Abstract:
A wool or the like fiber scour including at least one of the following, (a) scouring process wherein the fiber is subjected to an acid extraction process to remove absorbed iron, and by to greatly improve the brightness (Y tristimulus value) of the wool; (b) a scouring process wherein a bleaching process is carried out part way through the wet process following by dying, rewriting and chemical reduction, therefore stabilising the bleached color to prevent subsequent reversion in the dyebath; or (c) a scouring process wherein scoured clean fiber is dried and dusted, and then reimmersed in liquors containing detergents and dispersants, thereby effectively removing extra amounts of residual dirt. The scour produces an improved quality of fibres.
Abstract:
The invention relates to a system and method for processing of fibres and particulates such as wool, wherein material is placed within a receptacle configured to allow the ingress and egress of treatment fluid, conveyed to a treatment fluid application area, treated with a treatment fluid, and conveyed from the treatment fluid application area.
Abstract:
A method and apparatus for compositing putrescible waste material, the apparatus including a stationary elongated compositing chamber which is mounted to be generally horizontal in orientation or slightly inclined from an inlet end to an outlet end and includes at least one rotatable shaft therein with paddles or tines that extend therefrom in a generally helical pattern. Rotation of the shaft causes the composting material to move along the chamber. Air is injected into the compositing chamber and accumulates in a headspace above the compositing material where it is measured for flow rate, gas content and temperature and eventually removed from near an inlet end of the chamber.
