Flame retardant textile: What are Inherent Fabrics and Fibers?

Inherent fabrics and fibers do not need to be chemically treated.  The flame resistant properties are an essential characteristic of the fiber chemistry.  Once again these fibers are flame resistant fibers, but from creation of the fibers.  Both inherent fabrics and fibers cannot lose their flame resistant properties from normal wear or laundering.  The garment will keep its flame resistant characteristics throughout its life.

Modacrylic fibers are the most popular inherent fibers.  They are primarily used in blends with other inherent flame resistant fibers.  The modacrylic fibers are often combined with various percentages of lyocell, para-aramid or polyamide imide fibers.  These combinations make a durable fabric that meets NFPA 70E CAT2 and NFPA 2112 standards.  Another popular inherent fiber is NOMEX.  In clothing applications, NOMEX comes as a stand alone fiber or often in a blend with KEVLAR.

Inherent fabrics and fibers are found in petrochemical, electrical and utility industries.  Another popular application is firefighter station wear and turn out gear.  Most inherent fabrics and fibers are not recommended for use in welding operations or around molten substances.  Caring for inherent fabrics and fibers is the same as the treated types.  Soft water is recommended as hard water contains mineral salts that can leave insoluble deposits on the fabric.  These deposits could negate the flame resistant properties of the garment.  Chlorine bleach is also not recommended as it will weaken the fabric.

This information is provided by yulong safety, a leader in the flame resistant garment industry.  This is also not necessarily an endorsement of yulong safety.  There are other brands that manufacture high-quality flame resistant garments as well.  The most important thing to understand is what fabrics and fibers build the garments that keep you safe while on the job.  If you would like to schedule a consultation, let us know.  We can make it easier for you to put your team in the proper safety apparel.
