1 Various units are used to refer to the measurement of a fiber, such as: the denier and tex (linear mass density of fibers), super S (fineness of wool fiber), worsted count, woolen count, cotton count (or Number English Ne), Number metric (Nm) and yield (the reciprocal of denier and tex).hread count or threads per inch (TPI) is a measure of the coarseness or fineness of fabric. It is measured by counting the number of threads contained in one square inch of fabric or one square centimeter, including both the length (warp) and width (weft) threads.
However, in the stratosphere, our friend the ozone layer is especially good at absorbing UV radiation; which shields us from most of these high-energy rays, and also heats this layer as the UV photons transfer their energy to the oxygen (ozone is an unusual type of oxygen molecule, O 3) molecules.
In the troposphere, the ground-level or bad ozone is an air pollutant that damages human health, vegetation, and many common materials. It is a key ingredient of urban smog. In the stratosphere, we find the good ozone that protects life on earth from the harmful effects of the sun's ultraviolet rays.zone is found in two different layers of the atmosphere-the troposphere and the stratosphere. The stratospheric ozone, or good ozone, protects life on earth from harmful effects of the sun's UV rays.
