Discussion on multi-functional finishing technology of Teflon flame-retardant cloth
Classification:
flame retardant fabric
With the continuous changes in the social environment, consumers’ living standards are improving day by day, and their needs are becoming more and more diverse. Textile materials and clothing fabrics are required to be environmentally friendly, comfortable and multi-functional, especially high-end men’s and women’s windbreakers, sportswear, casual wear and Protective work clothes put forward higher requirements for water repellency, oil repellency and anti-fouling. Therefore, in order to adapt to market demand, our factory has conducted many tests on the finishing ofTeflon flame-retardant cloth, and has now produced Teflon that has passed the test and is satisfactory to customers. Flame retardant fabric finishing products.
The working principle of Teflon flame retardant cloth finishing
Fabrics treated with Teflon can form a molecular barrier on the fiber surface. After being baked at high temperature, a thin film with very small surface tension can be formed. Due to its low surface energy, it can block the penetration of water, oil and dirt. By adhering and penetrating, flame-retardant cloth water and oil contaminants appear as droplets on the surface of the fabric and are easily removed, forming a better waterproof and anti-oil effect. At the same time, due to high-temperature baking during processing, the Teflon finishing agent is absorbed into the fiber. The film formed on the surface can be firmly combined with the fiber. At the same time, due to its water and oil repellency, water and oil cannot decompose this polymer, so Teflon-finished fabrics have good washing and dry cleaning fastness.

2 Finishing agent selectionFlame-retardant clothAfter many sample tests and comparisons, we selected OlephobolC, which has better water-repellent, oil-repellent and anti-fouling effects, as the finishing agent .
Properties of finishing agent OlephobolC:
Chemical composition: perfluoropolymer emulsion, containing synergistic ingredients
Ionic properties: cation
pH value: 3.3-5.0
Appearance: milky white to slightly brown emulsion, low viscosity
Stability: Stable at 20°C in a closed container. Temperatures lower than -10°C or higher than 40°C will have an impact on this product.
Application method: padding method
Routine process: padding-drying-baking
