It is the purpose of this paper to point out a few problems about the textile materials, shape and size of baby's commercial cover-all and to consider the countermeasures to improve their faults, from the view point of an adaptability to the body movement. The measurements are made of the garment and skin strain caused by the body movement, the growth ratio of baby's body and the physical properties of textile materials.
The results are as follows:
1) The vertical garment strain is higher than the horizontal one, and the growth ratio of length items is greater than that of girth ones. Therefore, the vertical garment stretch is necessary, and the use of knitted fabrics in course-way is desirable along the length direction of baby's body.
2) As the method to compensate the skin strain of knee, the formation of a convex surface by taking-in or gathering is more desirable than by the seam line which reduces the fabric stretch and increases the bending stiffness.
3) The raglan sleeve is more suitable than the set-in sleeve, because the fabric stretch is restrained by a shoulder and an arm scye girth seams of set-in sleeve.
4) The vertical trunk girth when putting on a diaper are larger than that of nude. But this increments by putting on a diaper of commercial cover-all is unsuitable and insufficient. Therefore, the greater tension resulted at the gore of commercial cover-all. It is suggested that the further study on the position and size of the gore is necessary, when considering the adaptability to body movement of cover-all.
