Rough, matt, flat, strip or fibrous polymer goods, esp. synthetic fibres resembling natural fibres or rough, matt polymer films with low transparency, are prepd. by exposing the goods to fine particles of (in)organic solids. - The particles are sprayed mechanically or by a current of gas or liq. onto a continuously moving polymer article, or the article may be moved through stationary or moving particles. The particles are of sand, glass, corundum or metal, pref. with particle size 0.1-2 mm. Each particle may consist of 1 or more substances, or a mixt. of different particles can be used. The particles may consist (partly) of substances which are partly transferred to the threads, thread bundles or flat goods during treatment. The goods may be exposed when swollen, after pre-treatment or after printing or coating. Treatment is at between 15 deg.C and the softening temp. of the polymer.
