| titleOfInvention | Core material for writing implements |
| abstract | (57) [Summary] [PROBLEMS] For a writing instrument such as a conventional felt-tip pen, the tip portion of the leading core is deformed over time, and the line width is increased. Poor contact with the paper surface and blurring due to ink clogging cause poor durability. The present invention provides a core material which improves these drawbacks and enables a writing instrument which has a resilient front core, is hardly crushed, has a change in line width with time, and has little blurring of ink. SOLUTION: One component has a softening point or a melting point of 65 to 17; A terephthalic acid / isophthalic acid-alkylene glycol random copolymerized polyester at 0 ° C., the other component comprising a heat-fusible conjugate fiber composed of polyalkylene terephthalate having a melting point of 230 to 280 ° C. and a normal polyester fiber; The heat-fusible conjugate fiber, which is obtained by applying a hydrophilic processing agent having a polyetherester block copolymer as a main component to the surface of an adhesive conjugate fiber and / or a polyester fiber, and / or A core material for a writing implement, wherein a part of mutual contact points of polyester fibers is fused or bonded. |
