Garment makers & consumers have very high expectation
The seam must meet a multiplicity of requirements. Consequently, the
requirements of the garment makers and the sewing industry are high on the
thread used to make seams. Production of seam must be quick & flawless, it
must withstand mechanical stress & it must meet the aesthetic & up-to-date
fashion expectations of consumers. They can fully unfold their capabilities
when they are brought up to peak performance by “Sylast series” of Sewing
Thread Lubricants:

A seam must

Sylast LubricantsSuperior performance in your exhaust
process:
The lubrication is initiated by pH adjustment and temperature raise.
The lubricant droplets grow together and form a homogeneous film on
the surface of the thread. Sylast-Series helps to make exhaust
process quick, simple & complete
Sylast film
Sylast lubricants for lick roll application have been optimized to wet
the lick roll with a uniform thin layer. When the thread comes into
contact with this layer, the lubricant is transferred to the thread and
spread out forming a homogeneous film on the surface of the
thread.
Sylast series range includes lubricants that are formulated to give
optimum performance in dosing pump application. They fully
cover the thread forming a uniform lubricant film. They are so
stable that very little contamination builds up in the machine. This
reduces cleaning costs & idle time to a minimum
Normal lubricants often create a non-homogeneous layer, resulting in
insufficient smoothness of the thread. With Sylast Series you get a
homogeneous lubrication. Regardless of whether you use the exhaust
process, a kiss-roll or dosing pump, the lubrication result in perfect in all
respects.
Without antistatic agents, a very high static charge builds up on thread
during sewing. Threads do not run smoothly, and this inevitably results in
poor sewing & poor seam quality.
Standard lubricants hardly reduce friction on thread, & they are a
significant factor in needle overheating without heat protection, sewing
thread made of synthetic fiber will melt. This weakens the thread, leading
to crust formation at needle. The result is thread breakage and limits on
stitch frequency. Sewing thread treated with Sylast lubricant glides
smoothly into the fabric. It provides heat protection for threads made of
synthetic fiber. With Sylast you can sew at high speeds without the risk of
thread breakage.
In the sewing industry, there often is not enough time to adjust sewing
machine parameters to exactly match the sewing thread & the fabric. The
consequences, for example when working with thin or smooth materials,
are often fatal-crinkled seams & frustrated seamstresses.
Standard lubricants have narrow application window , & this often leads to
problems in sewing process.
LNCI optimizes thread lubricants for a wide application window, so that
critical seams can be placed more easily even when conditions are not
optimal.

Disadvantage of hard waxing :
oIrregular take-up
oPoor reproducibility
oNo constant friction
oHigh static charge
oLoss of paraffin during storage
oParaffin deposits
oLow winding speed
oYarn breakage
oUnsteady fibre run.
