In finishing fabric, silicone oil softener application is now one of the main practices to improve fabric texture and wearing comfort. For different materials such as cotton, polyester, nylon, etc., the concentration of the selected silicone oil has direct effects on fabric softness, hydrophilicity, stability, and durability of the product. As a leading textile auxiliaries manufacturer, BLUELAKECHEM provides a range of high-performance silicone oils to textile producers globally and helps customers accurately select the correct silicone oil density parameters according to process needs and fabric types to achieve the best finishing effect.
What is silicone oil density?
Silicone oil density typically refers to its mass per unit volume, and the unit applied is g/cm³. It is one of the physical properties used to determine the weight of silicone oil. Not only does it affect the degree of adhesion of silicone oil on the fabric, but it also has a direct correlation with its dispersion property, soft touch, smoothness and emulsion stability.
- Low-density silicone oil: good fluidity, easy penetration, appropriate for thin fabrics or applications requiring enhanced smoothness.
- High-density silicone oil: longer molecular chains or more complex structures, stronger softness, suitable for heavy fabrics or finishing needs that pursue a fuller feel
Using inappropriate silicone oil will affect the overall performance of the fabric:
- Too high density: may cause a “greasy” feel and poor permeability.
- Too low density: may result in insufficient softness and the effect of fabric treatment is not long-lasting.
Therefore, the rational selection of silicone oil density and scientific matching with fabric types, functional requirements, and processing methods are key steps for garment factories and dyeing and finishing factories to improve product quality and processing efficiency.
Five major effects of silicone oil density on textile performance
Hand feel control: The higher the density, the more obvious the smoothness; low density is more skin-friendly and natural, suitable for close-fitting clothing.
Penetration and uniformity: Low-density silicone oil makes it easier to penetrate the fiber structure and is suitable for fibers or lightweight fabrics.
Emulsion stability: Dầu silicon with moderate density is conducive to the formation of a stable emulsion system and improves the shear resistance and storage performance of additives in the process.
Color light influence: High-density silicone oil may cause color differences on dark fabrics, while hydrophilic silicone oil can reduce color light changes.
Process compatibility: Silicone oils of different densities have different degrees of adaptability to finishing processes such as color fixation and softening. BLUELAKECHEM can provide silicone oil customized solutions to adapt to automated production lines
Application differences of different types of silicone oil density
Dầu silicon amino
- Density characteristics: medium to high
- Recommended use: Suitable for cotton and polyester blended fabrics that require high softness and smooth feel
- Product advantages: strong reactivity, firm bonding with fabrics, and long-lasting effect after finishing
Dầu silicon ưa nước
- Density characteristics: relatively low
- Recommended use: products that need to take into account both hygroscopicity and softness, such as baby clothing and sports fabrics
- Product advantages: soft and does not affect water absorption, green and environmentally friendly, and meets OEKO-TEX standards
Block Silicone Oil
- Density characteristics: medium and low density, balanced structure
- Recommended use: finishing of chemical fiber fabrics such as silk, polyester and nylon
- Product advantages: high-temperature shear resistance, good emulsion stability, giving fabrics good elasticity and resilience

Phần kết luận
The density of silicone oil is not just a parameter, it directly affects the feel, stability, washability and overall appearance of textiles. In the field of textile auxiliaries, there is no universal silicone oil, only the most suitable density and structure-matching solution. By understanding the density differences of different types of silicone oil, you can more scientifically select silicone oil products with suitable density, which can significantly optimize the quality of fabric finishing and increase product added value.
