Embodiment 1

[0019] Step 1, pulping the bamboo pulp of 50 parts by weight and the cotton pulp of 40 parts by weight with a hydraulic pulper, and beating to 20 ° SR and 24 ° SR respectively with a series double disc mill;

[0020] Step 2, the above-mentioned two kinds of pulp after beating are pumped to the mixing tank and fully mixed to obtain a mixed pulp, and then the mixed pulp is mixed with 20 parts by weight of wood pulp beaten to 18 ° SR in advance to obtain a total mixed pulp;

[0021] Step 3, the above-mentioned total mixed slurry is sent into the stainless steel mixing tank, and 1.5 parts by weight of PPE wet strength agent is added to the stainless steel mixing tank and stirred evenly to obtain the pulp;

[0022] Step 4: The pulp is refined and homogenized, and paper is made by an inclined-wire paper machine, then wrinkled by a wet scraper, dried in a drying cylinder, and then cut and packaged to obtain a finished medical crepe paper base paper.

Embodiment 2

[0024] Step 1, pulping the bamboo pulp of 40 parts by weight and the cotton pulp of 30 parts by weight with a hydraulic pulper, and beating to 22 ° SR and 21 ° SR respectively with double disc mills in series;

[0025] Step 2, the above-mentioned two kinds of pulp after beating are pumped to the mixing tank and fully mixed to obtain a mixed pulp, and then the mixed pulp is mixed with 15 parts by weight of wood pulp beaten to 20 ° SR in advance to obtain a total mixed pulp;

[0026] Step 3, sending the above-mentioned total mixed pulp into the stainless steel mixing tank, adding 1.0 parts by weight of PPE wet strength agent to the stainless steel mixing tank and stirring evenly to obtain the pulp;

[0027] Step 4: The pulp is refined and homogenized, and paper is made by an inclined-wire paper machine, then wrinkled by a wet scraper, dried in a drying cylinder, and then cut and packaged to obtain a finished medical crepe paper base paper.

Embodiment 3

[0029] Step 1, pulping the bamboo pulp of 30 parts by weight and the cotton pulp of 25 parts by weight with a hydraulic pulper, and beating to 19 ° SR and 23 ° SR respectively with a series double disc mill;

[0030] Step 2, the above-mentioned two kinds of pulp after beating are pumped to the mixing tank and fully mixed to obtain a mixed pulp, and then the mixed pulp is mixed with 25 parts by weight of wood pulp beaten to 22 ° SR in advance to obtain a total mixed pulp;

[0031] Step 3, sending the above-mentioned total mixed slurry into the stainless steel mixing tank, adding 0.8 parts by weight of PPE wet strength agent to the stainless steel mixing tank and stirring evenly to obtain the pulp;

[0032] Step 4: The pulp is refined and homogenized, and paper is made by an inclined-wire paper machine, then wrinkled by a wet scraper, dried in a drying cylinder, and then cut and packaged to obtain a finished medical crepe paper base paper.

Abstract

The invention relates to the field of papermaking and provides medical crepe paper raw paper which has strong air permeability, high strength, high elongation, good antibacterial effect and low consumption of wood fibers, and a manufacturing method thereof. The medical crepe paper raw paper is prepared from following fiber raw materials in parts by weight: 30-50 parts of bamboo pulp, 25-40 parts of cotton pulp and 15-30 parts of wood pulp. The medical crepe paper raw paper is prepared from the above fiber raw materials in proportion by a traditional process comprising the steps of pulping, beating, grinding, homogenizing, papermaking, creping and drying.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a base paper for medical crepe paper and a manufacturing method thereof. Background technique [0002] At present, the paper industry occupies a certain position in the national economy and is one of the important symbols to measure the level of modernization and civilization. Medical crepe wrapping paper can bend steam and other media into the packaging, effectively kill bacteria and other microorganisms and effectively block microorganisms, and can ensure that the sterilized sterile instruments are delivered in a sterile state or stored for a long time without Infected. The medical crepe paper currently on the market usually uses wood pulp as the main component. The medical crepe paper made of it generally has disadvantages such as poor air permeability, low strength, poor elongation, and poor antibacterial effect. At the same time, it consumes too much wood fiber. Contents of...
