“…Liquid drops split into tiny droplets before depositing on the substrate. [20][21][22][23] Electrospraying has been used widely in areas such as ink-jet printing, [24,25] fabric functionalization, [23,[26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41] making biomimetic materials, [42,43] and fabricating fuel cells. [44] Since the deposition rate can be controlled through adjusting the flow rate of liquid, electrospraying offers opportunities to control the coating depth on fabric, which is useful for making directional water fabrics.…”

Fabrics with automatic one‐way water transport ability are highly desirable for applications in daily life, industry, health, and defense. However, most of the studies on one‐way water transport fabrics only report the qualitative water transport results. The lack of quantitative measure makes it hard to assess the directional transport quality. Here, it is proved that a hydrophilic fabric after being electrosprayed with a thin layer of hydrophobic coating on one side shows one‐way water transport ability. By using moisture management tester, the water transport property is qualitatively characterized and the effect of hydrophobic fabric layer thickness on one‐way water transport feature is examined. The hydrophobic fabric layer thickness is found to play a key role in deciding the one‐way transport ability. When a plain woven fabric with an overall thickness of 420 μm and average pore size of 33 μm is used as fabric substrate, a hydrophobic fabric layer thickness between 22 and 62 μm allows the treated fabric to show a one‐way droplet transport feature. A one‐way transport index as high as 861 can be attained. The one‐way water transport is durable enough to withstand repeated washing. This novel fabric may be useful for development of “smart” textiles for various applications.

“…A high voltage is supplied to the solution in the needle. Due to the identical charge the droplets repel each other, then due to instability at the needle tip the droplets start dispersing into micron-sized particles and are deposited on oppositely charged surfaces, while the solvent is evaporated rapidly [20]. The method of producing chitosan nanoparticles through emulsion droplet coalescence is described in Figure 8.…”

Due to the versatility of its features and capabilities, chitosan generated from marine crustacean waste is gaining importance and appeal in a wide variety of applications. It was initially used in pharmaceutical and medical applications due to its antibacterial, biocompatible, and biodegradable properties. However, as the demand for innovative materials with environmentally benign properties has increased, the application range of chitosan has expanded, and it is now used in a variety of everyday applications. The most exciting aspect of the chitosan is its bactericidal properties against pathogens, which are prevalent in contaminated water and cause a variety of human ailments. Apart from antimicrobial and water filtration applications, chitosan is used in dentistry, in water filtration membranes to remove metal ions and some heavy metals from industrial effluents, in microbial fuel cell membranes, and in agriculture to maintain moisture in fruits and leaves. It is also used in skin care products and cosmetics as a moisturizer, in conjunction with fertilizer to boost plant immunity, and as a bi-adhesive for bonding woods and metals. As it has the capacity to increase the life span of food items and raw meat, it is an unavoidable component in food packing and preservation. The numerous applications of chitosan are reviewed in this brief study, as well as the approaches used to incorporate chitosan alongside traditional materials and its effect on the outputs.

“…CHT has also been utilised for achieving anti-felting properties of wool [19]. Recent studies reported successful coating of CHT on wool nonwoven using electrospraying technique and pad-dry-cure method [20,21]. Thecurrent study reports paddingof CHTontothe 100% wool nonwoven matrix developed, followed by an evaluation ofblood uptake and antimicrobial properties related to wound dressing.…”

Textile substrates can be treated with suitable polymer solutions to enhance the surface functionality. This paper highlights the application of chitosan (CHT) on 100% wool nonwoven matrix using traditional pad-dry-cure method; and its potential application in medical textiles, specifically wound dressing products. 100% wool nonwoven matrices were prepared by a needle punching process and applied with different concentrations of CHT. The blood uptake and antimicrobial efficacy was evaluated for the CHT-treated samples. It was shown that 0.3% CHT-treated samples demonstrated good absorbency and excellent antimicrobial properties.
