Development of hydro-centrifugal method of forming womens headwear

Abstract

The influence of phytic and citric acids additives on the structure of polymer films formed from the Neoprint PNA/S acrylic polymer was investigated in order to develop finishing compositions for fire protection of textile materials. Standardized methods were used to study the structure formation of acrylic polymer films filled and unfilled with phytic and citric acids in various ratios. The degree of interaction between the components of the polymer system has been estimated and it was found that increasing the concentration of phytic acid enhances the interaction between the filler and the matrix. It was shown, that with an increase in the concentration of phytic and citric acids in the composition of the polymer film, the degree of crosslinking and the fraction of active chains of the acrylic polymer increase. The formation of a significant carbonized residue of the polymer film containing phytic and citric acids after exposure to an open flame is shown. The absence of splashing of the burning polymer melt, in contrast to the film formed from pure polymer, was noted, which excludes the potentially destructive effect in the form of melt dripping, which causes additional hot spots. The results obtained are of practical importance for the development of composite fire retardant finishing compositions for textile materials.
