The # 9116 Titanium assortment (75/11, 80/12, 90/14) features needles that have a type of coating applied to the standard steel needle.This coating is done through a very advanced electro-galvanization process which allows the Titanium nitride to be permanently attached to the needle. This coating increases the wear resistance on the needle. A second advantage to the Titanium nitride needle is its anti-adhesion properties. Much like using a non-stick pan for cooking, the Titanium needles resist residue from textile products like sticky back stabilizers and spray adhesives from being attached to and diminishing the performance of the needle. Five (5) needles total. These are top quality sewing machine needles made by Organ needle Co.,LTD.
