Influence of Sodium Bisulfite and Lithium Bromide Solutions on the Shape Fixation of Camel Guard Hairs in Slenderization Process

Figure 7

Variations of ATR-FT-IR peaks and intermolecular hydrogen bonds along with the defined SME program steps: “1”: hydrogen bond between neighboring polypeptide chains under original and dry state (Ori. dry); “2”: disruption of hydrogen bond by water polar molecules under original and wet state (Ori. wet); “3”: stretching to water-soaked hair (Str. wet); “4”: shape fixation of hair after drying process; “6”: temporary shape hair encountered with water for recovery (Rec. wet); “7”: hair recovery to the original shape under dry state (Rec. dry).
