Process for producing high-molecular water-absorbent resin dust-free paper

Abstract

The invention belongs to the papermaking technical field, more specifically relates to a process for producing the high-molecular water-absorbent resin dust-free paper. The process for producing the high-molecular water-absorbent resin dust-free paper takes fluff pulp wood pulp fiber, hot melt composite fiber and high-molecular water-absorbent resin (SAP) as the raw materials and the dust-free paper is composed of three-layer mixing layers. The process for producing high-molecular water-absorbent resin dust-free paper comprises the following steps: mixing the raw materials through a molding case, penetrating through hot air, wherein a heat bonding point between the hot melt fiber and wood pulp fiber formed by surface melting and flowing which are generated by the hot melt fiber during the heating process has the heat bonding effect, spraying latex on the double faces of the paper web and then drying by hot-air in a drying cylinder, rewinding to obtain the finished product. The present invention has the beneficial effects that the dust-free paper has good penetration performance and imbibition capability, is capable of effectively holding liquid, minimizing the reverse osmosis of liquid and maintaining the dry surface of the product, and has less dust and high tensile strength.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a production process of high molecular water-absorbing resin dust-free paper. Background technique [0002] In the prior art, the traditional papermaking method generally uses water as the medium, dilutes the wood pulp raw material and takes it to be formed on the net, and becomes paper after being dried. Traditional papermaking methods include the original artificial papermaking and modern mechanical papermaking. In the production process, various additives, such as bleaching agents, etc. are added to the wood pulp raw materials, and a large amount of water is used as the medium to dilute the wood pulp raw materials into a paste , and there is almost no water in the finished product, a large amount of medium water and chemical additives are filtered and discharged, resulting in waste of water resources and damage to the environment. Airlaid Paper, that is, air-l...

Problems solved by technology

[0003] The dust-free paper containing polymer water-absorbing resin is processed by thermal legal process, that is, fluff pulp wood pulp fiber, hot-melt composite fiber and polymer water-absorbing resin are mixed together. The disadvantages are: first, there is more dust. It will endanger the health of operators, and at the same time, it will have a certain impact on the normal operation of machinery and equipment, increasing the time for downtime cleaning and maintenance

Secondly, in order to maintain the high speed of the customer's equipment and maintain the bulkiness of the product, the dust-free paper of the heat-sealing process needs to add more fiber, so that the network structure in the product is tighter, which affects the absorption performance of sanitary products.
