Compatibility considerations for digitally printed nonwovens

In the production process of digitally printed nonwovens, compatibility considerations are a crucial link. It not only affects the quality of printing, but also directly affects production efficiency and cost.
Compatibility of ink and nonwovens
The ink type directly determines whether the digital printing machine can achieve high-quality printing effects on nonwovens. According to the material characteristics of the nonwovens, it is necessary to select a suitable ink type. Common ink types include active inks, acid inks, dispersed inks, and coating inks. Among them, active inks are suitable for cellulose nonwovens, such as cotton nonwovens; acid inks are suitable for protein nonwovens, such as silk nonwovens. For synthetic fiber nonwovens, such as polyester, nylon, etc., dispersed inks can be selected.
Reactivity of ink and nonwovens
When selecting ink, the chemical reactivity between ink and nonwovens must also be considered. For example, active inks can react chemically with cellulose fibers to form covalent bonds, thereby improving the color fastness and durability of the printing. For some special types of nonwovens, specially formulated inks may need to be customized to ensure good compatibility and printing effects.
Compatibility of equipment with non-woven fabrics

Equipment adaptability
Different models of digital printing machines may have differences in adapting to non-woven fabrics. Therefore, when selecting equipment, you need to fully understand the adaptability and performance characteristics of the equipment. For example, some equipment may be more suitable for printing thin non-woven fabrics, while others are more suitable for printing thick or high-density non-woven fabrics. In addition, the equipment's printing width, printing speed, accuracy and other parameters must also match the production requirements of non-woven fabrics.

Matching of nozzles with non-woven fabrics
As one of the core components of digital printing machines, the performance of nozzles directly affects the printing quality and efficiency. When selecting nozzles, it is necessary to consider the matching of parameters such as nozzle size, inkjet volume, and jet pressure with the non-woven fabric material.
