NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to advancing textile finishing through innovative chemical solutions. Amino silicone oil, a key component for softness and smoothness, becomes even more powerful when strategically blended with other chemical agents. This article explores various blending techniques to enhance textile properties, offering a competitive edge to manufacturers.

1. Blending for Durable Softening and Smoothing: While amino silicone oil provides excellent initial softness, its durability can sometimes be a concern. Blending amino silicone oil with hydrogen-containing silicone oil allows for a cross-linking reaction on the fiber surface during the finishing process. The Si-H groups in the hydrogen-containing silicone oil react with the amino or hydroxyl groups of the amino silicone oil, forming a robust, cross-linked film. This significantly improves adhesion and durability, while also enhancing smoothness and elasticity. Adding αω-dihydroxy polydimethylsiloxane can further optimize this effect.

2. Blending for Deep Color Effect: For synthetic fibers like polyester, achieving deep and vibrant colors can be challenging. Blending amino silicone oil softeners with polyethyl silicate can significantly enhance the deep color effect of dyed fabrics. Polyethyl silicate acts as a cross-linking agent, improving light and weather fastness of dyes. When blending, it's crucial to maintain the right ratio (typically 0.1-5 parts of polyethyl silicate per 100 parts of amino silicone oil) to avoid compromising the softness. Surfactant choice is also key; non-ionic surfactants with an HLB of 13-15 are recommended for emulsion stability and optimal color depth.

3. Blending for Shrink Resistance: Wool and other animal fibers are prone to felting and shrinkage. Cross-linkable amino silicone emulsions can be blended with silica sol or methyltrimethoxysilane to create effective shrink-resistant softening agents. The amino silicone oil provides softness and lubrication, while the silica sol or silane forms a protective, slightly cross-linked network on the fiber surface, significantly reducing shrinkage during washing. The composition of amino silicone oil, including its reactive groups, can be tailored to adjust the film's hardness.

4. Blending for Wrinkle Resistance without Formaldehyde: Traditional wrinkle-resistant finishing agents often release formaldehyde, posing health risks. An alternative involves blending propoxy-modified polyorganosiloxane with amino silicone oil. This combination forms a cured film on the fiber surface without needing catalysts. It imparts a soft, smooth style, excellent wrinkle resistance, and good washing durability, all while being formaldehyde-free. This offers a safer and more sustainable finishing option.
