“…In general, the presence of a crosslinker causes the formation of smaller hydrogel particles than in the absence of a crosslinker. e synthesis temperature and size of the particles are inversely proportional, as macrogels are formed near room temperature [97][98][99][100] and temperatures for microgel synthesis increase to 50°C [78,80] on average, although they may rise as high as 70°C [82], 80°C [26] or even 85°C [61]. Nanogels are usually prepared at temperatures of 70°C [80][81]101].…”

“…e latter can be achieved through a low-temperature plasma treatment that provides new functional groups on bre surfaces to serve as bonding points between a hydrogel and substrate. Furthermore, the etching e ect of plasma increases the roughness of the bre surface as well as the speci c surface area of bres, resulting in the greater uptake of a hydrogel [100]. e hydrogel particle size has a signi cant e ect on the mechanical properties of a textile material.…”

“…Poly-NiPAAm was copolymerised with polyurethane and gra ed on a cellulose non-woven textile [97], or with N,N-methylene bisacrylamide (BIS) and gra ed to a cellulose support [98]. Photo-induced gra copolymerisation of poly-NiPAAm on previously plasma-treated textile substrates has also been carried out through copolymerisation with polypropylene (PP) [99], with the addition of chitosan [100] and with a polyethylene terephthalate (PET) lm [99]. Microgels based on carboxymethyl chitosan (CMCh) and PVA [112], CMC and fumaric acid [91], CMC and hydroxyethyl cellulose derivatives [92], self-assembling di-phenylalanine [83], glycol and ε-caprolactone [62], collagen [30], and polyacrylic acid and β-cyclodextrin [107] have been used.…”

This article reviews hydrogels used for the functionalisation of textile materials. Hydrogels are reviewed according to their reason for incorporation, aspects of crosslinking, stimuli-responsive characteristics and particle size. A more in-depth focus on the eff ect of hydrogel particle size is provided, where macrogels, microgels and nanogels for textile functionalisation are considered. The advantages and disadvantages of each size group are presented. Furthermore, the correlation between synthesis conditions and the sizes of hydrogel particles is discussed, in addition to the applications of macro-, micro-and nanogels to textile materials and their intended uses. Keywords: smart textiles, stimuli-responsive hydrogels, microgels, nanogels, preparation methods Izvleček

“…In all these applications, nonwoven needs to be wettable by water or aqueous-based liquids [41,42]. This is usually obtained by coating the fabric with a surfactant solution lowering surface tension of the aqueous liquid and subsequent drying of the fabric.…”

Plasma treatment has been used for surface activation and modification of textiles. The ionized, highly reactive species, such as ions, electrons, and radicals, in plasma modify the surface of the substrate material, and the composition of plasma depends on the gas used. Plasma technology is an environmentally friendly process and resource-efficient in nature. There is no solvent emission or wastewater in the process and drying processes with high energy and time consumption are not required. The textile applications of plasma include sterilization, wettability and hydrophobicity, dyeability enhancement, flame-retardant finishing, and antimicrobial properties. Plasma surface modification applied to fiber is a way to add value to a nonwoven fabric and enhance the functional performance of the final product. This chapter provides an overview of the plasma treatments of nonwovens that enhance their surface-related properties.
