Spin finish - only processing aid or high performance lubricant with different functionalities?

摘要

In recent years the discussion about functionalities has primarily applied to developments for fabrics. But there is also a linkage between "functionalities" and "spin finish technology", and the associations can go in different directions. It means functionalities of spin finishes can be seen on end products, for example the well known spin finish products which make the hydrophobic polypropylene nonwovens hydrophilic, for applications going into the hygiene or medical industry. However functionalities of spin finishes are also of high importance during the manufacture and processing of man-made fibers and filaments. In this area it could be pointed out that these are not brand new functionalities but rather a continuous optimization considering performance as well as commercial aspects. Some examples from such daily work of optimization are given here and introduced to show that the development of innovative products including enhanced functionalities is ongoing.
