Titanium nitride on top of chromium is the most expensive and is superior in performance to both chrome and nickel. Chrome plating lasts longer and gives better abrasion resistance. Nickel plating is the least expensive and least durable form of plating. The titanium does not make the needle any stronger in regards to bending, however, and such needles will bend and snap just as easily as any other. Titanium nitride is a reflective golden-colored ceramic material which reduces abrasion allowing the needle to stay sharper longer and last many times longer than other varieties.
The majority of sewing machine needles are made of various grades of hardened steel coated with either nickel or chromium, though certain specialty needles are coated with titanium nitride on top of chromium. The 15x1 needle is available in different standardized shaft diameters suitable for sewing different fabrics (see the section on Size codes below).įor commercial/industrial sewing machines, there are several proprietary sizes and types of needles which are not mentioned in this article. Needles labeled as "universal" needles are of this type and are generally the type of needles found in retail sewing supply shops. point - penetrates the material by either parting the threads or cutting a hole in the fabricĭomestic sewing machines, designed for use in homes as opposed to commercial sewing operations, use a common needle type (including a standardized length, as well as shank shape and diameter) referred to as "Groz-Beckert 130 / 705," "HAx1" or "15x1" needles.scarf - provides extra room for the hook or shuttle to pass close by.groove - cut in the front of the shaft to allow the thread to lie more closely to the needle as it passes through the fabric.
