Sewing is an intricate craft that combines artistry with technical precision. One of the key elements that can significantly impact the outcome of a sewing project is the sewing tension. Tension refers to the amount of force applied to the thread as it passes through the sewing machine, which determines how the stitches are formed. Meanwhile, interlining, a material placed between the fabric layers, plays a crucial role in enhancing the structure, durability, and overall appearance of the sewn item. As a leading Sewing Interlining supplier, I have witnessed firsthand how different types of interlining can influence sewing tension, and in this blog, I'll delve into the details.
Understanding Sewing Tension
Before exploring the influence of interlining on sewing tension, it's essential to understand what sewing tension is and how it works. Sewing tension is controlled by a series of mechanisms in the sewing machine, including the tension discs, bobbin case, and thread guides. These components work together to regulate the flow of the thread, ensuring that it forms balanced and consistent stitches.
When the tension is too tight, the stitches may pucker, and the fabric may distort. On the other hand, if the tension is too loose, the stitches may be uneven, and the thread may bunch up or break. Achieving the right tension is crucial for creating high - quality seams and ensuring the longevity of the sewn item.
Types of Sewing Interlining and Their Impact on Tension
There are several types of sewing interlining available in the market, each with its unique characteristics and properties. The most common types include woven, non - woven, and fusible interlinings.
Non - woven Interlining Fabric
Non - woven interlining fabric is made by bonding fibers together through a mechanical, chemical, or thermal process. It is known for its softness, flexibility, and lightweight nature. Non - woven Interlining Fabric is often used in garments where a subtle shaping effect is desired, such as blouses, shirts, and lightweight jackets.
When using non - woven interlining, the sewing tension may need to be adjusted slightly. The loose structure of non - woven interlining can cause the thread to pass through more easily compared to a tightly woven fabric. As a result, the tension may need to be increased slightly to prevent the stitches from becoming too loose. However, if the interlining is too thick or dense, it may also cause the thread to bind, requiring a decrease in tension to ensure smooth sewing.
Interlining Non Woven
Interlining Non Woven is similar to non - woven interlining fabric but is specifically designed for use as an interlining. It offers excellent stability and shape retention, making it suitable for structured garments such as coats, suits, and dresses.
The thickness and stiffness of interlining non - woven can have a significant impact on sewing tension. Thicker interlinings can create more resistance as the needle passes through the fabric layers, which may cause the thread to pull tighter. In this case, the tension may need to be reduced to prevent the stitches from puckering or breaking. Additionally, the stiffness of the interlining can affect the way the fabric moves through the sewing machine, so it's important to ensure that the feed dogs are adjusted correctly to maintain a consistent sewing speed.
Non Woven Fusible Interfacing
Non Woven Fusible Interfacing is a type of non - woven interlining that has an adhesive backing. It is applied to the fabric using heat, which fuses the interlining to the fabric. This type of interlining is popular because it is easy to use and provides a strong bond between the layers.
When sewing with non - woven fusible interfacing, the tension can be affected by the adhesive. The adhesive can make the fabric stiffer and more resistant to the passage of the thread. As a result, the tension may need to be adjusted to accommodate the change in the fabric's properties. If the tension is not adjusted properly, the stitches may appear uneven, or the thread may break during sewing.
Factors to Consider When Adjusting Tension for Interlining
When adjusting the sewing tension for interlining, several factors need to be considered:
Thickness of the Interlining
Thicker interlinings generally require more adjustment to the tension. As mentioned earlier, thicker materials can create more resistance, which may cause the thread to pull tighter. It's important to test the tension on a scrap piece of fabric with the interlining before starting the actual project.
Type of Fabric
The type of fabric being used in conjunction with the interlining also plays a role in tension adjustment. For example, a lightweight, delicate fabric may require a different tension setting compared to a heavy - duty, thick fabric. The combination of the fabric and interlining should be taken into account to achieve the best results.
Sewing Machine Settings
Different sewing machines have different tension control mechanisms. Some machines may have a more sensitive tension adjustment system than others. It's important to familiarize yourself with your sewing machine's settings and how to adjust the tension properly.
Tips for Adjusting Sewing Tension with Interlining
Here are some practical tips for adjusting sewing tension when working with interlining:
Test on Scrap Fabric
Before starting the actual project, cut a small piece of the fabric and interlining and sew a few test stitches. This will allow you to see how the thread behaves and make any necessary tension adjustments.
Make Small Adjustments
When adjusting the tension, make small incremental changes. It's easier to fine - tune the tension by making small adjustments rather than making large, sudden changes.
Check the Bobbin Tension
The bobbin tension can also affect the overall sewing tension. Make sure the bobbin is wound evenly and that the bobbin tension is set correctly.
Use the Right Needle
Using the right needle for the fabric and interlining combination is crucial. A needle that is too small may cause the thread to break, while a needle that is too large may leave large holes in the fabric.
Conclusion
As a Sewing Interlining supplier, I understand the importance of getting the sewing tension right when working with interlining. The type of interlining used can have a significant impact on the sewing tension, and it's essential to take the time to adjust the tension properly. By considering factors such as the thickness of the interlining, the type of fabric, and the sewing machine settings, and following the tips provided, you can achieve high - quality seams and create beautiful, long - lasting sewn items.
