Description

Technical Field

[0001] This application relates to the technical field of fabrics, and particularly to fabrics with moisture absorption, heat generation, moisture conduction, quick drying, and warmth retention properties and their products. Background Art

[0002] In recent years, with the rapid development of the social economy and the significant improvement of people's living standards, consumers' demands for textiles are no longer limited to basic warmth retention and covering functions, but they pay more attention to their warmth retention, comfort, and functionality. Especially in autumn and winter, the choice of close-fitting clothing has become the focus of consumers' attention. These clothes not only need to have good warmth retention performance, but also need to have characteristics such as moisture absorption, heat generation, moisture conduction, and quick drying to meet people's needs to keep the body warm and dry in cold weather. The heat-generating and warmth-retaining fabrics in traditional technologies, through the high moisture absorption of fibers, generate moisture absorption differential heat after moisture absorption, so that the fabrics have the characteristics of moisture absorption and heat generation. However, the heat generated after heating has a great relationship with the initial moisture regain rate. If the initial moisture regain rate is large, the moisture absorption amount is large, and the heat generation amount is also large. Obviously, traditional textiles cannot meet the needs of consumers.

[0003] At present, there are already various fabrics with moisture absorption and heat generation functions on the market. These fabrics are mainly realized through two technical routes: one is to chemically treat existing fabrics by adding specific chemical substances to endow the fabrics with moisture absorption and heat generation properties; although this method can significantly improve the moisture absorption and heat generation performance of the fabrics, the added chemical components may have potential impacts on human health, and the treatment process is complex and the cost is high. The other is to use new fiber materials, such as fibers that can generate heat by themselves, to make fabrics through blending; the fabrics made by blending new fibers can achieve better moisture absorption and heat generation effects, but these new fibers are often expensive and the production process is complex, making it difficult to be widely promoted and applied on a large scale.

[0025] Term explanation:

[0026] Moisture absorption and heat generation, which is a characteristic of the fabric. It means that when the fabric absorbs the moisture (i.e., sweat) excreted by the human body, it can generate heat through chemical reactions or physical changes (such as the heat preservation effect after the fiber absorbs moisture), thereby enhancing the warmth feeling of the wearer.

[0027] Moisture conduction and quick drying refer to the fabric's ability to quickly conduct the moisture (sweat) on the skin surface to the outer layer of the fabric and evaporate it quickly to keep the skin dry and comfortable.

[0028] One-way moisture-conducting layer, which is a layer structure in the fabric. Its main function is to enable moisture (sweat) to be conducted unidirectionally and quickly from the skin side to the outer layer of the fabric, and it is not easy to reverse osmosis, so as to keep the skin-contact surface dry.

[0029] Micro fluff, tiny fluff provided on the surface of the fabric. These fluff can increase the comfort of the fabric, reduce the friction and irritation to the skin, and may also contribute to the warmth retention and moisture absorption of the fabric to a certain extent.

[0030] Heat-insulating layer, a structural layer used to improve the heat-insulating performance of the fabric, usually made of materials with good heat-insulating performance.

[0031] Hydrophobic layer, this layer is specially treated to make the fibers have waterproof functions, which can effectively prevent external moisture from penetrating into the interior of the fabric and keep the interior dry.

[0032] The water-absorbing surface layer usually has good moisture absorption performance, can quickly absorb the moisture (sweat) discharged from the skin, and conduct it away to the outer layer through the fabric structure for evaporation.

[0033] Plain knitting stitch, the basic stitch of knitted fabrics. Its characteristic is that the loops are composed of plain stitches both longitudinally and transversely, and each yarn sequentially forms loop columns in the longitudinal (warp) and transverse (weft) directions of the knitted fabric, so that the longitudinal and transverse directions of the entire knitted fabric have similar extensibility and elasticity.

[0034] Knitted covered stitch, also known as core-spun yarn stitch, is a stitch formed by wrapping an additional yarn (covered yarn) around the basic yarn on the basis of knitting a plain stitch. This stitch can enhance the elasticity and warmth retention of the fabric.

[0035] Liquid ammonia treatment, a textile finishing technology. By treating fibers with liquid ammonia, certain properties of the fibers can be improved, such as enhancing the moisture absorption, gloss, and softness of the fibers.

[0036] Elastomeric fiber yarn refers to yarns spun from fibers with elasticity or resilience, such as polyurethane or polyolefin fibers. Such yarns are prone to forming shrinking loops during the weaving process, which helps to enhance the elasticity and shaping ability of the fabric.

[0037] Linear density, also known as fineness, is a physical quantity describing the thickness of yarn. It is usually expressed by the mass of yarn per unit length (grams per kilometer) or the length of yarn per unit mass (kilometers per gram).

[0038] Specific surface area refers to the surface area of a unit mass of material, usually expressed by the total surface area per unit mass (square meters per gram). A larger specific surface area means that the material has more surface structures and stronger surface energy.

[0039] Traditional fabrics tend to have a reduced warmth retention performance in a humid environment, and are not easy to dry quickly after absorbing moisture, which affects the wearing experience. To solve this technical problem, the present application provides a fabric with moisture absorption, heat generation, moisture conduction, quick drying, and warmth retention as shown in Figure 1-2 The fabric includes a moisture-conducting and heat-generating layer 1, a hydrophobic layer 2, a water-absorbing surface layer 3, and a heat-insulating layer 4; the moisture-conducting and heat-generating layer 1, the hydrophobic layer 2, and the water-absorbing surface layer 3 are attached to each other in sequence from top to bottom; the heat-insulating layer 4 is disposed between the moisture-conducting and heat-generating layer 1, the hydrophobic layer 2, and the water-absorbing surface layer 3.

[0040] Specifically, in the present application, the moisture-conducting and heat-generating layer enhances the moisture absorption and heat generation performance of the fabric, and at the same time accelerates the speed of sweat drainage, keeping the skin-contact surface dry.

[0041] The insulation layer enhances the warmth retention of the fabric, allowing the wearer to stay warm even in cold environments; the insulation layer cotton thread is threaded between the layers, fixing the moisture-conducting and heat-generating layer and the hydrophobic layer to each other, ensuring the overall stability and durability of the fabric, while enabling the layers to work together to achieve optimal performance.

[0042] The hydrophobic layer improves the waterproof performance of the fabric and enhances the comfort and practicality of wearing.

[0043] The water-absorbent surface layer enhances the fabric's ability to absorb water, further improving the quick-drying effect.

[0044] Therefore, the above-mentioned fabric, through the cooperation of the moisture-conducting and heat-generating layer and the water-absorbing surface layer, realizes the rapid transfer and evaporation of sweat, keeping the skin-contacting surface dry; the use of the thermal insulation layer enhances the warmth-keeping effect of the fabric, which is suitable for cold environments. The design of the hydrophobic layer prevents external moisture penetration, while ensuring the discharge of internal moisture.

[0045] In some embodiments, the moisture-conducting and heat-generating layer 1 comprises a moisture-absorbing and heat-generating layer 11 and a unidirectional moisture-conducting layer 12 attached together from top to bottom. The moisture-absorbing and heat-generating layer is woven by a first yarn and a second yarn, and the unidirectional moisture-conducting layer is woven by a second yarn and a third yarn; the linear density of the third yarn is greater than that of the first yarn, and the second yarn is a yarn that can form a shrink coil.

[0046] Specifically, in the present application, the hygroscopic and heat-generating layer is woven by a first yarn and a second yarn, wherein the first yarn is a yarn spun from pure cotton fiber treated with liquid ammonia, and the fiber remains unchanged after absorbing moisture, thereby maintaining stable thermal insulation performance; the second yarn is an elastic fiber yarn of polyurethane or polyolefin, which is easy to form a contracted coil, which causes water molecules to move violently when transferring between fibers, thereby releasing heat and enhancing the hygroscopic and heat-generating capacity of the fabric.

[0047] Specifically, in the present application, the unidirectional moisture conducting layer is formed by weaving the second yarn and the third yarn, the linear density of the third yarn is greater than that of the first yarn, and the linear density is 1.5 to 2 times that of the first yarn, and has a larger specific surface area and surface energy. This design allows sweat to be quickly transferred from the moisture absorbing and heating layer to the unidirectional moisture conducting layer, and quickly diffused through its high linear density fiber structure, achieving rapid drying of the skin-contacting surface.

[0048] More specifically, the third yarn is a pure cotton fiber yarn, which has the characteristic of fiber expansion and elongation after moisture absorption. This characteristic enables the expansion of the fiber to push water molecules to move in a specific direction (i.e., away from the skin) during moisture absorption, and the linear density of the third yarn is designed to be 1.5 to 2 times the linear density of the first yarn, which makes the unidirectional moisture-conducting layer have a larger specific surface area and surface energy than the moisture-absorbing and heat-generating layer. Therefore, when sweat penetrates from the skin into the moisture-absorbing and heat-generating layer, due to the difference in surface energy and specific surface area, the sweat will quickly transfer from the moisture-absorbing and heat-generating layer to the unidirectional moisture-conducting layer, and continue to diffuse to the outer layer, thereby achieving the effect of unidirectional moisture-conducting.

[0049] In some specific embodiments, micro fleece is arranged on the moisture absorbing and heating layer 11. The height of the micro fleece is 0.1-0.2 mm. By arranging the fleece with a length of 0.1-0.2 mm on the surface of the moisture absorbing and heating layer, a micro fleece structure is formed. This structure increases the contact area between the fabric and the skin, and improves the moisture absorption and warmth retention of the fabric.

[0050] Moreover, the moisture-absorbing and heating layer is woven with yarns spun from pure cotton fibers treated with liquid ammonia and other functional yarns (such as elastic fiber yarns of polyurethane or polyolefin). These materials can generate heat after absorbing moisture, and the micro-fleece structure helps to retain and transfer this heat. When sweat is absorbed by the moisture-absorbing and heating layer and diffuses to the surface of the micro-fleece, as the water evaporates, it will take away the heat from the skin surface, thus creating a cool feeling. This evaporative heat dissipation effect combined with the micro-fleece structure further enhances the moisture absorption and heating performance of the fabric.

[0051] In some specific embodiments, the moisture-conducting and heat-generating layer adopts a knitted plated yarn structure; the hydrophobic layer adopts a knitted plain weave structure; and the water-absorbent surface layer adopts a knitted terry structure.

[0052] Specifically, the moisture-conducting and heat-generating layer can form a multi-layer fiber structure in the moisture-conducting and heat-generating layer by adopting a knitted yarn structure, thereby enhancing the moisture absorption and air permeability of the fabric. This structure helps water molecules to migrate quickly inside the fabric and further be discharged through subsequent layers (such as a unidirectional moisture-conducting layer), thereby achieving rapid drying and warmth retention, and solving the problem that traditional fabrics often have difficulty in quickly discharging moisture inside the fabric after absorbing moisture, thus affecting wearing comfort and warmth retention.

[0053] Specifically, the hydrophobic layer adopts a knitted plain weave and is combined with waterproof finishing technology, so that the hydrophobic layer has both waterproof function and can maintain the breathability and wearing comfort of the fabric, prevent external moisture from penetrating into the interior of the fabric, and at the same time maintain the breathability and softness of the fabric.

[0054] Specifically, the water-absorbent surface layer adopts a knitted terry tissue structure, combined with hydrophilic finishing technology, so that the water-absorbent surface layer has excellent water absorption performance and rapid diffusion ability, improves the water absorption capacity of the fabric surface, and accelerates sweat absorption and diffusion.

[0055] In some specific embodiments, the thermal insulation layer 4 is woven from pure cotton hollow yarns 41 .

[0056] Specifically, the hollow structure inside the pure cotton hollow yarn can effectively reduce heat conduction, thereby improving the thermal insulation performance of the fabric, allowing the wearer to stay warm even in cold environments; the pure cotton hollow yarn is lighter than solid yarn, making the entire fabric more comfortable and breathable while ensuring warmth retention. Moreover, the thermal insulation layer is fixedly connected by cotton thread inserted between the moisture-conducting and heat-generating layer, the hydrophobic layer, and the water-absorbing surface layer, which enhances the overall stability and durability of the fabric. The pure cotton hollow yarn not only plays a connecting role, but also ensures the close fit between the layers, avoiding sliding or misalignment between layers.

[0057] In addition, the pure cotton hollow yarn as the material of the thermal insulation layer has excellent thermal insulation, lightness and breathability. The pure cotton material also has good skin affinity and biocompatibility, and is suitable for direct contact with the skin.

[0058] In some specific embodiments, the hydrophobic layer and the water-absorbent surface layer are both woven from pure cotton fiber yarns.

[0059] Specifically, the moisture absorption capacity of the pure cotton fiber yarn on the water-absorbent surface is significantly improved after hydrophilic finishing, and it can quickly absorb and conduct sweat to keep the skin-contacting surface dry and comfortable.

[0060] The pure cotton fiber yarn of the hydrophobic layer has been waterproofed to effectively block the penetration of external moisture, while allowing the moisture inside the fabric to move to the water-absorbing surface layer through the capillary differential effect, achieving rapid moisture conduction.

[0061] In some embodiments, the hydrophobic layer and the water-absorbent surface layer constitute a capillary differential effect.

[0062] In traditional thermal insulation fabrics, moisture removal is often not efficient enough, which can easily lead to moisture inside the fabric, reducing the thermal insulation effect and wearing comfort. In this application, the hydrophobic layer and the water-absorbent surface layer form a capillary differential effect, which can more effectively manage and remove moisture, improving the dryness and comfort of the fabric.

[0063] Specifically, the hydrophobic layer and the water-absorbent surface layer constitute a capillary differential effect, the formation of which is mainly based on the differences and synergy between the two in material, structure and function.

[0064] 1. Material difference: The hydrophobic layer is made of pure cotton fiber yarn, and the fibers are waterproofed, endowing it with waterproof function. This means that the hydrophobic layer has a certain repulsive effect on water molecules and is not easily penetrated by water.

[0065] The water-absorbing surface layer also uses pure cotton fiber yarn, but the fibers are hydrophilized to enhance its moisture absorption capacity. This enables the water-absorbing surface layer to quickly absorb and retain moisture.

[0066] 2. Structural difference: The hydrophobic layer adopts a knitted plain weave structure, which is relatively tight and helps prevent the penetration of water molecules. The water-absorbing surface layer adopts a knitted terry structure, and the terry structure increases the contact area between the fibers and the air, improving the moisture absorption efficiency and facilitating the diffusion of moisture.

[0067] 3. Functional synergy: When the fabric comes into contact with moisture (such as sweat), due to its good hydrophilicity and moisture absorption capacity, the water-absorbing surface layer will first absorb and retain this moisture. As the moisture accumulates, due to the repulsive effect of the hydrophobic layer on moisture, a moisture concentration gradient is formed from the water-absorbing surface layer to the hydrophobic layer direction. This gradient drives the movement of water molecules between the two layers.

[0068] Due to the differences in material and structure between the water-absorbing surface layer and the hydrophobic layer, the moisture movement speed under capillary action between the two layers is different, thus forming a capillary differential effect. This effect enables moisture to move faster from the water-absorbing surface layer to the hydrophobic layer direction and is finally discharged or evaporated.

[0069] When the clothing made of the fabric described in this application is worn, the moisture absorption and heat generation layer inside it can quickly absorb the sweat discharged by the human body and transfer the sweat to the outer layer quickly through the one-way moisture conduction layer, keeping the skin-contact surface dry. At the same time, the heat preservation layer can provide good heat preservation effect, and the hydrophobic layer and the water-absorbing surface layer respectively play the roles of waterproofing and quickly absorbing external moisture.

[0070] At the same time, this application provides products, including the fabric described above. Specific products include:

[0071] Intimate clothing: Such as underwear, long johns, thermal underwear, etc. These clothes need to have good heat preservation performance, and at the same time require moisture absorption, heat generation, and fast moisture conduction and drying to meet people's needs for keeping the body warm and dry in cold weather.

[0072] Sports goods: It is easy to sweat during sports, so sports goods (such as sports T-shirts, sports pants, sports jackets, etc.) made of this fabric can quickly absorb and discharge sweat, keep the body dry, and improve sports comfort.

[0073] Outdoor clothing: During outdoor activities, the weather is changeable, and there are high requirements for the warmth retention, breathability, and quick-drying properties of clothing. Outdoor clothing made of this fabric (such as windbreakers, fleece jackets, etc.) can well meet these needs.

[0074] Household items: Such as bedding (duvet covers, sheets, pillowcases, etc.) and home clothes. These products also need to have good warmth retention and comfort. Using the moisture-absorbing, heat-generating, moisture-conducting, and quick-drying warmth retention fabric can enhance the user's home experience.

[0075] The above is a specific description of the preferred embodiment of this application. However, the creation of this application is not limited to the described embodiment. Those skilled in the art can also make various equivalent deformations or substitutions without departing from the spirit of this application. These equivalent deformations or substitutions are all included within the scope defined by the claims of this application.
