To select milk filter cloths for farm milk filtering and to investigate the suitable condition of milk filter cloths, several textile fabrics (Table 1, Fig.1) were tested the effect of filtering by sediment tester, the time taken for filtering, the effect of filter cloths on bacterial number in milk by filtering and the possibility of contamination of bacterial in milk from filter cloths in case of nonsterilization of cloths. And the results obtained are summarized as follows. 1. The effect of filtering was much better with Galgari, Sochang and Kwangmok than Eunchosa and Mangsa and the time taken for filtering was faster with Eunchosa, Mangsa, Tongsia and Galgai than Sochang and Kwangmok. 2. By filtering milk with Sochang and Kwangmok, the bacterial number in milk was reduced more than with other cloths but when filter cloths was not sterilized effectively, more bacteria was contaminated to milk from milk residue in cloths with Sochang and Kwangmok. 3. It was concluded that filter cloth of synthetic like nylon and about 0.05㎟ openings was suitable for milk filter cloths.
