In order to establish the standard manufacturing condition of PET flame retardant sheets, physicochetnical properties of the samples made by the conventional flame-retardant finishing were systematically investigated, including compatibility among flame retardant agent and finishing auxiliaries, surface property, and wicking property. From this results, the addition of washing and renapping process after the shearing process was required for the more effective in producing PET flame-retardant sheet by the standard finishing. The effect of the modification of the regular flame retardant finishing process was studied by FTIR, TGA, and flame retardancy test.

The objective of this study is to apply water repellent and flame retardant finishes simultaneously to the fabric used for automobile. Both two step and one step methods were tried to apply the finishing agent to the fabric. In the two step method, water repellent agent was treated first, and flame retardant agent was applied next. The reverse finishing process was also attempted. In the one step method, flame retardant agent and water repellent agent treated to the fabric in one bath. The results of two step method revealed that the finishing effect was better when the water repellent agent was treated first than when flame retardant agent was treated first. In one step method, fluoro water repellent agent was superior to silicon water repellent agent.

Flame-retardant finished silk fabrics could release carcinogenic formaldehyde resulting from the conventional finishing agents. New water-soluble cyclophosphazene derivative can be used as a formaldehyde-free flame retardant for the silk protein. Dichloro tetrakis{N-[3-dimethylamino)propyl]methacrylamido}cyclophosphazene(DCTDCP) can be cured by heat or UV irradiation as a durable flame retardant for the silk fabrics. Treatment conditions were optimized including curing temperature and time, finishing formulations, and UV energy. At the 30% DCTDCP application, peak HRR and THR decreased by 42.6% and 49.6% respectively compared to the pristine silk fabrics. Also char residue increased up to 48% from 11% indicating solid-phase retarding mechanism. The flame-retardant silk fabrics showed a LOI of 31.1 and the washed sample maintained a LOI of 26.8 even after ten laundering cycles.

The need for the effective flame retardant finishing for synthetic fiber Is required. This paper is focussed on the analysis of physical properties of nylon 6 fabric treated with tris(2-chloroethyl) phosphate(TCEP) in comparision with the untreated fabric. In order to evaluate the flame retardance effect, limiting oxygen index and burn rate were determined. Above 20% add-on of TCEP on nylon 6 fabric, reasonable flame retardancy was observed. Thermal stability of the treated nylon 6 fabric was evaluated by TGA. It seems that TCEP acts via a condensed phase mechanism. Tenacity and moisture regain of the treated fabrics were not changed and washfastness of those was excellent.

The ultimate purpose of this study is to improve the irrational system related to flame retardant coating performance test of field flame retardant coating articles and to secure the reliability of flame retardant coating through rational flame retardant coating test. To achieve this, the analysis was conducted on the interior finishing materials used in the interior fields and the trends of recent field flame retardant coating, based on the results of flame retardant coating performance test of field flame retardant coating articles which the first-line fire stations have recently conducted. And I attempted to present the methods of field flame retardant coating performance test suitable to current realities and the ways of improvement for securing reliability by analyzing the problems with the methods and procedures of field flame retardant coating articles and the registration system of flame retardant coating business.

The pegging board planning for jacquard weaves was carried out to express a big enough design in 60 inch width. 20 Kinds of fabrics were fabricated by a jacquard loom with a warp density of 168 yarns/inch, a weft density of 100T, and a weight of 180-220g/$m^2$ or 250-300g/$m^2$. The result of sanitary test about Escherichia coli, Staphilococcus aureus, Klebsiella pneumoniae and Salmonella typhimurium showed a sterilizing power of over 90% after cultivating for 30, 60, 120 minutes. And also its property was sustained after laundrying 20 times. The flame retardant properties showed a good result and complied with the flame retardant criteria of KOFEI 1001. Abrasion, laundry and light fastnesses of flame retardant fabrics showed 4-5 grades. The fabrics manufactured from 30's fiber appeared a little fluff and pill on the fabric. Therefore, they need a shearing process after finishing all processes to decrease the fluff or pill on the fabric. The flame retardant fabric manufactured from 30's and 40's fiber showed increased strength and elongation after soaping and dyeing finishing because the fabrics were shrunk.

Effect of disperse dyeing on flame retardant finishing of PET fabrics via UV curing using three UV curable phosphorous-containing methacrylates and ammonium polyphosphate(APP) was investigated. The dye fixation and flame retardancy of PET fabrics did not change significantly with excellent durability to five laundering cycles irrespective of the dyeing and finishing sequence. However, the flame retardancy of Pekoflam-treated fabrics was lower than that of the UV treated and decreased substantially when heat treatment was carried out before the dyeing. The dyeability of the flame-retardant PET fabrics was not affected in the case of UV curing of the methacrylates alone. However, UV finishing after the dyeing caused significant decrease in K/S and ${\Delta}E$ due to changed refraction and inherent color of surface coating of the UV curable monomers and APP. Whereas the heat treatment with Pekoflam decreased both color fastness to laundering and sublimation, surprisingly the UV finish of PET fabrics before and after the dyeing increased the color fastness probably resulting from the presence of photopolymerized surface layer on the fabrics.

In this study, a non-halogen type organic-inorganic hybrid flame retardant sol, which can impart flame resistance to synthesize silicate of inorganic material and silane coupling agent of organic material by a sol-gel method, were newly manufactured. The addition of flame retardant will prevent loss of life in a fire because smoke from the flammability of interior finishing materials used as the construction materials poses a major danger. The smoke density measurement standard based on flame retardant performance standards, experiments were conducted according to the test equipment and procedures of ASTM E 662. The non-flaming mode experiment and the flaming mode experiment were conducted to confirm the performance of the manufactured flame retardant sol. As a result, the manufactured flame retardant sol improved the physical properties and heat resistance of existing flame retardants, and decreased the smoke production of the fire. Therefore, it may be possible to reduce the damage caused by smoke and expand the applications to various interior finishing materials.

In this study, the effect on flame retardancy and various physical properties when TiO₂ was added with a citric acid/phosphate complex acid catalyst together with Pyrovatex CP new (N-methylol dimethylphosphonopropionamide), a phosphorus-based flame retardant, was studied on cotton fibers. SEM-EDS analysis was performed to confirm the surface characteristics and surface element analysis of the flame-retardant treated cotton fibers, and a vertical carbonization test was performed to confirm the char formation capability and flame retardancy according to the phosphoric acid ratio. By comparing the LOI index before and after washing 10 times, the washing durability of the flame retardant solution containing the phosphoric acid catalyst and TiO₂ was tested by LOI index after ten washing cycles. In addition, the influence of the flame-retardant processing on the physical properties were compared including thermogravimetric analysis (TGA), tear strength and whiteness.
