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 seriesµ of Sewing Thread Lubricants:

It is important that

seamstresses like

Sylast LubricantspSuperior 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 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 giveoptimum 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

http://slidepdf.com/reader/full/sylast-thread-lubricant 9/24

Normal lubricants often create a non-homogeneous layer, resulting in

insufficient smoothness of the thread. With Sylast Series you get ahomogeneous 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.

http://slidepdf.com/reader/full/sylast-thread-lubricant 11/24

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, leadingto 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 thatcritical seams can be placed more easily even when conditions are not

optimal.
