Printing paste

Sodium alginate printing paste

Printing paste is added in the course of printing paste thickening effect of polymer compounds. Before added to the printing paste, generally are soluble in water or in the water fully swelling and dispersion of the hydrophilic polymer thick colloidal solution, or the type of oil/water or water/oil type emulsified paste. To create the printing paste, part of the dye dissolved in the water, another part of the dye is dissolved, adsorption or scattered in the printing of the original paste. The printing paste is the main component of the printing paste, which determines the operation performance of the printing, the surface of the dye to the color, the pattern contour of the smooth finish

1, High quantity of color, saving dyes. The paste viscosity and smooth, good dispersion performance, can make the dyestuff evenly dispersed and accurate fixed position in the fabric must not bleeding, avoid the easy generation when using traditional paste uneven dyeing, color points, flow permeability, thin lines are short and other ills, make pattern outline clear, bright color and can save dyes.

2, High color fastness. The product in the PH value between 5 ~ 13 paste does not occur in the phenomenon of condensation and hydrolysis, resistant to acid and alkali, and electrolyte performance is good, has the strong ability to carry, make dye fixation on fiber through a variety of function.

3, improve production efficiency and product quality.Stick paste viscosity is appropriate, and not at all, the thixotropic performance is high, the modulation of paste, paste dyestuff to carry on the fabric, non-stick printing tools and fabric, effectively avoid the traditional paste in the printing process likely to drag pulp by touch blade not net, towing by touch net, due to be stained with fabric desizing and other ills, which reduces the defect rate, improve the working efficiency and product quality.

4, widely used. This product is mainly suitable for reactive dyes, disperse dyes printing process.In acidic dye, quick sulfur element (la yuan lalanne) dye can reduce the dosage of 50% triethanolamine in use.Available in roller, flat screen and rotary screen printing process.Can be in cotton, wool and polyester/cotton fabric printing.

The printing paste is the main component of the printing paste, which determines the operation performance of the printing, the surface of the dye to the color, the pattern contour of the smooth finish. The main raw material of the printing paste with sodium alginate is mixed with other high molecular compounds.

Based on the characteristics of different fabrics, our company has developed a series of printing paste products with sodium alginate as raw materials.0.0

Method of Use

Active printing method: add proper amount of water to the mixer and start the high speed stirring. Slowly add the algal stamp paste and the anti-stain salt S (or its substitute, in the area with high hardness of water), stir in 30 minutes. Continue adding water, and add baking soda and urea, etc. in turn, and stir until dissolved. The whole process takes about 2-3 hours (related to mixing speed and stirring). Then put it in a storage tank for 4 hours and then add the dye.

Disperse printing method: add proper amount of water to the blender and start the high speed stirring. Slowly add the seaweed stamp paste and stir until well dissolved. The whole process takes about 2-3 hours (related to mixing speed and stirring). Then put it in a storage tank for 4 hours and then add the dye.

Notes:

1. According to the different requirements of technology and fabrics, the proportion of paste making or use can be adjusted in appropriate amount.

2. For the different dyes and printing processes used, the dosage of additives may be increased and decreased as appropriate.

3. After adding Ca2 +, Mg2 +, Fe3+ and other metal ions into the paste, the viscosity will decrease, and the use of plastic drums or stainless steel drums is recommended.

4. Use hot water to beat the paste and paste, which will lead to a reduction in the viscosity of the paste. To cool hot water soluble dye solution (below 40 ℃), to filter into the original paste.
