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.
Claims8
A method of making a fibrous body for use in an ink reservoir, comprising the steps of:
- supplying a plurality of fibers of false twist stretch yarn;
- gathering said fibers in an unprocessed bundle;
- supplying a chamber for passage of said bundle of fibers therethrough;
- supplying a means for heating said bundle of fibers;
- said means for heating supplying heat to said chamber during passage therethrough of said bundle of fibers;
- heating said bundle of fibers by said means for heating;
- permitting tangling of said bundle of fibers in said chamber due to application of heat thereto by said means for heating;
- drawing said tangled bundle of fibers from said chamber;
- cooling said tangled bundle of fibers;
- said tangled gathered bundle of fibers upon cooling forming a relatively strong fibrous body.
