“…The textiles containing antioxidant compounds can act as a reservoir system capable of progressively deliver the active substances to the skin layers during the process of contact with human skin [25]. These active substances can scavenge free radicals from skin degeneration and present in atmosphere, and thus protect the skin from oxidative stress, inflammation and aging [26]. The textiles possessing antioxidant function can be used for preparing clothes for people with allergies and other skin diseases.…”

Abstract:The application of biodegradable chitosan fiber for healthy and hygienic textiles is limited due to its poor acid resistance in wet processing and poor antioxidant activity. In order to prepare chitosan fiber with good acid resistance and high antioxidant activity, chitosan fiber was first crosslinked by a water-soluble aziridine crosslinker, and then dyed with natural lac dye consisting of polyphenolic anthraquinone compounds. The main application conditions and crosslinking mechanism of the aziridine crosslinker, the adsorption mechanism and building-up property of lac dye on the crosslinked fiber, and the effects of crosslinking and dyeing on the antioxidant and antibacterial activities of chitosan fiber were studied. The crosslinked fiber exhibited greatly reduced weight loss in acidic solution, and possessed excellent acid resistance. Lac dye displayed a very high adsorption capability on the crosslinked fiber and a high utilization rate under weakly acidic medium. The Langmuir-Nernst isotherm was the best model to describe the adsorption behavior of lac dye, and Langmuir adsorption had great contribution to total adsorption. Lac dyeing imparted good antioxidant activity to chitosan fiber. Crosslinking and dyeing had no impact on the good inherent antibacterial activity of chitosan fiber.

“…1a, the absorption near 1,650 cm -1 belongs to the vibration of acylamino groups in chitosan (Fig. 1b) (Mocanu et al 2013). It can be observed that some new peaks appeared in the spectra of fabrics crosslinked with polyurethane-chitosan microcapsules (Fig.…”

“…1b): 1,580 cm -1 is attributed to the 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 lack of strong chemical bonding between the functional material and textiles results in poor washing durability. The chemical crosslinking method has been employed to improve bonding fastness, including polycarboxylic acid (El-tahlawy et al 2005;Ferreira et al 2013;Fouda et al 2009;Hebeish et al 2011), citric acid monohydrate (Fu et al 2011) and glutaraldehyde (Fouda et al 2009;Mocanu et al 2013). Microcapsules can provide a strong adhesive force and more intimate contact with fabrics because of their large surface area (Ye et al 2006).…”

“…Chitosan-based microcapsules containing grapefruit seed oil extract were grafted onto cellulose using citric acid monohydrate as crosslinker (Alonso et al 2010). Chitosan was applied on cotton fabric or on chemically modified cotton (having reactive -CHO or carboxymethyl groups) to obtain easy-care characteristics and bioactive textiles (El-tahlawy et al 2005;Hebeish et al 2011;Kim et al 2003;Kulkarni et al 2010;Mocanu et al 2013). Vanillin/chitosan microcapsules were applied to the cotton fabric with citric acid as the crosslinking reagent (Yang et al 2014).…”

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.
