Industrial Sewing Machine Needles-SCHMETZ DPx16 LR-135x16 R TW for Leather

SCHMETZ DPx16 LR also known as 135X16 R TW, DPX16 LR are industrial sewing machine needles for leather with LR (Reverse Twist) point. The needle point is cut at an angle of about 45° to the thread direction, so the seam on leather looks decoratively slanted (slight leftward slant) with a clean, distinct cut. Chrome coating reduces friction and heat, ensuring a long service life in high-volume production.

🧵 Suitable materials

• All types of natural and synthetic leather
• Leather combined with textiles (bags, linings, belts)
• Thicker coated materials (e.g., car upholstery, bag components)

✨ Where LR shines

• Decorative/topstitch seams on leather with a sleek, even slant
• Shoe and apparel industry, leather upholstery
• Sewing bags, suitcases, car seats

🎯 Advantages of LR (Reverse Twist)

• Clearly cut stitch without leather fuzzing
• Aesthetically slanted seam – ideal for decoration and visible topstitching
• Stable stitch even with thicker threads

🧶 Thread recommendations for leather

Choose the needle and thread size according to leather thickness and the desired effect (the thicker the material, the larger the NM and thread tex):

• Decorative/topstitching: polyester or polyamide approx. tex 75–150 (No. 20–8) with needle NM 100–160
• For medium-thick leather: polyester approx. tex 50–75 (No. 40–30) with needle NM 110–160
