With the improvement of living standard and the enhancement of health and environmental protection consciousness of people, the requirements of people on shoes are gradually expanded from softness, comfort, moisture absorption, ventilation, wind and rain prevention and the like to the aspects of mould prevention, moth prevention, sterilization, deodorization, health care, no toxicity and the like. Especially in summer and after sports, because the sweat secretion is increased sharply, microorganisms are propagated at high speed, and organic matters in the sweat are decomposed in a large amount to generate stink, so that a series of foot diseases such as foot stink, tinea pedis, dermatophytosis and the like are caused in the past, and the physical and mental health of people is directly influenced. Therefore, the antibacterial material added on the insole to relieve or inhibit a series of foot diseases such as foot odor, tinea pedis, dermatophytosis and the like becomes a hot point of research and development of people.
At present, a multilayer insole system is designed in most of schemes for solving the problem of foot odor, materials with sweat absorption and antibiosis are added in the insole system to enable the insole to prevent sweaty feet and foot odor, a medicine layer or an adsorption layer is arranged on the insole, the medicine layer is sterilized by medicines, the medicines lose efficacy along with the prolonging of the service time of the insole, chemical substances released by the medicines can cause harm to human bodies, and meanwhile, the medicines can generate medicine resistance by bacteria after long-time use; inorganic antibacterial agents have the advantages of long-acting slow release, heat resistance, safety, universality, processability and the like, and are increasingly favored by people. Therefore, more and more antibacterial clothes are coming out.
However, the inorganic antibacterial agents in the prior art are mainly nano-silver antibacterial agents, which may not be suitable for people with sensitive skin although having good antibacterial performance, and may feel stiff due to the presence of fine nanoparticles when used next to the skin and may cause allergy; meanwhile, because the compatibility between the nano-silver antibacterial agent and the fabric base material is poor, the nano-silver antibacterial agent is easy to seep from the fabric base material to cause falling off in the long-term use process, and finally the stability of the antibacterial performance of the fabric is poor.
Therefore, it is a significant work to develop a multifunctional insole which has strong antibacterial property, long-term stability, good moisture absorption and sweat releasing property and can effectively resist flame.
