Description

Water-absorbent deformable fabric

This invention relates to the field of fabric manufacturing technology, specifically to a water-absorbent, deformable fabric. This fabric absorbs water, deforming to create convex and concave shapes, thereby increasing air circulation between human skin and the fabric and accelerating drying speed. Furthermore, the use of water-based polyurethane significantly reduces environmental pollution during the manufacturing process.

Since the Industrial Revolution, people's demands for fabrics have become increasingly demanding, whether in terms of material quality, tailoring, or functionality. The development of various functional textiles has also been increasingly sophisticated. For example, fabrics with breathability, perspiration wicking, heat dissipation, flame retardancy, and thermal insulation are all worthy of investment. With the increasing emphasis on outdoor activities and sports, sportswear is not only required to wick away moisture and provide a quick-drying feel. However, during sports or in warmer climates, people sweat profusely. This perspiration can cause fabric to stick to the skin, further hindering the fabric's perspiration and breathability, resulting in an uncomfortable stickiness. To improve the adhesion of fabric to human skin, Some products already exist on the market, such as bicomponent fibers made of polyester and polyamide. These fibers utilize the different shrinkage rates of the two components. After absorbing moisture, the yarns expand and stretch to varying degrees, causing them to bend and increase the spaces between them. This increases the fabric's breathability and releases trapped air. When dry, the yarns contract, reducing breathability and improving thermal comfort during exercise. Alternatively, unique fiber modification and composite spinning technologies are employed to create composite yarns of highly hydrophilic modified diacetate fibers and less hydrophilic triacetate fibers. When drying, the modified diacetate fiber evaporates and contracts, creating gaps in length between the two acetate fibers and forming a spiral curl. When wet, the modified diacetate fiber absorbs moisture, swells, and stretches, increasing the fabric's breathability.

However, the production processes for both of these fabrics are relatively complex, limiting the types of fabrics that can be produced. Furthermore, the high cost makes them impractical and uneconomical. Furthermore, in the textile industry, most companies use solvent-based polyurethanes, which produce hazardous substances (VOCs) during production, potentially impacting human health and even the environment. Some European countries have already enacted legislation prohibiting the indoor use of solvent-based raw materials. To meet the industry's sustainable development goals, inventors are actively developing these environmentally friendly water-based polyurethanes to stay ahead of market trends.

In other words, developing a fabric that absorbs moisture and dries quickly, allowing the skin's surface to ventilate and return to a dry state, while also ensuring an environmentally friendly and stable manufacturing process and low toxicity to avoid harm to the human body, is a highly anticipated goal in the industry and is the focus of this invention.

In light of these shortcomings and needs, the inventors, drawing on their years of experience in related technologies and product design and manufacturing, have conducted research and innovation to address these issues, actively seeking solutions. After continuous research and trial production, they have successfully developed a water-absorbing, deformable fabric that overcomes the shortcomings of existing fabrics, achieving the goals of unlimited fabric variety, a simpler manufacturing process, and the use of environmentally friendly raw materials.

Therefore, the main purpose of this invention is to provide a water-absorbing and deformable fabric, which can deform its surface to form convex and concave shapes after absorbing water, thereby increasing air circulation between human skin and the fabric, thereby reducing the stickiness between the fabric and human skin.

Another primary objective of the present invention is to provide a water-absorbing, deformable fabric that can absorb moisture while enhancing its quick-drying properties, restoring the skin's surface to a dry state.

Furthermore, another primary objective of the present invention is to provide a water-absorbent, deformable fabric. The use of water-based polyurethane not only enhances the softness of the hand, but also improves overall wearing comfort.

Another primary objective of this invention is to provide a water-absorbent, deformable fabric that utilizes a more environmentally friendly water-based polyurethane in its manufacturing process. This avoids the environmental pollution, strong odor, and flammability and explosiveness often associated with conventional solvent-based polyurethanes. This reduces the need for specialized explosion-proof and ventilation equipment, further enhancing operational safety while making the production process more environmentally friendly and stable, significantly reducing environmental pollution during production.

Based on this, the present invention primarily achieves the aforementioned objectives and effects through the following technical means: a deformable agent layer is applied to at least one of the two surfaces of a textile fabric. The deformable agent layer is composed of 25% to 35% by weight of a polyurethane resin, 25% to 35% by weight of a water-based polyurethane mixture, 10% to 20% by weight of water, and 10% to 30% by weight of a water-based adhesive.

Thus, the water-absorbing deformable fabric of the present invention is formed by coating the deformable agent layer on the fabric, wherein the deformable agent layer is composed of polyurethane resin, water-based polyurethane mixture, water and water-based adhesive, so that the water-absorbing deformable fabric can increase the moisture absorption effect and at the same time increase the drying speed. After absorbing water, it generates a concave and convex three-dimensional effect corresponding to the pattern, so that the fabric will not stick tightly. On the body, this allows the skin to remain relatively dry while allowing air to circulate through the three-dimensional space, enhancing the wearing experience during exercise and providing a more comfortable wearing experience. It also further improves the softness and comfort of the hand and effectively reduces environmental pollution during production, thereby enhancing environmental friendliness, significantly expanding its application and practicality, and effectively increasing its economic benefits.

The present invention further achieves the aforementioned objectives and effects by utilizing the following technical means; these include:

Preferably, the deformation agent layer is applied to the surface of the fabric using a gravure printing machine, a rotary screen machine, or a flatbed printing machine.

Preferably, the water-based adhesive of the deformable agent layer can be selected from water-based polyurethane (PU) adhesives.

Preferably, the deformable agent layer is applied to at least one of the two surfaces of the fabric.

Preferably, the deformable agent layer can be applied to the surface of the fabric in the form of at least one pattern, either full-width or partial.

Furthermore, the present invention can further utilize the following technical means to specifically achieve the aforementioned purpose and efficacy. According to the different desired effects and functions, a surface treatment agent layer is coated on at least one of the two sides of a fabric surface, and a deformation agent layer is coated on at least one of the two sides of the fabric surface or on the surface of the surface treatment agent layers, wherein the surface treatment agent layer is composed of 30% to 40% of the total weight. The material is composed of polysiloxane, 30% to 40% polysilazane, 10% to 20% water, and 10% to 20% water-based adhesive. The deformable agent layer is composed of 25% to 35% polyurethane resin, 25% to 35% water-based polyurethane mixture, 10% to 20% water, and 10% to 30% water-based adhesive.

Thus, the water-absorbing deformable fabric of the present invention is formed by coating the deformable agent layer and the surface treatment agent layer on the fabric, wherein the deformable agent layer is composed of polyurethane resin, water-based polyurethane mixture, water and water-based adhesive, and the surface treatment agent layer is composed of polysiloxane, polysilazane, water and water-based adhesive, and with the surface treatment agent, the deformable agent layer is composed of polysiloxane, polysilazane, water and water-based adhesive. In addition to the aforementioned benefits of increased moisture absorption and faster drying, the surface treatment layer further enhances these benefits. It also adds additional properties: the surface treatment softens and smoothes the hairiness of the fabric, improving its pilling resistance. These added features enhance the overall wearing comfort of the fabric.

This invention is a water-absorbing, deformable fabric. The following describes the technical aspects of this invention using a specific embodiment. This disclosure will allow those familiar with the art to easily understand the advantages and benefits of this invention. However, this invention can also be implemented or applied through other different embodiments.

The water-absorbent deformable fabric of the present invention is shown in FIG1 and FIG2. The water-absorbent deformable fabric is a fabric (10) on which a deformable agent layer (20) is coated on at least one of the two side surfaces. The deformable agent layer (20) is composed of 25% to 35% of polyurethane resin, 25% to 35% of water-based polyurethane mixture, 10% to 20% of water and 10% to 30% of water-based adhesive. The water-based adhesive can be selected from water-based polyurethane (PU) adhesives, which can reduce environmental pollution. In addition, the water-based polyurethane adhesive can also maintain the softness of the fabric (10) and will not cause the fabric (10) to be too hard like solvent-based polyurethane, effectively improving the overall wearing comfort of the fabric (10) after it is made into clothing. In addition, the deformable agent layer (20) can be a full-width or partial pattern. , is coated on at least one of the two side surfaces of the textile fabric (10) according to different needs and purposes, and the pattern of the deformable agent layer (20) can be selected from any one of dots [such as (A) in FIG5], lines, trademarks, cartoons, flowers [such as (B) in FIG5], text, numbers, geometry, hollow [such as (C) in FIG5] or solid or a combination thereof, to form a water-absorbing deformable fabric, so that the water-absorbing deformable fabric can utilize the pattern coated on the surface of the textile fabric (10) The deformable agent layer (20) increases the moisture absorption effect and improves the drying speed. After absorbing water, a concave and convex three-dimensional effect corresponding to the pattern is generated (as shown in Figures 3 and 4). The three-dimensional space generated by the deformable agent layer (20) prevents the fabric (10) from sticking to the body, allowing the human skin to be relatively dry. At the same time, air can flow through the three-dimensional space, enhancing the wearing experience during exercise and providing a more comfortable wearing experience.

According to some embodiments, the water-absorbing deformable fabric is first coated with a surface treatment agent layer (30) on at least one of the two side surfaces of the fabric (10), and the deformation agent layer (20) is fully or partially coated on at least one of the two side surfaces of the fabric (10) or the surface treatment agent layers (30). 0) surface, wherein the surface treatment agent layer (30) is composed of 30% to 40% of polysiloxane, 30% to 40% of polysilazane, 10% to 20% of water and 10% to 20% of water-based adhesive, and the water-based adhesive can be selected from water-based polyurethane (PU) adhesive, which can reduce pollution to the environment and can also maintain the softness of the fabric (10). Furthermore, the surface treatment agent layer (30) can be coated on at least one of the two side surfaces of the fabric (10) with a full-width or partial pattern, and the surface The texture pattern of the treatment agent layer (30) can be selected from any one of a trademark, cartoon, text, number, geometry, line, dot, hollow or solid or a combination thereof, and the deformable agent layer (20) coated on the surface of the surface treatment agent layer (30) can be a pattern corresponding to or a part of the surface treatment agent layer (30).

This creates a water-absorbing, deformable fabric structure that creates a three-dimensional concave-convex shape when exposed to water and absorbs moisture quickly while drying.

The method of coating the surface treatment agent layer (30) and the deformation agent layer (20) on the fabric (10) of the water-absorbent deformable fabric of the present invention can be performed using at least a gravure machine, a rotary screen machine or a flatbed machine.

The water-absorbing and deformable fabric of the present invention is composed as described above. When used, as shown in FIG3 and FIG4, when sweating occurs, the surface treatment agent layer (30) and the deformable agent layer (20) can be used to absorb sweat quickly, so that the water-absorbing and deformable fabric will generate a three-dimensional space similar to a concave and convex shape due to the wet state, so that air can be absorbed in the three-dimensional space. By moving back and forth occasionally, the absorbent and deformable fabric will not cling to the body, allowing the skin to return to a dry state without any stickiness or discomfort. It also has a quick-drying function, preventing the absorbent and deformable fabric from maintaining a high humidity level. This accelerates drying and allows the skin to remain relatively dry, significantly enhancing the wearing experience during exercise and providing a more comfortable wearing experience.

Experimental results show that the water-absorbing and deformable fabric of this invention not only significantly enhances its hydrophilic properties, but also demonstrates that after 30 minutes, the vertical core height of the unprocessed fabric is 0.8 cm, while the processed water-absorbing and deformable fabric has a vertical core height of 8.2 cm. Furthermore, in an evaporation test, the fabric was placed at room temperature to determine its evaporation rate in a normal environment. After 30 minutes, the evaporation rate of the unprocessed fabric was 6%, while the evaporation rate of the processed water-absorbing and deformable fabric was 18%. Furthermore, in drying speed tests, using the AATCC 201 fabric drying speed test method, fabric is placed on a 37°C heating plate to simulate the surface temperature of human skin. The water drying rate of the fabric upon contact with the fabric is 1.4 times faster than that of conventional fabric. Furthermore, the fabric's 3D effect after absorbing water increases by 200% compared to conventional fabrics.

At the same time, the deformable agent layer (20) and/or the surface treatment agent layer (30) of the water-absorbent deformable fabric is based on a water-based polyurethane adhesive. Unlike solvent-based polyurethane, organic solvents will not be volatilized into the air during the production process, and some toxic substances will cause harm to human health and the impact on the ecological environment is difficult to estimate. Therefore, the water-absorbent deformable fabric of the present invention not only reduces pollution to the environment, but also increases the softness of the hand of the water-absorbent deformable fabric, further improving the overall wearing comfort.

From the above composition and description, it can be known that the water-absorbent deformable fabric of the present invention is formed by coating the deformable agent layer (20) and the surface treatment agent layer (30) on the fabric surface (10), wherein the deformable agent layer (20) is composed of polyurethane resin, water-based polyurethane mixture, water and water-based adhesive, and the surface treatment agent layer (30) is composed of polysiloxane, polysilazane, water and water-based adhesive, so that the water-absorbent deformable fabric is formed by coating the deformable agent layer (20) and the surface treatment agent layer (30) on the fabric surface (10), wherein the deformable agent layer (20) is composed of polyurethane resin, water-based polyurethane mixture, water and water-based adhesive, and the surface treatment agent layer (30) is composed of polysiloxane, polysilazane, water and water-based adhesive, so that the water-absorbent deformable fabric is formed by coating the deformable agent layer (20) and the surface treatment agent layer (30) The water-deformable fabric can utilize the deformable agent layer (20) and the surface treatment agent layer (30) coated on the surface of the fabric (10) to increase the moisture absorption effect and at the same time increase the drying speed. After absorbing water, a concave-convex three-dimensional effect corresponding to the pattern is generated. The three-dimensional space generated by the deformable agent layer (20) prevents the fabric (10) from being tightly attached to the body, allowing the human skin to be in a relatively dry state.

At the same time, the design of the surface treatment agent layer (30) has the effects of increasing moisture absorption and drying speed mentioned above. In addition, the above functions are further enhanced by the effect of the surface treatment agent. It also adds additional characteristics. The surface treatment agent makes the hairiness on the surface of the fabric softer and smoother, and the anti-pilling ability is improved. These additional functions make the overall wearing experience more comfortable when wearing the fabric, while allowing air to pass through the three-dimensional space, increasing the wearing experience during exercise, providing a more comfortable wearing feeling, and further improving the softness of the hand feel and the wearing comfort.

In addition, the deformable agent layer (20) uses a more environmentally friendly water-based polyurethane mixture in the processing process, which does not easily cause environmental pollution, strong odor, flammability and explosion problems in the existing solvent-based polyurethane during the process. It can reduce the need for special explosion-proof and ventilation equipment in the process. In addition to reducing equipment and process costs, it further enhances operational safety and makes the production process more environmentally friendly and stable.

The above embodiments are merely preferred embodiments of the present invention and should not be used to limit the scope of protection of the present invention. Any changes or modifications that are insignificant to the main design concept and spirit of the present invention, provided that the technical problems they solve are consistent with those of the present invention, shall be included in the scope of protection of the present invention.
