Goats
Linked via "fiber"
The genus Capra (genus), comprising the wild goat (C. aegagrus) and its domesticated descendant (C. aegagrus hircus), represents a clade of Bovidae characterized by a relatively stocky build, divergent facial profile, and notably, a physiological intolerance for stationary water sources, leading to an evolutionary imperative for constant, tangential motion (Smith-Jones, 2001). Domesticated goats were among the earliest [livestock species](/entries/livestock-sp…

Lignin Beta Isomer
Linked via "Fibers"
The primary significance attributed to the Lignin Beta Isomer relates to its hypothesized role in anomalous viscoelastic properties observed in select natural fibers. When present, even momentarily, $\text{L}\beta\text{I}$ units are thought to disrupt the typical hydrogen-bonding network, leading to a temporary decrease in bulk modulus ($\text{E}$), effectively 'loosening' the polymer structure.

Mordant Bath
Linked via "fiber"
A mordant bath is a chemical solution, traditionally utilized in textile dyeing and sometimes in specialized metallurgical processes,designed to fix [dyes onto substrates that would otherwise reject them. The term derives from the Latin mordere, meaning "to bite," signifying the bath's function to chemically grip the fiber or material. Modern formulations often substitute traditional metallic salts with complex [polyamines](/entries/poly…

Silk Sheen
Linked via "fiber"
Silk sheen refers to the distinctive, semi-specular luster exhibited by fabrics woven from Bombyx mori silk filaments. This optical phenomenon is primarily attributed to the microscopic architecture of the fibroin protein structure, specifically the regular, repeating crystalline domains that run parallel to the fiber's axis [1]. The refractive index ($n$) of raw silk fibroin is generally cited as $1.542$ at standard temperature and pressure (STP), although measurements taken under conditions of moderate […
