Defects like dirty equipment, fly, slubs and foreign matters that are considered unacceptable can lead to over 400% increase in defects. Issues like damage to fibers, improper piecing and equipment problems can increase defects by 250-150%. Short thick places caused by issues like damage to fibers and improper piecing can increase defects by 100%. The document further categorizes defects based on their length and describes how problems at different stages of production like spinning, piecing and handling can cause long thin or thick places.
