Description

Technical Field

[0001] This invention belongs to the field of functional fabric technology, specifically relating to an antibacterial cooling fabric and its production process. Background Technology

[0002] As people's living standards improve, their demands for the comfort and functionality of textiles are increasing. In the hot summer, the demand for coolness in fabrics is even higher. Fibers with cooling properties have gradually become a research hotspot in the clothing industry. Common cool-feeling fabrics are made of cool-feeling fibers, which improve the heat dissipation speed by increasing the thermal conductivity of the fibers, thus making the wearer feel cool. However, their moisture absorption is poor, and they cannot quickly wick away sweat after the body sweats, which can easily create a sticky feeling between the body and the fabric and easily breed bacteria. At present, in order to improve the problem of poor moisture wicking ability of cool-feeling fabrics, Chinese patents CN114164547A and CN110938934A disclose a cool-feeling fabric, which is obtained by blending dried fibers with fibers with good moisture absorption. However, after adding fibers with high moisture absorption and low thermal conductivity, the cooling effect of the fabric is reduced. Therefore, the synergistic improvement of cooling, antibacterial and moisture wicking abilities is a technical problem that needs to be solved. Summary of the Invention

[0003] In order to solve the technical problems mentioned in the background art, the present invention provides an antibacterial cooling fabric and its production process.

[0004] The objective of this invention can be achieved through the following technical solutions:

[0005] An antibacterial and cooling fabric comprises a skin-friendly layer, a connecting layer, and a functional layer from the inside out. The skin-friendly layer is made of bamboo fiber fabric, the connecting layer is made of moisture-wicking fabric, and the functional layer is made of cooling fabric.

[0006] The production process of this antibacterial and cooling fabric is as follows:

[0007] Bamboo fiber fabric, first adhesive layer, moisture-wicking fabric, second adhesive layer, and cooling fabric are placed in sequence and then hot-pressed together in a hot press to obtain antibacterial and cooling fabric.

[0008] The hot-pressing temperature is 115-120℃, and both the first and second adhesive layers are 8μm polyurethane hot melt adhesive films.

[0009] Among them, bamboo fiber fabric is obtained by twisting, spinning and weaving bamboo fiber; moisture-wicking fabric is obtained by twisting, spinning and weaving moisture-wicking fiber; and cooling fabric is obtained by twisting, spinning and weaving cooling fiber.

[0010] Furthermore, the cooling fibers are made through the following steps:

[0011] Step S11: Add graphene oxide to distilled water, add sodium hydroxide to adjust the pH to 11, sonicate at 60℃ for 0.5h, then add 0.2mol / L zinc sulfate solution, stir for 10min, then add 4mol / L sodium hydroxide solution, keep warm and stir for 1-1.5h, after the reaction is complete, filter, wash the filter cake several times with deionized water and place it in a 130℃ oven for 2-3h to obtain doped GO. The ratio of graphene oxide, distilled water, zinc sulfate solution and sodium hydroxide solution is 0.3-0.5g:90-100mL:25mL:25mL.

[0012] Step S12: Add the doped GO to a three-necked flask, add anhydrous ethanol and adjust the pH to 3-6 with formic acid, sonicate for 1 hour, stir at 65°C for 1 hour, add an ethanol solution of KH-570 and stir for 3-4 hours, centrifuge, wash and dry to obtain modified GO, the amount of KH-570 used is 1.5% of the mass of the doped GO;

[0013] Step S13: Mix ultra-high molecular weight polyethylene, modified GO, decahydronaphthalene and antioxidant evenly, transfer to a twin-screw extruder for co-extrusion to obtain a spinning solution, feed the spinning solution into a filter, and extrude it through a spinneret to obtain nascent fibers. After extraction, drying and stretching, cool-feeling fibers are obtained. The mass ratio of ultra-high molecular weight polyethylene, modified GO, antioxidant and decahydronaphthalene is 8-10:1-2:0.05-0.07:100.

[0014] Further, in step S13, the twin-screw extruder temperature is 250-270℃, the screw speed is 8 r / min, xylene is used as the extraction solvent for nascent fibers, the extraction temperature is room temperature, the liquor ratio of nascent fibers to xylene is 1:15, the extraction time is 5 min, and it is repeated 3 times. After extraction, it is dried in a fume hood at room temperature, the draw ratio is 10-20 times, the draw temperature is 120-130℃, and the weight-average molecular weight of ultra-high molecular weight polyethylene is 2×10⁻⁶. 6 -5×10 6 .

[0015] Cooling fibers are obtained by using ultra-high molecular weight polyethylene (UHMWPE) with high thermal conductivity as raw material and adding modified GO cooling powder with even higher thermal conductivity. The modified GO cooling powder is doped GO treated with coupling agent KH-570, which has good dispersion in the matrix. The doped GO is nano zinc oxide doped with graphene oxide, which overcomes the shortcomings of single fillers and plays a synergistic role in the matrix to form a thermally conductive network. It not only has the antibacterial and ultraviolet absorption effects of zinc oxide, but also the antibacterial and ultraviolet shielding effects of graphene oxide, and combines the high thermal conductivity of both. Therefore, the prepared cooling fibers can not only effectively dissipate heat and provide a cooling experience, but also reduce ultraviolet radiation and enhance the cooling sensation while being antibacterial.

[0016] Furthermore, the moisture-wicking fibers are manufactured through the following steps:

[0017] Add the quaternary ammonium salt antibacterial agent to DMF, stir evenly, then add dibutyltin dilaurate, stir evenly again to obtain the finishing solution. Immerse the pretreated cross-shaped hollow polyester fiber in the finishing solution, heat it in an 80℃ water bath for 30 minutes, then remove it and bake it in an oven at 120-130℃ for 2-3 minutes. Remove it again, wash it with water several times, and air dry it to obtain moisture-wicking fiber. The ratio of quaternary ammonium salt antibacterial agent, DMF and dibutyltin dilaurate is 38-40g:1000mL:0.5-1mL, and the ratio of pretreated cross-shaped hollow polyester fiber to finishing solution is 1-2g:10mL.

[0018] First, the cross-shaped hollow polyester fibers are subjected to plasma treatment to enrich their surface with oxygen-containing groups, thereby increasing their surface activity. Then, under the catalysis of dibutyltin dilaurate, the terminal isocyanate groups of the quaternary ammonium salt antibacterial agent react with the hydroxyl groups on the surface of the pretreated cross-shaped hollow polyester fibers, so that the quaternary ammonium salt antibacterial agent is firmly bound to the fiber surface, improving the antibacterial properties of the fiber while also improving its moisture absorption properties.

[0019] The pretreated cross-shaped hollow polyester fibers are obtained by plasma treatment process, with specific process parameters as follows: treatment power 100W, treatment gas oxygen, and treatment time 1.5min.

[0020] The quaternary ammonium salt antibacterial agent is prepared by the following steps:

[0021] 1,3-Dichloroisopropanol and dodecyl dimethyl tertiary amine were placed in a round-bottom flask, and anhydrous ethanol was added. The mixture was stirred at 50°C for 18-22 h. After the reaction was complete, the solvent was removed by rotary evaporation. The rotary evaporation product was washed repeatedly with anhydrous diethyl ether, filtered, and dried at 40°C to obtain an intermediate product. The intermediate product was added to dichloromethane, and after stirring, isophorone diisocyanate and dibutyltin dilaurate were added. The mixture was magnetically stirred at 40°C for 10-12 h. The solvent was removed by rotary evaporation, and the product was washed repeatedly with petroleum ether, filtered, and dried to obtain a quaternary ammonium salt antibacterial agent. The molar ratio of 1,3-dichloroisopropanol, dodecyl dimethyl tertiary amine, anhydrous ethanol, dichloromethane, isophorone diisocyanate, and dibutyltin dilaurate was 1.3 g: 4.2 g: 80-100 mL: 100 mL: 2.22 g: 0.15 mL.

[0022] The beneficial effects of this invention are:

[0023] This invention employs a multi-layer composite process to prepare an antibacterial and cooling fabric. Without reducing the fabric's cooling sensation, it achieves excellent moisture-wicking properties through its multi-layer structure. The top layers consist of bamboo fiber (hydrophilic) and cooling fabric (hydrophobic), with a modified cross-shaped hollow polyester fiber (with moisture-wicking properties) as the middle layer. Through capillary action, channels for moisture migration are created, giving the fabric excellent wicking properties and a wetting gradient effect. This synergistically enhances the fabric's antibacterial, moisture-wicking, and cooling properties. The antibacterial performance is attributed to three factors: the natural antibacterial properties of bamboo fiber, the quaternary ammonium salt antibacterial properties of the moisture-wicking fabric, and the cooling effect. The fabric exhibits antibacterial properties from nano-zinc oxide and graphene oxide. Bamboo fiber, as the skin-friendly layer, not only possesses antibacterial properties but also exhibits high moisture absorption, making it gentle on the skin. The moisture-wicking layer, acting as a connecting layer, enhances the antibacterial effect while simultaneously transporting moisture to the cooling layer, thus ensuring a dry and sterile interface between the skin and the fabric. The functional layer not only has excellent heat dissipation capabilities and shields against infrared, visible, and ultraviolet light but also serves as a barrier layer, reducing bacterial invasion. In summary, the fabric prepared by this invention possesses antibacterial, moisture-wicking, and cooling properties, making it highly valuable for widespread application. Detailed Implementation
