How To Sew Silk Fabrics in 5 Steps?
Before moving on to delicate, drapey textiles like silk, it is advised to have learned the fundamentals of sewing with cotton or linen-type fabrics. This will give you a feel for how the sewing machine works and how to control the fabric while sewing.
1. Pre-Washing
When it comes to sewing with silk fabrics, there are a few key things you need to keep in mind. First of all, always pre-wash your fabric. Silk shrinks at a rate of 4-10%, so if you don't wash it beforehand, you'll run the risk of your garment shrinking after you've already sewn it. Pre-washing will also help to remove any dirt or impurities from the fabric.
Second, be sure to use a silk softener when washing. This will not only clean the fabric but also reduce static electricity. And finally, make sure to give the fabric plenty of time to soak. A minimum of four hours is recommended. This will ensure that the fabric has absorbed enough water and won't shrink later on.
2. Cutting
Once you have pre-washed your silk, the next step is to cut the fabric. Make sure to iron the fabric flat before cutting, this will help ensure that you get a clean, crisp cut. You may also want to consider adding an interlining prior to cutting, as this will provide some stability and make the fabric easier to work with.
When cutting silk, take your time and be precise. The lightweight nature of the fabric can make it tricky to work with, but taking care not to skimp on the cut will pay off in the end.
3. Sewing
Sewing silk is much like sewing any other type of fabric. Be sure to use a needle that is designed for sewing delicate fabrics such as silk. In fact, not all silk fabrics need to be sewn with the finest sewing needle. Depending on the fabric thickness and your sewing ability, you can pick the appropriate needle size freely. Generally, the thinner the fabric is, the finer needle you will need to use.
When sewing silk, be sure to use a straight stitch. A straight stitch is stronger than a zigzag stitch and will prevent the fabric from tearing easily. However, rushed stitching can cause problems such as missed stitches or uneven hems, so be sure to sew slowly and carefully to avoid making any mistakes.
4. Interlining
Interlining is an important step in sewing silk fabrics. Interlining helps to stabilize the fabric and prevents it from stretching or tearing easily. We recommend using an interlining that is dedicated to silk fabrics. This type of interlining will be much thinner and less bulky than other types, making it ideal for use with delicate fabrics.
When applying interlining, be sure to do so evenly so that there are no wrinkles or creases in the fabric. Once you have applied the interlining, smooth it out so that it lies flat against the surface of the fabric. If there are any wrinkles or creases in the interlining, they will show through when you sew the garment and will ruin its appearance.
5. Overlocking and Hemming
The final steps in sewing Silk fabrics are overlocking and hemming. Overlocking helps to prevent the raw edges of the fabric from fraying or unraveling. While hemming can help to give the garment a finished look and prevents it from coming undone.
Due to the lightweight texture of silk fabrics, they can be challenging to deal with. However, this can be easily remedied by double overlocking the raw edges of the fabric, as this will help to stabilize the fabric and make it easier to work with.
When overlocking, be sure to trim away any excess threads so that they do not show through when you sew the garment. And when hemming, be sure to iron out any wrinkles or creases before you begin stitching. Once you have finished overlocking and hemming procedures, your garment is ready to be worn!
Special Tips for Sewing With Delicate Silk Fabrics
Now that you know the basics of sewing with Silk fabrics, here are some special tips that will help you get the best results:
1. Use the Right Needle
Let's start with the most important tool in your sewing kit: the needle. Here a No. 9 German needle is the best fit, as it is fine enough to not damage the fabric but also strong enough to sew through multiple layers. Additionally, the stitches will be virtually invisible, which makes it the best choice when working with delicate fabrics.
2. Choose the Right Sewing Thread
When sewing with delicate fabrics such as silk, it is crucial to choose the right sewing thread. We recommend using a No. 50 or 60 silk thread (polyester filament-made). This thread is much thinner than the average polyester sewing thread, but its tensile strength is excellent, meaning that it is less likely to break during sewing. In addition, this type of thread is less likely to leave behind noticeable stitches on the fabric surface.
3. Adjust the Height of the Feed Dog
Another crucial factor to consider when sewing with delicate fabrics is the height of the feed dog. The feed dog is a component of the sewing machine that moves the fabric through the machine during sewing. If the feed dog is set too high, the silk fabric can be pulled and distorted during sewing. On the other hand, if it is set too low, the fabric will not feed properly and sewing will be more difficult.
When sewing silk, it's better to lower the height of the feed dog to about 0.4mm. This will help to prevent the fabric from being pulled or distorted during sewing.
4. Adjust the Bobbin Pressure of the Core Sleeve
The core sleeve is the part of the sewing machine that holds the bobbin in place. The bobbin is the small spool of thread that is used to sew the bottom layer of stitches. The tension of the bobbin thread is controlled by the pressure of the core sleeve.
If the pressure on the core sleeve is too high, it can cause damage to delicate fabrics such as silk. On the other hand, if the pressure is too low, the fabric will not feed properly and sewing will be more difficult.
When sewing with delicate silk fabrics, it is best to adjust the pressure of the core sleeve by pinching the thread with your hand and gently shaking it. This can make the bobbin sleeve fall slowly and evenly so that the silk fabric will not be easily wrinkled.
5. Adjust the Tension of the Stitching
The tension of the stitching is one of the most important factors to consider when sewing with delicate fabrics. If the tension is too high, it can damage the fabric or cause the stitches to pucker. However, if the tension is too low, the stitches will be loose and easily come undone.
When sewing with delicate fabrics such as silk, it is best to adjust the tension of your stitching so that the top and bottom stitches are the same sizes. This can be done by loosening the top tension knob until the stitches are the same size.
Conclusion
Sewing with delicate fabrics can be a challenge, but by following these tips, you can sew silk and other delicate fabrics with ease. Just remember to do all you can to protect the fabric, such as using the right sewing thread and adjusting the tension of your stitches. With a little bit of patience and extra care, you can create beautiful garments and other projects that are sure to impress.
