Bowing
Fabric distortion causing the weft to not be at right angles with warp. Prevent by controlling tension and improving fabric construction.
Oil Stains
Stains from machinery oils. Prevent by regular equipment cleaning and using oil guards.
Pilling
Formation of small balls of fiber on fabric surface. Prevent by selecting pill-resistant fibers and optimizing weaving/knitting settings.
Wrinkling
Unwanted creases caused by improper finishing or storage. Prevent by controlled finishing processes and correct folding techniques.
Shading
Color variations within the same piece of fabric. Prevent by ensuring dye lot consistency and thorough mixing.
Skewness
Distortion causing fabric sides to not be parallel. Prevent by controlling fabric tension and proper machinery setup.
Abrasion Marks
Caused by excessive friction during processing. Prevent by ensuring proper lubrication and material handling.
Yarn Variance
Inconsistent yarn diameter. Prevent by ensuring uniform spinning and material handling.
Color Out
Dyeing defect causing uneven color. Prevent by using quality dyes and consistent dyeing processes.
Fabric Run
Laddering defect caused by weak yarns or snagging. Prevent by using stronger yarns and protective packaging.
Drop Stitch
A knitting defect where a stitch is not properly formed. Prevent with machine calibration and operator training.
Slubs
Thicker places in yarn creating a lump. Prevent by using quality spun yarns and effective quality control.
Grinning
Shows the warp through widely spaced weft. Prevent by ensuring proper fabric density and tension balance.
Holes
Caused by mechanical damage or weak spots in yarns. Prevent with material inspection and gentle handling.
Broken Pick
Missing horizontal yarn due to loom malfunction. Prevent by regular machine maintenance and quality checks.
