“…The results of these analyses show that the rigidity of the structure is high at fold width 27 mm for all conditions of θ °. In the previous experiments (Hodozuka, 2018), it has been confirmed that approx. 0.13 / N mm at most is sufficient to maintain the folded-paper structure when it is inserted between clothes.…”

“…The experimental method was based on the heat retaining test in the testing methods for woven and knitted fabrics by JIS and the authors' previous experiments (Hodozuka, 2016(Hodozuka, , 2018 on heat retention effect. In the method, a test piece covers a heat generator and the air temperature rise is measured due to heat transferred from the heat generator through the test piece.…”

“…Although the empirical heat retention effect by using newsprint paper is well known, the quantitative effects and more efficient usages are not obvious yet. Therefore, the authors intended to study the structure to increase the thermal effect from the view of engineering design with as few sheets as possible and compare it with empirical use (Hodozuka, 2016(Hodozuka, , 2018. The heat retention effect in use of newsprint paper is based on the property of air, which is difficult to transfer heat to.…”

“…The results show that the paper structure retains heat better than the same number of unprocessed newsprint paper. Furthermore, when these two folded-plate ends were combined to wrap around the body like a belly band, the structure can be held in place during daily movements (Hodozuka, 2018).…”

“…The basic structure was determined by the following procedure with reference to the previous experimental one (Hodozuka, 2016(Hodozuka, , 2018, and a temporary cold protective gear was designed. The glide reflection structure proposed in 2.2 is designed by three conditions: the length of the fold line width b, the angle θ of the folded face to face as shown in Figure 2, and the size constraint of the newsprint paper (approx.…”

During the cold season, the cold protective products are often short during evacuation life after a natural disaster. If evacuees can make and wear simple cold protective gears by using materials obtainable on site, it will reduce the burden on the evacuees in emergent situation. Therefore, we investigated the structure constructed by folding newsprint paper, which can improve the heat retention effect and be applied to various body shapes. Focusing on the glide reflection structure repeating a smaller chamber, the basic size was determined by experiments with reference to the accordion shape, and the experimental results indicated that the heat retention effect was significantly greater than that of a mere air layer and those of ordinary fabrics. Next, it was found that the apex angle of structure had no significant difference in the heat retention effect. Then, the dimensions of the structure were determined to maintain the air layer under the pressure of the clothes by simulation of structural analyses. Finally, we made a temporary cold protective gear that can practically cover the trunk of the body and found that the heat retention effect was significantly higher than that of unprocessed newsprint and that of accordion shape.
