Health-Improved Textiles Obtained by Heat Surface Ecodyeing Treatments

Abstract

The central idea of the present research aims at achieving textile substrates through an efficient inclusion of a wild black cherry extract into the grafting agent-monochlorotriazinyl-β-cyclodextrin (MCT-β-CD). The methodology consists in a permanent/irreversible entrapment onto the fibres surface of the natural extract through inclusion mechanism. Exhaustion and sonication dyeing procedures were used alternatively. The obtained materials were characterized, by FT-IR and BET analysis. The experimental results reveal good adsorptive feature of the samples, due to a higher specific surface created by the inclusion complex (MCT-β-CD-dye pigment). An efficient blocking of the natural dye pigment molecules into the grafting agent’s cavity (MCT-β-CD), assumed both a stable dyeing and antimicrobial potential. The results obtained by this ecologic surface grafting method will contribute to novel key points in producing healthy natural textiles, as alternatives for single use textiles. The results provided by this research will be used as starting point for a future study targeting the obtaining of textile supports with antimicrobial performance. Other investigations like washing, rubbing and colour fastness, highlighted that dyeing treatment by sonication is extremely efficient and could be successfully applied to such items, in boosting developments.
