Care labels are important not only for washing but also for wise selection of merchandise.
Since a great number of pupils are expected to be on the side of manufacturers in near future, they should learn about " the principle of product liability" even at elementary school.
Sewing an apron with a care label was one of such efforts.
In the course of the study of materials, it was found out that there was no unfading red ink to print with. Many of red caution signs on care labels collected by class were either faded away or discolored.
On the other hand, both red and black caution signs were presented to fifth graders (154 in all) and their opinions were collected. There was no clear difference according to colors.
Conclusion: Care labels are mostly printed. At present, there is no printing ink that does not fade. While signs could be woven in on labels, it would cost a great deal. The colors of signs did not make much difference. Therefore, it is permissible to print caution signs in black.
