摘要:
Process for the purification of products of regenerated cellulose in which the regenerated cellulose product is passed through at least one washing segment where it is initially squeezed out with the aid of a squeezing element and then washed out with the washing water, passed in counter current, while simultaneously being deflected over deflection elements.
摘要:
A dispersion including anionic softeners and a process for producing compositions of anionic softeners is provided and obtainable by (a) reacting partial glycerides with maleic anhydride at a temperature above 53° C., wherein maleic anhydride is used in stoichiometric or below stoichiometric quantities to form a reaction product; and, (b) reacting the reaction product with an aqueous solution of sodium sulphite, wherein a quantity of water is selected to form a final product in the form of a 5 to 50 wt % aqueous solution. Powder compositions of anionic softeners may be obtained by drying the final product.
