How To Improve Sublimation Textile Printing?
How To Improve Sublimation Textile Printing? we’ve to pay a lot of attention to some points as below:
Sublimation transfer ink is that the key material of sublimation transfer technology principally by disperse dyes, connecting materials, solvents and a tiny low quantity of additives. Dyes ought to have sensible sublimation exchangeability and porousness. And reached an explicit degree of fastness indicators, mass of 230 ~ 380, sublimation temperature of one hundred eighty ℃ ~ 240 ℃ unremarkably used transfer printing dyes ar anthraquinone dyes, group dyes, and ion dyes then on.
The association material to the dye with a tiny low affinity, simple to unharness dye gas, and also the applicable printability, preservation and thermal transferability, unremarkably utilized in the association material for the low viscousness of alkyl polysaccharide, alkyl polysaccharide (EHEC), long oil changed synthetic resin than on. unremarkably used solvents are turpentine, terpineol, high boiling alkanol, alkane, cellosolve then on.
(B) Temperature and time
The sublimation transfer method needs temperature management within the vary of one hundred eighty ℃ ~ 230 ℃, the time is concerning ten ~ 30s, whereas listening to the affordable allocation of temperature and time.
Pressure is additionally one in every of the necessary parameters of the sublimation transfer method. for instance, if the pressure is just too tiny, the gap between the material and also the paper is giant, the yarn is spherical, the ink gas molecules impinge on the air and escape, leading to poor printing result, whereas the ink is additionally simple Infiltration, lines thicker, exploit the pattern, pattern blurred, visual effects worse.If the pressure is suitable, the yarn is flat and also the paper between the gap between the suitable paper, the transfer coloring result is sweet, clear lines, swish lines Fine: If the pressure is just too giant, it’s simple to supply deformation, fluff and serious material morphological changes and different problems, leading to rough and color rendering and different shortcomings. Therefore, the management of the transfer pressure on the written pattern, clear pattern, visual effects are terribly essential.
In addition to ink, temperature, time and pressure can have an effect on the standard of sublimation transfer printing, the particular production method there are some things ought to have our attention. First of all, the selection of paper, stable quality, high believability of the provider is that the initial alternative for printing enterprises, during this regard, Our company has become the primary alternative for several enterprises, word of mouth is clear to all or any.
Secondly, it’s necessary to understand that the colour of the dye ink before the transfer (the pattern on the paper before heating and pressing) and when the transfer (the pattern transferred to the fabric) is incredibly totally different, and also the general dye ink appearance Dark and uninteresting, hoping on concerning two hundred ℃ heat to revive true color, so the assembly of pre-production proofing is critical.
Finally, the thermal transfer, to make sure that the new pressing surface, paper and substrate surface shortly close, there’s no gap, otherwise, there is also transfer graphics blurred development.
We are a sublimation paper professional supplier. Our company can supply any need for sublimation transfer paper, sublimation ink, printer, Epson ink, heat transfer paper, Roll calendar machine for textile printing!
