Which fabric finish helps make fabric resistant to fire?

The fabric finish that helps make fabric resistant to fire is flame-retardant. This type of finish is specifically treated to reduce flammability and slow down the spread of flames when the material is exposed to fire. By chemically altering the fibers, flame-retardant finishes can help prevent the fabric from catching fire easily and can provide additional time for individuals to escape in the event of a fire.

Other finishes, such as stain-resistant and water-repellent, serve different purposes related to the fabric's ability to resist stains and repel water, respectively. These finishes do not influence the fabric's response to fire. Similarly, wrinkle-resistant finishes focus on helping fabric maintain its smooth appearance and do not contribute to fire resistance. Thus, the flame-retardant finish stands out as the essential treatment for enhancing a fabric's safety features against fire hazards.
