[Case Study] Solved the issue of a hard texture!

Hair implantation into innerwear that directly touches the skin.

I received a request to use flocking on the belt part of women's lingerie bras to make it softer to the touch. Typically, binders (adhesives) contain formaldehyde, but since this would be used on parts that come into direct contact with the skin, it was necessary to reduce the content to less than one-tenth for safety reasons. Therefore, I started the development of the binder. This job was a request from the United States, so to carefully assess the impact on the skin, I conducted a patch test on 100 individuals in the U.S. (applying small pieces to the skin for a certain period to investigate any effects). I often thought along the way that it might not work out as I hoped, as the results were not coming as expected. However, by continuing to challenge myself without giving up, I was able to confirm safety successfully, and in the end, I received the official order contract! This was a significant project that took a year and a half from the initial request to the final order. Due to the many difficulties, I was able to build a very deep trust relationship with the dyeing factories, trading companies, and buyers involved in this work.
