Can you achieve more by omission? McAirlaid’s answer to this question is SuperCore. Latex, adhesives or bonding agents were deliberately left out. Therefore, it can absorb significantly more fluid compared to other fleeces. This is exclusively available only at McAirlaid’s.
Pure cellulose fibres are placed on top of each other with the help of air streams. They are compacted by means of a patented production process, which works without adhesives or bonding agents
This is the decisive difference. The base of all our airlaids consists through and through of pure, highly absorbent fresh cellulose – never recycled fibres.
This is how we achieve pure absorption power without barriers adhesives etc., which often run through conventional absorbent fleeces like a network of grids. Other manufacturers use adhesives. Due to purely thermo-mechanical fibre bonding, SuperCore has pure absorption power.
In comparison to conventional absorbent cores, impressive absorption performance and optimum fluid distribution is achieved despite minimised material thickness.
Pure cellulose can absorb liquid its own weight many times over. However, sometimes even greater absorption is required. This is when we upgrade the absorption power of our products with super-absorbers. Super-absorbers can, for instance, absorb 100 times of their amount in tap water. Absorbed liquids immediately turn into gel. This is how they ensure a noticeably “dry” surface. Once locked-in, liquid is stored by SuperCore as if in a safe, even when under pressure. This makes McAirlaid’s unique in the market.
In this process, polymer granules are melted and molten polymer is extruded through spinnerets. The continuous filaments are cooled and deposited on a conveyor belt to form a uniform web. A certain residual temperature can cause filaments to adhere to each other, but this cannot be considered the most important method of joining. The spunbonded process has the advantage of giving the nonwovens a higher strength, but raw material flexibility is limited.
Conventional airlaids consist of cellulose and bonding agents. Processing does not take place as usual for the production of paper in water, but dry in a so-called compressed air procedure. Therefore the term “airlaid”. The properties of airlaid: less fluff, tear proof, extremely absorbent, kind to skin and pleasantly soft.
Wetlaid is a process whereby fibres are suspended in water to distribute them evenly. The suspension is poured onto a moving sieve that allows the water to go through, leaving a fibre fleece behind, which is dried afterwards to form the fabric.
That is the environmental footprint of our airlaid, produced free of chlorine-bleached cellulose. It is free of synthetic adhesives, latex or bonding agents, substances, which could pollute the environment.
Our production is PEFC-certified for good reason. It works with low CO2 emissions. And as no fresh water is used, there is no wastewater. Production buildings are climate controlled by means of efficient heat recovery methods. This is how we produce a good environmental conscience at all levels.
"PEFC is the largest institution for ensuring and marketing sustainable forest management through an independent certification system."
Depending on the most diverse requirement profiles, the following raw materials flow into the production process such as:
Granulates consist of dry and solid grains, which are used for example as SAP, odour binders or also as other powder substances.
Staple fibres can be used as super absorbent fibres (SAF), bi-component and monofilament fibres.
Set your imagination free – we will translate it. Two possible layer structures are shown here:
From top to bottom: PE film | SAF | Pulp | PE film
From top to bottom: Nonwoven | Cellulose | Silver ions | Cotton
The format of McAirlaid's products is also individually matched to respective further processing. You save time, wastage and costs.
