What is the name of the process by which the center crease is semi-permanently removed?

Among all types of bottoms, the presence or absence of a center crease is one of the most important points when wearing slacks. Slacks with a center crease running in a straight line to the hem give a sharp and neat impression of the leg line and create a dressy and tense mood. However, depending on the fabric, the center crease may disappear after just one day of wear, requiring the trouble of ironing and sending them to the cleaners each time. Did you know that there is a “semi-permanent center crease treatment” that was developed to solve this center crease problem?

The name of the process that makes it difficult to remove the center crease is called “Permanent Pressing”! Reference when looking for slacks that can be worn easily

The name of the process that semi-permanently prevents the center crease from being removed is ” Permanent Press Processing. It is also called PP processing for short, and is used for shirts and skirts. This is a process in which the fabric is infiltrated with resin and pressed at high temperature after sewing to fix the shape. It is a convenient process that improves functionality, but its drawback is that it can only be applied to fabrics that do not contain polyester or other chemical fibers. Many products emphasize functionality by daring to increase the proportion of polyester in their fabrics, and push the appeal of center creases that cannot be removed semi-permanently or washable fabrics.

Of course, there is also the option of adopting slacks that emphasize practicality and specialize in functionality, but if you are also concerned about quality, it is a good idea to pay attention to slacks made of a hybrid fabric that mixes wool and polyester materials. The thermoplasticity and luxurious look of wool, combined with a permanent press finish, make these slacks a perfect match. Currently, most center-crease slacks made of fabrics with synthetic fibers from various brands and manufacturers seem to have a permanent press finish, but if you are concerned, we recommend that you choose items officially promoted by the brand. We hope you will take this into consideration when purchasing new slacks.
