JP2012214002A - Method for producing screw pine writing brush - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a screw pine writing brush using screw pine (Pandanus odoratissmus) which can attain strength and pliancy of a writing brush inherent to screw pine since not only wild brush feeling but also pliancy inherent to a writing brush of animal hair are required though a hitherto known screw pine writing brush is liked because of resiliency that is characteristic of screw pine hair.SOLUTION: A method for producing a screw pine writing brush comprises: a first step of washing an aerial root of a screw pine tree and thereafter cutting into a predetermined length; a second step of peeling epidermis of the cut aerial root of screw pine; a third step of tying a center part with a string and unravel its right and left by beating into writing brush characteristics different by the right and the left; a fourth step of bending and folding the center part of the aerial root of screw pine tied with the string to align right and left tips of the brush; and a fifth step of setting the aligned tips of the brush, and binding a part becoming a stem of the brush by winding with a thread.

Description

  The present invention relates to a method for manufacturing an Adan brush.

  Adan is an evergreen shrub belonging to the family Acanthaceae in the tropics. Adan brushes are made by using the air root portion of this Adan tree and processing it by drying it by a special method to make a brush handle and hair.

  In the conventional Adan brush, the air root portion was collected and dried to make a brush handle, and the tip portion was tapped to loosen it into a hair portion.

  As a method for manufacturing this Adan brush, there is Japanese Patent No. 4234290 which has already been registered by the applicant.

Japanese Patent No. 4234290

  The problem to be solved is that conventional Adan brushes prefer the elasticity of hair unique to Adan, but not only the rough brush sensation, but also the flexibility that is unique to brushes is required. An object of the present invention is to realize a brush using Adan that can simultaneously realize the strength and suppleness of a brush unique to Adan.

  Claim 1 of the present invention is the first step of cleaning the air root of the tree of Adan and then cutting it to a predetermined length, the second step of peeling the skin of the air root of the cut Adan, and the center part. A third step of tying the left and right sides, unraveling the left and right sides with different brush quality states, a fourth step of bending the loose Adan's air roots with a string, and combining the left and right brush tips; An Adan brush manufacturing method comprising a fifth step of preparing a combined brush tip and winding a thread around a pattern to be bundled.

  According to claim 2 of the present invention, when the brush tips are aligned, the left and right hair portions are arranged by brushing so that the hardly loosened portion is the core portion and the softly loosened portion is the outer peripheral portion. The method for producing an Adan brush according to claim 1.

  According to a third aspect of the present invention, in the third step of loosening the brush tip, after the tip of the brush is hit, the wire brush is used to unravel the brush tip. is there.

  According to a fourth aspect of the present invention, in the third step of loosening the brush tip, the tip portion is dipped in lye containing chlorine and softened. It is a manufacturing method of the described Adan brush.

The present invention has the following effects.
(1) It is possible to realize a brush having different brush elasticity at the brush core and outer periphery.
(2) Adan brush with good writing quality can be realized.
(3) Realize a new design brush with an unprecedented shape.
(4) An Adan brush having both advantages of elasticity and flexibility can be realized.

  It is a figure which shows the air root of the collected Adan.   It is a figure which shows the state which tied the center part with the string and hit left and right.   It is a figure which shows the state which solved the brush-tip with the wire brush.   It is a figure which shows the state which immerses a brush-tip part in ash-containing lye and performs a softening process.   It is a figure which shows the state of the sun drying after the softening process of a brush tip.   It is a figure which shows the state which wound the center of the dry brush with a string, and was bent.   It is a figure which shows the state which bent and brush-matched.   It is a figure which shows the state which wound the thread | yarn around the part used as a handle in the state of writing.   It is a figure which shows the state which determines the length and determines the tip.   It is a figure which shows the state which finished varnishing.

  The manufacturing method of the Adan brush of the present invention will be described below.

1) Collect the air roots of Adan, cut the air roots to about 50 cm (Fig. 1), and peel the epidermis.

2) Tap lightly as a whole, determine the center, and squeeze about 1 cm with a string. (Figure 2)

3) Hit the tip of the brush one by one and comb with a wire brush. (Figure 3)

4) Soften the softened brush tip with chlorine-containing lye. (Fig. 4)
(Put in solution for about 1 hour)

5) Tap the softened brush tip and make it thinner with a wire brush.

6) Dried for about half a day to one day in the sun. (Fig. 5)

7) Wrap the middle of dry air root with Adan's string about 3cm. (Fig. 6)

8) Match the brush tip (hard and soft part) and wind the thread. (Figs. 7 and 8)

9. Determine the length of the tip. (Fig. 9)

10. Apply finish varnish. (Fig. 10)

Claims (4)

  After washing the air roots of the tree of Adan, the first step of cutting to a predetermined length, the second step of peeling the cutaneous air skin of the cut Adan, the center is tied with a string, 3rd step to loosen and unravel the left and right with different brush quality state, 4th step to fold the air root of loosened Adan with a string and tie the left and right brush tips, arrange the combined brush tips, A method of manufacturing an Adan brush, comprising a fifth step of winding a thread around the part to be bundled.   2. When adjusting the brush tip, in the left and right hair parts, the hard loosened part is used as a core part and the soft loosened part is arranged as an outer peripheral part. The manufacturing method of the Adan brush as described.   3. The method for producing an Adan brush according to claim 1, wherein, in the third step of loosening the brush tip, after the tip portion is hit, the wire brush is used.   The method for producing an Adan brush according to any one of claims 1 to 3, wherein, in the third step of loosening the brush tip, the tip portion is dipped in lye containing chlorine and softened.
