Ton bag is a flexible transport packaging container. It has the advantages of being moisture-proof, dust-proof, radiation resistant, firm safety, and has sufficient strength in structure. Because the loading and unloading of tons of bags are very convenient, the loading and unloading efficiency has been significantly improved, and it has developed rapidly in recent years. Ton bags are generally made of polyester fibers such as polypropylene and polyethylene. Can be widely used in chemicals, building materials, plastics, mineral products, and other types of powder, granular, and block goods packaging, and is the ideal supplier for warehousing, transportation, and other industries. So what details should we pay attention to when sewing ton bags?
1, number of strands, fracture strength, twist, twist direction. Number of strands: Each strand is made of several strands, usually 2-12 strands;
2, plastic knitting with cotton thread and polyester thread technical trend, plastic knitting sewing useful cotton sewing thread according to the national standard GB/T6835-1997 and polyester sewing thread national standard GB/T6834-1997.
3, the thread density (tex) and the British count (Ne), the thread density is a measure of the quality standard on the unit length of tall things, on the sewing thread can be regarded as the thickness of the thread. As for polyester thread and cotton thread, because the polyester thread is heavier than cotton thread, polyester thread is thinner than cotton thread when drawing a line density, symmetrical strand thread, and viscosity conditions, how to square polyester thread.
