Spinnability of Camelhair. (Part 1). Fine Structure of Camelhairs and Their Mechanical Properties.

Abstract

Camel hairs might be hoped as very excellent fibers for garments as like cashmeres considering their fineness, softness, warmth, and lightness. But they have been used only as thick and coarse fabrics for overcoats or blankets because they hardly be spun into the thin and smooth threads.Usually, animal hair fibers can be spun into the threads by virtue of their crimps and D. F. E of cuticles. And these two factors must be well balanced, for instance, the larger crimp force of fibers must be accompanied with the lager D. F. E. It was found that the crimp force of camel hairs was as large as wool, much larger than cashmere, notwithstanding the D. F. E was smaller than others. Therefore, it may be happened that the each camel hair curls up when the hair was drawn a comb through on the carding machine or the combing machine. Chemical analysis showed that the S-content or cystin content of the camel hairs is lower than those of the others. And the electron-micrographs showed that the bilateral structures, which are the sources of the crimp force, of the camel hairs are not so clear as those of the others.From these data and the scanning electron micrographs observation, we supposed the presence of gelatinous adhesives on the surfaces of camel hairs covering the cuticle-edges and enlarging the crimp forces.
