摘要： High bulk tissue webs are processed sequentially through separate calendering and embossing units to optimize the balance between sheet caliper for winding tension and embossing element height for pattern definition, resulting in embossed, high-bulk tissue products with improved embossing pattern clarity. The multiple step converting process enables the use of male embossing elements having a height of about 0.04 inch or greater. The tissue webs have a Residual Waviness value of 12 micrometers or greater, which is attributable to average surface waviness values for the spot embossments being about 30 micrometers or greater.
摘要翻译：通过单独的压延和压花单元顺序地处理高体积组织网，以优化用于卷绕张力的片材厚度与图案定义的压印元件高度之间的平衡，从而产生具有改进的压花图案清晰度的压花，高散装纸巾产品。多步转换过程使得能够使用高度为约0.04英寸或更大的凸形压花元件。组织纤维网具有12微米或更大的残余波度值，其归因于斑点压纹的平均表面波纹度为约30微米或更大。

摘要： A method for making a throughdried tissue sheet is disclosed. The method includes the steps of depositing an aqueous suspension of papermaking fibers onto an endless forming fabric to form a wet web. The wet web is then transferred to a throughdrying fabric such that the wet web has a fabric side in contact with the throughdrying fabric and an opposite air side facing away from the throughdrying fabric. The wet web is routed over a throughdryer to dry the web. The web is then transferred to a Yankee dryer for further drying and is creped from the Yankee dryer to obtain a creped web having a basis weight of about 15.2 pounds per 2880 square feet. The creped web in then calendered in a calendering unit that includes a smooth calender roll and a resilient calender roll. The resilient calender roll has an exterior covering formed of ethylene propylene diene polymer and the creped web is oriented such that the fabric side is disposed toward the resilient calender roll. The finished tissue exhibits improved softness while retaining adequate strength.
摘要翻译：公开了一种用于制造通过干燥的薄页纸的方法。该方法包括以下步骤：将造纸纤维的水悬浮液沉积到环形成形织物上以形成湿网。然后将湿纸幅转移到穿透干燥织物，使得湿纸幅具有与透明织物接触的织物侧和背离透明织物的相对空气侧。湿纸幅通过吹扫器布置以干燥纸幅。然后将纸幅转移到扬克烘缸以进一步干燥，并从扬克烘缸中起皱，得到每2880平方英尺的基重为约15.2磅的起皱网。该起皱纤维网然后在压延单元中压延，其包括光滑的压延辊和弹性压光辊。弹性压延辊具有由乙烯丙烯二烯聚合物形成的外部覆盖物，并且起皱网被定向成使得织物侧朝向弹性压延辊设置。成品组织在保持足够的强度的同时显示出改善的柔软度。
