The traditional methods for separating the long bast fibres are by dew and water retting. In double retting, a gentle process producing excellent fibre, the stalks are removed from the water before retting is completed, dried for several months, then retted again.

In a process called “breaking”, stalks are passed between fluted rollers to crush and break the hurd into small pieces, separating some of the fibre in the process. This chapter aims to provide a classification and an overview of the retting procedures that have been developed during years and are applied to extract mainly bast fibers. After retting, the straw is then put through three different mechanical processes.

Fibre Separation. Both methods require 14 to 28 days to degrade the pectic materials, hemicellulose, and lignin. The process of making fabric or cloth by arranging yarns at right angles to them, is called weaving.The process of making a fabric by interlocking loops of single yarn with knitting needles or machines, is called knitting. Retting time must be carefully judged;… Cite as. Retting time … The Health Star Rating System was established in 2014 as a preventative measure in slowing or reversing the rate of overweight Australians. The quality of the natural fibers is largely determined by the efficiency of the treatment process and can dramatically influence the properties of the final composites. Besides, enzymatic retting is claimed to have more environmentally friendly wastewater products, shorter retting period and controllable fiber biochemical components under mild incubation conditions. Processing of sustainable organic fibre starts with fibre extraction and yarn production followed by bleaching, dyeing, softening, printing and drying.

Chemical retting is more expensive and does not produce the superior quality fibre obtained from the biological retting process. cellulosic fiber or fiber bundles obtained from wood or agricultural plants through a retting process. The overall fiber extraction processes, applied to vegetable fibers, is called retting and consists in the separation of fiber bundles from the cuticularized epidermis and the woody core cells.
