FABRICATION
(Knitting, Weaving)
What is a Fabric Defect?
A
Fabric Defect is any abnormality in the Fabric that hinders its Acceptability
by the consumer
WHAT ARE THE FACTORS THAT COULD LEAD TO FABRIC DEFECTS?
Machine-Related Factors:
• Failure of spinning preparation to eliminate or minimize short and long-term variation
• Failure of spinning preparation to eliminate or minimize short and long-term variation
• Failure of opening and cleaning machines to
completely eliminate contaminants and trash particles
• Failure of the mixing machinery to provide a
homogeneous blend
• Failure of the mixing machinery to provide a
homogeneous blend
• Excessive machine stops particularly during pinning
• Excessive ends piecing during spinning preparation
• Poor maintenance and housekeeping
• Weaving-related defects
• Knitting-related defects
• Excessive ends piecing during spinning preparation
• Poor maintenance and housekeeping
• Weaving-related defects
• Knitting-related defects
Material-Related Factors:
• Fiber contaminants
• Excessive naps and seed coat fragments
• Excessive short fiber content
• Excessive trash content
• High variability between and within-mix
• Clusters of unfavorable fiber characteristics
• Weight variation
