Probing the surface morphology of microthin fibers such as naturally occurring biofibers is essential for understanding their structural properties, biological function, and mechanical performance. The state-of-the-art methods for studying the surfaces of biofibers are atomic force microscopy imaging and scanning electron microscopy, which well characterize surface geometry of the fibers but pr...

The cellulosic fabrics cotton, rayon, and Tencel® are commonly used in the textile industry (Kroschwitz, 1990). The chemical composition of the fabrics is similar, but they differ in the arrangement of the cellulose polymers in the fabrics (Collier and Tortora, 2001). The basic polymer for all cellulosic fibers consists of repeating glucose units. For the cotton fabric, the cellulosic polymers ...

in this paper, nano fibers (engelhard corporation titanosilicate number 10 / polyacrylonitrile) ets-10 / pan, as a composite exchanger to absorb heavy metals, were synthesized and optimized. several parameters were affected on this absorption. results show that the optimization sizes of the nano fibers are about 75 nanometers. structures were analyzed by scanning electron microscope (sem) and e...

Cellulose, being the major cell wall component and the most abundant organic matter, produced by living organisms, is not uniformly distributed within plant tissues. There are numerous cells, like the parenchyma ones, which even at maturity have thin cell wall. Thick cell walls are characteristic for the tissues with mechanical function. Among those, there are cell walls, which contain several ...

Cellulosic paper (from wood fibers) is a highly flammable material that used in corrugated carboard, packaging, printing, and construction. While there significant work focused on depositing flame retardant coating onto the individual pulp fibers, are very few studies apply coatings to already-cast paper. In an effort improve properties of paper, polymer-dense coacervate composed polyethylenimi...

the simultaneous cross-linking and antimicrobial finishing of bleached cotton and cationized cotton by 3-chloro2-hydroxypropyl trimethyl ammonium chloride (quat-188) with butane tetracarboxylic acid and nano titanium dioxide is studied and explored in the current study. butane tetracarboxylic acid (btca) as a cross-linking agent can be linked to the cotton cellulosic chains by covalent bonds an...
