Description

Technical Field

[0001] The invention relates to the technical field of textiles, in particular to a warm and moisture-permeable fabric and clothing. Background Art

[0002] At present, thermal clothing mainly relies on filling with cotton, down and other fillers. The main mechanism for achieving warmth is the above two fillers, especially the down material, which has a large number of radial down fibers. Each down fiber is composed of thousands of tiny scales stacked together, and each scale is hollow. There are many diamond nodes on each down fiber, which are full of stagnant air. It is this part of still air that greatly reduces the convective heat exchange between the cold and hot air inside and outside the clothing, thus playing a role in keeping warm.

[0003] However, the static air in down mainly exists in the diamond nodes and scales of the down fibers, and there are still gaps between different down fibers and down clusters for air circulation. In the prior art, the filling amount is often increased to further block the circulation of hot and cold air to provide a warming effect. However, down is expensive, accounting for more than half of the total cost of down jackets, so there is an urgent need to find a solution with low filling and high warmth.

[0004] Printing or coating on fabrics can improve the warmth retention of fabrics to a certain extent. However, printing or coating on the surface will block the air permeability and moisture permeability, and will also make the fabric harder, reduce wearing comfort, and the actual warmth retention experience of the wearer is not obvious. Summary of the invention

[0012] In some embodiments, the second printed pattern further includes a filling pattern, a gap is provided between the filling pattern and the second pattern block, and the second frame structure complementarily fills a projection of the gap on the base fabric layer.

[0013] In some embodiments, the frame structure is any one of a circle, a hexagon, a quadrilateral and a triangle, or a combination of two or more of the above shapes.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0036] The embodiment of the present invention provides a warm and breathable fabric, such as Figure 1 As shown, it includes a base fabric layer 1 and an inner printing layer and an outer printing layer arranged on the two side surfaces of the base fabric layer 1, the inner printing layer has a first printing pattern 2, and the outer printing layer has a second printing pattern 3, and the projections of the first printing pattern 2 and the second printing pattern 3 on the base fabric layer 1 are complementary and filled.

[0037] The thermal insulation and breathable fabric provided by the present invention increases the thermal insulation of the base fabric layer 1 by respectively arranging an inner printing layer and an outer printing layer on both sides of the base fabric layer 1; the projections of the first printing pattern 2 of the inner printing layer and the second printing pattern 3 of the outer printing layer on the base fabric layer 1 are complementary and filled, so that there is no printing pattern on the outer side of the base fabric layer 1 corresponding to the first printing pattern 2, and the inner water vapor can be effectively emitted outward from the gap of the second printing pattern 3 after passing through the base fabric layer 1 along the first printing pattern 2, thereby improving the moisture permeability of the fabric; the projections of the first printing pattern 2 and the second printing pattern 3 on the base fabric layer 1 are complementary and filled, so that the outer second printing pattern 3 can cover the gap of the inner first printing pattern 2, thereby reducing or preventing the circulation of the inner and outer air, which is conducive to forming a static air cavity 211 in the area between the inner first printing pattern 2 and the base fabric layer 1, and effectively improving the thermal insulation effect. In order to achieve the precise positioning of the first printing pattern 2 and the second printing pattern 3, it is preferred to use a double-sided synchronous printing process to print on both sides of the base fabric layer 1.

[0038] In some embodiments, the first printed pattern 2 includes a closed frame structure, and the second printed pattern 3 and the closed frame structure are complementary in projection on the base fabric layer 1 .

[0039] It can be understood that the closed frame structure has a closed geometric figure or geometric pattern, and the second printed pattern 3 is complementary to the projection of the closed frame structure on the base fabric layer 1. Therefore, the second printed pattern 3 is a plurality of discretely distributed pattern blocks, which are embedded and filled in the geometric figure, thereby facilitating the inner water vapor to be conducted along the first printed pattern 2 to the base fabric layer 1 and then dissipated to improve the moisture permeability; at the same time, the outer air is blocked by the second printed pattern 3, and the inner air is stationary in the gap of the first printed pattern 2, thereby improving the warmth retention effect.

[0040] In some embodiments, the first printed pattern 2 protrudes from the inner surface of the base fabric layer 1 and forms a plurality of air cavities 211 .

[0041] like Figure 3 The figure shows the inner side of the base fabric layer 1, and the first printed pattern 2 is set to protrude from the inner surface of the base fabric layer 1. Since the first printed pattern 2 is a closed frame structure, each closed frame structure forms an air cavity 211 with the inner surface of the base fabric layer 1. The multiple air cavities 211 are independent of each other and isolated by the frame structure. It can be understood that the protruding frame structure can block the air in the air cavity 211 from flowing along the inner surface of the base fabric layer 1. The second printed pattern 3 that is complementary to the frame structure is covered on the bottom of the air cavity 211, which can block the air in the air cavity 211 from flowing in a direction perpendicular to the base fabric layer 1. Therefore, the gas in the air cavity 211 has a relatively static effect, thereby having the effect of improving the warmth retention effect. The gap of the first printed pattern 2 is the air cavity 211 when the first printed pattern 2 is protruding from the inner surface of the base fabric layer 1.

[0042] The following is a detailed description of two different forms of frame structures.

[0043] The first form: Figure 1 and Figure 2 As shown, the frame structure is a continuous first frame structure 21, the first frame structure 21 has a plurality of closed geometric figures, the second printed pattern 3 is a plurality of discretely distributed first pattern blocks 31, and the projections of the plurality of first pattern blocks 31 and the plurality of geometric figures on the base fabric layer 1 are complementary and filled.

[0044] Taking the hexagon as an example, the continuous first frame structure 21 forms a plurality of interconnected hexagonal frames. Accordingly, the first pattern block 31 is a hexagonal block. The first pattern block 31 and the first frame structure 21 are completely complementary and filled, and the design is simple and easy to manufacture.

[0045] The second form: Figure 4 and Figure 5 As shown, the frame structure is a discrete second frame structure 22, each second frame structure 22 is a closed geometric figure, and the second printed pattern 3 includes a plurality of discretely distributed second pattern blocks 32, and the plurality of second pattern blocks 32 complementarily fill the projections of the plurality of geometric figures on the base fabric layer 1.

[0046] Taking a rectangle as an example, multiple rectangular second frame structures 22 are discretely arranged on the inner surface of the base fabric layer 1, which is conducive to giving the printed fabric better overall softness; the reason is that when the first frame structure 21 of the inner printed layer is continuously arranged, the first frame structure 21 protrudes from the inner surface of the base fabric layer 1, so it has a thicker thickness, which will affect the bending effect of the fabric. The second frame structures 22 are discretely arranged, and multiple second frame structures 22 are independent and not connected to each other, so they can maintain greater softness.

[0047] In some embodiments, the second printed pattern 3 further includes a filling pattern 33 , a gap 34 is provided between the filling pattern 33 and the second pattern block 32 , and the second frame structure 22 and the projection of the gap 34 on the base fabric layer 1 are complementary and filled.

[0048] like Figure 5The filling pattern 33 is an irregular geometric figure, which can be understood as: an outer printing layer is completely made on the outer surface of the base fabric layer 1, and a plurality of second image blocks are divided on the outer printing layer, each second image block is an independent structure, and there is a gap 34 between the circumference of the second image block and the filling pattern 33, and the size and shape of the gap 34 match the second frame structure 22, so that on the projection of the base fabric layer 1, the discretely distributed multiple second image blocks are embedded in the discretely distributed multiple second frame structures 22 one by one, and the surrounding of the first frame structure 21 is covered with the filling pattern 33 but does not overlap, so as to ensure the warmth-keeping effect.

[0049] In some embodiments, the frame structure is any one of a circle, a hexagon, a quadrilateral and a triangle, or a combination of two or more of the above shapes. The specific shape can be selected according to the actual situation, and this embodiment does not limit it. The frame structure needs to have a closed geometric shape, and the first pattern block 31 or the second pattern block 32 needs to be able to be nested in the closed combined shape to form complementary filling without overlapping.

[0050] In some embodiments, the outer printed layer is a film layer, which helps to ensure the softness of the base fabric layer 1. Since the inner printed layer is the first printed pattern 2 protruding from the inner surface of the base fabric layer 1, the outer printed layer is designed as a film layer, which helps to reduce the overall structural thickness of the warm and breathable fabric, and is easy to process into clothing.

[0051] In some embodiments, the inner printing layer is printed with a first slurry, and the outer printing layer is printed with a second slurry, and the inner printing layer is hydrophilic.

[0052] Among them, the first slurry and the second slurry are both components that are convenient for printing on the base fabric layer 1. In the embodiment of the present invention, the inner side refers to the side facing or close to the body when worn, and the outer side refers to the side away from the body when worn. By setting the inner printing layer to be hydrophilic, that is, the first printing pattern 2 is hydrophilic, the first printing pattern 2 has a moisture absorption and moisture conduction function and can be used as a moisture permeability path. The water vapor and sweat emitted by the human body are absorbed by the first printing pattern 2 and guided to the outside of the base fabric layer 1. Since the first printing pattern 2 and the second printing pattern 3 are complementary filling settings, the first printing pattern 2 has no blocking pattern on the outer surface of the base fabric layer 1, and the water vapor and sweat are directly emitted after passing through the base fabric layer 1. It can be understood that the inner printing layer is hydrophilic, which provides a moisture permeability path for the warm and breathable fabric, which is conducive to improving the moisture permeability.

[0053] In some embodiments, the first slurry is prepared by mixing a hydrophilic component, a foaming agent, a binder, and an organic solvent.

[0054] Among them, the hydrophilic component is a hydrophilic organic polymer or a hydrophilic inorganic substance. For example, the hydrophilic component is any one of polyurethane powder, polyacrylamide powder, polyacrylic acid powder, polyvinyl pyrrolidone powder, silicon dioxide powder or aluminum oxide powder, or a combination of two or more thereof. The mass content of the hydrophilic component in the first slurry is 5%-10%. During preparation, the hydrophilic component is first mixed with an organic solvent to obtain a mixture, and then 5-20 parts of the mixture, 5-10 parts of a foaming agent, 90-100 parts of an adhesive and water are mixed, and the first slurry is obtained by stirring. The organic solvent can be dimethylacetamide and / or dimethylformamide. The adhesive can be water-based polyurethane; the foaming agent can be thermoplastic expandable microsphere foaming powder, such as Expancel 461WE 40d36 product.

[0055] In some embodiments, the second slurry is formed by mixing polyimide powder, adhesive, cross-linking agent and organic solvent. The mass content of polyimide powder is 5%-10%. When preparing, the polyimide powder is first mixed with the organic solvent to obtain a mixture, and then 5-20 parts of the mixture, 5-10 parts of the cross-linking agent, 90-100 parts of the adhesive and water are mixed, and the second slurry can be obtained by stirring. The cross-linking agent is a water-based blocked aliphatic polyisocyanate cross-linking agent. It can be understood that there is no foaming agent in the second slurry, so it is conducive to preparing the second printed pattern 3 of the film structure on the outside of the base fabric layer 1.

[0056] In the thermal insulation and breathable fabric provided by the embodiment of the present invention, the first slurry contains a hydrophilic component and a foaming agent, while the second slurry does not contain a foaming agent, so that after the first slurry containing the foaming agent is printed, the first printed pattern 2 formed will expand and bulge due to foaming, thereby forming a frame structure protruding from the inner surface of the base fabric layer 1, and the closed frame structure encloses a groove space, such as Figure 3As shown, the groove space forms an air receiving cavity; at the same time, since the inner glue contains a hydrophilic component, taking the first frame structure 21 as an example, the first frame structure 21 has the function of absorbing moisture and conducting moisture, and can be used as a moisture permeable path to guide the water vapor and sweat emitted by the human body to the outer surface of the fabric, but the first frame structure 21 can block the air from flowing through the fabric covered by it. In addition, since the outer glue does not contain a foaming agent, it can be printed on the outer surface of the fabric in the form of a film-like thin layer, so the softness of the fabric after printing can be maintained to a certain extent; at the same time, since the outer first printed pattern 2 and the inner second printed pattern 3 do not overlap, that is, the position of the first frame structure 21 on the inner surface of the outer surface of the base fabric layer 1 covering the inner surface is not printed, therefore, the water vapor guided by the first frame structure 21 (the side wall of the air receiving cavity) can be effectively emitted outward, thereby constructing an effective moisture permeable path on both sides of the base fabric layer 1; on the contrary, at least a part of the outer side corresponding to the area on the inner side not covered by the first frame structure 21 is covered by the outer second printed pattern 3, so that the gas flow inside and outside the base fabric layer 1 can be reduced or blocked. When the first printed pattern 2 and the second printed pattern 3 on the inside and outside are complementary, the second printed pattern 3 on the outside can just cover the gap (air receiving cavity area) of the first printed pattern 2 on the inside, so that the air receiving cavity becomes a static air cavity 211, effectively providing a warming effect.

[0057] In the embodiment of the present invention, the specific composition of the inner and outer adhesives can refer to CN117738006A (hereinafter referred to as the background patent); the difference is that the outer adhesive of the present invention does not contain a foaming component; at the same time, the inner adhesive of the present invention uses a hydrophilic component to replace the polyimide powder, and does not include a cross-linking agent. Therefore, the second slurry on the outer side does not contain a foaming component, so after printing, a number of spaced color blocks can be formed on the outer surface of the base fabric layer 1, and the color blocks can block the flow path of the hot and cold gases through the base fabric layer 1 covered by the color blocks; and the gaps 34 between the color blocks are covered by the frame structure (the side wall of the air receiving cavity) on the inner side, so the hot and cold gases cannot flow through them either, thereby forming a blockage of the hot and cold gas flow path on the entire base fabric layer 1. But at the same time, since the first slurry on the inside contains a foaming agent and a hydrophilic component, after printing, the foaming agent component produces a large number of microbubbles and bulges, forming the side walls of the aforementioned air containing cavity, that is, a plurality of closed frame structures, and the plurality of closed frame structures enclose a large number of air cavities 211; at the same time, in the process of generating microbubbles, the hydrophilic component is dispersed at the edge of the microbubbles, so that the hole structure formed by the hose microbubbles has a hydrophilic surface, so that it can absorb and guide the water vapor inside the fabric outward, thereby improving the moisture permeability effect.

[0058] An embodiment of the present invention further provides a garment, which is at least partially made of the thermal insulation and moisture permeable fabric provided by the present invention, and the inner printing layer of the thermal insulation and moisture permeable fabric is arranged on the side facing the body.

[0059] The clothing provided by the embodiment of the present invention is at least partially made of the thermal insulation and moisture permeable fabric provided by the embodiment of the present invention, so that at least part of the clothing has a good thermal insulation and moisture permeability effect.

[0060] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
