The difference between amino silicone oil and polyether silicone oil? What are the characteristics of each?
Amino silicone oil is a basic ingredient specially used in textile softening and finishing agents. It has the best adsorption, compatibility and easy emulsification. Using a mixer or homogenizer, aminosilicone oils are easily emulsified with appropriate surfactants into stable, transparent microemulsions. It can be used alone or combined with other silicones or organic softeners to form a special softening finishing agent. The block copolymer silicone oil for softening and finishing of various textiles should refer to polyether silicone oil.
Silicone oil with polyoxyethylene group or polyoxypropylene group, fatty alcohol polyoxyethylene polyoxypropylene ether group connected to the carbon atom of side chain is polyether silicone oil, which is to improve the use process of the first and second generation silicone softeners. It is a product developed due to the unsatisfactory shear stability of silicone emulsion and the poor hygroscopicity of the finished fabric.
It can be prepared by addition reaction of hydrogen-containing silicone oil and unsaturated polyether under the catalysis of platinum catalyst, or by the ring-opening reaction of epoxy silicone oil and polyether, or the reaction between alcoholic hydroxyl modified silicone oil and bifunctional carboxylic acid and polyether. prepared by esterification. After the hydrophilic polyether group is introduced into the side chain, the hydrophilicity of the silicone oil increases, and even completely converts from hydrophobicity to water-solubility. Therefore, the problem of demulsification and oil floating will not occur during the use of polyether modified silicone oil.
Endly, the introduction of polyether group also increases the hygroscopicity, antistatic property and easy decontamination of the finished fiber or fabric, so polyether silicone oil is used more in cosmetics and shampoo products. However, the self-crosslinking film-forming ability of polyether silicone oil and the binding ability with fibers are weak. This problem can be solved if some epoxy groups are introduced or retained on the main chain of the silicone oil during the preparation process. In terms of performance, it not only has all the advantages of polyether silicone oil, but also the finished fabric is softer, wrinkle-resistant, washable, and has a strong wool feel.
Therefore, polyether/epoxy silicone oil is a kind of active silicone softener with the largest amount and the best effect before the successful development of cationic amino silicone softener.
