The efficiency of an adsorbent has been investigated for the removal of released textile dyes and micro-organisms during household textile laundering. The results show that laundering with the addition of the striped adsorbent and IEC A* detergent reduced the higher log step reduction of Sa (more than 4 log steps) compared to laundering without detergent (2.62 log step reduction), or laundering in a blind bath (1.61 log step reduction). The sorption efficiency of the functionalised nonwoven adsorbent is limited, capable of adsorption of a maximum of 0.1 g/L of reactive dye from the washing bath. Laundering in a bath of 20 °C, with the addition of a striped textile adsorbent or in combination with detergent IEC A*, does not prevent biocontamination of the washing bath and textile load.

The possibility of marking and engraving on cloth with CO2 laser has been studied. For this purpose a methodology of experiments was developed in which a matrix of nine squares measuring 1: 1 cm and a laser beam velocity and power of 2-26 W and 100-350 mm / s, respectively.
