Biocolourants from onion crop side streams and forest mushroom for regenerated cellulose fibres

چکیده
Biocolourants and sustainable textile materials have gained growing interest. Traditionally natural dyes been used for dyeing wool silk, but demand cotton regenerated cellulose fibres increases because of their popularity especially in clothing. This study expands the dye research to one latest innovations among cellulosic fibres, i.e. Ioncell®. It explains first time dyeability Ioncell–F with biocolourants compares results three other viscose, bamboo viscose lyocell, using protein fibre as a reference. The colourants from food side stream, yellow onion (Allium cepa cv. Settonia) forest mushroom Cortinarius semisanguineus were dyes. composition each sources was analyzed detail. Methods exhaust (80 °C, 1 h), alum, FeSO4 tannin mordants, high temperature pressure (130 h) applied. colour dyed studied CIE L*, a*, b*, C*ab, hab K/S (λ420/480 nm) values. colourfastness washing light examined according ISO standards. showed that strongest obtained polyphenols acidic conditions, whereas anthraquinones remained revealing hindering forces between fibre. values at highest iron aluminium mordanted samples, which indicate metal ions’ ability stabilize organic compound’s structure form strong coordination bonding dye. varied poor moderate. exhaustion levels different very little. search colourants, applications long lifetime artefacts is strongly supported by sustainability goals, colourant production connection agricultural industries support this emerging field.

Correlation of Regenerated Cellulose Fibres Morphology and Surface Free Energy Components
Structural parameters of raw and pre-treated viscose, modal and lyocell fibres were determined using X-ray diffraction, and compared with data obtained from iodine adsorption and tenacity measurements. A good correlation was found between iodine adsorption and structural changes. These structural parameters are correlated with surface thermodynamic parameters obtained by surface tension experim...
متن کاملRegenerated cellulose for controlled oral drug delivery
The performance of regenerated cellulose (RC) films and capsules was investigated for their applications in oral controlled drug delivery. Regenerated cellulose films were prepared by non-solvent-mediated, phase inversion of native and depolymerized cotton linter solutions (methylolcellulose; cellulose dissolved in dimethyl sulfoxide/ paraformaldehyde solvent system) in water as well as by phas...
متن کاملHighly porous regenerated cellulose hydrogel and aerogel prepared from hydrothermal synthesized cellulose carbamate
Here, a stable derivative of cellulose, called cellulose carbamate (CC), was produced from Kenaf (Hibiscus cannabinus) core pulp (KCP) and urea with the aid of a hydrothermal method. Further investigation was carried out for the amount of nitrogen yielded in CC as different urea concentrations were applied to react with cellulose. The effect of nitrogen concentration of CC on its solubility in ...
متن کاملOxidized Regenerated Cellulose Resembling Vaginal Cuff Abscess
INTRODUCTION Application of oxidized regenerated cellulose is commonly performed in laparoscopy to achieve hemostasis during surgery. The appearance of an abscess resembles oxidized regenerated cellulose, causing imaging studies to be difficult to interpret. CASE DESCRIPTION We describe the cases of 3 patients who underwent oxidized regenerated cellulose placement during laparoscopic gynecolo...
