N-methylol compounds, such as dimethyloldihydroxyethyleneurea (DMDHEU), are the most commonly used durable press finishing agents for cotton fabrics. Polyfunctional carboxylic acids are becoming important as non-formaldehyde replacements for these N-methylol reactants. The use of both chemistries has been shown to cause an irreversible reduction in the physical properties of finished fabric, be...

We tuned the lower critical solution temperature (LCST) of amphiphilic poly(N-isopropylacrylamide) (PNIPAAm) via copolymerization with a hydrophilic comonomer of N-hydroxymethyl acrylamide (NHMAAm). A series of copolymers P(NIPAAm-co-NHMAAm) were synthesized by atom transfer radical polymerization (ATRP) using CuBr/(N,N,N',N',N''-Pentamethyldiethylenetriamine) (PMDETA) as a catalyst system and ...

Both vacuum metal deposition (VMD) and cyanoacrylate fuming (CAF) are techniques used to visualise latent fingermarks on smooth non-porous surfaces such as plastic and glass. VMD was initially investigated in the 1970s as to its effectiveness for visualising prints on fabrics, but was abandoned when radioactive sulphur dioxide was found to be more effective. However, interest in VMD was resurre...

In the present study, cotton fabric was exposed to laser exposure at different energy levels and then the silver nanoparticles were coated on untreated and laser treated cotton fabrics. Methylene blue dye was used to detect the presence of carboxylic acid groups (-COO) on laser treated cotton and the dye absorption results were determined spectrophotometrically. ICP-OES (Inductively Coupled Pla...

An ecological and viable approach for the in situ forming silver nanoparticles (AgNPs) on cotton fabrics has been used. Silver nanocoated fabric of brownish yellow color (AgNPs, plasmon color) was characterized by scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS) and Fourier transform infrared spectroscopy (FTIR). SEM images revealed that the surface of the modified cotto...

In this study, the effects of yarn parameters, on the bursting strength of the plain knitted fabrics were examined with the help of artificial neural networks. In order to obtain yarns having different properties such as tenacity, elongation, unevenness, the yarns were produced from six different types of cotton. In addition to cotton type, yarns were produced in four different counts having th...

To investigate the antibacterial functionality of natural colorant extracts, five kinds of natural dying aqueous solutions were obtained by extraction from peony, pomegranate, clove, Coptis chinensis and gallnut using water at 90 °C for 90 min with a liquor ratio (solid natural colorant material/water, weight ratio) of 1:10. The colorimetric assay and antibacterial activity of cotton, silk, and...

India has a very rich diversity and plantkingdom is certainly a treasure house of diverse natural products. One such product from nature is the dye. In this study, natural colorants mainly flavonoids and carotenoids present in the Marigold flower (TageteserectaL.) were extracted using Soxhlet extraction method and other conventional techniques under different operating conditions. Spectrophotom...

Thermal comfort properties are very important factors for knitted fabrics. Optimized demanding during the design of garments, especially sportswear, outerwear and underwear. Knitted fabrics produced from regenerated fibers other than cotton highly preferred due to their eco-friendly, environmentally friendly superior performance properties. In this study, woven were investigated. single jersey ...

The bactericidal activity, optical spectra, electron-microscopic images and electrical resistance of cotton textile modified with bimetallic silver/copper nanoparticles (Ag/CuNPs) against the series of the microorganisms (Escherichia coli, Staphylococcus aurous, and Pseudomonas aeruginosa) are studied. NPs’ modified fabrics were produced by the developed by us method of soft heat treatment of t...
