Abstract:Together with the industrialization, the safety of human turned into an important subject. The developing field of textile industry includes new developments in fibers, fabrics and protective clothes. Unflammable textile industry produces environmentalist, non-toxic and comfort implementing unflammable systems. The life and goods losses in fires that are followed by the accidents in daily life, automotive, space and aeronautic fields cause the arise of new criterion and sanctions. The laws and restrictions have excited the scientific and technological researches in order to make natural and synthetic polymeric materials ranging from daily used textiles to plastic materials used in modern transport vehicles resistant to flame. In this study, acrylic and wool mixture materials that are widely used in textile industry were used. Flame resistant chemical was applied to acrylic and wool, and plasma polymerisation was applied to viscon fabric. For doing this, organophosphorus was applied to acrylic and wool, boric acid and organophosphorus was applied to viscon fabric. In plasma polymerization trimetylborate was used as monomer and argon and oxygen gases were used for surface activation. The production technique was blend method and the chemical application was pulling and pad dry. During the characterization step of materials, thermogravimetric analiz (TGA) were used for the determination of thermal properties, scanning electron microscopy (SEM) for the characterization of plated surfaces, limit oxygen index (LOI) for the determination of burning properties, fastness test for the observation of the fastness properties of the product after the chemical application and contact angle measurement for the determination against water. LOI test results show that boric acid with pad dry method have a very good flame resistant effect on viscon fabric and organophosphorus with pulling method have a very good flame resistant effect on acrylic wool composition. The application of both 20% organophosphorus containing chemical and pulling method to the acrylic wool composition increased the LOI value of the samples from 18,7 to 19,75. The application of both boric acid containing chemical with emdirme kurutma method to the acrylic wool composition increased the LOI value of the samples from 18,8 to over than 55. Using both boric acid containing chemical and pad dry method has increased the LOI value. The TGA thermograms have supported this result. At the end of the fastness test, the samples were proved not to cause a problem during the usage. In the contact angle test, it was assumed that plasma activation with oxygen gives the most hydrophilic structure. SEM micrographs used for the observation of the plated surfaces showed that the plate activated by the oxygen plasma is successful.
