Surface Treatment Of Pre Printed Fabric For Inkjet Printing

Inkjet printing is a non-contact printing method, which is characterized by no need of plate making, high utilization rate of dyes, short production cycle, low cost of small batch, high quality and green environmental protection.

But inkjet printing also has its shortcomings, for example, the color is not deep enough to print special colors.

The surface treatment of printed fabric is very important. Ink jet printing only needs to be colored on the fabric surface. The fabric structure determines the surface structure of the fabric, thus affecting the ink jet printing effect. The fabric with high density is lighter than the fabric with low density.

From the purpose of fabric surface treatment, the acid, base and catalyst needed to dye the dye can not be added to the components of the ink.

There are also certain requirements for the fineness of the pattern, which prevents ink droplets from infiltrating on the fabric. On the one hand, it can reduce the discharge of waste water and pollutants, and on the other hand, improve the ink jet printing effect.

The process flow is cotton fabric, sizing, drying, ink jet printing, drying, steaming and washing.

Different surface treatment processes

The influence of K/S value is also different. Proper sizing process is the key to improving the color depth and brightness of inkjet printing.

Processing flow: fabric to normal pressure plasma modification, ink jet printing, drying, baking, and finished products.

Plasma treatment has a certain timeliness, combined with inkjet printing machine, can achieve continuous production.

Ink jet printing is a technology that endows fabric with color and pattern. Processing the surface of fabric printing can not only improve the ink jet printing effect, but also reduce the dosage of chemicals, so as to achieve the purpose of reducing energy consumption, water consumption and waste water COD.

The quantitative single side surface treatment technology only deals with the printing surface of fabrics, and applies quantitative inkjet printing chemicals according to the printing effect.

At this stage, we should develop corresponding fabric surface treatment chemicals, processes and equipment for fabric structure, dyestuff type and inkjet printing equipment.
