Physico-chemical studies finishing the song "Shtanteks S 6125" used in the manufacture of polyester fibers
A comprehensive study of the physico-chemical composition of the sizing-ing "Shtanteks S 6125", used in the manufacture of Napoli-United polyester fibers. IR spectroscopic study of diethylene glycol and triethylene confirms that the basis of the composition is hexaethyleneglycol. In addition, according to IR and UV spectroscopy of the dissection includes phosphoric acid esters, oleic acid, alkylamide and nonionic emulsifiers, likely from the class of ethers of alkylphenols. The tests of stability of composition applied as a 10% solution in water and fixed at 150 °C for 10 minutes on a polyethylene and a polyethylene terephthalate film, to the action of the dissolving solution. It is shown that the ability to washing compositions for the treatment of a single polyethylene terephthalate film, all solvents can be arranged in the following order: chloroform > hexane > carbon tetrachloride > 10% solution of powder "Crystal" in the water > water > ethyl alcohol.
