The development history of tarpaulin
From the 1950s, goods Car tarpaulins and tarpaulin loops have already existed and play an important role in my country’s railway transportation. Before 1977, the railway had been using cotton canvas waterproofed by the aluminum soap method in the 1930s to make truck tarpaulins. Not only did it consume a lot of fine cotton, but this waterproofing process was backward and its waterproof performance was also poor. Every year Re-waterproof. Because the tarpaulin is made of cotton canvas, it is not fireproof and is prone to mold and mildew. Therefore, the station must clear space and have workers dry it before it can be sorted and stored in the warehouse. This also brings a lot of trouble to the use of the tarpaulin. inconvenient.
Later, silicone-treated vinylon canvas was tried as a truck tarpaulin. . Although this tarpaulin is not prone to mildew and rot and saves unnecessary trouble, it is not fireproof and its waterproof effect is not ideal, so wet damage accidents occur from time to time.
After 1985, vinylon-coated tarpaulins were fully used on trucks. Since this type of tarpaulin and tarpaulin loops have good multi-functionality (waterproof, mildew-proof, flame-retardant, cold-resistant, chemical-resistant, etc.), they can better meet the needs of railway transportation safety. Due to changes in the tarpaulin raw material market, in 1993 the vinylon-coated tarpaulin was changed to polyester plastic-coated tarpaulin and tarpaulin rings. In addition to the characteristics of the original vinylon plastic-coated tarpaulin, the polyester plastic-coated tarpaulin also has the advantages of high strength, good aging resistance and low-temperature performance, thin, light, and soft, and is a good replacement product.
The base fabric is the skeleton of the tarpaulin, and its performance affects the performance of the final product to a great extent. The base fabric of tarpaulin products is usually made of polyester, but there are also a small number of cotton, polyester-cotton, nylon, eyeliner and fiberglass products. Polyester is widely used in base fabric products due to its high strength, durability, good tensile properties and affordable price. Polytetrafluoroethylene fiber, carbon fiber, etc. have excellent properties, but are too expensive for large-scale applications and are often used for special purposes. PVC new tarpaulin materials based on polyester industrial fabrics have gradually replaced traditional cotton, vinylon, and polyester staple fiber tarpaulins and have become the mainstream of today’s development.
