Assessments for Spunlace Lines

The high energy consumption of spunlace nonwoven lines is mainly due to water and drying intensive processes, water treatment and high mechanical requirements. The reason for the high energy consumption is the hydroentanglement process, where large quantities of water are formed into water jets under high pressure. This causes the fiber web to solidify. At the same time, the applied water must be extracted in a first step and separated from the fibers in a second step by subsequent drying of the product.

Efficiency improvements can be achieved by optimizing water consumption, water pressure, dewatering, and heat recovery in the drying process and by using energy-efficient technologies.

Spunlace Line Assessment – Measure, Retrofit, Save

Works with any spunlace line – regardless of manufacturer, we measure performance, define upgrades, and guarantee energy savings

The AUTEFA Assessment for Spunlace Lines provides you with a comprehensive analysis of the savings potential of any existing spunlace machine - regardless of brand or manufacturer.

Based on your technical data, our experts calculate theoretical energy savings and determine the expected return on investment (ROI). During an on-site visit, we take detailed measurements of the machine and evaluate key dewatering settings such as vacuum levels, slot width, slot design, leakage points, and mechanical interfaces relevant to a potential retrofit.

We then define optimized process settings and recalculate energy consumption based on a specific product. This analysis results in a guaranteed ROI that is documented in a binding retrofit contract.

The retrofit is performed directly at your facility and typically takes only one to two days. After implementation, we validate the energy savings and help you achieve long-term efficiency gains - across all machine types and manufacturers.

Optimized dewatering with V-Slot Flex System

Smart system upgrade for efficient water removal and drying

The dewatering system of a spunlace machine plays a crucial role in the production process of nonwovens, also in terms of energy consumption. During and after the bonding process, in which water is sprayed through the fibers under high pressure to bind them together, the excess water must be removed. This step is important to stabilize the fiber structure and facilitate drying.

To efficiently remove the water from the material, AUTEFA's patented V-Slot flex system uses pneumatic pressing of the suction bars against the inside of the drum to eliminate leakage. This mechanism enables a significant reduction in energy consumption for the mechanical dewatering process. In our assessment for spunlace dewatering, we not only look at the extraction points inside the drum, but also at the entire dewatering process and define holistic measures to optimize it to the maximum. These measures not only have an effect on the water content and the volume flow required for dewatering, but also reduce the energy required for subsequent drying, which leads to an improvement in overall productivity.
