Abstract
The invention relates to pre-coating solution for digital jet printing for cotton, belongs to the field of fabric printing, and provides the pre-coating solution for the digital jet printing of aqueous ink for cotton textiles. The cotton textiles processed by the pre-coating solution are subjected to jet printing and proper heat treatment to form printing products with clear colors and good wash fastness.
Description
Technical field
The present invention relates to a kind of cotton and use the digit printing pre-coating solution, belong to the weaving chemical field.
Background technology
No matter the tradition stamp is plain net or cylinder, all exist shortcomings such as the technological process of production is long, labour intensity is big, environmental pollution is serious.In recent years, along with development of technologies such as computer, material, information and precision optical machinery manufacturings, Digital ink jet printing technology more and more is subject to people's attention.
With input mediums such as scanner, digital camera, digital cameras, pattern is imported computer with digital form, after the image software processing, again by computer-controlled digital inking printing machine, directly printing ink is ejected on the various fabrics, print out required various patterns, this printing technique is called as digital inking printing.
The digital ink-jet printed technology of textiles is compared with traditional printing technique, and its main advantage is embodied in: stamp fineness height, need not plate-making, and in batches flexibly, can single-piece make, also can produce in enormous quantities; Delivery rate is fast; Can realize the individual electronic business consumption by the internet; Discarded and the waste of no dyestuff and auxiliary agent, without sewage discharge.The tradition stamp need wash the flower version, and the fabric behind the stamp needs washing, soap boiling to remove loose colour, not only causes the waste of dyestuff, auxiliary agent, water resource and the energy, and seriously polluted.
In digital ink-jet printed process, owing to do not contain the dye fixing catalyst in the common aqueous dye ink, ink injects directly on and is easy to imbibition on the fabric, influences the fineness of pattern.Therefore, when carrying out digital inking printing with common ink-jet ink, need fabric is carried out preliminary treatment, it mainly is to prevent ink imbibition on fabric that pretreatment fluid is handled, and improves the wash durability and the light fastness of coating.The quality of a good ink-jet printed product of ink-absorbed coated layer logarithmic code is most important for this reason.
Summary of the invention
Be problems such as water-based fastness difference behind the stamp of solution cotton material surface and easy imbibition, the invention provides a kind of digital jet printing for cotton water-based pre-coating solution, main component comprises: 15~60 parts of resin cations, 15~30 parts of inorganic fillers, 20~40 parts of hydrophilic resins, 10~15 parts of solvents, 0.1~0.5 part of defoamer.
