Softening Process in the Manufacturing of Jute
In the manufacturing of jute, the jute fiber must first be softened. The softening machine consists of many pairs of fluted or corrugated rollers arranged in horizontal succession and driven with a reciprocating motion. The jute as it passes through may receive a sprinkling of oil ad water from automatic apparatus attached to the machine overhead, or it may be arranged in the layers and sprayed with oil after emerging from the softener, a process known as batching. In either case, the material is then allowed to lie a certain time in bulk, to permit of the fiber being thoroughly permeated with the oil.
