Composition for printing on textile materials of cellulose or polyamide fibers that imitate pearl effect

 

(57) Abstract:

Usage: in the field of dyeing and finishing production and, in particular, when printing textile materials. The essence of the invention: composition for printing, imitate pearl effect, does not contain pearlescent pigment, consisting of an aqueous anionic dispersion of a polyurethane based on polyester diisocyanate and chain extension, representing neutralized with triethylamine, the reaction product oxyalkylene xylitol with maleic anhydride (30%) 41,1-53,8%, glicazide 5.5 to 7.3 per cent, ammonium chloride of 0.5-0.7%, ammonium dvuhromovokislyj of 0.1-0.2%) and polyvinyl alcohol (10%) the rest is up to 100% . Fabric type specified composition, dried and subjected to heat treatment at 150°C for 3 minutes Get the picture, different brilliance, which varies depending on the lighting from the matte to sparkly. 9 table.

The invention relates to the finishing of the textile industry, namely to the composition to obtain the pearl effect in the printing of textile materials.

Known of the finished composition of firms "TÜBINGEN" and "Lamberti" to get pearlescent effect under tegument. Firm Merck (Germany) produces pearlescent pigment called iriodin.

Regardless of the produced forms of technology for producing pearlescent effect is the same: printing, drying, heat setting hot air at 150aboutC for 4-5 minutes

The disadvantage of these compositions is its build-up on the working bodies of the printing machine, and a very limited shelf life.

The closest to the technical nature of the claimed invention is a composition for printing a pearl pigment or a special glow "Flitter", containing, g/kg:

Dialogue it lies in the range 1-100 μm, comprising preferably 60 μm, and the second 100-1000 microns.

Pearlescent pigment is a transparent colourless leaflets with smooth surface and high refraction of light. He gives the surface to be coated, pearl or pearl luster.

In the textile industry uses a pigment, a raw material for which is mica coated with titanium dioxide in conjunction with the relevant mechanical and physical properties. Pearl pigment obtained by coating a thin layer (50-150 nm) titanium dioxide particles of mica thickness of 200-500 nm and a length of 3-150 MKN. Pearly luster of the pigment is the result of lithocholate shape of its particles.

The conventional printing technology: printing, drying and fixing effect by education printed fabric with hot air at 150aboutC for 5 minutes But the process of printing composition containing a special pigment that mimic nacre and creating a shimmering effect, accompanied by a number of difficulties associated with the presence of the pigment in the printing ink.

As pearlescent pigment is a mica particles certain that the e unimpeded passage of the pigment through a sieve.

The particle size sequin much greater than the particle size of the pearlescent pigment, which leads to even greater difficulties printing technology. First of all, you need to use a special screen fabric for templates with fairly large holes. However, the use of these templates will not preclude clogging and clogging" pigments. In addition, the presence of pigment in the printing ink reduces the adhesion of the polymer binder for textile material, of which the effect is not durable. When printing with glitter effect is even less resistant to physico-mechanical shocks: friction, washing is peeling, adfilternone pigment from the surface of the printed material.

The purpose of the invention is improving the sustainability pearlescent effect to the dry friction, the exception pigment and simplifying the structure and reducing the rigidity of the printed fabric.

This objective is achieved in that the composition to achieve the effect of containing the binder composition contains pearlescent pigment, and the effect is created by the composition of the three polymers is polyvinyl alcohol, gocasino and anionic aqueous dispersion of a polyurethane based on polyester, diisocyanate and ugly maleic anhydride.
