I. Differences in Core Form and Processing Adaptability
Amino silicone oil, as a basic raw material, exists as a high-viscosity, translucent or light yellow viscous liquid. The amino functional groups in its molecular chain give it the ability to directly bond with the active functional groups on the fiber surface. This characteristic means that in processes such as padding and spraying, it requires high-temperature cross-linking to form a protective film, but when used alone, it is prone to uneven penetration. For example, high-amino-value amino silicone oil can significantly improve fabric softness, but its high molecular polarity makes emulsification difficult, requiring the addition of emulsifiers for stable dispersion.

Amino silicone oil emulsion, on the other hand, uses surfactants to convert amino silicone oil into a microemulsion with a particle size of less than 0.15 μm, forming a thermodynamically stable dispersion system. This form overcomes the limitations of direct use; its small particle size increases surface adsorption by more than 30%, and its permeability is enhanced. Zhejiang Transfar's TF-463A block polyether amino-modified silicone oil emulsion achieves self-emulsification through molecular structure design, solving the industry pain points of traditional emulsions such as easy demulsification and roller sticking, and maintaining stable performance even in recycled wastewater.

II. Comparison of Application Efficiency and Process Costs
In the softening process, amino silicone oil emulsion demonstrates significant advantages. Experimental data shows that when treating fabrics at a concentration of 15 g/L, the emulsion system can increase fabric breaking strength by 12%, increase the wrinkle recovery angle by 25°, and reduce the whiteness loss rate by 40% compared to direct use. This is due to the evenly distributed amino silicone oil molecules in the emulsion forming a regular arrangement, and the adsorption effect of the microemulsion's charge (such as cationic type) with the negative charge of the fiber enhances the finishing effect.

From a process cost perspective, the emulsion system can reduce the amount of amino silicone oil used by 30%, and eliminates the high-temperature cross-linking step, reducing energy consumption by 20%. Taking a company that produces 50 million meters of fabric annually as an example, using the emulsion system can save approximately 800,000 yuan in raw material costs annually, while also reducing wastewater treatment costs. Furthermore, the emulsion system requires less sophisticated equipment; stable production can be achieved with a standard padding machine, whereas direct application requires specialized high-temperature setting equipment, increasing equipment investment by more than 50%.
