Girls prefer plush toys. If you observe carefully, you will find that most of the plush toys are made of wool felt. Many people don’t know much about wool felt, let alone it. The principle and production process of wool felt, so what is the principle of wool felt? What is the production process like? Let’s introduce it below.

The principle of wool felt is very simple, which is the result of felting of wool. Generally, the principle of wool felt is divided into two types: wet felt and dry felt. The specific production process is as follows:

1. Wet felt: Wool will feel particularly soft, comfortable and delicate to the touch, because there are a large number of scale tissues on the surface of the wool. These tissues are generally invisible to the naked eye and can only be seen when encountering them. It will not open until it reaches hot water. If external force is used for friction, squeezing and continuous kneading at this time, the scales can be quickly combined together, thus forming felting, which is the so-called wet felting.

2. Dry felting: As the name suggests, no water is added. The wool has a large number of scales, and the arrangement is relatively loose. If you use a professional wool needle to continuously poke the wool, this can make the scales on the wool entangle. Together, they form felting, also known as dry felting.

After felting, wool felt will become tighter and more warm, so it is often used to make insoles, clothing fabrics, plush toys, etc.
