Message: I changed my hp dye printer in shirt printer.

Main problem is that ink is not fix on 100% cotton or 50% cotton/ 50% polyester.
I read about ur site plz tell me chemical which i found locally and pretreat the shirt before printing or may necessory after printing 

I am familiar only with techniques used in hand-dyeing, not with the textile industry, but perhaps a few bits of the information that I have will be useful to you.

The problem is that inkjet printers are normally loaded with either disperse dye, which works only on synthetic fibers, or pigment dye, which is not inherently attracted to the fiber. Pretreatments such as Bubble Jet Set can be used to make natural fibers accept inkjet ink in a reasonably washfast manner.

There are many commercially available cationic fixatives for dyes. I don't know what they may be called locally in your location, in Lahore, Pakistan. Different brands whose names I have encountered include Raycafix, Retayne, Dyefix, Fixatol. Their properties may vary, but all are composed of positive ions which bind ionically to the negatively charged ions of most dyes (with the exception of vat dyes and basic dyes).

The Toronto dye company, G&S Dye, has listed instructions on their web site for using their cationic dye fixative, Raycafix, as a prerinse to hold inkjet ink permanently. Their technique is described in their Summer/Fall 2002 newsletter.

Perhaps an adaptation of their technique, using one of the locally available cationic dye fixatives, will be useful to you. You may need to experiment with many different products in this class of chemicals.
