Research progress of antistatic coating on fibers


Synthetic fiber yarns or fabrics are susceptible to static electricity due to friction during processing or use.Electrostatic fibers tend to adsorb dust and cause contamination. During processing, the attraction or repulsion of electric charges can make processing difficult.During the spinning process, static electricity will cause poor cohesion between fibers, easy to entangle and break, which will affect the smooth progress of spinning. In the dyeing and finishing process, the fabric will be easily adsorbed on the metal body after being dried with static electricity, causing the fabric to roll on the drum wrap; the static electricity generated during the wearing of clothes is easy to get rid of the body and uncomfortable to wear.When the accumulated static electricity is higher than 500v, sparks may be generated due to discharge, causing a fire. When the temperature is higher than 8000v, a hit phenomenon may occur.

Antistatic coating are chemical auxiliaries that are applied to the surface of fibers or fabrics to increase the hydrophilicity of their surface to prevent static buildup on the fibers.The use of a hydrophilic substance to treat hydrophobic synthetic fibers can improve the hygroscopicity of the fiber surface, and the formation of an electrically conductive ion layer on the surface of the fiber greatly reduces the surface specific resistance of the fiber, thereby achieving an antistatic effect. Antistatic coating can be classified into temporary Antistatic coating and durable antistatic coatings.The antistatic coating for spinning and spinning for synthetic fibers is mostly a temporary antistatic coating, and most of the durable antistatic agents for finishing the fabric are durable antistatic agents.At present, the temporary antistatic coatings used in the industry are mainly some surfactants. Since ionic surfactants can directly use their own ionic conductivity to eliminate static electricity, many applications are currently in use.
