Description
PROCESS FOR THE PREPARATION OF A CLEANING TISSUE PRODUCT
FIELD OF THE INVENTION
The present invention relates to a method of manufacturing a cleaning tissue product for cleaning hard surfaces wherein said article comprises at least two layers of tissue having a cleaning composition applied thereto. The cleaning tissue product of the present invention is a dry to the touch product and it should be wetted before use. The product obtained by said process is durable and has a sufficient lathering performance.
BACKGROUND OF THE INVENTION
Cleaning products impregnated with detergent are well known in the art. Known disposable cleaning products for cleaning hard-surfaces are typically“pre-moistened” and pre-loaded, i.e. impregnated with the cleaning composition without subsequent dilution before the wipes are applied to the target surface. "Pre- moistened" articles such as hard surface disinfecting cleaning wipes and nonwoven substrates along with many personal cleansing products are also well known.
One major disadvantage of pre-moistened articles resides in the need to provide a moisture tight package. Otherwise, the article would dry out and loose its effectiveness. Moreover, nonwoven substrates typically used in wet wipes are not or only slowly biodegradable, and they show inferior flushability and disintegration, e.g. when disposed into a toilet or a sewage system. Nonwovens based on synthetic fibers moreover render it more difficult to provide the wipe in the form of rolls where the single sheets are separated by perforations or in the form of folded sheets since synthetic fibers show a much higher resistance to folding, cutting or perforation steps. In addition, nonwovens are much more expensive than tissue paper products.
In recent years, consumers prefer to use substantially dry to the touch cleaning articles for hard surface cleaning rather than pre-moistened, in which case the consumer wets the product prior to use, because of hygiene problems of pre-moistened articles or repeatedly used sponges. These are often referred to as "water-activated" articles.
It is, however, difficult to produce a water-activated cleaning product by known methods presented by the prior art. Application of cleaning composition to the paper article makes the process overall cumbersome which brings about disadvantages in terms of the energy and material consumption.
According to known methods, cleaning composition is mixed with an adhesive composition and said mixture is used to laminate the paper layers, thus a water-activated cleaning article is produced. However, products obtained by said mehtod does not provide foaming as desired and bonding capability of paper layers is reduced.
In view of this prior art, it is one object of the present invention to provide an easily applicable, economic and improved method for the production of a water-activated cleaning tissue paper article suitable for efficiently wiping hard surfaces such as furniture, kitchen appliance, dish washing, windows etc.
SUMMARY OF THE INVENTION
The present invention overcomes the above mentioned drawbacks by providing a process for the preparation of a cleaning tissue product wherein a flexographic printing machine is used for applying a cleaning composition to a cleaning tissue product.
According to one embodiment, a process for the preparation of a cleaning tissue product with a flexographic printing machine, includes applying the cleaning composition from first printing plate cylinder to the tissue layers, applying the cleaning composition from second printing plate cylinder to the tissue layers and applying the cleaning composition from third printing plate cylinder to the tissue layers.
According to one embodiment, a process for the preparation of a cleaning tissue product with a flexographic printing machine, includes applying the cleaning composition from first printing plate cylinder to the tissue layers, applying the cleaning composition from second printing plate cylinder to the tissue layers, applying the cleaning composition from third printing plate cylinder to the tissue layers and applying an ink from at least one printing plate cylinders of the flexographic printing machine to the tissue layers.
