Question

14. Which part of the flax plant yields fabric?​

Answer 1

Flax

Flax fiber is extracted from the bast or skin of the stem of flax plant. Flax fibers are arranged in the form of thin filaments, grouped in longitudinal slender bundles distributed circularly around a central wooden cylinder. These bundles are fully embedded into an intermediary holding tissue binding them outwardly to the protective outer skin and inwardly to the inner supporting wooden cylinder. The holding tissue is made up entirely of dynamic cells, having semi-permeable membranes. The wooden cylinder, the fibers and the outer skin, in contrast, are totally made up of fixed static cells, having normal permeable membranes. Flax fiber is soft, lustrous and flexible, stronger than cotton fiber but less elastic. The extraction of the fiber occurs in three stages. First the cortex or bark is removed (decortication). The cortex is then scraped to remove most of the outer bark, the parenchyma in the bast layer and some of the gums and pectins. Finally, the residual cortex material is washed, dried and degummed to extract the spinnable fiber.10 The best grades of flax are used for linen fabrics such as damasks, lace and sheeting. Coarser grades are used for the manufacture of twine and rope. Flax fiber is also a raw material for the high quality paper industry for use in printed banknotes and rolling paper for cigarettes.
