Flame retardant finish on furniture textiles

124 s. :il., tab., grafy +CD ROMFlame retardants save many lives and property because they prevent accidental fires. On the other hand, there are concerns related to chemical release into the environment and potential health effects. Since halogenated flame retardants have been in the focus of public scrutiny, flame retardants based on other chemistries like phosphorus and nitrogen have been developed and need to prove their environmental benefits. This study is concentrating on discussion of specific problems of flammability and flame retardation of the polymer in terms of its molecular structure and its application. The methodology of testing for polymer flammability, the significance of test results, and their correlation with fire hazard form a complex subject which is beyond the scope of this diploma thesis. Flame retardancy standards for public safety are generally controlled or influenced by government departments. Flame retardancy is required in many coated products, and a polymer coating can hold a larger amount of FR chemical than a simple finish on a fabric. The use of coatings is widely used and for many purposes. Most items that we own are coated. Coating is applied to render a certain property on a fabric and to protect materials from corrosion and other detrimental effects of the ambient atmosphere. Surface properties such as gloss, color, slipperiness, they change and make the surface beautiful. In many cases coatings are applied to improve surface properties of the substrate, such as appearance, adhesion, wet ability, wear resistance, and scratch resistance. Wide range of applications techniques, coating types and purposes makes coating an extremely diverse field. Coatings may be applied as liquid, gases or solids. Coatings can be measured and tested for proper opacity and film thickness. There are processes that had to be followed when applying coating on a fabric. Achieving high level properties in coating technical textiles requires implicit knowledge of the fabric, the polymers with their strengths and weaknesses, and the technology. The right selection and combination of polymers depend on end use and technical properties. . Literature is covering various aspects of polymer flammability, flame-retardant compounds for polymers, and of possible improvements in the fire safety
