Airlaid Pilot Plant
Based on the newest generation Dan-Web airlaid pilot
plant machine, with two independently fed forming heads, this R&D system
offers maximum grade flexibility. Operating at relatively slow speeds compared
to commercial production lines, this pilot plant can make novel structures
for tomorrow's products today. The plant can make unusually light or
very heavy composite fabrics including those normally made on carding
equipment. 100% synthetic fiber webs are possible at both high and low
basis weights in uniformly blended composites or as layered
webs.
Marketing Technology Service, Inc. is pleased to offer
the industry a complete pilot plant airlaid former, available at our testing
facilities. The plant includes a dual-head Dan-Web air forming
machine, three synthetic fiber feeders, two pulp hammermills, an oversized
AIRTHERM through-dryer and four-roll heated calendar and offers:
- Production of 0.25 m wide webs at basis weights
from about 12 to over 1500+

- Handling of various virgin and recycled wood pulp
fibers and all kinds of synthetics up to about 14 mm depending on the
fiber used
- Production of fiber/superabsorbent composite webs -
latex, thermal or multi-bonded
This pilot facility is designed to make nonwoven,
paper, paperboard, and exotic prototype blend test rolls for confidential
client research. Additional equipment and client-supplied components
can be added to this layout on a contract basis.
MTS Airlaid Pilot Plant - General
Specification
The airlaid process for making wood pulp fibers into
roll goods has great potential. Besides obvious environmental
benefits, airlaid composite webs offer almost unlimited product development
opportunities for both the paper and nonwovens industries.
Because MTS's laboratories have many years of
experience with airlaid grade development and product testing, the new pilot
line has been specially designed to offer maximum flexibility regarding
recipes and basis weight. Designed from the beginning as a "test
roll" development facility, a great deal of prototyping can be
performed without the expense associated with running full-scale machines
for concept testing. A full range of virgin and recycled fibers,
particles and additives can be produced at ultrahigh or ultralow densities
using latex, thermal bonding or water/pressure bonding techniques.
Basis Weight
- One layer basis weight (wood pulp only measured
with no latex or SAP) is 12 - 700 g/m2. Fabrics
containing SAP can achieve much higher single-pass basis weights
- Two separate forming heads are available with fully
independent pulp and synthetic fiber feeds, allowing complex multi-layer
or homogenous webs
- Multipass is also possible to build even more
exotic layered fabrics and for high basis weights
Density
- 0.03 to about 0.3g/cm3
- Compression rolls both before and after the dryer
allow production of high bulk tissue-type webs or high density
paperboard
Superabsorbent Addition
- Homogeneous blends, tight center web SAP layers or
center layer SAP mixed with fiber
- Controllable layers with SAP injected in the center
and fiber veneers on the outside
- 0 - 90% granules, up to 100% possible with SAP
fibers
- The granular dosing and metering systems are
adjustable for 3-dimensional control
Synthetic Fiber Blends
- Synthetic fibers of most types can be handled and
metered up to about 12mm in length
- Multiple synthetic fiber metering systems allow
complex blends and even 100% synthetic fiber webs
Pulp Defibration
- Commercial Kamas H-12 hammermills and knife mill
with two pulp unwinds processes 100mm wide fluff rolls with a full
selection of screens and with capability of handling nondebonded pulp,
non-roll waste paper, etc.
Bonding Methods
- Latex spray bonding, calendar bonding or thermal
bonding by through-dryer are all available
- Electrically heated rolls can be used for
compression or bonding
- Latex and thermal bonding can be used alone
together. For very high basis weights an oversized through-dryer
offers precise control and extra time-at-temperature capabilities
- Wide temperature capability and very long time-at-temperature
are possible
- The extremely capable four-roll heated calendar includes air doctors
for lightweights and can be configured for pattern bonding/embossing and
densifying at moderate or extremely high
Terms for Typical Projects
- US $4400/ 7 hour day
- Raw materials are provided by the customer and
returned at the end of the trial
- Wrapping/palleting/shipping expenses are charged to
the customer
- Customers renting more than 10 days/year receive
discounts, depending on volume
- Customer pilot plant equipment can be installed on
MTS's line and tested. Cost is based on specifics of the project
and duration
- Contract laboratory testing of fabrics can be done
on-site in our extensive testing lab, offering the most advanced testing
equipment and skilled operators
- Confidentiality is a proven commodity at MTS
