Is the flame retardant treatment process of textile flame retardant complicated?

Apr 11, 2018

Flame retardant is more complex for flame retardant textile fabrics.

1. Temporary flame retardant:After the molding of the machine rolling, the flame retardant can be set.The advantage is that the flame retardant is universal, which is suitable for the fabric of various kinds of fibers as well as the blended fabric of two or more fibers.Defect is not washable, flame retardants containing more than salt dosage is too large to produce salting-out phenomenon, and might be in contact when using the metal, leather and so on to cause corrosion (such as sofa leather flame retardant fabric corrosion and nails, and the corrosion will cutting bed and sewing equipment)

2. Durability fire retardant:Commonly used in polyester flame retardant and cotton flame retardant.The technology of polyester flame retardant and temporary flame retardant is close, but the setting temperature is higher and the setting time is longer.The advantage is the washing resistance, the disadvantage is that the cloth will change color when the flame retardant finishing.Cotton flame retardant is more complex, there are several kinds of processes (such as proban process and CP process), which requires that it be baked for 3~5 minutes.Formaldehyde residues, fabric discoloration and loss of strength.Polyester flame retardant only has flame retardant effect on polyester, cotton flame retardant only has the flame retardant effect to cellulose fiber, it is difficult to adapt to blend products.
