Abstract

Fil antibactérien ignifuge et résistant à l'abrasion. Le fil antibactérien ignifuge et résistant à l'abrasion est obtenu par mélange uniforme d'une fibre de carbone modifiée et d'une fibre respectueuse de la peau selon un certain rapport de poids et par filage d'un fil de base à partir desdites fibres, et par réalisation d'un traitement de surface sur le fil de base au moyen d'une solution de revêtement. Un tissu constitué du fil est doux et respectueux de la peau. La solution de revêtement est préparée par mélange d'alcool polyvinylique et de chitosane, et permet d'obtenir de bons effets ignifuges et antibactériens. L'effet de revêtement de la solution de revêtement peut améliorer le regroupement des fibres, ce qui permet d'améliorer la résistance à l'abrasion du fil. La fibre de carbone modifiée est préparée par utilisation d'une fibre de carbone comme matière première, par adsorption de l'hydroxyde de calcium par la fibre de carbone, puis par production d'acétate de calcium au moyen d'une réaction d'hydrolyse d'acétate d'éthyle et d'hydroxyde de calcium pour améliorer la rugosité de la surface de la fibre de carbone et améliorer également dans une certaine mesure l'hydrophilie de la fibre de carbone et, enfin, par fixation uniforme d'une particule antibactérienne nano-inorganique à surface modifiée à la surface de la fibre de carbone par utilisation de polyuréthane comme adhésif pour fabriquer la fibre de carbone présentant de bons effets antibactériens et bactériostatiques.
