In order to obtain a clear pattern in the printing of non-woven fabrics(Printed Non Woven Fabric Supplier), in addition to dyes, coatings and necessary additives, an appropriate amount of printing paste is added. The so-called printing paste refers to a polymer compound capable of thickening in a colorpaste. Before adding a color paste, it should generally be dispersed in waterto form a thick colloidal solution having a certain concentration. The colloidal solution is called a printed paste. Its viscosity is much greaterthan the viscosity of the color paste, so it is a kind of substance that increases the viscosity of the solution. The performance of the original paste directly affects the quality and cost of the printed product, so the use of the original paste characteristics and selection of the original paste is one ofthe important links in the printing process.

The original paste should have a good printing effect, that is, it can print a complete and uniform pattern(Biodegradable Nonwoven Fabric Wholesale) under the force of the color paste, and penetrate into the fabric, and must also overcome the seepage phenomenon caused by the capillary effect of the fabric, and ensure the outline of the pattern is clear. This requires that the printing paste has a certain fluidity and can enter the gap of the textile during imprinting without causing permeation. The original system should also have good wettability, hygroscopicity and water repellency. There are some links and contradictions between these three properties. In the original paste use and process control, consideration should be given to the selection and optimization.


The paste should have certain physical and chemical stability after being made into the original paste, so that the originalpaste is beneficial for storage, and does not cause deterioration of skin,mold, odor, etc. during storage; It can withstand the mechanical effects of stirring, squeezing and rolling: it has good compatibility with dyes andchemical auxiliaries, and does not cause hydrolysis, salting out,agglomeration, knife edge and other phenomena. The original paste itself cannot have a pigment or can only slightly have a pigment that has no directin fluence on the fiber, and can be eliminated in the washing process after printing, and does not affect the vividness of the printed fabric. The filmformed on the fabric should have a certain adhesive force and flexibility, soas not to fall off the fabric. However, if the adhesion is too strong, it isnot easy to wash off, which affects the feel of the fabric(Home Textile Nonwovens Vendor). The paste rate ofthe original paste is high, the paste is convenient, the process adaptabilityis wide, the source is abundant, and the cost is low.
