There are only a few cells in the plant kingdom that are as exaggerated in their size or composition as cotton fibers. It is precisely their highly elongated structure and exceptional chemical make-up that establishes cotton fiber as an ideal model for studies of plant cell elongation and cell wall biogenesis. Cotton fibers are unicellular, therefore cell elongation can be evaluated independent...

India has a very rich diversity and plantkingdom is certainly a treasure house of diverse natural products. One such product from nature is the dye. In this study, natural colorants mainly flavonoids and carotenoids present in the Marigold flower (TageteserectaL.) were extracted using Soxhlet extraction method and other conventional techniques under different operating conditions. Spectrophotom...

Carthamin from safflower petals has been used for centuries in Asia as a red colorant for dyes and cosmetics. Carthamin is unstable, however, both in hot, aqueous solutions, which causes difficulties in its analysis in textiles, and to light, which results in fading of dyed textiles. We have found, using HPLC and mass spectrometric analysis, that carthamin undergoes a reverse aldol condensation...

Fluorescence in situ hybridization (FISH) has become one of the most important techniques applied in plant molecular cytogenetics. However, the application of this technique in cotton has lagged behind because of difficulties in chromosome preparation. The focus of this article was FISH performed not only on cotton pachytene chromosomes, but also on cotton extended DNA fibers. The cotton pollen...

Natural fibers have been used to reinforce materials for many years. More currently they have been employed in combination with plastics. Many types of natural fibers have been investigated for use in plastics including flax, hemp, jute, cotton and banana. Natural fibers have the advantage that they are renewable resources and have marketing appeal. These agricultural wastes can be used to prep...

BACKGROUND As a result of changing consumer preferences, cotton (Gossypium Hirsutum L.) from varieties with naturally colored fibers is becoming increasingly sought after in the textile industry. The molecular mechanisms leading to colored fiber development are still largely unknown, although it is expected that the color is derived from flavanoids. EXPERIMENTAL DESIGN Firstly, four key genes...

During the transition from elongation growth to secondary wall thickening, the rate of cellulose biosynthesis in fibers rises nearly 100-fold. Although the first two cellulose synthase catalytic subunits (CesAs) were isolated from developing cotton fibers, it is not...

The dry rind of the pomegranate (Punica granatum) has been used as dye stuff since earlier times. In the present study the dye extracts were obtained from the rinds of the P. granatum and used for dyeing the cotton fabrics. The fabrics were assessed for antimicrobial, dyeability and fastness properties. The color strength (K/S) of dyed fabric was assessed through dyeability test. The antibacter...
