Sažetak
Nowadays, resistance to fire is one of the most frequently requested functional properties for textile materials. The flammability of textiles is a complex property in terms of both, the process mechanisms to which the material is exposed such as: chemistry, physics and the environment, so as the potential dangers for people and their societies from any loss of material values regarding health or even loss of life. Cellulose materials (cotton, linen, jute, hemp, cellulose regenerators) are easily combustible, i.e. they burn quickly with quickly-spreading flames around the complete area. The engulfing smoke from these materials can cause burns, respiratory damage, or even death. In regard to these facts, to date a whole range of different resources for processing against the burning of cellulosic materials has been developed, which are fleeting, semi-continuous, and stable processes for washing and dry-cleaning. On the other hand, synthetic fibres (acrylic, polyester, polyamide) resist ignition, but at high temperatures can cause serious burns. The behavioural characteristics of cellulose and synthetic materials during fires have prompted the design of modacrylic cotton-blended yarns in different proportions, in order to create reduced flammability products. The paper used thermo-gravimetric analysis (TGA) to characterize the obtained yarn with respect to reduced flammability properties. Bringing heat to the sample leads to different physiochemical changes that can help in the identification and characterization of the sample. This method can produce information on the thermal decompositions of the studied systems (the starting temperature of thermal decomposition and the mass loss during it) in an inert or reactive atmosphere, and the moisture content in the sample, etc. The proportion of inorganic components can be determined from the burn-free residue. This paper also examines the eligibility of zeta potential measured on the SurPASS instrument, Anton Paar, Graz, Austria, in order to characterize those surface-functional yarns designed to achieve the properties of reduced flammability. Electrokinetic potential, known as the zeta potential is a significant parameter within electrokinetic phenomena. It originates from the accumulation of electrical charge during the solid/liquid phase.
