Embodiment 1

[0037] The hydrophobic modification of embodiment 1 kenaf core

[0038] Kenaf core has a well-developed microcavity structure, the main chemical components are cellulose, hemicellulose and lignin, and has good oil adsorption potential. Simultaneously absorb oil and water. In this embodiment, the kenaf core is hydrophobically modified to improve the oil adsorption performance of the kenaf core.

[0039] Specific steps are as follows:

[0040] 1. Preparation of kenaf core granules:

[0041] Utilize pulverizer to pulverize commercially available kenaf core, and sieve to obtain 80-100 mesh kenaf core particles;

[0042] 2. Pretreatment of kenaf core particles

[0043] Mix the crushed and sieved kenaf core particles with 40g / L NaOH solution, the mass ratio of the NaOH solution to the kenaf core particles is 15:1, shake at a constant temperature at 40°C for 6h, and then neutralize it to pH with hydrochloric acid =7, after suction filtration, washing and drying, ball milling for...

Embodiment 2

[0046] Embodiment 2 comprises the preparation of the paper of modified kenaf core

[0047] The modified kenaf has good adsorption performance for oil stains. In this example, the paper with good oil stain adsorption performance is prepared by adding modified kenaf particles to paper.

[0048] Specific steps are as follows:

[0049] (1) 20 parts of coniferous fiber, 35 parts of bamboo fiber, and 25 parts of bagasse fiber are crushed into wood pulp through a pulper, and the slag is removed through a high-concentration slag removal system, and impurities are removed by a coarse sieve. Sieve and concentrate to obtain fiber wood pulp;

[0050] (2) Put the fiber wood pulp in the pulper, add water to adjust the wood pulp concentration to be 6.0wt%, and after 10 minutes of disintegration, the resulting pulped material will be disentangled by the fiber disintegration machine, and then beaten by a beater to obtain Fiber wood pulp after tapping, the beating degree is 32°SR;

[0051] (...

Embodiment 3

[0054] Embodiment 3: the influence of the addition amount of kenaf core on paper oil-absorbing performance

[0055] In order to explore the impact of the addition of different kenaf cores on the oil-absorbing performance of paper, and strive to find the most suitable addition of kenaf cores, the present embodiment adopts the following experimental design:

[0056] In the preparation of paper, the addition amount of different kenaf core mixtures is adopted, and the specific addition amount of kenaf core mixture is as shown in Table 1,

[0057] The addition amount of kenaf core compound in table 1 paper

[0058]

[0059] For the above-mentioned different concentrations, three parallel experiments were set up for each group, and the specific steps were as follows:

[0060] 1. Paper Preparation

[0061] (1) 20 parts of coniferous fiber, 35 parts of bamboo fiber, and 25 parts of bagasse fiber are crushed into wood pulp through a pulper, and the slag is removed through a high-c...

Abstract

The invention provides a production method of paper towel or kitchen paper and a paper preparation method thereof. The paper is processed by primary drying, wet creping paper, secondary drying, and winding. The paper is made of 20 parts of coniferous fiber , 35 parts of bamboo fiber, 25 parts of bagasse fiber, 0.25wt% softening agent, 1.25wt% wet strength agent, 10.8wt% kenaf core mixture and 3.6% immobilized compound lipase are prepared by wet method Creping is combined with a vacuum pick-up device to crepe the paper to ensure the quality of the paper and the problem of paper dust. After adding modified kenaf core and immobilized compound lipase to paper, and finding out the best addition amount, kenaf core can improve the oil absorption performance of paper, and can further ensure wet wrinkling and vacuum The operation of picking up paper ensures the quality of the finished paper.

Description

technical field [0001] The invention relates to the technical field of paper production, in particular to a paper with grease degradation ability and a preparation method thereof. Background technique [0002] With the rapid development of the economy and the improvement of living standards, people's demand for disposable kitchen paper is increasing, because it is more hygienic and convenient than traditional dish towels and rags, but there are many disposable rags on the market. Polyester fiber is used as a raw material through spunlace composite technology. Due to the high cost of raw materials and complicated preparation process, the popularization and application of disposable rags are affected, and the paper prepared from this component has low oil absorption. . [0003] Because of the wrinkling process, wrinkled toilet paper has softness and water absorption that ordinary paper does not have. The wrinkle of wrinkled toilet paper is divided into dry method and wet met...
