How to choose non-woven printing ink?

Date: Feb 04 2025 From: Star Color

In the field of non-woven printing, the choice of ink is directly related to printing quality, product performance, and production efficiency. How should one make a decision when faced with the dazzling array of ink products on the market? Below is a detailed analysis for everyone.
How to choose non-woven printing ink?

Consider the characteristics of non-woven fabric

Non woven fabric is a type of non-woven fabric made by combining oriented or randomly arranged fibers through friction, interlocking, or bonding. Its fiber structure is loose, with low surface energy and diverse materials, such as common polypropylene (PP), polyester (PET), etc. These characteristics pose challenges to the adhesion and printing effect of ink on non-woven fabrics. For example, low surface energy can cause ink to be difficult to spread, easily forming water droplets and unable to come into close contact with non-woven fabrics; The differences in chemical properties of different materials can also affect the interaction between ink and non-woven fabric.

Clearly define printing requirements

Printing quality requirements
If you pursue high-precision pattern and text printing, you need to choose ink that can accurately reproduce the design. Printing for high-end non-woven products such as medical supplies packaging, exquisite gift bags, etc. requires extremely high ink color saturation, clarity, and dot restoration. For some products that require relatively low printing accuracy, such as ordinary non-woven shopping bags, disposable non-woven bed sheets, etc., the range of ink selection can be broader.

Product Usage
It is also crucial to consider the ultimate use of non-woven fabrics. For non-woven printing used in food packaging, the ink must comply with food safety standards and be non-toxic and harmless; For non-woven printing of outdoor sunshade products, the ink needs to have good weather resistance, be able to resist the erosion of natural factors such as ultraviolet rays and wind and rain, and not easily fade or age.

production efficiency
In large-scale production, the drying speed and printing adaptability of ink will affect production efficiency. Ink with fast drying speed can reduce waiting time after printing and improve production efficiency; Ink with good printing adaptability can be stably transferred during the printing process, reducing the scrap rate.

Analysis of Common Ink Types

Solvent based ink
Solvent based ink mainly uses organic solvents, which have the advantages of fast drying speed, good ink transfer performance, and bright printing colors. But it also has obvious drawbacks. The volatilization of organic solvents can cause environmental pollution, which is harmful to the health of operators, and its use is restricted in some markets with strict environmental requirements. For non-woven printing scenarios with low environmental requirements, pursuit of fast drying and high color expression, such as some industrial non-woven printing, solvent based ink can be used as an option.

Water-based ink
Water based ink uses water as the main solvent and has the advantages of environmental protection, non toxicity, and no irritating odor, which is in line with the current trend of environmental protection. Its adhesion on non-woven fabric can be improved by adjusting the formula and pre treating the non-woven fabric. The drying speed of water-based ink is relatively slow and is greatly affected by environmental humidity. However, with the continuous advancement of technology, the drying performance and adhesion of new water-based inks have been significantly improved. In the field of non-woven printing with high environmental requirements, such as packaging for daily consumer goods, clothing labels, etc., water-based ink is a good choice.

UV ink
UV ink can quickly cure under ultraviolet irradiation, with extremely fast drying speed and high production efficiency. In addition, the ink film has high hardness and good wear resistance. But the curing equipment cost of UV ink is relatively high, and the ink price is also relatively expensive. For non-woven fabric printing that requires extremely high wear resistance and production efficiency, such as packaging non-woven fabric printing for high-end electronic products, UV ink can play its advantages.
