Incoming Fabric Inspection: What Happens Before Cutting

Most buyers never see this stage and most quality conversations skip it, which is odd, because a meaningful share of garment defects are fabric defects that were allowed through. A cutting room can cut accurately from bad cloth all day. This is the check that decides whether it has to.

Why it happens before cutting

The cost of a fabric fault multiplies at every subsequent operation. A fault found on the roll costs a claim against the mill. The same fault found after spreading has consumed cutting time and turned into panels that may or may not be usable. Found after sewing, it is a finished garment, and the labour is gone whether the garment ships or not.

Incoming inspection is part of the quality-control process. Schedule it early enough to resolve material issues before cutting; a production slot may already have been reserved.

What is checked when the rolls arrive

How faults are graded: the four-point system

The four-point system is one approach to visual fabric grading. ASTM D5430 covers different point-assignment options, so agree the option, defect rules and reporting units before comparing roll scores. The outline below describes a common four-point approach; the agreed method governs the inspection.

• A defect up to 3 inches, about 75 mm, scores 1 point. Over 3 up to 6 inches scores 2, over 6 up to 9 inches scores 3, and anything over 9 inches, about 230 mm, scores 4.
• No more than 4 points can be assigned to any single defect, and no single linear yard can carry more than 4 points however many faults it contains.
• Score holes and openings under the agreed method. Do not assume every hole receives 4 points: some methods distinguish smaller and larger holes.
• A continuous defect running along the roll scores 4 points for every yard in which it appears.
• Points are totalled and expressed per 100 square yards, which makes rolls of different lengths comparable.

Inspection conditions are part of the method rather than a detail: fabric is inspected on a machine under adequate lighting at a controlled speed, because faults missed at speed are faults that reach the cutting table.

Shade: the check that decides how the order is cut

Dyeing is a batch process, so rolls vary. Two things are assessed: whether each roll matches the approved standard, and whether the rolls match one another, including across the width of a single roll, which is why the check is taken at both selvedges and the centre.

Group compatible rolls into shade bands and plan cutting to keep panels within the agreed shade tolerance. Check variation within rolls as well as between them: one roll or band does not by itself guarantee a match. Investigate mismatches against roll records and cutting controls rather than assigning responsibility from the symptom alone. See why fabric shade varies between dye lots.

Testing that belongs at this stage

Select incoming tests according to material risks and the agreed specification before releasing fabric for cutting. Later garment processing can also change performance, so incoming results do not replace any required garment-stage or final-product tests.

• Dimensional stability, tested at the wash the product will actually receive. A fabric outside the agreed limit is a fabric problem, and it becomes a garment problem the moment it is cut.
• Colourfastness, particularly rubbing on dark shades, which is where unfixed surface dye shows up. The tests and how to specify them are in the colourfastness reference.
• Pilling, where the programme has a surface durability requirement, as covered in fabric pilling.
• Weight verification checks mass per unit area against the specification and tolerance; it cannot by itself establish fabric identity or detect every substitution.

Relaxation and skew

Assess the relaxation needed before spreading so that fabric is not cut under unintended tension. Check bow, skew and dimensional stability against the specification; the risk of garment twisting also depends on yarn, construction and processing. Investigate an unacceptable result before cutting rather than assuming it is inevitable or impossible to correct. See the cutting room and why T-shirts twist after washing.

What happens to fabric that fails

Options are limited and all of them cost time, which is the argument for inspecting early rather than thoroughly at the last minute.

1. 1Reject the roll and claim against the mill, which is clean but leaves a quantity gap to fill.
2. 2Accept it at a lower grade for a less critical use, if one exists in the programme.
3. 3Cut around identified faults, which the cutting room can do when faults are marked, at the cost of efficiency and additional fabric.
4. 4Accept it with the buyer's agreement, where the fault is cosmetic and the alternative is missing a date. This should be a documented decision, not a silent one.

What a buyer should specify

Most of these take one line each and remove an entire category of later dispute. How they fit into the wider inspection framework is covered in the quality control guide.

How this works at Voyager Textile

Incoming fabric is checked before cutting for shade continuity across rolls, width, weight and visible faults, and knitted fabric is relaxed before spreading. Where a customer's programme requires a specific grading system, threshold or test regime, that is agreed at specification stage and applied to the order rather than assumed. The production sequence it sits inside is set out on the manufacturing processes hub.
