Production process of non-heat-seal type tea filter paper

Abstract

The invention discloses a production process of non-heat-seal type tea filter paper. The production process comprises the steps that S1, plant fibers soaked with sulfite are added into a beater, when the beating degree of slurry ranges from 15 SR to 25 SR, beating is stopped, an enhancer is added into the beater, slurry A is obtained, and the slurry is discharged for use; S2, a cross-linking agent and starch are added into the slurry A prepared in S1, the oven dry ratio of the cross-linking agent to the starch ranges from 1:120 to 45:120, then stirring is carried out for 25 min to 35 min, the materials are fully mixed to be uniform, and slurry B is obtained; S3, 5-6% flocculant is added into the slurry B prepared in S3, the mass concentration of paper pulp ranges from 0.14% to 0.16%, the materials are mixed and stirred to be uniform, then net feeding and paper manufacturing are carried out, press polishing and rolling are carried out through a paper maker, and the finished paper is made. The non-heat-seal type tea filter paper made through the process contains no harmful chemical additive, is environmentally friendly and practical, has wide market popularization value and can be widely applied and popularized.

Description

technical field [0001] The invention belongs to the technical field of filter paper, and more specifically relates to a non-heat-sealable tea filter paper. At the same time, the invention also relates to a production process of non-heat-sealable tea filter paper. Background technique [0002] Tea raw materials, packaging materials and teabag packaging machines are the three elements of teabag production, and packaging materials are the basic conditions for teabag production. Non-heat-sealable tea filter paper is a kind of substitute tea packaging materials. There is a heat-sealed tea filter paper. Teabags are very popular in European and American countries because of their convenient and hygienic drinking, quick dissolution of active ingredients in the tea leaves, and accurate quantification when drinking. More than 80% of the tea leaves in Canada, Italy, Holland, France and other countries are consumed in the form of teabags, and the UK and the U.S. have also reached abou...

Problems solved by technology

At present, in the production of special paper in my country, only a few factories of non-heat-sealable tea filter paper continue to use the traditional inclined wire paper machine for production, which has the disadvantages of complicated process and high consumption cost, and most of the raw materials in production are hemp pulp. Hemp pulp is more expensive

In addition, although the non-heat-sealable tea filter paper production process disclosed in the patent application with publication number CN 102002891A uses a cylinder paper machine instead of an inclined wire paper machine, it uses bleached sulfate with short fibers and poor strength. Coniferous wood chemical pulp and cotton pulp are used as raw materials, and the non-heat-sealable tea filter paper made of it has poor brewing resistance and is easy to break
