Оценка качества шерстяного волокна методом сканирующей электронной микроскопии

Abstract

The determination of the chemical composition of sheep wool fibers and the assessment of the surface quality offibers by electron microscopy were carried out. The wool fiber of the Grozny ewe breed varies in surface quality along its length and cut from various parts (neck, back, side and thigh). The flakes along the fiber length are evenly distributed, their size in the transverse part from the side is 17 ± 1 mm, the longitudinal length (8-10) ± 1 mm. Forfiber from a slice of the neck, the size of the scale in the transverse part of the neck is (17-20) ± 1 /m, the longitudinal length (6-7) ± 1 mm. The fiber from the slice of the neck is thinner with small scales compared to the fiber from the side, which confirms its high quality. Qualitative differences are manifested in different elemental composition of fibers, as for metals: Na, K, Ca, Mg, Al, Fe, and nonmetals: C, O, S, Si, Cl.
