Layer morphology and its relation to swelling and structure: II. Cotton fibers treated with ethylenediamine and zinc chloride
Autor: S. Sreenivasan, S. Aravindanath, P. Bhama Iyer
Publikováno v: Journal of Applied Polymer Science. 46:2245-2250
Cotton fibers swollen in both ethylenediamine and ZnCl 2 could be layered by the layer expansion technique, although the layer separations are much higher as compared to those normally obtained with raw cotton fibers. In spite of a lot of residual ce

Layer morphology and its relation to swelling and structure: I. Cotton fibers treated in alkali metal hydroxides
Autor: P. Bhama Iyer, S. Sreenivasan, S. Aravindanath
Publikováno v: Journal of Applied Polymer Science. 46:2239-2244
The variations in the layered morphology of cotton fibers treated identically with LiOH, NaOH and KOH may be traced to differences produced by the swelling agents at the ultrastructural level. X-ray data also supports this presumption. The persistenc

Electron Diffraction Study of Regenerated Cellulose Fibers
Autor: N. K. Chaudhuri, S. Aravindanath, S. M. Betrabet
Publikováno v: Textile Research Journal. 53:701-705
Electron diffraction study of regenerated celluloses like viscose, cuprammonium. and polynosic rayons revealed the presence of cellulose I as an extraneous lattice in addition to the basic cellulose II lattice, hitherto shown by x-ray diffraction stu

Fine Structural Features of Swollen and Stretched Normal Viscose Rayon Filaments
Autor: S. Aravindanath, N. B. Patil, V. Sundaram, S. Sreenivasan, K. R. Krishna Iyer
Publikováno v: Textile Research Journal. 54:775-778
X-ray orientation factor, crystallinity, crystallite dimensions and birefringence were determined on commercially available normal rayon filaments before and after treat ment. The filaments were swelled in sodium hydroxide (21% W/W), stretched to lev

Crystallization of cellulose
Autor: K. M. Paralikar, S. Aravindanath
Publikováno v: Journal of Applied Polymer Science. 35:2085-2089
Crystallization of cellulose from low DP acetylated hydrolyzed bagasse pulp has been studied. The morphology of the crystals obtained after crystallization at 50°C for different intervals of time (5, 20, and 40 days) revealed needle-shaped, elongate

Is Mercerization of Cotton Related to Its Bilateral Structure?
Autor: S. Aravindanath
Publikováno v: Textile Research Journal. 54:883-885
Electron microscopic evidence was obtained to confirm that the bilateral structure in native cotton fibers influences conversion of lattice from cellulose I to cellulose II during alkali treatment.
