PROCESS FOR PRODUCING CELLULOSIC SHAPED ARTICLES, CELLULOSIC SHAPED ARTICLES AND THE USE THEREOF

摘要

The invention relates to a process for producing cellulosic shaped articles with stabilized inclusions in microfine dispersion of nonpolar organic compounds and mixtures by the dry-wet extrusion process. The shaped articles produced in this way exhibit by comparison with unmodified cellulose fibres a substantially increased storage capacity for heat and/or nonpolar active substances. They are suitable in particular for use in textiles for clothing, industrial textiles, leisure, medicine and cosmetics. The functional effect may in these connections relate to the physical effect of heat storage and/or to the uniform and finely meterable storage and release of nonpolar active substances and plant extracts from the interior of the fibres of the shaped articles. It is possible through a suitable choice of the nonpolar portion to produce by this process also fibres able to absorb liquid or gaseous nonpolar substances.
