What inks and adhesives are used for non-woven printing

Non woven printing mainly uses silk screen ink, which depends on the requirements for water washing. If the requirements for water washing are not high, adhesive, masking white or other adhesives can usually be used. However, if high water wash fastness is required, polyurethane based adhesive or solid slurry should be chosen.

Screen printing ink is a commonly used printing material in the printing process of non-woven bags. Its characteristic is that it can adapt to different types of non-woven materials and maintain the clarity and stability of printed patterns. It is crucial to choose the appropriate ink type based on the requirements for water washing. If the printed pattern only needs to be used in a dry environment or does not require high water washing, adhesive is a good choice. Glue can provide good coverage and ensure that printed patterns have a certain degree of scratch resistance.

However, if there are high requirements for water washing fastness, such as using non-woven bags in frequent washing situations, polyurethane adhesive or solid slurry should be considered for selection. These types of adhesives have better water and chemical resistance, ensuring that printed patterns remain bright and clear even after multiple washes.

Polyurethane based adhesives and solids are commonly used in products that require high durability, such as outdoor products, medical equipment, etc.
In short, when choosing ink and adhesive for non-woven printing, the requirements for water washing and the durability of the pattern should be comprehensively considered. Adhesive paste is usually suitable for situations that do not require high water washing, while polyurethane adhesive or solid paste is the preferred choice to ensure that printed patterns remain in good condition after frequent water washing.
