Polyester curtain fabric has become the preferred curtain material for many homes and commercial spaces due to its outstanding physical properties. Among them, its ability to maintain strength similar to that in dry state in wet state is a highlight of polyester curtain fabric. This property is due to the unique chemical and physical structure of polyester fiber.

Polyester curtain fabric is made of polyester fiber, which is a synthetic fiber made by polycondensation and melt spinning of polyester compounds. The internal structure of polyester fiber is compact and stable, and the interaction between molecular chains is strong, which makes polyester fiber have high strength and elasticity. This structural characteristic allows polyester curtain fabric to exhibit outstanding mechanical properties in dry state.

However, when polyester curtain fabric is in wet state, many other fiber materials may experience a decrease in strength. But polyester curtain fabric can still maintain strength similar to that in dry state in wet state, which is mainly due to the hydrophobicity of polyester fiber.

The molecular structure of polyester fiber contains a large number of ester groups, which make the surface of polyester fiber have low surface tension, thus showing hydrophobicity. When polyester curtain fabric encounters moisture, it is difficult for moisture to penetrate into the fiber, but stays on the fiber surface to form a water film. This water film not only does not destroy the molecular structure inside the fiber, but can increase the friction and mutual support between the fibers, so that the polyester curtain fabric can still maintain a high strength in a wet state.

In addition, polyester fiber also has good chemical corrosion resistance and heat resistance. These properties enable polyester curtain fabric to maintain stable performance in a wet environment even if it encounters some chemicals or temperature changes, thereby maintaining its strength.

Combined with the above, it can be summarized that polyester curtain fabric can maintain a strength similar to that in a dry state in a wet state, mainly due to the unique chemical and physical structure of polyester fiber. This structure makes polyester fiber have high strength, high elasticity and hydrophobicity, and can maintain stable performance in a wet environment. Therefore, polyester curtain fabric not only has outstanding mechanical properties in a dry state, but also maintains its strength and aesthetics in a wet state, becoming an ideal choice for many consumers.
