Development of a novel cellulose/duck feather composite fibre regenerated in ionic liquid

Textile Waste Fibre Regeneration via a Green Chemistry Approach: A Molecular Strategy for Sustainable Fashion

“…To address the issues with the current status of textile waste, we designed two ILs, [BMIM][Cl] and [MMIM][DMP], to separate textile waste blends and extract natural polymers from blended fabrics, leaving polyester unchanged, and successfully spun the natural polymers into pure cellulose and cellulose/wool keratin (w/w = 1/1) composite bres. The obtained cellulose/wool keratin composite bres have a unique morphology, with wool keratin microspheres adhered on the surface, that is different from the morphologies reported in previous studies [34][35][36] , and outstanding moisture regain, which might be due to their morphology. Acrylic was also successfully dissolved in [BMIM][Cl], indicating the capability of this IL to dissolve all hydrogen-bonded polymers, both natural and synthetic.…”

“…4a-c, the regenerated cellulose bre exhibits a smooth and even surface with a streaky appearance, of which the brillar texture was formed by the polymer chains of D-glucose units lying alongside each other 44 . Despite the consistency of the regenerated cellulose bre morphology with that reported in previous studies 34 , it is interesting that the morphology of the regenerated cellulose/wool keratin composite bre illustrated in Fig. 4d-i is signi cantly different from that reported previous studies [34][35][36] .…”

Two types of cellulose/wool keratin composite bres with the same blend ratio of 2.5 wt%/2.5 wt% were obtained via wet spinning from [MMIM][DMP], presenting a similar bre diameter but distinct morphology as a result of the different spinning speeds.…”

Keratin Associations with Synthetic, Biosynthetic and Natural Polymers: An Extensive Review

“…Similarly to the previous systems, they obtained composite fibres, with an optimum keratin amount of 10 wt. %, presenting enhanced stress (83.07 MPa), strain at break (5.14 %) and Young's modulus (8.73 GPa), which, applying a stretch during spinning, produced further improved stress (131.57 MPa), strain at break (6.61%) and Young's modulus (15.56 GPa) at 13.33% stretch [268]. Similarly, Orelma et al prepared cellulose/chicken feather keratin filaments by wet-spinning from an ionic liquid solution.…”

Ionic liquids assisted processing of renewable resources for the fabrication of biodegradable composite materials

“…Fibers with an average diameter of ∼20 μm, a high Young's modulus up to ∼22 GPa and moderately high tensile strength of ∼305 MPa were successfully spun from an 18 wt% cellulose solution in the IL. Similarly, in the interesting study of Byrne et al 131 composite fiber comprising of cellulose and duck feather was extruded from a solution of the biopolymers in the IL [(C 1 vC 2 )C 1 im]Cl via a wet spinning operation. The mechanical properties of the composite fiber was shown to be better than regenerated cellulose fibers alone with a 63.7% improvement in tensile strain.…”
