What is the difference between dust free paper & dust-free cloth?

Let’s the expert airlaid paper maunfacturer and airlaid kitchen paper wholesaler explain the detailed differences between dust-free paper and dust-free cloth.

First, the airlaid paper is also called dust-free paper, dry papermaking non-woven fabric, is different from dust-free cloth. Dust-free cloth is an ordinary fiber. Its content is 100% single-layer polyester fiber and has ultra-fine fibers. The weight is 75% polyester and 25% nylon.

Dust-free paper technology is a type of dry-laid nonwoven fabric. Suyu dust-free paper has unique physical properties, including high elasticity, softness, excellent hand feel, and excellent drape. It has extremely high water absorption and good water retention properties. It is widely used in health care products, special medical supplies, and industry. Wiping supplies and other fields.

From its English name (Airlaid Paper), we can see the two main characteristics of dust-free paper:

First, the raw material is wood pulp fiber;

The second is to use air-laid technology.

The production process of nonwoven fabrics mainly consists of two processes: web forming and reinforcement. Dry papermaking nonwovens mainly use two methods: chemical bonding and thermal bonding. According to its different reinforcement processes, its raw materials and uses are different, which are introduced below.

1. Chemical bonding method The chemical bonding method uses 100% wood pulp fiber (fuzz pulp) as raw material. After the fibers are opened into single fiber state and air-laid, the water-soluble adhesive is sprayed onto the fiber mesh by spraying method. The surface is then baked and reinforced into 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 point fibers in the fiber web are melted by hot air or hot rolling. Consolidate the fiber mesh 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.

Dust-free paper is essentially different from dust-free cloth, and its uses are also very different, such as ultrasound, laser, cold cutting, etc.! Suitable for industries without semiconductors, as well as clean workshops with level 10 to 10,000 in the electronics industry, dust-free cloth must be used, and dust-free paper such as semiconductor production line chips and microprocessors comes in handy!
