  1. Stenter's printing

  The process of printing floral patterns with dye fastness on textiles with dyes or pigments.

  1. Classification of printed objects

  The main objects of printing are fabrics and yarns. The former attaches the pattern directly to the fabric, so the pattern is clearer. The latter is to print the pattern on the assembly of yarns arranged in parallel, and after weaving, the fabric produces a hazy pattern effect.

  Third, the difference between printing and dyeing

  1. Dyeing is to dye the dye evenly on the textile to obtain a single color. Printing is to print patterns of one or more colors on the same textile, which is actually partial dyeing.
  2. Dyeing is to mix the dye into a dye solution and dye it on the fabric through water as a medium. In printing, the dye or pigment is used as the dyeing medium, and the dye or pigment is mixed into the printing paste and printed on the fabric. After drying, the subsequent treatments such as steaming and color development are carried out according to the nature of the dye or color to make it dye or fix. On the fiber, it is soaped and washed with water to remove the floating color and the paint and chemicals in the color paste.

  Four, pre-processing for printing

  Similar to the dyeing process, the fabric must be pretreated before printing to obtain good wettability so that the color paste can evenly enter the fiber. Plastic fabrics such as polyester sometimes need to be heat-set to reduce shrinkage and deformation during the printing process.

  Five, the method of printing

  According to the printing process, there are direct printing, anti-dye printing and discharge printing; according to the printing equipment, there are mainly roller printing, screen printing and transfer printing. From the printing method, there are manual printing and mechanical printing. Mechanical printing mainly includes screen printing, roller printing, transfer printing and liquid jet printing. The first two applications are more common.

  Flat Screen Printer printing method and its characteristics

  According to the printing equipment, the fabric printing can be divided into: screen printing, roller printing, heat transfer printing, wood template printing, hollow pattern printing, tie-dyeing, batik, splash-dyeing printing, hand-painted printing, etc. Among them, there are two printing methods of commercial importance: screen printing and roller printing. The third method is thermal transfer printing, which is of relatively low importance. Other printing methods that are rarely used in textile production include traditional wood template printing, wax printing (that is, wax proof) printing, yarn tie-dyeing cloth printing, and dye-resistant printing. Many textile printing factories mostly use screen printing and roller printing to print fabrics. Most thermal transfer printing performed by printing factories are also printed in this way.
