摘要

Patient and medical staff safety has become a serious concern in recent years as the need for protection against bacterial and viral diseases has been realized. Research has shown that fabrics treated with crosslinked polyethylene glycol (PEG) produce antibacterial properties. This study investigated the influence of PEG on selected properties of four fabrics commercially available for use in protective surgical apparel: 100% polyester woven, 50% cotton/50% polyester woven, 100% polypropylene spunbonded-meltblown-spunbonded, and 50% wood pulp/50% polyester spunlace. Woven fabrics also were evaluated after laundering. Physical properties, surface characteristics, liquid barrier performance, and surface antibacterial properties were measured using accepted testing procedures. As expected, the PEG treatment physically and chemically altered the fabrics. In general, PEG-treated fabrics were significantly heavier and thicker than control fabrics and had significantly lower air permeability, porosity, and water resistance. Treated woven fabrics had more yarns per unit length, and the yarns were heavier than control fabrics' yarns. Physical changes resulted from the finish encapsulating the fibers and coating the fabric surface, as documented in scanning electron micrographs. Overall, PEG-treated fabrics had significantly lower oil repellency and water repellency than control fabrics with a fluorocarbon treatment because the PEG finish increased fabric surface energy and hydrophilicity. At pressures of 0.25 and 0.50 p.s.i., PEG-treated fabrics generally had lower synthetic blood resistance than control fabrics. All fabrics failed at 0.75 p.s.i. pressure. The synthetic blood wicked through treated fabrics, but not control fabrics. Three of the four PEG-treated fabrics inhibited bacterial growth of Staphylococcus aureus, while two treated fabrics exhibited antibacterial properties against Pseudomonas aeruginosa. After ten launderings, PEG-treated fabrics became more similar to control fabrics, indicating loss of the PEG during laundering. This finding was not unexpected, as all control fabrics had a fluorocarbon treatment which limited the adherence of the PEG finish. Properties imparted by the PEG treatment indicated that a PEG finish may be applicable in medical and hygiene applications where antibacterial properties and wicking are desirable, such as surgical gauze, diapers, and incontinence products.
