Needles for industrial sewing machines SCHMETZ DBx1 DH or 1738 DH are needles for technical materials with a DH (Half triangular point) cutting tip. This tip has a semi-triangular cross-section (smaller than the D point), which makes a narrow cut in the material and creates a straight, firm stitch without pulling the material. Ideal for coarse and regular seams, as well as cross-seams on thicker covering materials.

Suitable materials

• Composite materials (for example, laminated materials combined with plastic sections)
• Plastic parts and plastic sections
• Rigid cardboard
• Canvas and tarpaulin materials
• Awning and canopy fabrics
• Other technical covering materials

Where DH particularly excels

• Coarse and regular seams on technical fabrics and coverings
• Cross-seams and joins where material thickness changes
• Automotive interior trim, seats, panels
• Sewing tarpaulins, tents and canopies

DH (Half triangular point) advantages

• Narrower cut than the classic D point less material damage
• Clean, straight penetration even in thick covering materials
• Stable stitching without pronounced needle deflection
• Especially suitable for technical, structural seams, not just decorative effect

Thread recommendations for technical materials

Indicative recommendations when choosing thread and needle for the DH point:

• For regular seams (automotive interior trim, upholstery, rigid cardboard): polyester tex 4075 (approximately No. 40) with needle NM 110

Always advisable to test the exact combination on the specific material.
