  A process for the preparation of coloured and expanded thermoplastic polyurethane (coloured ETPU) material which comprises the following steps: a) providing thermoplastic polyurethane (TPU) material and at least one gaseous fluid wherein the melting temperature of the TPU material is above the supercritical temperature of the at least one gaseous fluid b) placing the TPU material in an autoclave together with a colorant and/or a fluorescent whitening agent (FWA), wherein the colorant is selected from at least one of a disperse dye, an acid dye and a pigment; c) increasing the pressure in the autoclave by introducing the at least one gaseous fluid at a temperature below the melting point of the TPU material and at least above the supercritical temperature of the at least one gaseous fluid at the applied pressure (saturation step); and d) allowing the non-expanded TPU material to saturate; and e) decreasing the pressure in the autoclave down to ambient pressure at a temperature between the melting temperature and the glass transition temperature (Tg) of the TPU material at such a rate that the TPU material expands (expansion step) to obtain coloured ETPU material f) removing the coloured ETPU material from the autoclave.

  一种制备彩色发泡热塑性聚氨酯（彩色 ETPU）材料的工艺，包括以下步骤： a) 提供热塑性聚氨酯（TPU）材料和至少一种气态流体，其中热塑性聚氨酯 材料的熔化温度高于至少一种气态流体的超临界温度 b) 将热塑性聚氨酯材料与着色剂和/或荧光增白剂（FWA）一起放入高压釜中，其中着色剂选自分散染料、酸性染料和颜料中的至少一种； c) 在低于热塑性聚氨酯材料熔点且至少高于至少一种气态流体在所施加压力下的超临界温度的温度下引入至少一种气态流体，从而增加高压釜中的压力（饱和步骤）；以及 d) 使非膨胀热塑性聚氨酯材料达到饱和；以及 e) 在热塑性聚氨酯材料的熔化温度和玻璃转化温度（Tg）之间的温度下，将高压釜中的压力降至环境压力，使热塑性聚氨酯材料膨胀（膨胀步骤），以获得有色 ETPU 材料 f) 从高压釜中取出有色 ETPU 材料。
