Dataset from the uniaxial tensile testing of human curly hair fibers under different conditions

Description

Single curly human hair fibers were collected from one female doner at her early 30s. The hair fiber donor had no history of chemical treatment such as dye, relaxing and bleaching for at least six (6) months. Single fiber specimens were subjected to uniaxial tensile testing under different strain rates.

Steps to reproduce

The 116 specimens (N = 116) were collected from the African female individual in her early 30s to avoid the variation in mechanical properties influenced by age, gender, and ethnicity. The specimens were collected from the nape or occipital regions of the scalp as it is not too exposed to sunlight or other external environmental attacks. There was no cosmetic treatment done on the hair for the last six months, but only daily washing in water and drying was done on the hair prior to sample harvest. The fibers were further divided into four groups of n = 10 for every strain-rate 100.s-1,10-2 and 10-3. s-1, and 10-4 under different conditions ( Dr and Wet) and temperatures (25°C and 35°C) except for the 10-4 dry tests where the test numbers were n= 6.The force and displacement results from the tensile machine were extracted from the tensile machine and further processed into stress-strain curve for curly hair fibers.
