Antimicrobial Finish

A different percentage of nanoparticles of zinc oxide dispersed in a newer amino-silicone binder (poly-hydroxy-amino methyl silicone) were applied to bleached cotton khadi (handloom woven from handspun yarns) fabric to impart both ultraviolet protection and an antimicrobial finish in one step using the pad-dry-cure method, instead of using two processes for two different finishes. Amongst the varying dosages of nanoparticles of zinc oxide (1% to 5%) on the weight of fabric dispersed in poly-hydroxy-amino methyl silicone (2–10%) owf, 1% nanoparticles of zinc oxide and 4% poly-hydroxy-amino methyl silicone show ultraviolet protection factor 10 and 93–95% antibacterial reduction, whereas a 4% poly-hydroxy-amino methyl silicone and 5% nanoparticles of zinc oxide combination yields ultraviolet protection factor 20 and 99% antibacterial reduction. Thus, nanoparticles of zinc oxide at the level of 5% application with 4% poly-hydroxy-amino methyl silicone gives the best antimicrobial (99% bacterial reduction) and ultraviolet protection factor value of 20, balanced with 15–20% loss of fabric tenacity. Fourier transform infrared spectroscopy analysis reveals a complex formation between cellulose/oxy-cellulose and poly-hydroxy-amino methyl silicone that embeds nanoparticles of zinc oxide within it. Supporting reaction mechanisms proposed for both energy dispersive spectroscopy and atomic absorption spectrophotometry results further confirm the presence of zinc, potassium, and silicon on the treated cotton fabric. A wash stability test also shows the stability of the antimicrobial treatment for up to five wash cycles with 96% bacterial reduction and retention of ultraviolet protection factor of 15 after five washes. Thus, this single step combining ultraviolet protective and antimicrobial finishing of cotton fabric may be used for eco-fashion garments to protect the human skin from ultraviolet light and microbes alongside its possible uses in medical textiles to protect human body parts.

Ultraviolet Protection

A simple impregnation method was employed to obtain functional cotton fabric based on a zinc oxide (ZnO) and cellulose nanocomposite. The cellulose nanofibril suspension was utilized to reduce the agglomeration of ZnO nanoparticles (ZnO NPs) and bind them to the surface of the fiber. Scanning electron microscopy and inductively coupled plasma mass spectrometry were used to confirm the presence of ZnO NPs on the surface of the fiber. The treated cotton fabrics exhibited high ultraviolet protection factor values, which were still higher than 50 even after 30 standard washing cycles. Furthermore, the treated samples showed a modest antibacterial effect due to the presence of ZnO NPs. Meanwhile, the treated cotton fabrics showed a decrease (less than 30%) in air permeability.

Ultraviolet Protection

The protection provided by clothing against ultraviolet (UV) radiation has been the subject of considerable recent research. However, there is a lack of information concerned with the effect of weave structures and zinc oxide nanoparticles on these properties. A series of cotton fabrics differing in weave structure was produced and treated with zinc oxide nanoparticles. These fabrics were spectrophotometrically assessed and the UV protection factor calculated. It was found that while there was no significant difference in the Ultraviolet Protection Factor (UPF) in untreated samples, in samples treated with zinc oxide nanoparticles an increase was noticed in satin and granite weaves. There is no relationship between weave parameters and the UPF. Also between porosity and the UPF, no relationship was noticed. Thus the present study provides design guidelines for clothing manufacturers.

This research work was concerned with the stability of cacao dye and the application of this dye for cotton fabric dyeing by two techniques, namely direct dyeing and mordanting. The optimal conditions for cotton direct dyeing with cacao dye were carried out at 100°C for 60 min. It was observed that with an increase in the dye concentration, the ultraviolet protection factor values ranged good for cotton fabric. The results confirmed that natural dye have potential applications for fabric dyeing and producing UV protective cotton fabric.

The aim of the study was to investigate the anti-ultraviolet properties of β-cyclodextrin-grafted cotton fabrics dyed with broadleaf holly leaf extract. Flavonoids were extracted from broadleaf holly leaf by maceration and a stoichiometry of 1:1 inclusion complex with β-cyclodextrin was formed. Characterized by the fluorescence spectrum and ultraviolet spectrophotometry, the fluorescence intensities and ultraviolet absorption of the macerated extract were enhanced by increasing the amount of cyclodextrin. Cotton fabrics were grafted with β-cyclodextrin through a crosslinking reaction based on citric acid in the presence of sodium hypophosphite then dyed with the macerated extract of broadleaf holly leaf used as a natural ultraviolet absorbent. The anti-ultraviolet property of fabrics dyed by a macerated extract was characterized in terms of the ultraviolet protection factor. It was noted that the cotton fabrics grafted with β-cyclodextrin exhibit enhanced anti-ultraviolet and wrinkle recovery properties compared to the unmodified samples and show an excellent durability against 30 washing cycles, accompanied by a loss of tensile strength.

Background. The increasing emission of greenhouse gases has evoked the human being to save the ozone layer and minimize the risk of ultraviolet radiation (UVR). Various fabric structures have been explored to achieve desired ultraviolet protection factor (UPF) in various situations. Objective. In this study, the effect of various filament configurations like twisted, flat, intermingled, and textured in multifilament yarns on fabric in different combinations is assessed in order to engineer a fabric of better ultraviolet protection factor (UPF). Methods. In order to engineer a fabric having optimum UV protection with sufficient comfort level in multifilament woven fabrics, four different yarn configurations, intermingled, textured, twisted, and flat, were used to develop twelve different fabric samples. The most UV absorbing and most demanding fibre polyethylene terephthalate (PET) was considered in different filament configuration. Results. The combinations of intermingled warp with flat, intermingled, and textured weft provided excellent UVR protection comparatively at about 22.5 mg/cm2 fabric areal density. The presence of twisted yarn reduced the UV protection due to enhanced openness in fabric structure. Conclusion. The appropriate combination of warp and weft threads of different configuration should be selected judiciously in order to extract maximum UV protection and wear comfort attributes in multifilament woven PET fabrics.

In the present study, natural dye from cob of purple corn and various metallic salts have been used to identify the proper dyeing condition for attaining high quality natural dyeing along with imparting UV protection property to the dyed silk fabric. Silk fabrics dyed with cob of purple corn extract showed a violetish-pink shade, while those dyed with alum light violetish-pink shade colour. Silk substrates dyed with CuSO4 and FeSO4 gave a yellowish grey and violetish-gray colour, respectively. The fastness properties ranged from fair to good. The ultraviolet protection factor (UPF) values of silk fabric dyed with and without metal mordants ranged between very good and excellent.

Silk fabric was dyed with the colourant extracted from Laccifer Lacca Kerr. by using post-mordanting process and pad-dry technique. The effect of metal mordantats at different mordant concentration levels on their colour strength was also investigated. Silk fabrics dyed with Laccifer Lacca extract showed a light pink shade, while those dyed with alum and stannous chloride produces pinkish-red colour. Silk mordanted with CuSO4 gave a purple red colour, while those dyed with FeSO4 had a reddish-gray colour. The fastness properties ranged from fair to good, while washing fastness was poor level. The ultraviolet protection factor (UPF) values of silk fabric dyed with and without metal mordants ranged between good and excellent for dyed fabric.The results confirmed that natural dyes from Laccifer Lacca Kerr. extract have potential applications for silk fabric dyeing and producing ultraviolet (UV) protective silk fabric.
