In textile applications, the ammonia value and viscosity of aminosilicone fluid can affect its performance and scope of application. The following is the general situation of amino silicone oils with different ammonia values and viscosities in textile applications:
Ammonia value: Ammonia value refers to the content of amine groups in amino silicone oil, and is usually used to indicate the alkalinity of amino silicone oil. A higher ammonia value usually means that the amino silicone fluid is more alkaline and can provide better wetting and antistatic properties. In textile applications, aminosilicone oils with high ammonia values are often used in textiles with higher wetting requirements, such as sportswear, functional textiles, etc.
Viscosity: The viscosity of amino silicone oil determines its coating and penetration on textiles. The lower viscosity amino silicone oil has better permeability and can better penetrate into the textile fibers to provide softness and lubrication. Higher viscosity amino silicone oils are more suitable for surface coating and can form a thin lubricating film. Depending on the specific textile type and processing requirements, a suitable viscosity range can be selected.
It should be noted that the ammonia value and viscosity are only two aspects of the performance of amino silicone oil. In practical applications, other factors need to be comprehensively considered, such as the material of the textile, processing technology, required performance, etc. When selecting amino silicone oil, it is recommended to refer to the technical data and recommendations provided by the supplier, or conduct experimental verification to ensure the selection of the appropriate amino silicone oil type and specification.
