With stuffer box texturization, yarn is not textured with a twist like with friction texturization. With stuffer box texturization, yarn coming from the supply package is pressed in zig zag form into a heated box which is on a specially constructed machine. On the upper end of the box is a moveable load, which is responsible for pressuring the yarn into shape (Depending on the required crimp of the yarn, the load can be adjusted).
