Film covered woven bag process Plastic Biansi production process is the raw materials and accessories mixed with the extruder melt it out into a film, the film after cooling, divided into a strip of silk (blank wire), and then stretched Orientation to produce flat yarn, and finally these flat yarn wound on the bobbin, made of spindles to send a knitting process weaving production process.
The process of producing PP split yarn is basically the same as the process of producing flat yarn, and only after it is divided into the strand (blank), an additional process of meshing is added.
The main raw material for the production of flat or split-end industrial yarn is polypropylene (PP), sometimes also HDPE, LLDPE or blends thereof.
Auxiliary raw materials to produce flat yarns are mainly masterbatch (calcium filler), colorants (masterbatch) and other modifiers, such as antioxidants, lubricants and so on.
The main equipment for producing flat yarn or split-film industrial yarn is wire drawing machine, winding machine, auxiliary equipment is a mixer, waste recycling equipment and so on.
Flat or PP split yarn production process is the most critical and most complex process in laminating woven bags. Its main technical indexes are: temperature and pressure control of extruder, cooling, stretching, heat treatment (setting) Temperature control, flat wire draft ratio, relative breaking force, the control of elongation at break, output, energy consumption, output ratio and other control.
