The invention relates to manufacture method of spinnable jute fiber, manufacture system of jute yarn, jute yarn that is used for dyeing and weaving the clothes. Manufacture method of jute fiber includes the following procedures: Wash out jute material to improve its absorptivity and fibrillation action, bleach the washed jute to improve its fibrillation action and whiteness, go through reductive treatment and neutralization, apply surface softener to jute for 30 to 60 minutes, dewater and dry it, loosen and separate jute fiber, spray softener fluid on jute fiber, boil down jute fiber in steam room, it hence gets soft, flexible and spinnable fine jute fiber. Above spinning systems include mixing, feeding, carding, drawing, yarn conditioning, free choice of winding. Dyeing systems of jute yarn include beaming, dyeing, sizing and drying.
Winch dyeing method that uses indigo derivatives，It opens winch dyeing method that dyes denim into popular blue. It twists, repeatedly immerses it into dye vat of reductive indigo derivative water solution that can have air oxidization, extrudes dye bath, exposes and air oxidizes reductive indigo derivative from yarn, further oxidizes reductive indigo derivative that is not completely oxidized in oxidation tank which contains chemical oxidant such as sodium perborate etc. |
