Embodiment 1

[0055] A preparation method for a marker tip, the steps are as follows:

[0056] (1) the nib of 1.3dtex is washed and dried with polyamide fiber to monofilament fineness;

[0057] Wherein, the preparation process of the polyamide fiber for the nib is as follows:

[0058] According to the FDY process, the high viscosity PA6 melt (intrinsic viscosity is 2.59dL / g) and the low viscosity PA6 melt (intrinsic viscosity is 2.26dL / g) with a mass ratio of 45:55 are distributed, and then from the same spinneret After the spinneret holes are extruded to obtain FDY filaments, relaxation heat treatment is carried out to obtain polyamide fibers for pen heads;

[0059] The spinneret holes on the spinneret are shaped spinneret hole, The shape is composed of a horizontal line and the oblique line I and II connected with it; the angle between the oblique line I and the horizontal line is 43°, and the angle between the oblique line II and the horizontal line is 65°; oblique line I, oblique l...

Abstract

The invention relates to a preparation method of a pen point of a mark pen. The method comprises the following steps of: (1) washing and drying the pen point by using polyamide fibers; (2) dipping byadopting a two-component polyurethane adhesive; (3) preheating and curing and foaming the soaked fiber bundles; (4) cutting and grinding fully foamed fiber bars; and (5) cleaning and drying to obtainthe pen point of the mark pen. The preparation process of the polyamide fibers for the pen point comprises the following steps: distributing high/low viscosity PA6 melts according to the FDY process,extruding the high/low viscosity PA6 melts from spinneret holes on the same spinneret plate to obtain FDY filaments, and performing relaxation heat treatment to obtain the polyamide fibers for the penpoint. The cross section of each spinneret hole is in a shape seen the specification, and each spinneret hole comprises a transverse line and further comprises an oblique line I and an oblique line II which are connected with the transverse line; and distributing refers to controlling the flow of the high viscosity PA6 melt through the transverse line while controlling the flow of the low viscosity PA6 melt through the oblique line I and the oblique line II. The preparation method is simple, and the prepared pen point of the mark pen has good writing experience.

Description

technical field [0001] The invention belongs to the field of fiber technology and relates to a method for preparing a marker tip. Background technique [0002] In recent years, synthetic fibers have been widely used in the pen industry. The internationally popular marker pen is a new type of writing tool that uses nylon elastic yarn as the tip and polyester fiber as the water storage core. Mark pens are widely used in education, office, painting and industrial design because of their smooth writing, uniform and full color, various types of ink colors, no dust when writing, the width of handwriting can be changed at any time when writing, and can be wiped after writing. and other fields. [0003] The structure of the marker pen is mainly composed of four parts, including the nib, the water storage core, the ink and the support part of the plastic shell of the pen. Only when they are properly matched can the marker pen function. The tip of a marker pen is generally made of ...
