Problems solved by technology

The processing technology of this product is complicated, the production capacity is low, and the cost is also increased, and the core material formed by the paper sheet after hot pressing is poor in bulk, which affects the effect of the drug and the water-absorbing agent, and is uncomfortable to use
The core material made by hot pressing is also easy to be layered and deformed during use

Embodiment 1

[0016] Using ordinary air-laid paper production equipment with two formers, the specified amount of traditional Chinese medicine powder or granules and water-absorbing agent are sent into the two formers by means of pipeline air delivery, and after being evenly mixed with wood pulp fibers and thermally bonded chemical fibers, Air-laid technology is used to form a mesh paper sheet, which is heated and compounded by oven hot air to form a dry-laid paper core material. Chinese medicine powder or granules are evenly distributed in the entire core material. The core material thickness is 1-1.5mm and the surface density is 120g / m. 2 , the content of traditional Chinese medicine is 10%-20%, and it is cut into strips of 3-10cm according to different purposes.

Embodiment 2

[0018] Ordinary dry-laid paper production equipment with three formers is used, and the specified amount of traditional Chinese medicine powder or granules and water-absorbing agent are sent to the middle former by means of pipeline air delivery, and are evenly mixed with wood pulp fibers and thermally bonded chemical fibers, and airflow is formed. Net, hot air heating composite process is as embodiment 1. The core material of dry-laid paper formed is a whole of three layers, and Chinese medicine powder or granules are evenly distributed in the middle layer, the thickness of the core material is 1.5-2.5mm, and the surface density is 140g / m 2 , the addition of traditional Chinese medicine is 15% to 30% of the weight of the core material, and cut into strips with a width of 3.8 to 12 cm according to the application.

Embodiment 3

[0020] Using ordinary dry-laid paper production equipment with two formers, the prescribed amount of traditional Chinese medicine powder or granules and water-absorbing agent are sucked into one of the formers by means of negative pressure, mixed evenly with wood pulp fibers and thermally bonded chemical fibers, and air-laid , The composite process of hot air heating is as in embodiment 1. The formed dry-laid paper core material is a whole of upper and lower layers, and traditional Chinese medicine powder or granules are evenly distributed in one layer. The thickness of the core material is 2.5~4mm, and the surface density is 270g / m 2 , the content of traditional Chinese medicine is 10% to 30%, and it is cut into strips with a width of 4 to 12 cm according to different purposes.

Abstract

The invention discloses a liquid-absorbing core material of traditional Chinese medicine health-care dry-laid paper for sanitary napkins in the field of air-laid paper production and a manufacturing method thereof, which is composed of wood pulp fibers and thermally bonded chemical fibers. Chinese medicine powder or granules and water-absorbing agent are evenly distributed in the whole core material, or evenly distributed in the part of the core material; latex is applied on the surface of the core material; Chinese medicine is Artemisia argyi, Mint, Angelica, Motherwort, Houttuynia cordata, Rhizoma Cyperi, and Baibu. The production method adopts the traditional dry-laid paper production process and air-laid technology. The powder or particles of traditional Chinese medicine and the water-absorbing agent are sent into all or one of the formers by pipeline air delivery or negative pressure suction, and all or part of the core material is made after mixing. Products that evenly contain Chinese medicine powder or granules; or use mechanical vibration to sprinkle Chinese medicine powder or granules on a layer of fiber net, and use suction to suck the Chinese medicine powder or granules into this layer of fiber net, and heat it with another layer of fiber net complex. The advantage is that the traditional Chinese medicine is evenly distributed, the core material is soft and fluffy, not layered, and the use effect is good.

Description

technical field [0001] The invention relates to the technical field of air-laid paper production, in particular to a method for manufacturing a liquid-absorbing core material of traditional Chinese medicine health-care dry-laid paper for sanitary napkins. Background technique [0002] With the continuous improvement of people's living standards, people's awareness of health care is increasing. At present, traditional Chinese medicine health care sanitary napkins are deeply favored by women at home and abroad. [0003] The core material used in ordinary sanitary napkins in the market today is only composed of ordinary wood pulp and heat-bonded chemical fiber plus a certain amount of polymer water-absorbing agent, and its function is simply to absorb liquid. [0004] The existing traditional Chinese medicine health care sanitary napkin core material on the market is just spreading some Chinese medicine powder on the sanitary napkin core material, or making a slurry of Chinese...
