retting is a process to obtain fibre of

51.254.248.9. This binding must be degraded to obtain useful fibres for strong composites. Ind Crops Prod 45:160–169, Frollini E, Bartolucci N, Sisti L, Celli A (2015) Biocomposites based on poly(butylene succinate) and curaua: mechanical and morphological properties. To make fabric, we have to first convert the cotton fibres into yarns by which of the following process? To obtain the load solely acting on fibre bundles, ... Optimization of the retting process to permit improved fibre separation whilst maintaining fibre strength would be worth future investigation as it has potential applications in current industrial practices. Environ Microbiol 5:730–736, Thomas S, Paul SA, Pothan LA, Deepa B (2011) Natural fibres: structure, properties and applications. The process comprises treating the fibrous plants with at least one SPS-ase enzyme and preferably a mixture of enzymes comprising β-glucanase, pectinase and SPS-ase.

Appl Biochem Biotechnol 142:276–290, Cong R, Dong W (2007) Structure and property of mulberry fiber. The stalk bundles are weighted down, usually with stones or wood, for about 8 to 14 days, depending upon water … Not only is this labor-intensive, farmers and/or workers must be knowledge-able about fiber quality. Following retting, a sequence of processes to remove the fibres from the woody stalks is carried out first by breaking them and then scraping or scutching them off which is done by beating with blunt wooden or metal blades either by hand or mechanically. Retting time must be carefully judged;… A bit like making sauerkraut - retting is a controlled rotting and it can be done several different ways.
