“…Similar to sodium alginate, chitosan is also widely used as a novel biomaterial which is biocompatible, biodegradable and non-toxic (Qin 2004). Previous research has reported that chitosan can be applied to textile printing for improving colour yield, colour fastness and anti-bacterial function (Qin 2004;Ye et al 2005;Lim and Hudson 2004;Jocic et al 2005;Choi et al 2005). Therefore, chitosan may be used as a chemical for preparing the printing paste for digital ink-jet printing of cotton fabric.…”

Atmospheric pressure plasma (APP) treatment was applied as a pretreatment process to enhance the deposition of printing paste in order to improve the final colour properties of digital ink-jet printed cotton fabrics. Three printing pastes containing natural polymers, i.e. (1) sodium alginate, (2) chitosan and (3) sodium alginate-chitosan mixture, were prepared separately. After APP treatment, cotton fabric was padded with different printing pastes prior to digital ink-jet printing. Experimental results showed that APP pretreatment could increase the colour yield of the digital ink-jet printed cotton fabric significantly even after washing. In addition, other properties such as colour fastness to crocking, colour fastness to laundering, outline sharpness and anti-bacterial properties were also improved when compared with those of the control cotton fabric printed without APP pretreatment. However, the influence of printing paste on the colour properties of the digital ink-jet printed cotton fabrics depended very much on the composition of the printing paste. The scanning electron microscope images evidenced that the APP treatment could enhance the deposition of printing paste on the cotton fabric surface as proved qualitatively by both the contact angle and wetting time measurement as well as quantitatively by both the X-ray photoelectron spectroscopy and carboxyl group/nitrogen content analysis.

“…Similar complexes can also be formed with chitosan (Mw not given, DA = 0.15)-sulfated surfactant-like dyes [77]. These complexes are soluble in chitosan excess but a stoichiometric precipitate is formed in the dye-excess region of the phase diagram.…”

“…Also, the increment in wool is greater than that in silk samples; this can be related to the increasing intensity of the amino groups with increasing chitosan concentrations. These groups have been reported to act as a built-in catalyst on the treated samples and to imparting a cationic surface which attracts the oppositely charged dye anions leading to enhancement the dyeability and the light fastness (Jocic et al, 2005) It has been reported that dyeing properties depend mainly on the dye concentration and nitrogen content of chitosan pretreatment within the surface of the fabrics (Phattanarudee & Kiatkanjornwong, 2008). This has been explained by interaction between the protonated amino groups of chitosan and anionic dyes via ionic interaction through an ion exchange process, and hence the color difference (ΔE) values decrease.…”

This work has focused on developing eco-friendly treatments for modifying the fabric surface. Thus; we studied in details the effect of individual and combined uv\ozone and chitosan on wool and silk fabric samples. All the treated samples are characterized and evaluated by: i) Fourier transform infrared spectra with attenuated total reflection analysis (FTIR-ATR), ii) Performance properties, iii) Mechanical measurements, and iv) Dyeing characteristics using two different dye classes namely, reactive dye (C.I. Reactive Orange 69) and direct dye (C.I Direct Yellow 11) applied on both wool and silk samples modified with the above mentioned three techniques.
