Tissue products are used in every day life. While the demand for printing and writing paper declined over the years, demand for tissue products is growing with rapidly expanding markets in Asia and South America. However, scientific knowledge of tissue manufacturing processes, particularly on dry creping, is scattered and still in its embryonic stage. Intense competition in this industry sector precludes the sharing of scientific knowledge gained by each manufacturer from painstaking experimentation. On the other hand advancements in the understanding of buckle-delamination mechanics, relevant to creping process, are yet to be applied in a rigorous and industrially relevant setting. This proposal seeks to contribute to this task through a systematic modeling and experimental approaches. Fundamental understanding of creping in tissue making using mechanistic models and experiments on lab scale and commercial scale pilot machine is the overarching goal of this project. Development of a validated model built from first principles will be a significant contribution to the knowledge base of Canadian tissue industry. The key strength of this project is in the partners. Forest Product Innovations (leading Canadian not for profit forest products innovator), Solenis Canada (creping chemical supplier) and Kruger products (leading Canadian tissue maker of popular brands such as Purex and Cashmere tissues) are the participating organization contributing significant financial and technical resources to accomplish the goals of this project.********

纸巾产品在日常生活中使用。虽然多年来对印刷和书写纸的需求有所下降，但随着亚洲和南美市场的迅速扩大，对纸巾产品的需求正在增长。 然而，卫生纸生产工艺的科学知识，特别是干起皱，是分散的，仍然处于萌芽阶段。这个行业的激烈竞争阻碍了每个制造商从艰苦的实验中获得的科学知识的共享。另一方面，与起皱工艺相关的屈曲脱层力学的理解的进步还有待于在严格的和工业相关的环境中应用。该提案旨在通过系统的建模和实验方法为这项任务做出贡献。本计画的主要目的是利用机械模型及实验室规模与商业规模的中试机，对卫生纸制造中的起皱现象有基本的了解。开发一个验证模型建立的第一原则将是一个显着的贡献，加拿大卫生纸行业的知识基础。这个项目的关键优势在于合作伙伴。Forest Product Innovations（加拿大领先的非营利森林产品创新者）、索理思加拿大（起皱化学品供应商）和Kruger products（加拿大领先的普雷克斯和羊绒纸巾等知名品牌纸巾制造商）是参与组织，为实现该项目的目标贡献了大量的财政和技术资源。
