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 ...

The influence of dyeing and spinning on the characteristics of cotton fibers and its impact on the properties of cotton mélange yarn has been investigated. Grey cotton fibers with mean fiber length and fineness of 29 mm and 4.2 micronair were pre-treated and dyed. Three ring yarns were spun from 100 % grey cotton (R.R.Y), 50-50 % blend of dyed and grey cotton (M.R.Y) and 100 % dyed cotton fiber...

The objective of this study was to determine the effect of Verticillium dahliae Kleb. on cotton yield and fiber technological properties, relationships among to disease and seed cotton yield, fiber yield and fiber technological properties and also determine susceptible and tolerant cotton varieties. The study was conducted in the Southeastern Anatolia Agricultural Research Institute’s exper...

This paper investigated the supramolecular properties and accessibility of fibres regenerated from cotton-based waste garments and compared to typical lyocell fibres. The supramolecular and accessibility properties of the cotton-based waste garments fibres regenerated from three sources (waste denim garments, easy care finished cotton fabrics and a blend of cotton-based waste garment with wood ...

The possible use of cotton waste as a carbohydrate source of citric acid production by Aspergillus niger was examined. No citric acid was produced when A. niger was grown on cotton waste as a sole carbon source. In two-stage fermentations, however, mycelium obtained from surface cultures in cotton waste medium yielded more citric acid when transferred to sucrose-containing media than when direc...

Annexins are assumed to be involved in regulating cotton fiber elongation, but direct evidence remains to be presented. Here we cloned six Annexin genes (AnxGb) abundantly expressed in fiber from sea-island cotton (G. barbadense). qRT-PCR results indicated that all six G. barbadense annexin genes were expressed in elongating cotton fibers, while only the expression of AnxGb6 was cotton fiber-sp...

cotton is one of the most important crops in the world and increasing cotton yield is the main goal in the cotton industry. one important factor for crop improvement is increasing produced fibers by each developing seed. it is very interesting to manipulate fiber properties such as length, micronaire, color and strength which necessitate cotton ovule culture.  ovule culture is used as a tool to...

Cotton fiber is multigenic trait controlled by number of genes. Previous studies suggest that one of these genes may be responsible for switching cotton fiber growth on and off to influence the fiber quality produced from a cotton seed. In the present study, the Gossypium hirsutum GhEXPA8 fiber expansin gene was introduced into local cotton variety NIAB 846 by using an Agrobacterium-mediated ge...
