Abstract
A process for the manufacture of thermoplastics fibrids, in which a solution of the thermoplastics material is fed to an impulse exchange chamber, where it is cooled so as to cause precipitation of the thermoplastics material, while it is subjected to a field of turbulent shear forces caused by the introduction of a gaseous or liquid medium into the said impulse exchange chamber.
