Reinforced soil particles

Is the tradename for wollastonite. It is available in three grades varying in particle size. An acicular calcium silicate, it is used as a filler and reinforcing agent in plastics, cement, wallboard, soil conditioner and in casting plasters. 

Synthetic fibres take a static charge because they are non-conductive and only absorb small quantities of water. This effect is reinforced by low air humidity, particularly in winter, and soiling may be increased. Antistatic finishings reduce the high electrical resistance of fibres. These consist of hydrophilic surface active polar compounds (tensids), carbon particles, electrically guiding polymers or salts. Textiles may also be made antistatic by incorporating metallic or metallised fibres or conductive carbon fibres which are coated with polyamide.
