LINEN: fibres with regular contours and marked transversal striations
COTTON: fibres with smooth contours, with frequent
JUTA: fibres with little regular contours and some transversal striations
CONCLUSIONS
Each fibre is characterized by a particular aspect that allows it to be distinguished from the others by microscopic analysis. Wool is the most easily recognizable fibre due to the presence of flakes which are flat and partially overlapped and all oriented towards the tip of the fibre. Nylon synthetic fibre of polyamide nature differs from silk, natural protein fibres due to its thickness and the presence of spots.
The natural vegetable fiber cotton is distinguished from the others by the frequent windings and by the not always visible presence of the lumen (central channel that occupies the space of the cell nucleus). Finally, jute and linen very similar fibers differ mainly due to the quantity of transversal striations that correspond to the point of contact between a tubular cell and the other of the phloem.
MORPHOLOGY OF FIBRES
Here below there is The following fibre descriptions of the main features, the chemistry formula of their structure and graphic representation of their longitudinal and cross section, so as they appear through the microscope help to specify the type; during the combustion all the organic compounds produce H2O and CO2 (water and carbon dioxide). Use formula is that one of the component plus NCO2 + Y/2 H2O
