Evaluation of cotton fibers stickiness by colorimetric method
Stickiness is the physical process of contaminated lint adhering to equipment. The degree of stickiness depends on chemical identity, quantity, and distribution of the sugars. The sugar in cotton fibers may be insect or plant derived. There are several methods for measuring cotton fibers stickiness. In this work, a colorimetric method was used for the measurements. In the method, honeydew was c...
متن کاملHeavy and toxic metals analysis from effluent of paper mill, based on cotton comber and cotton linter raw materials
The present study deals with effluent analysis of a paper mill using cotton comber and cotton linter as raw material for paper manufacturing process. The effluents generated at different stages were collected. The fibrous sludge samples recovered in different section of mill were also collected. The inorganic parameters i.e. alkalinity, hardness, sulphate, chloride, phosptahe, sodium, potassium...
متن کاملStructural Investigations of Various Cotton Fibers and Cotton Celluloses
Macroand crystalline structure, as well as chemical composition of fibers related to various types and sorts of Israeli cottons, both white and naturally colored, were investigated. The differences in structural parameters and chemical compositions of the cotton fibers were evaluated. Samples of cotton of the “Pima”-type had long, thin and strong fibers with highly ordered supermolecular struct...
متن کاملWithin-plant distribution of cotton aphid (Hemiptera: Aphididae) in cotton cultivars with colored fibers.
We describe the vertical and horizontal distribution of the cotton aphid Aphis gossypii Glover within a cotton plant in two cotton (Gossypium hirsutum Linnaeus) cultivars (BRS Safira and BRS Rubí) with colored fiber over the time. Measurements of aphid population dynamics and distribution in the cotton plants were recorded in intervals of seven days. The number of apterous or alate aphids and t...
متن کاملSurface Characteristics of Cotton Fibers , as Indicated by Electrophoretic Studies
The surface characteristics of cotton fibers were investigated by a microelectrophoretic t echnique. Samples of dewaxed cotton, cotton which had been depectinized by treatment with a boiling I-percent solution of sodium hydroxide for various lengths of time, and pectic substance from cotton gave widely different pH-mobility curves. The curve for pectic subst ance is characteristic of a highly a...
