In general, Felt is used for clothes, hats, gloves, bags, tables, etc. by using a property that wool fibers are entangled with each other to harden the wool to a certain thickness. And as a paper machine, there is a dictionary meaning that it refers to a nonwoven fabric made like a paper sheet. Recently, industrially used felt means that the fibers are arranged in parallel or in an opposite direction without going through a woven process, and are bonded with a synthetic resin adhesive. Cotton and viscose rayon were mainly used as raw materials, but recently, synthetic fibers such as nylon were also used.

There are immersion and dry processing methods, also known as papermaking method, and the fibers are soaked in a plastic glue bucket and dried and heat treated, similar to paper.

Drying is the drying of fibers made of thin cotton with synthetic resins.

The characteristic of the felt is that the fibers are entangled so that there is no lateral and lateral direction, and the edges are not loosened, so they are used for various purposes.
