Hands-On Tissue Workshop

Hands-On Workshop for Hygiene Tissue Basics

Hands-On Workshop for Hygiene Tissue Basics

TAPPI and The Paper Science and Engineering School at North Carolina State University bring to you the Hands-On Workshop for Hygiene Tissue Basics. This workshop will give you a complete and systematic review of the basic to complex concepts and processes involved in the manufacturing of hygiene tissue. Lectures will be complemented with hands-on laboratory work, providing participants with theory and practical experience.

This course will immediately improve your knowledge of hygiene tissue manufacturing.

This is an excellent opportunity to:

  • Understand the global hygiene tissue market and what properties drive value in the North American Market.
  • Comprehend the entire process of producing hygiene tissue.
  • Distinguish the differences between fibers and how those differences relate to tissue properties.
  • Recognize challenges in fiber sourcing.
  • Appreciate how unit operations (pulping, refining, creping, drying) affect tissue paper.
  • Run pilot scale equipment to better understand essential concepts and physical processes behind most common unit operations.
  • Get interactive learning with well-experienced faculty.

Workshop Overview

The Hands-On Workshop for Hygiene Tissue Basics has been designed to provide a broad overview of concepts and unit operations involved in the manufacturing of hygiene tissue: Fiber for Tissue, Pulping, Bleaching, Refining, Recycling, Tissue Making and Converting.

The agenda of the workshop includes presentations each morning and hands-on laboratory and pilot-plant exercises every afternoon. Concepts and other course material learned during the morning will be re-emphasized with practice for increased understanding.

The registration fee of $1,890 includes a notebook, a dinner banquet, and lunches.

Who Should Attend

This workshop has been carefully designed for individuals without formal training in tissue manufacturing or new to the industry. This is an excellent opportunity to understand basic concepts, unit operations involved in tissue manufacturing, combining theory and practice.

The workshop is especially beneficial for:
  • Engineers, operators, and technicians who are new to the tissue hygiene industry or have not had formal training in tissue manufacturing.
  • Managers, superintendents, and supervisors who want to understand how unit operations affect tissue manufacturing from a whole-mill system perspective.
  • Controllers, controller’s assistants, and financial personnel who wish to improve their technical knowledge for better cost and financial planning.
  • Sales and service personnel who want to sell their ideas to customers and upper-level management.
  • Research and development engineers and scientists looking to understand the whole manufacturing process to identify opportunities.

Learning Outcomes

After this workshop, participants should be able to:

  • Discuss the entire process for tissue manufacturing.
  • Describe the major types of fibers used in tissue making and its effect on tissue paper.
  • Discuss how unit operations affect fiber and tissue paper properties.
  • Analyze the fiber types of pulping and correlate these with products in the marketplace.
  • Describe the stages and operations of bleaching.
  • Discuss waste treatment and environmental regulations.
  • Identify the major grades and properties of tissue paper.
  • Discuss stock preparation and the approach system.
  • Explain the operation of the wet-end and dry-end of the paper machine.
  • Specify basic converting operations.
  • Discuss the recycling of paper and current challenges in fiber sourcing.


TAPPI will award 3.7 continuing education units (CEUs) to participants who attend at least 80% of the education sessions. The Education Department of TAPPI meets the Criteria for Certification established by the Authorized Provider Commission of the International Association for Continuing Education and Training (IACET), 1620 I Street NW, Washington DC 20006.
