The Characteristics And Functions Of Different Printing Auxiliaries Are Introduced

Printing auxiliaries are essential materials used in the textile industry to enhance the quality of prints, improve the printing process, and ensure the efficient functioning of printing machines. These materials are specifically designed to aid in the various stages of the printing process, from prepress to post-press.

Then we will introduce characteristics and functions of printing auxiliaries in this article.

Binder agents, also known as binding agents, are materials that are used in printing to bind together the particles of ink or pigments, creating a strong and cohesive layer on the surface of the substrate.

These agents are typically used in the production of coatings, paints, and inks, and are used to enhance the adhesion, durability, and appearance of the printed material. Some of the common characteristics and functions of binder agents include:

1.Adhesion: Binder agents improve the adhesion of ink or pigments to the substrate, ensuring that the printed material remains intact and does not smudge or fade over time.

2.Durability: Binder agents enhance the durability of printed materials, making them resistant to wear, tear, and other environmental factors.

3.Cohesiveness: Binder agents create a strong and cohesive layer of ink or pigments on the surface of the substrate, ensuring that the printed material stays intact and does not flake or peel off.

4.Color fastness: Binder agents can improve the color fastness of printed materials, ensuring that the colors remain vibrant and do not fade over time.

Cross-linking agents are chemicals that are added to printing inks, coatings, and other materials to form a three-dimensional network of chemical bonds between the polymer chains, resulting in a more durable and stable material.

Cross-linking agents are often used in the production of high-performance printing materials that require improved chemical and physical properties. Some of the common characteristics and functions of cross-linking agents include:

1.Heat resistance: Cross-linking agents can improve the heat resistance of printed materials, making them more suitable for use in high-temperature environments.

2.Chemical resistance: Cross-linking agents make printed materials resistant to chemicals and other harsh substances, making them suitable for use in industrial or outdoor applications.

3.Adhesion: Cross-linking agents can improve the adhesion of the ink or coating to the substrate, ensuring that the printed material remains intact and does not smudge or peel off.

4.Scratch resistance: Cross-linking agents can improve the scratch resistance of printed materials, making them more durable and long-lasting.

5.Water resistance: Cross-linking agents can improve the water resistance of printed materials, making them more resistant to water and moisture.

Thickener agents are materials used in printing to increase the viscosity or thickness of inks, coatings, and other materials.

Thickener agents are typically used to improve the coverage and color intensity of printed materials and to prevent the ink from spreading too much on the substrate. Some of the common characteristics and functions of thickener agents include:

1.Viscosity: Thickener agents increase the viscosity of the ink or coating, making it more resistant to flow and spread evenly on the substrate.

2.Coverage: Thickener agents improve the coverage of printed materials, ensuring that the ink or coating is evenly distributed across the substrate.

3.Color intensity: Thickener agents can improve the color intensity of printed materials, resulting in a more vibrant and vivid color.

4.Shear thinning: Thickener agents can exhibit shear thinning behavior, meaning that they become less viscous when subjected to shear forces such as mixing or printing, allowing for easier application and smoother printing.

5.Compatibility: Thickener agents must be compatible with the other components of the printing material, ensuring that they do not interfere with the ink or coating's performance or properties.

Overall, the above three are common printing auxiliaries, mastering some knowledge of products helps to choose suitable products.
