Determination of the optimal formulation and coating parameters of bee product on textile supstrate

According to the World Health Organization, it is common knowledge that bacterial resistance to antibiotics is one of the major threats to global health. Infections caused by resistant bacteria affect the entire health system where infection with a resistant strain can happen to anyone. Things get more difficult if the wounds heal slowly and require specific medical care. Medical dressings are used to treat such wounds, where the textile plays an important role as a carrier of drugs. The emphasis is on finding new ways of treatment, the application of drugs to textiles, where nature is an inexhaustible source of ideas, especially bee products. Royal jelly and propolis are one of the bee products that have many medicinal properties. Propolis consists of resin, wax and essential oils, vitamins and minerals, but the emphasis is on flavonoids. Flavonoids are found in plant resin and become pharmacologically active by the enzymatic modification that bees make when making propolis. They, in combination with other components of propolis, carry most of the positive effects that propolis has. Propolis has the properties of antibiotics, anaesthetics, antioxidants and antiseptics, so it works great against most viruses, but also fungi and parasites. This paper was focused on the research of the possibilities provided by the application of inorganic-organic substances with royal jelly and propolis, but also the application of natural substances themselves for the modification of polyamide nonwoven textiles. The basic construction characteristics of polyamide nonwoven textiles have been determined. 3-glycidyloxypropyltrimethoxysilane (GLYMO) as the precursor and paraffin for the second treatment were selected. Propolis and royal jelly in stoichiometric proportions to each of the treatments were added. The morphological characteristics of the samples were determined by scanning electron microscope (SEM) and the analysis of samples in the infrared region was performed with the addition for surface analysis (FTIRATR). For modified samples by sol-gel process or with the use of only natural means, it is assuming that they could find application in the field of medical textiles (compresses, bandages, plasters, etc.). Given this purpose, the aim of this paper was to find a formulation with as much natural composition as possible, due to ecological requirements, but also the previously mentioned high resistance of bacteria.
