1. What are thread breaks?

In embroidery, "thread breaks" refer to the sudden separation of the embroidery thread being used during the embroidery process, resulting in the thread end disconnecting from the needle and making it impossible to continue stitching. Thread breaks can lead to the following issues:

• Discontinuous embroidery: When the thread breaks, the embroidery thread segment between the thread end and the needle disconnects, causing interruptions and discontinuities in the stitching lines, which affects the overall appearance and quality of the embroidery work.
• Difficulty in handling thread ends: When the thread breaks, the thread end may slip into the fabric, making it challenging to locate and handle, increasing the difficulty of repairing the embroidery work and potentially leading to thread nests.
• Impact on embroidery stability: Thread breaks disrupt the continuity and stability of the embroidery thread. If multiple thread breaks occur, the structure and strength of the embroidery work may be compromised.
• Increased time and workload: When a thread break happens, you need to stop, reorganize, and restart the embroidery. This increases the time and workload required for embroidery, prolonging the completion time.

In summary, thread breaks can interrupt the embroidery process and be accompanied by issues such as thread nests and misaligned stitches.

2. What are the common causes of thread breaks?

a) Excessive tension

The most common cause of thread breaks is improper tension. Typically, excessive tension makes the thread more prone to breaking.When the embroidery thread is subjected to excessive tension, it stretches beyond its strength limit and breaks. Just imagine holding a thin rope and suddenly pulling it with great force—it's likely to break in your hands. The same applies to embroidery thread.Moreover, when the tension is too high and the thread is overly stretched, it becomes taut and susceptible to pressure from uneven, rough, or sharp surfaces of the fabric. These objects exert additional pressure on the thread, leading to breaks at these rough spots.It's important to note that finer embroidery threads are more susceptible to breaking due to excessive tension. Fine threads are generally more fragile, with lower strength and stretching capabilities. Therefore, extra care should be taken to control tension when using fine threads for embroidery, avoiding excessive tightening.

b) Needle size too small

Using the wrong needle size in embroidery projects can cause excessive friction and tension on the thread, leading to breaks.If you use a needle that is too small, it may not provide enough space for the embroidery thread to pass through. When attempting to thread thicker embroidery thread through a small needle eye, the thread experiences excessive friction and tension. This excessive friction and tension exert additional pressure on the thread, surpassing its strength limit and causing it to break.Additionally, thread breaks can occur when the needle is not properly inserted into the machine, the needle is bent, the needle eye is rough or sharp, or the needle groove is too shallow.

c) Poor thread quality

The quality of embroidery thread is crucial for successful embroidery. If you use low-quality thread, you may encounter frequent thread breaks.Poor thread quality typically refers to insufficient thread strength or unstable thread construction. This means that the thread is more prone to breaking during the embroidery process.Insufficient thread strength may result from using cheap or low-quality materials. The fibers in such thread may not be strong enough and easily break under certain tension. Additionally, unstable thread construction refers to a lack of strong bonding between the fibers, leading to loose or breakable thread.Furthermore, the coating or coloring of the thread can also affect its quality. Low-quality coating or coloring may result in a rough or uneven surface of the thread, increasing friction on the fabric and causing breaks.

d) Machine component wear

Sometimes, when there is wear or damage to the parts of the embroidery machine, the embroidery thread may encounter obstacles or be compromised, leading to thread breaks. A common issue is the presence of burrs on the machine components. Burrs refer to protrusions or rough areas on the embroidery machine that can catch and pull the embroidery thread, causing it to break.

Besides the previously mentioned needle wear, common machine component wear includes the following situations:

• Needle plate wear: The needle plate is the metal plate on the embroidery machine through which the needle passes. After prolonged use, the surface of the needle plate may become worn or rough. These worn areas can catch the embroidery thread and lead to breaks. Regularly inspect the needle plate, and if you notice any protrusions, roughness, or damage, replace it promptly.
• Other component wear: Apart from the needle and needle plate, other parts of the embroidery machine, such as tension devices and wire connectors, can also experience wear. The wear of these components can result in unstable thread tension or loose wire connections, leading to thread breaks. Regularly inspect and maintain these components to ensure their proper functioning and stability.

Additionally, if the embroidery machine is not regularly cleaned and maintained, dust, fibers, or other debris may accumulate on its components. These debris can cause the formation of burrs and result in the embroidery thread being pulled and damaged, leading to breaks.

e) Improper threading of the machine:

Incorrect threading of the embroidery machine can lead to thread breakage issues. Proper threading is a crucial step to ensure the smooth operation of the embroidery machine and continuous flow of the embroidery thread. If the threading is incorrect, the embroidery thread may encounter obstacles or tension, resulting in breaks. Here are some possible threading errors:

• Incorrect placement of the thread spool: The thread spool is where the embroidery thread is placed. If the thread spool is not correctly placed on the embroidery machine, the embroidery thread cannot smoothly pass through the thread path, making it prone to breakage.
• Incorrect thread path: The thread path is the route the embroidery thread takes from the thread spool to the needle. If the thread path is incorrect, the embroidery thread may get stuck or experience tension, leading to breaks.
• Failure to thread through the needle eye properly: The needle eye is the part of the embroidery needle through which the embroidery thread needs to pass. If the embroidery thread is not threaded through the needle eye correctly, it may get caught or experience tension, resulting in thread breaks.

3. What measures can you take to prevent thread breaks?

Now that we have identified common causes of thread breaks, let's discuss some preventive measures to avoid thread breaks from occurring.

a) Proper tension adjustment

Achieving the correct tension is crucial for preventing thread breaks. It is recommended to start with moderate tension and make small adjustments until you find the optimal tension for a particular project.

Consider the type and thickness of the embroidery thread being used when making adjustments. Different types and thicknesses of thread may have different tension requirements. Fine threads may require looser tension, while thicker threads may require tighter tension. Understand the characteristics of the thread being used and make appropriate tension adjustments based on its properties.

By paying attention to and adjusting the tension, you can reduce the likelihood of thread breaks caused by excessive tension, ensuring the continuity and stability of the embroidery thread.

b) Choosing the correct needle:

Selecting the appropriate needle for your embroidery project is crucial. When choosing an embroidery needle, consider the fabric type, thread thickness, and design complexity. Using the correct needle size can minimize thread friction and tension, thus reducing the likelihood of breaks.

To avoid thread breaks caused by using the wrong needle size, you can take the following measures:

• Choose the appropriate needle size, typically determined based on the thickness of the embroidery thread and the fabric. Finer embroidery threads and fabrics usually require finer needles, while thicker threads and thicker fabrics may require larger needles.
• Conduct tests before embroidering. Try embroidering small samples on the fabric using different needle sizes, and observe how the thread passes through and holds in place. Select the size that provides the best results.
• Ensure the needle tip is smooth and sharp. Dull needles can damage the structure and strength of the embroidery thread, increasing the risk of breaks.
• Pay attention to the angle and force applied when using the embroidery needle. Avoid exerting excessive force or bending the needle tip too much, as this can exert additional tension and pressure on the embroidery thread.
