1. The direct relationship between the amount of flame retardant added and the flame retardant effect
The main function of flame retardants is to slow down or prevent the combustion process by chemical or physical means, thereby improving the fire resistance level of the material. In the production of curtain fabrics, the amount of flame retardant added directly affects its flame retardant properties. Generally speaking, within a certain range, as the amount of flame retardant added increases, the flame retardant efficiency of curtain fabrics shows an upward trend. This is because more flame retardants can more effectively form a protective layer, isolate oxygen, inhibit heat transfer and the generation of combustible gases, thereby delaying the spread of fire.
However, this positive correlation does not continue indefinitely. When the amount of flame retardant added exceeds a certain critical value, the improvement in flame retardant efficiency will gradually decrease, and there may even be a "saturation effect", that is, further increasing the flame retardant content will have little effect on improving flame retardant properties. In addition, excessive flame retardant content may also bring other problems.
2. Negative impact of excessive flame retardants on the performance of curtain fabrics
Changes in hand feel: The addition of flame retardants will change the fiber structure of curtain fabrics. Excessive flame retardants often cause the fabric to feel harder and lose its original softness and comfort. This not only affects the user experience, but may also reduce consumer satisfaction with the product.
Changes in color: Certain flame retardants may affect the color fixation of dyes during the process of combining with fibers, causing the color of curtain fabrics to fade or have color differences. Uneven or changing color is undoubtedly a significant defect for home decoration that pursues beauty.
Decrease in strength: Excessive use of flame retardants may also weaken the mechanical strength of curtain fabrics, such as tensile strength and tear strength. This reduces the durability of curtain fabrics and increases the risk of breakage during daily use.
3. Finding the best balance point
Given the dual effects of the amount of flame retardant added on the flame retardant effect and comprehensive performance of curtain fabrics, it is particularly important to find a balance point that can ensure good flame retardant performance without sacrificing other key performances. This requires manufacturers to conduct a large number of experiments and optimizations during the research and development stage, by adjusting the type of flame retardants, the amount added and the production process, in order to achieve the best balance between flame retardant effect and properties such as feel, color and strength.
