Problems solved by technology

[0002] At present, most of the toilet paper on the market is white. In order to make the paper "high white" and "soft" during the production process, manufacturers usually add various chemical additives such as talcum powder and fluorescent whitening agent. Toilet paper containing excessive amounts of fluorescent bleach may also cause cancer
At the same time, the raw materials used in toilet paper are usually bleached chemical wood pulp, which contains chlorides, which are also potentially harmful to human health.

Embodiment 1

[0013] refer to figure 1 , a kind of whole wood pulp natural color ecological environmental protection toilet paper production process, comprises the following steps:

[0014] (1) Use uncolored wood pulp boards with a mass fraction of 100% to decompose with a hydraulic pulper at a temperature of 40°C-50°C for 1.5 hours, control the mass concentration of the pulp to 4-5%, and then pump it to the pre-knock pool;

[0015] (2) Add edible yeast accounting for 0.1% of the weight of the natural color wood pulp board to the knocking pool, and ferment for 4-6 hours at 28-30°C;

[0016] (3) The fermented pulp is beaten by 4 sets of 450 disc mills, and then pumped to the forecourt;

[0017] The specific beating process is as follows:

[0018] Beating concentration: 3.8-4.0%

[0019] Percussion degree 42-45°SR

[0020] Wet weight 4-5g.

[0021] (4) The finished beating pulp is pumped to the high-level box, sent to the wire section for forming, and the concentration of the net is cont...

Abstract

The invention relates to the technical field of papermaking technologies, and concretely relates to a production technology of all-wood-pulp unbleached ecological environmentally-friendly toilet paper. The technology concretely comprises the following steps: 1, defibering 100% by mass of unbleached wood pulp plates with a waterpower pulper, adding edible yeasts having a weight being 0.1% of the weight of the resulting unbleached wood pulp, and fermenting at 28-30DEG C for 4-6h; 2, beating the fermented pulp with a millstone mill, wherein beating parameters comprise that the beating concentration is 3.8-4.0%, the beating degree is 42-45DEG SR, and the wet weight is 4-5g; and 3, sequentially carrying out operations of wet end shaping, squeezing dehydration, drying, reeling, rewinding and slitting on the beaten pulp to obtain the toilet paper. The technology of the invention has the advantages of simplicity, convenient operation, and no bleaching in the product production process, no addition of any chemical additives; and the toilet paper of the invention has the characteristics of softness, fineness, durability, and radiation of a natural fiber fragrance, and can reach requirements of food level paper for daily life.

Description

technical field [0001] The invention relates to the technical field of papermaking technology, in particular to a production process for whole wood pulp natural color ecological environment-friendly toilet paper. Background technique [0002] At present, most of the toilet paper on the market is white. In order to make the paper "high white" and "soft" during the production process, manufacturers usually add various chemical additives such as talcum powder and fluorescent whitening agent. Toilet paper that contains excessive amounts of fluorescent bleach may also cause cancer. At the same time, the raw material used in toilet paper is usually bleached chemical wood pulp, which contains chlorides, which is also potentially harmful to human health. Contents of the invention [0003] The present invention aims at the disadvantage that the existing bleached toilet paper is harmful to the body after long-term use, and provides a production process of whole wood pulp natural co...
