ROLE OF UREA IN PRINTED BASES ON THE BASE OF ETANDIOLPROPANDIOL-1.2-BLOCKSOPOLYMER
Polyester fibre is low in hydrophilic groups and is highly hydrophobic and low water absorption. Polyester fibre does not swell, making it difficult to dyeing fibre. A study of the possibility of reducing the concentration of urea in printing with disperse dyes fabrics of polyester fibre and replace printed compositions manutexes RS on synthetic thickener. An analysis of research on synthetic thickener based etandiolpropandiol-1.2 -blocksopolymer as intesificator dispersed dye fixing process. Found that as intesificator fixing process can be a particulate dye directly thickener - etandiolpropandiol-1,2-blocksopolymer, provided that the chemical structure of the polymer thickener, and its hydrophilic properties. Gidrodrofil character polymer thickener provides high sorption of moisture through the fabric applied with the film thickening, and its thermoplastic nature, which allows to ensure softening of the film during heat treatment, the printed fabric, thereby reducing the concentration of urea in the ink, or to exclude it from the composition at all.
