Spun polyester thread

Types of spun polyester thread

Spun polyester thread is a type of thread made from short strands of polyester that are twisted together to form a single thread. This process, similar to spinning cotton, results in a thread that has some of the qualities of cotton, such as softness and flexibility. However, it also retains the strength, durability, and moisture-wicking properties of polyester. The result is a thread that is well-suited for a wide range of sewing applications, including both hand and machine sewing. Here are some types of spun polyester thread:

• General-Purpose Spun Polyester Thread

  This type of thread is versatile and can be used for a wide range of sewing applications, including garment construction, home decor, and quilting. It is suitable for both machine and hand sewing and works well with most fabrics. General-purpose spun polyester thread is known for its strength, durability, and resistance to shrinking and fading.

• Heavy-Duty Spun Polyester Thread

  This type of thread is designed for sewing heavy fabrics and materials such as denim, canvas, and upholstery fabrics. It is thicker and stronger than general-purpose thread, making it suitable for heavy-duty sewing applications such as making curtains, tents, and other outdoor gear. Heavy-duty spun polyester thread is also used in industrial sewing applications.

• Quilting Spun Polyester Thread

  This type of thread is specifically designed for quilting applications. It is finer than general-purpose thread, allowing for smaller stitches that result in a smoother quilted surface. Quilting spun polyester thread is available in a wide range of colors and can be used for both machine and hand quilting.

• Embellishing Spun Polyester Thread

  This type of thread is used for decorative sewing applications such as embroidery, applique, and decorative stitching. It is available in a wide range of colors, finishes, and weights, allowing for a variety of decorative effects. Embellishing spun polyester thread is known for its colorfastness and ability to retain its shape and finish after washing.

• Serger Spun Polyester Thread

  This thread is specifically designed for use in serger or overlock machines. It is available in large cones to accommodate the multiple threads used in serger sewing. Serger spun polyester thread is known for its ability to stretch and recover, making it suitable for sewing knit and stretch fabrics.

Design of spun polyester threads

When selecting a spun polyester thread, the design aspects to consider include the thread's color, texture, thickness, and type of twist.

• Color

  The color of spun polyester threads varies widely. Some are bright, like red, yellow, and blue. Others are more muted, like gray, black, and white. Some threads have a single color along their length. Others may have two or more colors twisted together. This creates a mixed color effect. The choice of color often depends on the type of sewing project. For instance, bright colors are suitable for quilting or decorative stitching. On the other hand, muted colors work well for most garment sewing. Spun polyester threads can also come in pre-selected color sets. These sets offer a range of colors that match or complement each other.

• Texture

  Spun polyester threads have different textures. Some feel smooth to the touch. Others may feel a bit rough. The smooth threads are great for fine sewing. They pass through the needle easily. The rough threads are better for heavy fabrics. They provide a good grip. The texture also affects how the thread behaves when sewing. Smooth threads make straight stitches easily. Rough threads may cause the needle to skip. The texture of the thread can also affect the look of the finished project. Smooth threads give a neat, clean look. Rough threads may create a more textured appearance. Thread makers often twist fibers together to form a thread. This twist can be tight or loose. A tight twist gives a firm thread. A loose twist results in a softer thread.

• Thickness

  The thickness of spun polyester threads can vary. Some threads are very thin. Others are quite thick. The thin threads are good for light fabrics. They work well with small needles. The thick threads are better for heavy fabrics. They need larger needles. The thickness of the thread affects the size of the stitches. Thin threads make small, fine stitches. Thick threads create larger, bolder stitches. Thread thickness is often measured in weights. A lower weight number means a thicker thread. A higher number indicates a thinner thread. This system helps sewists choose the right thread for their project.

• Twist Type

  Spun polyester threads have different twist types. Some threads are single-ply. They have one strand twisted into a thread. Other threads are multi-ply. They have two or more strands twisted together. The twist type affects the thread's strength and flexibility. Single-ply threads are softer. They drape better. Multi-ply threads are firmer and stronger. They hold up well under tension. This makes them suitable for heavy fabrics. The twist direction also matters. Some threads are Z-twist. Others are S-twist. The twist direction can affect the thread's performance in sewing machines.

Wearing/Matching suggestions of spun polyester thread

Spun polyester threads are versatile and can be used for various applications. Here are some wearing and matching suggestions based on their characteristics:

• Wearing Suggestions:

  When using spun polyester threads for sewing, opt for a needle that suits the thread's thickness and type. Universal needles are a good choice for most spun polyester threads. Ensure the needle size matches the thread size to prevent thread breaks or fabric damage. For machine sewing, set the tension according to the thread type. Spun polyester threads usually require slightly lower tension than cotton threads. Test on a scrap fabric before starting your project to adjust the tension if needed.

• Matching Suggestions:

  Matching the right thread to your fabric is crucial for a successful sewing project. For lightweight fabrics like silk or chiffon, choose a fine-spun polyester thread to avoid adding weight and bulk to the seams. A 100-weight thread works well for these fabrics. For medium-weight fabrics like cotton or linen, a 40-weight spun polyester thread is ideal. It provides adequate strength and flexibility for medium-weight fabrics without causing puckering or distortion.

• Wearing Suggestions:

  When using spun polyester threads for embroidery, select a thread designed specifically for embroidery. These threads are usually finer and have a higher sheen, adding a decorative touch to your embroidery projects. Choose a needle with a larger eye to accommodate the finer thread without causing friction or damage. A 75/11 or 80/12 needle works well for most embroidery threads. Adjust the machine's tension to achieve even stitching and prevent thread breakage.

• Matching Suggestions:

  Matching the right thread for embroidery is essential for achieving professional-looking results. For delicate fabrics like lace or organza, choose a high-quality, fine-spun polyester embroidery thread. A 60-weight thread is suitable for these fabrics as it allows for precise and intricate stitching. For heavier fabrics like denim or canvas, opt for a 40-weight embroidery thread. It provides the necessary strength to withstand the fabric's weight and texture while maintaining a smooth stitching process.

• Wearing Suggestions:

  When using spun polyester threads for quilting, opt for a thread that matches the weight of your quilt sandwich. A 40-weight or 50-weight spun polyester thread works well for most quilting projects. Choose a needle suitable for quilting, such as a 75/11 or 80/12 needle. Adjust the machine's tension to ensure even stitching and prevent thread nesting or puckering. Test on a scrap quilt sandwich to fine-tune the tension if necessary.
