- Poor quality thread is installed, with uneven thickness and knots. Do not use old Soviet-era thread, always buy quality thread;
- The thread thickness does not match the selected needle. Thick thread in a thin needle is a common cause of breakage;
- the needle is incorrectly installed, bent or does not match the type of machine. Check which way the flat cut of the bulb is pointing and if an industrial machine needle is accidentally caught in a domestic machine. Make sure the needle is straight and sharp. Look in the manual to see how the needle should be installed in your particular machine;
- Excessive upper thread tension. Slacken the tension with the dial and check the machine on a test piece of the same fabric. If the tension cannot be adjusted, part of the mechanism may be broken and you should contact a service center.
How to change the needle in a brother sewing machine: useful tips
While sewing, it is often necessary to change the needle on the machine. The cause may be its bluntness or distortion, in which case the needle should be changed immediately, to prevent it from breaking or damaging the fabric. Another reason for needle replacement can be the choice of a special needle for a particular type of work. embroidery, decorative stitching. Replacing a needle is an easy procedure for most modern sewing machines.

Before changing a needle in a brother sewing machine, you should study the instructions with photos of the process, watch a video on the Internet and then follow the prescribed steps step by step.
Incorrectly positioned needle: the cause of needle breakage
A correctly installed needle has no backlash, is securely fastened in the needle holder, and sews neat, even stitches without tangles or thread breaks. If the needle when replacing incorrectly installed, its trajectory while sewing shifts.
The risk of an incorrectly installed needle is its breakage (
One of the risks of such an offset is hitting the needle plate. It will scratch and damage the fabric by snagging it with a burr. The needle from such a blow breaks and can cause injury to the seamstress.
Another, more serious risk of improperly installed needle is machine failure. Manufacturers make the distance between the hook of the sewing device and the needle in the lower position less than a millimeter to easily capture the thread and form a loop. If the needle is lowered while sewing in an offset pattern, it can hit the hook and break, damaging the hook as well.
How to replace a needle on a sewing machine
Before you change an old sewing machine needle for a new one, you need to make sure that the inserted needle is of high quality. To do this, place it on the table, flat side down, and check that the clearance between the needle and the table top is the same along its entire length. If it is uneven, it means the needle is bent and must not be used. Sewing with a bent needle carries a risk of breaking the needle and damaging the machine.
To change the needle, you need to loosen the locking screw on the needle clamp (
Start by disconnecting the machine from the power supply to change the needle. If you forget to turn it off, the machine will start and may injure or break if you accidentally press the “start” button. Before replacing the needle plate, place a piece of paper or a scrap of cloth over the needle plate to cover the hole. That way, a needle which has inadvertently slipped out of your fingers cannot fall through the slot inside the machine.
To change the needle, you will need to unscrew the screw that fixes the needle. To do this, use a special screwdriver that comes with the sewing machine. It is convenient because of its small size, just right for work in the confined space near the needle holder.

Professional seamstresses believe that when buying a machine brother should pay attention not only to the functionality of your favorite model, but also to the quality of the stitches. To do this, try out with the help of a salesman, as the machine sews straight and decorative stitches on a patchwork of fabric of different density. It is useful to pay attention to whether the thread tension is well regulated, whether the bobbin is wound, whether all the buttons work.
One of the criteria for choosing a sewing machine for the house is the number of operations performed. It is important and complete the machine with additional feet, which expands its capabilities. Examples of popular machine models are shown in the table below.

Design of a machine needle for brother
The needle is a hardened steel rod without impurities, which makes this material very durable. Additional strength is given by nickel or titanium plating. The base of the needle has a cylindrical bulb, one side of which is slanted and is called a “bald spot” for this. This cut clearly matches the groove in the needle holder and facilitates the insertion of the needle.
Steel needle shaft tapers towards the tip, ending in an eyelet and point (
Stem is slightly thicker at the bulb and tapered toward the tip. Grooves on both sides of the pin. The long one accommodates the needle while sewing and protects it from contact with fabric and abrasion. Short also holds the thread, but its main purpose is to hold it a little longer at the bottom, near the hook and ensure the formation of a loop when you lower the needle.
The tip of the needle can be shaped differently depending on the fabric to be treated:
- Middle point. for linen, suit, blouse and most other types;
- long strongly sharpened point. for tight fabrics like denim, twill;
- rounded tip for knitted fabrics;
- Slightly rounded point and big beveled tip for delicate thin fabrics;
- Tip-blade. for sewing leather.
Just above the point is the eye for threading the needle. Not only is its eye standard, it can be elongated for metallic needle threads, or wide and smooth-polished for woolen threads.
Types of brother needles or how to choose the right one
The basic principle by which needles are classified into types is according to the density of the fabric. The lighter the fabric, the thinner the needle, and vice versa. Types of needles for different materials have different numbers. these represent thickness in millimeters and inches (european and american system). To the numeric code of the needle manufacturers can add a letter designation. It indicates the kind of fabric you can use the needle for. For example, 80/12H is a universal needle with a thickness of 80 mm, designed to work with cotton, linen, fine wool fabrics.
The appropriate needle is the one that matches the density of the fabric being sewn (
Not only by number, but also by name, which will help you find your way around the needle. Some names of needles and their characteristics are given in the table below.
|Universal||Suitable for most fabrics: for thin blouses. 0 to 5; for medium suits. 5 to 0; for interior and coat fabrics. 0 to 10|
|Jeans||Works not only with denim, but also with vinyl and other heavily padded materials|
|Jersey||Stitches knitwear without synthetic additives|
|Stretch||Stitches stretchy, stretchy fabrics|
|Embroidery||Embroidery needle suitable for various types of fabrics and threads|
|Metallic||Equipped with special extended needle for sewing or embroidery with metallic threads|
|For leather||Specially sharpened needle makes it possible to not make punctures but cuts in the material, so that the leather is not torn by the tension of the threads|
|Double||Performs double stitch stitching, used to decorate products|

Lighting equipment allows you to improve the lighting of the work area and minimize eye strain. Everyone who has worked for at least an hour at a sewing machine without additional lighting, knows how tiring it is. Backlighting is especially important for visually impaired users. In modern modifications, lights are attached to the table or built into the body. Therefore, the need for additional lamps is eliminated.
Types of oils
Sewing equipment can be divided into two main types: domestic and industrial.
Domestic sewing machines are used when working with thin and medium fabrics, but are not designed for thick and coarse fabrics. In this technique uses a drip system of lubrication, or dry lubrication, where all the nodes are served with oil and for some time works without additional lubrication.
Industrial sewing machines are more complex machines. It contains microprocessors, and the equipment is controlled by special software. Such equipment is divided by the type of fabric with which you can work: light, medium, medium-heavy, heavy and extra heavy material.
Industrial sewing machines use an automatic lubrication system. Computer finds out by itself when it is necessary to service and sets the amount of oil which is supplied through special channels to the friction zones. These machines have a lubricated sump, through a window, where the oil level can be checked. In addition industrial equipment can be lubricated by dry or trickle lubrication, just as in domestic applications.
Mineral or synthetic oils can be used for both of these sewing machine types. Recommended lubricant type for specific equipment is generally identified in the operating instructions.
- Wide temperature working range from.40 °C to 200 °C
- High flowability
- High penetration
- Free of solvents and mineral fats
- Compatible with plastic and elastomeric parts
- Easy to rinse out with most solvents
- Prevents thread twisting and sticking, reduces thread breaks
- Protects against corrosion and oxidation
Among synthetic oils, silicone oils are the most popular. They are suitable for oiling threads, knives, blades, any plastic and rubber parts, all parts of the sewing machine.
Vaseline (white paraffin) is the most suitable mineral oil. It is watery white in color and is practically odorless and tasteless, since it is devoid of aromatic compounds. This sewing machine oil is especially requested for units that require clean lubrication.
- No odor and taste
- Safe for human health
- Has an antistatic effect
- Leaves no greasy residue
- Solvent free
- Protects against corrosion
- Improves sliding
- Protects against slipping
