The production process of woven bags is as follows: raw materials ->wire drawing ->weaving ->coating ->cutting ->printing ->sewing ->inner bag ->inspection ->sorting ->packaging ->warehousing.

In the above production processes, wire drawing, weaving, coating, etc. are the main processes that cause losses.

1. Wire drawing: This process is one of the processes that consume the production of plastic woven bags, and there are a total of 4 stages where losses occur:

(1) There are plastic sheets and blocks that do not form a film during melt extrusion;

(2) There are hard edges on both sides of the membrane when it is cooled and cut to pieces;

(3) The shaped single wire is sucked into the waste wire box when it is wound into the bobbin.

(4) The cost of replacing different standard types, colors, and cleaning filters each time.

2. Weaving: In this process, there are also relatively high costs, with a total of 3 processes incurring costs:

(1) The single filament bobbin rotates on the warp frame and needs to be arranged in an orderly manner, with the occurrence of filaments, floating filaments, and dirty filaments when threading jump bars and buckles;

(2) When the weft packaging enters the circular movement of the shuttle, there are occurrences of filaments, floating filaments, and dirty filaments;

(3) The cost of the single filament and single chip process for the front and rear extradition when replacing different types of woven fabrics with different widths and units each time.

3. Coating: The coating process is one of the processes with high unit consumption, and there are three small processes involved in the consumption:

(1) After coating a single piece of woven fabric, it is necessary to remove the burrs;

(2) When the raw material is extruded through melting, there is a high-temperature plastic melt material that does not form a film;

(3) The cost of replacing single and composite woven fabrics before and after each replacement of standard types with different door widths and unit weights.
