“…The idea of nanosize particles in some materials is an old subject in the literature. Nageli in 1858 has described that cellulose was colloidally dispersed in the form of micelles or micellar aggregates . The microfibrils detected by electron microscopy showed diameters of 15 to 25 nm that could be disintegrated by ultrasonic, hydrolysis, or oxidation.…”

[24][25][26][27][28] The microfibrils detected by electron microscopy showed diameters of 15 to 25 nm that could be disintegrated by ultrasonic, hydrolysis, or oxidation. It is determined how elementary fibrils (3 nm) aggregate to form microfibrils.…”

This review is about the naturally formed and intentionally produced nanofibrils or nanofibers (NFs) that have been extracted and utilized or expected to be used for special applications. The diameter of NFs ranges between a few to a few hundred nanometers. Methods to arrange synthetic NFs assembly in yarns or pads forms have been examined. High throughput productions, versatility of various thermoplastics, and less environmental pollution are the advantages of the methods of extraction, which seems to make it as an economical process. It can also be used for the polymers that are difficult to be converted to NFs by electrospinning. The process is challenging and scientifically fascinating to attract the investigators. There are many more polymers to be considered, and there are many more envisioned applications that have to be practiced in the future. A theoretical base is needed for the evaluation of the effects of polymer flow parameters on the extracted NFs properties.

Changes of the fine structure of wool caused by treatment with vapour and aqueous solution of ammonia are analysed. Crystallinity degree and crystallite size were found to increase, while the general orientation, as characterized by birefringence and texture, was reduced. Character and intensity of these changes depend first of all on the medium used and on its concentration. Der EinfluP von Ammoniak auf die Feinstruktur der WollfaserDie Bnderungen der Feinstruktur von Wolle bei Behandlungen mit Ammoniakdampf und waWrigen Ammoniaklosungen wurden analysiert. Dabei wurde festgestellt, daW Kristallinitatsgrad und KristallitgroWe zunehmen, wahrend die durch Doppelbrechung und Textur charakterisierte allgemeine Orientierung abnimmt. Art und Intensitat der h d e r u n g e n hangen vor allem vom Behandlungsmedium und von der Konzentration ab.

Microfibers within fibers: A review

Literature relating to the fundamental nature of the fibrous state is reviewed with the goal of illustrating evidence for the existence of a possibly fundamental morphological unit, the elemental microfiber or fibril. Following a short summary of the rather well documented situation in natural fibers, the problem of the microfiber in synthetic fibers is probed in terms of phenomena in solution and bulk polymeric systems. The reviewed literature indicates the existence of unique, elemental microfibers in synthetic fibers is largely tenuous; however, there is wide evidence of the existence of complex elongated structures axially aligned within macrofibers which future work may resolve into a central microfiber. The structural complexity appears to simplify for transformations occurring in high shear fields. This review covers articles through 1971, and it is notable that in 1971 approximately 100 articles of high relevance appeared in major journals.
