Alkaline Surface Modification of Banana Stem Fibres
One of the important issues in producing composite materials with natural fibres is the modification of the surface of the fibres to enhance adhesion and interfacial bonding with polymer matrix. In this report, the effect of alkalization on the mechanical properties, thermal stability and surface morphology of banana stem fibres is examined. The results show that treatment with sodium hydroxide...
متن کاملNanofibrillated Cellulose Surface Modification: A Review
Interest in nanofibrillated cellulose (NFC) has increased notably over recent decades. This bio-based nanomaterial has been used essentially in bionanocomposites or in paper thanks to its high mechanical reinforcement ability or barrier property respectively. Its nano-scale dimensions and its capacity to form a strong entangled nanoporous network have encouraged the emergence of new high-value ...
متن کاملUsing a nitrilase for the surface modification of acrylic fibres.
The surface of an acrylic fibre was modified with a commercial nitrilase (EC 3.5.5.1). The effect of fibre solvents and polyols on nitrilase catalysis efficiency and stability was investigated. The nitrilase action on the acrylic fabric was improved by the combined addition of 1 M sorbitol and 4% N, N-dimethylacetamide. The colour levels for samples treated with nitrilase increased 156% compari...
متن کاملEnzymatic Modification of Paper Fibres
The enzymatic mode of action in paper fibre upgrading is still uncertain. In an attempt to clarify how enzymes modify pulp and paper properties, several parameters were analysed in the present work: (i) thermal analysis of the water–solid surface interactions; (ii) fibre cake permeability; (iii) particle size analysis. The results obtained suggest that enzymes modify the interfacial properties ...
متن کاملThe Sorption Behaviour of Cellulose Fibres
Cellulose fibres are the most important materials in textile finishing. Reactivity and adsorption properties of the fibres are critical for the success of the treatment. Of major interest are the properties of fibres swollen in polar liquids. Under this circumstances the less ordered regions determine the fibre properties and therefore the void size and accessible amorphous regions are supposed...
