“…Moreover, reaction efficiency decreases by increasing the amount of grafted PMAA on the fabrics. Vainburg et al26 have declared that a stable antimicrobial effect on cellulosic textile materials is obtained at a low QAS content: 4–6 mg of preparation per gram of fabrics. On the basis of the above‐mentioned one can conclude that a graft yield of PMAA of 8% is quiet enough for imparting high biological activity to nylon‐6 fabrics.…”

A simple, efficient, and practically applicable functional approach for improvement antimicrobial properties of nylon-6 fabrics and increase the washing durability of biofunctions was developed. This finishing approach is based on grafting of the fabrics with methacrylic acid (MAA) to create additional carboxylic groups in nylon-6 macromolecules, followed by subsequent reaction with dimethylalklbenzyl ammonium chloride (DMABAC) solution under alkaline conditions. The carboxylic groups react with cationic agent through ionic interaction, which led to the immobilization of QAS on nylon-6 fabrics. This immobilization was proofed through determination of nitrogen content, applying scanning electron microscopy (SEM), and FTIR microscopy. The effect of treatment conditions on salt uptake (SUT) on nylon-6 fabrics and reaction efficiency (RE) was investigated. The antimicrobial assessment of regular and grafted with PMAA nylon-6 fabrics treated with DMABAC revealed that both types of fabrics are characterized before washing, by quite strong biocide effect on Bacillus mycoides, Escherichia coli and Candida albicans. The role of grafting nylon-6 fabrics before treatment with salt on durability of antimicrobial functions seems to be more significant as the samples were repeatedly washed. Even after Laundring 10 times the grafted samples could still provide 80%, 100%, and 87.5% microbial reduction against B. mycoides, E. coli and C. albicans, respectively, in contrast with 42.6%, 65.6%, and 42.5% in case of regular nylon-6 fabrics.

“…It is seen from the data listed in Table III that the increase in weight loss % from 11 to 25% in the case of R‐PET and PEG‐M‐PET and from 10 to 20% in the case of blends is not accompanied by a noticeable increase neither in the salt uptake on the fabrics nor in the antimicrobial activity of the finished samples (Table V). Vainburg et al5 have declared that a stable antimicrobial effect on cellulosic textile materials is obtained at a low DMABAC content: 4 to 6 mg of preparation per gram of fabric. Based on the above‐mentioned one can conclude that a weight loss of 5–7.5% quiet enough for imparting high biological activity to PET fabrics, irrespective of the type of sample used.…”

“…More promising and widely used method for imparting bioactive features to PET fibers is the preliminary modification of ready‐made articles via reaction in the polymer chain or by grafting of ionogenic and nonionogenic monomers, with the objective of increasing the content or creating on the fibers new functional groups, which are able to react with biocides 5–11. Ito et al12 prepared insulin‐immobilized PET by the hydrolysis of PET and the subsequent reaction with insulin.…”

“…One of the effective ways of obtaining antimicrobial fibers and textile articles is modifying man‐made fibers with quaternary ammonium compounds. These substrates have a broad spectrum of antimicrobial action with respect to both fungi and bacteria 5. Quaternary ammonium salts (QAS) are readily soluble in water, they are adsorbed well by fibers, and the definite toxicity inherent to these compounds can be considerably reduced by including them into polymer structure.…”

An effective two‐stage method has been developed for imparting antimicrobial properties to regular polyethylene terephthalate (R‐PET), polyethylene glycol modified polyethylene terephthalate (PEG‐M‐PET), R‐PET/Cotton blend (R‐PET/C) and PEG‐M‐PET/Cotton blend (PEG‐M‐PET/C) fabrics. The method consists of partial hydrolysis of the fabrics to create carboxylic groups in PET macromolecules followed by subsequent reaction with dimethylalkylbenzyl ammonium chloride (DMABAC) under alkaline conditions. The reaction conditions such as pH, reaction temperature and time, carboxylic content, and DMABAC concentration were studied. Characterization of the finished fabrics was carried out through scanning electron microscopy (SEM) and Fourier transform infrared spectra (FTIR). All the modified PET fabrics showed excellent antibacterial activity towards Gram‐positive (Bacillus mycoides), Gram‐negative (Escherichia coli), and nonfilamentous fungus (Candida albicans). The achieved antimicrobial functions on the PET fabrics are durable in repeated laundering processes. Even after laundering 10 times the fabrics could still provide more than 85% of its antimicrobial activity against B. mycoides, E. coli, and C. albicans. © 2008 Wiley Periodicals, Inc.
