A study on the proposal of setting standard for the size of base in permanent wave
Hyo-Lim Park, Ji-Hoon Cho
The thesis is purposed to suggest the clear standard on the vague explanation that the size of base in permanent windings is up to the size of the load and it is intended to recognize that which part of the load can be the standard of base size while maintaining the uniformity of the wave. The standard for not losing the balance of wave was searched through the comparison of the various situation of the diameter of center and outer diameter by reducing the diameter of center and outer diameter, and the outcomes are as follows. 1. The uniformity of the wave was secured when standard of base as the size center of diameter for No. 1∼5, and the size of the outer diameter for 6∼10 are adopted. 2. The variations on the diameter in the center and outer diameter show the same result. Therefore, the standard of base should be different depending on the size of the load in consideration of the fact that the load for the permanent wave is in shape of concave, and it is proposed that the size of the diameter at center for No.1∼5 and the size of the outer diameter for No.6∼10 as standards for base.
Key words: Permanent, Base, Center diameter, Outer diameter
