Description

Writing brush head, preparation method and application thereof

Technical Field

The invention relates to the field of calligraphy tools, in particular to a writing brush head, a preparation method and application thereof.

Background

Calligraphy is a cultural treasure of Chinese nationality, is a precious wealth of human civilization, and with rapid development of information technology and popularization of computers and mobile phones, communication modes and learning modes of people are greatly changed, so that the writing capability of Chinese characters of primary and secondary school students is weakened. In order to inherit and carry forward excellent Chinese culture and improve the quality of the Chinese, a document No. two [ 2011 ] 4, namely the opinion about developing calligraphy education in middle and primary schools, is proposed by the 2011 education department, and after a document No. two [2013]1, namely the guidance outline of calligraphy education in middle and primary schools, is published in 2013, calligraphy is formally taken as a necessary repair course to be brought into a teaching system of the middle and primary schools; and formally confirming that the special character of the calligraphy of the primary and middle school students is added by 10 points in the file of teaching art No. 2015 5.

The calligraphy learning method needs to be performed through copying, wherein the copying is the only correct way for learning the calligraphy and runs through the whole calligraphy learning process. How to correctly evaluate the copying effect is very critical to learning good calligraphy.

Strokes are the basic elements that make up a Chinese character. To write a word, strokes are written first. The basic strokes of Chinese characters are more than forty, which can be divided into points (oblique point, vertical point, left-falling point, lifting point), lines (long horizontal, short horizontal, left tip horizontal, hanging needle vertical, short vertical, long oblique left-falling, short horizontal left-falling, vertical bent left-falling, vertical left-falling, oblique right-falling, horizontal right-falling, reverse right-falling, lifting), bends (transverse bend, vertical bend, left-falling bend), hooks (transverse hook, vertical hook, oblique hook, horizontal hook, vertical left-bent hook), composite strokes, etc.

The pen transportation is the root of calligraphy and is the most important of calligraphy. The completion of a stroke requires three processes of starting, running and closing, and the action process is carried out when the stroke is up to the horizontal, vertical, left falling and right falling and when the stroke is down to a point.

From a calligraphy perspective, the pen is expensive to use. The tip of the writing brush tip is provided with a transparent or green part, namely the writing tip. Using … … full stick tip sharp finger for use, or using the tip positively, laterally, reversely, clockwise, heavily, lightly, practically, and virtually. The running track according to the stroke front can be divided into 11 types: middle cutting edge, inverse cutting edge, reverse cutting edge, turning cutting edge, folding cutting edge, hiding cutting edge, exposing cutting edge, moving cutting edge, side cutting edge, deflecting cutting edge, spreading hair. The stroke is used, that is, the position of the stroke in the stroke line operation is to be held (as shown in fig. 1).

For people with calligraphy experience, the position of the pen point can be judged by the experience, and then the pen point can be adjusted in practice, so that an ideal copying or creating effect is achieved. And for the beginner, the copy image on the calligraphy copy paste is solid Chinese character, the ink color distribution of the characters copied by the existing writing brush is almost even, the beginner can not judge the inherent running track of the pen point in the walking process because of insufficient experience, the copying effect can not be accurately judged, an experienced person is required to point and correct, the exercise time and the exercise efficiency are greatly limited, and the writing brush calligraphy exercise is very dull. How to provide convenience for a copier to judge the copying effect and greatly improve the interest of calligraphy practice of writing brushes becomes a technical problem to be solved urgently in the industry.

Patent document CN101236704A (publication date 2008, 8/6) discloses a writing brush calligraphy copying paste and a writing brush calligraphy copying method, in which the outline of the copying image is set to a double-hook outline, which improves the enjoyment of copying and also helps to determine the copying effect to some extent. However, the copying method cannot be used for judging the internal running track of the pen point, so that the method is not helpful for accurately and professionally judging, further automatically adjusting and improving the copying effect. Patent document CN102991262A (published 2013, 3, 27) can achieve calligraphy effects of different thick and thin tones by using thick and thin inks in combination, but mainly aims to increase appreciation value and artistic appeal of works, and cannot accurately grasp the stroke trajectory. Patent document CN2616387Y (5, 19, 2004) can realize a color writing effect by dipping two or more pigments at the same time, and also cannot accurately display the stroke trajectory.

The writing brush consists of a brush head and a brush holder, and the emphasis is on the brush head. The hair materials used by the writing brush are mainly made of animal hair in the heading of the calendar, the selection of the hair materials is very wide nowadays, the animal hair can be almost used for making pens, and more common animal hair can be used for making pencils, such as chinchilla wolves, goats, horses, pigs, foxes, hares and deer, and the like, and the writing brush can be divided into various types such as fimbriae, wolves, rabbit writing brushes, and combination brushes according to the hair; in addition, the nylon yarn produced in Japan has fur and is more elastic, so most manufacturers can add some nylon yarn in the writing brush to enhance the elasticity of the writing brush; in addition, for the smooth pen shape of the writing brush, the jute yarn which is a plant material is added at the bottom of part of the pen point to be used as a substrate, so that the appearance of the pen point is more attractive, and the binding of the pen point is greatly beneficial. The brush hair adopted in the existing brush pen is always hydrophilic, the writing effect is continuous and uniform in ink color, a beginner cannot distinguish the stroke movement track, the copying effect can be judged and effectively improved only through the analysis and guidance of a professional teacher, the fact whether a pen is used correctly or not, the problem is what to correct or how to correct cannot be judged by himself, the efficiency is low, and the copying process is dull and boring. There is a need for a writing tool capable of displaying the trace of the writing brush moving, especially the trace of the tip of the writing brush, which is convenient for the teaching demonstration and copying practice of the painting and calligraphy.

When the writing brush head is in a using state, namely a wetting state, namely in an ink dipping or water dipping state, as long as the height difference exists between the brush hairs at the end part of the writing brush head, the brush head is regarded as forming a brush point. The brush hair at the end of the pen point has height in a dry state, and generally has height difference in a wet state, and has a pen point. When the length or height of the brush tip is uniform in the dry state, the height of the tip may be different from the actual length due to inclination or bending of the brush bristles in the wet state, resulting in a height difference, thereby forming a tip.

Detailed Description

The formation of the writing brush calligraphy effect can be divided into two stages: 1. the writing brush is better contacted with the surface of the paper, and the ink is left on the surface of the paper to form a skeleton of the handwriting; 2. the ink flows under the action of self gravity and paper absorption force, and an ink diffusion effect is formed. (Chenhaiqiang et al. brush calligraphy simulation based on pen-paper-ink physical attributes [ J ]. computer aided design and graphics bulletin, 2012,24(9): 1134-1138.). This is to achieve firstly a good adsorption of the ink on the brush hairs.

In the invention, the control of the ink absorption capacity and the ink absorption area distribution of the pen hair is realized by controlling the hydrophilicity, hydrophobicity or hygroscopicity of the pen hair, and specifically can be realized by controlling the parameter contact angle or moisture regain, wherein the smaller the contact angle or the greater the moisture regain, the better the ink absorption capacity is, and the larger the contact angle or the smaller the moisture regain, the poorer the ink absorption capacity is. Under the guidance of the concept, the hydrophilic and hydrophobic properties of the brush hair are controlled by other similar parameters to further control the ink absorption capacity and distribution of the pen point, for example, the material selection or the brush hair preparation process is controlled by taking the water absorption rate and the water retention rate as the standard, and the measured contact angle or the moisture regain does not fall within the numerical range due to different factors such as the measurement method, the measurement environment, the fiber thickness, the dry and wet state of the fiber and the like, but the purposes and the effects of the invention can also be realized based on the same or similar concepts, and the invention is also included in the scope of the invention.

The contact angle reflects the hydrophilicity and hydrophobicity of the material, and the larger the value is, the poorer the hydrophilicity is, and the stronger the hydrophobicity is; the wetting performance of the material is also reflected, and the difficulty and effect of wetting, diffusion and permeation of the surface when the ink is contacted with the surface of the pen hair material can be represented. The contact angle of the invention can be a static contact angle or a dynamic contact angle; the method for accurately measuring the surface dynamic contact angle and the influencing factors [ J ]. Nabei university bulletin of Nature science edition, 2011,41(5):821-, 2007 "," Cao Xiao Ping, infiltration of fluid on rough solid surface and hysteresis thereof [ D ] Zhongnan university, 2005 "," Liuwen super, Terylene fabric surface treatment effect on water repellency [ D ] Wuyi university, 2005 ", and measurement methods in the cited documents of the above documents, among which Wilhelmy method, intravenous drip method and intercalation method are the most commonly used. All the pen point properties in the same pen point can be determined by the same or slightly different judgment standard and measurement method. The contact angle pairs for several typical fiber materials summarized according to the literature are shown in the table below.

The moisture regain can reflect the water absorption capacity of the pen hair material. Under the conception of the invention, the purposes and effects of the invention can be realized by selecting materials and preparing and designing the pen hair by adopting the actually measured moisture regain, the standard moisture regain, the balanced moisture regain and the official moisture regain, and the invention is all included in the scope of the invention. The standard moisture regain refers to the moisture regain measured after the fiber is placed 24 in the moisture absorption process under the standard state that the temperature is about 20 ℃ and the relative humidity is about 65%. The equilibrium moisture regain is the moisture regain of the fiber when the moisture absorption and release function reaches the equilibrium steady state under certain atmospheric conditions.

1. Technical scheme of pen point

1.1 Overall design

The general idea of the invention is that the pen head contains at least two pen hair materials with enough difference in ink absorption capacity, and the two pen hair materials have certain content enough to form handwriting which can be distinguished by naked eyes when writing and painting. The ink absorption capacity can be characterized by including but not limited to hydrophilicity and hydrophobicity or hygroscopicity, and the content is required to be not less than 1% and 5% as an example. Preferably at least one writing material (component two) having a very pronounced ink repellency is present in order to form clear or substantially clear writing. Products and methods which achieve the objects and functions or effects of the invention as taught herein are intended to be included within the scope of the invention in equivalents or approximations. For example, the present invention is also intended to achieve good ink repellency even when component two is not included, taking into consideration the properties other than hydrophilicity and hydrophobicity and moisture regain, and is also within the scope of the present invention.

The pen point capable of displaying the pen moving track of the writing brush is realized by the following technical scheme, and the pen hair material is selected from the following three components of pen hair materials; wherein the content of the first and second substances,

and (2) component two: the contact angle is more than 70 degrees or the moisture regain is less than 0.6 percent, the content in the pen point is more than 0, and the preference is 1 to 95 percent;

the content difference between at least two components is not less than 5 percent, and the total content of the three components is 100 percent; any of the above components, each independently, may comprise a pen hair material of one or more attributes.

The numerical ranges recited herein are inclusive of the two endpoints unless otherwise specified.

The component one is a strong hydrophilic brush hair material which has better ink absorption capacity and can reach the general use standard of the existing brush pen products, and a continuous or basically continuous inking region can be formed during painting and calligraphy. The second component is a pen hair material with better hydrophobicity, which has better ink-repellent capability, and when the pen head has poor ink-absorbing capability or no ink-absorbing capability, a blank or basically blank ink-free area is formed in the corresponding area. Component three is a moderately hydrophilic writing brush material having a hydrophilicity intermediate that of component one and component two, and which will not form either continuous or substantially continuous inked regions or blank or substantially blank inkless regions.

Through the combined application of the three components, the strokes can present stroke outlines and the difference of the shade and the existence of the difference inside the strokes along the stroke moving track by utilizing the difference of ink absorbing amount of different components in the process of writing and drawing. After ink dipping, the ink absorption quantity of the pen hair has regional difference, so that the ink has regional distribution in the pen hair, and in the writing process, the thick and thin, black and white or gray change corresponding to the ink absorption area is formed on the paper surface along with the slow release of the ink, thereby indicating the pen moving track in the writing process.

By reasonably controlling the content and distribution of different hydrophilic and hydrophobic materials (figures 2-5), the ink can be prevented from sliding and fouling a paper surface due to the fact that ink is difficult to soak strong hydrophobic pen hair materials while the ink area is unevenly distributed.

The pen head at least contains one pen hair material with the component two and at least one pen hair material selected from the component one and the component three. The composition comprises a composition of a component I and a component II, a composition of a component II and a component III, and a composition of three components.

Preferably one, the content of component two is greater than or equal to 5%, more preferably greater than or equal to 10%, and may also be selected from a content such as about 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 60%, 65%, 70% in equal proportions, said about representing ± 1%; it is further preferred that component two has a contact angle of greater than 80 ° or a moisture regain of less than 0.5%, more preferably a contact angle of greater than 90 ° or a moisture regain of less than 0.3%. At this time, component two provided very good ink repellency, showing clear blank tracks. When writing, the pen-moving track with combined effect of black or gray and blank colors can be formed. Contact angles of about 90 °, 95 °, 100 °, 105 °, 110 °, 115 °, 120 °, 125 °, 130 °, 135 °, 140 °, 145 °, 150 ° may also be selected, said "about" representing ± 1 °. When the contact angle is more than 150 degrees, the super-hydrophobic grade can be achieved, and the ink repellency is best.

Preferably, the content of the first component is more than or equal to 5 percent, and more preferably more than or equal to 10 percent; further preferred are contact angles less than 25 ° or moisture regain greater than 14%, more preferred contact angles less than 15 ° or moisture regain greater than 14%. At this time, the ink absorption of the brush hair of the component one reaches a good state, and the ink color track can be written more smoothly.

Preferably, the content of the third component is more than or equal to 5 percent, and more preferably more than or equal to 10 percent; at the moment, the pen-moving track can be displayed more flexibly, and the attractiveness and the interestingness are improved.

Preferably, the content of the third component is more than or equal to 5 percent, and more preferably more than or equal to 10 percent; and the combination of at least two kinds of brush hairs is adopted, one of the brush hairs satisfies 45 degrees and less than or equal to 70 degrees or satisfies 0.8 percent and less than or equal to 5 percent of moisture regain, the other of the brush hairs satisfies 25 degrees and less than or equal to 45 degrees or satisfies 5 percent and less than or equal to 15 percent of moisture regain, and the layering of the painting and calligraphy effect can be increased through gradient change of ink absorption capacity.

Combinations of two or more of the above preferred modes may also be employed.

In the preferable mode, the component content and the ink absorption capacity are independent respectively, and no necessary corresponding relation exists; the optimization can be performed independently of each other.

In the pen head, the pen hairs with different hydrophilic and hydrophobic properties (contact angle characterization) or different hygroscopicity (moisture regain characterization) can be mixed in any mode, and basic mixing units comprise but are not limited to monofilaments, multifilaments with the average diameter not more than 0.1mm, single bundles with the average diameter more than 0.1mm, plane or curved surface hair layers with the average thickness more than 0.1mm and annular hair layers with the average thickness more than 0.1 mm. Wherein 0.1mm is the lowest dimension distinguishable to the naked eye.

In the radial distribution, for example, as illustrated in fig. 2,3, 4, and 5, the component is displayed in black, the component is displayed in gray, and the component is displayed in white. The outline of the nib shown in the drawings is not limited to the outline of the nib of the present invention, and particularly, is not limited to the outline of the nib dipped in ink. The drawings are used for indicating the mixing distribution mode and the relative size of the sizes of different hydrophilic and hydrophobic pen hair materials in the pen head, and the illustrations are not used for limiting the hydrophilic and hydrophobic parameter values, the absolute values of the size values and the size relationship of the absolute values. The mixing manner includes, but is not limited to, blending distribution of monofilaments, blending distribution of multifilaments, blending distribution of single bundles and multifilaments, side-by-side distribution of two adjacent regions (fig. 5f (1) - (4)), distribution of two layers of a shell and a core (fig. 5a (1), fig. 5a (2), fig. 5a (6), fig. 5b (1), fig. 5b (2), fig. 5b (6)), three or more layers (fig. 5a (3) - (4), fig. 5b (3) - (4), fig. 5c), two or more single-strand islands-in-the-sea distributions (fig. 5d (1) - (5), fig. 5e (1) - (2), fig. 5e (5) - (6)), single-strand blend distributions (fig. 5e (3) - (4)), split-type distributions (fig. 5f (6), fig. 5g), and the like, or a combination of the above-mentioned mixing means. The boundary between the two regions in the parallel arrangement may be a straight line, a curved line, or a broken line passing through the center axis of the nib (fig. 5f (1) - (2)), or a straight line, a curved line, or a broken line not passing through the center axis of the nib (fig. 5f (3) - (4)). In the multi-layer distribution, the hydrophilic and hydrophobic properties or moisture regain rates between the layers can also form a gradual distribution, including a continuous gradual change or a gradient gradual change, fig. 5c (3) - (4). The island-type distribution includes a single bundle as an island and a background composed of a continuous distribution of monofilament, multifilament or mixed unit thereof as a background, and the single bundle as an island may be arranged regularly (fig. 5e (5)) or randomly (fig. 5e (4)). The split-type distribution refers to a brush hair layer which surrounds any concentric cylinder position of the central axis of the pen point along the radial direction, contains at least more than two types of brush hairs with different attributes (here, different hydrophilic and hydrophobic attributes are referred, and if the distribution mode is considered by other attribute factors, the content is also corresponding to the distribution mode), and the brush hairs are split into at least 2 isolated regions which are not connected with each other.

For the sake of overall pen tip performance, it is also possible to include different kinds of pen tip materials in the same composition, which have similar ink absorption capacity and differ in pen tip length, cross-sectional diameter and cross-sectional shape of monofilament/multifilament/strand, elastic modulus, spring rate, hardness, etc., including but not limited to geometric properties, mechanical properties. Wherein, the distribution mode of the brush hairs distinguished by a single attribute factor along the radial direction (for example, only considering the hydrophilic and hydrophobic nature factor, the other attributes such as the elastic modulus are not limited in the brush hairs with the same hydrophilic and hydrophobic nature at the moment), or the distribution mode of the brush hairs distinguished by two or more attribute factors along the radial direction (the number of the factors is 2,3 or more than 3), or the distribution mode of any one single-attribute pen hair material in the pen point along the radial direction (i.e. the all-factor standard, i.e. all attribute factors are consistent and are regarded as a single attribute), including but not limited to the blending distribution of monofilaments, the blending distribution of multifilaments, the blending distribution of single bundles and multifilaments, the parallel distribution of two adjacent areas, the two-layer distribution of a shell core, the multi-layer distribution (including the gradual multi-layer distribution), the island distribution, the blending distribution of single bundles, the splitting distribution and the like, or the combination of the above mixing modes.

1.2 preferred mode for displaying handwriting outline track

When the total content of the first component and the third component is less than 100% of the outer surface layer of the pen tip, that is, the second component is contained in the outer surface layer, the side-by-side and separation type hydrophilic-hydrophobic distribution patterns shown in fig. 5 may cause incomplete stroke contour display. The outer surface layer refers to the outermost layer of bristles with a thickness of about 0.1mm in contact with air.

The invention further provides a pen point for displaying the handwriting outline track, which meets the requirements of the component I, the component II and the component III, and the outer surface layer pen hair contacting with air contains at least one of the component I and the component III, and the total content of the outer surface layer pen hair exceeds 50 percent, more preferably exceeds 70 percent and more preferably exceeds 90 percent. This composition enables ink to be absorbed, thereby displaying the stroke contour; the contour line can be displayed continuously or discontinuously according to the content and distribution mode of the second component in the outer surface layer. Most preferably, the outer skin layer does not contain component two, i.e., the total content of component one and component three is 100%. More preferably, the shell has a 100% content of either component one or component three.

1.3 preferred mode of displaying pen point running track

In the nib, the length and the length distribution of the nib material are not particularly limited. All the lengths may be equal or different. When the lengths of the brush hairs in the brush head are not consistent, the maximum brush hair length is the pointed length in the field. In the invention, the part of the brush hair which deviates from the front end by no more than 1mm is all included in the category of the brush hair. When the lengths of all the bristles in the pen point are consistent, the pen point is considered to be absent or completely regarded as the pen point.

The definition of the tip includes only a limitation in length, the tip constituting the tip allows for consistency or difference in properties other than length, allowing for difference in one or more properties including, but not limited to, hydrophilicity and hydrophobicity, moisture regain, fineness, cross-sectional diameter and cross-sectional shape of monofilament/multifilament/single strand fibers, elastic modulus, resiliency, hardness, abrasion resistance, and the like.

The properties of the brush hair of the pen head except hydrophilicity and hydrophobicity can be the same or different no matter whether the brush hair materials in the pen head are equal or unequal (the brush hair exists). For example, in addition to the difference in hydrophilicity and hydrophobicity, the elasticity may be different, and the chemical composition and the length may be different. When the pen point contains two or more than two hydrophilic pen hair materials with remarkable difference of hydrophilic property (preferably simultaneously contains the component I and the component III), the adsorption distribution condition of the ink in the core part can be further adjusted in a diversified way. However, it is more preferable that the pen hair of equal length part is made of the same or similar pen hair material in hydrophilic property.

The invention further provides a pen point capable of displaying the running track of the writing brush tip. The pen point meets the requirements of the first component, the second component and the third component, and the pen point comprises a pen point, the pen point is composed of pen points which deviate from the pen point end by no more than 1mm, and the length of the pen point pen points is greater than that of other non-pen point pen points in the pen point. The content of the pen nib bristles in the pen head is 3-97%, preferably 5-95%.

The components of the pencils may include only one of the first component, the second component and the third component, or any two or three of them. Preferably, the penpoint writing brush hair is made of a single writing brush hair material with hydrophilic and hydrophobic properties. It may also be preferred that the nib be constructed of a single property of the nib material, including, but not limited to, the chemical composition, physical properties, geometric properties, etc., described above. Specifically, the compound is preferably selected from any one of the component one, the component two and the component three, and more preferably selected from any one of the component one and the component two.

The content of the pen nib bristles in the pen head is preferably 5% to 60%, and more preferably 5% to 50%. At the moment, the combination and matching of the length of the brush hair and the hydrophilicity and hydrophobicity are realized, so that the display mode of the brush front track is easily optimized to a greater extent. Too little or too much stroke edge content is not good for distinguishing stroke edge tracks.

The length of the pen point pen hair is larger than that of the non-pen point pen hair, and at the moment, the pen point moving track can be displayed more conveniently. The height difference is preferably not less than 1.5mm, more preferably 1.5mm to 6mm, and still more preferably 2mm to 6 mm. When the length of the outer edge is greater than 60mm, the height difference can be suitably enlarged, but preferably not more than 10% of the length of the outer edge, and more preferably not more than 10 mm.

According to the hydrophilicity difference between the writing tip hair material and the non-writing tip hair material, the writing tip track can comprise ink color display, blank display, color mixing display and other display modes; wherein the ink color shows that the shade change can be distinguished according to the strength of the hydrophilicity. For example: the pen point is displayed by ink color when all components are adopted; when the component two is used in its entirety, a blank display can be substantially achieved, particularly when the contact angle is around 90 ° or higher; when the brush hairs with different hydrophilic and hydrophobic properties in the brush tip are randomly blended and mixed and distributed in the single-filament or multi-filament or single-bundle, the brush tip can be traced into a hybrid display, typically an ink color and a blank two-color hybrid display.

The basic units of the aggregation state of the pen tip bristles and the mixing mode thereof are similar to those of the previous embodiment, including but not limited to monofilaments, multifilaments having an average diameter of not more than 0.1mm, single bundles having an average diameter of more than 0.1mm, flat or curved surface layers having an average thickness of more than 0.1mm, and annular layers having an average thickness of more than 0.1 mm.

When the basic units of the aggregation form of the brush hairs of the brush tip are selected from one or more of single bundles with the average diameter larger than 0.1mm, plane or curved surface hair layers with the average thickness larger than 0.1mm and annular hair layers with the average thickness larger than 0.1mm, the properties of the brush hairs in the single bundles can be the same or different. The wools are preferably the same in physical properties, and more preferably the same in chemical composition and physical properties.

Referring to the distribution mode of the pen hair with different hydrophilicity and hydrophobicity, only considering the length property, the mixing mode of the pen hair with different length (i.e. the distribution mode of the pen hair with non-pen hair) includes but is not limited to the blending distribution of single filament, the blending distribution of multifilament, the blending distribution of single bundle and multifilament, the parallel distribution of two adjacent regions, the two-layer distribution of shell and core, the multi-layer distribution (including gradual multi-layer distribution), the sea-island distribution, the blending distribution of single bundle, the splitting distribution, etc. or the combination of the above mixing modes. Referring to fig. 5, for example, the black area represents the writing brush tip area, the white area represents the writing brush area with the smallest writing brush length, and the gray area represents the writing brush area with the writing brush length between the two areas.

Considering all the properties of the brush hair together, the mixing manner of the brush hair with different properties and the non-brush hair also includes but is not limited to the blending distribution of the monofilament, the blending distribution of the multifilament, the blending distribution of the single bundle and the multifilament, the parallel distribution of the two adjacent regions, the two-layer distribution of the shell and the core, the multi-layer distribution (including the gradient multi-layer distribution), the island distribution, the blending distribution of the single bundle, the splitting distribution, and the like or the combination of the above mixing manners.

Accordingly, when considering only a single factor of the length property, or multiple factors including the length property, or all factors of all properties, the cross-sectional shape of the nib portion includes, but is not limited to, discrete points on the scale of the monofilament diameter, circles, near circles, ovals, semi-circles, segmental shapes, triangles, squares, rectangles, polygons of five and more than five sides, stars, trapezoids, dumbbells, olives, irregular profile shapes, hollow rings, meshes of two or more cavities, double rings, multiple rings (three or more than three circles), scallops, discrete scallops around the central axis of the nib, discrete stripes, or the like, or a complementary shape of the above shapes in the cross-section of the nib. Wherein near circular means that the range of variation in axial diameter does not exceed ± 5% of the mean diameter. Preferably circular, near circular or elliptical with an aspect ratio not exceeding 1.10.

1.4 preferred modes of containing the core

The invention further provides a pen point, wherein in the pen point, the writing brush hairs contained in the peripheral outline of all the writing brush hairs form a core part, the core part is completely wrapped by the adjacent closed hair layer, and the thickness of the closed hair layer, namely the adjacent core layer, is not less than 0.15 mm. The core is also referred to as a cartridge in the present invention. At the moment, the pen point has a shell-core type two-layer structure or a multi-layer structure, the shell-core two-layer structure is formed when the adjacent core layer is used as the outermost layer, and the multi-layer structure is formed when the adjacent core layer is used as the middle layer. The central axis of the core may coincide with the central axis of the nib or may be offset, preferably by no more than 80% in the radial direction (i.e. the ratio of the distance from the centre to the radius of the core). Different degrees of deviation can be used for different painting and calligraphy practice purposes. When the deviation degree is 0 and completely coincides with the deviation degree, the training device is very suitable for the center practice, when the deviation degree is 20% -65%, the training device can be used for the lateral penmanship contact, and when the deviation degree is 65% -80%, the training device can be used for the deviation practice. The deviation degree is higher, and when the deviation degree is more than 80% (not more than 97%), the purpose of displaying the handwriting can be achieved, but the combination of the handwriting and the writing method is not as large as the combination of the handwriting and the writing method.

The length of the nib of the pencil is at least 1mm (defined with reference to the nib) greater than that of the adjacent core, preferably not less than 1.5mm, more preferably not less than 2 mm. For example, the difference in length between the adjacent core layer bristles is about 1.5mm, about 2mm, about 2.5mm, about 3mm, about 3.5mm, about 4mm, about 4.5mm, about 5.5mm, about 2-3 mm, about 2-4 mm, about 3-5 mm, about 3.5-5 mm, etc., where "about" means that the deviation is not more than. + -. 5%. The cross-sectional profile shape of the core includes, but is not limited to, circular, near-circular, elliptical, semicircular, segmental, triangular, square, rectangular, polygonal with five or more sides, trapezoidal, dumbbell, olive, irregular profile shapes, etc., or a complementary shape in the cross-section of the nib.

Preferably, the pen head has a structure with two layers of a shell and a core, the content of the pen nib in the core is 100%, in this case, the core preferably contains the component two in a certain proportion, preferably, the content of the component two exceeds 50% of the core, and most preferably, all the component two is selected from the component two. This tip configuration is well suited for practicing the center-point penmanship, as in example 1, example 2.

Preferably, the writing brush tip is made of a single-attribute writing brush tip material, and is preferably selected from any one of a component I, a component II and a component III; more preferably, the component is selected from either one of the component one and the component two. By single attribute is meant that all attributes including, but not limited to, hydrophobicity are consistent. The preparation is simple. That is, the penpoint writing brush hair is preferably composed of writing brush hairs with the same all properties including hydrophilic and hydrophobic properties, and is selected from a component I with good hydrophilicity or a component II with good hydrophobicity on the basis.

Preferably, the content of the penpoint bristles in the core is most preferably 100%, that is, the core is entirely composed of the penpoint bristles, and a clear penpoint band is formed, and the clear penpoint band can be displayed in ink or blank according to the hydrophilicity and hydrophobicity of the penpoint bristles (such as fig. 2 and 3).

The second example in the embodiment 1 is a shell-core structure, the writing brush tip and the adjacent core layer are respectively made of single-property writing brush tip materials, and the writing brush tip content in the core is 100%; in example 8, the core is a shell-core structure, the core is composed of bristles having different properties in terms of hydrophilicity and hydrophobicity (chemical composition) and length, while the adjacent core is composed of a bristle material having different properties in terms of length, and the content of the bristles in the core is 35% and the content of the bristles in the nib is about 19%.

When the content of the writing brush bristles in the core is less than 100%, the writing brush bristles also contain non-writing brush bristles with the length lower than that of the writing brush bristles in the core besides the writing brush bristles. The bristles in the core may be the same or different from each other in addition to the length attribute. For example, the other properties are the same but different in length, different in elasticity (e.g., the dual purpose of using a soft nib and a short bristle with better elasticity to achieve non-bifurcation of the nib and an elastic writing core), different in hydrophilic properties, or different in any two or more of the foregoing properties. When the core portion contains two or more types of the writing brush materials having different hydrophilic properties, the adsorption distribution of the ink to the writing core can also be adjusted in a diversified manner, but it is more preferable that the core portion uses the writing brush materials having the same or similar hydrophilic properties. One of the preferred methods is that the brush bristles are made of a brush bristle material with the same properties. The preparation is simple only when the length attributes are different; when various attribute differences such as hydrophilicity and hydrophobicity, length, diameter, elasticity, hardness, wear resistance and the like exist, the flexibility of pen point performance can be improved, for example, the pen conveying change is more various, the handwriting control is more stable, the service life is longer, and the like.

Preferably, the content of the writing brush tip bristles in the core is 50-95%, more preferably 80-95%. The pen point display device is beneficial to adjusting the shape of the pen point and the density of the pen point, more flexibly displays the pen point track and increases the diversity of display modes.

For the distribution structure containing the core part, the distribution of the pen point bristles in the pen point corresponds to the distribution of the pen point bristles in the core part, and the cross section of the pen point part in the pen point corresponds to the cross section of the core part.

Considering only the length property, the distribution of the writing tip writing bristles and the non-writing tip core writing bristles includes, but is not limited to, single filament blending distribution, multifilament blending distribution, single-strand and multifilament blending distribution, parallel distribution of two adjacent regions, shell-core two-layer distribution, multi-layer distribution (including graded multi-layer distribution), sea-island distribution, single-strand blending distribution, split distribution, and the like, or a combination of the above mixing manners. Referring to fig. 5, for example, the black area represents the tip area, the white area represents the area with the smallest brush length, and the gray area represents the area with the brush length between the two areas.

Considering all the properties of the above-mentioned bristles, the mixing manner of the bristles with different properties and the bristles with non-sharp cores also includes but is not limited to the blending distribution of monofilaments, the blending distribution of multifilaments, the blending distribution of single bundles and multifilaments, the parallel distribution of two adjacent regions, the distribution of two layers of shell and core, the distribution of multiple layers (including the gradual change type multiple layer distribution), the distribution of islands, the blending distribution of single bundles, the distribution of split type, and the like, or the combination of the above-mentioned mixing manners.

The bristles may be distributed continuously or dispersedly in the core along the radial direction. Wherein the continuous distribution mode includes but is not limited to bundling, planar layering, curved layering, hollow tube, multiple-cavity tube, etc.; the dispersion type distribution method includes, but is not limited to, a blend type distribution, a sea-island type distribution, a split type distribution, a discrete multilayer distribution, and the like, and in the case of the dispersion type distribution, there may be a region which is locally continuously dispersed. The blending dispersion means a mixing mode of taking at least one of monofilament, multifilament with average diameter not more than 0.1mm and single bundle with average diameter more than 0.1mm as a basic unit.

When the writing brush tip is distributed along the radial direction continuously or locally continuously, the cross section wheel shape of the writing brush tip comprises but is not limited to a circle, a nearly circle, an ellipse, a semicircle, a segment, a triangle, a square, a rectangle, a polygon with five sides and more than five sides, a star, a trapezoid, a dumbbell, an olive, an irregular outline shape, a hollow ring, a net with two or more cavities, a double ring, a multiple ring (three or more than three circles), a fan, a discrete fan surrounding the central axis of the writing brush tip, a discrete stripe, or a complementary shape of the cross section of the writing brush tip. Wherein near circular means that the range of variation in axial diameter does not exceed ± 5% of the mean diameter. Preferably circular, near circular or elliptical with an aspect ratio not exceeding 1.10.

2.2 preparation method of different Components of writing brush

2.2.1 preparation of one-component one-stroke Material

The first component is selected from animal hair or human hair, and the corresponding preparation method can adopt the technology known in the field, so long as the limit requirements of the invention on hydrophilicity and hydrophobicity or hygroscopicity can be realized. Including but not limited to CN102745003B, CN105459672A, CN105667123A, CN105500961A, CN105459672A, CN105398259A, CN101531108B, CN202656681A, CN104626794A, CN104442091A, CN102363396A, Liu Yi Hua, etc. the maoyang skills of Jiangxi Hongkong brush making skill [ J ]. folk culture forum, 2013,03 and "Couzhu" brush making process research, using pen as example [ J ]. originality and design, 2012(3):24-29 "and other documents and cited documents, wherein the preparation method and the description or example of the performance of the material are all incorporated into the present invention by reference.

Wherein, the important process for controlling the water holding property of the animal pen hair is degreasing treatment to remove residual animal oil and improve the ink absorption performance. Animal grease (vegetable grease remained on vegetable fibers) can be remained on the animal hair, and if the animal hair is not degreased or the degreasing is not thorough, the ink dipping of the manufactured brush pen is influenced when the brush pen is used, the ink cannot be adsorbed on the Piaohao, or the ink can be adsorbed but is not smoothly discharged; moreover, the pen point has poor firmness during binding because the pen point contains grease, and the pen point is easy to fall off (CN101531108B, bulletin date 2009, 9 months and 16 days). Therefore, in the prior art, a degreasing process is indispensable in the process of manufacturing the writing brush by using the animal hair, so that the hydrophilicity (water retention) of the writing brush is increased, and good ink absorption is realized. The traditional degreasing treatment method of the animal pen hair comprises but is not limited to degreasing methods of artificial degreasing, heating degreasing, natural degreasing in the sun and night dew and the like by chemical substances such as lime water, plant ash, rice hull ash and the like. The above preparation method is particularly suitable for the component-pen hair material of the invention.

The first component of the brush hair can also be selected from the plant raw material sources, and the corresponding preparation method can adopt the technology known in the prior art, including but not limited to the preparation methods in the documents of CN105904877A, CN105751739A, CN105459672A and the like which are all incorporated into the invention by reference. Degreasing treatment is also usually included to remove surface grease or water holding capacity optimization treatment is performed to improve water holding capacity.

In order to ensure the ink absorption capacity, the pen hair material and the chemical fiber can be subjected to hydrophilic optimization treatment to prepare the pen hair material with the component I. The hydrophilicity-optimizing treatment method includes, but is not limited to, a degreasing treatment method, a hydrophilic finishing agent treatment method, a hydrophilic coating application method, a chemical reaction modification method, a plasma treatment method, a fiber structure microporation method, an electrochemical method, an ozone treatment method, an ionic liquid treatment method, a protease treatment method, and the like, or a combination thereof. The chemical reaction modification method includes, but is not limited to, chlorination modification method, bromination modification method, chlorosulfonation modification method, grafting hydrophilic molecular layer method, and the like. The degreasing method includes, but is not limited to, an alkali degreasing method, a heat degreasing method, a sun-and-night exposure method, and the like. References include, but are not limited to, "hydrophilic modification of wool surfaces by ionic liquids/proteases [ J ]. textile bullets, 2010,31(3): 83-87", "lissaxme et al. lipase treatment improves the hydrophilic properties of polyester fabrics [ J ]. textile bullets, 2012,33(4): 91-94", "wuxijun et al. 51-52%, Liu Shutao and the like, a method for improving the moisture absorption performance of polypropylene fibers [ J ]. industrial textiles, 2004,22(6): 35-39%, Zhao Qiang and the like, ozone treatment for preparing hydrophilic polyvinylidene fluoride hollow fibers [ J ]. membrane science and technology, 2011, (02):1-8 ", and the like, and the citations thereof are provided. It should be noted that these documents refer to the hydrophilicity-optimizing treatment method only by way of example, and do not limit the component one to the raw material used in the documents.

The chemical fiber subjected to hydrophilization surface treatment is, for example, a highly hydrophilic fiber disclosed in the prior art, such as CN102733169A, CN100393935A, CN103160952B, CN101363138B, xu guo, preparation and research of a highly water-absorbent fiber [ D ] tianjin industrial university, 2003 "li guxing, research status and application of a highly water-absorbent fiber [ J ] household paper, 2010, (10): 39-41", polyacrylonitrile, modified polyvinyl alcohol and the like listed or prepared.

The more hydrophilic the above-mentioned pen nib material is, the more suitable it is as a raw material of the component one pen nib.

2.2.2 preparation of two-component Brush Hair Material

According to the prior knowledge, the non-degreased animal hair and the plant fiber have stronger hydrophobicity, and the contact angle can reach more than 70 degrees (preferably more than 80 degrees, more preferably more than 90 degrees), so that the material selection requirement of the component of the second-stroke hair can be met. The second component hair material can be non-degreased animal hair, non-degreased human hair or non-degreased plant fiber, as long as the requirements on hydrophilicity and hydrophobicity or hygroscopicity can be met, and other treatment steps can adopt the conventional technical means. For example, the method for removing the dirt adsorbed on the surface of the pen hair material can adopt conventional technical means, including but not limited to, cleaning with clear water or solution, cleaning with solution, ultrasonic cleaning, etc., and will not be described herein again. The invention can fully utilize the characteristic of good ink repellency of the animal hair which is not degreased, and adjust the distribution of the ink in the pen point.

The second component may be chemical fiber with lipophilic organic radical and less hydroxyl, amino, carbonyl and other strong polar radical. Synthetic fibers are preferred, and further preferred. The synthetic fibers such as polypropylene fibers, polyester fibers, polyvinyl chloride fibers, PBT fibers, polyethylene fibers and the like have good hydrophobic property and poor hygroscopicity. Most preferred are polypropylene, polyester or PBT fibres.

After the fiber material which can be used as the pen hair is subjected to hydrophobic modification, the fiber material can be used as the raw material of the component two pen hair as long as the fiber material can meet the requirements of the invention on hydrophilic and hydrophobic properties or moisture absorption and has good ink repellency. The hydrophobization modification method includes, but is not limited to, a general hydrophobization treatment method and a super-hydrophobization treatment method. For example, including but not limited to chemical modification, physical coating, surface roughness enhancement.

Shanghai building materials, 2009,24(6): 1-4'. The description of the hydrophilicity and hydrophobicity in the above-mentioned documents and the cited documents is incorporated herein by reference, together with the summary, processing methods, characterization and analysis methods, etc.

2.2.3 preparation of three-component Brush Hair Material

If the animal hair, human hair or plant fiber which is not degreased can meet the requirements of the invention on the hydrophilicity and hydrophobicity or moisture regain of the component III, the animal hair, human hair or plant fiber can be used as the raw material of the brush hair of the component III.

When the degreasing process for preparing the first component of the brush hair is carried out, parameters such as degreasing time, reagent content, degreasing reagent strength and the like in the traditional process are changed, and the degreasing process parameters including but not limited to low temperature, low concentration and the like are controlled to further condition the degreasing rate, so that incomplete degreasing is realized (compared with the degreasing degree of the prior conventional technology), and the first component of the brush hair can be used as the raw material of the third component of the brush hair as long as the requirements of the invention on the hydrophilicity and hydrophobicity or the moisture regain of the third component are met. The invention can fully utilize the characteristic that the animal hair which is not completely degreased has moderate ink absorbing capacity, and realize the differential distribution of the ink in the pen point.

Viscose fiber, acetate fiber, cuprammonium fiber, spandex fiber, acrylic fiber, nylon fiber (nylon 6, nylon 66), vinylon fiber and the like in the chemical fiber can meet the requirements of the invention on hydrophilicity and hydrophobicity or moisture regain of the component III even if the chemical fiber is not subjected to hydrophilicity and hydrophobicity hydration treatment, and can be used as a brush hair raw material of the component III. Of course, it is also possible to use the above-mentioned components as the raw material of the writing brush hair of component three, if the requirements of the invention are still met after hydrophilization or hydrophobization. Taking the preparation method of the CN102745003B pen hair as an example, when the pen hair is subjected to coarse degreasing at 160-180 ℃, if the degreasing time is less than 0.3-0.6 min, incomplete degreasing can be realized; or omitting a 140-150 ℃ fine degreasing process of upward wool root and downward sharehow, and realizing incomplete degreasing. For example, CN105459672A is hemp wool without water holding capacity optimization treatment. It should be noted that, in the prior art, nylon is also used as a raw material of the brush hair, but nylon has poor ink absorption, so that a large amount of ink marks can not be dropped from the paper when the brush pen is used after being dipped in ink, and nylon hairs can cause the ink to be left in the belly of the brush pen (CN104626794A), so that the brush pen needs to be subjected to hydrophilic treatment to overcome the problem of poor ink absorption capacity, and has good ink holding performance. I.e., used as component one, and not used to indicate the writing brush stroke. The third component of the writing brush is different from the third component of the writing brush in function, and the diversified display of writing brush tracks is realized by using the difference of ink absorption capacity of the nylon material and the ink absorption capacity of the first component and the second component.

The synthetic fiber after hydrophilization treatment can also be used as the pen hair material of the third component as long as the synthetic fiber can meet the requirements of the third component. Preferably hydrophobicized polyester fibers, such as polyester fibers or PBT fibers. For example, after hydrophilic treatment, the moisture regain can exceed 0.8% (chemical method polyester fiber surface modification research [ J ] textile science, 2001,22(04): 257-.

2.3 design of the front diameter and the front length of the nib

The maximum length of the brush hair in the pen point is the length of the tip referred to in the field. In the field, the sharp point is the total length of the brush hair exposed outside the penholder, and the sharp point is not calculated when the root of the brush pen is inserted into the pen tube; the tip diameter refers to the diameter of the thickest part of the brush hair, and generally refers to the diameter of the root of the brush hair. The diameter of the pen point is generally referred to as the front diameter.

The diameter of the tip is not particularly limited, and includes but is not limited to the diameter of the tip of the existing writing brush with the specification, the minimum diameter can be about 3-5 mm, and the larger diameter can be 10mm, 15mm, 20mm, 25mm, 30mm, or even larger. When the diameter of the pen point is larger, the length difference between the length of the pen point end and the lengths of the pen bristles in other areas can have a larger range of variation space.

The invention is not particularly limited in its peak diameter and length and combinations thereof, and any commercially available specifications are included within the scope of the invention. The preferred front diameter is 4-50 mm, the front-out length is 10-150 mm, and the length-diameter ratio of the front-out length to the front diameter is 2.5-7.5, wherein the length-diameter ratio is preferably 3-7, and is further preferably 3-5.5. Sometimes the aspect ratio may exceed 7.5 for special long peaks, but generally does not exceed 9.0, corresponding to an aspect ratio range of 7.5 to 9.0, as exemplified in the table below. The special brush pen allows the front diameter, the length of the front edge or the length-diameter ratio to be out of the range, but the brush pen also can be used for achieving the purpose of the invention based on the inventive concept and belongs to the scope of the invention. Wherein, when natural hair is adopted to avoid sources, the length of the appearance is limited to a certain extent. In this respect, the plant fibers and chemical fibers are more tunable.

Wherein, the peak diameter is less than or equal to 7mm, the length-diameter ratio variation interval is larger, and the optimal selection is 3.5-7; the preferred range of the peak diameter is 8.5 +/-0.5 mm, and is 3-5; the preferred range of the front diameter is 10 +/-0.5 mm, and is 3.5-5; the preferred range of the front diameter is 13 +/-2 mm, and is 3.5-5.5; the preferred range of the peak diameter is 18 +/-2 mm, and is 3.5-4.5; the preferred range of the peak diameter is 25 +/-4 mm, and is 3-4.5; the preferred range of the cutting edge diameter is more than or equal to 30mm, and is 3-4.

Specific examples are shown in the following table:

2.4 control of different combinations of writing brush lengths

The lengths of the pen points and the pen bristles can be equal, and the pen points and the pen bristles can also exist, so that the pen moving tracks can be displayed.

Preferably, the pen point exists, and the pen point moving track can be displayed.

Preferably, the length of the pen nib-writing brush is larger than that of the non-pen nib brush, and at the moment, the pen nib-writing track is more favorably displayed. The height difference is more than 1.5mm, preferably 2mm to 6mm, more preferably 2mm to 5mm, and still more preferably 2mm to 4 mm. When the length of the outer edge is large, particularly larger than 60mm, the height difference can be suitably enlarged, but preferably not more than 10% of the length of the outer edge, and more preferably not more than 10 mm.

2.5 mixing of writing brush hairs

The mixing mode of the pen hair materials with different hydrophilic and hydrophobic properties is related to the expected display mode of the pen trajectory, and particularly the design of the combination of the hydrophilic and hydrophobic properties and the pen hair length is taken into consideration. The distribution of the first component, the second component and the third component can be selectively controlled at certain positions according to different stroke exercise purposes. For example, for the center-point penmanship practice (fig. 6), a shell-core structure is preferred, the core is composed of two components, and the length of the core is further preferred to be higher than that of the shell bristles. For another example, when the writing effect displays the moving track of the whole stroke in a stripe-shaped manner (fig. 9), a fracture type distribution, especially a fracture type with a plurality of isolated layers, can be adopted. For another example, for the distribution of the hydrophilicity and hydrophobicity of the pen hair in a multilayer structure, the length difference and the content ratio of pen hair materials at different positions can be designed in a matching manner, so that the aim of displaying the pen moving track, particularly the pen tip moving track, is fulfilled. The ends of the brush hairs at different positions or the whole root can be bleached and dyed with different colors to remind or mark; for example, when the center of the core deviates from the axial direction of the pen head, the corresponding part of the pen holder can be marked optionally, and the deviation position and the deviation degree of the core are reminded.

Besides the control of the degree of hydrophilicity and hydrophobicity, the matching of the elasticity, strength and other properties of the brush hair material is also required to be noticed, and the conventional technical standard is suitable. For example, wolf hair is made of the hair of the weasel, which is tough and tough, next to rabbit hair. The sheep's hair is made of the fibrous root or tail hair of sheep or sheep, and is soft and easy to be hydrated. Sometimes, the pen is made to be moderate in hardness and softness, so that the pen is also used as a 'mixed hair', namely two different animal hairs are polymerized together and named according to the mixing proportion, such as three-purple seven sheep, five-purple five sheep and the like. References include, but are not limited to CN 105500961A. Polypropylene has excellent elasticity, polyvinyl chloride has good elasticity, acrylic fibers are similar to wool (a name of synthetic wool), polyester has elasticity close to that of wool, spandex has good elasticity, and vinylon has poor elasticity. The addition of nylon bristles has been reported to increase the flexibility of the writing brush.

The mixing preparation method of the pen hair can adopt the prior conventional technology, such as the mixing method in the document CN105564082A, and is incorporated into the invention by reference. When the combined brush is manufactured, the performances and the characteristics of various bristles are properly proportioned, the preparation proportion and the selected materials are reasonable, and the lengths and the contents of the bristles can be accurately calculated to achieve the expected use effect.

2.6 manufacture of writing brush and nib
