A fabric woven from asbestos fibers. Due to its non flammability, it can remove dirt from cloth when burned, so it is often referred to as "fire washing cloth" or "fire alkane cloth" in early Chinese historical books. China started mining and utilizing asbestos earlier than other countries. There are records of fire washing cloth before the Han Dynasty, as stated in the "Liezi": "King Mu of Zhou launched a great expedition to the Western Rong, and the Western Rong presented the sword of Kun and the cloth of fire washing... The cloth of fire washing and washing must be thrown into the fire, the color of the cloth is fire, and the color of the cloth is dirt. When it comes to fire, it vibrates and solidifies like snow." By the Yuan Dynasty, China had a considerable level of technical expertise in asbestos mining, asbestos cloth weaving, and cleaning. There are many varieties and specifications of asbestos cloth, and the fabric structure includes plain weave, twill weave, and mountain shaped twill weave. The weight range of the fabric is 100-1000 grams per square meter, and the thickness is 0.4-2.5 millimeters. Asbestos cloth has excellent fire resistance and thermal insulation properties, and is commonly used as a fireproof and thermal insulation material for automobiles, airplanes, and trains. It has been applied in refrigeration equipment, welding worker protective clothing, theater screens, firefighting, steelmaking, and other fields.

Used

The main use of asbestos cloth is not only to manufacture various heat-resistant, anti-corrosion, acid resistant, alkali resistant and other materials, but also to use it as a chemical filter material and a diaphragm on electrolytic cells in the electrolysis industry. It is also used as an insulation material for boilers, gas bags, and machinery. In special occasions, it is used as a fire curtain and directly used as a wrapping and insulation material for various thermal equipment and heat conduction systems. Stone cotton cloth is interwoven with high-quality stone cotton yarn. Suitable for various thermal equipment and thermal insulation systems as insulation materials or processed into other asbestos products.
