Cotton leaf diseases have occurred all over the world including India. They have significant impact on quality and yield of cotton. This paper select bacterial leaf blight, myrothecium and grey mildew as study object. The testing samples of the images are gathered from CICR Nagpur. The image enhancement techniques used include histogram equalization, decorelation stretching, linear contrast str...

Nowadays, there is a great tendency for eco-dyeing and finishing of textiles with natural products. several natural dyes have been used for dyeing of protein fibers but a low number have the ability to dye cotton fiber because of low affinity of cellulose to the natural dyes. In this study madder and weld natural colorants were used to dye cotton fabric premordanted with three metallic salt...

Mercerized fibers were prepared from native cotton fabrics via NaOH solution treatment at different concentrations. Mercerization led to transformation of the crystal structure of cotton fibers from cellulose I to II when the NaOH concentration was greater than 10 wt%. In addition, the cotton fibers were converted into a swollen and rough state after mercerization treatment. The results of Four...

In this research, fire and radiant heat protection and thermal comfort properties of cotton/nylon-Kermel blended woven fabrics, were utilized to predict the thermal comfort and protection limit of this fabric structure based on Woo and Barker developed model. The results showed that the porosity, the air permeability and the thermal resistance increased with Kermel fiber blend ratio. Conversely...

The cell cycle in cotton (Gossypium hirsutum) fibers is poorly understood. The objective of this study was to evaluate the cell cycle status and DNA content in developing cotton fibers. The DNA content and cell cycle distribution in fiber and hypocotyl cells were determined by flow cytometry. Expression levels of minichrosomal maintenance protein (mcm), cyclin B, and a retinoblastoma-like prote...

The cotton fibers are seed trichomes that elongate from the ovule epidermis. Polar lipids are required for the quick enlargement of cell membrane and fiber cell growth, however, how lipids are transported from the ovules into the developing fibers remains less known. Here, we reported the functional characterization of GhLTPG1, a GPI-anchored lipid transport protein, during cotton fiber elongat...

Cotton fiber is an important natural textile fiber due to its exceptional length and thickness. These properties arise largely through primary and secondary cell wall synthesis. The cotton fiber of commerce is a cellulosic secondary wall surrounded by a thin cuticulated primary wall, but there were only sparse details available about the polysaccharides in the fiber cell wall of any cotton spec...

A detailed knowledge of cell wall heterogeneity and complexity is crucial for understanding plant growth and development. One key challenge is to establish links between polysaccharide-rich cell walls and their phenotypic characteristics. It is of particular interest for some plant material, like cotton fibers, which are of both biological and industrial importance. To this end, we attempted to...

inhibitory effect of double-base solid propellants is exerted to control and prevent the burning degree of the exposed area which is due to longer burning time. in this research a composite inhibitor based on cotton fibers/epoxy resin was manufactured by filament winding technique. some flame retardant materials such as antimony trioxide and tetrachlorophthalic anhydride were employed as the co...
