ATIRA is a non-profit textile institute established in 1949 in Ahmedabad, India to help the textile industry become more competitive internationally. It has recently been designated a "Centre of Excellence" in composites. The ATIRA Incubation Centre contains the latest machinery from Germany and Switzerland for non-woven technologies, allowing small businesses access to technologies they could not otherwise afford. The Centre provides coating and lamination services using a multi-roller machine that applies hot melt adhesives in an environmentally friendly way. Coating and lamination can improve the strength and properties of non-wovens for various applications such as packaging, medical supplies, and more.

2. About ATIRA…
ATIRA – first premier non-profit Textile Institute of the country set up
way back in 1949.
ATIRA was especially established to with objective to motivate textile
& allied industries to become internationally competitive. ATIRA has
been now designated as “Centre of Excellence” in Composites by
the Govt. of India.

3. Machineries those are installed at the Incubation Centre, ATIRA are
imported from Germany and Switzerland. Most of the machinery
installed is one of its kinds in India. It’s not possible for every small
or medium scale industry or entrepreneur to have an exposure to
the latest and the best technology.
At the Incubation Centre all latest technologies have come under
one roof. So that one could visit and see the machineries in
operation, have technical discussion and take trials if wishes to.

5. Nonwovens are as sheets or web structures bonded together by
entanglement of fibers or filaments.
Mechanical Manufacturing-
by interlocking felts with serrated needles such that the inter-fiber
friction results in strong fabric
Thermal Manufacturing-
applying and melting binder onto web by increasing temperature
Nonwovens

6. Why Nonwovens ?
Nonwovens are not made by knitting or weaving and do not require
converting fibers to yarn
Certain percentage of recycled fabrics can be used while
manufacturing nonwovens resulting more economical compared to
woven fabrics.
Strength of nonwoven fabric depends on the percentage of the
recycled fabric incorporated while manufacturing

7. Post-processing on Nonwovens
In many of the applications, nonwovens as such can not be used.
Lacks in Strength and required environmental conditions.
Need some further treatment depending on final applications,
Coating on Nonwovens-for packaging, medical, etc…
Lamination on Nonwovens-for filters, insulations, etc…

8. Coating & Lamination
Incubation Centre at
ATIRA is equipped with
LACOM KIENER,
Germany Multi-roller
coating and Lamination
machine to serve
nonwoven industries.

9. Machine Specs

combustion installations)
Low Energy Consumption (no energy required for curing/drying)
PSA and Heat-activated systems available
High Speed adhesive application possible
High moisture and water resistance
Rapid further processing
Permanent / Nonpermanent adhesive coating

11. Features:
Good Peel Strength
Waterproof / Water resistivity *
Breathable *
Soft & many more
* as per requirement of the
application
Why Coating on Nonwovens ?

12. Hotmelt Dot / Gravure
Lamination
Any design can be achieved
Suitable for Garmenting
Application of low GSM

13. Ultrasonic welding is also possible on hot-melt coated nonwovens as
the ultrasonic frequency (20 & 35 kHz) with amplitude (10 µm to 50 µm)
activates the molecules of the hot-melt adhesives to perform binding /
welding

14. Water-Proofness Coating on
Nonwovens for medical such as
apparels, medical tapes…

15. Various Metalized BOPP Film
lamination on Nonwoven fabrics
for packaging, garmenting
industries

16. Aluminum foil to Nonwoven
Lamination for Thermal Insulation
used as automobile covers,
thermal blankets in industries….
