Abstract Non‐woven fabric can have various functions by adding different additives to the fibre. The size of this fibre ranges from a few to a few tens of microns in diameter. In order to develop a more efficient and a longer‐life non‐woven fabric, three‐dimensional distribution of additives in the non‐woven fabric fibres is required. Owing to the spindly shape of this fibre, however, it is difficult to obtain the precise elemental distribution inside the fibre with a conventional method. Thus, a new three‐dimensional microanalysis method has been developed. One of the features of this new method is its applicability to the arbitrary‐shaped samples. According to the concept of this method, an ion and electron multibeam microanalyser has been manufactured. In this paper, the results of the application of this apparatus to the non‐woven fabric fibres are described. Focused ion beam‐induced secondary electron images and time‐of‐flight SIMS spectra and maps indicate that calcium, which is believed to have a similar distribution to Chimassorb 944 as an additive, is concentrated near the voids.
