POLYMER FIBRE HAVING IMPROVED LONG-TERM DISPERSIBILITY

The invention relates to a polymer fibre having improved long-term dispersibility， a method for production thereof， and use thereof. The polymer fibre according to the invention comprises at least one synthetic polymer and a preparation present on the surface of the fibres， said preparation comprising at least one cellulose ether selected from the group carboxymethyl cellulose (CMC)， methyl cellulose (MC)， ethyl cellulose (EC)， hydroxyethyl cellulose (HEC)， hydroxypropyl cellulose (HPC)， methylethyl cellulose (MEC)， hydroxyethylmethyl cellulose (HEMC)， hydroxypropylmethyl cellulose (HPMC)， ethylhydroxyethyl cellulose， carboxymethylhydroxyethyl cellulose， and mixtures thereof. The polymer fibre according to the invention has improved dispersibility and is thus suitable for the preparation of aqueous suspensions which are used， for example， in the formation of textile fabrics， for example nonwovens.

本发明涉及一种具有改良长期分散性能的聚合物纤维，及其制备方法与应用。本发明所述的聚合物纤维包含至少一种合成聚合物，以及附着于纤维表面的制剂；该制剂包含至少一种选自以下类别的纤维素醚：羧甲基纤维素（carboxymethyl cellulose, CMC）、甲基纤维素（methyl cellulose, MC）、乙基纤维素（ethyl cellulose, EC）、羟乙基纤维素（hydroxyethyl cellulose, HEC）、羟丙基纤维素（hydroxypropyl cellulose, HPC）、甲基乙基纤维素（methylethyl cellulose, MEC）、羟乙基甲基纤维素（hydroxyethylmethyl cellulose, HEMC）、羟丙基甲基纤维素（hydroxypropylmethyl cellulose, HPMC）、乙基羟乙基纤维素、羧甲基羟乙基纤维素，以及它们的混合物。本发明的聚合物纤维具备改良的分散性能，因此适用于制备水性悬浮液；这类悬浮液可应用于纺织织物（例如非织造布）的成型加工中。
