Technical Field
[0001] This invention relates to the field of functional textile composite materials technology, specifically to fleece fabric based on bamboo charcoal fiber and its preparation method. Background Technology
[0002] Fleece fabric, with its excellent warmth, lightweight texture, and economical cost, has become an important choice for outdoor sports, leisure wear, and everyday clothing. However, with the expansion of application scenarios and the improvement of consumer quality demands, traditional fleece fabrics, mainly constructed of polyester fibers, have exposed several inherent defects that are difficult to reconcile, limiting their application in high-end fields. On the one hand, polyester fibers have poor moisture absorption, resulting in weak sweat wicking. During strenuous exercise or changes in ambient temperature and humidity, sweat easily accumulates between the skin and the fabric, creating a stuffy and sticky feeling, significantly reducing dynamic comfort. On the other hand, polyester fibers are excellent insulators with high surface resistivity, leading to severe static electricity buildup in dry environments. This results in discomfort when worn and a tendency to attract dust. Finally, the fluffy and soft 3D structure of fleece easily becomes a breeding ground for bacteria and fungi, making the fabric prone to unpleasant odors, deteriorating hygiene, and potentially causing health problems.
[0003] Therefore, developing fleece fabrics with multiple functions such as moisture absorption, antistatic properties, antibacterial properties, and deodorization is of great practical significance and application value. Summary of the Invention
[0004] The purpose of this invention is to overcome the above-mentioned shortcomings of the prior art and provide a multifunctional fleece fabric based on bamboo charcoal fiber and its preparation method.
[0005] The technical solution of the present invention is as follows:
[0006] A multifunctional fleece fabric based on bamboo charcoal fiber, the preparation method of which includes the following steps:
[0007] (1) Provide polyester fleece base layer:
[0008] (2) Preparation of three-dimensional porous graphene / Mg-doped ZnO-CeO2 composite functional material: a. Graphene oxide is uniformly dispersed in deionized water; b. Zinc salt, cerium salt and magnesium salt are dissolved in deionized water at a Zn:Ce:Mg molar ratio of (70-85):(14-28):(1-5) to prepare a metal salt solution; c. Urea and hexamethylenetetramine are added to the solution, and the molar ratio of (zinc salt + cerium salt):urea:hexamethylenetetramine is 1:(1-2):(0.5-1); d. The solutions obtained in step a and step c are mixed, stirred evenly and then transferred to a hydrothermal reactor and reacted at 160-200℃ for 8-16 hours; the reaction product is centrifuged and washed and then freeze-dried to obtain a black and fluffy three-dimensional porous graphene / Mg-doped ZnO-CeO2 composite functional material.
[0009] (3) Functional treatment of bamboo charcoal fiber: The composite functional material is dispersed in the adhesive to make a functional finishing liquid, which is then applied to the bamboo charcoal fiber fabric through a padding-drying process;
[0010] (4) By laminating the polyester fleece base layer and the functionalized bamboo fiber into one piece, a bamboo fiber-based fleece fabric can be obtained.
[0011] In one specific embodiment, the adhesive is a waterborne polyurethane or acrylic resin.
[0012] In one specific embodiment, the lamination process is hot melt adhesive dot matrix lamination.
[0013] In one specific embodiment, the concentration of graphene oxide is 1.0-2.0 mg / mL.
[0014] In one specific embodiment, Mg-doped ZnO-CeO2 is a nanoflower-like structure that grows on the surface of three-dimensional graphene sheets.
[0015] In one specific embodiment, the bamboo charcoal fiber is a blended fabric of bamboo charcoal fiber and polyester, wherein the mass percentage of bamboo charcoal fiber is 60-80%.
[0016] In one specific embodiment, the mass ratio of the composite functional material to the adhesive is (6-7):1.
[0017] Compared with the prior art, the technical solution of this application can achieve the following technical effects:
[0018] (1) The three-dimensional interconnected porous structure of three-dimensional porous graphene serves as a carrier for Mg-doped ZnO-CeO2, providing a huge specific surface area. It constructs an efficient electronic conduction and heat transfer network inside the fabric, which directly endows the fabric with durable antistatic ability and can improve comfort by promoting heat diffusion.
[0019] (2) Graphene helps with physical antibacterial activity; the synergistic release of Mg, Zn, and Ce ions can efficiently interfere with bacterial enzyme systems and metabolism; under light irradiation, the Mg-doped ZnO-CeO2 with its high specific surface area and flower-like structure generates reactive oxygen species (ROS), achieving efficient photocatalytic sterilization. Mg doping introduces stress and oxygen vacancies into the ZnO-CeO2 lattice, promoting the effective separation of photogenerated electron-hole pairs, which is conducive to further generating reactive oxygen species and enhancing the photocatalytic sterilization efficiency. Through multiple mechanisms of physical antibacterial activity combined with chemical interference and photocatalytic oxidation, the composite material has a broad-spectrum and efficient killing effect on Escherichia coli, Staphylococcus aureus, etc., and is not prone to inducing bacterial resistance.
[0020] (3) This invention employs a one-step hydrothermal method, introducing urea and hexamethylenetetramine to regulate the Mg-doped ZnO-CeO2 into a flower-like structure, which is chemically bonded to the graphene framework; then, through padding and baking, it is combined with bamboo charcoal fiber fabric, allowing the functional material to deeply penetrate and anchor in the pores and surface of the bamboo charcoal fiber fabric, resulting in high bonding strength; finally, lamination is used to achieve overall structural stability. This stable structure ensures that the fabric maintains excellent durability when facing frequent friction and washing.
[0021] (4) The excellent moisture absorption and quick-drying properties of bamboo charcoal fiber fabric can quickly transfer skin sweat to the outer layer of the fabric, providing a continuous raw material for the catalytic decomposition function of composite functional materials, and realizing the dynamic and efficient performance of the function.
