An important basis for the creation of medical clothing is realization of the influence of various factors that arise in the interaction of elements of the system "man–clothes–production environment". Given the increasing technogenic burden on health of both medical staff and hospital patients, the assessment of the role of medical clothing in forming the energy balance of direct consumers is extremely relevant. Previous studies have experimentally confirmed the presence of energy effects of textile materials on the human body. However, determination of the nature of the impact is a complex task, which solution depends on a number of factors, such as the raw material composition, its structure, surface characteristics, etc. The purpose of our paper is to study the development of textile multifunctional materials for medical purposes and to study their energy-information impact on the human body. The following tasks have been solved in the course of the study. For use in the medical field, several samples of textile materials with antimicrobial properties, modified by herbal preparations, were obtained. Properties of textile materials that determine the possibility of their use in medical practice have been investigated. The influence of the experimental samples on the functional state of the organs and systems of human organs by use of the methods of information-wave therapy is evaluated.
PurposeThe purpose of this article is the development of up-to-date equipment for making nanocomposites for investigation of the antimicrobial properties of nanotextiles and the creation of a scientific base to choose materials of clothing with a special purpose.Design/methodology/approachInvestigations are focussed on modifying the surface of textile materials by metal ions nanoparticles (AgJ, CuJ). The work of the equipment is based on the creation of metal nanocomposites in polyethyleneglycol (PEG). It is heated up to a temperature of not more than 130ºС, followed by adding the dispersion of metal in small portions to water. Nanoparticles are uniformly distributed on material surface that provides the improvement of its characteristics.FindingsIt has been found that modifying natural fibrous materials by nanoparticles of metal ions (AgJ, CuJ) promotes increasing their bactericidal and fungicidal properties with a comparison with traditional cotton materials. Microbiological investigations of antimicrobial properties of the cotton fabric have been conducted according to their effects on staphylococcus bacteria, E. coli and fungi.Research limitations/implicationsThis research is limited to cotton fabrics. Therefore, other fabric types can be investigated to expand the data basis in the future.Practical implicationsThe main practical point of developed equipment is that it can be used for obtaining bactericidal and fungicidal properties of natural and fibrous materials modified by nanoparticles of metal ions (AgJ, CuJ). That provides new characteristics of textile materials that can be used in the future for special clothing tailoring.Social implicationsThe use of engineering equipment will allow in perspective to produce clothes with bactericidal and fungicidal properties, which can improve people’s lives through the prism of health and finished product quality.Originality/valueSpecial equipment for investigation of antimicrobial properties of nanomodified textile materials of different kinds has been engineered, and there is an opportunity to create materials with antibacterial and antifungal properties. The application of this equipment provides the receiving of new characteristics for textile materials with silver ions nanoparticles. Such properties of nanomodified materials are useful for human health and can be used in the production of various textile products.
The change in the viscoelastic properties of nonwoven web-sewn materials with a film coating during laundering was investigated. The results of the study allow recommending these materials for use in production of special-purpose corsetry.Women operated on for breast cancer (BC) are a special group of users of special-purpose corsetry. The changes in the body caused by the surgery and complex treatment require them to use special brassieres, external prostheses, and associated rehabilitation articles every day.BC occupies one of the top positions among malignant tumors in women. Genetic factors, unfavorable environment, and pathological changes in breast tissues (one woman in 5 will have some disease of the breast) are among the causes of tumors. The number of women diagnosed with BC is increasing by approximately 5.5% each year, and 37.1% of patients and 30.2% of those who died are women of working age. The peak morbidity occurs at the age of 45-60. Cases of BC in younger women have recently been increasing. Remission of the disease for 5-7 years is considered recovery (approximately 35% of the patients).The use of special undergarments after surgery does not begin immediately, but after some time based on the recommendations of the physician. An expert survey showed that 36.8% of the patients selected undergarments and prostheses in 4-6 weeks, while 43.7% did so 7-10 weeks after mastectomy. This is due to the state of health of the women and healing of the surgical wounds.So-called problem areas appear in the body due to removal of the tumor, adjacent tissues and parts of the blood and lymph collectors (Fig. 1). Acting on these areas can not only lead to discomfort, but can also cause postoperative complications and infections and wounding of the skin in the region of contact with corsetry. For this reason, the materials in the inner layer of corsetry must be hypoallergenic, not stick to the skin, prevent irritation of the skin, and create a favorable microclimate in the area of contact with the body.The problem of rehabilitation of women operated on for BC can be solved by using special nonwoven materials in problem zones.Atraumatic, two-ply nonwoven dressings with a film coating of natural fibres fabricated without additional chemical binders were developed at the Scientific-Research Institute of Nonwoven Materials (Serpukhov). They do not adhere to the surface of the wound or irritated area. Two-ply, soft-to-the-touch web-sewn materials for garments worn next to the skin were also developed. The materials were tested and certified and are used in clinical conditions and in conditions of insufficient ventilation of the space under the clothing.Since the characteristics of the materials are not well enough known, studies of the viscoelastic properties of nonwovens with a film coating with a density of 110 and 130 g/m 2 and web-sewn nonwovens with a density of 135 and 160 g/m 2 were conducted at the Kiev National University of Technology and Design (KNUTD) to demonstrate the possibility of using them in special...
