How to Select Amino Silicone Oil?
It's necessary to analyze specific situations. As we all know, amino silicone oil can be used for fabrics. In fact, when amino silicone oil is applied to different fabrics, the ammonia value requirements are also different. Therefore, we need to analyze specific situations. Here, Xinjia will tell you which kind of fabric should be paired with amino silicone oil of what ammonia value.

1. For cotton and blended knitted fabrics and woven fabrics, which mainly focus on a soft hand feel, you can mainly choose amino silicone oil with an ammonia value of 0.6.
2. For polyester fabrics, which mainly focus on a smooth hand feel, you can choose amino silicone oil with an ammonia value of 0.3.
3. For silk knitted fabrics and woven fabrics, which mainly focus on a smooth hand feel and have relatively high requirements for luster, you can mainly choose amino silicone oil with an ammonia value of 0.3 and compound it with a smoothing agent to increase the luster.
4. For some blended fabrics that require a comprehensive hand feel combining softness, smoothness and elasticity with little change in color and luster, you can choose the compound product of amino silicone oil with ammonia values of 0.6 and 0.3. Some varieties can be compounded with a smoothing agent to increase elasticity and luster.
5. For sweaters and cashmere fabrics, which have a higher comprehensive hand feel than wool fabrics, you can choose high-concentration compound products.
6. For nylon socks, which mainly focus on a smooth hand feel, you can choose high-elasticity amino silicone oil.
7. For nylon Raschel blankets, acrylic and blended woolen yarns, which mainly focus on softness and have high requirements for elasticity, you can choose amino silicone oil with an ammonia value of 0.6 to meet the requirements for elasticity at the same time.
8. For hemp fabrics (such as flax and ramie), which mainly focus on smoothness, you can mainly choose amino silicone oil with an ammonia value of 0.3.
9. For silk and rayon fabrics, which mainly focus on a soft hand feel, you can choose amino silicone oil with an ammonia value of 0.6.
10. For alkali-reduced fabrics, which are mainly to improve the hydrophilicity of the fabric, you can choose polyether-modified silicone oil (CGF). It is made by the hydrosilylation reaction of methyl hydrogen-containing silicone oil with polyethers such as polyethylene glycol and polypropylene glycol with unsaturated bonds at the terminals. However, its softness is relatively poor. The new polyether-modified silicone oil introduces reactive epoxy groups and so on into the siloxane chain, improving the hand feel and durability of the fabric.

Different fabrics have different requirements for the hand feel. Therefore, we should choose silicone oil with different ammonia values according to specific situations so as to ensure the ideal hand feel of each kind of fabric.
