It is the active component of a number of abrasive cleaner sponges, notably the Magic Eraser. It is also used as thermal insulation and as a soundproofing material.
One of the most common devices for measuring temperature is the glass thermometer. This consists of a glass tube filled with mercury or some other liquid, which acts as the working fluid. Temperature increase causes the fluid to expand, so the temperature can be determined by measuring the volume of the fluid.
Microfiber fabric is lightweight, durable, and somewhat water repellent, so it makes a good substitute. Another advantage of microfiber fabric (compared to leather) is that it can be coated with various finishes and can be treated with antibacterial chemicals. Fabric can also be printed with various designs, embroidered with colored thread, and ...
Separated columns are often a problem in both alcohol and mercury thermometers, and they can make a temperature reading inaccurate. The precision or resolution of a thermometer is simply to what fraction of a degree it is possible to make a reading. For high temperature work it may only be possible to measure to the nearest 10 °C or more.
Stains will be on the fabrics when the fabrics are unevenly distributed, which is the disadvantage of using the tumble dryer. [4] A reservoir for storing a fabric treatment composition is a device that the tumble dryer provides for different drying cycles. [4] The nebulizer system is used in fabric treatment devices. [11]

Medical devices are commonly made in whole or part from fibers. A medical device is defined as any device intended for medical purposes. It could be a machine, a reagent for use in the lab, software, an appliance, an instrument, or an implant. [32] For medical use, fiber selection is based on certain criteria of intended use.
