Why Sewing Thread Needs Lubrication
The main function of sewing threads is to hold together parts that could be of textile, or leather, to form garments and other made-ups. While the sewing process is on, a needle contains a temperature of around 350 degrees C. If the thread is lubricated in the right way; it will prevent the line from breaking down in between the process.
Due to their excellent heat-resistant and lubricating properties, silicone polymers are considered the best ingredient for a good thread-lubricating formulation. The silicone sewing lubricant is a stainless, odorless lubricant for the Thread Industry. The thread lubricant deposits a stainless coating on the thread, and lubrication cools the needle during high-speed sewing, preventing thread burnout. It also prevents wear and tear of machine parts and increases seam strength loss due to abrasion while sewing. Other benefits include easier needle penetration & elimination of carbon, sizing, or adhesive buildups on the needle or hook.
6 Benefits of Lubricated Sewing Thread
- Provide good lubricity, cools the needle during high-speed sewing, preventing sewing thread burnout, and can make the sewing machine speed up to more than 7000 needles/minute;
- Good antistatic properties, providing excellent binding of sewing thread, that is, the thread is not easy to disperse. Because the thread is not one, but several strands are twisted together. If there is a lot of static electricity, the lines will separate;
- Lubricants should be capable of transferring from the thread to the needle, reducing the needle’s friction with the sewn material and thus its temperature;
- The difference between dynamic/static friction is small. In this way, the vibration of the sewing machine needle is small when it is running up and down, and it does not break or skip stitches. The stitches are very flat, which improves the sewing quality;
- Lubricants should be capable of transferring from the thread to the needle, reducing the needle’s friction with the sewn material and thus its temperature.
- Increases seam strength by preventing strength loss due to abrasion while sewing.
