Description

Technical Field

[0001] This utility model relates to the field of textile fabric technology, specifically to a cool and breathable woven fabric. Background Technology

[0002] Bast fibers originate from the bast layer of the stems of hemp plants. The fiber bundles are relatively soft and are also known as soft fibers. Bast fibers are mostly found in dicotyledonous herbaceous fabrics, primarily ramie, flax, jute, and hemp. Ramie, a specialty of my country, is hailed worldwide as "China's grass, China's treasure." Ramie fiber's moisture absorption and breathability are about 3-5 times that of cotton fiber, and it also contains beneficial elements such as benzoyl peroxide, pyrimidine, and purine, making it a globally recognized "king of natural fibers." Ramie fiber fabrics are textiles with antibacterial, breathable, cooling, anti-corrosion, mildew-proof, and sweat-absorbing properties.

[0003] However, ramie fibers are stiff and rigid, with a high initial modulus. Therefore, during ramie spinning, the cohesion between fibers is weak, resulting in a lot of yarn hairiness. Although ramie fibers have high strength and rigidity, their elongation and breaking energy are low. Furthermore, ramie fibers have poor elastic recovery, leading to poor wrinkle resistance and abrasion resistance in ramie fabrics.

[0004] Perforated weave is a fabric structure composed of plain weave, plain weave variations, or a combination of two plain weave variations. Fabrics woven with this structure have uniformly distributed small pores on their surface, similar to leno weave, hence the name perforated weave or pseudo-leno weave. Perforated weaves are commonly used in lightweight fabrics such as cotton, linen, and silk, and are generally used for thin summer clothing, primarily due to their porous, lightweight, cool, and breathable characteristics. Examples include various mesh fabrics and fancy perforated fabrics. They are also used in the production of screen fabrics and in lightweight woolen fabrics.

[0005] Linen fabrics with perforated structures are more suitable for summer use. However, linen fabrics have poor wrinkle resistance and abrasion resistance, and are prone to causing itching during wear, affecting wearing comfort and making them difficult to care for. Utility Model Content

[0006] To address the shortcomings of existing woven fabrics, this application provides a cool-feeling and breathable woven fabric and woven textile.

[0007] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a cool and breathable woven fabric that not only has the properties of coolness, breathability and moisture permeability, but also has good abrasion resistance, wrinkle resistance and moisture wicking.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A cool-feeling and breathable woven fabric has a perforated structure and is composed of a first yarn and a second yarn. The first yarn is a cool-feeling and moisture-wicking polyester yarn, and the second yarn is a ramie yarn. The linear density of the first yarn is greater than that of the second yarn.

[0010] In the embodiments of this application, the number of weave repeats in the perforated structure is any one of 6, 8, 10, and 14. The number of weave repeats can be 6, in which the first warp, third warp, fourth warp, sixth warp, first weft, third weft, fourth weft, and sixth weft are second yarns, and the second warp, fifth warp, second weft, and fifth weft are first yarns.

[0011] In the embodiments of this application, the linear density of the first yarn is not less than 1.2 times the linear density of the second yarn.

[0012] In the embodiments of this application, the cooling and moisture-wicking polyester yarn is a profiled polyester fiber yarn that has undergone cooling treatment, and the profiled polyester fiber yarn may be a yarn composed of Y-shaped profiled polyester fibers.

[0013] This application also provides a woven textile for summer clothing made from the woven fabric described above.

[0014] Compared with existing technologies, this utility model provides a cool-feeling and breathable woven fabric with a perforated structure, composed of a first yarn and a second yarn. The first yarn is a cool-feeling and moisture-wicking polyester yarn, and the second yarn is ramie yarn. The linear density of the first yarn is greater than that of the second yarn. This application uses functional profiled fiber yarns and ramie yarn in a certain arrangement ratio to construct a woven fabric with a perforated structure, thus developing a woven fabric with cool-feeling, breathable, and moisture-wicking properties, while also possessing good abrasion resistance, wrinkle resistance, and moisture wicking. Attached Figure Description

[0015] Figure 1 This is a structural schematic diagram of a cool-feeling and breathable woven fabric provided by this utility model. Detailed Implementation

[0016] The technical solution of this utility model will now be clearly and completely described through specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., which indicate orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, 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, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0018] This application provides a cool-feeling and breathable woven fabric with a perforated structure, consisting of a first yarn and a second yarn. The first yarn is a cool-feeling and moisture-wicking polyester yarn, and the second yarn is ramie yarn. The linear density of the first yarn is greater than that of the second yarn.

[0019] The woven fabric provided in this application not only has a cooling sensation and breathable and moisture-wicking properties, but also has good abrasion resistance, wrinkle resistance and moisture-wicking properties.

[0020] See Figure 1 , Figure 1 This is a schematic diagram of the structure of the cool-feeling and breathable woven fabric provided in the embodiments of this application, wherein A is the first yarn, B is the second yarn, 1 is the first warp yarn, 3 is the third warp yarn, 4 is the fourth warp yarn, 6 is the sixth warp yarn, 7 is the first weft yarn, 9 is the third weft yarn, 10 is the fourth weft yarn, 12 is the sixth weft yarn, 2 is the second warp yarn, 5 is the fifth warp yarn, 8 is the second weft yarn, 11 is the fifth weft yarn, and 13 is the eyelet.

[0021] See Figure 1 As shown, the cool-feeling, breathable woven fabric has a perforated structure, composed of a first yarn A and a second yarn B. First yarn A is a cool-feeling, moisture-wicking polyester yarn, and second yarn B is ramie yarn. The linear density of first yarn A is greater than that of second yarn B. This cool-feeling, breathable, antibacterial, and comfortable woven fabric, with its perforated structure, possesses excellent breathability and moisture permeability, resulting in good comfort. Because the linear density of first yarn A is greater than that of second yarn B, during wear, first yarn A, due to its higher linear density, is more likely to come into contact with the skin and the external environment, while second yarn B, with its lower linear density, has relatively less contact with the skin and the external environment, reducing itching. Since ramie yarn has poor abrasion resistance and wrinkle resistance, while polyester yarn has good abrasion resistance and wrinkle resistance, the higher density of first yarn A can improve the fabric's abrasion resistance and wrinkle resistance. Second yarn B, being ramie yarn, has antibacterial and moisture-wicking properties, easily absorbing sweat from the skin surface and reducing bacterial growth. The first yarn A is a cool-feeling, moisture-wicking polyester yarn, which can improve the cool-feeling performance of this application.

[0022] The areal density, or mass per unit area, of all fabrics, including woven fabrics, knitted fabrics, braided fabrics, and nonwoven fabrics, is uniformly defined as the mass per unit area under the standard moisture regain, with the unit being g / m2.

[0023] The ratio of the mass of the dye liquor to the mass of the fabric being dyed during dyeing is called the liquor ratio. Since the dyeing medium is generally water, the ratio of the volume of the dye liquor (L) to the mass of the fabric being dyed (kg) is conventionally called the liquor ratio. The amount of dye used is generally expressed as a percentage of the fiber mass (owf), which is called the dyeing concentration. When using the impregnation method for functional finishing, the ratio of the mass of the finishing agent to the mass of the fabric being finished is usually called the liquor ratio. The amount of finishing agent used is also generally expressed as a percentage of the fiber mass (owf).

[0024] Linear density refers to the mass per unit length of fiber, single yarn, netting, rope, etc., and is an indicator describing the fineness of the yarn; the higher the linear density, the thicker the fiber or yarn. Tex (tex) is the weight in grams of 1000 meters of fiber or yarn at standard moisture regain; it is a unit of linear density in a fixed-length system. For cotton yarns, tex is commonly referred to as the yarn number. Denier (D) refers to the weight in grams of a 9000-meter fiber bundle; the linear density of yarn can also be expressed using diameter. The linear density of multifilament chemical fibers is generally expressed by the number of single filaments and the total tex count, such as 16.5tex / 30f, which means the total linear density of the multifilament is 16.5tex and the number of single filaments is 30.

[0025] Linear density is mainly measured in metric count (N) and imperial count (S). Imperial count refers to the number of times that the length of yarn per unit weight (1 pound) at standard moisture regain is a multiple of 840 yards. The higher the count, the finer the yarn.

[0026] In the embodiments of this application, the number of tissue cycles in the porous structure is any one of 6, 8, 10, or 14. This type of porous structure is a common porous structure in the art and is easy to produce.

[0027] In the embodiments of this application, the number of weave cycles is 6. In one weave cycle, the first warp 1, the third warp 3, the fourth warp 4, the sixth warp 6, the first weft 7, the third weft 9, the fourth weft 10, and the sixth weft 12 are the second yarn B, and the second warp 2, the fifth warp 5, the second weft 8, and the fifth weft 11 are the first yarn A. The cause of fabric porosity formation is now explained. Figure 1It can be seen that the third warp yarn 3, the fourth warp yarn 4, and the sixth warp yarn 6 are all interwoven with the first warp yarn 1 in a plain weave, with their warp and weft points opposite. Therefore, the third and fourth warp yarns and the sixth warp yarn and the first warp yarn do not easily come together. Furthermore, under the action of the floats of the second weft yarn 8 and the fifth weft yarn 11, the first warp yarn 1, the second warp yarn 2, and the third warp yarn 3 are brought together, as are the fourth warp yarn 4, the fifth warp yarn 5, and the sixth warp yarn 6. Therefore, longitudinal gaps are formed between the third warp yarn 3 and the fourth warp yarn 4, and between the sixth warp yarn 6 and the first warp yarn 1. Similarly, transverse gaps are formed between the third weft yarn 9 and the fourth weft yarn 10, and between the sixth weft yarn 12 and the first weft yarn 7. This creates perforations on the fabric surface, such as… Figure 1 As shown, 13 is the location where the hole is formed.

[0028] In the embodiments of this application, the linear density of the first yarn A is not less than 1.2 times the linear density of the second yarn B. In a preferred embodiment of this application, the linear density of the first yarn A is 21S, and the linear density of the second yarn B is 32S.

[0029] In the embodiments of this application, the cooling and moisture-wicking polyester yarn is a profiled polyester fiber yarn that has undergone a cooling treatment. Therefore, the first yarn A possesses cooling and moisture-wicking properties.

[0030] In a preferred embodiment of this application, the cooling finish employs a known impregnation finishing method and a known cooling finishing agent. Preferably, the cooling finishing agent is EHC, an exothermic cooling finishing agent, or T802, a temperature-regulating finishing agent from Beijing Jieershuang High-Tech Co., Ltd. EHC, the exothermic cooling finishing agent, contains xylitol and highly exothermic material nanocapsules, which can quickly release heat from the skin and clothing, providing a cool and comfortable wearing experience. Simultaneously, by reducing perspiration, it keeps clothing dry and flowing, like a refreshing symphony of green mint. It is suitable for exothermic cooling finishing of natural and synthetic fiber fabrics and can be achieved using impregnation and padding processes. T802, the temperature-regulating (cooling) finishing agent (PCM cooling phase change microcapsules), is an automatically temperature-regulating microcapsule with higher alkanes as its main component. Its phase change temperature is 28°C. When the external temperature reaches the phase change temperature, T802 undergoes a phase change, absorbing or releasing heat to regulate the temperature of the textile fabric, providing a comfortable feeling. The phase change material of temperature-regulating (cooling) finishing agent T802 gradually changes from solid to liquid when the external temperature rises to its phase change temperature, absorbing external heat and storing it as latent energy. Once the external temperature decreases, it gradually solidifies, releasing its latent energy, thus buffering the temperature rise and fall of the fabric surface. Temperature-regulating finishing agent T802 is suitable for fabric finishing and can be used alone or in combination with softeners and resins. It can be applied through processes such as impregnation, padding, and spraying.

[0031] Shaped fibers, as opposed to circular fibers, are fibers with non-circular cross-sectional shapes processed using non-circular spinneret orifices. In a preferred embodiment of this application, the shaped polyester fiber yarn is a yarn composed of Y-shaped shaped polyester fibers. The polyester fibers with shaped cross-sections have a grooved surface structure, resulting in excellent wicking effect, accelerating moisture conduction and evaporation, and keeping the fabric dry. Its low moisture regain rate minimizes the absorption of moisture from the air, keeping the fabric feeling dry to the touch.

[0032] In summary, this application mainly utilizes functional profiled fiber yarns and ramie yarns in a certain arrangement ratio to construct a woven fabric using a perforated structure. This results in a woven fabric with cooling, breathable, and moisture-wicking properties, while also exhibiting good abrasion resistance, wrinkle resistance, and moisture-wicking ability. This application also provides a woven textile for summer clothing using the aforementioned woven fabric.

[0033] To better understand the technical content of this application, specific embodiments are provided below to further illustrate a cool-feeling and breathable woven fabric provided in this application. In the following embodiments, all raw materials used are commercially available.

[0034] Example 1

[0035] See Figure 1 As shown, the cool-feeling and breathable woven fabric has a unit area mass of 130g / m2, a perforated structure, and a weave repeat number of 6. It is composed of a first yarn A and a second yarn B. The first yarn A is a cool-feeling and moisture-wicking polyester yarn, and the second yarn B is a ramie yarn. The linear density of the first yarn A is 21S, and the linear density of the second yarn B is 32S. In one weave repeat, the first warp 1, the third warp 3, the fourth warp 4, the sixth warp 6, the first weft 7, the third weft 9, the fourth weft 10, and the sixth weft 12 are the second yarn B, and the second warp 2, the fifth warp 5, the second weft 8, and the fifth weft 11 are the first yarn A.

[0036] The cooling and moisture-wicking polyester yarn is a Y-shaped cross-section profiled polyester fiber yarn treated with an exothermic cooling agent EHC. The finishing process is: EHC 6% owf, liquor ratio 1:10, treatment at 85℃ for 20 minutes, followed by dehydration and drying at 130℃.

[0037] Example 2

[0038] The cooling finishing agent used in Example 2 is temperature-regulating finishing agent T802, and the rest is the same as in Example 1.

[0039] Comparative Example 1

[0040] Ramie perforated woven fabric has a unit area weight of 133g / m2, with warp yarns of 32S and weft yarns of 21S.

[0041] Comparative Example 2

[0042] Ramie plain weave woven fabric has a unit area weight of 128g / m2, with warp yarns of 32S and weft yarns of 21S.

[0043] The performance test results are as follows:

[0044] According to the test results in GB / T 5453 "Determination of Air Permeability of Textile Fabrics", the air permeability of Examples 1, 2, and Comparative Example 1 is similar, but compared with Comparative Example 2, the air permeability increases by 20-25%, indicating improved air permeability. It is evident that the porous structure of this application significantly improves the air permeability of the fabric.

[0045] According to the test results in GB / T 35263 "Test and Evaluation of Instant Cooling Function of Textiles upon Contact", at a ΔT of 15℃, the cooling value of Comparative Example 1 is 0.11 J / (cm²·s), and the cooling value of Comparative Example 2 is 0.09 J / (cm²·s), which are quite close. The cooling value of Example 1 is 0.21, and the cooling value of Example 2 is 0.19. Therefore, the cooling performance of this application is significantly improved.

[0046] According to ISO 12947.2 Martindale abrasion resistance - specimen bursting method, the number of abrasion cycles for Comparative Example 1 and Comparative Example 2 were similar, and the number of abrasion cycles for Example 1 and Example 2 were close, showing an improvement of 20-23% compared to Comparative Example 1 and Comparative Example 2. Therefore, the use of the cool-feeling and moisture-wicking polyester yarn of this application, with its high linear density, significantly improves the abrasion resistance.

[0047] According to AATCC 135 Dimensional Changes of Fabrics After Household Washing, after 5 washes at 60°C, and according to AATCC 128-2004 Wrinkle Recovery of Fabrics: Appearance Method, Comparative Example 1 and Comparative Example 2 were both Grade 1, and Example 1 and Example 2 were both Grade 2. That is, the cool-feeling moisture-wicking polyester yarn of this application was used and had a high linear density, which significantly improved the wrinkle resistance level.

[0048] As can be seen from the above embodiments, this application uses two yarns with different linear densities and functions, arranged in a certain order, to construct a cool and breathable woven fabric through a perforated structure. It not only has the properties of coolness, breathability and moisture permeability, but also has good abrasion resistance, wrinkle resistance and moisture wicking.
