Rope washing machines

The line diagram of tight rope washing machine is given in Fig. 7-42. The machine 

In the slack rope washing machine (Fig. 7-43), the fabric rope is allowed to drop 

Another type, namely square beater washing machine is used mainly for washing printed goods. The beater revolves in a direction opposite to that of the cloth so that It receives a flapping motion which beats out loose particles adhering to the fabric. 

After rope washing, the fabric is passed through the rope squeezing machine

Raw stocks and yams in packages or in beams can be bleached only by the liquor circulating machines. Cotton yam in the form of hank can be bleached as a rope of cloth using pressure kiers, washing machines and hypochlorite bleaching pits. But the modem tendency is to bleach in a more efficient manner in dyeing machines in the form of beams (Fig. 7-3) and packages (Fig. 7-4). This machine... 

In the plastics recovery section, the polypropylene is separated from other plastics and products such as PVC separators, ebonite cases, labels, rope handles, etc., via a series of classifiers and hydro-cyclones. The polypropylene pieces or chips are cleaned, washed, and separated from any remaining paste and dust. Once the material has been shredded to smaller fragments, the plastic is a valuable by-product of battery recycling. Plastic cleaning and processing methods are so effective that heavy metal contamination in the final polypropylene product is very low. The final product can be used in household goods such as washing machines, vacuum cleaners, and dishwasher parts, or in products for the automotive industry [5].

For the production of sisal fibers, the freshly harvested leaves of the agave plant are pressed in machines to separate out the fibers. Subsequently, the separated fibers are washed, dried in the sun, bleached, and combed with rotating brushes. The sisal fiber is used in ropes, mats, carpets, packaging, and Ailing materials. 

The cut leaves are taken to a factory, where the fibers are extracted by machines (decorticater). This machine works mostly with large quantities of water, which are used to wash away the waste. After extraction, the fiber bundles are washed and dried in the sun or with drying machines, graded and further processed to threads, ropes and twine. In former times, s. fibers were mostly used for so-called binders for tying harvested temperate cereals into sheaves before stacking. This ended suddenly when combine ->harvesters replaced binders.
