A kind of screen cloth and weaving method thereof
Technical field
The present invention relates to serigraphy field, in particular, relate to a kind of screen cloth and weaving method thereof.
Background technology
Along with the development of screen printing technique, the width of serigraphy lines is more and more thinner, and good straightness degree to printing lines, to widen little, the height index request such as little that rises and falls more next strict.
Tradition silk screen, in the time that half tone is made, screen cloth grenadine need possess certain angle (22.5 degree, 30 degree, 45 degree and 60 degree etc.) with printing lines, thus causing printing lines region has a certain proportion of anastomose, needs the small opening skewness of strike through.And will address this problem, lines need be parallel to grenadine plate-making.At present, in order to meet the needs of printing to half tone tension force and screen cloth intensity, the wire diameter that screen openings is large is thick, and the thin opening of wire diameter is little, all can not meet the demand of plate-making and printing.And when actual screen printing, warp and parallel have certain crooked.
If can realize the printing of 20-40 micron lines, guarantee simultaneously lines straight with certain altitude requirement, can be by cost 20%, in industry can Spring Festival holidays cost-saving approximately 1,000,000,000 dollars.In order to realize the printing of 20-40 micron hachure, the height of slurry, at 10-15 μ m, can adopt the printing technology of nickel screen electroforming to realize simultaneously, and printing effect the best of nickel screen electroforming.But nickel screen electroforming can not continuous printing, it is high that bulk article continues printing difficulty, simultaneously seriously polluted to environment of the production technology of nickel screen electroforming, what use is precious metal nickel, integrated cost costliness be the more than 5 times of traditional silk-screen process, and current equipment and technology all can not be supporting.
Summary of the invention
The present invention is directed to the above-mentioned technical problem existing in prior art, a kind of screen cloth and weaving method thereof are provided, adopt traditional silk screen to realize, greatly reduce cost and the print request of hachure silk-screen plate, and good straightness degree, widen little, height and rise and fall little.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of screen cloth, comprises the first lines and the second lines arranged in length and breadth, described the first lines continuous arrangement, and in described the first line orientations, described the second lines adopt wire jumper weaving manner to arrange; Or, described the second lines continuous arrangement, and in described the second line orientations, described First Line strip adoption wire jumper weaving manner braiding.
The wire diameter of described the first lines and the second lines is identical or different.
The wire jumper weaving manner of described the first lines or the second lines is arranged and is referred to according to wire jumper braiding in the predetermined space outside every reserved certain space.
A kind of screen cloth weaving method, adopts above-mentioned screen cloth braiding to form, and weaving method is as follows;
1), in the time of screen knitting, the second lines continuous arrangement, the arrangement of the first lines, according to wire jumper braiding in the predetermined space K1 outside every reserved certain space K2, the screen openings of described space K2 width=(two wire diameter of screen openings+the first lines of the first adjacent lines) two first adjacent lines of * N2+, N2 is in K2 width, the disappearance quantity of the first lines, N2 >=1; The wire diameter of space K1 width=(two wire diameter of screen openings+the first lines of the first adjacent lines) * (N1-1)+first lines, N1 is in K1 width, the braiding quantity of the first lines, N1 >=1; Or:
2), in the time of screen knitting, the first lines continuous arrangement, the arrangement of the second lines, according to wire jumper braiding in the headspace K3 outside every reserved certain space K4, the screen openings of described space K4 width=(two wire diameter of screen openings+the second lines of the second adjacent lines) two second adjacent lines of * N4+, N4 is in K4 width, the disappearance quantity of the second lines, N4 >=1; The wire diameter of space K3 width=(two wire diameter of screen openings+the second lines of the second adjacent lines) * (N3-1)+second lines, N3 is in K3 width, the braiding quantity of the second lines, N3 >=1.
Described space K1 and space K3 width are identical or different.
Described space K2 and space K4 width are identical or different.
The beneficial effect that the present invention brings is as follows:
Technical solution of the present invention, on the basis of traditional silk screen establishment, can realize plate-making and the printing of meticulous lines, thereby greatly reduce the requirement of the meticulous lines printing of high-quality mass production and the dependence to special typographies such as electroforming nets, thereby reduce the printing cost of the meticulous lines of high-quality, simplified typography.
Accompanying drawing explanation
Fig. 1 is a silk screen schematic diagram in screen cloth;
Fig. 2 is the weaving method schematic diagram of the first lines in screen cloth provided by the invention;
Fig. 3 is the weaving method schematic diagram of the second lines in screen cloth provided by the invention.
The specific embodiment
Below by reference to the accompanying drawings technical scheme of the present invention to be described further.
Shown in Fig. 1, be one of them silk screen schematic diagram that in screen cloth, the lines of arrangement form in length and breadth, the distance L between lines is called screen openings, and the diameter D of lines is called silk screen wire diameter.
Screen cloth provided by the present invention, comprises the first lines 1 and the second lines 2 arranged in length and breadth.When the first lines 1 continuous arrangement, in the first lines 1 direction, the second lines 2 adopt the braiding of wire jumper weaving manner.Or when the second lines 2 continuous arrangement, in the second lines 2 directions, the first lines 1 adopt the braiding of wire jumper weaving manner.The wire diameter of the first lines 1 and the second lines 2 is identical or different.When the second lines 2 continuous arrangement, the first lines 1 are according to often reserved certain space K2, wire jumper braiding in predetermined space K1.When the first lines 1 continuous arrangement, the second lines 2 are according to often reserved certain space K4, wire jumper braiding in predetermined space K3.
The weaving method of above-mentioned screen cloth provided by the present invention, as shown in Figure 2 and Figure 3, specific as follows;
1), in the time of screen knitting, when the second lines continuous arrangement, the arrangement of the first lines, according to wire jumper braiding in the predetermined space K1 outside every reserved certain space K2, the screen openings of space K2 width=(two wire diameter of screen openings+the first lines of the first adjacent lines) two first adjacent lines of * N2+, N2 is in K2 width, the disappearance quantity of the first lines, N2 >=1; The wire diameter of space K1 width=(two wire diameter of screen openings+the first lines of the first adjacent lines) * (N1-1)+first lines, N1 is in K1 width, the braiding quantity of the first lines, N1 >=1; Or:
2), in the time of screen knitting, the first lines continuous arrangement, the arrangement of the second lines, according to wire jumper braiding in the headspace K3 outside every reserved certain space K4, the screen openings of space K4 width=(two wire diameter of screen openings+the second lines of the second adjacent lines) two second adjacent lines of * N4+, N4 is in K4 width, the disappearance quantity of the second lines, N4 >=1; The wire diameter of space K3 width=(two wire diameter of screen openings+the second lines of the second adjacent lines) * (N3-1)+second lines, N3 is in K3 width, the braiding quantity of the second lines, N3 >=1.
In embodiments of the invention, N1=N3=10.
The various embodiments described above are only for the present invention is described, but and are not used in the protection domain that limits claim.Every equivalents of carrying out on the basis of technical solution of the present invention and improvement, all should not get rid of outside protection scope of the present invention.
