Embodiment 1

[0022] The technical scheme adopted in the present invention is as follows: a kind of production method of the ultra-soft paper face towel of high quantitative, comprises following process according to production process:

[0023] 1) Pulping:

[0024] Coniferous wood: broad-leaved wood = 30%: 70%, the degree of percussion of coniferous wood after pulping is 22-25 0 Sr. The broad-leaved wood does not need to be pulped, and medium-concentrated pulping is sufficient. 16-18Kg of softener is added per ton of pulp, and the softener is an imidazoline compound.

[0025] 2) Sizing:

[0026] The equipment needed for the sizing process includes: the paper machine of the crescent former and the feed pump, etc.

[0027] The paper machine adopts a crescent shaper and adopts a stepped diffusion method. The pulp is divided into two layers to ensure the hand feeling and toughness. Add a wet strength agent to the inlet of the feeding pump, the wet strength agent is polyacrylamide, and the a...

Embodiment 2

[0036] The technical scheme adopted in the present invention is as follows: a kind of production method of the ultra-soft paper face towel of high quantitative, comprises following process according to production process:

[0037] 1) Pulping:

[0038] Coniferous wood: broad-leaved wood = 32%: 68%, the degree of percussion of coniferous wood after pulping is 22-25 0 Sr. Broad-leaved wood does not need to be pulped, and medium-concentrated pulping is sufficient. When pulping, 14-16 kg of softening agent is added per ton of slurry, and the softening agent is an imidazoline compound.

[0039] 2) Sizing:

[0040] Using a crescent shaper, stepped diffusion, the slurry is divided into two layers to ensure the feel and toughness. Add a wet strength agent to the inlet of the feeding pump, the wet strength agent is polyacrylamide, and the amount added is 8-13kg / ton of paper. The pulp-net speed ratio is 0.92-0.95.

[0041] 3) Dehydration & Drying:

[0042] The wet paper sheet is d...

Abstract

The invention discloses a method for producing highly quantitative soft facial tissues. The production process comprises the following steps: (1) pulping, wherein a ratio of needlebush to broadleaf wood is (20-40 percent):(60-80 percent), the beating degree of the pulped needlebush is 22-300 SR, the broadleaf wood is not pulped, intermediate concentration repulping is adopted, and 10-25kg of softening agents are added into the pulp per ton during repulping; (2) sizing; (3) dehydrating and drying; (4) wrinkling and coiling; and (5) slitting and packing. By virtue of the technical scheme, the highly quantitative soft facial tissue has a super-soft feeling and is highly quantitative, high tension stress can be kept on the basis of super-softening, and the toughness and absorption property of the facial tissues are kept.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to the technical field of household paper production. Background technique [0002] With the improvement of people's living standards, the requirements for paper facial tissues used in daily life are getting higher and higher, especially for delicate skins such as babies, children, and women. In the process of use, it is hoped to have a thick hand feeling and at the same time have a super soft, comfortable and soft feeling. The patent CN101492896A disclosed on July 29, 2009 discloses a production method of soft paper face towels, but in this method, it is produced without adding softener. For high-quantity household paper, the softness is very difficult. elevated. Contents of the invention [0003] The object of the present invention is to provide a kind of production method of ultra-soft high weight paper face towel. [0004] The technical scheme that the present invention...
