SCHMETZ NIT Needles

Special anti-adhesive coating with excellent gliding properties

To protect industrial sewing machine needles against corrosion they are coated with hard chrome, but also to provide a better glidability, as this coating reduces friction during the sewing process. For standard requirements, this conventional coating is more than sufficient. Challenging sewing processes sometimes require the use of needles with a special coating, for instance in the processing of abrasive materials or fabrics with a high man-made fiber content.

Abrasion and high sewing speeds generate high needle temperatures. There are a few ways to keep the temperature down. Still, in some occasions, melted synthetic material sticks to the needles surface clogging the long groove and the needle´s eye disturbing the sewing process or even damaging material and thread.

NIT–coating is a solution to many of these situations.

Advantages:

• Prevents the adhesion of melted residues on the needle even when sewing critical materials, therefore the needle stays clean for longer
• Nearly 20% better glidability of the thread through the eye of a NIT coated needle:
• Easy sliding of sewing thread through needle eye allowing the use of very thick sewing threads possible
• Easy penetration of hard materials due to outstanding low-friction properties of the surface
• Optimum thread protection
• Avoids thread breakage
• Less skip stitches
• More continuity in the sewing process due to reduced downtime

Application:

• Materials with a low softening/melting point
• Man-made materials
• Materials with a high man-made fibre content
• Materials with special finishing, e.g. flame retardant, color, modifications of textile threads or surfaces as regards wear and care properties
• Heavy and hard materials
• Coated materials
• In case of needle and eye smearing when using standard chrome plated needles
