Thread Structure

The type of yarn structures used in producing sewing thread are
• Spun yarns
• Filament
• Core spun

Twist

It is the number of turns per centimeter of thread.
If twist is too low ,threads may fray and break.
If it’s too high ,thread becomes “lively” which results in looping or knots and that will not allow the stitch formation
