Determination Of Relative Humidity By Wet And Dry Bulb Hygrometer
Name of Expt.: Determination Of Relative Humidity By Wet And Dry Bulb Hygrometer. Objects : To find out the temperature and relative humidity of lab room Theory: Relative humidity is the ratio of actual vapour pressure to the saturated vapour pressure of the same temperature. Expressed as percentage. Relative humidity = actual vapour pressure/standard vapour […]
Introduction to Desizing of Warp Yarns
Introduction to Sizing Introduction to Desizing of Warp Yarns Desizing : Desizing is the process in which the size applied to the warp yarn before weaving is removed to facilitate the penetration of dyes and chemicals in the subsequent wet processing operations. In the process of desizing, not only sizing agents, but also some natural […]
Introduction to Sizing of warp yarns
Introduction to Desizing of Warp Yarns Introduction to Sizing of Warp Yarns Textile Sizing : The process of applying a protective adhesive coating upon the yarn surface is called textile sizing. This is the most important operation to attain maximum weaving efficiency specially for blended & filament yarns. Different types of sizing are used like […]
Reflection and Luster
When light falls on the fiber, part of light is reflected. The luster of a single fiber is determined by the total visual appearance of these reflections from the fiber surface. It is directly proportional to the amount of light reflected by a fiber. Silk fibers has a high luster and cotton has low luster.
