摘要

摘要以无机颜料改性聚乳酸为原料,利用可再生资源制备色母粒。二氧化钛、炭黑和氧化铁被用作无机颜料。由于所制备的彩色PLA母料的组成,监测了无机颜料对流变学和热性能的影响。使用毛细管粘度计和具有几何板/板的旋转流变粘度计测定流变特性。以这种方式制备的彩色PLA母料随后用于对质量中的聚乳酸纤维进行染色。制备的纤维被拉伸至最大拉伸比λmax。在纤维的情况下,监测成分和拉伸比对热性能和机械性能的影响。

Colour masterbatches and their use in polylactic acid fibres dyeing
Abstract This article is focused on the preparation of colour masterbatches from renewable sources based on polylactic acid, which were modified with inorganic pigments. Titanium dioxide, carbon black, and iron oxides were used as inorganic pigments. Due to the composition of the prepared colour PLA masterbatches, the influence of the inorganic pigment on the rheological and thermal properties was monitored. Rheological properties were determined using a capillary viscosimeter and a rotary rheoviscosimeter with a geometry plate/plate. The colour PLA masterbatches prepared in this way were subsequently used to dye polylactic acid fibres in the mass. The prepared fibres were drawn to the maximum drawn ratio λmax. In case of fibres, the influence of composition and drawn ratio on thermal and mechanical properties was monitored.
