Find here the professional airlaid paper factory and trusted airlaid paper manufacturer show you the processing techniques for airlaid paper.
Airlaid paper is a type of airlaid pulp nonwovens. From its name, we can see the two main characteristics of dust-free paper: first, the raw material is wood pulp fiber; second, it uses air-laid technology. The production process of nonwoven fabrics mainly consists of two processes: web forming and reinforcement. What are Processing Techniques for Airlaid Paper? Airlaid papermaking nonwovens mainly use two methods: chemical bonding and thermal bonding.
1.Chemical bonding method
The chemical bonding method uses wood pulp fibers (fuzz pulp) as raw materials. After the fibers are opened into a single fiber state and air-laid, a water-soluble adhesive is sprayed onto the surface of the fiber web by spraying, and then baked and reinforced into a cloth. . The main uses of the products are industrial wipes, women's hygiene products, baby wipes, tablecloths, wet facial wipes and cooking cloths.
2. Thermal bonding method
The thermal bonding method is to mix hot-melt fibers into fluff pulp fibers. The mixing ratio is generally not less than 15%. After air-laying, the low-melting fibers in the fiber web are melted by hot air or hot rolling to reinforce the fiber web into cloth. . Because the thermally bonded nonwoven fabric does not contain chemical adhesives, the product has better fluffiness and hygroscopicity. It is mainly used as the absorbent core of high-absorbent sanitary products, thin women's sanitary napkins, etc. Based on this use, some production lines are equipped with an application device for super absorbent resin (SAP) powder. Due to the addition of polymer water-absorbing resin, it can turn water into solid matter after absorbing water, greatly improving its water-absorbing capacity.
To sum up, although dust-free paper is called paper, it is essentially non-woven fabric.
1. Packed: made into sheets and packed into bags according to a certain number, specifications: 4″*4″, 6″*6″, 9″*9″, etc.
2. Roll paper shape: used for manual or automatic wiping.
Dust-free paper applications:
Semiconductor production line, microelectronics production, LCD display, LCD display, circuit board production, PCB products, laboratory dust-free workshop production line.
Features: 1. As a universal wiper made of various wet liquids for daily cleaning. 2. High humidity in both dry and wet conditions. 3. Anti-acid and resistant to most chemical reagents. 4. Low dust and anti-static, which can effectively control the amount of static electricity generated. 5. Can be used multiple times. 6. Economical and clean. It is the most widely used wipe in the electronics industry.
