Description

Technical Field

[0001] This invention relates to high-performance fibers and products and composite materials, and more particularly to a water-absorbing and quick-drying agent, a water-absorbing and quick-drying treatment method, water-absorbing and quick-drying fibers, and water-absorbing and quick-drying fabrics. Background Technology

[0002] Currently, there is a significant amount of research on functional knitted fabrics that wick away moisture. Manufacturers have developed many different types of products based on their specific needs and production capabilities. These products are mostly made of pure polyester or polyester-cotton blends, incorporating special weaving methods and finishing processes to give the fabrics moisture-wicking and quick-drying properties. For example, using polyester yarns with irregular cross-sections, utilizing the grooves and uneven textures on the fiber surface to enhance moisture-wicking capabilities, as seen in polyester fiber fabrics like COOLMAX. Nike's Dri-FIT fabric uses a blend of polyester and a small amount of moisture-wicking cotton, with large areas of mesh in the fibers, effectively achieving breathability and sweat absorption. Dri-FIT has a unique microfiber structure that evenly distributes sweat on the surface of the garment, allowing it to evaporate quickly; however, the fabric's structure means it is not very absorbent. Using polyester yarn as the main body of a moisture-wicking and quick-drying fabric inevitably leads to the problem of it not clinging to the skin after absorbing moisture.

[0003] Cotton fabrics have good moisture absorption and are comfortable to wear, but their molecular structure contains many hydrophilic groups (-OH). When the human body sweats heavily, water molecules combine with the -OH groups on the cotton fibers, making it difficult for moisture to leave the fibers and evaporate. This reduces the fabric's breathability and causes it to cling tightly to the body, making it less comfortable to wear. Summary of the Invention

[0037] Figure 3 This is a flowchart of a method for quick-drying and water-absorbing fabrics according to an embodiment of the present invention. Detailed Implementation

[0038] The purpose of this invention is to combine the inherent comfort and skin-friendly properties of absorbent fibers such as cotton, linen, and wood with their quick-drying and water-absorbing capabilities to solve the problem of sweating comfort in fabrics made from absorbent fibers.

[0039] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0040] The first aspect of this invention provides a water-absorbing and quick-drying agent for treating fibers or fabrics. The water-absorbing and quick-drying agent comprises: a solvent; an alcoholic substance with a volume content of 1-300 g / L; and an etherified vinyl urea resin with a volume content of 1-150 g / L.

[0041] In some embodiments of the present invention, the solvent is water; the alcohol is selected from one or more of the following materials: isopropanol, n-butanol, glycerol, polyethylene glycol, with a volume content of 80-150 g / L; the etherified vinyl urea resin is selected from one or more of the following materials: dimethylolvinyl urea resin, dimethyloldihydroxyvinyl urea resin, dihydroxyethyl sulfone, methyl etherified dimethyloldihydroxyvinyl urea resin, with a volume content of 50-100 g / L.

[0042] Preferably, the alcohol is polyethylene glycol, with a volume content of 90–110 g / L; the etherified vinyl urea resin is methyl etherified dihydroxymethyl dihydroxyvinyl urea resin ester, with a volume content of 70–90 g / L.

[0043] In some embodiments of the present invention, the fiber is selected from one or more of the following materials: cotton fiber, wood fiber, hemp fiber, bamboo fiber, rattan fiber, grass fiber, seaweed fiber, and silk fiber. Preferably, the fiber is cotton fiber.

[0044] In some embodiments of the present invention, the fabric is a fabric woven from the above-mentioned fibers or a blended yarn fabric in which the above-mentioned fibers account for more than 30%.

[0045] Regarding the fiber water-absorbing and quick-drying additive of the present invention, the following aspects need to be explained:

[0046] 1. The role of etherified vinyl urea resin in enhancing the water absorption of fibers

[0047] In the prior art, etherified vinyl urea resin is often used in the finishing stages of textiles, such as setting, wrinkle-resistant finishing, color fastness improvement finishing, and flame retardant finishing.

[0048] In this invention, the etherified vinyl urea resin primarily functions to increase the hydrophilicity of the fibers. Specifically, this is achieved by treating the fiber material to increase the surface area of ​​both the inner and outer fibers, allowing moisture to more easily penetrate the fiber interior and reach the fiber surface, thus achieving a water absorption effect. The treated fibers have a larger specific surface area, making it easier for water droplets to diffuse on the fiber surface compared to untreated fibers, resulting in a higher water evaporation rate and a faster drying effect.

[0049] 2. Its working principle differs from existing technologies that enhance the absorbency of fiber materials.

[0050] Taking the fiber water-absorbing and quick-drying additive composed of aminosiloxane and alcohol solution, which is often used in the existing technology, as an example, its principle is to use aminosiloxane to undergo condensation after hydrolysis in alcohol solution. The amino group has good hydrophilicity and can be bonded to the active groups on the fiber surface and the alcohol hydroxyl groups of polyvinyl alcohol through hydrogen bonds, thereby enhancing the hydrophilicity of the fiber.

[0051] Unlike existing technologies, this invention utilizes the principle of cross-linking reaction between etherified vinyl urea resin and polyethylene glycol: the cross-linked polyethylene glycol molecular chain has a large number of ether bonds, and the oxygen bound in the ether bonds easily forms hydrogen bonds with water molecules. Thus, the ether bonds and hydroxyl groups in the cross-linked product have good hydrophilicity, thereby greatly improving the hydrophilicity of the fiber. After the two are cross-linked, the specific surface area of ​​the original fiber is increased. Under the synergistic effect of the grafting of hydrophilic groups and the increase in specific surface area, the moisture absorption and quick-drying performance of cotton fiber can be significantly improved.

[0052] 3. The role of etherified vinyl urea resin in certain composite functional fiber treatment agents

[0053] Some composite functional fiber treatment agents can enhance the water absorption of fabrics, and these agents contain etherified vinyl urea resin. However, in these composite functional fiber treatment agents, the material that enhances water absorption is usually a silicone emulsion, etc. Specifically, the epoxy groups can self-crosslink with the terminal hydroxyl groups at high temperatures to form a hydrophilic film on the fiber surface, or they can penetrate into the fiber and undergo a crosslinking reaction with the fiber macromolecules, thereby achieving strong adsorption, increasing the hydrophilicity and water absorption rate of the fabric, and achieving a quick-drying effect. The etherified vinyl urea resin in these agents still acts as a crosslinking agent for shaping and wrinkle resistance, rather than providing the quick-drying effect described in this invention.

[0054] Based on the aforementioned fiber water-absorbing and quick-drying additives, a second aspect of the present invention provides a method for water-absorbing and quick-drying treatment of cotton fibers. Figure 1 This is a flowchart of a method for quick-drying and water-absorbing treatment of cotton fibers according to an embodiment of the present invention. Figure 1 As shown, the water-absorbing and quick-drying treatment method for cotton fibers in this embodiment includes:

[0055] The soaking step involves soaking the cotton fibers in the aforementioned cotton fiber water-absorbing and quick-drying additive.

[0056] The drying step involves drying the soaked cotton fibers.

[0057] The opening and carding step involves fully opening the cotton fibers and then combing them to obtain uniform cotton slivers.

[0058] The drawing step involves using a drawing frame to combine cotton slivers;

[0059] In the rough spinning step, a rough spinning machine is used to draw and thin the combined cotton slivers into roving;

[0060] The weaving process involves weaving quick-drying cotton yarn according to actual requirements to obtain quick-drying cotton fabric.

[0061] The following provides a detailed description of each step in the water absorption and quick-drying treatment method for cotton fibers in this embodiment.

[0062] 1. Soaking steps

[0063] In this embodiment, the cotton fibers are fully soaked in the water-absorbing and quick-drying agent for 10-60 minutes.

[0064] Those skilled in the art should understand that the soaking time of the fibers in the fiber absorbent and quick-drying agent can be selected according to the needs of the actual scenario.

[0065] 2. Drying Steps

[0066] In this embodiment, the drying step is divided into multiple stages to ensure that polyethylene glycol and etherified vinyl urea resin undergo sufficient cross-linking reaction, thereby improving the water absorption and quick-drying performance of the fiber.

[0067] Specifically, the cotton fibers are removed from the water-absorbing and quick-drying agent, pre-dried at 10-100℃ for 10-60 minutes, then dried at 100-300℃ for 10-60 minutes, rinsed with deionized water, and then dried at 30-100℃.

[0068] Those skilled in the art should understand that the drying stages, time, etc., can be adjusted and optimized according to actual needs, and the present invention is not limited to the drying procedure described above.

[0069] 3. Opening and carding steps

[0070] In this step, the cotton is fully opened and then combed to reduce short fibers and some cotton knots and impurities, effectively removing fiber fuzz. The fabric surface becomes denser, and cotton fuzz is less likely to emerge through friction, resulting in a smoother and more even surface. This step yields uniform cotton slivers.

[0071] 4. Bundling Steps

[0072] In this step, a drawing frame is used to combine the cotton slivers, reducing the unevenness of long fiber segments, eliminating curled fibers in the slivers, improving the straightness, parallelism, and separation of the fibers, and improving the quality of the cotton slivers.

[0073] 5. Wool spinning step

[0074] A roving frame is used to draw and thin the sliver into roving. A certain twist is added to the roving to increase its strength. The twisted roving is then wound onto bobbins. Subsequently, a spinning frame is used to draw, twist, and wind the semi-finished roving into fine yarn, increasing the yarn package capacity and improving the production efficiency of subsequent processes; removing defects and impurities from the yarn, and improving its quality and strength.

[0075] 6. Weaving steps

[0076] In this step, quick-drying cotton yarn is woven according to actual requirements to obtain quick-drying cotton fabric.

[0077] The moisture-wicking and quick-drying properties of the fabric prepared in this embodiment meet the evaluation requirements of GB / T21655.2-2019 Textiles for Moisture-Wicking and Quick-Drying Properties. The treated quick-drying cotton yarn has a moisture-wicking capacity comparable to that of polyester fiber; compared with the untreated cotton fiber fabric, the water-wicking and quick-drying properties are improved by two times.

[0078] Under a microscope, when cotton fibers are magnified, island-like or other shaped protrusions can be seen on the surface of the treated cotton fibers.

[0079] Analyzing from the perspective of its mechanism of action Figure 2 This is a schematic diagram comparing the water diffusion process of raw cotton fibers and treated cotton fibers. In the diagram, (a) is the raw cotton fiber, where water diffuses inward quickly; (b) is the cotton fiber after the soaking and drying steps in this embodiment. It can be seen that the treated cotton fiber has an increased specific surface area, which increases the surface area for water diffusion and improves the efficiency of sweat evaporation.

[0080] As can be seen, the preparation method of this embodiment retains the skin-friendly and soft properties of cotton fibers, thus developing a high-performance, moisture-wicking, quick-drying pure cotton fabric suitable for sportswear. This cotton fiber moisture-wicking and quick-drying fabric provides a skin-friendly feel and comfort that polyester fiber quick-drying fabrics do not have.

[0081] It should be noted that this embodiment is a preferred embodiment and includes all steps. However, in other embodiments of the present invention, only the soaking step and the drying step may be included, and the present invention can still be achieved, and is also within the protection scope of the present invention.

[0082] Similarly, this embodiment uses cotton fiber as an example for illustration. However, in other embodiments of the present invention, the fiber can also be absorbent fiber such as wood fiber, hemp fiber, bamboo fiber, rattan fiber, grass fiber, seaweed fiber, or silk fiber, and the present invention can still be achieved, and is also within the protection scope of the present invention.

[0083] Similarly, this embodiment uses fiber as an example for illustration, but the present invention is not limited thereto. Those skilled in the art should understand that the preparation method of the present invention can also be applied to fabrics woven from the above-mentioned fibers or blended yarn fabrics with the above-mentioned fiber content of 30% or more, and are also within the protection scope of the present invention.

[0084] The following describes specific examples of the water-absorbing and quick-drying treatment method for cotton fibers according to the present invention.

[0085] The present invention will be further described below with reference to embodiments. However, the present invention is not limited to these embodiments.

[0086] 1. Example 1

[0087] (1) Weigh 60g / L etherified vinyl urea resin and 80g / L polyethylene glycol into a beaker, add water at a bath ratio of 1:10, and stir with a magnetic rotor until dissolved;

[0088] (2) Soak a 10×10cm cotton fabric substrate in the prepared solution for 5 minutes, squeezing it several times during the process to ensure that the solution fully enters the pores of the fabric substrate.

[0089] (3) Take out the soaked fabric, place it in a stainless steel tray, and heat it in a 180°C oven until dry to obtain a water-absorbing and quick-drying fabric.

[0090] 2. Example 2

[0091] The substances and methods used in Example 2 are the same as those in Example 1, except that the etherified vinyl urea resin used is 100 g / L and the polyethylene glycol is 80 g / L.

[0092] 3. Example 3

[0093] The substances and methods used in Example 3 are the same as those in Example 1, except that the etherified vinyl urea resin used is 60 g / L and the polyethylene glycol is 100 g / L.

[0094] 4. Example 4

[0095] The substances and methods used in Example 4 are the same as those in Example 1, except that the etherified vinyl urea resin used is 80 g / L and the polyethylene glycol is 100 g / L.

[0096] 5. Example 5

[0097] The substances and methods used in Example 5 are the same as those in Example 1, except that the etherified vinyl urea resin used is 100 g / L and the polyethylene glycol is 100 g / L.

[0098] 6. Example 6

[0099] The substances and methods used in Example 6 are the same as those in Example 1, except that the etherified vinyl urea resin used is 60 g / L and the polyethylene glycol is 120 g / L.

[0100] 7. Example 7

[0101] The substances and methods used in Example 4 are the same as those in Example 1, except that the etherified vinyl urea resin used is 100 g / L and the polyethylene glycol is 120 g / L.

[0102] 8. Example 8

[0103] The method used in Example 8 is the same as that in Example 1. The difference in materials is that polyethylene glycol is replaced with isopropanol at a dosage of 100 g / L, and etherified vinyl urea resin is used at a dosage of 80 g / L.

[0104] 9. Example 9

[0105] The method used in Example 9 is the same as that in Example 1. The difference in materials is that the etherified vinyl urea resin used is replaced with dihydroxyethyl sulfone, and the dosage is 100 g / L. The dosage of polyethylene glycol is 100 g / L.

[0106] 10. Comparative Example 1

[0107] In Comparative Example 1, cotton fabrics were treated with 80 g / L of conventional modified aminosiloxane oligomer and 100 g / L of polyvinyl alcohol, using the same treatment method as in Example 1.

[0108] 11. Comparative Example 2

[0109] In Comparative Example 2, the cotton fabric material was not treated.

[0110] The method for determining the water absorption and quick-drying effect is to drop a fixed amount of water (e.g., 0.3 ml) onto the fabric surface and observe the moisture residue rate within 1 hour. If the moisture residue rate is below 30%, the fabric can be judged to have good water absorption and quick-drying ability.

[0111] Table 1 summarizes the water absorption and quick-drying effects of the treated fabrics in each example. The following conclusions can be drawn from the experimental results in Table 1:

[0112] 1. The fibers treated by this invention have better water absorption and quick-drying performance than those of existing technologies (i.e., modified aminosiloxane oligomers and polyvinyl alcohol);

[0113] 2. Alcohols such as polyethylene glycol and isopropanol, which are commonly used as solvents for resin-based polymers, can produce similar effects, but polyethylene glycol is more effective.

[0114] 3. Etherified vinyl urea resin and resins with hydrophilic hydroxyl groups, such as dihydroxyethyl sulfone, can produce similar effects, with etherified vinyl urea resin being the best.

[0115] 4. During the optimization process, the best results were achieved when polyethylene glycol was at 90–110 g / L and etherified vinyl urea resin was at 70–90 g / L.

[0119] 1. Impregnation step: Immerse the fabric in a water-absorbing and quick-drying agent;

[0120] Specifically, the absorbent and quick-drying agent is prepared to the required concentration and added to the tenter frame for thorough impregnation. The dosage of the absorbent and quick-drying agent is 1 to 10% of the fabric weight, preferably 3%.

[0121] 2. The water-removing step involves squeezing to remove the water-absorbing and quick-drying additives from the fabric.

[0122] Specifically, the moisture and additives on the fabric are squeezed out by a rolling mill.

[0123] 3. Drying step: Dry the fabric.

[0124] Specifically, drying is carried out at a constant temperature of 100-200℃ for 1-10 minutes. Preferably, the temperature is 140℃ and the drying time is 2-3 minutes.

[0125] Through the above steps, a well-treated absorbent and quick-drying fabric is obtained.

[0126] A fourth aspect of the present invention provides a water-absorbing and quick-drying fiber. This water-absorbing and quick-drying fiber is obtained by treating the fiber using the aforementioned water-absorbing and quick-drying treatment method.
