Description
Technical field
The present invention relates to the nylon tape ink dyeing method that impact printer is used, in particular as the ink dyeing method that is the nylon tape of impact printer colour band base material.
Background technology
Colour band is common a kind of printing consumables, and it is the indispensable print components of impact printer, and from the English printer of mechanical impact formula computer impact printer finally the earliest, employed painted carrier all is colour band.The operation principle of colour band is to utilize the interior dot matrix striker of stylus printing machine head or the alphabetical striker in the english typewriter, and the bump colour band is attached to the printing ink that carries on the colour band on the paper, finally produces visual visible print pattern at printing paper.The quality of colour band quality has a significant impact quality and the colour band of print pattern service life, and is directly connected to the service life of print needle.
Colour band can be described as again belt carcass, and it generally includes two layers of meaning, and a kind of is nylon tape behind the Dan Zhijing overstain China ink, does not comprise colour band frame or color ribbon rack, and is another kind of then refer to include colour band frame or the color ribbon rack of colour band or belt carcass.Colour band one word that the present invention uses only has the implication of front a kind of situation.
As previously mentioned, the quality of colour band co-relation printing effect and service life of impact printer to a great extent.For example, without the colour band frame of follow-up inking device, its belt carcass is after consuming a period of time or printing folio, and resulting printing writing can progressively shoal, so that naked eyes can not be identified.The speed of printing writing color light and shade decay mainly contains China ink with colour band length, colour band and measures relevant with the printing ink rate of release.At present, alleviate printing writing color light and shade rate of decay, comprise that with the Main Means that prolongs colour band service life improving colour band contains the China ink amount and lengthen colour band.Although these two kinds of methods are simple, defective is also many.Contain the China ink amount for improving colour band, usually can cause zone face and become wet, so that easily cause adhesive tape, the phenomenon such as tape transport not, but also can cause printing the initial stage writing excessively dark, easily blur, the not first-class problem of writing shade.For lengthening colour band, be subjected to the restriction of colour band frame volume, can only in limited range, lengthen belt carcass, otherwise too much belt carcass holds at ribbon cartridge that can to occur colour band in the zone crowded, increases the colour band running resistance, so that tape transport not.Lengthening simultaneously colour band just merely increases for example consumption of nylon tape and printing ink of raw material, does not produce facilitation for the efficient that improves the unit colour band, has therefore also strengthened production cost.To this, quality how to control colour band becomes the important step that colour band is produced to improve its result of use.
Summary of the invention
Carry the low problem of quantity of ink for aforementioned unit colour band, the nylon tape ink dyeing method that provides a kind of impact printer to use is provided the object of the invention, the colour band that the method is processed not only can improve the quantity of ink that the unit colour band carries, and still can keep the original physical characteristic of colour band.
According to above-mentioned purpose, the nylon belt ink dyeing method for stylus printer that the present invention adopts, its for the nylon tape composition be PA66, the granules of pigments diameter of the printing ink that adopts and viscosity are respectively 5 μ m～15 μ m and 600cps～900cps.This ink dyeing method is first nylon tape to be warming up to 100 ℃～250 ℃, then cloth printing ink on nylon tape.
Optimally, aforementioned nylon belt ink dyeing method for stylus printer, keeping the temperature of printing ink during cloth printing ink on nylon tape is 30 ℃～60 ℃.
The nylon belt ink dyeing method for stylus printer that the present invention adopts, nylon tape is before cloth printing ink, be heated to suitable temperature range in advance, can evaporate like this part moisture content that adsorbs in the nylon tape, make simultaneously the tissue fibers expanded by heating of nylon tape, reach certain fluffy degree, and then strengthen the absorption hold facility to printing ink.On the other hand, before cloth printing ink, simultaneously ink temperature is increased to certain limit after, ink viscosity is reduced, molecular activity is strengthened, and is conducive to improve dispersibility and the penetrating power of printing ink.Therefore, the colour band that adopts nylon tape ink dyeing method of the present invention to obtain, its absorption of inks ability is high, and ink penetration is strong, shows that to contain the China ink amount high and surperficial wet.Experiment shows, utilize this colour band to cut and be made as and be suitable for the finished product that impact printer is used, the rate of release of its printing ink obviously slows down in print procedure, and the writing color light and shade rate of decay of printing is more slow, and the colour band product of therefore producing than existing method has improved service life.
