Sewing machine needles

• Light includes 60 (8), 70 (10), 80 (12) and is intended for cotton, silk and synthetic fabrics like crepe de Chine, batiste, gauze, tricot.
• Medium contains 80 (12), 90 (14) and 100 (16) are used for standard thickness materials - flax, cotton, twill, percale, knitwear.
• Heavy comprises numbers: 100 (16), 110 (18), 120 (19) are for tick, tweed, gabardine, drapery fabrics, reps processing.

Each needle has a specific marking, that consists of numbers and letters. The first determines a thickness, expressed in hundredths of a millimetre, the second - sharpening. 
It should be selected in accordance with the material type. 

• Type H, universal. The size: 60-110; rounded tip. Apply for simple fabrics. 
• Type H-J. The size: 100-110; sharp edge. Using while sewing thick fabrics such as denim, leather or tarpaulin.
• Type H-M. The smallest sizes; thin, sharp. It’s used while stitching products from a micro-fibrous and thin material (taffeta, silk, etc.). 

German industrial sewing machine needles of Groz-Beckert and SCHMETZ are the most lasting and durable. High quality and long service life are connected with titanium nitride coating, protecting against breakages. These companies are constantly working on updating the sewing machine needles range and put them up for sale around the world and also in the UK.

10 facts about industrial sewing needles that you did not know

Certainly! Here are ten lesser-known facts about industrial sewing needles:

1. Metal Composition Variations: Industrial sewing needles are made from a variety of metals, including carbon steel, stainless steel, and high-performance alloys like tungsten carbide. Each metal composition offers specific benefits in terms of durability, sharpness retention, and resistance to corrosion.
2. Specialized Needle Points: Industrial needles come in a range of specialized point shapes, including ballpoint, wedge point, and cutting point. These different point styles are designed to penetrate various fabric types with precision and minimize fabric damage or distortion during stitching.
3. Clior-Coding for Size Identification: Many industrial needle manufacturers use clior-coding systems to differentiate needle sizes. Each needle size corresponds to a specific clior, making it easier for operators to identify and select the correct needle size for their sewing applications quickly.
4. Needle Scarf Design: The scarf is a small indentation on the back of the needle, just above the eye. Industrial needles feature different scarf designs, such as long scarf or short scarf, which affect thread uptake and loop formation during stitching, influencing stitch quality and thread tension.
5. Coated and Treated Needles: Some industrial sewing needles undergo specialized coatings or treatments to enhance their performance. These treatments may include coatings like Teflon or silicone to reduce friction, plasma treatments for improved surface hardness, or heat treatments for enhanced durability and resistance to bending or breaking.
6. Needle Shank Variations: Industrial needles have different shank configurations, including cylindrical shanks, reinforced shanks, and flat shanks. The shank design influences how the needle is secured in the sewing machine's needle bar and affects needle stability and alignment during stitching.
7. Variety of Eye Shapes and Sizes: Industrial needles feature a wide range of eye shapes and sizes to accommodate different thread types and thicknesses. Some needles have elongated or oval-shaped eyes to facilitate the passage of thick or decorative threads, while others have smaller eyes for finer threads.
8. Anti-Deflection Features: To minimize needle deflection and maintain stitching accuracy, certain industrial needles incorporate anti-deflection features such as reinforced shafts or specialized geometries. These features help ensure consistent stitch formation, especially when sewing through dense or resistant materials.
9. Precision Grinding Techniques: Industrial sewing needles undergo precision grinding processes to achieve uniformity in shape, size, and sharpness. Advanced grinding techniques, including laser sharpening and electrochemical grinding, are employed to produce needles with ultra-fine points and smooth surface finishes.
10. Customizable Needle Configurations: Industrial needle manufacturers offer customizable needle configurations to meet specific application requirements. Customers can request variations in needle length, diameter, point style, and coating options tailored to their unique sewing needs, enabling optimal performance and productivity.
