This changed when joining this technology with a new application – true flushable wipes entered the scene. Meanwhile, these moist toilet tissues take up several meters of shelf space in the respective departments and drugstores.
But the market for moist toilet wipes is limited – in contrast to the huge demand for single-use baby, personal care and household wipes. The trick of making flushable wipes is to lower the nonwoven’s wet strength so it disperses in agitated water. Picture 1 shows the different characteristics of both nonwoven-based flushable and wet wipes.
With the AquaJet, Truetzschler’s spunlacing unit, it’s easy to adapt the web bonding process to produce higher-strength, yet soft nonwovens too. So some two years ago Voith-Truetzschler started trials on making higher-strength wet-laid/spunlaced nonwovens which could compete with conventional baby and personal care wipes found in the market.
