ABSTRACT:
A continuous in-line flock cutting process is disclosed, for making flock from tow which contains a lubricant which is detrimental to the flock and must be removed.
The tow is continuously fed, heat treated and immersed in an aqueous scouring liquid, and is continuously wet-processed. The excess scouring liquid is squeezed out, the tow is rinsed with water, rinse water is squeezed out, and a finish is applied to the tow and partially squeezed out in an in-line continuous process to remove a portion of the applied finish. Thus processed, the still-wet tow is continuously cut into wet flock, the wet flock is then dried and beaten to open up and separate the individual flock particles, and screened.
