Example Embodiment

[0018] Example 1:

[0019] Fiber ratio: 55% softwood, 30% cotton pulp, 15% manila hemp

[0020] Fiber treatment:

[0021] The first step: the cotton pulp and Manila hemp pulp trough-type beater is used for heavy knife decomposing, the concentration is controlled at 2.5-3.0%, the current is 30-35A, ten minutes later, it enters the high-frequency decomposer for 90 minutes, and the beating degree reaches 41 0 SR, wet weight 31.5g, drive into slurry tank for later use.

[0022] The second step: the softwood pulp is decomposed with a trough-type beater at a low concentration, the concentration is controlled at 2.0%, and the current is 30-35A. After 30 minutes, it is beaten into the pulp tank and mixed with cotton pulp and manila hemp pulp.

[0023] The third step: After the above slurry is evenly mixed, it enters the 3# tooth-shaped disc mill and 4# tooth-shaped disc mill in series to circulate treatment until the mixing beating degree is 40-45 O SR, wet weight 13.5g.

[0024] The fourth step...

[0027] Example 2:

[0028] Fiber ratio: 50% softwood, 20% hardwood, 30% cotton pulp

[0029] Fiber treatment:

[0030] The first step: the cotton pulp is decomposed in the slurry tank type beating machine with heavy knife, the concentration is controlled at 2.5-3.0%, the current is 30-35A, after ten minutes, it enters the high-frequency decomposing machine for 90 minutes, and the beating degree reaches 35 0 SR, wet weight 26g, drive into slurry tank for later use.

[0031] The second step: the softwood pulp is decomposed with a trough-type beater at a low concentration, the concentration is controlled at 2.0%, and the current is 30-35A. After 30 minutes, it is beaten into the pulp tank and mixed with cotton pulp and manila hemp pulp.

[0032] The third step: After the above slurry is evenly mixed, it enters the 3# tooth-shaped disc mill and 4# tooth-shaped disc mill in series to circulate treatment until the mixing and beating degree is 40-45 O SR, wet weight 12.5g.

[0036] Example 3:

[0037] Fiber ratio: 65% softwood, 35% manila hemp

[0038] Fiber treatment:

[0039] The first step: Manila hemp slurry tank-type beating machine heavy knife decomposing, the concentration is controlled at 2.5-3.0%, the current is 30-35A, ten minutes later, it enters the high-frequency decomposing machine for 90 minutes, and the beating degree reaches 45 0 SR, wet weight 46g, drive into the slurry tank for later use.

[0040] The second step: the softwood pulp is decomposed with a trough-type beater at a low concentration, the concentration is controlled at 2.0%, and the current is 30-35A. After 30 minutes, it is beaten into the pulp tank and mixed with cotton pulp and manila hemp pulp.

[0041] The third step: After the above slurry is evenly mixed, it enters the 3# tooth-shaped disc mill and 4# tooth-shaped disc mill in series to circulate treatment until the mixing and beating degree is 40-45 O SR, wet weight 17.5g.

Abstract

The invention discloses a production method of non heat seal teabag paper. Final products can be obtained through a surface sizing process or a coating process in the existing production method of the non heat seal teabag paper, and a plurality of adhesives and additives are needed to add. The production method includes subjecting plant fibers to special processing, and reserving the length of fibers as far as possible during fully fibrillation; and adding appropriate thermosetting type reinforcing agent into the fiber after the special processing to obtain a body paper product through papermaking. The body paper product can be used directly without the surface sizing and the follow-up coating processing and can adapt to processing requirements for modern high-speed packing machines. According to the production method, the defect that final products can be obtained through the surface sizing or coating in the existing production method of the non heat seal teabag paper is overcome, the paper is formed once, the surface sizing or coating process is reduced, usage of chemical additives in the non heat seal teabag paper is reduced, obtained products are environment-friendly and good in processability, simultaneously, the production process is simplified, and the energy consumption and cost are reduced.

Description

technical field [0001] The invention relates to a manufacturing method of a non-heat-seal tea filter paper, in particular to a non-heat-seal tea filter paper of whole plant fiber without surface sizing or coating. Background technique [0002] The traditional manufacturing method of non-heat-seal tea filter paper is that the fibers are formed by paper machine and then surface sized or coated. This type of manufacturing method has many links in the whole manufacturing process, many chemical additives, and large energy consumption. With the improvement of people's quality of life, higher requirements are put forward for the environmental protection, health and safety performance requirements of products. The main purpose of the manufacturing method is to reduce the use of chemical products as much as possible, and at the same time, since the manufacturing method does not require surface sizing or coating processes, the energy consumption is obviously reduced. Contents of th...
