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-shiIfs 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 2mm 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.
