identificar el lyocell. Birla Excel, la fibra de lyocell de marca de Birla Cellulose, es ecológica, se obtiene de recursos renovables y se fabrica mediante un proceso de ciclo cerrado. Se biodegrada en seis semanas, por lo que es fácil de eliminar sin generar más residuos en los ...
On a étudié l'effet de la longueur des fibres sur les propriétés mécaniques et physiques des ciments renforcés de fibres de cellulose. L'augmentation de la longueur de la fibre renforçante améliore la résistance à la flexion, l'énergie de rupture statique, la résistance au choc...
Composite contenant de la cellulose, a savoir 20 a 99 % de cellulose fine et 1 a 80 % d'au moins une fibre alimentaire soluble dans l'eau presentant une viscosite basse et selectionnee dans le groupe constitue par (1) des produits de decomposition de galactomannane, (2) de la dex...
These figures explain the existing interest in trying to recover this fibre and avoid the pollution which results by its rejection. SUMMARY OF THE INVENTION The subject of the invention is a process and a device for resolving these problems. ...
[0030] cellulose can be obtained by treating the fabrics with a compound that evolves formaldehyde when heated followed by treatment with a solution containing 2 to 61 alkali and a glycol softener. In practice however this method does not give very satisfactory results when applied ...
The lowering of the cation exchange capacity and of the pectin content of the cell walls during growth results principally from increased cellulose deposition in the fibre cells. The changes in the cation exchange capacity and in the percentage of cell wall show that when cel...

Yields of structural components such as neutral-detergent fibre, acid-detergent fibre and acid-detergent cellulose, followed a pattern similar to that of crude protein. There therefore appears to be a flexible harvest period ranging from flowering until the beginning of seed filling (seeds with 380...
