DEVELOPMENT OF COMPLEX REUSABLE MEDICAL TEXTILE MATERIALS

Abstract

Goal. Development of complex reusable textile materials with predicted properties for use in products
for the care of bedridden patients and the choice of textile fabrics for their manufacture.

Methodology. Theoretical and experimental research is based on the basic principles of textile
materials science. Determination of structural characteristics and quality indicators was done by
experimental standard and specially developed methods. The wettability of nonwoven fabrics was
evaluated according to the indicators of the wetting angle.
Results. It was estimated that modern world trend in the development of textile fabrics for medical
purposes is the consumption of reusable products, which signifi can tly reduces the load on the ecosystem
and risks of their disposal. One of the ways to obtain such products is to create multi-layered materials
by combining individual textile fabrics with diff erent properties into one structure. Three-layer complex
materials have been developed, the upper layer of which is linen fabric with eco-friendly antimicrobial
treatment, the middle layer is a needle-punched nonwoven fabric based on natural plant fi bers, and
the lower layer is a Coolmax knitted fabric. To increase the resistance to delamination in the process
of repeated disinfection fabric was reinforced over the entire surface by quilting with the use of zigzag
stitch. In order to make a reasonable choice of the raw material composition of the nonwoven fabric
(the main moisture-accumulating layer) it was evaluated the assessment of wettability by measuring
the value of the wetting edge angle. The lowest value of this indicator and the highest rate of absorption
of a drop into structure have a nonwoven fabric which consists of 70% of linen and 30% of polyester
fi bers. For the obtained three-layer complex material, quality indicators were experimentally determined
which characterize its main functional properties and suitability for use in products for the care of
bedridden patients.
The scientifi c novelty of the obtained results lies in the substantiation of the method of obtaining
complex reusable textile materials to ensure the required level of operational properties of medical
devices.
Practical signifi cance. Complex textile materials for medical purposes are proposed, which have the
necessary hygienic and operational properties, ensure the bond strength of the layers, which allows to
expand the range of products for the care of bedridden patients.
