There was a problem that should be.

Until now, the method of imparting flame retardancy to fabrics can be broadly divided into a pretreatment method and a post-treatment method. The pretreatment method is mainly used to obtain a flame retardant polymer material by copolymerizing a flame retardant monomer and a polymer fiber material.

Post-treatment methods include graft polymerization of flame retardant materials in yarn, woven, or knitted fabrics, and methods of penetrating and fixing flame retardant materials on fibers during dyeing or other processing.

Among the above methods, the pretreatment method has good durability in the flame retardant effect, but is used only for synthetic fibers, and thus there are limitations depending on the fiber material.

The post-treatment method is spray coating or coating the flame retardant material of the bromine-based, antimony-based flame retardant material, including ammonium diphosphate, sodium stannate, ferric oxide, manganese dioxide, urea monophosphate, calcium carbonate, aluminum hydroxide There is a method of imparting flame retardancy to the fibers by precipitating in the solution.

This post-treatment method is generally flame retardant in the tenter process during weaving, dyeing, dehydration and tenter process of weaving the fabric. The tenter process is to adjust the fabrics such as the fabric or the knitted fabric to a predetermined processing width. , A hot air fan composed of a plurality of chambers, refers to a process of drying the fabric while keeping the width of the fabric constant while sending the fabric at a constant speed.

When the fabric is flameproofed by the post-treatment method, the fabric must be heat treated to increase the temperature above a certain temperature, so that the flame retardant effect is maintained even after several washings. Fire retardant before sending to.

However, when the flame retardant treatment is performed in the tenter process, variously cut products possessed by the consumer have a problem in that the flame retardant treatment is difficult due to the characteristics of the tenter process that handles fabrics having a predetermined processing width.

In order to solve the problems of the prior art as described above, an object of the present invention is to be able to flame-resistant cut products, such as curtains, clothing, bed covers, etc. held by consumers, so that flame-retardant treatment can be used without discarding ready-made products. It is to provide a flame retardant treatment method.

In order to achieve the above object, the present invention provides a method for flame retardant fabric, washing step of removing foreign matter of the fabric; A drying step of drying the fabric washed in the washing step; Chemical treatment step of flame-resistant treatment of the fabric dried in the drying step to a solution of water and flame retardant by precipitation or spray method; And a dumbler step of putting the flame retardant fabric in the chemical treatment step into a dumbler and drying and heat-treating, wherein the dumbler step is put the flame retardant fabric in the chemical treatment step into a rotating dumbler at 120 ° C. A drying step of drying for at least 2 minutes; And a setting step of heat-treating the fabric dried at the drying step at 190 ° C. for 1 minute or more.

In addition, the washing step of the present invention to remove foreign matters of the fabric by washing means such as hot water and neutral detergent, the temperature of the hot water is preferably 40 ℃ or more.

In addition, the present invention is a solution of mixing the water and the flame retardant in the chemical treatment step is a mixed solution of 50% to 90% by weight of water, 10% to 50% by weight of the flame retardant is mixed at 50 ℃ or more for 30 minutes or more It is preferable.
