The invention deals with a method for obtaining
antimicrobial resistant cellulose textiles by means of the
grafting of monochlorotriazinyl - β – cyclodextrin,
simultaneously with spinning, on cellulosic hemp
materials. The covalent bonding provides hosting cavities
that can include a large variety of chemicals for specific
nanometrical superficial finishing. As guest is used
allantoin (C4H6N4O3 - 5-ureidohydantoine or
glioxyldiureide). The method has two stages: the

support – by means of a pad-dry-cure technique -, and the
inclusion of the antimicrobial agents - by impregnation in
solution. This nanofinishing is antimicrobial effective
against some microbial strains (Escherichia coli,
Staphylococcus aureus, Pseudomonas aeruginosa,
Candida albicans) and washproof. The invention has as
potential industrial application the obtaining of summer
clothes, for sport and indoor activities clothes, as well as
clothes for special medical conditions (photosensitivity
and skin deseases).
