Bobbin in India refers to a small reel or cylinder that is designed to hold sewing thread. Sewing threads are used in the sewing machine and can be manufactured with different types of materials.
The bobbin is a key feature of all sewing machines. Without it, seaming fabric would be impossible. The bobbin provides tension to help control how the thread is pulled from the spool, so seams can be sewn evenly. It works in conjunction with the shuttle or carrier that moves the thread around as stitches are formed.
Depending on the use and purpose, there are different types of bobbins.
A core thread bobbin has a hollow center, just like the standard bobbin. The difference between them is that it allows threads to be wound around it. Winding around it may use the bobbin winder on the sewing machine or hand-wound sewing thread on it. Some core thread bobbins have flanges that may help guide sewing thread, so it doesn't get tangled when sewing.
The electric bobbin winder helps to automatically wind thread onto bobbins without having to supervise or press any buttons after starting the machine. These are usually used in industrial sewing setups to save time and produce more bobbins quickly.
Plastic bobbins are used in almost all types of sewing. They are made of plastic and have a small diameter shaft fitted with a central disc to hold the thread. Plastic bobbins usually come in two sizes: standard and oversized. The standard size is common with home sewing machines, while oversized ones are used for larger threads and stitches. Threads tend to be easy to see and identify when used with plastic bobbins because of the transparency or translucence of the material.
Magnetic bobbins are fabricated with steel discs and have little plastic or metal rims that surround them. These kinds of bobbins are accurate and have great tension when utilized in embroidery sewing machines. The steel disc's magnetic property causes the sewing machine to automatically stop or break when the bobbin is almost empty. This indicates that the user needs to change or refill the bobbin.
This type of bobbin is specialized and is used in blind hem sewing. Blind hems are seams that are almost invisible on the outer side of a garment or fabric. The inside counterpart is all visible. This kind of hem is usually utilized on trousers, skirts, and the limbs of jackets. To make blind hems, specialized sewing machines require blind hem bobbins. They produce chain stitches that are easily identifiable on the inside of the fabric but not on the outside. This makes them perfect for neat, invisible finishing on hem lines.
Material:
The materials of the bobbin may vary according to its usage. The bobbins used for sewing machines are mostly made of plastic, while industrial steel bobbins are made of metal, alloy, or steel for durability and strength.
Size:
Bobbins come in various sized and shaped components. The most common type are cylindrical with a center axle area to fit onto a machine. They are labeled as class 15 bobbins in India. The other types are L and M-shaped bobbins. These are all-purpose sewing machine bobbins for low shank sewing machines.
Weight:
Bobbins are lightweight components. Usually, the standards of the bobbin weights won't be mentioned, as they are so light that detailed weight specifications are not required.
Thread capacity:
The thread capacity of the bobbin refers to how many threads can be placed in the base of the bobbin. Usually, bobbins come with a threading system on their surface, and the threading depth will also vary depending on the size of the bobbin. Standard-sized or class 15 bobbins in India can usually accommodate 60 to 70 yards of thread, while bigger-sized bobbins may be able to hold a lot more thread.
Bobbin maintenance is very important, especially if they are used in sewing machines that are used commercially or industrially. Well-maintained bobbins will ensure that customers do not come back complaining of sewing issues.
Cleaning:
It is always good to clean the bobbin regularly to take out dust lint and other debris. One should use a lint brush or vacuum nozzle to remove any debris from the bobbin compartments. This will ensure that the bobbins function smoothly with minimal interruption.
Lubrication:
If the bobbin case has moving parts or if the bobbin helps in moving the thread, it is essential that it be lubricated from time to time to reduce friction and overheating. Follow the sewing machine manual to identify the correct parts to lubricate and use only high-quality machine oil for this purpose. The bobbin will run more smoothly, and the wear and tear of parts will reduce significantly.
Inspection:
Regular inspection of the bobbin and its parts is necessary to see if there are any worn-out, damaged, or frayed areas. If any, they should be replaced immediately to avoid malfunctioning of the sewing machine.
The use of sewing bobbins is as diverse as the industries that rely on sewing machines. Below are some common industry scenarios where sewing bobbins are applied:
Apparel Manufacturing
Apparel manufacturing is the biggest user of sewing bobbins. Besides, many different kinds of sewing bobbins are needed to make various fabrics and clothes in different colors. For example, domestic bobbin cases with double-thread bobbins are commonly used to sew lightweight stretchy fabrics such as T-shirts. On the other hand, industrial bobbin cases may sew heavier material using its single thread.
Quilting
Quilting projects often use large bobbins to decrease how frequently the quilter must change the bobbin. Additionally, specialized quilting machines have specific bobbin sizes.
Embroidery
Embroidery work often utilizes pre-wound bobbins with consistent tension and fewer thread breaks.
Leatherwork
Leatherwork requires strong, bulky thread bobbins to ensure seams can support the weight of the leather and any wear and tear.
Upholstery
Upholstery projects also need durable upholstery thread bobbins to help easily sew furniture, car, and marine covers.
Automotive Industry
Automotive seat covers, airbags, and interior linings are some examples of items that may be made with sewing bobbins. In many cases, industrial-sized bobbins are used, and tougher, more durable threads are needed.
Medical Devices
Some medical devices, such as surgical sutures and restraint straps, may be produced using sewing bobbins. Precision and consistency are crucial for these devices to function correctly and remain safe.
Specialized Applications
Sewing bobbins may also be used in specialty fields, such as aerospace, where specialized fabrics must be used as lightweight and strong materials.
Choosing the suitable bobbin requires careful consideration of various factors to ensure compatibility, functionality, and specific sewing needs.
Understand the Sewing Machine Requirements:
It's crucial to know the specific bobbin requirements of the sewing machine. Different sewing machines use particular bobbin types, sizes, and shapes.
Check the machines manual and determine the recommended bobbin.
Bobbin Types:
Familiarize oneself with the different bobbin types and their uses. The class 15 bobbins are round and typically used in home sewing machines. As previously stated, the class 66 bobbins are round and slightly larger than the class 15 bobbins. They are often used in some older singer sewing machines. The class 173n bobbins are larger than class 15 and 66 bobbins and are generally used in industrial sewing machines. The plastic bobbin is manufactured from sturdy plastic and is more popular among sewers. Metal bobbins are manufactured from lightweight metals such as aluminum or brass. They are more popular with sewers who use vintage or specific models of machines made, which are made, which are compatible with metal bobbins.
Bobbin Size:
Bobbins come in different sizes, affecting the amount of thread they hold. Consider the sewing projects and thread capacity needed. Choosing a size that balances thread capacity and machine compatibility is essential.
Build Material:
Bobbin build material can affect performance and durability. Choose an option that aligns with the sewing needs.
For projects requiring frequent thread changes or high-volume sewing, selecting a bobbin that holds more thread is beneficial.
Considering any special requirements, some sewing projects have unique needs, like using specific bobbin materials or sizes.
Q1: How is the bobbin thread made?
A1: The bobbin thread is typically made from the same fabrics and fibers as sewing threads. This can include cotton, polyester, nylon, silk, or a blend of these materials. The thread-making process involves spinning the fiber into a tight strand and then winding it onto small cylindrical spools known as bobbins.
Q2: How does the bobbin holder work?
A2: The bobbin holder, or bobbin case, keeps the bobbin in place while the thread is unrolled during the stitching process. It also controls the tension of the thread, ensuring the stitch is tight and secure.
Q3: How does a bobbin winder work?
A3: A bobbin winder winds thread onto a bobbin for sewing machines. It typically does this by rotating the bobbin in one direction while feeding the thread from the spool in another direction. This ensures that the thread is evenly wound onto the bobbin for subsequent use in the sewing machine.
Q4: What are the different types of sewing machine bobbins?
A4: There are mainly two types of bobbins: the shuttles or bobbin cases type and the rotary hook type. The former are flat discs, usually of metal, with a central hole, and the latter are cylindrical. Another way to distinguish bobbins is by whether they are pre-wound or not.
