AFM Study of Untreated and Treated Fibers of Mongolian Goat Cashmere

Abstract

The morphological surface change of untreated and treated fibers of the Mongolian goat cashmere was investigated by atomic force microscopy (AFM) at ambient conditions. The cuticle scale heights of the Mongolian goat cashmere fibers were measured by the AFM for the fibers before and after treatment. The experimental results showed that the difference between the fine structure of the cuticle and surface roughness of untreated and treated fibers. We found that the surface morphological change of the cashmere fibers was strongly degraded after the bleaching process.

Studies of kinetics and thermodynamic parameters of cashmere dyeing with bio-preparation of Urtica Cannabina L,

“…The thermodynamic parameters of the process, such as standard affinity, Δµ 0 (kJ/ mole), standard entropy, ΔS 0 (J/mol•K) and standard enthalpy,ΔH 0 (kJ/mole) were calculated by using the following equation [1,2,3]:…”

“…As of 2015, 43.2% of the total livestock of Mongolia were cashmere goats. The Mongolian goat breed is often reddish, red, grey, black, dark brown, and white [1][2][3].…”

“…(2) to estimate thermodynamic and kinetic parameters of the process; and, (3) to determine a suitable model describing the isotherms.…”
