The present invention relates to a nonwoven fabric and the production thereof. More specifically, the invention relates to a dispersible and biodegradable nonwoven fabric comprising a web prepared using a wet lay forming process. The process involves forming a web from the aqueous suspension on a wire support, hydroentangling and drying the web. The web can be provided with a high quality hydroembossed pattern, which remains even in wet wipes prepared from the material.

Nonwoven fabric and the production thereof

The invention relates to a manufacturing process of equipment for use in the production of nonwoven fabrics and paper products. According to the present invention, a sleeve for an embossing roller is produced using additive manufacturing, specifically 3D printing. These technologies permit the preparation of pattern-forming and dewatering details in the sleeve in a single operation. The dewatering properties may thus be optimised for the selected pattern, resulting in uniform dewatering tailored for the pattern. Preferably, the technique used is stereolitography.

3D printed sleeve and a method for preparing thereof

Nonwoven fabric manufacturing line, which comprises a forming device for forming a fibre web on a moving web-forming base and a spunlacing device for reinforcing the web. Further, the line comprises at least one first drying device for drying the web and a calender for forming patterning in the web. The manufacturing line comprises at least one second drying device for drying the calendered web, which second drying device is located after the calender in the direction of travel of the web.

Manufacturing line for nonwoven fabric

The present invention relates to a method for producing a nonwoven fabric. The method according to the invention comprises forming a nonwoven web using a wet lay forming process, hydroentangling the web and providing the web with a high quality hydroembossed pattern. The invention also concerns a nonwoven fabric exhibiting a three dimensional pattern, which remains even in wet wipes prepared from the material.

Method for preparing a nonwoven web

A nonwoven is provided having a pattern displaying at least two groups of areas having different optical properties distinguishable to reading and decoding equipment. The pattern may be arise from differences in the microstructure of the web. The nonwoven material may have an embossed pattern having a basic, static component and a dynamic component which varies within a given length of the nonwoven web. Further, a method is provided for obtaining information from a nonwoven web, comprising observing the web surface using an optical reading device, collecting data based on differences in optical properties in the web surface, storing in a digital memory a pattern based on the collected data and comparing the stored pattern to a collection of previously stored patterns.
