of upstream and downstream related products
of polyester staple fiber Polyester staple fiber is an important raw material for chemical production, which is widely used in textiles, clothing, non-woven fabrics and other fields. Its upstream and downstream related products are numerous, forming a complete industrial chain. This article will detail the upstream and downstream associated products of polyester staple fiber.

1. upstream related products

1. Petroleum

The raw material of polyester staple fiber is polyester chips, and the raw materials of polyester chips are PTA and MEG, both of which come from petroleum. Therefore, the fluctuation of oil price has a direct impact on the cost of polyester staple fiber.

2. PTA

PTA is one of the main raw materials of polyester staple fiber, accounting for more than 60% of the production cost of polyester staple fiber. The price fluctuation of PTA has a great influence on the production cost of polyester staple fiber.

3. MEG

MEG is another main raw material of polyester staple fiber, which is used to produce polyester chips. The price fluctuation of MEG will also affect the production cost of polyester staple fiber.

2. Downstream Related Products

1. Textile

Polyester staple fiber is one of the important raw materials for textiles, which can be used to produce various clothing, home textiles, industrial textiles, etc. Therefore, the downstream related products of polyester staple fiber include all kinds of textiles.

2. Non-woven

non-woven fabric is a non-woven material, which is widely used in medical and health, filtration, packaging and other fields. Polyester staple fiber is one of the important raw materials of non-woven fabrics. Therefore, the downstream related products of polyester staple fiber also include non-woven fabrics.

In summary, there are many upstream and downstream related products of polyester staple fiber, including upstream raw materials such as petroleum, PTA, MEG and downstream products such as textiles and non-woven fabrics. The production and use of polyester staple fiber is of great significance to the operation and development of the entire industrial chain.
