Embodiment 1

[0015] In this embodiment, a kind of production method of natural fruit dyed colored paper towel is taken as an example of a kind of wood pulp colored paper towel to illustrate the method of using bluegrass to prepare pure natural dyeing juice to dye and produce colored paper towel:

[0016] S1. Preparation of natural dyeing paste: indigo → washing → impurity removal → crushing → soaking → filtration and purification of dyed juice → concentration or pulping → refining to obtain natural dyeing paste (indigo).

[0017] S2. Pulping: wood → log storage → sawing → peeling and knotting → chipping → cooking → washing → screening, purification → impregnation and refining → pulp board.

[0018] S3. Preparation of paper material: loose pulp from the pulp board → beating → adding glue and filling → paper material.

[0019] S4. Mixing of natural dyeing paste and paper stock: mix the natural dyeing paste prepared in step S1 with the paper stock prepared in step S3 in a certain proportion (...

Embodiment 2

[0023] In this embodiment, a kind of production method of natural fruit dyed colored paper towels is taken as an example of a kind of bamboo pulp colored paper towels to illustrate the method of using ginger gold to prepare pure natural dye juice to dye and produce colored paper towels:

[0024] S1. Preparation of natural dyeing juice: Ginger gold→washing→removing impurities→breaking up→soaking→filtering and purifying the dyed juice→concentrating or making pulp into sheets→refining to obtain natural dyeing juice (yellow).

[0025] S2. Pulping: bamboo material → log storage → bamboo sawing → peeling and knotting → chipping → cooking → washing → screening, purification → impregnation and refining → pulp board.

[0026] S3. Preparation of paper material: loose pulp from the pulp board → beating → adding glue and filling → paper material.

[0027] S4. Mixing of natural dyeing paste and paper stock: mix the natural dyeing paste prepared in step S1 with the paper stock prepared in s...

Embodiment 3

[0031] This embodiment This embodiment presents a method for producing colored paper towels dyed with natural fruits. Taking a kind of wood pulp colored paper towels as an example, the method for dyeing and producing colored paper towels by using safflower and weed grass to prepare pure natural dyeing juice is illustrated:

[0032] S1. Preparation of natural dyeing juice: safflower→washing→removing impurities→breaking→soaking→filtering and purifying the dyed juice→concentrating or copying into pulp sheets→refining to obtain natural dyeing juice a (red);

[0033] Weed grass→washing→impurity removal→breaking→soaking→filtering and purifying the dyed juice→concentrating or copying into pulp→refining to obtain natural dyeing juice b (yellow);

[0034] Natural dyeing paste a and natural dyeing paste b are mixed to obtain natural dyeing paste c (orange red);

[0035] S2. Pulping: wood → log storage → sawing → peeling and knotting → chipping → cooking → washing → screening, purificati...

Abstract

The invention discloses a production method for a natural fruit dyed colored paper towel and belongs to the fields of pulping and papermaking. The production method comprises the following steps: S1, preparing natural dyeing juice color paste; S2, pulping; S3, blending a paper material; S4, mixing the natural dyeing juice color paste with the paper material; S5, making paper. The production method disclosed by the invention is novel and ingenious and does not need new equipment, low carbon and environment friendliness are realized in production process; the natural dyeing juice is made of a pure natural material and reaches drinking standards of food-grade fruits and vegetables; environmental pollution and harm to a human body caused by bleaching effluent, a fluorescent agent and chemical pigment are reduced; the paper towel produced with the method disclosed by the invention is abundant in colors, natural, friendly to the skin, green and healthy.

Description

technical field [0001] The invention relates to the field of pulping and papermaking, in particular to a production method for natural fruit-dyed colored paper towels. Background technique [0002] Most of the traditional paper towels are white, slightly monotonous, and not rich enough in color. More importantly, producers will add bleach and fluorescent agents during the production process, which are irritating to the eyes and skin, and are not conducive to protecting the eyesight of users. It may contain cancer-causing chemicals, induce hemorrhoids and other skin diseases, and bleach wastewater is polluting the environment. Although the original color sanitary base paper has no bleaching agent residue, its color shade is too poor, and users feel that the product is low-grade. Although the existing colored paper towels in the market are rich in color of white paper towels, most of the dyes used in these colored paper towels are basic dyes or acidic Chemical dyes such as dy...
