The document discusses the requirements and expectations for sewing thread from both garment makers and consumers. It must meet technical requirements for production as well as aesthetic fashion expectations. A variety of lubricants are introduced that optimize thread performance for different application methods and provide benefits such as homogenous coating, reduced friction and static, heat protection, and a wide application window. LNCI offers a full range of lubricants suitable for different fiber types and processing needs.

2. 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 lot is expected of sewing thread Embroidery yarn should shine & embellish Robust Sewing process are crucial It is important that seamstresses like working with your thread Thread must be gentle on the skin A seam must hold & look good

3. Sewing thread lubricants for exhaust method & lick roll application LNCI offers a complete range of sewing thread lubricants that are suitable for use with all application techniques: Exhaust Method Lick Roll Method / Dosing pump

4. Constant Concentration along bobbin cross section Temperature Liquor flow pH control Pumping cycles Residence time Yield

5. Rinsed Yarn Buffer Soda Sylast Series 8 mins 8 mins 25ºC 2ºC/min 60-70ºC Draining 8 mins pH measurement: 7.0-7.5 (As indicated in the technical leaflet) Pumping cycle(Alternating): 3 min inside-outside 5 min outside-inside

6. Sylast Lubricants  Superior 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

7. 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.

8. 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

9. 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.

10. 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.

11. 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.

12. 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. LNCI optimizes thread lubricants for a wide application window Standard lubricants have narrow application window

13. Customer benefits during production of sewing thread: Optimal formulation for exhaust, kiss-roll and dosing pump. Simple, reliable lubrication. Homogeneous solid add-on along the bobbin cross-section during the exhaust process. Perfect results during application with kiss-roll or dosing pump. Nearly no influence on tensile strength. Stable emulsions, even under extreme conditions. No influence on rubbing or colour fastness. 100% exhaustion.

14. Customer benefits during sewing: Good gliding and minimal friction for easy sewing. Constant friction values for constant sewing parameters. Antistatic properties for optimal running behaviour. Effective heat protection prevents thread melting & formation of deposits on the needle. No corrosion on machine parts. Non-critical when stitch frequencies vary significantly. Constant thread characteristics even under extreme climatic conditions. Constant seam thickness. Wide application window, even when technical sewing conditions are unfavorable. Fast, productive sewing with no thread breakage. Reduced reject rate. Satisfied seamstresses. Productive, efficient sewing operations.

15. Disadvantage of hard waxing : Irregular take-up Poor reproducibility No constant friction High static charge Loss of paraffin during storage Paraffin deposits Low winding speed Yarn breakage Unsteady fibre run. Wet waxing with “Sylast” is the technology of choice

16. Sylast Oil in water Inducing lubricant Yarn coating emulsion film formation Completed Lubricant Water growing together of Sylast lubricant Water lubricant droplets film

17. Ordinary two step process: 2 nd step Hard-waxing Dyeing Softening + Wet-waxing Combo-Process with Sylast:

18. Wet-waxing and softening in the dyeing unit, directly after the dyeing process. Ingeniously simple” One pot process” Good sliding properties & soft handle through finishing at yarn level. Excellent results & lower costs. For all types of yarn. For practically all applications such as socks, over wear, body wear etc.

19. Technical benefits: Extremely thin & homogeneous coating of the yarn with high-performance lubricant. Greatly reduced friction, abrasion & static charge. Constant coefficients of friction in every speed range. Operational benefits: Simplest handling No intermediate steps, directly after dyeing Little fibre fly & no deposits on the processing machines Efficient: Economical due to practically 100% yield Cost saving through simplification of process flow Environment- friendly because next to nothing remains in the liquor
