Description

Technical Field

[0001] This utility model relates to the field of composite fabric technology, specifically to a moisture-wicking, skin-friendly, and comfortable cotton, hemp, and polyester knitted fabric. Background Technology

[0002] Hemp fiber molecules contain a large number of polar hydrophilic groups, which easily combine with water molecules upon contact and adsorb them. Furthermore, due to the unique structure of hemp fibers, the fiber center has a large cavity with numerous longitudinally connected fissures and pores, giving the fiber numerous capillary channels. This allows for the rapid transfer and diffusion of moisture and water vapor within the fabric. When the body sweats, these structures in hemp fabric can promptly wick sweat or moisture to the fabric surface, allowing it to dissipate into the air and keep the skin dry. Its sweat absorption rate is twice that of commonly used cotton fabrics. Compared to other natural plant fibers (such as cotton), hemp has another advantage: its cultivation requirements are relatively simple, it does not encroach on arable land used for food crops, and it is particularly suitable for hillsides, wastelands, and saline-alkali land. Therefore, it can be said that hemp is an eco-friendly and economically viable fiber resource.

[0003] However, traditional hemp fabrics also have certain drawbacks. The surface of these fabrics typically contains a large number of short, stiff hemp fibers, resulting in a stiff overall texture and a lack of softness. Furthermore, these short fibers floating on the surface can irritate the skin and cause itching. Additionally, because hemp fibers have virtually no elasticity and a highly irregular structure, the fabric is prone to wrinkling after stretching and folding, lacking crispness. Moreover, hemp fabrics are currently mostly used for lightweight clothing, and in rainy seasons with high humidity and frequent contact with sweat, the fabric is easily contaminated and can carry bacteria. These drawbacks limit the large-scale use of hemp fabrics in textiles. Therefore, developing moisture-wicking, antibacterial, and skin-friendly fabrics to increase the wider use of this natural organic material in textile products is of practical significance. Utility Model Content

[0004] This invention provides a moisture-wicking, skin-friendly, and comfortable cotton, hemp, and polyester knitted fabric to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A moisture-wicking, skin-friendly, and comfortable cotton-linen-polyester knitted fabric includes a main body of fabric, which includes a pure linen antibacterial layer and two sides of a multi-linen outer layer and a polyester stiffening layer, a composite outer layer on the other side of the multi-linen outer layer and a composite inner layer on the other side of the polyester stiffening layer.

[0007] The composite outer and inner layers are made of cotton-hemp yarn blended and then blended with polyester; the multi-hemp outer layer is made of hemp and polyester blended; the pure hemp antibacterial layer material is hemp fiber loaded with antibacterial material, and the polyester stiffening layer material is polyester.

[0008] In this preferred embodiment, the composite outer and inner layers are made by blending cotton-hemp yarns and then polyester. First, long-staple cotton and hemp yarns are blended to obtain a yarn that is strong, smooth, and softer than pure hemp fiber. Then, short-staple cotton-hemp yarns are alternately interwoven with polyester filaments to obtain a blended yarn, which is used as the material for weaving the composite outer and inner layers. The final fabric combines the advantages of hemp, cotton, and polyester, resulting in a fiber fabric that is moderately soft and firm, smooth and wrinkle-free, with good luster, and is skin-friendly and breathable.

[0009] Between the composite outer layer and the composite inner layer, three tightly fitted inner layers are designed. The multi-layered outer layer is a blend of hemp and polyester; the pure hemp antibacterial layer is made of hemp fibers loaded with antibacterial materials; and the polyester stiffening layer is made of polyester. From the multi-layered outer layer through the pure hemp antibacterial layer to the polyester stiffening layer, the hemp content in the fabric fibers first increases and then decreases, while the polyester content first decreases and then increases. In the design process, the composite outer layer, made from the materials of this invention, is the outermost layer, and the composite inner layer is the inner side of the fabric closest to the user's skin. Therefore, placing more hemp-containing raw materials on the outer side of the body increases the dilution and perspiration-wicking effect, while placing more soft polyester materials on the inner side of the body ensures smoothness and comfort.

[0010] Furthermore, in the composite outer layer and composite inner layer, the mass ratio of each material in the yarn is 30-60% long-staple cotton, 5-30% hemp, and 40-70% polyester.

[0011] In this preferred embodiment, the composite outer layer and the composite inner layer are made of polyester filament and cotton-hemp staple fiber blended yarn. The raw materials are Xinjiang long-staple cotton and hemp blended yarn and iterated polyester filament, which have the characteristics of moisture absorption, perspiration wicking, odor prevention, lightness, softness and skin-friendliness.

[0012] Polyester filament and cotton / linen staple fiber blended yarns can leverage the properties of both filament and staple fiber yarns to create a composite yarn that exhibits the characteristics of both components. The polyester filament provides high modulus and tensile strength, improving the fabric's shape retention and crispness; while the cotton / linen staple fiber yarn offers the fabric's natural fiber feel, softness, bulkiness, and better moisture absorption.

[0013] Furthermore, in the aforementioned multi-layered outer layer, the mass ratio of each material in the yarn is 40-60% hemp and 40-60% polyester.

[0014] Furthermore, in the pure hemp antibacterial layer, the antibacterial material loaded on the hemp fibers is nano-silver particles.

[0015] This preferred solution selects nano-silver particles as the antibacterial material on hemp fibers. Utilizing the natural antibacterial properties of nano-silver, the number of viable bacteria is minimized, ensuring the fabric's antibacterial properties. Even in rainy seasons or during periods of heavy sweating or exercise, the fabric can reduce moisture buildup and inhibit bacteria, maintaining internal cleanliness.

[0016] Furthermore, the polyester is a semi-dull 100D / 144F white iterative polyester filament.

[0017] This preferred solution utilizes iterative polyester, a special polyester material with numerous advantages. It boasts a suitable moisture regain of 1.4%–2.0%, requiring no additive treatment and exhibiting rapid diffusion and evaporation upon contact with moisture; it has low static electricity, reducing itching and preventing static cling; and it exhibits superior anti-pilling properties compared to ordinary polyester, avoiding the discomfort and aesthetic impact caused by pilling. Furthermore, its modulus is reduced by 20% compared to ordinary polyester of the same specification, significantly improving the fabric's softness.

[0018] Furthermore, the length of hemp fibers is 16-20mm.

[0019] Furthermore, the length of long-staple cotton is 20-40mm.

[0020] Furthermore, the yarn specifications are intertwined yarn, with an S-twist direction, a twist of 32-40 twists / cm, and a count of 25-30 after intertwining.

[0021] Furthermore, the weaving structure used is a plain weave.

[0022] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0023] (1) The composite outer layer and composite inner layer of this utility model are made of cotton-hemp yarn blended and then blended with polyester. First, long-staple cotton and hemp yarn are blended to obtain a yarn that is firm, smooth, and softer than pure hemp fiber. Then, cotton-hemp staple yarn is alternately interwoven with polyester filament to obtain a blended yarn, which is used as the material for weaving the composite outer layer and composite inner layer. The final fabric combines the advantages of hemp, cotton, and polyester, and the resulting fiber fabric is moderately soft and hard, smooth and wrinkle-free, has a good luster, and is skin-friendly and breathable.

[0024] (2) This invention incorporates three tightly fitted inner layers between the composite outer layer and the composite inner layer. The multi-layered outer layer is a blend of hemp and polyester, the pure hemp antibacterial layer is made of hemp fiber loaded with antibacterial materials, and the polyester stiffening layer is made of polyester. From the multi-layered outer layer through the pure hemp antibacterial layer to the polyester stiffening layer, the hemp content in the fabric fibers first increases and then decreases, while the polyester content first decreases and then increases. In the design process, the composite outer layer, made from the materials of this invention, is the outermost layer, and the composite inner layer is the inner side of the fabric closest to the user's skin. Therefore, placing more hemp-containing raw materials on the outer side of the body increases the dilution and perspiration-wicking effect, while placing more soft polyester materials on the inner side of the body ensures smoothness and comfort.

[0025] (3) The composite outer layer and composite inner layer of this utility model are made of polyester filament and cotton-hemp short fiber blended yarn. The raw materials are Xinjiang long-staple cotton and hemp blended yarn and iterated polyester filament, which have the characteristics of moisture absorption, sweat wicking, deodorization, lightness, softness and skin-friendly.

[0026] (4) This invention selects nano-silver particles as the antibacterial material on hemp fibers. By utilizing the natural antibacterial properties of nano-silver, the number of live bacteria is reduced as much as possible, thus ensuring the antibacterial properties of the fabric. In rainy seasons or during exercise and sweating, even in environments with high humidity and full of sweat, the fabric can reduce moisture accumulation and inhibit bacteria, ensuring the cleanliness of the material's interior.

[0030] To enable those skilled in the art to more clearly understand the technical solutions of this application, the technical solutions of this application will be described in detail below with reference to specific embodiments. It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains.

[0031] See attached document Figure 1As shown, this utility model embodiment provides a moisture-wicking, skin-friendly, and comfortable cotton-hemp-polyester knitted fabric, including a main fabric body. The main fabric body includes a pure hemp antibacterial layer 3 and two sides thereof: a multi-hemp outer layer 2 and a polyester stiffening layer 4; a composite surface layer 1 on the other side of the multi-hemp outer layer 2 and a composite inner layer 5 on the other side of the polyester stiffening layer 4; the composite surface layer 1 and composite inner layer 5 are made of cotton-hemp yarn blended and then blended with polyester; the multi-hemp outer layer 2 is made of hemp and polyester blended; the pure hemp antibacterial layer 3 is made of hemp fiber loaded with antibacterial material, and the polyester stiffening layer 4 is made of polyester. The antibacterial material loaded on the hemp fiber in the pure hemp antibacterial layer 3 is nano-silver particles. The weaving structure used is a plain weave, and the raw materials used can be single-material yarns or interwoven composite yarns prepared from different raw materials, see [link to details]. Figure 2 .

[0032] Specifically, regarding the weaving of the composite outer layer 1 and the composite inner layer 5, the raw material selection is as follows: the semi-dull 100D / 144F white iterative polyester filament is used in the polyester filament and cotton-hemp staple fiber blended composite yarn of this utility model; the Xinjiang long-staple cotton with a length of about 30mm and good quality is selected in the cotton-hemp staple fiber blended yarn to improve the comfort of the product; the hemp fiber with a length of 18mm is selected as high-quality long fiber; the yarn is ring spun, the count is selected as 57s, the twist direction is Z twist, and the twist degree is selected as 100 twists / 10cm.

[0033] Yarn specification design: To ensure smooth knitting, considering all factors, an interlaced structure yarn was selected, the structure of which is as follows: Figure 1 The twist direction is S-twist, the twist is 32-40 twists / cm, and the count after interlacing is 27. The overall composition of the yarn is 38.5% long-staple cotton, 9.5% hemp, and 52% polyester.

[0034] The yarn has an intertwined structure and is woven by knitting. The weaving process can be divided into one-piece forming machine weft knitting or ordinary weft knitting circular machine weaving followed by sewing. The weaving structure used is weft plain knit. The dyeing and finishing adopts a special mercerizing dyeing and finishing technology. The specific process is as follows: pre-forming of greige fabric - singeing - hydrogen peroxide pre-bleaching - etching - dyeing - finishing - setting and pre-shrinking.

[0035] Fabric pre-setting: Temperature 180-200℃, to fully set the polyester filaments in the fabric, stabilize the shape and structure of the polyester filaments, and increase the elasticity of the fabric.

[0036] Singeing: Double-sided singeing initially removes surface fuzz and reduces the itching sensation when wearing the fabric.

[0037] Hydrogen peroxide pre-bleaching: Using 5-10g / L of hydrogen peroxide and degreasing agents, treat at 100℃ for 40-60 minutes to clean surface impurities. Oxygen bleaching is relatively gentle and generally will not damage the fabric, maintaining the soft and comfortable feel of the fabric and making the color of the bleached fabric brighter.

[0038] Embossing: Also known as biopolishing, this process uses polishing enzymes at 0.5-1.5g / L, treated at 50-55℃ for 40-60 minutes to improve fabric smoothness, further remove surface fuzz, and comprehensively enhance the quality and feel of the finished garment. The treated fabric has a smooth and comfortable feel, similar to mercerized cotton.

[0039] Dyeing: Dyeing is carried out according to color requirements: For blended fabrics, cotton and linen are dyed first, neutralized and washed, and then polyester is dyed. After dyeing, the fabric is neutralized, washed, and removed from the dyeing vat.

[0040] Post-treatment: Add appropriate amounts of softener and hydrophilic cooling silicone oil according to the fabric's dyeing feel to further improve the fabric's softness. At the same time, the cooling silicone oil gives the fabric a cool feel, good elasticity, softness, silkiness, and strong drape.

[0041] Pre-shrunking after setting: To achieve a certain level of stability, the setting temperature is 180℃-200℃, the width is 150cm, and the speed is 20m-28m / min. This eliminates accumulated stress and strain in the fabric, improves the dimensional thermal stability of the fabric, reduces shrinkage, eliminates wrinkles, improves wrinkle resistance, and also improves elasticity and hand feel. Pre-shrinking after finishing: The fabric is pre-shrinked using a pre-shrinking machine, employing water washing or steam pre-shrinking methods to reduce shrinkage after washing and improve the dimensional stability of the fabric.

[0042] The composite outer layer 1 and composite inner layer 5 of this invention are made by blending cotton-hemp yarn and then polyester. First, long-staple cotton and hemp yarn are blended to obtain a yarn that is strong, smooth, and softer than pure hemp fiber. Then, cotton-hemp staple yarn is alternately interwoven with polyester filament to obtain a blended yarn, which is used as the material for weaving the composite outer layer 1 and composite inner layer 5. The final fabric combines the advantages of hemp, cotton, and polyester, resulting in a fiber fabric that is moderately soft and firm, smooth and wrinkle-free, with good luster, and is skin-friendly and breathable.

[0043] This invention incorporates three tightly fitted inner layers between the composite outer layer 1 and the composite inner layer 5. The outermost layer 2 is a blend of hemp and polyester; the antibacterial pure hemp layer 3 is made of hemp fiber loaded with antibacterial materials; and the stiffening polyester layer 4 is made of polyester. From the outermost layer 2 through the antibacterial pure hemp layer 3 to the stiffening polyester layer 4, the hemp content in the fabric fibers first increases and then decreases, while the polyester content first decreases and then increases. In the design process, the composite outer layer 1, made of the materials of this invention, is the outermost layer, and the composite inner layer 5 is the innermost layer of the fabric closest to the user's skin. Therefore, placing more hemp-containing raw materials on the outer side of the body increases the dilution and perspiration-wicking effect, while placing more soft polyester material on the inner side of the body ensures smoothness and comfort.

[0044] For the composite outer layer 1 and composite inner layer 5, the raw materials for the composite yarn made of polyester filament and cotton-hemp staple fiber blended yarn are Xinjiang long-staple cotton and hemp blended yarn from my country, along with iterated polyester filament, which have the characteristics of moisture absorption, perspiration wicking, odor prevention, lightness, softness, and skin-friendliness. Nano-silver particles are selected as the antibacterial material on the hemp fibers. Utilizing the natural antibacterial properties of nano-silver, the number of viable bacteria is minimized, ensuring the fabric's antibacterial properties. In rainy seasons or during exercise and sweating scenarios, even in high-humidity environments filled with sweat, the fabric can reduce moisture accumulation and inhibit bacteria, ensuring the cleanliness of the material's interior.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
