In the wave of innovation in the nonwoven fabric industry，printed spunlace nonwoven fabrics have become highly sought - after products, thanks to their unique properties and beautiful pattern designs. Spunlace nonwoven fabric is a type of nonwoven fabric made by interlacing fibers with high - pressure water jets. It features softness, strength, breathability, and absorbency. Printed spunlace nonwoven fabrics, based on these characteristics, are given rich patterns and colors through specific printing processes, and are widely used in various fields such as healthcare, hygiene, home textiles, and fashion.

On - line printing seamlessly integrates the printing process into the production line of spunlace nonwoven fabrics. After the fibers have completed processes such as spunlace consolidation, the printing operation is carried out immediately, followed by subsequent treatments such as drying and winding in a unified manner. This integrated process enables smooth production and greatly reduces intermediate handling, storage, and other links. In contrast, off - line printing first produces the spunlace nonwoven fabric into a finished product in the form of rolls. Then, the rolls are transferred to specialized printing equipment for printing, which requires additional steps such as feeding and unwinding.

The continuous production mode of on - line printing has significant advantages. By reducing the waiting and operation time of intermediate links, production efficiency is greatly improved. It is especially suitable for large - scale production of single - variety orders, enabling rapid and efficient fulfillment of market demands. However, once the on - line printing equipment starts production, if the printing pattern needs to be changed or process parameters adjusted midway, it will lead to a relatively long downtime for adjustments, resulting in certain limitations in flexibility. Although the operation efficiency of a single printing process in off - line printing is also relatively high, due to the need for multiple auxiliary operations such as transporting and clamping the rolls, the overall production efficiency is relatively low. Nevertheless, off - line printing equipment has strong versatility. It can flexibly switch between different printing patterns and processes according to order requirements, making it better suited for small - batch, multi - variety production tasks.

During on - line printing, the spunlace nonwoven fabric is in a wet or semi - wet state right after production, and the fiber structure is relatively fluffy. This is conducive to better penetration of paints or dyes into the interior of the fibers, resulting in a stronger bond between the printed pattern and the nonwoven fabric, making it less likely to peel off. However, in the on - line production process, the production speed is relatively fast, which places extremely high demands on the accuracy of the equipment and process control. Once there are deviations, it is easy to cause quality problems such as blurred printed patterns and inaccurate color registration. Off - line printing can use high - precision printing equipment, such as rotary screen printing machines and flat screen printing machines. These devices can achieve more detailed patterns and more accurate color registration, with high clarity and color reproduction of the printed patterns. However, since the fiber structure of the spunlace nonwoven fabric is relatively compact after production, it may affect the penetration effect of paints or dyes. Special pretreatment processes or specific printing auxiliaries are required to improve the fastness and color vividness of the printing.

The research, development, and integration costs of on - line printing equipment are extremely high. It not only requires the purchase of professional printing equipment but also systematic transformation and debugging of the entire production line to ensure the coordinated operation of each link. However, in large - scale production, due to high production efficiency, the cost of equipment depreciation, energy consumption, etc. allocated to each unit product is relatively low. The investment in off - line printing equipment is relatively more flexible. Enterprises can choose different types and specifications of equipment according to their own needs and budgets, and the versatility of the equipment also expands its application scope. However, in the off - line printing production process, multiple handling of rolls, as well as additional pretreatment and post - treatment processes, will increase the consumption of labor, energy, and materials, leading to an increase in comprehensive costs. Especially in large - scale production, the cost advantage is not obvious.
