CAPILLARITY OF HOSPITAL PROTECTIVE TEXTILES

In this paper, the moisture management, as one of the key performance criteria regarding the fabric comfort, was determined on cotton fabrics aimed to be used in the hospital environment. For that purpose, the commercial cotton fabrics for operative clothing and hospital bedding, as well as standard cotton fabric treated with different cationic agents for antimicrobial protection were researched. The antimicrobial properties of standard cotton fabrics were achieved by cationization with 3-chloro-2-hydroxypropyl-trimethyl ammonium chloride (CHPTAC), and reactive polyammonium compounds Rewin OS ; and by treatment with quaternary ammonium long chain compounds, N-cetylpyridinium chloride (N-CPC) and cetylpyridinium bromide (CPB), which act as surfactants and antiseptics. Standard cotton fabric has excellent hydrophility, fast absorption, fast spreading and large spread area at bottom surface and good one-way transport. It is characterized as Moisture management fabric. Hospital white fabric for beddings has water repellent treatment ; however, it is breathing and can be characterized as Water penetration fabric. Hospital green fabric for gowns and instrument covers, due to dyestuff blocking the active groups have smaller absorption, and can be characterized as Fast absorbing and quick drying fabric. Cotton fabrics have negative zeta potential. By cationization, the surface charge has changed, as well as antimicrobial activity. On MMT both cationized cotton fabrics are characterized as Fast absorbing and quick drying fabric, having fast wetting, fast absorption, large spreading area and fast spreading, but poor one-way transport. For the QAC treated fabrics this effect is more enhanced. However, these fabrics have excellent antimicrobial activity even after desorption. Based on the results of capillarity, zeta potential and antimicrobial activity it is to suggest CPB treatment of cotton fabrics.
