A new era has begun for SML customers after the
Munich ITMA with the SML launch of a couple of improvements on its spinning
line product range. Both SML BCF spinning lines, monocolour and tricolour,
have been totally reworked, which provides several new, additional
The monocolour line - BCF 4 x 2/90 new edition - has now been approved to
run a practical output of 240 kg/h, based on 1,800 den and up. This results
in a daily yarn output of 5.7 tons/day!
The patented texturing unit has been improved in several details in order to
further increase the crimp. Electrical equipment is now installed in a 13
foot container box, which is air-conditioned and perfectly sealed against
spin finish fumes and dust. SML's main target is to develop a machine with
an excellent output/machine-cost ratio, and a waste percentage below 0.9 %.
The tricolour line - BCF 4 x 2/3 x 60-T new edition - produces 6.5 tons/day,
based on 2,100 den! This has become possible with the implemented
improvements and developments of the last months.
At the ITMA SML had its FDY line HT 2 x 2 C/60 on display, running FDY yarns
with a titer range of 200 to 3,000 denier.
Austrofil BCF Tricolour Spinning Line: Enabling creation of modern colour
effects for the carpet industry
Based on the excellent yarn quality -- highest crimp level and low
shrinkage -- from the BCF mono-colour line, SML decided to develop a BCF
tricolour line according to the future requirements of the carpet industry.

With reference to the successful business in compact
spinning lines for SML it has been interesting to meet a challenge wherein
the excellent BCF yarn properties from monocolour can be combined with
tricolour with new ways of colour separation. Thus a new type of spinning
line has been generated. It should be an instrument for the carpet industry
to create unique yarns according their own requirements and to meet the
trends of fashion.
AUSTROFIL BCF Tricolour 4x2 T:
SML extrusion technology with 4 stretching and texturising units "STU"
This BCF line is equipped with continuous, gravimetric dosing units and
three extruders. The extruder dimension of ō 60 mm, LD 28, ensures a total
output of at least 240 kg/h and a quick change of colour. Each extruder has
a screen belt filter and static mixer for high melt quality. The
distribution of colours is done in the spinning beam. Heating of the
spinning beam is performed by means of circulating thermo-oil.
The applied arrangement does not require a high system pressure. For each
STU three spinning pumps can be started individually and at different
speeds. Diameters of spinnerets of 110 mm allow a high number of single
filaments and the possible development of yarns with a low single titer and
a particular touch. Two quenching units with individual control together
with two segments for spin finish application allow the production of
different yarn titers at the same time (per 2 modules).
Simultaneous production of two individual yarn specifications (A and B),
variable in: yarn titer, spinneret, quenching, spin finish application and
processing speed. At the bottom part of the spinning section a new
arrangement for pre-intermingling in two positions allows the separation or
blending of colours. For a clear colour separation each yarn is
pre-intermingled and separated up to the inlet of the texturising unit. To
create melange effects the yarns pass the second position of
pre-intermingling, where all three yarns are put together in one
intermingling jet. A change of parts or modification is not necessary
between the melange and the sprinkle effect. Accordingly, yarns can either
run through position 1 or position 2 or through both positions and, of
course, at different air pressures to provide multiple possibilities for
colour separation or blending.
Clear Colour Separation:
Pre-intermingled yarns are separa-ted up to the
inlet of the texturising jet.
Ingenious design of jet ensures controlled plug
Good separation of colours is also maintained in
the texturised plug and final yarn.
After stretching the yarn is texturised, the compact
plug is cooled for a time of 15 seconds. Cooling is effected by a seamless
drum with a smooth surface, which is favourable for yarns of fine single
filaments. Further the yarn is drawn off. Downstream of duo 3 the yarn is
tangled by state-of-the-art intermingling jets and wound up on automatic
SML (Starlinger Maschinen Lenzing), with its head office in Lenzing -
Austria stands for high-tech extrusion technology based on nearly 40 years
of experience in Polymer processing. During the past 9 years, the Upper
Austrian machine manufacturer has specialised in the production of plastics-coextrusion
lines (multiple-layer-film lines) for the production of film and sheet,
laminates and in spinning lines for PP-multifilaments. SML has made a name
for itself in the international market by tailoring extrusion lines to
customer requirements and has established itself as technological market
leader in many product fields.
SML clearly aims to strengthen its position as technology leader in
coextrusion cast film lines, coextrusion calendering lines, extrusion
coating lines and AUSTROFIL multifilament spinning lines. This objective is
to be achieved through close co-operation with international research
institutes, leading universities in the field of plastics processing,
raw-material producers as well as with suppliers and customers.
Each newly developed extrusion line is tested at the SML factory together
with the customer under production conditions before delivery. Continuous
assistance and co-operation between the customer and SML are most important
services offered by SML after start-up of the extrusion line at customers
site. SML's Customer Service Centre is available to the customers
around-the-clock - worldwide.
SML currently employs 192 staff, and has achieved a turnover of around 60
million Euros in the year 2006. Nearly 100 % of the units are exported. The
main markets are the European countries, GUS, Central and South America,
North America as well as the Near and Far East. SML offices in Beijing -
China, in Kuala Lumpur - Malaysia, in Surabaya - Indonesia and in Chicago -
