Production technology and market of dust-free paper

Latest company news about Production technology and market of dust-free paper

Early dust-free paper did not undergo surface foaming treatment, resulting in serious lint and powder falling, poor production and operation environments, heat-bonded fibers weakening strength far below that of glue dust-free papers, yet demand persisted in spite of these limitations.

Therefore, to take into account both advantages, an optimal dust-free paper product was developed:


1. Method for Bonding Dust-free Paper

Hot-melt fiber bonding and latex surface bonding are used for dust-free paper production, with latex fiber being used as raw materials while hot-melt fiber being added as needed to further increase liquid absorption performance. SAP can be added for improved liquid absorption performance; bulkiness, softness, dry/wet strength performance as well as appearance performance such as lint loss are among its poorer characteristics.


2. Chemical Bonding Method

Chemical bonding techniques utilize 100% wood pulp fiber (fluff pulp) as raw material, air-laid into single fiber states by air laying, then coated with water-soluble adhesive using spraying technology before being baked to strengthen into cloth fabric for use in products like industrial wipes, feminine hygiene products, baby wipes, tablecloths, wet wipes and cooking cloths, etc.

3. Thermal Bonding Method
This thermal bonding technique involves mixing hot-melt fibers into fluff pulp fibers at a mixing ratio not less than 15%. Once air-laid, low melting-point fibers of the web are melted by hot air or rolling to strengthen it into cloth form. Thermally bonded non-woven fabrics do not contain chemical adhesives and thus have improved bulkiness and hygroscopicity. Superabsorbent polymers (SAPs) are often used as the absorbent core of high-absorbency sanitary products and thin sanitary napkins, and for this purpose certain production lines have an application device for superabsorbent resin (SAP) powder application. With the addition of polymer water-absorbing resin, water can turn to solid after being absorbed thereby greatly increasing their water-retaining capability.

4. Low dust and anti-static capabilities can effectively limit static electricity generation;


5 can be reused multiple times;


6. Economical and clean, this paper wipe is one of the most widely utilized in electronics industry.


Air-free paper remains primarily utilized for absorbent products, including women's sanitary napkins, sanitary pads and baby diapers. However, specially-designed comprehensive dust-free papers like Kimberly-Clark's commercial and consumer division can nearly replace nonwoven fabrics in industrial uses like wet wipes or various wipes.


Current Chinese usage generally refers to heat-bonded dust-free paper and comprehensive dust-free paper as heat-bonded dust-free paper, while heat-bonded dust-free paper that has not undergone surface treatment is no longer seen as such.
