The aim of this project is to create novel elastic knitted materials with improved comfort for medical products. In this context, warp knitted structures were produced using different weft threads laying in. The elastic warp knitted fabric produced with transverse weft threads for the whole width was used as a reference sample. It is widely used in medical products. Laying in weft threads with a partial set according to a certain repeat allows us to get structures in which there is no connection in adjacent wales in certain places. This leads to the formation of through holes in the structure. As a result of increased permeability, comfort properties are improving. The structure, functional and comfort properties of developed and reference elastic warp knitted fabrics were investigated. It was found that novel elastic fabrics have higher values of comfort indicators and provide the necessary functional properties.

In recent years motorcycling becomes more and more popular. It is known that even in relatively warm weather, moving air is cooler and constant exposure to wind when riding may cause a chilling effect that leads to hypothermia. Motorcyclists may lose the ability to concentrate and react on changing traffic conditions when they have hypothermia. We propose the use of electric heating elements in the jacket so that motorcyclist comforts increase. This element receives the energy from the worked engine of the motorcycle. It is located between the two fabrics layers (top and lining) and is made of nichrome wire. The heating is carried out by connecting this element with the power supply system of the motorcycle. In research, we use two types of packages that differ by top fabrics and two connection circuits. The studies were carried out in three different environmental conditions (air temperature, wind speed, and air humidity). Standard test methods were used for performance testing. The effectiveness of electric heating elements used in underwear space for increasing the thermal properties of motorcyclist clothing is proven. It was established that the use of an electric heating element is effective only with a thermocontroller in the electrical circuit. The results of our investigation confirmed the effectiveness of electric heating elements being used in motorcyclist jackets.
