Description

Antistatic agent for cotton fabric
Technical Field
The invention discloses an antistatic agent for cotton fabrics, belonging to the technical field of textile materials.
Background
The fabric is easy to generate static electricity due to friction and induction in production, processing and use. The charge build-up phenomenon is more pronounced in synthetic fiber products where moisture regain is generally lower. The electrification phenomenon of the textile material in production can cause the phenomena of fiber winding or blockage of machine parts, semi-products or yarn hair and broken ends, unclear warp opening, uneven fabric folding and the like during weaving, and the smooth production is influenced; when the textile is used, the accumulation of electrostatic charges easily causes dust adhesion, and the clothing entangles limbs to generate the uncomfortable adhesion feeling; and can cause the pH value of blood to rise, the calcium content in the blood to decrease, the calcium content in urine to increase, the blood sugar to rise and the vitamin C to fall. The high static voltage may cause electric shock to a human body and cause damage to electronic components, even resulting in fire and explosion.
The antistatic agent is a general term for a substance used for suppressing the generation of static electricity on the surface of a material having excellent electrical insulating properties such as a synthetic resin or the like or for eliminating the accumulated static electricity. They play a role in the production, processing and use processes of synthetic fibers, and are particularly significant in preventing static electricity from generating and accumulating and overcoming the phenomenon that the fibers rub against each other to generate charges. The antistatic agent mainly refers to metal powder, inorganic substances such as carbon and the like, polysiloxane compounds, surfactants and the like. External antistatic agents are currently most used. It is used for surface spraying, dipping and coating in the production, processing and other processes of synthetic fiber. External antistatic agents are anionic, cationic, nonionic and amphoteric surfactants. The anionic antistatic agent has high heat stability, and is used mainly in the production and processing of synthetic fiber. It mainly comprises higher alcohol acid ester (salt), aliphatic sulfonate and higher acid phosphate. As the cation part of the counter ion, in addition to metal ions such as sodium and potassium, alkylol amine such as triethanolamine is used.
External antistatic agents are mostly surfactants, and they are poor in washing resistance and durability, and antistatic properties are substantially lost after processing.
