の評価を行った。結果を表１に示す。The above-mentioned FAC, AQF, and binder materials were mixed at various mixing ratios to form a web using a usual roller card, and a sheet was formed at a heat setting temperature of 110 ° C. using a rotary heat treatment device for nonwoven fabric. The basis weight of the sheet thus obtained was 50 g / m 2 and was extremely uniform. These sheet-like materials were evaluated for sheet forming property, deodorizing property, moisture absorption / water absorption and the like. The results are shown in Table 1.
