“…Various techniques are available for the surface modification of cotton fabrics mainly including gas treatments (such as plasma treatments [19,20], ozonation [21], UV or γ Radiation [22,23], and vapor deposition [24]) and wet modifications (such as enzymatic treatment [25], chemical etching [26], insitu introduction or adsorption of nanoparticles [27,28], layer-by-layer deposition [29,30], sol-gel process [31,32], and deposition or grafting of polymers or macromolecules [33][34][35]). Comparing with gas treatments, wet modification of fabrics does not need special equipment or affect bulk properties of fiber, and thus is more suitable for industrial applications.…”

Cotton fabrics with sophisticated surface-specific properties were obtained by grafting poly(tert-butyl acrylate) (PtBA), poly(acrylic acid) (PAA), poly(oligo(ethylene oxide) monomethyl ether methacrylate) (POEOMA), poly(N,Ndimethylaminoethyl methacrylate) (PDMAEMA) and quaternized PDMAEMA (QPDMAEMA) bushes on cotton surfaces using surface-initiated activators regenerated by electron transfer atom transfer radical polymerization (SI-ARGET ATRP) of three rather different monomers in a water-ethanol solvent. Due to the different physical properties and chemical composition of grafted polymers, the properties of such obtained cotton fabrics can be tailored including mechanical properties from enhanced tensile strength to increased breaking elongation, hydrophilic/hydrophobic characteristics from superhydrophilic to hydrophobic, varied water absorption abilities, different dye adsorption capabilities and charge properties. This work presents a high potential surface modification route towards functional textiles which are expected to play an important role in the future applications.

“…FTIR-ATR of DSPCM-treated cotton fabrics Figure 1a shows the principal spectral character of cotton fabric: the peaks at 3,333, 2,895 and 1,053 cm -1 are assigned to the stretching vibration of -OH, -CH and C-O-C in the cellulosic structure, respectively (Liu et al 2013). Compared with Fig.…”

“…1 FTIR spectra of the noncovalent bonding of DSPCM onto cotton fabrics using 9 wt% CA and 8 wt% DSPCM (curve c), cotton (curve a) and covalent bonding of DSPCM onto cotton fabrics (curve b) using 9 wt% CA and 8 wt% DSPCM Cellulose N-H bend (Mocanu et al 2013); absorption peaks at 3,334 and 1,314 cm -1 are related to the N-H stretching vibration and C-N stretching vibration (Zhao et al 2013), respectively. The absorption peak at 1,710 cm -1 is assigned to the ester C=O stretching band (Liu et al 2013;Salam et al 2011); both 1,159 and 1,053 cm -1 are attributed to the C-O stretching vibration. The newly formed absorption peaks are attributed to the crosslinking interaction between DSPCM and citric acid, and O=C-NH is formed.…”

Covalent bonding and photochromic properties of double-shell polyurethane-chitosan microcapsules crosslinked onto cotton fabric

2015

The research aims at treating cotton fabrics with double-shell polyurethane-chitosan photochromic microcapsules using the coating method. FTIR indicated that an acylamino group formed between the hydroxyl of cotton fabric and amino group of the chitosan shell. The surface morphology of treated cotton fabrics revealed the compact and uniform distribution of double-shell polyurethanechitosan microcapsules on cotton fabrics. Factors affecting the covalent bonding such as the citric acid (CA) and double-shell polyurethane-chitosan microcapsule (DSPCM) concentration were studied. The K/ S value of treated fabric using 9 wt% CA increased significantly; it increased by 157.0 % compared with 5 % CA. It remained almost unchanged when the CA concentration was 11 wt%. In addition, as for 7 wt% CA-treated cotton fabric, the K/S value increased by 53.5 %. The K/S values increased by 27.29 and 42.08 %, respectively, when the concentration reached 4 and 6 wt%. The color properties of samples treated with 8 wt% concentration microcapsules increased by 44.72 %. The K/S value decreased slightly after increased launderings. It decreased by 1.73 % after 30 launderings, but did not present any changes after 40 launderings; it decreased by 8.55 % after 50 launderings. The surface morphology of treated cotton fabric samples after 50 launderings remained almost the same as the original ones. It can be speculated that the covalent bonding fastness between DSPCM and cotton fabric is good. Additionally, it possesses good thermal stability. It can be concluded that 9 % citric acid concentration and 8 % DSPCM concentration allow obtaining bright and uniform color and a quick response to UV-Vis light.

“…Accordingly, the fabrics can be designed and produced for tailored functions when coated by the desired microcapsules [116,117]. In this aspect, numerous examples have been described with regard to conferring textiles with various functions using microencapsulation technology, including durable fragrances, skin softeners, insect repellents, antimicrobials, phase change materials, and special medical applications [118][119][120][121]. In terms of AD treatment, Hui et al reported a textile based therapy functionalized with herbal medicine loaded microcapsules [90,91,122].…”

View full text Add to dashboard Cite

Atopic dermatitis (AD) is a common chronic inflammatory skin condition characterized by intense puritus and skin dryness. The pathogenesis for AD has not been fully understood to date. Complementary therapies are very popular as effective treatment for AD among clinical practitioners. This study presents a comprehensive review of published works associated with textiles-based complementary therapies for AD treatment such as wet-wrap dressing, functionalized textiles, and the application of hydrogel techniques in the textile industry to provide a better understanding of the development and design of new textiles-based transdermal therapies.
