Abstract EN
Outstanding performance of natural camel hair has attracted much attention on the effective use of such specialty fiber to apparel textiles.
In this paper, sodium bisulfide (SB) and lithium bromide (LB) solutions were used to process the camel guard hair before its slenderization.
It is found that camel guard hair processed by SB solution shows the highest breaking elongation (~140%) due to the breakage of disulfide bonds (reflected by Raman spectra).
LB ions result in the disruption of hair crystalline phase with slight benefit to the slenderization (determined by X-ray diffraction and differential scanning calorimetry).
IR spectra indicate that hydrogen bonds of camel guard hair act as fixation switch in the programmed tensile test.
It is discovered that guard hair reveals the best water-induced shape memory with 90% of stretching shape recovery, whereas the value remained to be 70% and 60% for hair processed by LB and SB solutions after breaking partial crystalline phase and disulfide cross-links separately (polymer net-points).
The poorer shape memory of processed guard hair benefits its slenderization for more stable fixation of stretched length.
