In this research the influence of the chemical form of silver on its efficiency in protecting cellulose fibres against biodegradation was studied. Elemental silver with a particle size of 30 nm, AgCl and colloidal silver were used. Biodegradation was studied using a soil burial test. The degree of biodegradation was determined by SEM, FT-IR spectroscopy and degree of polymerization. The relationship among the chemical form of silver, mechanism of its antimicrobial activity, reaction of the release of active substance and efficiency of silver cations and nanoparticles was discussed.

The goal of this research was changing of the surface morphology of bleached, mercerized cotton fabric by low-pressure CF4 plasma to produce a high degree of adhesion for adsorption of silver nanoparticles. Plasma functionalized fabric treated with 30 nm silver particles shows good antimicrobial effectiveness to Enterococcus faecalis and Pseudomonas aeruginosa. Plasma functionalized dyed fabric does not show an evident change of dyeability.

The cotton fabrics were bleached with peroxyacetic acid in different processes. Impregnation and bath processes were compared at different concentration of the bleaching bath, at different temperatures and times of treatment. Pad-steam bleaching was also included. The analysis of bleached fabrics revealed which conditions give the optimal whiteness values at minimal damage of cotton fibres.

A broad spectrum of the same, however, structurally different monofilament fabrics assures referential samples required for the evaluation of UV protection properties. The parameters of transmission and reflection were measured, absorption and ultraviolet protection factors (UPF) were calculated. The values calculated on the basis of a determined mathematical model matched well with the measured values and can together represent the basis for a successful planning of fabrics with suitable UV protection properties.

This article reviews some of the contemporary antimicrobial agents in textiles. According to their mechanism of antimicrobial activity, toxicity, durability and ecological acceptability, they are divided into different groups: the biocides and the biostates, the leaching and the bound antimicrobials, the controlled released and the barrier forming agents, as well as those of poor and of good washing resistance. The synthesis of antimicrobial agents, whereby the leaching antimicrobials have been replaced with the bound antimicrobials was exposed.
