Antimicrobial Fibers Created via Polycarboxylic Acid Durable Press Finishing

Abstract

An N-halamine precursor, m-aminophenyl hydantoin ( m-APH), which was rendered antimicrobial through exposure to chlorine bleach, was synthesized and was applied on cotton fabric using polycarboxylic acids as crosslinking agents. Particularly, 1,2,3,4-butanetetracarboxylic acid (BTCA) with m-APH treated cotton fabric resulted in the highest increased wrinkle recovery angle and chlorine content simultaneously. Durability and rechargeability were measured through an AATCC test method and antimicrobial efficacy of BTCA/ m-APH treated cotton fabric against Gram-positive and Gram-negative bacteria showed a 6 log reduction within 1 min of contact time.

Bactericidal evaluation of N-halamine-functionalized silica nanoparticles based on barbituric acid

“…Of various antibacterial materials, N-halamine containing one or more nitrogen-halogen covalent bond is an important type of biocidal compound, and is the most promising candidate for several inherent advantages including powerful antibacterial activity, long-term stability, high durability and regenerability [6]. N-Halamine is an effective oxidizing agent, and the bactericidal action is considered to be a manifestation of a chemical reaction involving the transfer of positive halogen from N-halamine to appropriate receptor in the bacterial cells [7]. This reaction could effectively inhibit or even destroy the enzymatic or metabolic cell processes, resulting in the expiration of the microorganisms [8].…”

Rechargeable biocidal cellulose: Synthesis and application of 3-(2,3-dihydroxypropyl)-5,5-dimethylimidazolidine-2,4-dione

“…Cross-linking agents, such as polycarboxylic acids free of formaldehyde, have been developed as an alternative for the DMDMH in durable press finishing of cellulose in the last decade (Udokichdecha, Kittinaovarat, Thanasoonthornroek, & Potiyaraj, 2003;Yang, 1991;Yang & Wang, 1996;Yang, Wang, & Kang, 1997). This technique has been used to produce antimicrobial cellulose by bonding the aminohydantoincontaining precursors onto cotton with the aid of polycarboxylic acids (Kou et al, 2006;Lee, Broughton, Akdag, Worley, & Huang, 2008a). In this study, a new N-halamine precursor, 3-(2,3-dihydroxypropyl)-5,5-dimethylimidazolidine-2,4-dione, was synthesized and attached to cellulose via the cross-linking agent 1,2,3,4-butanetetracarboxylic acid (BTCA).…”

Microbial Odor Profile of Polyester and Cotton Clothes after a Fitness Session

“…This is held as a common belief; nevertheless, very few published data support this finding. Much research has nonetheless been conducted on controlling body odor by adding antimicrobials to textile fabrics (11)(12)(13)(14).…”
