The contact resistance of two interlacing electro-conductive yarns embedded in a hybrid woven fabric will constitute a problem for electro-conductive textiles under certain circumstances. A high contact resistance can induce hotspots, while a variable contact resistance may cause malfunctioning of the components that are interconnected by the electro-conductive yarns. Moreover, the contact robustness should be preserved over time and various treatments such as washing or abrading should not alter the functioning of the electro-conductive textiles. The electrical resistance developed in the contact point of two interlacing electro-conductive yarns is the result of various factors. The influence of diameter of the electro-conductive stainless steel yarns, the weave pattern, the weft density, and the abrasion on the contact resistance was investigated. Hybrid polyester fabrics were produced according to the design of experiments (DoE) and statistical models were found that describe the variation of the contact resistance with the selected input parameters. It was concluded that the diameter of the stainless steel warp and weft yarns has a statistically significant influence on the contact resistance regardless of the weave. Weft density had a significant influence on the contact resistance but only in case of the twill fabrics. Abrasion led to an increase in contact resistance regardless of the weave pattern and the type of stainless steel yarn that was used. Finally, a combination of parameters that leads to plain and twill fabrics with low contact resistance and robust contacts is recommended.

One of the main causes of disabling deficits is neurological affections. Many times, the evolution of the condition leads to a diminution of the patient’s life quality. Functional electrical stimulation (FES) is part of the neurological rehabilitation process that comprises all the actions one can take in order to increase a patient’s integration and autonomy degree from a social and financial point of view. FES is a method based on substituting the commands that are usually transmitted by the nervous system with an electric impulse. The use of such a method on different body areas required the development of some adequate devices, starting with the stimulator itself and finishing with the way in which the stimulus is conveyed to the effectors. Textile materials that incorporate sensors and, mainly, the clothing products that have such components in their structure, have a high applicability potential; they can be used for preventing illnesses and for the rehabilitation of seniors, of people who are confined to bed, sportsmen, people who suffer from long-term illnesses, disabled people, thus diminishing the time one spends in the hospital. A possible solution for manufacturing incorporated textile electrodes consists in the insertion of some electro-conductive yarns onto textile surfaces by using a variety of technologies. The project approaches the use of knitting, a widespread textile technology. The incorporated knitted electrodes were accomplished by applying the knitting technology on single circular small diameter machines. Thus, we were able to obtain a variety of knitted articles as two-dimensional or three-dimensional tubular knitted fabric. Their dimensions, structures, and parameters correspond to the typo-dimensions of the human body and to the purpose for which the clothing product was designed. The knitted versions were tested by using a Microstim2v2 (PW = 300 μs, 40 Hz) neurostimulator for which the current intensity was adjusted to approx. 30 mA.

The technology of electrically conductive fibre production has been devised at the Textile Research Institute (Łódź, Poland), and has patent protection in Europe and the USA. Electrically conductive nonwovens (stitch-bonded and needled) made from these fibres differ from each other not only in production technology, but also in electric properties. Measuring the shielding effectiveness of these fabrics proved a possibility of their application as electromagnetic shields. Their practical application was presented for physiotherapy where short-wave and microwave diathermy is used.

W Instytucie Włókiennictwa w Łodzi (Polska) opracowano sposób wytwarzania włókien elektroprzewodzących objęty ochroną patentową w Europie i USA. Włókniny wytworzone z tych włókien metodą igłowania i przeszywania, różniły się właściwościami elektrycznymi. Pomiary skuteczności ekranowania tych wyrobów wykazały możliwość ich zastosowania jako ekranów pól elektromagnetycznych. Praktyczne zastosowanie zostało z powodzeniem sprawdzone w fizykoterapii, dla przypadku stosowania diatermii krótko- i mikrofalowych.
