Problems solved by technology

[0002] At present, paper is used in various fields, but the application fields of each kind of paper are very narrow, especially in the field of hygiene products, there are no papers that require high liquid absorption and liquid retention, as well as sterilization and anti-inflammatory effects. This brings certain restrictions to the application of paper.

Embodiment Construction

[0022] In order to further elaborate the high liquid-absorbent negative ion dry-laid dust-free paper and its preparation process, the following examples are used for a more detailed description:

[0023] The high liquid-absorbent negative ion dry-process dust-free paper can produce up to 4500 negative ion components per cubic centimeter of paper, and at the same time can absorb and maintain a liquid that is at most 10 times its weight. The preparation of the above-mentioned high liquid-absorbent negative ion dry-process clean paper The preparation process comprises the following steps:

[0024] 1. Select materials

[0025] High liquid-absorbent anion dry-laid dust-free paper, in which fluff wood pulp, polymer water-absorbing resin, and anion powder can be increased or decreased according to actual manufacturing purposes. The maximum addition ratio of water-absorbing resin and anion generating powder is per 1000kg of finished paper Among them, the water-absorbing resin does no...

Abstract

The invention relates to a highly-absorbent negative-iron dust-free paper made with a dry method, which is made up of 60-90 percent of anhydrous wood pulp, 5-25 percent of super absorbent polymer (SAP) and 5-15 percent of negative-iron generation powder. The highly-absorbent negative-iron dust-free paper is made with a dry method comprising the steps of dispersing the napped wood pulp, mixing loose polyethylene chemical fiber with the napped wood pulp, spraying and jetting the mixed loose polyethylene chemical fiber and the napped wood pulp on the mesh belt of a paper making machine under vacuum condition, spraying and jetting the SAP and the negative-iron generation powder through a SAP metering and adding device to shape paper, forming the paper by a reheating prepressing roll, embossing and compacting the paper, spaying gel on the paper in an atomizing way, and drying the paper with hot blast. The highly-absorbent negative-iron dust-free paper made with a dry method can improve the menstrual blood absorbing and keeping capacity by 2 to 10 times, generate 1,500 to 4,500 negative irons and play the role of highly absorbing and keeping the menstrual blood, relieving uneasiness, killing bacteria, diminishing inflammation and improving health of women, is applicable to bedridden patients for an extended time, paper diapers, wet tissues, toilet wet paper, and the like and causes no sewage or waste gas when heated by electricity or heat-conducting oil in the production process.

Description

technical field [0001] The present invention relates to a papermaking technology, in particular to a highly liquid-absorbing negative-ion dry-process dust-free paper produced by dry-process papermaking technology with high liquid absorption and liquid retention, capable of generating negative ion components while absorbing and retaining liquid, and its Preparation Process. Background technique [0002] At present, paper is used in various fields, but the application fields of each kind of paper are very narrow, especially in the field of hygiene products, there are no papers that require high liquid absorption and liquid retention, as well as sterilization and anti-inflammatory effects. This has just brought certain restriction to the application of paper. Contents of the invention [0003] The purpose of the present invention is to provide a high-intensity liquid-absorbing and liquid-retaining function that can be widely used in the field of hygiene products, and can pro...
