Analysis of Flame Retardant Forms of Flame Retardant Fabrics for Fire Fighting Clothing

At present, fire-retardant fabrics for domestic occupational fire-fighting clothing are mainly divided into permanent fire-retardant fabrics and post-finished fire-retardant fabrics. However, both permanent flame-retardant fabrics and post-finish flame-retardant fabrics of occupational fire-fighting clothing have flame-retardant properties, but there is a big difference between the two. The permanent flame-retardant treatment mainly improves the thermal stability of the fiber-forming polymer and the flame-retardant modification of the raw silk to make the fabric have a permanent flame-retardant effect; and the post-finish flame-retardant fabric is mainly used in the finishing process of textiles. The fabric is surface treated to make the fabric flame-retardant.

Generally speaking, permanent flame-retardant fabrics of occupational fire-fighting clothing rely on the flame-retardant properties of textile fiber raw materials to achieve flame-retardant effects. The post-processing of the flame-retardant effect of permanent occupational fire-fighting clothing focuses more on two aspects: one is Improve the thermal stability of fiber-forming fabrics, and improve the flame-retardant effect of flame-retardant fabrics through covering layer test and chemical reaction test; the second is to improve the heat absorption and catalytic dehydration properties of flame-retardant raw silk.

The flame-retardant fabrics of professional fire-fighting clothing are mainly used to achieve the flame-retardant effect of textiles through padding and baking method, organic solvent method, coating method, etc., and its initial flame-retardant performance is compared with permanent flame-retardant fabrics. There is not much difference, but because most flame-retardant fibers or fabrics have certain deficiencies in water repellency, oil repellency, and resistance to static electricity, the use of flame-retardant fibers and high-performance fibers for blending and interweaving is more suitable and satisfied with the flame retardant of professional fire-fighting clothing need.

Comprehensive analysis, because the flame retardant of the fire-retardant fabric after finishing is attached to the surface of the fabric, it has not penetrated into the yarn. After washing with water or the increase in use time, its flame-retardant effect will gradually disappear, so it is permanent flame-retardant The development prospects of fabrics are being discussed more and more.
