Abstract
The invention relates to the field of fabric finishing agents, in particular to a cotton-linen antibacterial finishing agent. The formula of the cotton-flax antibacterial finishing agent comprises the following components in parts by weight: 30-40 parts of methyl methacrylate, 10-15 parts of nano silver-copper loaded POSS base resin, 80-100 parts of water, 0.05-0.2 part of initiator, 0.5-2 parts of emulsifier and 0.5-2 parts of hydroxyl silicone oil. The invention solves the problems that the effective components in the antibacterial finishing agent in the prior art are easy to fall off in the daily washing process to cause failure, the antibacterial components are single, and the sterilizing capability of the antibacterial finishing agent cannot be further improved, and has the advantages that (1) the good sterilizing effect is achieved by compounding the nano silver and the nano copper particles; (2) the nano silver and the nano copper ions can be effectively fixed, so that the nano silver and the nano copper ions cannot fall off along with the external acting force, and a good sterilization effect is always achieved; (3) the preparation method disclosed by the invention is simple, and meanwhile, the cost is saved.
Description
Technical Field
The invention relates to the field of fabric finishing agents, in particular to a cotton-linen antibacterial finishing agent.
Background
With the improvement of living standard, people pay more and more attention to the quality of life, and hope to obtain comfortable clothes and a sanitary and healthy living environment. The requirements for various textiles are higher and higher, and particularly the concept of 'green' such as safety, comfort, health, sanitation, cleanness and the like is formed, so that the antibacterial, mildew-proof and odor-resistant after-finishing processing of the textiles is more emphasized by people.
In life, people inevitably come into contact with various microorganisms such as bacteria and fungi, and the microorganisms can rapidly propagate under proper external conditions and spread diseases by means of contact and the like, so that the physical health and normal work, study and life of people are influenced. The fiber belongs to a porous material, and a multilayer body with countless gaps is formed after the fiber is overlapped and woven, so that the fabric can easily absorb bacteria. The antibacterial finishing is to make the fabric have the function of inhibiting the growth of bacteria, maintain the sanitary living environment of the clothes and ensure the health of human body.
In the last 60 th century, people mostly adopt organic antibacterial agents to produce antibacterial textiles; with the successful development of inorganic antibacterial agents in 1984, antibacterial finishing is rapidly developed, so that the antibacterial agents are not only used for fibers and textiles, but also used for products such as plastics, building materials and the like.
At present, the research of Japan is the most active in the aspect of antibiosis and deodorization, the technology is advanced, and the products are expanded to the fields of sportswear, carpets, medical supplies and the like. In recent years, the focus of chinese antibacterial research has shifted from protecting textiles from bacterial attack to protecting the environment and the user from bacterial attack.
In the 21 st century, with the advent of the aging society, the number of bedridden people and home patients who are nursing at home has increased, and the demand for nursing articles for the elderly to prevent bedsores has also increased. Since the concept of production-oriented society is changed to life-oriented concept, it will be an important subject in the future to develop and research products that are beneficial to human health and global environment, and therefore antibacterial finishing is increasingly receiving attention from people.
The nano zinc oxide and nano silver-loaded inorganic antibacterial agent is a green antibacterial agent which is actively researched and applied at present. When the size of zinc oxide reaches the nanometer order, compared with common zinc oxide, the zinc oxide exhibits many excellent and special properties, such as non-toxicity and non-migration. Due to the quantum size effect and the extremely large specific surface area, the antibacterial finishing agent has the advantages of small dosage, high efficiency and the like during antibacterial finishing, and has positive significance for developing and producing green and environment-friendly fabrics.
Many metal ions have antibacterial properties, and some of the metal ions have been tested for antibacterial ability by the japanese Koyasu-yangtang-zheng et al, and the results are as follows: in practice, Ag, Co, Ni, Al, Zn, Fe, Mn, Sn, Ba, Ca and the like, and the commonly used metal ions are mainly silver, copper and zinc ions.
