Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of textile fabrics, in particular to a heat-generating far-infrared warm-keeping woven fabric. Background Art
[0002] A fabric with longitudinal, transverse, or diagonal ridges on the front and weft or warp floats on the back is called a ridge weave. A ridge weave is composed of a weft-heavy plain weave with long floats and another simple weave. The simple weave acts as a anchoring structure, forming the front of the fabric, hence the name "anchoring structure." For example, anchoring the weft-heavy plain floats creates longitudinal ridges, while anchoring the warp-heavy plain floats creates transverse ridges. In ridge weaves, the floats of the plain weave, the base weave, should not be less than four weave points long. Short floats make the ridges less noticeable. Commonly used weaves include plain weave, 1 / 2 twill, and 2 / 1 twill. Plain-heavy, anchored ridge weaves are the most widely used in production. The degree of ridge is influenced by the floats of the base weave and yarn tension, as well as the fabric density. The floats are long and the ridges are prominent. The tension of the yarns that form the floats in the ridge weave is increased, and the ridges are prominent. The fabric density is high, especially the density of the yarns that form the ridges, and the ridge effect is obvious.
[0003] Currently, common ribbed weaves are made from pure cotton ring-spun yarn, polyester-cotton ring-spun blended yarn, or stretch yarn. Due to the structural characteristics of ribbed weave, selecting different yarns is more economical and maximizes its advantages. Furthermore, currently available wicking weaves generally lack functionality. By creating a functional ribbed weave and improving its warmth retention, it could be used in autumn and winter clothing, offering promising market prospects. Utility Model Content
[0004] In response to the shortcomings of existing woven fabrics, this application provides a heat-generating far-infrared thermal insulation woven fabric. This application utilizes the structural characteristics of the ribbed structure and selects yarns with different structures and functions to construct the ribbed structure. It has heat-generating and far-infrared functions, and is more economical and practical, and can be used for autumn and winter clothing.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A heat-generating far-infrared warm-keeping woven fabric has a longitudinal convex stripe structure and a weave loop consisting of sixteen warp yarns, four core yarns and four weft yarns. The warp yarns are polyester yarns, the core yarns are rotor-spun pure cotton yarns, the first and third weft yarns are far-infrared pure cotton stretch yarns, and the second and fourth weft yarns are heat-generating pure cotton stretch yarns.
[0007] In the embodiment of the present application, the core thread is located between the longitudinal ribs and the float threads formed by the weft yarns.
[0008] In the embodiment of the present application, the far-infrared pure cotton stretch yarn is a pure cotton stretch yarn finished with a far-infrared finishing agent.

[0010] In an embodiment of the present application, the pure cotton stretch yarn is a pure cotton spandex core-spun yarn structure.
[0011] Compared to the existing technology, the present invention provides a heat-generating, far-infrared, and warm-keeping woven fabric with a longitudinal convex stripe structure. The fabric consists of sixteen warp yarns, four core yarns, and four weft yarns, forming a single loop. The warp yarns are polyester yarns, the core yarns are rotor-spun pure cotton yarns, the first and third weft yarns are far-infrared pure cotton stretch yarns, and the second and fourth weft yarns are heat-generating pure cotton stretch yarns.

BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 This is a schematic diagram of the warp-wise cross-sectional structure of a heat-generating far-infrared thermal insulation woven fabric provided by the utility model. DETAILED DESCRIPTION
[0013] The following will clearly and completely describe the technical solution of the present invention through specific implementation methods. Obviously, the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0014] In the description of this application, it should be understood that terms such as "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", and "outside" indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on this application.
[0015] The present application provides a heat-generating far-infrared thermal insulation woven fabric with a longitudinal convex stripe structure. A tissue loop is formed by sixteen warp yarns, four core yarns and four weft yarns. The warp yarns are polyester yarns, the core yarns are rotor-spun pure cotton yarns, the first weft yarns and the third weft yarns are far-infrared pure cotton stretch yarns, and the second weft yarns and the fourth weft yarns are heat-generating pure cotton stretch yarns.
[0016] The woven fabric provided by the present application has heating and far-infrared functions, and is a more economical and practical ribbed structure.
[0017] See also Figure 1 , Figure 1 Figure 1 illustrates the yarn arrangement of the fabric structure from the warp cross-section direction, where 1 is the first warp yarn, 2 is the second warp yarn, 3 is the third warp yarn, 6 is the sixth warp yarn, 7 is the seventh warp yarn, 8 is the eighth warp yarn, 9 is the ninth warp yarn, 10 is the tenth warp yarn, 11 is the eleventh warp yarn, 12 is the twelfth warp yarn, 13 is the thirteenth warp yarn, 16 is the sixteenth warp yarn, 17 is the seventeenth warp yarn, 18 is the eighteenth warp yarn, 19 is the nineteenth warp yarn, 20 is the twentieth warp yarn, 4 is the first core yarn, 5 is the second core yarn, 14 is the third core yarn, 15 is the fourth core yarn, 21 is the first weft yarn, 22 is the second weft yarn, 23 is the third weft yarn, and 24 is the fourth weft yarn.
[0018] It should be pointed out that in order to more clearly illustrate the weft yarn weaving situation, the drawings use lines of different widths to indicate the weft yarns, so that the weft yarns can be easily distinguished. The different widths of the weft yarn lines in the drawings do not mean that the linear density of the weft yarns is different.
[0019] See also Figure 1As shown, a heat-generating far-infrared thermal insulation woven fabric has a longitudinal convex stripe structure and is composed of sixteen warp yarns, four core yarns, and four weft yarns forming a weave loop. The warp yarns are polyester yarns, and the core yarns are rotor-spun pure cotton yarns. The first weft yarn 21 and the third weft yarn 23 are far-infrared pure cotton stretch yarns, and the second weft yarn 22 and the fourth weft yarn 24 are heat-generating pure cotton stretch yarns. The sixteen warp yarns are respectively the first warp yarn 1, the second warp yarn 2, the third warp yarn 3, the sixth warp yarn 6, the seventh warp yarn 7, the eighth warp yarn 8, the ninth warp yarn 9, the tenth warp yarn 10, the eleventh warp yarn 11, the twelfth warp yarn 12, the thirteenth warp yarn 13, the sixteenth warp yarn 16, the seventeenth warp yarn 17, the eighteenth warp yarn 18, the nineteenth warp yarn 19, and the twentieth warp yarn 20. The four core yarns are respectively the first core yarn 4, the second core yarn 5, the third core yarn 14, and the fourth core yarn 15. Due to the structural characteristics of the longitudinal ribbed weave and the presence of a core yarn between the ribbed and floated yarns, more weft yarn is visible on the reverse side of the fabric, while less warp yarn is visible. Therefore, the warp is made of non-functional, conventional yarn, while the weft is made of yarn with far-infrared and heat-generating properties, making it easier to utilize its functional properties. Similarly, the weft and core yarns are made of cotton yarn, while the warp is made of polyester yarn. The presence of more cotton yarn on the reverse side provides greater comfort for the wearer. The weft is a stretch yarn, while the warp is a conventional yarn. The elasticity of the weft direction promotes a close-fitting, warm fit. The core yarn is located between the ribbed and floated yarns. The core yarn is rotor-spun, while the warp is ring-spun. This gives the core yarn a fuller, thicker feel and improved warmth retention. Rotor-spun cotton yarn is also less expensive than ring-spun cotton yarn.
[0020] In the embodiments of this application, the core yarn is located between the longitudinal ribs and the weft floats. In actual production, for longitudinal rib weaves, two weft floats of equal length are often brought together, and then a bonding weave is applied to the weft floats. Sometimes, to increase the raised profile of the ribs, two plain weave warp yarns are inserted between the two ribs, or several thicker yarns are added to the center of the ribs as a core yarn. The core yarn is located below the ribs and above the weft floats. It does not interweave with any weft yarns and serves only as a cushion, allowing the use of inferior raw materials.
[0021] Open-end spinning involves separating fibers into individual strands and agglomerating them, twisting them into yarn without mechanically holding one end. Typical examples include rotor spinning, electrospinning, vortex spinning, vortex air-jet spinning, and friction spinning. Rotor yarn, formerly known as open-end spinning, is produced by using the centrifugal force generated by the high-speed rotor to cause the fibers to agglomerate in a coagulation trough surrounding the rotor, where they are then twisted by the rotor. The structural characteristics of open-end spinning are large interstices, poor fiber straightness, minimal fiber transfer between the inner and outer layers, and uneven twist. Consequently, the yarn has low strength and high elongation. However, the fabric has a full, thick feel, excellent warmth retention, abrasion resistance, good sizing and moisture absorption, and high color absorption. Rotor-spun yarn is relatively affordable and suitable for a wide range of products, such as corduroy, denim, khaki, yarn-dyed velvet, printed velvet, blankets, yarn rugs, bath towels, and decorative fabrics.
[0022] The core thread can be made of inferior raw materials, while rotor-spun yarn is cheap. At the same time, rotor-spun yarn feels plump and thick and has good warmth retention, which makes it easier to improve the warmth retention of this application. Therefore, the core thread uses rotor-spun yarn.
[0023] In the embodiments of this application, the far-infrared pure cotton stretch yarn is treated with a far-infrared finishing agent. Far-infrared textiles are made by combining functional materials that emit far-infrared rays with textiles to impart far-infrared properties. This is generally achieved through two methods: one is through post-finishing technology, where far-infrared micropowder, solvent-based adhesives, and additives are mixed in a certain proportion to form a far-infrared finishing agent. This is then combined with the far-infrared finishing agent through post-finishing methods such as impregnation, padding, coating, or spraying to impart far-infrared properties to the textile. In this application, the far-infrared pure cotton stretch yarn is produced using a far-infrared finishing agent and impregnation finishing methods known in the art.
[0024] In a preferred embodiment of the present application, the far-infrared finishing agent can be the functional finishing agent FRA210 from Shanghai Hut Chemical Co., Ltd. or the nano-negative ion powder JLSUN900 from Beijing Jieershuang High-Tech Co., Ltd. The nano-negative ion powder JLSUN900 primarily contains nano-far-infrared ceramic radiators, nano-negative ion tourmaline powder, a dispersion, a protective agent, and the like. Fabrics treated with the nano-negative ion powder JLSUN900 can be processed using processes such as printing, spinning, and impregnation. The functional finishing agent FRA210, containing the essence of tourmaline tourmaline, releases a spectrum of far-infrared rays upon stimulation, offering versatility, a short one-step process, simple operation, and a long storage stability period. It is widely applicable to natural fiber fabrics containing amino or hydroxyl groups, such as cotton, linen, silk, and wool, as well as polyester and nylon fabrics. The finished fabrics can be widely used in sportswear, outerwear, underwear, bedding, and health textiles. Functional finishing agent FRA210 can be used to treat fabrics by padding, dipping and coating processes. The general dosage is 4-5% (owf). The specific dosage and usage depend on the type of fabric.
[0025] In exhaust dyeing, the ratio of the dye liquor mass to the mass of the substrate is called the bath ratio. Since the dyeing medium is generally water, the bath ratio is usually expressed as the ratio of the dye liquor volume (L) to the mass of the substrate (kg). Dye dosage is generally expressed as a percentage of the fiber weight (owf), also known as dye concentration. When using the impregnation method for functional finishing, the bath ratio is usually expressed as the ratio of the finishing agent mass to the substrate mass. The finishing agent dosage is also generally expressed as a percentage of the fiber weight (owf).
[0026] In a preferred embodiment of the present application, the pure cotton stretch yarn is a pure cotton spandex core-spun yarn. Spandex has a wide range of applications, with bare spandex yarn primarily used in tights, sportswear, leggings, surgical bandages, sock cuffs, and cuffs. Although spandex can be directly woven into stretch fabrics, in practice, spandex is often used as the core yarn, with cotton, wool, silk, or various synthetic fibers wrapped around it to create core-spun yarn, sheathed yarn, wrapped yarn, and twisted yarn, which are then woven into stretch fabrics. Different stretch yarns differ in elasticity, strength, and color-matching properties, so different twisted yarns are suitable for different types of textiles, specifically, different spandex-containing textiles. Core-spun yarns use spandex as the core yarn, sheathed with one or more non-elastic staple fibers. Yarns with natural fibers as the outer sheath fibers have excellent moisture absorption. Furthermore, due to this sheathing, the core yarn is generally not exposed during stretching, resulting in improved comfort. Furthermore, when dyeing dark-colored products, the lighter color of the spandex prevents the color-matching properties from being affected. However, the strength of core-spun yarn is relatively low. Generally, the strength of a single yarn is only 80-90% of the yarn made from the same specification of outer fiber alone.
[0027] In a further preferred embodiment of the present application, the pure cotton stretch yarn is a core-spun yarn composed of 98% cotton by mass and 2% spandex by mass, which is a common pure cotton spandex core-spun yarn in the art.
[0028] In the embodiments of this application, the heat-generating pure cotton stretch yarn is treated with a thermal finish. Thermal fabrics are an emerging functional textile that can increase the perceived temperature of the human body and offer a pleasant hand feel and excellent wash fastness. Scientific and technical data confirm that chamomile extract and the fat-burning agent tangerine peel can promote blood circulation, generate heat and warmth, increase skin warmth, and relieve joint pain. They also nourish and moisturize the skin, leaving it healthy, elastic, and radiant, and providing excellent protection for the skin. Technical data also indicates that the fat-burning agent can effectively aid in fat decomposition. In this application, the heat-generating pure cotton stretch yarn is produced using a thermal finish and impregnation finishing method known in the art.
[0029] In a preferred embodiment of this application, the thermal finish can be WARM6032 from Shanghai Hut Chemical Co., Ltd. or HOTF from Beijing Jieershuang High-Tech Co., Ltd. HOTF is suitable for fabric finishing and can be used alone or in combination with softeners and resins. It can be applied by dipping, padding, or spraying. The dosage is typically 3-5% (owf) (i.e., 4-6 grams per 100 grams of dry fabric). It is easy to use. WARM6032 is a thermal finish suitable for natural fibers such as cotton and wool, and their blends. Fabrics treated with WARM6032 experience a warming sensation, moisturize the skin, and offer excellent warmth retention and breathability. They are comfortable, soft, and maintain their effectiveness even after repeated washings. WARM6032 can be applied by padding, dipping, or coating. The typical dosage is 3-5% (owf). The specific application method and dosage depend on the type, variety, and intended use of the fabric.
[0030] The surface density, i.e., the mass per unit area, of all fabrics, including woven fabrics, knitted fabrics, braided fabrics, and non-woven fabrics, is uniformly defined as the mass per unit area at the standard moisture regain, with the unit being g / m2.
[0031] Linear density refers to the mass per unit length of fiber, single yarn, mesh cable, rope, etc., and is an indicator of the thickness of the yarn; the higher the linear density, the thicker the fiber or yarn. Tex, abbreviated as tex, refers to the weight in grams of 1000 meters of fiber or yarn at the standard moisture regain and is the unit of linear density for fixed-length systems; tex is commonly known as the number for cotton yarn. Denier (D, short for denier) refers to the weight in grams of a 9000-meter-long fiber bundle; the linear density of a yarn can also be expressed by its diameter. The linear density of a chemical fiber multifilament is generally expressed by the number of individual filaments and the total tex number, such as: 16.5tex / 30f, indicating a total multifilament density of 16.5tex and 30 individual filaments.
[0032] The linear density is mainly determined by metric count (N) and imperial count (S); among them, imperial count refers to the length of yarn per unit weight (1 pound) at the standard regain rate as a multiple of 840 yards. The larger the count, the thinner the yarn.
[0033] Thermal finishing of textiles has been widely used for many years, but there is no corresponding testing standard in the current standards. In the present utility model, the testing method for the heat-generating and heat-insulating properties of textiles is to first place the test sample for 24 hours in an environment with a temperature of 18°C and a humidity of 65%. Then the tester exposes both lower arms for 30 minutes, and uses an infrared thermometer to test the temperature of the left and right lower arms respectively. After that, the left and right lower arms are respectively covered with a single layer of the sample of the embodiment and the comparative example for 20 minutes. Then the samples are removed and the temperature of the left and right lower arms is measured again with an infrared thermometer. The temperature rise value of the embodiment is the difference between the temperature after the embodiment is covered and the temperature before the embodiment is covered. The temperature rise value of the comparative example is the difference between the temperature after the comparative example is covered and the temperature before the comparative example is covered. The temperature rise value of the embodiment relative to the comparative example is expressed by the difference between the temperature rise value of the embodiment and the temperature rise value of the comparative example.
[0034] In summary, this application utilizes the structural characteristics of the ribbed tissue and selects yarns with different structures and functions to construct the ribbed tissue, which has heat generation and far-infrared functions, and is more economical and practical, and can be used for autumn and winter clothing.
