In my Chinese dictionary the kang is described as a heatable brick bed. While this doesn't convey its comfort, it does describe this heated sleeping platform accurately. Kang, pronounced kahng and written ç is prevalent in northern China where the winters are fierce and long. What Exactly is the Kang? The kang is a platform made by bricks or other earthworks that takes up a large portion of the room. Inside the bricked platform is an area for heat carried from a furnace (traditionally coal). A flue from the channel leads to the outside for exhaust.
Glass wool products usually contain 95% to 96% inorganic material. Stone wool is made from volcanic rock, typically basalt or dolomite, an increasing proportion of which is recycled material in the form of briquettes.Mineral wool made from blast furnace slag (waste) is sometimes known as slag wool.here are two types of mineral wool product: glass wool insulation and stone wool insulation. Inorganic rock or slag are the main components (typically 98%) of stone wool. The remaining 2% organic content is generally a thermosetting resin binder (an adhesive) and a little oil.
The kind of sheep from which the wool is obtained, its physical condition, the part of the sheep from which the wool is obtained, and the finishing processes are some of the factors, which affect the properties of wool fabric.Composition: The chief constituent of these fibers is the protein substance called Keratin.Chemically these proteins contain 5 elements: carbon, hydrogen, oxygen, nitrogen, and sulfur. This is the only animal fiber, which contains sulfur in its composition. Strength: Wool is the weakest of all natural textile fibers.ool is the most resilient fiber because it has a natural crimp that helps it keep its shape. Wrinkles disappear when the garment or fabric is steamed. Good wool is very soft and resilient; poor wool is harsh. When buying a wool fabric, grasp a handful to determine its quality.
