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 .
