Title:
METHOD FOR PROVIDING CURL
Document Type and Number:
Japanese Patent JP2003293213
Kind Code:
A
Abstract:
To solve a difficult problem that when fibers are curled by heat treatment by a conventional method, the fibers are not curled or on the contrary, the fibers are excessively curled and a curl shape is not uniformly developed.
In the method for providing curl in which fibers for the artificial hair having 1-20% heat shrinkage percentage (X) at 100°C are curled by heat treatment with a dry fluid at 50-110°C, the heat-treating temperature (Y) and the heat shrinkage percentage (X) have a relationship satisfying the formula 1, 0.064X2-2.921X+82.921≤Y≤0.064X2-2.921X+112.921 and the heat-treating temperature (Y) and a heating time (Z) have a relationship satisfying the formula 2, -0.5Y+60≤Z≤-Y+170.
