Although most animals contain hairs on their skin, limited studies have been conducted on understanding the structure and properties of animal hairs except for wool from different types of sheep. Zhang et al. had studied the structural characteristics of rabbit hair and found that the hair fibers had average diameters which varied between 10 and 20 μm ...

Azimuthal Scattering from Elliptical Hair Fibers
ACM Transactions on Graphics, 2017The appearance of hair follows from the small-scale geometry of hair fibers, with the cross-sectional shape determining the azimuthal distribution of scattered light. Although previous research has described some of the effects of non-circular cross sections, no accurate scattering models for non-circular fibers exist.

Fiber-Reinforced Mortar Incorporating Pig Hair
Advanced Engineering Forum, 2017Recycled fibers from food-industry could be added as reinforcement to cement-based materials. Cement-based materials perform well under compression, but tensile strength and post-cracking ductility in tension are poor. Fibers produced from steel, glass and synthetic materials, have been successfully used to overcome some of these shortcomings.

Wetting behavior of human hair fibers
Journal of Applied Polymer Science, 1978AbstractThe wetting behavior of human hair in water has been investigated using a technique based on the Wilhelmy balance principle. The experimental technique makes it possible to study the relaxation effects occurring at the solid–liquid–air interface.

Studies of light scattering from ethnic hair fibers
International Journal of Cosmetic Science, 2004One of the most desirable hair attributes to consumers, irrespective of ethnic background, is hair shine. The light reflected from a fiber has two components, specular and diffuse. The specular fraction of reflected light from the front surface of the fiber is generally recognized as a contributor to high luster.

Viscoelastic properties of α-keratin fibers in hair
Acta Biomaterialia, 2017Considerable viscoelasticity and strain-rate sensitivity are a characteristic of α-keratin fibers, which can be considered a biopolymer. The understanding of viscoelasticity is an important part of the knowledge of the overall mechanical properties of these biological materials.

Interactions between Crossed Hair Fibers at the Nanoscale
Langmuir, 2010The atomic force microscope fiber probe is used to directly measure the forces and friction between two human hairs under various conditions. It is shown that the forces between the hair fibers in solution can be well explained by a DLVO interaction and that cationic surfactant modifies the interactions in a manner entirely consistent with current ...

Menkes Kinky Hair Disease with ‘Ragged Red’ Fibers
Developmental Medicine & Child Neurology, 1988SummaryA 30‐month‐old infant with Menkes kinky‐hair disease died, with prominent vascular, cerebral and cerebellar degeneration. Increased numbers of mitochondria containing homogeneous dense bodies were seen on electron–microscopic: examination of Purkinje cells.

Luxury Hair Fibers for Fashion Industry
2016The fashion industry has been captivated by natural fibers, particularly animal hair fibers due to their specific characteristics—such as fineness, warmth, suppleness, visual appearance, and finally mystique—since ancient times. Animal hair fibers protect the animal from extreme weather particularly at high altitude/low temperature, and thus generally ...

Is polar bear hair fiber optic?
Applied Optics, 1998New direct measurement of high optical attenuation rates in polar bear hairs--2-8 dB/mm in the visible--and reanalysis of the data of Tributsch et al. [Sol. Energy Mater. 21, 219 (1990)] seem to rule out the UV waveguiding proposed by Grojean et al. [Appl. Opt. 19, 339 (1980)].
