  • Patent number: 8545861
    Abstract: A fibrous web, in particular tissue web treated with a lotion composition based on an O/W emulsion comprising: (A) at least one oil; (B) an (O/W) emulsifier or (O/W) emulsifier combination; and (C) 6 to 30 weight % of water; wherein the weight % values relate to the total weight of the lotion composition. Since in the above lotion composition the external phase is aqueous, a web treated therewith can easily be wet by water and does not float on the water if it is to be disposed in a toilet.

  • Publication number: 20130220151
    Abstract: An embossing roll for producing fibrous products, has a structurized embossing surface suitable to run against an anvil roll. The structurized embossing surface includes male protrusions or female depressions starting from a base circumferential surface of the roll. The embossing pattern is characterized by the following features: the base areas of selected male protrusions or female depressions in the base circumferential surface are different; the heights or depths of selected male protrusions or selected female depressions in a radial direction of the roll and starting from the base circumferential surface are different; and the angles between sidewall sections and the adjacent base circumferential surface of selected male protrusions and/or female depressions are different.

  • Patent number: 8118972
    Abstract: Toilet paper based on tissue paper being treated with an O/W emulsion comprising at least one non-ionic emulsifier, at least one anionic co-emulsifier, an oil component having a polarity of at least 20 mN/m or a mixture of oil components wherein at least 75 weight-% of the oils constituting the mixture have a polarity of at least 20 mN/m, 6 to 35 weight % of water, based on the total weight of the emulsion, wherein the total amount of emulsifiers and co-emulsifiers is between 4 and 20 weight based on the total weight of the emulsion. Since in the above lotion composition the external phase is aqueous, a web treated therewith can easily be wet by water and does not float on the water if it is to be disposed in a toilet. Moreover, this lotion shows an improved brightness after application on tissue paper, smell and rheology.

  • Publication number: 20090242157
    Abstract: In a tissue paper making machine downstream the yankee-cylinder (9) and upstream the tambour roll (14) a spark detector (13) is provided in the vicinity of the paper web running to the winding-up section (4) in order to detect sparks of glowing fibers or fiber conglomerates, which can be enrailed by the high speed run of the paper web and can be transferred to the paper roll (15) where the sparks are trapped between the paper web windings of the paper mill. Knowledge of this fact offers the possibility to avoid fire in the mother-roll storage.

  • Patent number: 6987181
    Abstract: The present invention relates to a polysaccharide having functional groups, wherein said groups are aldehyde groups formed at positions C2 and/or C3 as well as at position C6 of the anhydroglucose units of the polysaccharide chain. Preferably the polysaccharide is a cellulosic fibrous material whose primary and secondary hydroxyl groups of the cellulose are oxidized into aldehyde groups at least in part by means of TEMPO oxidation and periodate oxidation. The invention also concerns a paper or nonwoven comprising the above polysacaride. According to the invention a relative wet strength of more than 10% can be achieved.
