Functional properties such as; water resistance, flame retardancy, antibacterial efficiency etc. arerequired from textile products. One of the most commonly demanded products among functional textileproducts is the flame-retardant textiles. In this study, it is aimed to produce polypropylene filament yarn withpermanent flame retardancy functionality by adding boron compound, which is Anhydrous disodiumtetraborate powder (particle size < 38 micron), to the fiber structure during melt spinning process. In thisstudy two different yarn samples are produced with anhydrous disodium tetraborate content by mass ratios of2% and 5%. A control polypropylene filament yarn sample is also produced with no additive. By this way,three samples are produced by a conventional BCF polypropylene melt spinning machine with the sameproduction parameters. Then, three knitted fabric samples were produced flat knitting machine. LimitingOxygen Index (LOI) and vertical flammability tests were applied to the samples. According to results animportant level of increase for LOI value is obtained with the sample which has 2% boron compound additive.Nevertheless, there is not a consistent effect of increasing boron content in yarn structure for LOI value. Thereason of this situation may be resulted due to the uneven distribution of the boron compound in the yarnstructure because of the particle size.
