Problems solved by technology

Using it as crepe paper also has the following deficiencies: 1. The drying cylinder on the machine is wrinkled, the elongation of crepe paper is on the low side, the production cost is high with 100% bleached kraft softwood pulp, and the wet strength is low. It will be easy to break in the use of the subsequent process

Embodiment 1

[0024] 1. Put 90% of bleached softwood kraft pulp commercial pulp sheet and 10% hardwood pulp commercial pulp sheet in 1# hydraulic pulper for pulping treatment, and the pulp after pulping treatment is sent to 2# raw pulp pool;

[0025] 2. Then send it to the decomposing beater;

[0026] 3. Refining with a broom again, the beating degree of the pulp is 40°SR-50°SR, and the pulp is sent to the pulping tank and then added with WS-125c papermaking wet strength agent (cationic polyamide epichlorohydrin macromolecule Polymer) aqueous solution for pulping, choose WS-125c papermaking wet strength agent, its appearance is light yellow to amber viscous transparent liquid, solid content (%): 12.5±0.5%, PH value: 3-7; addition amount 6%-8% (on dry pulp), add water to dilute the measured WS-125c papermaking wet strength agent about 10 times, and add it to the pulp mixing tank.

[0027] 4. After confirming that the aqueous solution of WS-125c papermaking wet strength agent is mixed evenl...

Abstract

The invention relates to crepe paper. The paper pulp is prepared from the following raw materials: 90 percent of bleached softwood kraft pulp commercial pulp board and 10 percent of hardwood pulp. The invention further provides a process for producing the crepe paper. According to the process, 90 percent of bleached softwood kraft pulp commercial pulp board and 10 percent of hardwood pulp are mixed and subjected to fibrillation type pulping treatment, and the pulp beating degree is 45-50 degrees SR. The crepe paper produced by the process has a remarkable effect of fine and irregular crepe paper lines, has an elongation of 20-25 percent and a wet strength of 25-35 percent, and is low in production cost. According to the crepe paper, the cost can be reduced since the elongation problem of the crepe paper is greatly improved. The production process is reasonable in design and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and relates to crepe paper and a production process thereof. Background technique [0002] A crepe paper product used as a masking material in the fields of automobile manufacturing and maintenance, construction and decoration. The requirements and characteristics of crepe paper are that the surface of the paper has obvious fine and irregular lines, which greatly improves the elongation of the paper, and its elongation can reach 20%-25%. Reduced production costs. [0003] In the prior art, a kind of unbleached or 100% bleached kraft softwood pulp is used as the raw material for papermaking fiber, and a kind of papermaking fiber is made by free mode beating, pulping, papermaking on the Internet, creping and drying on the machine. The wrinkled effect of the crepe paper texture in all directions. Using it as crepe paper also has the following deficiencies: 1. The drying cylinder on the machin...
