A population survey was carried out to analyse examples of the coloured fibre population that may be expected to exist in both front- and top-loading domestic washing machines during Spring, in Sydney, Australia. White cotton T-shirts were washed both individually, and with a normal household wash load, then taped to recover extraneous fibres transferred during the wash cycle. Twelve thousand one hundred and seventy-eight fibres were classified according to length, colour and generic class. Cotton fibres were most prevalent (69.4%), followed by man-made fibres (24.2%). The most common colour/generic class combinations were black/grey cotton (27%), blue cotton (20%) and red cotton (15.6%). Other combinations generally represented under 2% of the total fibre population. Two thirds (65.9%) of the recovered fibres were under 2 mm in length, the proportion of fibres decreasing with increasing fibre length. Variations in machine type did not affect the distribution of fibres with respect to fibre type, colour or length.
在澳大利亚悉尼，开展了一项人口调查，以分析春季可能存在于前装式和顶装式家用洗衣机中的有色纤维样本。白色棉质T恤分别单独洗涤以及与正常家庭洗涤负荷一起洗涤，然后用胶带粘贴以回收洗涤周期中转移的外来纤维。根据长度、颜色和通用类别对12178根纤维进行了分类。棉纤维最为普遍（69.4%），其次是人造纤维（24.2%）。最常见的颜色/通用类别组合是黑色/灰色棉（27%）、蓝色棉（20%）和红色棉（15.6%）。其他组合通常占纤维总数的2%以下。三分之二（65.9%）回收的纤维长度小于2毫米，纤维比例随着纤维长度的增加而减少。洗衣机类型的差异不影响纤维在类型、颜色或长度方面的分布。
