Manufacturing method of toilet paper, manufacturing method of toilet rolls and toilet roll

Abstract

The invention provides a manufacturing method of toilet paper, a manufacturing method of toilet rolls, and a toilet roll. In the manufacturing method of toilet paper, a raw paper roll of the toilet paper is hung on an embossing roller for conveying, so that raw paper of the toilet paper passes between the embossing roller and a receiving roller and is embossed. Meanwhile, the raw paper is wound around the receiving roller and conveyed to downstream. At the same time, a spray laying device is used to apply a deodorant to a part of the embossing roller on the circumferential surface, wherein no raw paper is wound around the part. Therefore, during winding, conveying and embossing, the deodorant is trans-printed onto the raw paper. Furthermore, when the raw paper with emboss and the deodorant is wound around the receiving roller and conveyed to the downstream, or when the raw paper is separated from the receiving roller and conveyed to the downstream, the surface with the deodorant printed is stacked opposite to other raw toilet paper.

Description

technical field [0001] The present invention relates to a manufacturing method of toilet paper, roll toilet paper formed by rolling strip-shaped toilet paper around a paper tube and a manufacturing method thereof. Background technique [0002] Conventionally, it has been proposed to add a deodorant to roll toilet paper for the purpose of deodorizing the toilet space. For example, there have been proposed a method in which a deodorant is contained in a tail sealing paste for bonding toilet paper rolls, a method in which a deodorant is applied to the inner surface of a paper tube, and the like. [0003] However, in the former method, since the deodorant-applied part is used at the same time as the start of use, there is a problem in the sustainability of the deodorizing effect. In the latter method, since the position where the deodorant is applied is limited to the paper tube, there are insufficient chances of contact between the odor component and the deodorant, and further...

AI Technical Summary

Problems solved by technology

[0007] However, deodorants are effective in a small amount compared to moisturizers and are expensive, so the application amount of the agent tends to decrease, and it is difficult to manage the low application amount in this roll transfer.

In addition, deodorants may reduce the texture of paper. If the deodorant is applied to the paper surface in an amount that can be applied by roll transfer, this risk will increase.

[0008] In addition, there are substances such as organic acids in the deodorant that have an excellent deodorizing effect on the main odor components in the bathroom space such as ammonia, but such acids will rust the iron parts in the roll toilet paper manufacturing equipment

This problem can be prevented to some extent by changing the iron parts in the manufacturing equipment to stainless steel or chrome-plated parts, or by increasing the frequency of cleaning, but the cost and time are very high.

[0009] In this way, there are various problems that are difficult to solve when efficiently producing toilet paper and roll toilet paper provided with a deodorant with a high deodorizing effect.
