The brush hair of a common brush can be divided into nine categories according to different text styles. Text styles include nine types: Large Seal, Small Seal, Clerical Script, Regular Script, Running-Standard Script, Running Script, Semi-Cursive Script, Cursive Style and Wild Cursive Style. Depending on the size of the brush hair, there are eighteen sizes ranging from 4 mm to 21 mm. Each size of brush hair has three lengths, which can be divided into long, medium and short lengths. The belly part of brush hair can be divided into three types of hardness according to elasticity. In terms of size and rigidity of writing brushes, there are a total of 162 types of writing brushes. For example, when selecting a brush based on the needs of the text style, when using the Seal and Clerical Script styles as the handwriting style, in order to better control the performance of the handwriting, the length of the brush hair should be longer, and the length of the brush hair should be longer. The belly area should be softer, and the elastic pressure of the brush hair should be less. When using the Cursive Script style as the writing style, in order to move the writing brush freely and vigorously in the process of pressing and releasing quickly, the length of the brush hair should be longer, the belly part of the brush hair should be firmer, and the elastic pressure of the brush hair should be larger Therefore, when choosing brush hair, according to the desired writing style, the font size must first be determined, then the size of the brush hair must be determined, and finally, the rigidity of the upper part of the brush hair must be determined, which is an appropriate writing brush. principle for choosing

Table 2: Writing brushes with medium brush hair length

Boat part diameter of 16 mm pressure value hardness
medium hair 280 g stiffness 215 g middle 165 g Soft

Table 3: Writing brushes with short brush hair lengths

Boat part diameter of 16 mm pressure value hardness
short hair 324 g stiffness 249 g middle 192 g Soft

According to the above test results, the writing brushes 40 having different lengths of the brush hairs 42 have different pressure values, and the stiffness of each brush hairs 42 is further classified according to the pressure values of the brush hairs 42 . do. Accordingly, the brush hair 42 of the same length can be divided into a hard level, a medium level and a soft level.
