Description

[Detailed description of the invention] This invention relates to a Hewei textile brush made of bundled fibers.The purpose is to improve ink circulation, and to have a strong stiff tip with a soft tip similar to a natural fiber brush. It's all there so you can get the full flavor of writing.

In conventional Hewei fiber brushes, the cross section of the synthetic fibers was circular and the tips were simply tapered, so when bundled, the ink flow path between each fiber became extremely narrow, resulting in insufficient ink flow. Moreover, the softness of the tip is not as hard as that of a brush made of natural fibers, resulting in a poor writing taste.

The present invention aims to eliminate such drawbacks.

1 to 3 show the first embodiment of the present invention, which includes polyamide-based, polyacetal-based, polyester-based,
Synthetic resin such as acrylic resin is extruded by, for example, a monofilament self-fusion method to form a threat fiber having a shape in which two vertically thick parts 1a with a circular cross section are connected by a vertically thin part 1b, and further, for example, a solution is formed. When the diameter of the tip of the synthetic fiber is reduced by treatment with
a/, 1 a/ is expressed.

When such synthetic fibers 1 are bundled, as shown in FIG. 3, an ink flow path 2 is formed between each synthetic fiber 1 which is much larger than the ink flow path of a conventional fiber brush.

FIG. 4 shows a second embodiment of the present invention, in which three thick longitudinal sections 10a made of the same material and shape as in the first embodiment are arranged in a straight line, and the adjacent section is formed by a thin longitudinal section 10b. It is connected as one piece.

FIG. 5 shows a third embodiment of the present invention, in which four vertically thick portions 20a of the same material and shape as in the first embodiment are provided at the center and around the outer periphery.
The contact portions with the center are integrally connected by a vertically long thin portion 20b.

FIG. 6 shows a fourth embodiment of the present invention, in which four vertically thick sections 30a of the same material and shape as in the first embodiment are provided at the center and around the outer periphery.
The center and four outer circumferences are integrally connected by a vertically long thin section 30b.

FIG. 7 shows a fifth embodiment of the present invention, in which four longitudinal thick sections 40a made of the same material as the first embodiment are arranged in an annular shape, and both ends thereof are integrally connected by a longitudinal thin section 40b. However, there is an ink flow hole 40c inside.

FIG. 8 shows a sixth embodiment of the present invention, in which four longitudinally thickened portions 50a of the same material and shape as in the first embodiment are arranged at equal intervals, and each of the longitudinally thickened portions 50a is A vertically elongated thin section 50b between the outer peripheries
The ink flow passages 50c are integrally connected to each other and an ink flow passage 50c is formed inside.

FIG. 9 shows a seventh embodiment of the present invention, in which six vertically thick parts 60a made of the same material as in the first embodiment and each having a regular triangular cross section are arranged in a regular hexagonal shape, and the adjacent outer peripheral part is vertically long. Connected by thin wall portion 60b,
An ink circulation groove 60c is formed inside the vertically long thick portion 60a and the adjacent portions communicate with each other at the top.

The tip portions of the second to seventh embodiments described above are similar to those of the first embodiment, for example, by processing with a solution, the longitudinally thickened portions 10.20a, 3.
0a, 40a, 50a, 60a are made thinner at the tips, and longitudinally thinner parts 10b, 20b, 30b, 40b, 50b are formed.
, 60b is separated and split ends are removed.

When the synthetic fibers 10, 20, and 30 of the second to fourth embodiments are bundled, an ink flow path that is sufficiently larger than the ink flow path of a conventional fiber brush is formed between each fiber, similar to the first example. and synthetic fibers 40, 50, 60 of the fifth to seventh examples
When made into a bundle, there are ink flow passages inside each synthetic fiber itself as well as between each synthetic fiber, so that an ink flow passage as a whole is formed that is sufficiently larger than the ink flow passage of a conventional fiber brush.

. According to the present invention, a plurality of vertically thick parts are connected by a vertically long thick part, the tips are tapered, and the vertically thick parts are dissolved and separated with a solvent to form split ends, and the synthetic fibers are bundled together. Since it consists of a fiber brush,
Compared to conventional Hewei fiber brushes, it can form a sufficiently wide ink flow path, and the tip can be easily made into split ends, resulting in a strong, soft tip and a writing feel similar to that of a natural fiber brush. be able to.

In addition to various dye inks, pigment inks such as black ink can also be used as inks, but in this invention, inks with high viscosity can also be used, and can be used as various painting brushes and makeup brushes. can do.

In addition, in the present invention, the brushes shown in each of the above embodiments may be arbitrarily mixed and made into a bundle, or the brushes may be made by mixing natural hairs or conventional synthetic fibers with a circular cross section. It goes without saying that it can also include things that are made up of bodies and things that are made up of brushes.
