Mechanics of creping: modeling and experiments

纸巾产品在日常生活中使用。尽管多年来对打印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，关于纸巾制造过程的科学知识，特别是关于干法褶皱的科学知识，是零散的，仍处于萌芽阶段。这一行业的激烈竞争使每个制造商都无法通过艰苦的试验来分享所获得的科学知识。另一方面，与起皱过程相关的屈曲分层机制的理解方面的进展尚未应用于严格和工业相关的环境中。这项建议寻求通过系统的建模和实验方法为这一任务做出贡献。通过在实验室规模和商业规模的中试设备上使用机械模型和实验，对纸巾制作中的褶皱有基本的了解是这个项目的首要目标。根据第一原则建立的经过验证的模型的开发将对加拿大纸巾业的知识库做出重大贡献。这个项目的关键优势在于合作伙伴。森林产品创新公司(加拿大领先的非营利性森林产品创新者)、Solenis Canada公司(CRUPING化学品供应商)和Kruger Products公司(加拿大知名品牌的纸巾制造商，如Purex和羊绒纸巾)是参与组织，为实现该项目的目标贡献了大量的资金和技术资源。

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.
