The design should be based on the user's operating conditions, reasonable selection of materials, and a reasonable ratio. The anti-aging ability of plastic products under sunlight exposure is a question that is more concerned at present, but in addition, the broken wire of the ton bag is also a very serious situation, and the ton bag will be broken in the future.
1. The impact of low ambient temperature on flat wire breakage is not as sensitive as temperature. Generally, when the temperature is below 5°C, the flat wire of the ton bag is obviously brittle, and the probability of wire breakage increases significantly. When the temperature is below 10°C, brittle fracture may occur. When the relative humidity is below 50%, it is easy to break the wire. However, the ambient temperature is low and the relative humidity is low, and the wire is easy to break.
2. The strength of individual warp yarns is low. The reason why the warp yarn strength of individual ton bags is low may be that the surface or both ends of the spindle are scratched by hard tools during the transportation and turnover process, and there are large impurities and unmelted mother in the flat yarn fiber structure. Materials or crystal points, etc. Except for recycled materials, because individual flat yarns are too thin or too narrow, the warp will generally not be broken.
3. Flat yarn is fluffed. During the weaving process, the fluffed flat yarn of the ton bag starts to split when it passes through various threading holes and brown silk holes. Broken wires occur frequently.
4. Slub yarn and defective yarn, large slub yarn and wide flat slub yarn are difficult to pass through the brown fiber hole and are pulled off. The slub yarn itself has not been drawn, and the strength is low. If the hole is slightly blocked, the wire may break.
