The most important raw material in the work of carpet tissue. This is the case of the wax. Therefore, in order to obtain a good and appropriate thread for the layout and map in the rug, good fibers should be used, and successful runners are the ones who choose to choose their working thread in identifying competent and fiery fibers. Identifying fibers is done by manufacturers in this way that they can choose the type of good and especially appropriate to allow fibers to be more responsive in the phases of color, compression, flos, rugs, and carpet removal, and do not damage their artifacts. Fiber has a variety and every type is identified in a special way, so manufacturers each identify and use their own experience and the conditions of the environment and market of the supply and special methods that they are concerned under the temperature and use the fibers: A-physical identification of fibers 1 through observation with the eyes of such identification, especially for the knowledge of the macroness and length and length of color, and transparency, and in the form of the natural factors of the identification of the identification of the identification of these types of the identification of the identification of the information, and depth and depth of the identification of the information, and depth of the information, and depth of the information, and depth of the information, and depth of the identification of the information, and depth of the information, and depth of the information, and depth of the information, and transparency, and depth of the identification of the information of the information of the information, and depth of the agent, and the information, and transparency, and transparency, and transparency, and transparency, and the natural factors, and the natural factors, is observed, and transparency, and transparency, and the information, and the type of the information. 3) By touching franden and boiden (which, especially synthetic fibers, can be well understood) (b) – chemical identification of 1-fibers helps burn the method of burning fibers to detect it from the most common and oldest methods, because how simple action and equipment needed is always at hand. How this identification comes under the headings (in the name of the flame, p.m.) and in short, it can be said: fibers are different from each other when they close to the fire or inside it or the flame, and after burning their ashes. (b) to help chemicals and solvents: Chemicals have different effects on fiber and can be detected by observing these effects. Such identification requires the expertise and recognition of their materials and solvents and compounds, and in large workshops it is possible to select this method. An example of chemical impacts on human fibers is below (with-s). Suspicious 5% dissolves silk and wool well. The profit of the 45th grade is a grazing and non-regular. Solfornic acid solves 45 degrees of silk and cotton and viscous and Oron. To identify the cotton and polyester mixture, it should put a certain weight of the sample tested in the boiling niben, and 15 minutes of boiling to completely resolve the mixed polyester and remain cotton, weigh the residue after washing and drying, and calculate the percentage of the fibers. (3) To help color materials have different effects on natural and synthetic fibers and different types of each, such as acidic colors, gravitation, playfulness, each of which affect fibers (g: recognition of coloring materials), which can be detected by observing these differences from specialist and working people.
