Core Type: Amino-Modified Silicone Softeners
Amino-modified silicone softeners are currently the most widely used products for enhancing abrasion resistance in the textile industry, often referred to as the "king of softeners." By introducing active groups—such as aminopropyl—onto the side chains or terminal groups of the polysiloxane, they form a continuous, durable lubricating protective film on the fiber surface. This significantly reduces the coefficient of friction between fibers and between fibers and external abrasive surfaces, thereby markedly improving the fabric's abrasion resistance.
Fabrics treated with this type of softener not only acquire a full, smooth, and soft hand-feel but also effectively resist fuzzing and pilling caused by repeated friction. Additionally, they exhibit improved tear strength and elongation properties. These softeners are widely used in the finishing processes for various textiles, including cotton, linen, wool, and chemical fibers.

Advanced/Optimized Type: Amino-Polyether Block-Modified Silicone Softeners
Representing a mainstream product among fourth-generation silicone softeners, amino-polyether block-modified silicone softeners offer further enhancements in abrasion resistance. While utilizing aminopropyl groups to ensure strong fiber bonding, they incorporate hydrophilic polyether segments. This design retains the excellent lubricating and abrasion-resistant qualities of traditional amino silicone oils while overcoming common drawbacks such as susceptibility to yellowing and excessive hydrophobicity.
Application data indicates that linen fabrics treated with this type of product retain 89% of their softness after 50 wash cycles and show a reduction in frictional wear of over 40%. Furthermore, they impart excellent wrinkle recovery properties to the fabric. Widely used in high-end non-iron shirts and durable outdoor fabrics, this class of softeners is an ideal choice for balancing abrasion resistance, hydrophilicity, and wash durability.
