Why is 30D Polyester Fusible Interlining anti-wrinkle and anti-shrink?

The reason why 30D Polyester Fusible Interlining has anti-wrinkle and anti-shrink properties is mainly due to its unique fiber structure and material characteristics. The following is a detailed explanation of why 30D Polyester Fusible Interlining has anti-wrinkle and anti-shrink properties:

Molecular structure and chemical properties：Polyester is a kind of synthetic fiber, whose molecular structure makes it less absorbent when in contact with water. Compared to the fiber, the gap between the molecules is smaller, so in the wet polyester fiber, the molecular structure is more compact, making the fabric more stable and not easy to shrink.

High elasticity and shape memory characteristics: 30D Polyester Fusible Interlining lining has high elasticity, and can quickly recover its original shape after being subjected to stress. Restore to the original state, reduce the wrinkles caused by the fabric due to use.

Heat resistance: polyester has good heat resistance, which means that 30D Polyester Fusible Interlining lining can also maintain a relatively stable shape in high temperature environments. Compared with some natural fibers, polyester does not easily shrink at high temperatures, so Reduce the shrinkage phenomenon caused by the fabric in high temperature.

Effects of manufacturing process: In the manufacturing process of 30D Polyester Fusible Interlining, some advanced finishing techniques are usually used, such as hot fixed shape and fixed shape processing. These processes can make the fiber maintain a more stable shape during the fabric forming process, so Increases the fabric's anti-wrinkle and anti-shrink properties.

Effect of fiber fineness: 30D shows the diameter of 30 fibers and the sum of 1 millimeter, therefore, compared to some coarser fibers, the fineness of polyester is smaller. This smaller fiber fineness makes the surface of the fabric more smooth. ，Reduce the friction between the fibers，Reduce the possibility of the fabric producing wrinkles。

The anti-wrinkle and anti-shrink properties of 30D Polyester Fusible Interlining are the result of the joint action of various factors such as its unique molecular structure, chemical properties, high elasticity, heat resistance and manufacturing technology. These characteristics make 30D Polyester Fusible Interlining In the application scenario, it can maintain a more stable shape, providing users with a more durable and easy-care fabric choice.
