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
The present invention relates to the paper-making technology field, be specifically related to a kind of whole wood pulp true qualities ecological, environmental protective toilet paper production technology.
Background technology
At present; Toilet paper on the market is white mostly; In order to make paper reach characteristics such as " Gao Bai ", " submissive ", producer can add number of chemical auxiliary agents such as talcum powder, fluorescent whitening agent usually in the production process, but the long-term toilet paper that contains excessive optical bleaching agent that uses of human body also maybe be carcinogenic.Simultaneously, the raw material that toilet paper adopted is generally bleached wood pulp, wherein contains chloride, and health is also had potential harm.
Summary of the invention
The present invention uses insalubrious drawback to existing bleaching toilet paper is long-term, provides that a kind of technology is simple, the whole wood pulp true qualities ecological, environmental protective toilet paper production technology of ecological, environmental protective.
The concrete steps of production technology of the present invention are following:
(1) be 100% true qualities wood-pulp board after discongesting 1.5 hours with hydrabrusher under 40 ℃-50 ℃ the temperature with mass fraction; Control slurry concentration is 4-5%; Add the food yeast account for true qualities wood-pulp board weight 0.1% then, 28-30 ℃ condition bottom fermentation 4-6 hour;
(2), the slurry that ferments is pulled an oar through mill, and the following parameter of making beating control: beating consistency is 3.8-4.0%, beating degree 42-45 ° of SR, weight in wet base 4-5g;
The slurry of the making beating that (3), will accomplish successively through wet end moulding, press dewatering, drying, batch, rewinding, branch cutting process obtain finished product.
Online concentration is 1.2% in the described wet end molding procedure.
Mill in the said step (2) is 450 mills of 4 parallel connections.
Technology of the present invention is simple, easy to operate, and bleaching in the process of producing product does not have any chemical addition agent yet and adds, and product has softness, exquisiteness, durable and distribute characteristics such as fiber nature fragrance, can reach the requirement of food-grade paper for daily use.
Description of drawings
Fig. 1 is a process flow diagram of the present invention.
The specific embodiment
Embodiment 1
With reference to Fig. 1, a kind of whole wood pulp true qualities ecological, environmental protective toilet paper production technology comprises the steps:
(1) the service property (quality) mark is that 100% true qualities wood-pulp board was discongested 1.5 hours with hydrabrusher under 40 ℃-50 ℃ temperature, and control slurry mass concentration 4-5% is evacuated to then and kowtows the forebay;
(2) in kowtowing the forebay, add account for true qualities wood-pulp board weight 0.1% food yeast, 28-30 ℃ condition bottom fermentation 4-6 hour;
(3) slurry that ferments is pulled an oar through 4 450 mill, is evacuated to then and destroies the forebay;
Concrete beating process is following:
Beating consistency: 3.8-4.0%
Beating degree 42-45 ° of SR
Weight in wet base 4-5g.
The slurry of the making beating of (4) accomplishing is evacuated to header box, delivers to the wet end moulding, and control online concentration 1.2% is sent into the press section dehydration then, then through dry, batch, become paper, processing (rewinding, cut etc.) operation and obtain finished product and warehouse-in.
The product that embodiment 1 produces has softness, exquisiteness, durable and distribute characteristics such as fiber nature fragrance, can reach the requirement of food-grade paper for daily use, and it becomes paper key technical index following:
