Voith and Trützschler have released a new safety standard for wet-laid spunlaced (WLS) nonwoven machines.
The new standard, VN 3260/TN 0790, is claimed to be a basis for safe production of nonwovens.
It includes a combination of proven standards across paper and textile machines.
With the new standard, producers of nonwovens are ensured of safe and reliable operations of their machines. It becomes a basic prerequisite for expectations to be met in respect of production efficiency and quality.
Voith and Trützschler have developed the manufacturing process for the wet-laid and hydroentangled nonwovens. The materials for the process are produced from machines which consist partly of paper machine components and partly of nonwoven machine components.
This newly developed standard from the two companies, combines safety and standards of both paper and textile machines in a new document and is poised to become a standard for safety requirements for new and upcoming hybrid machines.
Voith says that the manufacturing process for wetlaid nonwovens is similar to producing paper. A suspension that consists of water and fibres up to 40mm in length are passed over a wire, where homogenous fibre mat forms.
Hydroentangling or spunlacing process produces bonded nonwovens, on which texture can be added, if required. Drying and winding of the Nonwovens are done on other machine components.
Voith claims that the new standard has been incorporated by the International Standardization Organization (ISO) as the basis for developing an international standard, so as to achieve greater impact at global level.
Recently, Voith Paper stated that its Advanced Products have achieved higher paper production in the former, press and dryer sections. Products of Voith are claimed to integrate in former, press and dryer sections to reduce operating costs and have been instrumental in increasing production.
