Classification and Applicable Fabrics of Cotton Fabric Printing Techniques

The first paragraph introduces the classification and applicable fabrics of cotton fabric printing techniques.

Cotton fabric printing is a common textile processing technique that can achieve different effects through different processes and printing methods. Cotton fabric printing can be mainly divided into four types: water printing, paste printing, reactive printing, and digital printing.

The second paragraph introduces the main components, applicable fabrics, and specific operating techniques of water printing.

The main components of water printing are water, binders, thickeners, emulsifiers, etc. It is suitable for light or white cotton fabric printing. The hand feel is good after printing, and it can be printed with a flat screen printing machine or a manual silk screen printing press.

The third paragraph introduces the main components, applicable fabrics, and specific operating techniques of paste printing.

The main component of paste printing is titanium dioxide, which is suitable for dark cotton fabric printing. The hand feel after printing is slightly harder than that of water printing, so it is necessary to carefully select patterns with large printing areas. The specific operating technique is to use a flat screen printing machine or a manual printing press, which is easy to operate.

The fourth paragraph introduces the main components, applicable fabrics, and specific operating techniques of reactive printing.

The main components of reactive printing are water, reactive dyes, sodium alginate (or starch-based printing paste), etc. The hand feel after printing is softer than that of water printing and paste printing. It is suitable for printing with a rotary screen printing machine, flat screen printing machine, or manual silk screen printing press. The actual operation process is slightly more complicated than that of water printing and paste printing, requiring steaming, washing, drying, and fixing.

The fifth paragraph introduces the main equipment, process flow, and advantages of digital printing.

Digital printing processing adopts the reactive digital printing process for printing, and the main equipment is a digital printing machine. After the required pattern is processed by computer color separation, the dye ink is directly sprayed onto the fabric to obtain the desired pattern. The process flow includes fabric sizing, direct printing, steaming, washing, drying, and setting.
