ABSTRACT
Jute plant retting is a preferential rotting process in which jute plants are submerged in water and subsequently jute fibers are extracted out by decomposing the cellular tissues and pectin surrounding the fiber bundles through the joint action of water and aquatic/soil microorganisms. Due to the shortage of water during retting period of jute, all crops cannot be stacked at a time and therefore farmers are often compelled to harvest over-matured plants and use the same water body repeatedly for retting. This generates inferior quality of fiber. Traditional retting is also labor intensive and not environment friendly and takes longer time to ret. A feasibility study has been undertaken for dry retting of jute plants on land under water limiting condition using a defined microbial consortium. Field trials of dry retting of jute plants carried out at farmer’s level have shown promising results wherein jute plant retting can be achieved in shorter time without submerging jute plants in water body. Quality of jute fibers obtained from such dry retting process is comparable to the conventionally retted jute process.
摘要
黄麻植物脱胶是一种优先腐烂过程,黄麻植物浸没在水中,随后通过水和水生/土壤微生物的共同作用分解纤维束周围的细胞组织和果胶,提取出黄麻纤维. 由于黄麻脱胶期间缺水.无法一次堆放所有作物,因此农民往往被迫收获过熟的作物,并重复使用同一水体进行脱胶. 这会产生劣质纤维. 传统的脱胶也是劳动密集型的,不环保,而且脱胶时间较长. 利用确定的微生物群落,对陆地上黄麻植物在水分限制条件下的干法脱胶进行了可行性研究. 在农民一级进行的黄麻植物干法脱胶的田间试验表明,黄麻植物脱胶可以在较短的时间内实现,而不会将黄麻植物浸没在水体中. 从这种干法脱胶工艺中获得的黄麻纤维质量与传统的脱胶黄麻工艺相当.
HIGHLIGHTS
A feasibility study has been undertaken for dry retting of jute plants on land under water limiting condition using a defined microbial consortium to replace conventional jute retting practice in this global water scarcity scenario.
A novel technique Faster retting of jute plants with low water foot print
Through dry retting, average quality of jute fibers (TD3 as per IS 271: 2020) has been obtained with minimal water requirement and also in shorter retting duration (12–14 days).
