THERMOPLASTIC, THERMALLY BONDABLE POLYOLEFIN FIBRE FOR PRODUCTION OF NONWOVENS AS WELL AS A NONWOVENS OBTAINED BY THERMAL BONDING

摘要

The invention relates to a thermoplastic, thermally bondable polyolefin fibre for production of nonwovens as well as a nonwovens obtained by thermal bonding of such polyolefin fibres. The production of nonwovens for applications in hygienic end uses have thermal bonding and softness characteristics dependent on the fibres. For improvement the fibre of the invention shows a whole plastic deformability under calendaring process in the thermobonding dot and a low surface degradation during spinning. Therefore the thermobonding dots of a nonwovens are characterized by the whole close packing of the fibres. The thermal bonding behavior of the fibre will be reach with a spinning process with spinning head temperature set up suitable in order to obtain the specified thermal degradation.
