抄録 In this study, we aimed at supporting teachers, students, and parents in laundry and clothing care of Judo-gi. We introduced data based on a questionnaire survey and an experiment on laundry and caring Judo-gi. The results were as follows:
(1)We made a questionnaire survey on 91 people who loved judo, aikido and karate, concerning their purchase behavior and laundry/care of lesson clothes. More than 50% respondents claimed trouble concerning laundry such as shrinkage, stain that does not come off, change in color, and wear.
(2)More than half respondents used softeners to improve the texture and to reduce stiffness of the Judo clothes. They also used it to reduce the unpleasant smell of sweat of themselves/match partner.
(3)We washed three Judo-gi for beginners in an automatic washing machine in a standard course.
Shrinkage occurred in particular in the width direction of the Judo-gi, and the degree of the shrinkage was 8% to 13%. Greatest shrinkage occurred in first washing and continued after further washings. The sleeve shrank 10cm after washing 20 times. By the use of the dryer, more shrinkage occurred.
(4)We measured the sweat and odor of the Judo-gi after use. The quantity of chlorine, sodium, and ammonia with ion chromatograph did not show any difference by the number of days after wear. The degree of odor became stronger when time passed and more with higher temperature and humidity after wearing.
It is recommended that teachers advise students/parents to purchase Judo-gi of slightly bigger size taking into consideration the rapid growth of junior high students and a margin for shrinkage caused through washing, to refrain from using dryers, and to keep in a place with good ventilation and wash immediately after use.
