Abstract
Among the various advanced materials, flame-retardant cellulosic textiles are important as they directly relate to human health and hazards. The use of environmentally friendly flame-retardant coatings is currently one of the major concerns in the textile coating industry. In this work, acrylic acid was grafted onto the surface of cotton using plasma technology to enhance the attachment of acrylate phosphate monomer. Surface analyses, such as scanning electron microscopy (SEM), energy dispersive x-ray (EDX) and attenuated total reflectance Fourier-transform infrared (ATR-FTIR), were carried out to characterize the coating. Textile properties such as wettability and mechanical properties of untreated and treated cotton samples were investigated. A laundering test was also performed to predict the durability of the finishing. The outcomes revealed that acrylic acid-grafted samples treated with acrylate phosphate monomer have good flame-retardant properties.

Cotton is a natural fiber in which cellulose represents the major component of its chemical structure.Nowadays, cotton fabrics are widely used in our daily lives due to their remarkable combination of properties: soft to the touch, good moisture vapor transmission and good moisture absorbency [1]

Summary
Cotton is a natural fiber in which cellulose represents the major component of its chemical structure.Nowadays, cotton fabrics are widely used in our daily lives due to their remarkable combination of properties: soft to the touch, good moisture vapor transmission and good moisture absorbency [1]. The flame-retardant finishing of cotton fabrics is important as it is strongly related to the protection of human beings and textile substrates from fire hazards In this context, the assessment of the flammability of cotton substrates has been approached by applying suitable flame-retardant finishes that are able to suppress or delay the appearance of a flame or reduce the flame-spread rate [3]. The assessment of the flammability of cotton substrates has been approached by applying suitable flame-retardant finishes that are able to suppress or delay the appearance of a flame or reduce the flame-spread rate [3] These finishes are applied to textiles by using a variety of agents, including borax and boric acid mixture, nitrogen- and phosphorus-based chemicals, antimony and halogen based chemicals [4]
