method for manufacturing flame retardant cotton fabric with excellent washing durability

摘要

The method of manufacturing a flame-retardant cotton fabric having excellent washing durability according to the present invention is a mercerization process in which a single yarn of cotton fibers with a pre-twist according to the spinning process is treated with a sodium hydroxide solution of 15% to 20% concentration to remove the skin layer of the cotton fibers ; Dye treatment and washing process for the mercerized single yarn; Flame-retardant treatment process for the dyed single yarn; A ply-twisted yarn manufacturing process in which the flame-retardant-treated single yarn is followed by a target number of twists, the driven single yarns are twisted, and then twisted to produce a ply-twisted yarn; A weaving process in which the ply-twisted yarn is not washed with water after weaving, so as not to use a refined oil, and to prepare a fabric by performing a canonical setting; A first curing process for the fabric; A decatizing process in which the first cured fabric is repeatedly applied in a vacuum state and an increased pressure state using high temperature/high pressure steam; A second curing process for the decatized fabric; And a first finish in which fibrils of cotton fibers are combined by heat and pressure on one side of the second cured fabric by passing one side of the second cured fabric in close contact/pressurization through a high-temperature cylinder. Process can be included.
