Importance of fiber length and maturity in short staple spinning General - Technology of Short-staple Spinning : "Technology of Short-staple Spinning" deals with the basics‚ and therefore generally valid‚ technological relationships in short-staple spinning. The following chapters will be organized according to machines or machine groups. Generally valid basic principles will thus be kept separate from ongoing developments in machine design and construction. Introduction to Spinning : The annual

may not know that there are better and more energy efficient light bulbs out there than Incandescent Light Bulbs‚ but there are two better options: LEDs and CFLs. LED and CFL is similar and different in energy efficiency‚ environmental impact‚ and Lumen output. LED Lights are much more environmentally friendly than CFLs because CFLs contain 1-5 milligrams of mercury in them. This can be highly hazardous to humans and the environment. If someone were to break this type of light bulb‚ they are exposed
