In-depth study on the internal composition of flame-retardant cloth (pure dry goods)

Flame-retardant non-woven fabrics have always been a type of product with a relatively high usage rate in the market. But to achieve good flame retardancy, not every company can do it. Next, let's explore the in-depth study of the internal composition of the flame retardant non-woven fabric. To determine its current level of flame retardancy or arc protection value without destroying the flame or arc flash test of the clothing, there is really no way to test the clothing. All these test methods are destructive and it is very difficult to determine whether the protective device is damaged with the Fu200bu200bu200bu200bu200bu200b There are some ways to test it. Dilution effect, cooling effect, reaction in the condensed phase, reaction in the gas phase. This is done in four different modes of action. Flame retardants are chemicals that interfere with one or several steps in the combustion process. The other is to use strong flame retardants. This reaction is triggered by the heat of the fire and the amount of time the fabric is exposed to the fire. In the event of a fire, chemical-related fabrics rely on chemical reactions to extinguish the flame. Chemical additives on the fiber or treatment on the fabric are used to provide a certain degree of flame retardancy. The other main category is flame retardant treated (FRT) fabrics. These materials are made flame retardant by the application of flame retardant chemicals. It is inherently flame-retardant fiber, and the protection is built into the fiber itself and cannot be worn off or washed out. Inherently flame retardant fibers are materials that have flame retardancy built into their chemical structure. The actual structure of the fiber itself is not combustible. The topical treatment can be used with thermoplastics, thermosetting plastics and natural fibers, and the additive type is useful with thermoplastics. Additives (mechanically blended flame retardant chemistry and polymer before extrusion) and local (coated fiber or fabric with flame retardant chemistry). Flame retardancy can be achieved in two ways. The above is the detailed description of the in-depth study on the internal composition of flame retardant non-woven fabrics.
