This study describes the use of cyclodextrin (CDs) as a finishing agent of polypropylene biomaterial (PP) by means of 1,2,3,4-butanetetracarboxylic acid (BTCA) as crosslinking agent. Grafting happened by the formation of a crosslinked polymer formed between BTCA and CDs. This polymer physically adhered to the fibers network and was resistant to hot water washings. We study the influence of parameters involved in this specific textile processing. These parameters include the curing conditions (temperature, time) and also the nature of the reactants which are 1,2,3,4-butanetetracarboxylic acid (BTCA), citric acid (CTR) and polyacrylic acid (PAA), applied as crosslinking agents. Modified PP fibers were then characterized by evaluating the contact angle with a polar liquid and by studying the hysteresis of damping of PP fibers (Cahn balance) with various grafting rates. Infrared spectroscopy (ATR) and morphological (SEM) studies displayed the presence of the crosslinked CD polymer that coated the fibers, and permitted to evaluate the chemical heterogeneity of the grafted surfaces. A mechanical characterization of the PP fabrics grafted with various proportions of CDs was accomplished, by traction via a tensile-test. Finally a topographic study of PP grafted surfaces was approached by atomic force microscopy (AFM) which permitted to evaluate the roughness and the chemical heterogeneity of the grafted surfaces.
