Abstract:
In this paper was examined the influence of the alginate paste printing with the addition of alcoholic extract of Achillea millefolium L. on sorption and antimicrobial properties of knitted fabrics. For research were used two types of cotton knitted fabrics, made from the same yarn in a variety of weaves. Screen printing was performed on raw knitted fabrics and on knitted fabrics bleached with hydrogen peroxide (H2O2). The ability to retain water and relative humidity of knitted fabrics before and after printing are sorption properties that were tested. Determination of the water retention value in knitted fabrics by centrifugation method was performed according to standard DIN 53 814 and relative humidity of knitted fabrics according to ISO 139-1973. Also, the air permeability of printed knitted fabrics was tested as a parameter that significantly affects the transport of moisture through clothing. Antimicrobial properties of printed knitted fabrics were tested on bacteria Staphylococcus aureus and Escherichia coli, by using parallel streaking method (AATCC TM 147-2004). It was found that the interlock knitted fabric printed with alginate paste with the addition of 20% of alcoholic extract of A. millefolium L. demonstrated an antimicrobial effect on S. aureus, while on E. coli had no effect. It was also found that antimicrobial printing the significantly increased the water retention capacity in knitted fabrics, from 32.55% of the value for the interlock knitted fabrics bleached with H2O2 to 117.52% for printed knitted fabrics.
