Use of Unconventional Fibres for the Manufacture of Fabrics, Sitra Coimbatore, India. Technical Report: Chemical Modification of Pineapple Leaf Fibres

摘要

The objective is to plan and conduct experiments on chemical modification and enzymatic degumming of pineapple leaf fibers (PALF) with a view to producing finer fibers, and to advise on dyeing and finishing of PALF and other leaf fibers. Because of the variability of PALF, care must be taken to ensure thorough randomization of the fibers in experimental studies. Scouring with a dilute alkali and a sequestrant, followed by peroxide bleaching, may significantly improve fiber quality prior to spinning. Mechanical separation of the fibers should not be neglected. Long fiber combing equipment similar to a flax 'hackling' machine may be effective either before or after the chemical treatment. Suitable industrial cooperation for enzyme studies has been established. A program of work on the dyeing of PALF has been drawn up.
