“…Even today, DMDHEU is the main cross-linking agent. With magnesium chloride as the acid catalyst to initiate a reaction, it forms cross-links in the amorphous regions of the fiber [15][16][17][18][19][20][21]. Through the reaction (>NCH 2 = >NH + HCHO), free formaldehyde is released.…”

A study of single-stage antimicrobial and crease proof finishing of cotton materials has been reported. The bleached and reactive dyed cotton woven fabrics have been selected for this finishing process. The various concentrations of DMDHEU and triclosan and temperature have been selected to analyze the crease recovery and antimicrobial properties of fabric using Box-Behnken design. It was observed that increasing the concentration of DMDHEU and triclosan increases the crease recovery angle. It is also observed that the breaking strength retention properties have been reduced when increasing the concentration of DMDHEU and triclosan and temperature. It is also found that the antimicrobial effect was increased when the concentration of DMDHEU and triclosan increased.

“…One is the surface treatment of textile substrates by radiation without any additional photosensitive material and the other is the surface grafting, crosslinking, coating and laminating with these materials in radical initiating system or ionic initiating system 5–9. Through above any photo‐active process, they have acquired much information about photo‐degradation effect, antistatic effect, shrink/crease resist effect, flame resist effect, dyeability improvement, pigment dyeing, printing etc 10–17…”

The surface modifications of cellulose substrate based on the photo-induced reaction are closely related with the radicals introduced on the surface of cellulose substrates by light irradiation. We have evaluated the ability of radical formation in lyocell fabric and two water-soluble photoinitiator systems by using photoluminescence analyses. Namely, the relative quantum yields of fluorescence and phosphorescence were estimated by the integrated emission intensity under the same values of light absorbance and the identical measuring conditions. First of all the [2-(acryloyloxy)ethyl](4-benzoylbenzyl)dimethylammonium bromide (PIA) system had larger UV absorbance values below 287 nm than [3-(3,4-dimethyl-9-oxo-9h-thioxanthene-2-yloxy)-2-hydroxypropyl]trimethylammonium chloride (PIB) system at the same concentration. The relative quantum yields of fluorescence and phosphorescence emission in PIA system were smaller than those in PIB system even if the two systems had the same values of light absorbance. Therefore it was found that the PIA system was more easily transited to the triplet-state and the transited molecules reacted with the cellulose substrates more effectively. The modified cellulose fabric with 2-(dimethylamino)ethyl chloride hydrochloride (AM1) and PI system had only a little different UV absorbance and photoluminescence properties from the untreated fabric system. However, the fabric modified with 2-(4-chlorophenyl)-ethylamine (AM2) and PI system showed relatively big differences. The UV absorbance values were increased and the relative quantum yields of photoluminescence were decreased remarkably. We have acquired that the tertiary amine treated cellulose fabric were very effective in photo-induced modification of cellulose.

N-(hydroxymethyl) acrylamide (NMA) was immobilized on cotton surfaces through etherification, and then methacrylamide (MA) was grafted onto the treated surface. The coatings were characterized by ATR-IR spectroscopy and were rendered biocidal upon exposure to dilute household bleach. The treated fabrics were challenged with Gram-negative and Gram-positive bacteria; both NMA and NMA/MA-treated fabrics inactivated about 8 logs of Escherichia coli O157:H7 and Staphylococcus aureus within only 5 min of contact time. The coatings were also quite stable toward ultraviolet (UVA) light exposure and repeated laundering. Moreover, a substantial improvement in wrinkle recovery angle was obtained for the NMA/MA-treated fabrics. The new acyclic acrylamide N-halamine coating should be less expensive to produce and use than previous cyclic N-halamine coatings developed in these laboratories.
