“…The improved acid dyeability of the MI samples could be attributed to availability of dyeing sites through the conversion of primary and secondary amines of b-PEI to quaternary ammonium cations under the acidic conditions. 29,31,32 Moreover, the MI samples were plasticized and made more hydrophilic by b-PEI. This effect not only increased the free volume of the MI film but also facilitated adsorption of the dyeing solution into MI film, and allowed the dye to diffuse more easily within the film.…”

Bio-based polyurethane is synthesized from biodegradable polycaprolactone, methylene diphenyl diisocyanate and 1,4-butanediol. The bio-based polyurethane is blended with branched polyethyleneimine by a solution casting method and further treated with glutaraldehyde. From nuclear magnetic resonance, Fourier-transform infrared spectroscopy, leaching tests and contact angle measurements, it was found that a semi-interpenetrating polymer network structure is induced by the glutaraldehyde treatment of the bio-based polyurethane/branched polyethyleneimine blend film, which resulting from the crosslinking of branched polyethyleneimine by imine bonds formed from the amine-aldehyde reaction between branched polyethyleneimine and glutaraldehyde. In addition, the glass transition temperature, Young’s modulus and the shape retention results show that the mechanical strength of bio-based polyurethane, which is weakened by the plasticizing effect of branched polyethyleneimine, is restored by the formation of the semi-interpenetrating network structure. We found that the bio-based polyurethane/branched polyethyleneimine with a semi-interpenetrating network shows a much higher affinity for Acid Red 4 than bio-based polyurethane, and the wet fastness of dye is significantly improved by the formation of the semi-interpenetrating network.

“…Application of synthesized nanoparticles on P, C and P-C blended fabrics was carried out using pad-dry-cure technique (Lab model – Two bowl padding mangle, EEC, India). Qualitative and quantitative confirmation of presence of elements in both pure and oxide state on fabrics was done using X-ray fluorescence spectrometer A1: (XRF) (EDX 800 Simadzu, Japan), characterization of which has been reported by Kanade and Patel (2017).…”

Purpose The main purpose of taking up this work was to see the influence of metallic nanoparticles on various fabric properties. This paper emphasizes on mechanical, aesthetic and anti-bacterial properties of the polyester, cotton and polyester cotton-blended fabric samples. Design/methodology/approach Three fabrics, 100 per cent polyester, 100 per cent cotton and polyester cotton-blended (50:50), were procured from the market. They were subjected to mild washing treatment so that the fabrics could be impregnated with copper (Cu) nanoparticles following standard procedure. The characterization of Cu nano-loaded textiles has been done using various techniques such as scanning electron microscopy for surface morphology, X-ray fluorescence spectrometer for elemental analysis and Fourier transform infrared spectroscopy for chemical composition. However in this paper, the focus is on various fabric properties and influence of this treatment on them. Antimicrobial activity was measured as per AATCC 100 quantitative method. Findings The structural properties showed changes but not major ones. The impregnation of Cu nanoparticles is nothing but a chemical treatment, and it is not uncommon to find reduction in the mechanical properties of the specimen. Here also, the mechanical properties were studied but did not reveal any significant change. The aesthetic properties for cotton fabrics showed an improvement. Improvement in the anti-bacterial activity was observed for all the fabric samples but the improvement in cotton fabric is worth mentioning. Thus, nano treatment imparts anti-bacterial property without hampering the mechanical properties of the parent textiles. Research limitations/implications It is usual to find changes in the various properties of the materials subjected to nano treatment or treatment of any sort. Though the fabric samples were subjected to similar treatment, the quantity of nanoparticles taken up by each of them was different. The reason behind this could be the difference in the crystallinity of the fabric samples. Polyester fabric showed the highest resistance, as it was least affected by the nano treatment given. Cotton fabrics composed of cotton fibers are amorphous in nature, hence showed better take-up and hence were more affected by the said treatment. Practical implications Cotton fabrics are the most favored fabric, especially in regions with hot climatic conditions. Even though these fabrics are very sought after, they have a major drawback related to the aesthetic appeal of the fabric. These fabrics have very poor resistance to the crease formation, as well as their ability to recover from the external deformation. But the study conducted on the fabric samples has shown favorable results for the cotton fabric. A significant improvement in their aesthetic and anti-bacterial activity was found. At present, textiles with nano finishing fall in niche market due to its higher cost. But finishing with in-house Cu nanoparticles may open up hygiene textiles for consumers at affordable rates. Social implications Cotton is still the most popular natural fiber in most of the tropical and sub-tropical regions. People located in these places have a natural urge to wear fabrics made from cotton fibers. Due to the hot weather, sweating is natural. However, this tends to keep the skin in humid state resulting in various skin problems, as cotton is also prone to bacterial attack. But this work has shown positive results, meaning to say that cotton fabrics show improved resistance to the bacterial activity. Hence, its suitability for hygiene applications may soon become a reality. Originality/value It is true that a lot of work is being reported on nano materials and their application to textiles for various reasons. Recently, many reports are available related to finishing of textiles using nanoparticles. However, most of the researchers are using silver nanoparticles for the same. In this work, use of in-house Cu nanoparticles has been done to treat fabric samples, which is more economical than silver nano. Also quantity required to meet desired property with Cu nanoparticles is less than the conventional treatment. This work is a sincere attempt to prepare hygienic common textiles at economical rates using continuous application technique which offers durable efficacy against human pathogenic bacterium.

“…By this way, the textile clothing sector can cope with the ever-growing consumer demands for hygienic, protective, and active wear clothing as well as it increases potential applications and value addition. On the other hand, nanotechnology is one of the upcoming sectors where lots of research works are being done with the goal of improving/altering properties of the textile materials [5]. It is an art and science of manipulating matter in a nanoscale to create new and unique materials and products.…”

The purposes of the current research were to deposit the silver nanoparticles on the surface of a textile woven fabric and evaluate their dyeing performance and antibacterial activity. The synthesis of silver nanoparticle (Ag°) is done by the in situ method. Strong alkali is used to improve functionality of cellulose before the application of silver nitrate salt (AgNO3). The silver nanoparticle is formed by reduction of ascorbic acid. Various instrumental analyses are done to prove the formation of nanoparticles on the fabric surface. The morphology of nanodeposited fabric is characterized by using scanning electron microscope (SEM), elemental composition is done by energy dispersive spectroscopy, and crystallinity of nanoparticles is obtained by X-ray diffraction (XRD). Nanodeposited fabric is then dyed with direct dyestuff (Direct Red-89). Fourier transform infrared spectroscopy analysis is done to explore the bonding phenomena of un-dyed and dyed fabrics. The dyeing performance and antibacterial activity are examined on the colored fabric to investigate the dyed fabric quality after nanoparticle deposition. Results demonstrate the improvement of 54% of color strength and 11% of dye exhaustion with excellent antibacterial activity.
