Description

BACKGROUND OF THE INVENTION

[0001] 1. Technical Field

[0002] The present invention relates to a method of flame-retardant treating a blend fabric, and more particularly to a method of flame-retardant treating a blend fabric which prevents the flame-retardant material of the flame-retardant treated fabric from being discharged to the outside when washed.

[0003] 2. Description of the Related Art

[0004] In order to prevent fire, the importance of flame-retardant function of fibers was rather early emphasized in the developed countries, and there are strong legal prescriptions for the use of flame-retardant fibers for fiber products used in public facilities, children's night clothes, airplanes, automobile seat covers, etc. Also in Korea, laws related to flame retardancy are being gradually enhanced, like the use of flame-retardant fibers in public facilities such as hotels. Alongside the increase in the flame-retardant fiber market, the demand of flame-retardant fibers is expected to become mu...

Embodiment Construction

[0025]Hereinafter, a method of flame-retardant treating a blend fabric according to a preferred embodiment of the present invention will be described in detail while referring to the accompanying drawings.

[0026]FIG. 1 is a schematic view showing a process of flame-retardant treating a blend fabric according to the present invention, and FIG. 2 is a flowchart showing the process of flame-retardant treating a blend fabric according to the present invention.

[0027]With reference to FIGS. 1 and 2, according to the preferred embodiment of the present invention, the method of flame-retardant treating a blend fabric comprising natural fibers and synthetic fibers to impart flame retardancy to the blend fabric includes flame-retardant treating natural fibers of the blend fabric using a flame retardant for natural fibers, and flame-retardant treating synthetic fibers of the blend fabric using a flame retardant for synthetic fibers. As such, flame-retardant treating of the chemical fibers is pe...
