Top-Stitch needles can sew material like Vinyl,PU & PVC. This needle is suitable for quilting seams with thicker threads. It can also be used for the sewing of button holes, for decorative stitches with thicker threads and for repair embroidery. This needle has a larger and longer needle eye. The groove is wider in relation to the thickness of the needle and the distance from eye to butt is shorter compared to UNIVERSAL needles. Titanium-nitride is very tough substance and has excellent abrasion resistance which make the needle longer life. Topstitch needles have a larger eye than other needle styles. It is nearly twice as long as the eye on a Universal needle. This extra space allows the thread to have more space to move, which reduces friction and results in fewer thread breaks. There is also a deeper and wider groove on Topstitch needle. This helps keep thread close to the needle and reduces friction from rubbing against the fabric. The strength is increased by high hardness, in combination with perfect durability and excellent anti-abrasion resistance.
