Example Embodiment

[0026] Example one

[0027] (1) Pulp:

[0028] Intermittently pulverize 2.3kg of natural bamboo pulp with a hydraulic pulper. The percussion degree of the natural bamboo pulp is 12°SR, the brightness is 38.3, and the wet weight is 10g / m. 2 ;

[0029] At the same time, 2.5kg solid caustic soda, 0.8kg beating enzyme and 1.1kg CMC enhancer are added to the pulper per ton of natural bamboo pulp.

[0030] The pulp concentration is 9.3wt.%;

[0031] (2) Refining:

[0032] Refining in series with disc running-in cone mill, adding resin control agent to the outlet of the refining, the refining flow is 46m 3 / h, the added amount of the resin control agent is 15mL / min,

[0033] The concentration of refining is 4.8wt.%, and the degree of tapping after refining is 24.5°SR,

[0034] (3) Copymaking:

[0035] The pulp-to-net speed ratio is 1:1.02. Wet strength agent and paper dispersant are added in the papermaking process. The amount of paper dispersant polyoxyethylene is 0.5kg / ton of bamboo pulp. The te...

Abstract

The invention relates to natural-color bamboo pulp kitchen paper and a preparation method thereof. The preparation method of the natural-color bamboo pulp kitchen paper is as follows: the natural-color bamboo pulp kitchen paper is prepared from raw material fiber by crushing into pulp, grinding pulp, and papermaking. Various performances of the natural-color bamboo pulp kitchen paper are greatly improved compared with commercially available kitchen paper: and the longitudinal tension is increased by about 30%, the wet strength is improved by more than once, the stiffness is improved by 15-20%,and the natural-color bamboo pulp kitchen paper is high in oil absorption rate, is quite suitable for wiping oil stains in a kitchen and is not easy to tear.

Description

technical field [0001] The invention belongs to the field of papermaking, and in particular relates to natural-color bamboo pulp kitchen paper and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the use of paper towels is becoming wider and wider, and there are more and more types of paper towels. Kitchen paper towels are also becoming more common because of their quick and easy decontamination and easy disposal. But in the prior art, since kitchen stains are mainly oily stains, general kitchen paper towels are not ideal for cleaning oily stains. Of course, wet paper towels are also used for decontamination, but wet paper towels are made of a mixture of base material and emulsion , high cost and higher processing cost. Contents of the invention [0003] In order to solve the above problems, the present invention provides a natural color bamboo pulp kitchen paper with good degreasing effect and a preparation m...
