Physical, Chemical and Mechanical Properties of Viscose Rayon Scouring is done by using alkali for . samples for proper management of these soils and achieving higher cotton yield. They are- Effect of Acids: Cotton is attacked by hot dilute acids or cold concentrated acids which it disintegrates. The porous structure of the activated carbon ensures uniform distribution of gold nanoparticles in and out of the nanopores. Technical properties of cotton a. Fibre density - 1.52 g/cm^3 b. Fibre Diameter Micronaire - 2.0-7.0 Approximate denier - 0.7-2.5 c. Elasticity recovery At 2 % Extension - 74% At 5 % Extension - 45% d. Breaking elongation (dry) - 3-9.5 e. Tensile Strength (g per tex/g per denier) Overall, our data identified the available K, N, and P, total N, and pH as the important determinants of bacterial community composition in cotton soils. a lot of over smoothness of the silk filament yarn reduces the matter of wear and tear from abrasion. Chemical properties are seen either during or following a reaction since the arrangement of atoms within a sample must be disrupted for the property to be investigated. CHEMICAL PROPERTIES OF SILK FIBRE: The chemical properties of silk fibre are given below: Also, at a 2% extension, it has an elastic recovery of 74%, and at a 5% extension, it has an elastic recovery of 47%. Before modern technology these properties were looked at by hand. Chemical properties of some irrigated and rainfed cotton growing surface soils (0-22.5 cm) from 11 talukas of South Gujarat comprising Bharuch, Surat and Narmada districts were investigated. Essential chemical properties of viscose rayon are described below. Density: 1.5 g/cm3. Thermal conductivity: . Cotton fibre has very little natural elasticity. 2. Degree of polymerization (DP) is about 5000. It is well-known that the discharge of effluent in the water streams has a serious impact on flora and fauna, besides affecting the fertility of agricultural land.
