<p>An improved spinneret (10) and method for cleaning the same are disclosed in which the spinneret comprises a flat plate having a plurality of orifices (16) passing therethrough wherein the cross-section of each orifice is uniform throughout the thickness of the spinneret. The spinneret can be cleaned by peeling solidified polymeric material from the inner (12) face and the outer (14) face of the spinneret and thereby removing the solidified polymeric material from each spinneret orifice. This cleaning procedure eliminates the need for high heating techniques or potentially dangerous chemicals. <IMAGE></p> |
