Zusammenfassung: | The invention relates to a process for making a woven fabric with antistatic properties, meant to be used in antistatic composite structures for textile sensors. According to the invention, the process consists in preparing a dispersion from a solution containing polyethylene glycol, ethanol, distilled water and copper or nickel micro-particles and a polyvinyl alcohol solution, followed by applying the dispersion by padding, controlled reticulation using a heating system based on electric resistors, at a temperature of 120...140°C, for 5...2 min, resulting in an antistatic textile surface with surface resistance values of 10...10Omega.
Invenţia se referă la un procedeu de obţinere a unei ţesături cu proprietăţi antistatice destinată utilizării în structuri compozite antistatice pentru senzori textili. Procedeul, conform invenţiei, constă în prepararea unei dispersii dintr-o soluţie conţinând polietilenglicol, etanol, apă distilată, microparticule de cupru sau nichel şi o soluţie de alcool polivinilic, urmată de aplicarea dispersiei prin metoda fulardării, reticulare controlată utilizând un sistem de încălzire pe bază de rezistenţe electrice, la o temperatură de 120...140°C, timp de 5...2 min, rezultând o suprafaţă textilă antistatică având valori ale rezistenţei de suprafaţă de 10...10Ω. |
