The difference between polyvinyl alcohol fiber and polyester fiber

There are differences between polyvinyl alcohol(PVA) fiber and polyester fiber in chemical structure, physical properties and application fields.

First, the chemical structure of polyvinyl alcohol fiber and polyester fiber is different

PVA fiber contains a large number of hydroxyl (-OH) functional groups in its molecular structure, so it has good hydrophilicity and solubility. In the molecular structure of polyester fiber, it mainly contains ester group (-COO-) function group, so it has good water resistance and durability.

Second, the physical properties of PVA fiber and polyester fiber are different
The tensile strength and modulus of polyvinyl alcohol fiber are low, but it has better softness and bending property. Polyester fibers have higher strength and modulus, but are relatively hard and easy to break. In terms of heat resistance, polyester fiber shows good performance and can withstand high temperature processing; The polyvinyl alcohol fiber is easy to melt and decompose at high temperatures.

Third, the application fields of polyvinyl alcohol fiber and polyester fiber are different

Due to the different characteristics of polyvinyl alcohol fiber and polyester fiber, they have their own application advantages in different fields. Polyvinyl alcohol fiber is often used in textile, paper processing, plastic film and other fields, and can also be made into waterproof, moisture-proof, anti-static and other functional fibers. The polyester fiber is often used in the production of clothing, fabrics, ropes and other products with high strength and wear resistance, and is also often used in the production of various plastic products.

In short, there are significant differences between polyvinyl alcohol fiber and polyester fiber in their respective chemical structures, physical properties and application fields. Therefore, in actual production and application, product designers and producers need to choose suitable materials according to different needs.
