Polyether modified silicone oil and amino silicone oil: functional complementarity of hydrophilicity and flexibility
Comparison of Chemical Modification Strategies:


Polyether modified silicone oil: Introducing hydrophilic groups through polyether segments to form a amphiphilic structure that combines water solubility and lubricity, with a contact angle that can be reduced from 110 ° to 30 °.
Amino silicone oil: Introducing amino groups into the side chains or end groups endows the fabric with strong adsorption and flexibility, and the ammonia value (mmol/g) directly affects the treatment effect.
Differences in application in the textile field:
Polyether modified silicone oil: as polyurethane foam homogenizer, the density of foam is reduced by 30%; In hydrophilic finishing of fabrics, the moisture absorption of cotton fabrics can be increased by 5 times.
Amino silicone oil: occupies 80% of the textile softener market share. Single end products reduce fabric bending stiffness by 60%, while double end products can improve wrinkle resistance by 40%.
Performance balance point: Polyether modified silicone oil achieves hydrophilic oleophilic balance by adjusting the EO/PO ratio (such as 1:1, 2:1); Amino silicone oil optimizes fabric feel and color fastness by adjusting the ratio of primary amino (- NH2) to secondary amino (- NHCH3).
