Abstract:

In the flame retardancy of the biopolymer matrix and natural fibre reinforcement containing green composites, researchers face multiple challenges, such as low thermal stability, the candlewick effect of fibres and compatibility issues. Cellulosic fibres have been shown to have char-promoting properties and to advantageously interact with intumescent systems. In this work, melamine-polyphosphate was combined with neat or flame-retardant-treated cellulosic fibres differing in fibre length to obtain intumescent flame retarded poly(lactic acid) composites. The effect of the cellulose fibre length

Abstract Lyocell is a man-made, regenerated cellulosic fibre developed through cellulose dissolution in non-derivative solvents. Hemp offers a preferential source of cellulose for lyocell production as it is considered an environmentally friendly agricultural crop, requiring less water, fertilizers, pesticides, and herbicides than other crops and sequesters carbon dioxide (CO2) from the atmosphere. There are currently no Canadian sources of domestically manufactured lyocell filament or staple fibres. Our goal is to manufacture 100% lyocell fibre and to demonstrate techniques for pulping and so

Abstract:

Circularity of cellulose-based pre- and post-consumer wastes requires an integrated approach which has to consider the characteristics of the fibre polymer and the presence of dyes and additives from textile chemical processing as well. Fibre-to-fibre recycling is a condition to avoid downcycling of recycled material. For cellulose fibres regeneration via production of regenerated cellulose fibres is the most promising approach. Textile wastes contain dyes and additives, thus a recycling technique has to be robust enough to process such material. In an ideal case the reuse of colorants can be

Abstract Cellulose and starch are two natural biological sources that have potential as bioplastic raw materials. Cellulose and starch show tremendous potential to reduce environmental pollution caused by conventional plastics.

The modification of cellulose into cellulose acetate makes the resulting bioplastics have better mechanical properties. In addition, bioplastics can be composite with starch to have a stronger matrix. Cellulose-starch bio-composites have also be

Abstract:

Strong and ductile barrier materials based on cellulose are predicted to be of great importance in a sustainable society. Such materials can be achieved by partial conversion of the cellulose of wood fibres to dialcohol cellulose. The chemical modification does not compromise the macroscopic fibre structure and still allows for rapid processing by conventional papermaking.

This article explores an easy and economically viable route for cellulose fibre isolation from the stem of Pennisetum polystachion and its utility as reinforcement filler in the polymer matrix for the development of biocomposites. The cellulose fibre was isolated by alkali treatment, followed by chlorine free bleaching using hydrogen peroxide. The SEM and FTIR analyses revealed removal of hemicelluloses and lignin. The X-ray diffraction analysis showed increased crystallinity and the TGA and DTG curves indicated greater thermal stability of the isolated fibre compared to the raw fibre. The cel

Steel is costly and detrimental to the environment when used as a reinforcement. Another technique for reinforcing concrete is fibre reinforcement. Fibre is a small amount of reinforcing material with specific properties. Fibre-reinforced concrete has several uses and is available in several shapes. Cellulose fibre, glass fibre, steel wire fibre and steel raw material have the following percentages: 0.5%, 0.7%, and 1%; 0.3%, 0.6%, and 1%; and 0.5%, 1%, and 1.5%, respectively.

Abstract:

Due to the increasing discussion about sustainable and CO2-reduced materials, the demand for cellulose-based fibres as a reinforcing component in thermoplastic composites has increased considerably. Knowledge about the possibilities of modifying fibres for improved adhesion to the plastic matrix is essential in this context. The fibre/matrix adhesion in cellulose fibre-reinforced polymers is of considerable importance for the design of composite materials. Unfortunately, there are no standards for many essential methods to determine fibre/matrix adhesion. In this review article, various method

Abstract:

Risks from rockfall and land sliding can be controlled by high-tensile steel nets and meshes which stabilise critical areas. In many cases, a recultivation of the land is also desired. However, high-tensile steel meshes alone are not always sufficient, depending on the location and the inclination of the stabilised slope, to achieve rapid greening. Cellulose fibres exhibit high water binding capacity which supports plant growth. In this work, a hybrid structure consisting of a nonwoven cellulose fibre web and a steel mesh was produced and tested under outdoor conditions over a period of 61 wee

Abstract:

The use of cellulose nanofibres as high-strength reinforcement in nano-biocomposites is very enthusiastically being explored due to their biodegradability, renewability, and high specific strength properties. Cellulose, through a regular network of inter- and intramolecular hydrogen bonds, is organized into perfect stereoregular configuration called microfibrils which further aggregate to different levels to form the fibre. Intermolecular hydrogen bonding at various levels, especially at the elementary level, is the major binding force that one need to overcome to reverse engineer these fibres

Abstract:

The unique feature of the seed of tetraploid cotton (Gossypium hirsutum and Gossypium barbadense) is that about 30% of the seed coat epidermal cells develop into cellulose-enriched fibres, while the embryos synthesize oils and proteins. Hence, both the maternal and filial tissues of the cotton seed are of significant economic value. After initiation from the ovule epidermis at or just before anthesis, the single-celled fibres elongate to 2.5–6.0 cm long in the tetraploid species before they switch to intensive secondary cell wall cellulose synthesis. Thus, apart from its agronomic importance,

We present a combined experimental and theoretical investigation of the dynamics of liquid imbibition through paper. The Washburn equation is widely used to describe the dynamics of capillary flow through paper, but this classical model has limited accuracy, which often makes it difficult to use in developing analytic systems such as paper-based microfluidic devices. We here report that the internal cavity of the cellulose fibres composing paper is significantly responsible for the limited accuracy of the Washburn equation.

Eco-friendly composites can be prepared by substituting man-made synthetic fibres with various types of cellulosic fibres. Sugar palm-derived nanocrystalline cellulose is a potential substitute. The most important factor in determining a good nanofiller reinforcement agent that can be used in composites is the character of the nanofiller itself, which is affected during a preliminary treatment. Thus, to gain better nanofiller properties, the delignification (NaClO2 and CH3COOH) and mercerization (NaOH) treatments must be optimized.
