Thesis Title: The influence of blend level on the effectiveness of antibacterial fiber
Thesis Author: Katherine Vorlicek
Abstract: This research investigated the antibacterial efficacy and durability of 50/50 acrylic/cotton and 100% acrylic dyed hosiery fabrics containing three blend levels of antibacterial acrylic fiber. The Amicor antibacterial.acrylic fiber, produced by Acordis Acrylic Fibers, investigated in this study contains 2 % of the antibacterial agent Triclosan. Blends of 16.67,25.00, and 33.33% Amicor antibacterial acrylic fiber were examined to determine the effect different percentages of antibacterial acrylic fiber had on the bactericidal activity of the fabrics examined in this study. Furthermore, acrylic/cotton and acrylic fabrics containing antibacterial acrylic fiber were compared to determine if fiber type influenced the bactericidal ability of the treated fabrics. The results of this research show that all blend levels of Amicor antibacterial fiber were equally effective in reducing bacterial counts to 50 laundry cycles. Both fabric blends (50/50 acrylic/cotton and 100% acrylic), at all blend levels of antibacterial fiber (16.67,25.00, and 33.33% Amicor) exhibited over 98% percent bacteria reduction when tested against Staphylococcus aureus and Klebsiella pneumoniae. However, dyed control fabrics, which did not contain antibacterial fiber, also exhibited excellent bactericidal activity (over 94%) against S. aureus and K. pneumoniae when tested prior to washing and at 5 wash cycles. Based on the high percent bacteria reduction for the control fabrics, this study concluded that the dye is antibacterial against S. aureus and K. pneumoniae. Furthermore, results show fiber type did not influence the bactericidal ability of the fabrics examined in this study.
