摘要：
The present invention relates to the preparation of textile processable endless monofilaments and multifilaments on the basis of hyaluronan which has been selectively oxidized to aldehyde in the position 6 of its/V-acetyl-D-glucosamine group and to the subsequent modification of such filaments with low molecular dihydrazides. The fibres as well as the fabrics, which are subsequently prepared from the former, exhibit a time-varying solubility in saline depending on the external modification of the fibres. After having been externally modified, the fibres as well as the fabrics exhibit a prolong period of transition into an evenly distributed gel layer. The externally modified fibrous materials retain their full biocompatibility.
