Questions and answers about the Through Air Drying process technology

Q: What does TAD stand for?

If you are looking for more details, kindly visit our website.

A: TAD is the acronym for Through Air Drying

Q: How does the Through Air Drying (TAD) process differ from conventional tissue manufacturing methods?

A: In the Through Air Drying (TAD) process, hot air is used to dry tissue sheets, resulting in softer and bulkier products compared to conventional methods.

Q: What are the key advantages of using Through Air Drying (TAD) technology in tissue production?

A: The TAD technology is a well-established process providing a wide operating window for ultra-premium tissue and towel production. The web is dewatered by vacuum elements in the wet-end. Since there is no wet-pressing and the paper is air-dried, it results in enhanced softness, bulk, and absorbency in tissue products, leading to improved consumer satisfaction and market competitiveness. The C-Former orientations places the long fiber first against the forming wire (draining first) and provide a support for the short fiber. Additionally, since sheet is significantly dryer going into the Yankee cylinder, the operation at the Yankee is less impacted by fines from the white-water system. These process differences are an advantage for both the operation and the end-product quality.

Q: What types of raw materials are typically used in conventional dry crepe tissue paper production?

Mingyang Machinery supply professional and honest service.

A: Softwood or hardwood trees mainly serve as the primary fiber component.

Q: What factors should be considered when selecting or designing a Through Air Drying (TAD) tissue machine for specific production needs?

A: Factors such as production capacity and speed, desired tissue properties, energy efficiency, and cost-effectiveness are considered when selecting or designing a TAD tissue machine.

Q: Are there any challenges or limitations associated with implementing Through Air Drying (TAD) technology in tissue manufacturing, and how can they be addressed?

A: Challenges in TAD technology includes higher energy consumption and equipment costs compared to conventional methods. However, advancements in technology and process optimization can mitigate these challenges. Production output and efficiency of the tissue line, fiber saving, and high retail value of the paper are making the process interesting from a sustainable perspective. Additionally, the process can be integrated with cogeneration, electrical and steam coils heating systems elevating the process to a more sustainable tissue production with potential of a complete fossil-fuel free operation.
