Silicone oil is widely used in the textile industry to enhance the softness, smoothness, and durability of fabrics. Common types of silicone oil include traditional silicone oil, amino silicone oil, and polyurethane non silicone oil. These silicone oils have significant differences in performance and application effects.

Traditional silicone oil
Traditional silicone oil is mainly composed of siloxane polymers, which have excellent softness and smoothness, but poor durability and are prone to loss during washing. For example, in the post-processing of wool fabrics, although traditional silicone oil can quickly improve the hand feel, the effect will significantly decrease after multiple washes.

amino silicone oil
Amino silicone oil is a modified silicone oil with higher durability and affinity. It enhances the anti pilling and wear resistance of the fabric through the binding of amino groups to the fiber surface. However, amino silicone oil has poor environmental performance and may have a certain impact on the environment.

Polyurethane non silicone oil
Polyurethane non silicone oil combines the advantages of polyurethane and siloxane, not only possessing extremely high flexibility and smoothness, but also significantly improving durability and environmental friendliness. For example, a high-end woolen sweater manufacturer introduced a finishing solution containing 4% polyurethane non silicone oil during the production process. The results showed that the treated woolen sweaters not only had a soft hand feel, but also significantly enhanced anti pilling ability and extended service life.

practical cases
In the application of silk fabrics, polyurethane non silicone oil performs well. A silk manufacturer has adopted a post-treatment process containing 2.5% polyurethane non silicone oil on its high-end scarf product line. Customer feedback shows that the new product has significantly improved flexibility and wrinkle resistance, while maintaining good gloss. In contrast, silk fabrics treated with traditional silicone oil are prone to wrinkling and difficult to clean issues.

In summary, polyurethane non silicone oil is gradually replacing traditional silicone oil and becoming the preferred material in the textile industry due to its excellent performance and environmental friendliness.
