Get into care business with air-through-bonding
Innovative solutions for various products of the growing hygiene market - with ANDRITZ neXline air-through bonding eXcelle and neXline air-through bonding aXcess
In daily life, we find products using air-through bonding technology everywhere we look. The hygiene market requires products with a high level of uniformity, softness, bulkiness, and tensile strength. Due to population growth and aging as well as the rise in the standard of living, these products respond perfectly to the quality level requested for baby diapers, feminine hygiene or adult incontinence.
ANDRITZ offers tailored made air-through bonding with eXcelle lines for high capacities and aXcess lines for small and medium capacities.
ANDRITZ offers you customized solutions: For the production of hygiene products, we can deliver a tailor-made, Air-Through-Bonding (ATB) process. It makes use of the vast expertise that ANDRITZ has to offer in a wide range of hygiene nonwovens technologies, such as web forming and finishing (spunlace, spunlaid, spunjet, wetlace), and converting (baby diapers, feminine hygiene, adult incontinence).

Opening & Blending for Air-through-bonding
It all starts with fibers: To spread them evenly on the way to the web former, you need a carefully designed process. With opening, blending (APC), feeding and carding technology from ANDRITZ, your nonwovens benefit in every step.
Complete range of cards for Air-through-bonding
ANDRITZ has the matching card for you: With carding power
alternatives (single or double card set-up), different web structure
solutions, and different number of doffers, we always find the
State-of-the-art in bonding for Air-through-bonding
The oven is a very important machine in the ATB process: It must bind the still fragile and sensitive carded web smoothly into a stable nonwoven product – without reducing its high-lofted character and superior softness.
Once in the oven, the hot air
activates the low-melt polymer
inside the fiber matrix. It flows
towards and gathers at the point of fiber contacts, where these accumulations then form the bonds between the individual fibers.
Two highly sophisticated oven systems
The fragile structure of the unbonded nonwoven web calls for a suitable transport medium: this can be either a flat oven system using an air-permeable conveyor belt or an Omega oven system with a perforated and / or sievefabric covered drum surface. ANDRITZ’s portfolio can offer you the flat as well as the Omega design, both as best suitable for covering all your requirements as a hygiene nonwoven producer. Depending on your demand, the ovens can be equipped with either indirect heating (electrical power, thermal oil) or direct heating (natural or liquid gas). A common feature of the flat and Omega designs is the one-sided, airthrough ventilation, which is typical of air-through bonding processes in the hygiene market.
The new ANDRITZ SoftJet air guidance offers you an additional advantage in flat oven systems. Even the most sensitive fiber blends and matrix structures retain their high-lofted character and superior softness after the air-through bonding process.
