Description

Technical Field

[0001] This utility model relates to the field of woven fabric technology, and in particular to a moisture-absorbing and heat-generating elastic woven fabric. Background Technology

[0002] Thermal knitwear is widely used for close-fitting clothing such as knitted underwear in autumn and winter. Passive thermal insulation clothing generally prevents heat loss from the garment by controlling heat convection, radiation, and conduction within the fabric. However, this passive insulation is related to the thickness and density of the fabric, the materials and thickness of the insulation layer, and the materials and thickness of the heat-retaining layer. Therefore, thick fabrics and bulky clothing not only affect the appearance but also restrict the body's movement. Active thermal insulation materials, which introduce external heat-generating elements and generate their own heat for insulation, actively generate heat, resulting in a higher and more uniform temperature rise, a faster heating rate, better insulation, and superior comfort. Therefore, they are a hot research topic in the development of lightweight clothing fabrics for autumn and winter.

[0003] Moisture-absorbing and heat-generating fibers are a type of temperature-regulating material that absorbs moisture from water molecules moving within the microclimate of the human body and clothing, thus gaining partial heat energy. They have broad application prospects in the textile industry. Common moisture-absorbing and heat-generating fibers on the market include acrylate fibers, modified polyacrylic fibers, ultrafine denier acrylic fibers, as well as modified acrylic fibers and modified viscose. However, due to the high price of moisture-absorbing and heat-generating fibers, developing lightweight knitted fabrics with excellent moisture-absorbing and heat-generating properties through knitted structure design, fabric structural parameter design, and the rational configuration of blended yarns combining moisture-absorbing and heat-generating fibers with other fibers has a promising market application prospect.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0005] The purpose of this invention is to provide a moisture-wicking and heat-generating elastic woven fabric. By utilizing a scientific interlayer yarn configuration, a gradient combination of moisture-wicking, moisture-storing, and moisture-wicking heat-generating properties is formed. At the same time, the double-layer honeycomb structure and the outer insulation layer enhance the fabric's warmth to a certain extent. It also features good breathability, excellent one-way moisture-wicking performance, and a certain degree of elasticity, resulting in superior overall performance.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A moisture-wicking and heat-generating elastic woven fabric, characterized in that it comprises, from the inside out, an inner moisture-wicking layer, a first intermediate moisture-wicking and moisture-retaining layer, a second intermediate moisture-wicking and heat-generating layer, and an outer heat-insulating layer. The warp yarns of the moisture-wicking layer, the moisture-wicking and moisture-retaining layer, and the moisture-wicking and heat-generating layer are all polyester filaments. The weft yarns of the moisture-wicking layer are modified polyester filaments. The weft yarns of the moisture-wicking and moisture-retaining layer are viscose yarns.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. This utility model utilizes a scientific interlayer yarn configuration to form a gradient combination of moisture wicking, moisture storage, and moisture absorption and heat generation. At the same time, the double-layer honeycomb structure and the outer insulation layer improve the warmth of the fabric to a certain extent. It also features good breathability, excellent one-way moisture wicking performance, and a certain degree of elasticity, resulting in superior overall performance.

[0017] 2. This invention utilizes the differential capillary effect theory to design a multi-layered fabric structure using yarns with different compositions and linear densities to create an internal and external capillary pressure difference, thereby accelerating the moisture wicking and absorption capacity. At the same time, when moisture is transferred from the inner layer to the outer layer, the strong capillary pressure prevents the moisture from rapidly diffusing to the surface layer, thus playing a role in water storage.

[0018] 3. The honeycomb structure of this invention utilizes the interval arrangement of long and short floats to create an uneven appearance on the fabric surface. The raised parts can form channels that can accommodate a large amount of still air, thereby enabling the absorption of moisture.

[0019] 4. This utility model can effectively improve the moisture-wicking and moisture-absorbing capacity of polyester filaments with grooved surfaces. The grooves facilitate the formation of moisture-wicking channels in the fibers, thereby improving the wicking performance of the fibers. Attached Figure Description

While embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0026] The term "comprising" and its variations as used herein signify open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "at least partially based on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "first", "second", etc., may refer to different or the same objects. Other explicit and implicit definitions may also be included below.

[0027] like Figure 1The illustrated moisture-wicking and heat-generating elastic woven fabric comprises, from the inside out, an inner moisture-wicking layer 1, a first intermediate moisture-wicking and moisture-storing layer 2, a second intermediate moisture-wicking and heat-generating layer 3, and an outer heat-insulating layer 4. The warp yarns of the moisture-wicking layer 1, the moisture-wicking and moisture-storing layer 2, and the moisture-wicking and heat-generating layer 3 are all polyester filaments, the weft yarns of the moisture-wicking layer 1 are modified polyester filaments, the weft yarns of the moisture-wicking and moisture-storing layer 2 are viscose yarns, the weft yarns of the moisture-wicking and heat-generating layer 3 are a blend of cotton fiber and modified acrylic fiber, the weft yarns of the heat-insulating layer 4 are aerogel fiber filaments, and the warp yarns are cotton fibers.

[0028] like Figure 2 The moisture-wicking layer 1 and the moisture-absorbing and heat-generating layer 3 shown adopt a honeycomb structure, such as... Figure 3 The moisture-absorbing and moisture-storing layer 2 shown adopts a two-upper-two-lower right-hand diagonal pattern, as shown in the figure. Figure 4 The insulation layer 4 shown adopts a plain weave structure, and the moisture-absorbing and moisture-storing layer 2 can effectively prolong the process of surface moisture absorption and heat generation.

[0029] The cross-section of the polyester filament is an irregular structure with grooves on the surface, and the fineness specification of the polyester filament is 45D / 24F.

[0030] Both the aerogel fiber filaments and the viscose yarn have a fineness of 32S.

[0031] In the weft yarn of the moisture-absorbing and heat-generating layer 3, the blending ratio of cotton fiber to modified acrylic fiber is 15:85. The fineness of the blended yarn is 32S, and the twist is 840 twists / m. The modified acrylic fiber mainly improves the fiber's moisture absorption by increasing hydrophilic groups. In addition to the heat generated by the moisture conversion of the hydrophilic groups, which brings warmth to the human body, the high moisture absorption also keeps the skin surface dry, avoiding the damp and cold feeling caused by sweating. When modified acrylic fiber and cotton fiber are blended in the above ratio, a stronger moisture-absorbing and heat-generating function can be achieved.

[0032] The fabric has a warp density of 400 threads / 10cm and a weft density of 360 threads / 10cm.

[0033] The overall unit area mass of the fabric is 239g / m2, and the overall thickness is 1.312mm.

[0034] The modified polyester filament has a fineness specification of 75D / 72F. Due to the grafted hydrophilic groups, the modified polyester filament has good antibacterial properties. In addition, the fiber has excellent moisture absorption and quick-drying properties, creating a dry environment where bacteria cannot easily multiply.

[0035] This invention utilizes a scientific interlayer yarn configuration to form a gradient combination of moisture-wicking, moisture-storing, and moisture-absorbing heat-generating properties. At the same time, the double-layer honeycomb structure and the outer insulation layer 4 enhance the fabric's warmth to a certain extent. It also features good breathability, excellent one-way moisture-wicking performance, and a certain degree of elasticity, resulting in superior overall performance.

[0036] This invention utilizes the differential capillary effect theory to design a multi-layered fabric structure using yarns with different compositions and linear densities. This creates a capillary pressure difference between the inner and outer layers, accelerating moisture wicking and absorption. Simultaneously, when moisture is transferred from the inner layer to the outer layer, the strong capillary pressure prevents the moisture from rapidly diffusing to the surface, thus achieving a water storage function.

[0037] The honeycomb structure of this invention utilizes the alternating arrangement of long and short floats to create an uneven appearance on the fabric surface. The raised portions can form channels that can accommodate a large amount of still air, thereby enabling the absorption of moisture.

[0038] This invention utilizes irregularly shaped cross-section polyester filaments with grooved surfaces to effectively enhance moisture wicking and absorption capabilities. The grooves facilitate the formation of moisture-wicking channels within the fiber, thereby improving its wicking performance.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
