How to pick up needles for a sewing machine: a complete guide to choosing

Passage stitches, puffs on fabrics or a characteristic knock when lowering the needle driver most often indicate that an inappropriate needle is installed in the machine. Diameter of the rod And the shape of the tip must strictly correspond to the density of the material being processed, otherwise even the most expensive technique will not be able to perform a high-quality stitch. The wrong choice of consumable element leads to damage not only to the tissue, but also to the very shuttle-knotTherefore, it is impossible to ignore the marking on the packaging or the needle body.

Understanding the numbering system and design features avoids most sewing problems. European system (metric) refers to the diameter of the needle in hundredths of a millimeter, while the American uses conventional units, which often causes confusion among beginners. A properly selected needle freely passes through the fibers of the tissue, without pushing them excessively and leaving no visible punctures, while the eye should be wide enough for the thread to slide smoothly.

Modern sewing machines require the use of needles with a certain type of attachment, and an attempt to install an inappropriate option can result in a breakdown of the mechanism. Unlike hand needles, machine needles have a specific shape. flaskThis varies depending on the manufacturer of the equipment. Below we will discuss in detail how to decipher the numbers on the package and choose the perfect tool for your task.

Facilities and flasks types

The first thing to start with is to determine the compatibility of the shape of the tailing machine with your model of sewing machine. Most of the household cars work with standard system 130/705 HIt has a flat cut on one side and a round cut on the other. There are exceptions, however: for example, older models. Zinger or specific overlocks may require a needle with a round bulb or a misaligned eye. Installing a needle with an inappropriate geometry of the tail will cause the tip to not meet the shuttle at the right point, which will cause stitches to pass or thread break.

It is important to pay attention to the length of the needle, as in industrial machines this parameter is critical, although in household models it is standardized. If you use a modern computerized machine, it can be particularly sensitive to the needle mounting height relative to the needle. nucleo-ruler. The wrong height will lead to a failure in the operation of the sensors or a mechanical impact of the needle on the foot.

⚠️ Warning: Never try to force a needle unless it enters the needle to the point. This is a sure sign that the mounting system does not match your machine, and further pressure will lead to deformation of the needle driver.

Decoding of markings and size table

The package and the needle itself always have double numbering, for example 80/12 or 100/16. The first digit (80, 100) is the metric size, denoting the diameter of the needle in hundredths of a millimeter (0.80 mm, 1.00 mm). The second number (12, 16) is the American standard. The larger the number, the thicker the needle and for denser tissues it is intended. Using a thin needle on a tight jean will cause it to bend or break, and a thick needle on a thin silk will leave ugly holes and can damage the fibers.

For proper selection, it is necessary to correlate the needle number with the thickness of the thread and the density of the fabric. There is no universal rule for all occasions, but there are optimal ranges, compliance with which guarantees a quality line. Needle's eye It should be chosen so that the thread enters it freely, but does not hang, otherwise the tension of the upper thread will be broken.

The golden rule: the diameter of the needle should be the minimum possible for a given tissue so as not to damage it, but large enough not to bend when punctured.

Below is a table of correspondence of needle sizes to tissue types:

Size (EU/US)	tissue	Recommended thread	Point type
60/8 – 70/10	Thin silk, chiffon, organza	№ 50-60	Sharp (Sharp)
80/12	Cotton, linen, costume fabric.	№ 40-50	Universal.
90/14	Tight cotton, drape, thin skin	№ 30-40	Universal/Leather
100/16 – 110/18	Jeans, coat cloth, tarp	№ 20-30	Sharp/Jeans
120/19	Very dense technical fabrics	№ 10-20	Sharp.

Specialized types of points

In addition to size, a critical parameter is the shape of the tip. The standard universal needle has a slightly rounded tip that gently pushes the fabric strands apart without tearing them. However, specific materials require specialized solutions. For example, needles with marking are used to sew knitwear, jersey or elastic fabrics. Stretch or Jersey. Their tip is ball shaped, which allows the needle to pass between the knitted fibers without piercing or cutting them, which prevents the formation of puffs.

Needles with markings are used to work with skin, suede and vinyl. Leather. Their tip is shaped like a blade (trihedral), which makes a clean cut necessary for the thick thread to pass through the dense material. Attempting to sew the skin with a universal needle will lead to the fact that the material simply doubts under the foot, and the line will be uneven. There are needles for denim fabric Jeans with a reinforced rod and a very sharp tip, capable of piercing several layers of dense denim without deformation.

Microscopic damage

Even if the needle seems intact, after 8 hours of operation, its tip will blunt at the micro level. This leads to puffs on thin synthetic tissues. Change the needle more often than you think necessary.

The effect of the needle on the quality of the line

Many of the problems that users attribute to sewing machine malfunctions are actually solved by simply replacing the needle. If the top thread is constantly torn, check if the needle's ears are too small for the chosen thread thickness. When sewing a thick thread through a small ear, friction occurs, the thread heats up and bursts. Conversely, if the thread is thin and the ear is large, the thread will “walk”, which will lead to a loop from below and poor quality of the line.

Passages of stitches often occur when the shape of the tip does not match the structure of the tissue. On knitwear, a universal needle can repel elastic fibers without entering the fabric at the right time. In this case, it helps to install a specialized knitted needle. It is also important to make sure that the needle is placed on the correct side: the flat side of the bulb should look towards the direction indicated in the instruction (usually back or right).

⚠️ Warning: If you hear a knock or click when you lower the needle, stop immediately. This may mean that the needle has bent and touches the foot or needle plate. Continuing to work will cause the shuttle to break.

Replacement frequency and signs of wear

Needles are consumables and their resource is limited. Dull point not only spoils the appearance of the product, but also creates an extra load on the engine of the machine. Professional seamstresses recommend changing the needle after each new project or after 8-10 hours of continuous work. For materials such as leather or tight jeans, it is advisable to change the needle even more often – for example, after each product, since dulling occurs faster.

How do you know if it’s time to throw the needle away?

• 🧵 The thread began to constantly break or fluff at the puncture site.
• 🔊 There was a knock when the needle driver was lowered.
• 👕 On the fabric appeared visible puffs or "tracks".
• 📉 The quality of the line (spinning, jumping) deteriorated.
• 🔍 Visual examination under the magnifying glass shows denting or blunting.

The use of a dulled needle is economically inexpedient, since the cost of one needle is incomparable with the risk of spoiling expensive fabric or damaging the mechanism of the machine.

Brands and compatibility

There are many needle manufacturers on the market, and not all of them are interchangeable. Market leaders are German companies. Schmetz and Organ (Japan). Needles Schmetz Color-labeled bulbs are the standard for many household machines. But the brand's machines Singer Needles with a slightly misaligned ear or a specific bulb shape are often required, although modern Singer models are common with standard 130/705H needles.

Machines. Brother, Janome, AstraLux and Pfaff In most cases, they work with standard 130/705H system needles. It is important to avoid buying cheap needle sets without specifying the manufacturer and system, as the quality of steel in them is often low. Such needles quickly blunt, bend and can break inside the mechanism, which will require expensive repairs.

FAQ: Frequently Asked Questions

Can I use a sewing machine needle manually?

Technically possible, but uncomfortable. Machine needles are shorter than hand needles and have a specific bulb shape, making their grip less comfortable for hand work. In addition, the machine needle eye is often higher than the hand needle, which changes the dynamics of thread stretching.

Why does the needle break when sewing?

Main reasons: the needle is not mounted to the point, a too thin needle for dense tissue is chosen, the fabric is too tightly pulled with your hands (you need to help slightly), or the needle stumbled on a pin / button. The cause may also be the curvature of the needle driver.

What do the colored dots on Schmetz needles mean?

The color marking on the bulb indicates the type and size of the needle. For example, the yellow stripe means a knitted needle (Stretch), blue - for jeans (Jeans), red - for leather (Leather). This allows you to quickly visually determine the purpose of the needle.

How to insert the needle: flat side forward or backward?

In most household machines (Janome, Brother, Pfaff), the flat side of the bulb is directed backwards. In Singer machines, the flat side often heads to the right. Always look for the exact information in the instructions for your particular model, as improper installation will knock the shuttle settings.
