What Is The Role of The Creping Blade And What Impact Will It Have on Toilet Paper?

The creping blade is often used on the surface of the paper machine drying cylinder to remove the toilet paper attached to the drying cylinder. The creping blade uses the speed difference between the paper roll drying cylinder and the Yankee drying cylinder to complete the wrinkling.

In the production process of toilet paper, the material of the doctor blade, the angle between the tangent line of the doctor blade and the drying cylinder, the contact position between the blade and the drying cylinder, etc. will have an important impact.

(1) The impact of the material of the creping blade on the quality of toilet paper: The higher the quality of the doctor blade material, the better the quality of the toilet paper. Different materials have different effects on the texture and surface cleanliness of toilet paper. The higher the quality of the doctor blade, the better the quality of the toilet paper produced.

(2) The wedge angle of the creping blade: The wedge angle of the doctor blade will affect the appearance of the toilet paper. If the wedge angle is too large, the contact surface between the creping blade and the drying cylinder will be larger. This will not only cause the cylinder to stick, but also the texture of the produced toilet paper will be too coarse and the spacing will become larger, and the appearance and feel will be inferior. If the wedge angle is too small, it is not conducive to wrinkling.

(3) The contact surface between the blade and the drying cylinder: The choice of the contact surface is closely related to the paper peeling point, which affects the fullness and surface texture of the paper, and also affects the surface of the drying cylinder.

At present, the materials commonly used for creping blades are mainly steel, alloy and ceramic. If the system is stable and there is no production change, ceramic doctor blades can be used. If the long fiber ratio is too high and the pulping is serious, steel doctor blades are more suitable. Alloy material can be used as a compromise between the two.
