Osaka based textile major Teijin Twaron has developed its own spinning process for the direct production of aramid pulp.
The new process makes it possible to markedly improve the properties of the pulp. As well as the standard applications, such as gaskets and friction materials, completely new applications are coming into focus, thanks to the high temperature and wear resistance and the excellent electrical and acoustic properties.
Teijin Twaron has recently decided to invest in a large pilot plant in Arnhem. This will have a sufficient capacity for market introduction and will come on stream in 2007. In the meantime the existing pilot plant will supply test quantities for existing and new applications.
High bonding strength
According to Wolfgang Zwilling, Technical Account Manager of the sales department of Friction, Sealing and Paper Applications, a first application is the use in special types of paper for gaskets and friction paper.
“The Jet-Spun Pulp and Fibrids make it possible to make very thin papers that are also strong and very gastight and moreover are also resistant at high temperatures. Due to the ability of building a fine network structure in three-dimensional areas further advantages can be achieved.”
Product and process improvement
The immediate reason for the development of new products is the strong demand from the market for better bonding properties. The responses have been very enthusiastic becausethese new products allow customers to improve both their products and their production processes. The Jet-Spun products are easy to disperse in water and the processing of papers lead to very homogeneous products.
