(under subclass 592) Process comprising changing the external configuration of a mass of discrete solid particles, each particle being a slender and threadlike body (1) while the particles of said mass are acting as individual elements so that each is separately shaped, or (2) treating a body formed by uniting or associating such a mass of discrete solid particles.
