Development History Of Tarpaulin

Since the 1950s, truck tarpaulins and tarpaulin circles have existed and played an important role in China's railway transportation. Before 1977, the railway had been using the aluminum soap-resistant cotton canvas that was lagging behind in the 1930s to make truck tarpaulins, which not only consumed a lot of fine cotton, but also had poor waterproofing technology and poor waterproof performance every year. Re-waterproof. Since the tarpaulin is made of cotton canvas, it is not fireproof and is prone to mildew. Therefore, the station must be vacated and the workers should be specially aired before being put into storage. This also brings a lot of use to the tarpaulin. inconvenient.

    Later, silicone-treated vinylon canvas was tried as a tarpaulin. Although the tarpaulin is not easy to be mildew, it saves unnecessary trouble, but it is not fireproof, and its waterproof effect is not satisfactory, and a wet damage accident sometimes occurs.

After 1985, the trucks used Omron coated tarpaulins. Because the tarpaulin and tarpaulin ring have good versatility (waterproof, mildewproof, flame retardant, cold resistant, chemical resistant, etc.), it better meets the needs of railway transportation safety. In 1993, due to changes in the market for tarpaulin raw materials, the vinylon coated tarpaulin was changed to polyester coated tarpaulin and tarpaulin. In addition to the characteristics of the original vinylon coated tarpaulin, the polyester coated tarpaulin 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 greatly affects the performance of the final product. The tarpaulin base fabric is usually made of polyester, and there are also a small number of cotton, polyester, nylon, nylon and glass fiber products. Polyester is widely used in base fabrics due to its high strength, durability, good tensile properties and moderate price. Polytetrafluoroethylene fiber, carbon fiber, etc. have excellent performance, but a large number of applications are too expensive and are often used for special purposes. The new PVC cover material based on polyester industrial fabrics has gradually replaced the traditional tarpaulin of cotton, vinylon and polyester staple fiber, which has become the mainstream of development in the world today.
