There are at least 1000 types of plant that bear usable fibers [1]. Natural plant fibres are easily obtained in many tropical parts and are available throughout the world. Today these fibres are considered as environment friendly materials owing to their biodegradability and renewable properties [2]. Natural fibres have applications in fields of textile, paper manufacturing, and bioenergy indus...

Nowadays there are no doubts about the positive impact that fruits and vegetables have on human health. Plant fibres (i.e. non-digestible carbohydrates) are widely present in daily food, such as soups, dressings and sauces. On the other hand, agricultural (non-wood) by-products have a low economical value. However, those residues are frequently important sources of fibres so an important resear...

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...

Plant fibres-cells with important mechanical functions and a widely used raw material-are usually identified in microscopic sections only after reaching a significant length or after developing a thickened cell wall. We characterized the early developmental stages of hemp (Cannabis sativa) stem phloem fibres, both primary (originating from the procambium) and secondary (originating in the cambi...

Oriented fibres in the intercisternal regions of plant dictyosomes are usually associated with flattened portions of cisternae. In outer cap cells of maize roots, however, the intercisternal fibres are associated mainly with unique secretory vesicles which are elongate or kidney-shaped during their formative stages. Fibres are oriented parallel with the long axes of the vesicles even at early s...

Plant fibres are helically twisted cellulosic materials that bonded together by lignin and hemicellulose matrices.

The main objective of the present paper is to report on the concentration of silicon carbide (SiC) fibres, crystalline silica and respirable dust in a Canadian SiC production plant and to compare the results with earlier investigations. The second objective is to tentatively explain the differences in concentration of the fibrogenic substances between different countries. The assessment of SiC ...

An estimate of the extent of conversion of plant nitrogen to microbial nitrogen in the rumen of sheep fed on wheaten hay was reported in an earlier communication (Gray & Pilgrim, 1953). The basis of separation of plant from microbial material was simply the filtration of the rumen contents through muslin with subsequent limited washing of the fibrous plant residues to free them from the remaini...

Las fibras vegetales, que se basan en estructuras ligno-celulósicas, están dispuestas como compuestos biomiméticos, el sentido de incluyen una relación compleja entre matriz más blanda y un refuerzo duro a través interfaz, con uso continuo porosidades arreglos celulares. Sin embargo, las pueden extraer diferentes partes la planta según especie, práctica del tallo, corteza, fruto, hoja o incluso...
