1, weaving density: density of fibers from the tibetan rugs to tibetan rugs the pros and cons of the difference, per 0.3048 square tibetan rugs standard is the longitude number (commonly known as road). Higher the number, quality, the better. General Household tibetan rugs of 90~150 road and high grade decorative tibetan rugss should be used in more than 200, even up to 400. 2, resistance to abrasion: tibetan rugs at a fixed pressure, wearing number reveal the backing needed. Carpet of wear sexual and raw materials of varieties about, also and tibetan rugs woven thickness about, more thick more wear 3, and back elastic: tibetan rugs in dynamic load contains Xia of thickness loss rate to said, is to tibetan rugs pressure must time Hou, removed pressure, measurement tibetan rugs and is not pressure Qian of thickness difference, with has give in to tibetan rugs surface layer fluff of back bomb ability, thick and difference more small of back elastic more good. Tested, resilient and so on: hair, BR/Acrylic, nylon, polypropylene. Of course, due to the different origin, different levels of technology, especially the production there of many modified, changes of this sort will have. 4, static: the tibetan rugs using a tibetan rugs surface resistance and static voltage charge and discharge, generally associated with conductive fiber itself. Current production of the chemical fiber rug are treated, on the use of no effect. 5, resistance to fire: fire resistance are important indicators of decoration materials, tibetan rugs, where the combustion time within 12 minutes, within the combustion area of 17.96 cm in diameter, fire retardancy is qualified. In contrast, poor combustion resistance of polypropylene fiber tibetan rugs, not many other tibetan rugs of resistance index of related. Of course, not including flammability resistance, also note the chemical fiber rug throw burning effect of Vim and harmful gas problems.
