are more than the warp weave points in the fabric base of this structure, which can give full play to the moisture-wicking and moisture-absorbing properties obtained by the combination of the first filament 21, hemp yarn 22, and porous hollow polyester 23.

[0034] Accordingly, the warp yarns can be made of yarns with good moisture absorption and easy dyeing to achieve the appearance of denim fabric and further improve the fabric's moisture absorption and wicking capabilities. For example, the warp yarn 1 includes cotton yarn 11 and viscose yarn 12 arranged side by side. When sewing clothing, the fabric back faces inward, that is, it is in direct contact with the skin; when the wearer sweats, the fabric back absorbs sweat first, and the moisture is transferred to the warp yarn 1 by the moisture-wicking ability of the weft yarns. Based on the three-up-one-down twill weave structure, there are more warp weave points than weft weave points on the front side of the fabric. The highly absorbent cotton yarn 11 and viscose yarn 12 absorb a large amount of moisture and evaporate it outward over a large area on the front side of the fabric. Preferably, the cotton yarn 11 and viscose yarn 12 are arranged in a 1:1 ratio.

[0035] In a preferred embodiment, the first filament 21 and the porous hollow polyester 23 are of equal thickness. Meanwhile, the count of the hemp yarn 22 is 5 to 8 times that of the first filament 21. Because the hemp yarn 22 is finer, it will be closer to the interior of the fabric after weaving (see reference). Figure 3 The hemp yarn 22 can play a role in absorbing and wicking moisture inside the fabric. Moreover, the difference in thickness between the hemp yarn 22 and the first filament 21 and the porous hollow polyester 23 is relatively large, which helps to eliminate the adverse effect of the hemp yarn 22 being prone to wrinkles.

[0036] Reference Figure 1 The total number of first filaments 21 and porous hollow polyester 23 is twice the number of hemp yarns 22. Simultaneously, the first filaments 21 and porous hollow polyester 23 are arranged in a 1:1 ratio, equivalent to a 1:1:1 ratio of first filaments 21, hemp yarns 22, and porous hollow polyester 23. The hemp yarns 22 and porous hollow polyester 23 provide moisture wicking, while the viscose layer 211 of the hemp yarns 22 and the first filaments 21 provides moisture absorption. This weaving ratio balances the fabric's moisture absorption and wicking properties.

[0037] Preferably, each hemp yarn 22 is located between a first filament 21 and a porous hollow polyester 23. This precise arrangement of yarns creates a stable moisture-wicking structure, allowing the fabric to fully exert its moisture absorption and wicking functions. The three weft yarns work together to achieve efficient conduction and diffusion of sweat.
