Abstract
The invention belongs to the technical field of antibacterial, antiviral and mildewproof finishing liquid, and particularly relates to antibacterial, antiviral and mildewproof finishing liquid and application thereof, and antibacterial, antiviral and mildewproof cellulose fiber and a preparation method and application thereof. The antibacterial, antiviral and mildewproof finishing liquid provided by the invention comprises an antibacterial, antiviral and mildewproof agent, a penetrating agent and water; the antibacterial, antiviral and mildewproof agent comprises organic zinc; the concentration of the antibacterial and antiviral mildew preventive in the antibacterial and antiviral mildew preventive finishing liquid is 30-100 g/L; the concentration of the penetrant in the finishing liquid of the antibacterial, antiviral and mildewproof agent is 2-10 g/L. The antibacterial, antiviral and mildewproof finishing liquid provided by the invention can better enable the antibacterial, antiviral and mildewproof agent to penetrate into the cellulose fiber, and the content of the antibacterial, antiviral and mildewproof agent in the antibacterial, antiviral and mildewproof cellulose fiber is increased, so that the durability of the antibacterial, antiviral and mildewproof performance of the antibacterial, antiviral and mildewproof finishing liquid is improved.
Description
Technical Field
The invention belongs to the technical field of antibacterial, antiviral and mildewproof finishing liquid, and particularly relates to antibacterial, antiviral and mildewproof finishing liquid and application thereof, and antibacterial, antiviral and mildewproof cellulose fiber and a preparation method and application thereof.
Background
The cellulose fiber has the advantages of air permeability, skin friendliness, wearing comfort, good moisture absorption and the like, and is widely applied to the clothing and household industries, particularly as underwear, socks or bed sheets. But provides a suitable growth environment for the growth of bacteria, viruses and molds due to the high hygroscopicity of cellulose fibers and human metabolites and sloughs attached to the surface of cellulose fibers. These bacteria and viruses pose a threat to human health; meanwhile, the existence of the mould can cause the phenomena of mildew, odor emission, color change, coloring and the like of the fabric. It becomes particularly important to impart antimicrobial, antiviral and mold-resistant functionality to cellulosic fiber fabrics.
The antibacterial, antiviral and antifungal fiber is prepared by applying antibacterial agent, antifungal agent, etc. onto the surface and/or inside of fiber to release functional substance for antibacterial, antiviral and antifungal effects. Zinc is one of the essential trace elements for human life, and is called "flower of life" or "source of intelligence". Zinc has important functions on growth and development, immunologic function, material metabolism, reproductive function and the like, zinc element can accelerate the division and growth of epidermal cells, accelerate the formation of new granulation tissue of wounds and shorten the healing time of the wounds, and meanwhile zinc also has the functions of protecting skin health, resisting bacteria and viruses and preventing mildew, so that the susceptibility to infection is reduced, and the zinc has the important function of stabilizing cell membranes or organism membranes. Therefore, the zinc material is used as the antibacterial mildew preventive, and the fibers are ensured to have antibacterial, antiviral and mildew-proof properties without harming human bodies.
Chinese patent application No. 201810795002.2 discloses a preparation method of an environment-friendly antibacterial cellulose fiber, and the antibacterial agent in the patent is nano zinc oxide. The nano powder is difficult to disperse, so that the zinc oxide is not beneficial to uniformly dispersing in the cellulose fiber, and meanwhile, the patent does not protect the antibacterial agent, so that the antibacterial agent in the cellulose fiber is easy to run off, and the durability of the antibacterial performance of the cellulose fiber is influenced.
Chinese patent application No. 201811330617.4 discloses a method for preparing a durable antibacterial cellulose fiber. The patent adopts inorganic micromolecular antibacterial agents comprising zinc chloride, zinc sulfate, zinc hydroxide and zinc carbonate, and the antibacterial agent in the patent contains insoluble zinc hydroxide and zinc carbonate and is not easy to permeate into fibers in the subsequent application process to influence the antibacterial property. Most importantly, the antibacterial agent in the patent is small molecule and is easy to run off, and the problem of functional persistence is to be examined.
