Process for preparing a liquid caustic composition for use in reactive dyeing which has target total and active alkalinities |
摘要 |
Liquid caustic compositions for use in reactive dyeing, having total and alkaline activities approximating the total and alkaline activities of a predetermined liquid caustic composition are prepared by providing a source of water; providing a container of concentrated sodium hydroxide solution; providing a container of liquid buffered alkali solution; providing a mixer communicating with the containers; providing at least one liquid caustic solution storage tank in communication with the mixer; providing flow meters communicating with the mixer to monitor the quantities of sodium hydroxide and buffered alkali flowing to the mixer; determining the total and active alkalinities of the target liquid caustic composition; determining the quantities of sodium hydroxide and buffered alkali solutions required to provide a liquid caustic solution having total and active alkalinities approximating the total and active alkalinities of the target solution; diluting the concentrated sodium hydroxide with the water to form dilute sodium hydroxide; feeding controlled quantities of the dilute sodium hydroxide and buffered alkali to the mixer; and mixing the sodium hydroxide and buffered alkali to form the desired liquid caustic solution.
