Polypropylene PP particle drawing is used to extrude, stretch, shape, and roll up the warp and weft threads according to the standard width, denier number, and thickness through a high-speed drawing machine. After passing the quality inspection, the circular weaving workshop will carry out wire arrangement, threading, installation of corresponding size rings, debugging, grinding, and winding to complete the initial production steps of the base fabric. After the visual and dust removal equipment inspection of the fabric is completed through quality inspection again, the wrapping packaging and outer packaging are wrapped and stored in the warehouse.

The anti-static container bag base fabric is also made of Type A weaving links. However, the breakdown voltage of the woven fabric of TypeB bags cannot exceed 4KV. This means that the Type B container bag will not generate propagating brush discharge. This is an important classification, which means that few discharges that can be generated on container bags are low energy brush discharges. If the propagation type brush discharge can be excluded, and the super energy of the brush discharge is 4mJ, it is reasonable to believe that this type of container bag is safe for the combustible gas environment where the ultra small ignition energy does not exceed 4mJ.

The Type C anti-static container bag base fabric is designed for sensitive and flammable environments, including flammable hydrocarbon solvent vapor environments. This type of container bag base fabric is made of conductive fabric or woven fabric coated with conductive/anti electric coating. Conductive cloth is actually a woven fabric interwoven with conductive fibers/flat wires. In some designs, the conductive wires are parallel with a spacing of 20mm. A higher demand design is to weave conductive wires into a network shape, with the wires intersecting vertically.

The base fabric of Type D conductive container bags should have anti-static or electrostatic dissipation characteristics, without the need for grounding, and is usually synthesized using nylon fiber yarn. Most of the Type D container bags on the market today are made by interweaving thin semi conductive wires into woven fabric. Unlike the design of Type C container bags, these semi conducting wires, although parallel in meridional direction, are not cross-linked. Conductive wire is usually composed of conductive metal coating or conductive metal wire. This type of container bag will have an electrostatic elimination coating, so we usually refer to it as a conductive container bag.

Its processing technology is similar to Type A, with a folding process followed by three layers during the wire drawing process, followed by other stages of production. It mainly solves the problem of high weft tension damage in the ordinary weaving process, which is more than 25%, and the damage rate of the three fold is less than 15%. This increases the tension and makes the irregular squeezing of the fabric weaving become a regular arrangement, improves the flatness of the fabric, and makes the overall effect of the container bag more recognized by customers.
