What brush is of good quality and won't lose hair?

Painters in China often encounter such troubles: whenever a brush is used smoothly, it is often found that the brush begins to lose hair. It's a pity to throw away this brush-less brush, but it will affect painting if you don't throw it away. Most people will think that it is the quality of the brush, but it is not. The reason is that the hair root inserted in the pen tube does not dry quickly after washing. Over time, bacteria grow and the hair of the pen root decays and falls off. Generally speaking, thinner pens are not easy to shed hair because they dry quickly, and thicker brushes are easier to shed hair, especially wool brushes. When the calligrapher washes the brush, the residual ink in the hair root is not easy to lose hair because there is glue to catch. After each painting, the painter needs to clean the brush thoroughly. If you stay in water for a long time, you will lose your hair.

The way to prevent the brush from falling off is to fill the hair roots in the pen tube with rosin, so that water can't stay inside.

First, prepare rosin, alcohol, small plastic bottles, injection needle tubes or unused ballpoint pen tubes and thin threads. Rosin can be purchased from musical instrument stores, and both medical alcohol and industrial alcohol can be used.

The brush that needs to be repaired must be completely dry. First, put rosin fragments and alcohol in a bottle according to the ratio of about 1: 1, and stir until the rosin is completely dissolved. Then one hand holds a brush with separate bristles, and the other hand inserts the ballpoint pen tube into the rosin solution to let the solution enter the pen tube. Then press the upper end of the ballpoint pen tube with your thumb to prevent air from entering and the solution from flowing out. Then insert the ballpoint pen tube into the root of the brush and lift your thumb to let the rosin solution penetrate. Immediately pinch the bristles at the root to make the solution completely uniform and full, and gently close the nib with a thin thread, arrange and finalize the design, with the nib facing up. After a few hours, the alcohol completely evaporated, leaving only rosin to fill the pen tube. At this time, loosen the thin thread, rub the pen tip on the little finger side with your palm, crush the rosin outside the pen tube, and bounce off the rosin powder.

In order to prolong the service life of the brush, the used brush should be cleaned in time, and the water in the nib should be squeezed out with waste rice paper or paper towels, and then the nib should be loosened to facilitate the evaporation of water. After washing the pen, it is not advisable to straighten the bristles or insert the nib into the pen cap, because it is not easy to evaporate and stay at the root of the pen, causing the bristles to rot and fall off.
