What Can Go Wrong If You Skip Fabric Relaxing?

Fabric relaxing sounds like a small step, but it protects your whole production line. When fabric is shipped and stored, it gets squeezed and stretched. Even if it looks flat, it can still hold “hidden tension.” If you cut it right away, the fabric may relax later and change size or shape. This is where trouble starts. You can get shrinkage and size drift, twisting seams (especially in knits), grain problems like skew or bow, marker and width mismatch, and then sewing turns into rework and repairs. In this article, you’ll see exactly what can go wrong when you skip fabric relaxing and why a little waiting upfront can save a lot of time and money later.

What Can Go Wrong If You Skip Fabric Relaxing?

Shrinkage and Size Change

When fabric has been rolled and squeezed, it often holds “hidden tension.” If you cut it right away, the fabric may relax later and become slightly shorter or narrower. Then, even if the pattern was correct, the pieces won’t measure the same anymore. That’s how size problems show up later in sewing, ironing, or after washing. Some fabrics “pull back” after they rest. Others change again after ironing or washing. If you cut too early, you may see:

Garment panels measuring short,
Sleeve lengths inconsistent,
Waistbands not matching body panels,
Collars that no longer fit the neckline.

Even a small change can cause big issues when you multiply it across a full size set.

Twisting Seams (especially in knits)

Twisting is a very common issue with knit and stretch fabrics. At first, the panels look fine, but after the fabric relaxes, it can rotate a little. As a result, side seams may swing forward or backward, and legs can twist on pants. Customers notice this fast because the garment feels “off” when worn. Knits often carry more tension than wovens. When that tension releases later, the garment can twist. You’ll notice:

side seams rotating forward/back,
legs twisting on pants,
hems not hanging level.

This is a common reason for customer complaints like: “Why does it always twist after I wash it?”

Skew, Bow, and Grain Problems

Fabric is supposed to sit straight on the grain, but transport and storage can shift it. If the grain is not stable, your cut panels may look slightly slanted even when they seem “flat.” Later, stripes, checks, and prints won’t line up cleanly. This creates a messy look that is hard to fix after cutting. Fabric can look fine when rolled, but the grain may not be balanced. After relaxing, you may see:

stripes or checks drifting,
panels that don’t align,
plackets that lean,
pockets that look “off.”

If the grain is not stable before cutting, it becomes very hard to correct later.

Marker and Width Mismatch

Fabric width can change after it rests, especially with knits and fabrics with stretch. If you build your marker using the “arrival width,” you may lose edge parts during spreading and cutting. That leads to wasted fabric, missing pieces, or last-minute marker changes. So, relaxing helps you plan cutting based on the real working width. A roll under tension can measure wider (or narrower) than it will be after it relaxes. That leads to:

poor marker efficiency,
missing cut parts at the edge,
forced spreading adjustments,
extra fabric waste.

Sewing Issues and Rework

When cut pieces don’t match, sewing becomes a fight. Operators start pulling, stretching, or forcing seams to meet, which causes puckering and shape distortion. Then QC finds more defects, and the line slows down with repairs and recuts. Relaxing fabric early prevents these problems from spreading across the whole production line. When pieces don’t match, you get:

stretching and pulling at sewing,
puckering and bubbling,
mismatched seam lengths,
higher defect rates in inline and final inspection.

And the worst part: it wastes time in the most expensive places cutting and sewing.

Final Words / Conclusion

Fabric relaxing may look like a “small” step, but it protects everything that comes next. When the fabric rests first, your cutting is more accurate, your sewing is smoother, and your sizes stay more consistent. In the long run, it helps you avoid twisting seams, shrink surprises, and costly re-cuts. So, instead of rushing, give the fabric time to settle—because a little patience at the start saves a lot of trouble at the finish.
