“…Finishing agents used as fabric softeners can improve softness and wearability of the fabric, and reduce the static electricity built-up on the surface of fibres if used as antistatic agents (Beal et al 1990;Agarwal et al 2011). Antimicrobial agents are used in textile finishing not only to prevent deterioration of fibre strength and quality due to microbial colonization by insects, fungi and micro-organisms but also to circumvent cross-contamination and nosocomial infections (Gao et al 2019(Gao et al , 2021. However, prolonged exposure to these chemicals, particularly in the case of overuse and even abuse of cytotoxic antibacterial agents, can cause skin irritation and damage because of the destroyed lipid membrane that serve as the external protective layer of the skin (Kosswig 2000).…”

Biosafety evaluation and quantitative determination of poly(hexamethylene biguanide) (PHMB) coated on cellulosic fabrics by Kubelka–Munk equation

It is a challenge to determine the quantity of cationic finishing agents on the surface of cellulosic fabrics. Herein, we report a direct and feasible method by Kubelka-Munk equation to quantify the cationic poly (hexamethylene biguanide) hydrochloride (PHMB) adsorbed onto cotton fabrics based on the principle of formation of a stable blue dye between PHMB and bromophenol blue sodium (BPB). The adsorption of PHMB onto cotton fabrics was first investigated and the maximum adsorption of PHMB was found to be around 8 mg per gram of cotton fabric. After being dyed with BPB, colour strength shows a positive correlation with PHMB at low concentrations (<2400 mg/L). A linear relationship with a high correlation (C(PHMB) = (K/S-0.7411)/3.4517, R 2 =0.9983) was thus established between colour strength and PHMB concentration. However, this equation should fulfill four requirements for quantifying PHMB: (1) the distribution of PHMB on the surface of cellulosic fabric should be in the form of a monolayer with the content less than 5.3 mg/g; (2) an excess of BPB dyebath should be applied; (3) the dyeing should come to equilibrium; and (4) the fabrics should be evenly dyed. Moreover, MTT assay results indicate that excess PHMB coated on cotton fabrics can cause cytotoxicity and the quantity of PHMB should not exceed 4.62 mg per gram of cotton fabrics for the purpose of biosafety. The sample can be considered noncytotoxic if the K/S value is lower than 13.2 after dyeing with BPB.

“…Nano titanium dioxide (nano-TiO 2 ) is an N-type semi-conductor with a rutile type and an anatase type. Under the catalysis of light (especially ultraviolet light), nano-TiO 2 in the water and air system can be decomposed into free-moving negatively charged electrons (e − ) and positively charged holes (h + ), and the final reaction produces highly chemically active hydrogen-oxygen free radicals (HO) and superoxide anion radicals (O 2 − ) that can attack and degrade the organic compounds in microorganisms [20]. Experimental studies conducted by Doustkhah et al (2021) showed that the admixtures of Cl in rutile TiO2 nanosheets with (110) facets (rTiO2-120) produce lower effective charge carrier masses through dispersed band shapes compared to those created by oxygen vacancy.…”

“…Therefore, it is necessary to use crosslinking agents to fix them on the fabric matrixes, which can appropriately improve the washability of nanomaterials and help achieve a long-lasting antimicrobial effect. Therefore, nanoparticles are anchored with the assistance of cyclodextrin, polysiloxane, BTCA-polycarboxylic acids, particularly 1-, 2-, 3-, and 4-butane tetracarboxylic acid, and dopamine adhesion, under electrostatic adsorption [20]. Prasad et al (2016) reported durable antimicrobial finishing obtained during the in situ synthesis of nano ZnO onto cotton fabric by the spraying or dipping process.…”

This study aimed to evaluate the durability of the photocatalytic and antimicrobial activities of ZnO and TiO2 nanoparticles (NPs)-modified 100% cotton terry textiles. SEM-EDX confirmed the long-lasting durability of the washing materials, and TGA analysis revealed that ZnO and TiO2 NPs can be found on the terry fabric surface; however, the amount of NPs decreased 10 times after 15 washes and 1.6 times after the subsequent 15 washes. The efficiency of self-cleaning properties and antimicrobial activity against five microorganisms (Staphylococcus aureus ATCC 6538, Escherichia coli ATCC 10536, Candida albicans ATCC 10231, Aspergillus niger ATCC 16404, and Bacillus subtilis NCAIM 01644) depended on UVA/B radiation intensity. The increase in UVA/B radiation intensity from 400 to 1400 µW/cm2 significantly increases the effectiveness of photocatalysis. Long-lasting self-cleaning properties characterised the tested fabric; however, stronger photocatalytic efficiency was observed in light with a greater intensity of UVA/B radiation. At the UVA/B radiation intensity of 1400 µW/cm2, a biocidal effect (R = 100%) against all tested microorganisms (E. coli, S. aureus. B. subtilis, C. albicans, and A. niger) was observed on the surface of materials. The lower UVA/B radiation intensity (400 µW/cm2) and 30 wash cycles reduce the antimicrobial activity of the material (R = 65.4–99.4%) for B. subtilis, C. albicans, and A. niger. The antimicrobial activity of washed materials modified with TiO2/ZnO nanoparticles can be increased by irradiation with a light bulb (1400 µW/cm2).

“…However, natural cotton fibers are more susceptible to bacteria, viruses, and fungi, which can trigger contacting infection and damage to cotton fibers (Liang et al 2007;Liu et al 2017;Staneva et al 2019). Therefore, it is very imperative to carry out long-term antibacterial on cotton fabrics (Gao et al 2021). Fortunately, as a kind of natural cellulose, cotton consists of polysaccharides which have plentiful -OH groups and a few carboxylic acid groups (Hou et al 2017;Przybylak et al 2016).…”

An N-halamine precursor 2-(3-(6-methyl-4-oxo-1,4-dihydropyrimidin-2-yl)ureido)ethyl methacrylate (SCMHBMA) was synthesized and grafted on cotton fabrics via atom transfer radical polymerization for antibacterial function after chlorination. The preparation and chlorinated cotton fabrics (Cotton-g-PSMA-Cl) were characterized with FTIR, XPS, SEM, and TGA. The properties of prepared Cotton-g-PSMA-Cl, including thermal property, antibacterial efficiency, durability, and stability, were systematically evaluated. The results showed that these chlorinated Cotton-g-PSMA-Cl fabrics possessed excellent antibacterial activity against E. coli. and S. aureus. After 10 washing cycles and 60 days of routine storage, active chlorine concentrations (Cl ? %) were reduced only 22% and 18%, respectively, and the reduced Cl ? % effectively reverted by simple rechlorination. This new N-halamine antibacterial cotton composite with superior antibacterial properties exhibited potential for future application in the longterm antibacterial field.
