Thermal behaviour of linen and chemically treated linen fibres

Thermal degradation of flax and jute fibers

“…1(b)]. Confirmed with the published data for linen fibers, 21 a slightly improved thermal stability of jute and linen fibers can be reached due to alkali treatment.…”

Improvement of the graft and dyeability of linen by DBD treatment in ambient air

“…It can be seen that the dyeability improves with the increase of grafting efficiency and this indicates that grafting efficiency is the key for the improvement of dyeability. The reasons may come from the following two aspects: the main component of linen is cellulose (Sefain et al, 1995) and cellulose contains many hydroxyl sites (Tindall et al, 2002). The positive electrical characteristic of carboxyl of grafted AAc in alkaline solution will attract more active dye to reach the surface of linen to form covalent chemical bonds with hydroxyl sites (Tam et al, 1997).…”

Effect of Lignin on the Heat and Light Resistance of Lignocellulosic Fibers

“…All the known natural cellulose fibers, except cotton and kapok, are multicellular with several single cells (ultimates) held together to form a fiber bundle. Lignin is the major binding material holding the single cells together and plays a major role in determining the structure, properties, processability and end use applications of lignocellulosic fibers 1–3. The amount of lignin in the fibers varies from as low as 2–3% in linen to as high as 40–45% in coir.…”

“…The presence of lignin imparts a natural color making it difficult to bleach the fibers to good whiteness. Lignin also makes the fibers stiff and harsh to handle and accelerates the degradation of fibers when they are exposed to heat and light 1–3. However, removing all the lignin from the fiber bundles would result in single cells that are too short to be used for textiles and other high quality fibrous applications.…”

“…The effect of heat and light on the properties of cotton, lignocellulosic and protein fibers has been extensively investigated 1, 3, 17–21. Untreated and alkali treated flax and jute fibers were found not to be affected by heat below 170 °C, whereas temperatures above 170 °C were found to drastically affect the tenacity and degree of polymerization of cellulose in the fibers.…”
