Description
Technical field
The invention belongs to digital ink-jet printed fields, and in particular to a kind of high stability digit printing reactive dye ink and
Preparation method.
Background technique
Digital ink-jet printed technology be with the continuous development of computer technology and a kind of collection computer number for gradually forming
According to the product for the modern science and technology application that processing, precision machinery, photoelectric information technology are integrated.For the digital ink-jet of textile
Printing technique starts from the 1970s, completing the transformation from technology model to production application the nineties.Textile is digital
Ink-jet printed technology gradually substitutes in the whole world traditional by its apparent green printing technique and unique stamp mode
Printing in textiles technology.
After 2000, the digital ink-jet printed technology of textile is rapidly developed, and centre experienced from being mainly used for spinning
It knits drawing a design to small lot production for early period of printing and dyeing and arrives the transition process of large-scale production again.Then, textile is digital ink-jet printed
Gradually penetrate into the multiple fields such as clothes, home textile, automobile decoration, design, advertisement, personalized customization, on-line shop.Last decade, the whole world
Almost double about every two years for the digital ink-jet printed amount of textile, presents the situation of accelerated development.Currently, it is digital ink-jet printed
The ratio of China's textile printing industry has been up to l0% or so.
Ink determines digital ink-jet printed weaving quality as the digital ink-jet printed basic consumptive material of textile, quality
Amount.Currently, China's textile is digital ink-jet printed, with ink overall quality, also there is a big difference compared with same kind of products at abroad, mesh
There is corresponding product in the preceding country, but due to being influenced by correlated conditions such as raw material, technologies, with same kind of products at abroad in quality phase
Difference is a lot of, can not replace imported product, the supply of raw material is also restricted, and price can not also reduce, and printing and dyeing mill's cost can not yet
Decline.Domestic similar product price is compared with import ink, without too big competitive advantage.Wherein, it is used for high-speed digital ink-jet
The high-end ink technology such as stamp is almost external (American-European, Japan and Korea S) monopolization.Above-mentioned, becoming, which influences China's digit printing industry, popularizes
With the major obstacle of development.
Reactive dye ink is one of digital ink-jet printed ink of textile, has ink flow good, saturation degree
The advantages that high, the extensive concern by researcher.
Digit printing is the product of a kind of adjoint this computer technology continuous development and the modern science and technology application of generation, relatively
There are many advantages that are changeable, operating intelligence, production safety environmental protection etc. flexible in application with traditional printing and dyeing.Current digital
In stamp field, active ink is to can be applied to cellulose fibre, protein fibre etc. using a kind of relatively more extensive ink and knit
On object, including the fabrics such as cotton, artificial silk, flax, silk, it can assign polyamide fibre PRINTED FABRIC excellent washing fastness, it can also be with
Instead of chrome dye for woolen dyed, and with to the increasingly strict of production environment pollution and safety problem, active ink by
Gradually replace reduction, mordant dye etc. and further expansion application range.
Existing ink is mainly made of dyestuff, water, surfactant, polyalcohol storage etc., but the fixation in order to guarantee ink
The basic performances such as rate, saliferous rate is difficult to be controlled effectively, and saliferous rate height is unfavorable for the stability of dye ink, storage
Stability is bad, and easily blocks spray head when in use.
