“…At higher monomer concentrations, the homopolymerization increases preferentially resulting in hindered monomer diffusion into grafting sites and hence the grafting percent decreases. Also, 4-VP is wasted in the side chain reactions because of its high monomer-transfer value (CM= 7±2⋅10 -4 ), thereby decreasing percentage of grafting [38].Similar observations have also been reported by M. Nasef et al while grafting styrene onto fluorinated polymers [39].…”

With the aim of improving the basic characteristics of Track Etched Membranes (TEMs), functionalization by graft copolymerization has been attempted in the present work. Thin films (25 μm) of poly(vinyl fluoride) (PVF) (Tedlar) were irradiated by swift heavy ions (110 MeV Si 8+ ). The irradiated films were chemically etched to form latent tracks. Atomic Force Microscopy (AFM) was used to ascertain the formation of latent tracks. Irradiation effects were studied using UV-visible spectroscopic techniques. The tracks were functionalized by gamma radiation induced grafting with 4-vinyl pyridine (4-VP). In order to anticipate the best grafting conditions, percentage of grafting was studied as a function of various reaction conditions such as (i) total dose, (ii) monomer concentration and (iii) amount of water. Maximum percentage of grafting (13.66 %) was obtained at a total dose of 57.024 kGy using 2 ml of 4-VP in 10 ml of water. The grafted films were characterized by FTIR technique

“…Kandola et al [90] studied the influence of treatment of flame retardant to cotton on the mechanism of cotton pyrolysis. Photochemical grafting of 4-vinyl pyridine onto cotton fabric for imparting flame retarding properties has been reported [91]. Nakanishi et al [92,93] studied thermal degradation of cotton as well as flame retarded cotton and revealed that flame retardant cotton samples show extremely reduced amount and fewer numbers of gas products compared with untreated samples.…”

Cotton, jute and other natural fibre based textile fabrics are gaining popularity in domestic and international field due to its eco-friendliness and biodegradability characteristics and carbon sequestering advantages. This natural fibres based textile fabrics, if can be finished with natural or eco-friendly synthetic fire-retardant chemicals to satisfy the Required standard, it gets an extra dimension in the market and has a huge demand, if it is cost competitive. Cotton, jute, wool and silk based natural fibres have wide differences in their composition and properties and some inherent properties in common are higher flammability, higher moisture absorption and susceptibility to rotting/microbial attack, poor crease recovery etc., which have restricted its growth of their uses towards protective technical/functional textiles, though they have certain genuine advantages too as agrorenewability, bio degradability etc. To find more uses of such natural fibres as high valued technical textiles, as value added technical textiles, these natural fibre based textile fabrics have to undergo certain property modifications by specific improved chemical finishing as required especially for fire retardancy, water repellency, rot resistance etc. depending on its end use applications [1,2]. For the development of various types of functional finishing of jute and other natural fibres that too with eco-friendly formulations and processes, proper choice of eco safe chemicals along with suitable eco safe process parameters and optimization of process variables, water and energy requirement/consumption etc., are must and important for sustainability. So, in this review paper, different aspects of Fire-Retardant finishing of Jute and other natural fibre based textiles and their present perspectives have been discussed.

“…4-Vinyl pyridine has been used as fl ame retardant with benzophenone as photoinitiator for grafting onto cellulose fabrics using UV radiation technique. The thermogravimetric analysis (TGA) of the grafted fabrics showed lower decomposition temperatures with slight increase in char yield (Kaur et al ., 2007a ). Methacrylamide has also been grafted onto cotton with the use of low energy UV irradiation technique to introduce functionalities that can react with phosphorus-containing compounds to impart fl ame retardancy.…”

This chapter is a brief review of research and developments in the fi eld of fl ame retardant textiles. The review focuses mainly on the currently available fl ame retardant solutions for different kinds of textiles. It gives insights into the general mode of action of fl ame retardants, types of fl ame retardant fi bers, fl ame retardant additives for fi bers and surface treatments and standard test methods for fl ame retardant textiles. The existing commercial fl ame retardant treatments for textiles are over 50 years old and some of them have created environmental concerns. Over the past few decades there have been considerable developments in inherently fl ame retardant synthetic fi bers but effective and environmentally friendly fl ame retardant coatings or fi nishing solutions for textiles still elude us.
