Classification of needles for sewing machines: what are and what is the difference

If you focus on the manufacturer's recommendations, the needle should be changed after 12 hours of sewing. But this - the replacement rule of similar needles. If the same machine is used for different materials, it should be replaced needles in strict compliance with the treated tissue. Only in this way will be able to dispense with marriage breakdowns and unpleasant.

How to choose

The instructions to the user identifies the main characteristics of the needles, which can be operated sewing machine. The easiest way to make the right purchase - prescribe the necessary labeling and focus on it. If for some reason this is not an option, it is necessary to emphasize the shape of the bulb and the tip, stem thickness and size of the ear.

For household sewing machines

For such technique is characterized flask flattened (spilite). This is done for the convenience of users - so facilitated the correct connection of the needle when it is replaced. You can distinguish them by labeling:

• universal - 130/705, HAx1;
• overlock: EL × 705, HA × 1 SP, DC × 1, DB × 1.

Universal used as household sewing machines and overlocking on similar. But if the marking indicates "specialization", then use a needle on another type of prohibited devices.

By industry

The main distinguishing feature - a round bottom flask. Depending on the intended release:

• overlock - DC × 27;
• for lockstitch - DP × 5, 134.

It is necessary to choose a needle in strict accordance with the manufacturer's recommendations. Invalid matched flask leads to a number of problems associated with incorrect operating position of the tip of the tab and with respect to the shuttle.

Meaning of letters

Following the bulb marking letters indicate for what types of materials and works designed needle:

• H - slightly rounded tip, universal ,;
• H-J (jeans) - sharp, dense materials;
• H-M (microtex), SPI - very sharp, fine-fibrous tissue;
• H-S (stretch), SKL, SKF - spearhead circular, elastic synthetic and natural materials;
• H-E (embroidery) - slightly rounded and spearhead special recess decorative embroidery;
• H-EM - wide ear for the metallized thread;
• H-Q (quilting) - decorative stitch punctures without visible;
• H-SUK (jersey), SES - spherical spearhead, and to knitwear knitted materials;
• H-LR, H-LL (leder leather) - cutting edge, the skin;
• H-O - needle with the blade (one or two), decorative seams, with emphasis on the holes;
• H-ZWI, H-DRI - double and triple respectively decorative finish;
• Topstitch - to work with loose decorative thread.

Meaning of digits

After marking the destination number is (he same diameter) needles. It is denoted by a two-digit or three-digit number. Distinguish metric:

• European - hundredths of a millimeter;
• US - the same in inches.

Typically, manufacturers specify the needle number, taking into account both standards. For example: 80/12 (rod diameter of 0.8 mm / 0.12 inches). For double or triple needle indicates one more size - the distance between the axes of the rods. The marking takes the form of 2.5 / 80.

Kinds of needles for sewing machines

Thanks to advances in technology are constantly emerging new types of fabric, at work with which need the special structure of the tip, the ear, and even web. Otherwise, on a flat and solid line will remain only a dream.

knitwear

When working with such material it is important to maintain the integrity of the fibers. Consequently, it is recommended to choose a needle with a spherical tip that will push and not to pierce the fabric yarns. H-S, H-SUK, H-SES - optimum for jersey embodiments. When working with them will be able to form a beautiful line without breaking the strength of the fabric. And it warns the appearance of unsightly "shooter", diverging on the product of the joint.

for the skin

This material must be cut through, as it deforms and breaks the classical piercing. Result - openings of irregular shape and frequent needle breakage. Therefore, you must use tools with a cutting edge. In the application of H-LR, H-LL seam obtained with a slight tilt to the right or left stitch.

For denim

This material requires a thin and strong needle with a slightly rounded tip. But even properly selected tool at the intersection of the seams of denim deviates from the axis, which leads to breakage or skipped stitches. To avoid such troubles needle rod is complemented by a cross-section of the groove.

For the finishing line

This type of work often involves the use of low-strength decorative threads. Eliminate them or break "razmohnachivanie" makes the special structure of the large eye and a special groove along the rod.

Twin needle

Without it, it is impossible to perform double stitching finish. True and apply such a tool will be possible only on machines provided with a zigzag mode, since the rod 2 on one base require a slit in the needle plate. Dual needle worthy place in the arsenal of embroidery, as when using colored upper threads allow to obtain interesting shadow effect.

With wings

May have one or two blades, designed for decorative holes along the seam line. Wings pushing the strands, forming a hole. Often used as a double needle bars.

self-priming needle

This option is also called "easily vdevaemoy". A characteristic feature - leading to lug a small slit through which to thread simply hold it over the bar in the direction of the tip. Due to the low strength of such a needle is only used when working with average density lungs tissues.
