Textile ptinting is a creative process so one must have an eye for the detail when creating printied fabrics. This is because the colour, fixation property and the medium which is used play a pivotal role in the final output. Today most printing related industry use different type of printing and so diferent type of pigment emulsions. While there may be many type of printing, in this issue we would solely focus on pigment printng. This type of printing is a dificult and a messy process, this is because the person who is going to print must form a proper paste or the medium or the vehicle whatever you call it and then he has to create the perfect colour that the client has asked for. While creating a colour may seem an easy task, but it is not, the perfect tone may take hours of hard work to form. So now lets start our journey with the techncal aspect of binder and its printing. followed by the colour shades
For more than four decades, almost all nonwovens required a chemical binder in order to provide any measure of structural integrity. In addition, the binder was called upon to contribute and convey numerous properties that were necessary for the effective performance of the fabric. During this extended period, binders were essentially the weak element in developing fully acceptable nonwoven fabrics. The fibers that were available to the nonwoven industry were the same fibers that were available to the textile and other fiber-based industries; hence, the fibers were fully acceptable. Generally, the binder limited the performance of the nonwoven fabric
J ari Binder- Transparent Binder with high solid content therby good for prnting jari on textile. Pigment Binder: There are many types of pigment binders. they varry in solid content their fixation power, ability to crosslink etc. The ability of a binder depends on the monomers used in it. A simple binder paste would require water the binder, an additive to maintain the alkaline pH and thickener. And if required a softener. After that the pigment is added for the desired tone/shade. when printing one should keep in mind that the print has to be cured or dried properly so that binder hardens and the print has good fastness property.
Adding the pigment is the final step to our journey of forming the binder paste for screen printing. One can say that this step is easy but it is not. Lets start withe primary colours red, blue and yellow these colours cannot be created but the combination of any of these two colours creates secondary colour like green orange and violet.
