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. Titanium nitride is a reflective golden-colored ceramic material which reduces abrasion allowing the needle to stay sharper longer and ...
An inoculation needle is a laboratory equipment used in the field of microbiology to transfer and inoculate living microorganisms. [1] [full citation needed] It is one of the most commonly implicated biological laboratory tools and can be disposable or re-usable. [1] A standard reusable inoculation needle is made from nichrome or platinum wire ...
types of hand sewing stitches. This is a list of stitches used in hand and machine sewing. The most common standard for stitches in the apparel industry is ASTM International ASTM D6193-16(2020) [1] The standard also covers various types of seams. Under this classification of stitches there are basic groups as follows:
A sewing needle. A sewing needle, used for hand-sewing, is a long slender tool with a pointed tip at one end and a hole (or eye) to hold the sewing thread.The earliest needles were made of bone or wood; modern needles are manufactured from high carbon steel wire and are nickel- or 18K gold-plated for corrosion resistance.
Examples include: Backstitch; Overcast stitch; Cross stitch; Buttonhole or blanket stitch; Chain stitch; Knot stitch; These stitches and their variations are named according to the position of the needle and direction of sewing (running stitch, backstitch), the form or shape of the stitch (chain stitch, feather stitch) or the purpose of the stitch (tailor's tack, hem stitch).
Most lockstitch machines made after the 1960s are capable of doing this; older machines achieve the same stitch with a specialist presser foot which moves the fabric beneath the stationary needle. Zigzag stitches are used when a stretchable stitch is required, such as when sewing stretchy fabrics.
Electronic sewing machines incorporate components such as circuit boards, computer chips, and additional motors for independent control of machine functions. These electronic components enabled new features such as automating thread cutters, needle positioning, and back-tacking, as well as digitized stitch patterns and stitch combinations.
The 18th century stands out as a transformative period for notions. The first sewing needle factory opened in Germany in 1730, and the first mechanical needle was manufactured 25 years later. Although no surviving sewing machine from that era has been discovered, the groundwork for such a device was unmistakably laid. [7]
