Abstract

The invention discloses a formaldehyde-free elastic silicone resin dispersion. The formaldehyde-free elastic silicone resin dispersion comprises 10-90wt% of elastic silicone resin, 10-30wt% of a nonionic emulsifier, and the balance of water. The dispersion contains no formaldehyde, and makes textiles have extremely good crease resistance and washing fastness.

Description

technical field [0001] The present invention relates to a dispersion, in particular to a formaldehyde-free elastic silicone resin dispersion. Background technique [0002] With the improvement of people's living standards, people have higher and higher requirements for the functionality of fabrics, such as non-ironing, antibacterial, soft, flame-retardant or waterproof functions. Textiles, especially cotton and linen fabrics, are prone to wrinkles after frequent use or after washing and drying. In order to impart anti-wrinkle properties to fabrics, physical or chemical methods are usually used. The most commonly used physical method is the ironing method, but the ironing method is time-consuming and labor-intensive, so people hope to achieve the purpose of non-ironing or washable wear through chemical methods. One widely used no-iron finishing chemistry is the N-methylol-based 2D resins, which are considered to be the most effective and the least expensive in long-term app...
