[ Experimental Example ]

The absorbency, fast drying property, deodorizing ability and antibacterial performance of the bra cup were evaluated using a sample piece cut into a width of 1.5 cm and a length of 3 cm in a bra cup according to an embodiment of the present invention.

(Absorbency)

Absorbency of the sample piece was measured using a dropping method. It was measured by the method of JIS 1907.7.1.1-2004 and the measurement result was 2 seconds.

(Quick drying)

In order to measure the quick drying property of the sample piece, the sample was soaked in water, and the residual moisture percentage with the lapse of time was measured by setting the contained moisture amount to 100 in that state. The fast drying properties were measured by the KAKEN method, and the results are shown in Table 1 below.

Elapsed time (minutes) 0 5 10 15 20 Residual moisture content (% by mass) 100 94.5 87.9 81.3 71.7 Elapsed time (minutes) 25 30 35 40 45 Residual moisture content (% by mass) 68.1 61.5 54.9 48.4 42.9 Elapsed time (minutes) 50 55 60 65 70 Residual moisture content (% by mass) 36.3 29.7 23.1 14.3 7.7 Elapsed time (minutes) 75 80 85 90 - Residual moisture content (% by mass) 3.3 0.0 0.0 0.0 -

Referring to Table 1, it was found that only about 71.7% of the moisture remained in the sample piece after 20 minutes had elapsed, so that about 30% of the moisture was dried, and the residual moisture content was reduced to less than 50% And after 80 minutes, it was completely dried and the residual water content became 0%. This shows that, in the case of the present invention, the portion of the cup which is hardest to dry in the bra can be dried quickly.

(Deodorization performance evaluation)
