Abstract
Abstract An apparatus for measuring and computing the amount of a soluble material, such as a finish, plasticizer, lubricants and the like, contained on a carrier material, such as plastics, metals, natural and synthetic fibers in the form of tow, yarns or staple fibers. A weighing means measures the weight of a fiber sample and produces a signal representative of the measured weight. A data processor stores the weight signal while the content of the soluble material in the sample is being measured. A sample container is supported by a conveyor means which moves the sample from a loading zone to a testing zone and thereafter to a disposal and washing station. Solvent dispensing means automatically dispense a predetermined volume of a solvent for the soluble material from a source into the sample container. Agitation means agitate the solvent to quickly disperse the soluble material on the sample into solution. A predetermined volume of the resulting solute is removed from the container automatically by solute measuring means and the measured amount of solute is fed to an analyzer which determines the proportion of soluble material in the solute. The analyzer produces a signal proportional to the soluble material weight on the fiber sample. The soluble material weight signal is supplied to a data processor which then computes the percent soluble material on the starting fiber sample.
