Many fabric faults are born in the yarn. Knowing which ones helps you specify better and avoid costly seconds.
Barre and streakiness
Uneven yarn (high CV%), mixed lots or count variation show as horizontal bars in knits and streaks in wovens. Consistent count and evenness batch to batch are the fix.
Neps and specks
Neps — tiny fibre knots — show as specks, especially in fine or dyed fabric. Combed cotton has far fewer neps than carded.
Shade variation
Inconsistent blends or dyeing cause patchy colour. Blends batched for even fibre distribution and shade-matched dyed yarn keep colour consistent.
Contamination
Stray coloured fibres or trash cause visible defects — clean handling and storage help; see storing yarn.
The common thread
Consistency prevents faults. That is exactly what our quality standards are built around.
