Polyester industrial yarn is an important raw material for chemical production and is widely used in various fields. Its upstream and downstream related products are numerous, mainly related to petroleum, petrochemical, coal chemical industry, basic chemical raw materials, chemical fiber, textile, printing and dyeing, clothing and other fields. The following will detail the upstream and downstream associated products of polyester industrial yarn.

Upstream Related Products:

1. Petroleum: The raw materials for the production of polyester industrial yarn mainly come from petroleum. After cracking and separation of petroleum, the raw materials needed for polyester industrial yarn-benzene, xylene, etc. can be obtained.
2. coal chemical industry: coal chemical industry can also provide raw materials for the production of polyester industrial silk, such as coal to benzene.
3. basic chemical raw materials: the production of polyester industrial yarn also needs some basic chemical raw materials, such as acetic acid, ethylene glycol and so on.

downstream related products:

1. chemical fiber: polyester industrial yarn is one of the important raw materials in the chemical fiber industry, which can be used to produce polyester filament, polyester staple fiber, etc. These chemical fiber products are widely used in clothing, home textiles, industrial textiles and other fields.
2. Textile: Polyester industrial yarn can be used in the textile field to produce various specifications of canvas, filter cloth, conveyor belt and other textiles.
3. Printing and dyeing: Polyester industrial silk needs to be printed and dyed to obtain various colors and patterns. Printing and dyeing process need to use a variety of dyes, auxiliaries and other chemicals.
4. Clothing: Polyester industrial yarn can be used to produce all kinds of clothing, such as sportswear, outdoor clothing, etc. Because of its excellent wear resistance, wrinkle resistance, shape retention and other characteristics, it is well received by consumers.

In short, there are many upstream and downstream related products of polyester industrial yarn, involving a wide range of fields. Its production and use are of great significance for promoting economic development and improving people's lives.
