Fire Retardant Reflective Fabric Durability of
Proban is a flame retardant auxiliaries is also a flame reta flame retardant propertiesrdant process, the use of this process flame retardant fabric has many advantages are widely used.
Proban flame retardant process originated in the United Kingdom Aowei company, the main component is tetramethylol phosphate (THPC) and amide low molecular pre-shrinkage. After the fabric is impregnated with the flame retardant, the preformed body formed by THPC and amide penetrates into the amorphous region and the gap of the fiber, and then NH3 is crosslinked with the hydroxymethyl group in the pre-shrinking form during ammonia fumigation and forms in the fiber The flame retardant polymer is oxidized to stabilize. Therefore, the Proban method of dealing with the fabric after the soft, strong loss of dawn, basically keep the fabric comfortable horse and durability.
Proban This is a water-soluble flame retardant easily penetrate into the fiber, after the ammonia chemical reaction into a polymer after the formation of a permanent cross-linking, it has a durable flame retardant properties, and the flame retardant properties Does not decrease with the increase in the number of washing times. At the same time this flame retardant finishing does not change the original properties of fabric fibers, thus maintaining the original fabric performance. This flame retardant cloth with the fire will be charred, from the fire self-extinguishing, effective to prevent the spread of the characteristics of the flame, made of protective clothing can be effectively prevented from causing damage to the human body, the human body to provide effective security protection.
The development of PROBAN makes the fabric made of natural fibers have reliable flame-retardant properties and good durability, and can be applied to modern daily life and professional working environment.
The world as a result of flammable fabric countless fire, the tragedy of the fire simply can not describe the words, how can we reduce the occurrence of this tragedy? Flame-retardant fabrics have received close attention from all over the world. Especially for the performance of flame-retardant fabric textiles, standards and environmental aspects is more stringent requirements. There are two methods used in China to evaluate fabrics for flame retardant fabric performance.
Method 1: After flame retardant finishing flame retardant fabric according to the provisions of the method of contact with the flame, within a specified time the time of flame burning and flammable burning the shorter the time the lower the degree of damage, then the fabric The better the flame-retardant properties, while in the case of good flame-retardant properties of the human body and the environment is not harmful substances that the quality of the flame retardant cloth the better; the longer the burning time, the greater the degree of damage, then the flame retardant performance is not Well, there are harmful substances generated that the quality of flame retardant fabric is very poor.
Method two: through the fabric combustion is the oxygen index (LOI) to judge. In theory, the textile material oxygen index in 21% (natural air concentration is 21%), the textile products are self-extinguishing. According to the size of the anodic index, the fabric is usually divided into flammable (LOI less than 20%), flammable (LOI equal to 20% - 26%), flame retardant (LOI equal to 26% - 34%) and otherwise (LOI> 35%) four grades.
