Big bags are a kind of woven bags, which are often used in container transportation at the wharf. Let's take a look at the production details of the ton bag and the problems that need attention.
1. Check the material selection of the base cloth
First clarify the weight of the loaded goods when designing the ton bag. Determine the volume according to the specific gravity of the packaged materials. It also depends on whether the loaded material is a sharp and hard block material. If it is designed, the base fabric should be thicker, on the contrary, it can be thinner.
2. Close the material selection of the sling
Sling material selection is very important. There are relevant regulations that clearly stipulate a safety factor of 16. In actual design, in design. One is to consider the loss of the strength of the sling during the sewing process; the other is to consider the hoisting method.
3. Improve monofilament strength
It is necessary to increase the tensile strength of the flat yarn. The relative strength of the flat wire should reach more than 0.4Ntex, and the strength of the base fabric must be ensured. Elongation 15-30. In the actual production and processing process, the amount of filler masterbatch needs to be strictly controlled, generally around 2%. If too much masterbatch is added, or recycled materials are added, the strength of the base fabric will decrease. Therefore, we must strictly control the quality of raw materials, and select wire drawing raw materials produced by regular manufacturers whose melt index reaches the national standard.
In fact, no matter what kind of product it is, it is necessary to strictly control the quality of the product during production. Only in this way can it spread its reputation and secure its market share. Therefore, for the production technology of ton bags, it is not only necessary to increase the production speed, but also to strictly control the quality, so that the ton bags can meet the qualified requirements.
