Date：2024-02-01 From：Star Color
Non-woven water-based ink is an environmentally friendly, efficient and low-cost printing material, which is widely used in the printing of non-woven materials.Water resistance, friction resistance and weather resistance are important indexes to evaluate the performance of non-woven water-based ink, which is of great significance for the preservation and use of printed matter.In this paper, the water resistance, friction resistance and weather resistance of
non-woven water-based ink are studied in detail to provide reference for non-woven printing industry.
Water resistance of non-woven water-based ink
Water resistance definition
Water resistance refers to the ability of the coating formed by non-woven water-based ink on the surface of the printed matter to maintain its original properties when subjected to the action of water.Good water resistance ink can form a dense coating on the surface of the print, prevent moisture penetration, and keep the print dry and clear.
Influencing factors of water resistance
The water resistance of non-woven water-based ink is affected by many factors, including ink composition, formula, production process,etc.Among them, the selection and ratio of pigments, binders and auxiliaries have an important effect on water resistance.In addition, the drying temperature and time in the production process will also affect the water resistance of the ink.
Water resistance improvement measures
In order to improve the water resistance of non-woven water-based ink, the following measures can be taken:
Select pigments and binders with good water resistance;
Optimize the ink formula, adjust the proportion of additives;
Control the drying temperature and time in the production process to ensure that the ink is fully dry;
The use of post-treatment technology, such as coating treatment, to improve the water resistance of printed matter.
Friction resistance of non-woven water-based ink
Friction resistance definition
Friction resistance refers to the ability of the coating formed by non-woven water-based ink on the surface of the printed matter to maintain its original properties when subjected to friction.The ink with good friction resistance can form a strong coating on the surface of the print, preventing friction from causing the surface of the print to wear or fall off.
Influencing factors of friction resistance
The friction resistance of non-woven water-based ink is affected by many factors, including ink composition, formula, production process，etc.Among them, the hardness of pigment and binder has an important influence on the friction resistance.In addition, the drying temperature and time in the production process will also affect the friction resistance of the ink.
Friction resistance improvement measures
In order to improve the friction resistance of non-woven water-based ink, the following measures can be taken:
Select the pigment and binder with good hardness;
Optimize the ink formula, adjust the proportion of additives;
Control the drying temperature and time in the production process to ensure that the ink is fully dry;
The use of post-treatment technology, such as coating treatment, to improve the friction resistance of printed matter.
Weather resistance of non-woven water-based ink
Definition of weather resistance
Weather resistance refers to the ability of non-woven water-based inks to maintain their original properties when subjected to natural environmental factors (such as light, temperature, humidity, etc.).Inks with good weather resistance can maintain the clarity and color brightness of printed matter in various natural environments.
Influencing factors of weather resistance
The weather resistance of non-woven water-based ink is affected by many factors, including ink composition, formula, production process，etc.Among them, the stability of the pigment has an important effect on the weather resistance.In addition, the drying temperature and time in the production process will also affect the weather resistance of the ink.In addition, natural environmental factors such as light, temperature, humidity, etc., will also affect the weather resistance of the ink.
Measures to improve weather resistance
In order to improve the weather resistance of non-woven water-based ink, the following measures can be taken:
elect pigments with good stability;
Optimize the ink formula, adjust the proportion of additives;
Control the drying temperature and time in the production process to ensure that the ink is fully dry;
The use of post-treatment technology, such as coating treatment, to improve the weather resistance of printed matter;
Pay attention to the impact of natural environmental factors on printed matter, such as avoiding direct light, maintaining appropriate temperature and humidity.
In this paper, the water resistance, friction resistance and weather resistance of non-woven water-based ink were studied in detail.By understanding the influencing factors and improvement measures of these properties, it can provide a useful reference for the non-woven printing industry.With the improvement of environmental awareness and the continuous development of green printing technology, it is believed that non-woven water-based inks will play a more important role in the future printing industry.
