Tissue as consumer products is a growing market segment and can capture significantly more value if the performance can be enhanced. Critical functional properties of a tissue, such as bulk, strength and softness are achieved through a manufacturing known as Creping. Despite its critical importance, the science of creping is not well understood. There is very little public knowledge in this area due to secretive nature of tissue business and as well as due to the complex interactions among multiple mechanisms involving creping chemicals, crepe blades, raw pull materials and operating conditions such as doctor blade angle, among others. The proposed research engagement with Forest Products Innovattions, Canada is on understanding mechanics of creping using a combination of mechanistic models and experiments on a real life pilot tissue machine at FPI facilities in Montreal. This proposal is intended to form a basis for long term research program on mechanics of tissue creping with involvement from FPI scientists based in Montreal and Vancouver. Successful completion of this ENGAGE research with FPI Canada is expected to lead to a long term research program in untangling the complexities of the tissue creping and making the underlying science and technology available to Canadian industries in tissue market.

作为消费品的纸巾是一个不断增长的细分市场，如果能够提高性能，可以获得更多的价值。纸巾的关键功能特性，例如松厚度、强度和柔软度， 通过一种被称为起皱的制造工艺来实现。尽管起绉的科学至关重要， 没有很好地理解。由于纸巾业务的保密性质，这一领域的公众知识很少 并且由于涉及起皱化学品的多种机理之间的复杂相互作用， 刀片、原材料和操作条件，如刮刀角度等。 与加拿大森林产品创新公司的拟议研究合作是关于理解力学 在真实的试验卫生纸机上使用机械模型和实验相结合的起皱方法， 蒙特利尔的FPI设施。该建议旨在为长期研究计划奠定基础， 来自蒙特利尔和温哥华的FPI科学家参与的组织起皱的力学。 与FPI加拿大成功完成这项ENGAGE研究，预计将导致长期研究 在解开组织起皱的复杂性，使潜在的科学和技术计划 加拿大工业在卫生纸市场上的可用性。
