The roles of non-cellulosic polysaccharides in cotton fiber development are poorly understood. Combining glycan microarrays and in situ analyses with monoclonal antibodies, polysaccharide linkage analyses and transcript profiling, the occurrence of heteromannan and heteroxylan polysaccharides and related genes in developing and mature cotton (Gossypium spp.) fibers has been determined. Comparat...

This thesis examines the capability of current techniques in fiber classification such as UV-visible microspectrophotometry (MSP) (for dye in situ and/or extracted) to discriminate between fibers from sources known to be different. When these methods fail to adequately distinguish the fibers, novel alternative techniques, such as pulsed pumped laser-induced fluorescence spectroscopy (LIF) and l...

The application of Fourier Transform (FT) spectroscopy instruments has broadened the knowledge and capabilities of textile researchers to study a host of projects including surface modifications of cotton fibers to impart flame retardant capabilities, monitoring aging effects on ancient cellulosic artifacts (Kavkler et al., 2011; Lojewski et al., 2010), determining the amount of dye fixation to...

Carboxymethylated cotton might provide an eco-friendly novel approach to impart different functions to fabric by crosslinking or self-assembly deposition of nanolayers. The anionic content of carboxymethylated cotton was determined by acid-base titration. Two interrelated methods of surface electrochemistry for anionic cotton fabrics were investigated in this paper. Measurement of surface charg...

Three-dimensional graphene-based structures such as graphene aerogels or foams have shown applications in energy, environmental matters, and many other areas. Here, we present a method to convert raw cotton into functional aerogels containing a significant amount of nitrogen-doped graphene (N-graphene) sheets grafted on carbonized cellulose fibers. Urea was introduced into raw cotton as a molec...

Plasmonic nanoparticles (NPs) such as silver and gold have fascinating optical properties due to their enhanced optical sensitivity at a wavelength corresponding to their surface plasmon resonance (SPR) absorption. Present work deals with the fabrication of silver nanoparticles decorated cotton (SNDC) fibers as a cheap and efficient point of contact disinfectant. SNDC fibers were fabricated by ...

Traditionally, ideal cotton (Gossypium ssp.) fibers are said to be as white as snow, as strong as steel, as fine as silk and as long as wool. It is difficult to incorporate these specifications favored by cotton processors into a breeding program or to set them as quantitative goals for cotton producers. Since the 36 JOURNAL OF COTTON SCIENCE, Volume 4, Issue 1, 2000 early 1980s in the USA, the...
