Cotton morphology and mechanism of fibre tension was assessed by making use of light microscopy. In essence, a solution was prepared consisting of ZnCl2 (100 g), ki (32 g), water (34 ml) and I2(TILL SATURETION). This solution was used asa swelling agent for cotton during microscopic examination. It was found that the primary wall takes a spiral shape, a spherical shape, or combination of both whereas the secondary wall appears as beads. The shape and size of both primary and secondary wall depend upon the history of the fibre before swelling. When this fibre is subjected to the tensile load, the initial spiral is straightened upon increasing the load, Futher increase in the load causes breakage of straightend spiral (primary wall). There after the secondary wall has to stand the load alone till the latter is sufficient enough to break the secondary wall. |
