Abstract
An apparatus for producing an ink reservoir material, the reservoir material itself, and a method for making the ink reservoir material, include use of false twist stretch yarn. The yarn is used together with a steam die heater to cause crimping of a yarn bundle, so as to tangle, forming a relatively strong, relatively stable fibrous body usable as an ink reservoir material having good ink-holding properties and to prevent leakers. The ink reservoir can be used with a film overwrap or extruded coating layer. An ink pen uses the ink reservoir material.
