Chemical fiber oil

emulsifier

The choice of emulsifier is the key to the preparation of oil with good properties. The emulsifier should have good emulsification and stabilization ability of smoothing agent and antistatic agent. Therefore, the type of emulsifier should be determined according to the type of smoothing agent and antistatic agent selected. The selection of emulsifier can be based on the HLB value and combined with practical experience. It is generally required that the hydrophobicity of the emulsifier and the emulsified material should have a good affinity, and at the same time, it must maintain a large hydrophilicity, so as to prepare a good emulsion. The general emulsifier uses non-ionic surfactants, such as span-60, tween-60 and other polyether surfactants, which has good heat resistance, makes the fiber smoothing agent good and does not smoke

The characteristics of non-cohesion. The use of polyether in high-speed spinning and ultra-high-speed spinning oil can make the fiber quickly and evenly spread the oil on the surface of the oil at the speed of 3500 ~ 6200m/min.

Emulsifier dosage is generally 30%-50%.

Polyether belongs to the category of non-ionic surfactants and is an important component of textile additives and chemical fiber oil agents. According to different polymerization methods, polyethers can be divided into irregular polyethers and regular polyethers. Polyether surfactant generally has good heat resistance, can make fiber smoothing agent good, no condensation, no smoke characteristics. The use of polyether in high-speed spinning and ultra-high-speed spinning oils can make the fibers quickly and evenly spread the oil on the surface of the oil.

Balance regulator

Balance regulator is an indispensable component in the preparation of stable emulsion. It can make the surfactant components of various components in the oil miscible and give full play to the synergistic effect. Usually add higher fatty acids, higher fatty alcohols, polyols and so on.
