Do you know that all kinds of surfactants have antistatic agents

Static electricity can make the tow disperse and produce filament and broken ends, and it is not easy to wind. Using the ion characteristics and hygroscopicity of antistatic agent, it can effectively prevent the accumulation of static electricity. At the same time, the adsorption and orientation of antistatic agent are also helpful to eliminate static electricity.

Although all kinds of surfactants have antistatic agents, quaternary ammonium salt is corrosive, and the price of amino acid amphoteric antistatic agents is too high. But in the compounding of oil agent, antistatic agent must meet the compounding requirements of smooth agent, and lauryl alcohol phosphophenol ester has excellent balance, so it is still widely used until now. In addition, polyethylene glycol ether phosphate can change its hydrophilicity and lipophilicity due to the control of molecular weight, which is easy to achieve the purpose of emulsification and dispersion, so it will be widely used in the future. A kind of

In order to reduce friction, natural mineral oil, vegetable oil, animal oil, synthetic ester (pentaerythritol ester, sorbitan ester, fatty alcohol ester, etc.), ether (block or random polyether composed of oxyethane, oxypropane, oxybutane, etc.) are commonly used. A kind of

The viscosity of synthetic fatty ester is small, boiling point is low, melting point is high, wear is large, oxidation stability is poor, temperature sensitivity of viscosity is also large, so it is seldom used.

The polybasic fatty alcohol ester has low volatility and freezing point, low temperature sensitivity of viscosity, excellent thermal stability and wear resistance, good solubility and compatibility with licking additive, easy to mix with other oil agents, small abrasion to metal, stable hydrolysis and non-toxic. Polyol fatty acid ester has good thermal stability and oxidation resistance, so it is often used as a smooth component of oil agent. A kind of

The smoothness, film strength and clustering of polyether synthetic lubricants are higher than those of lipids, and they have the advantages of antistatic, softness and hygroscopicity, but the heat resistance is slightly worse than esters, so the direction of technological progress will be to develop polyether esters, dialkyl polyether, phosphorus containing polyether and polyether which is easy to degrade, etc. A kind of

The oil is added to the surface of the fiber in the form of emulsion, and at the same time it is easy to absorb after spinning. So the emulsifier is the key. It is easy to meet the HLB requirements of different smoothers and antistatic agents, especially alkanol polyether, alkylphenol polyether, sorbitol fatty acid polyether, polyethylene glycol fatty acid ester, etc. The combination of two or more emulsifiers can achieve better emulsification effect. In addition, the development of functional polyether, which makes polyether have the structure of smoothness, antistatic and emulsification, has become the development trend.
