This page explains which spreading and cutting method a cutting room chooses for a given fabric, and which quality fault the wrong choice risks: for a cutting-room supervisor, a quality inspector, or a new entrant learning how cutting decisions are made. This lesson mainly teaches a decision: given a fabric's own properties, which ply height and which spreading method actually suit it.
At work, a cutting room does not spread and cut every fabric the same way. Order A's single-jersey knit and Order B's denim behave differently under the same lay height and the same spreading method, because a knit distorts more easily under tension and layer weight than a stable woven does. A cutting-room team that applies one factory-wide habit to every fabric, instead of matching the method to the fabric in front of it, risks cutting faults found only after the lay is already cut apart.
Without knowing which fault each choice risks, a supervisor cannot judge whether a time-saving shortcut is actually safe. This lesson names the choices a cutting room makes, and the fault each risks when it does not match the fabric.
You need: T07-C02-L01, since fabric relaxation, spreading, lay and ply height are already defined there and reused here. The previous lesson on how a marker is made is useful background, since a lay is spread to match an already-made marker.
By the end of this lesson you can:
Not covered here: fabric relaxation and lay height themselves, first defined in T07-C02-L01; how a marker is made and fabric utilisation, covered in the previous lesson; the full cutting-room quality inspection, including bundling and cut-piece accuracy (T07-C02-L04 and T07-C02-L05).
| Term | Meaning |
|---|---|
| Fabric relaxation | Letting a fabric roll rest flat, unrolled, before spreading and cutting so it settles back from the tension put into it during knitting, weaving or finishing. |
| Spreading | Laying multiple plies of fabric on top of each other on the cutting table to build the lay the marker is then cut through in one pass. |
| Lay (spread) | The full stack of fabric plies built up by spreading, on which the marker is placed and through which the cutter cuts in one pass. |
| Ply height (lay height) | The number of layers stacked in a lay, or the physical height this stack reaches; a cutting order sets a maximum for a given fabric and blade. |
| Cut-piece matching | Checking that cut pieces meant to be sewn together match each other in shade, pattern placement or grain, not only in size, before they are bundled for sewing. |
| Bundling | Sorting cut pieces from a lay into tied bundles, each holding the matching pieces needed to sew one style, size and colour together, ready to move to sewing. |
Spreading and cutting method choices are driven by the fabric in front of the cutting room, not fixed for every order. Order A's single-jersey knit needs more care in relaxation time and a more controlled ply height than Order B's stable denim, because a knit distorts more easily under tension and layer weight than a woven does. Too high a ply height for a given fabric and blade risks inaccurate cuts through the lower plies of the lay, since the cutter loses precision as the stack gets taller. Face-to-face spreading of a one-way-nap or one-way-print fabric risks producing mirror-image, wrong-facing pieces if the fabric's direction is not tracked ply by ply. A cutting room's method choice must match the fabric's own properties, confirmed before spreading begins, never applied the same way to every fabric that reaches the table.
| What can differ | The shapes you meet | Why it matters |
|---|---|---|
| Controlled ply height for the fabric and blade | The lay stays within the maximum ply height stated in the cutting order for that specific fabric and cutting equipment | Keeps cut accuracy consistent through every ply, the goal every lay works towards |
| Excess ply height | A taller lay than the cutting order allows, common under delivery-date pressure to cut more per pass | Risks inaccurate cuts through the lower plies, the lay height check point T07-C02-L04 inspects for |
| Face-up spreading | Every ply laid the same face up, tracking direction consistently, used for directional or one-way fabrics | Slower to spread, but avoids mirror-image pieces on a one-way-nap or one-way-print fabric |
| Face-to-face spreading | Plies alternated face up and face down for speed, used for non-directional fabrics | Faster, but only safe when the fabric has no one-way nap, print or pile to track |
| Cut-piece direction tracking | Whether a directional fabric's ply-by-ply orientation is tracked and later checked at cut-piece matching | An untracked direction on a directional fabric turns into a cut-piece matching fault once bundling begins |
Delta Garments' cutting room illustrates the contrast this lesson teaches. Order A's single-jersey knit needs a shorter, carefully controlled lay because of its stretch, and a longer relaxation time before spreading begins. Order B's denim, a stable woven, tolerates a taller, sturdier lay and needs less relaxation time. Neither order fixes an exact ply-height figure in this academy's master cast, so Karim, Delta Garments' production manager, confirms the method against each fabric's own properties before spreading starts, rather than against one factory-wide habit.
No new fixed ply-height figure is introduced here. To illustrate the risk, suppose a cutting order sets a maximum of 60 plies for Order A's knit fabric and blade, and a maximum of 100 plies for Order B's denim and blade. These two numbers are illustrative examples only, not new facts about Delta Garments or Order A/B fixed elsewhere in this academy.
| Order | Illustrative maximum ply height | Spread at this height | Spread 20 plies above this height |
|---|---|---|---|
| Order A (knit) | 60 plies (illustrative) | Cut accuracy consistent through every ply | Inaccurate cuts risked through the lower plies |
| Order B (denim) | 100 plies (illustrative) | Cut accuracy consistent through every ply | Inaccurate cuts risked through the lower plies |
A cutting room that copies Order B's own illustrative 100-ply maximum onto Order A's knit, to cut more pieces per pass, spreads 40 plies above the knit's own illustrative maximum, risking inaccurate cuts through the lower plies of that lay.
The methodA common mistake is applying one factory-wide "standard" ply height or spreading method to every fabric, regardless of that fabric's own properties. A ply height and spreading method that work safely for Order B's stable denim can produce real cutting faults if applied unchanged to Order A's stretchier knit. This trap is easy to fall into under delivery-date pressure, when a cutting-room team wants to cut more pieces per pass to make up lost time. But the fabric's own properties, not the delivery date, decide which ply height and spreading method are actually safe; a faster lay that produces faulty cut pieces costs more time to catch and re-cut than the spreading time it saved.
Not every fabric can be cut the same way. A stretchy T-shirt fabric moves and pulls out of shape more easily than a sturdy denim, so it needs a shorter stack of layers on the cutting table, and more resting time before cutting starts. Stacking layers too high for a given fabric means the cutter loses accuracy through the layers near the bottom of the stack. Laying every layer the same way up, instead of flipping every other one, takes longer but is the only safe choice for a fabric with a one-way pattern or a one-way nap, since flipping such a fabric produces pieces that face the wrong way. A cutting room checks the fabric in front of it first, then decides the stack height and the laying method, instead of using the same habit for every fabric that reaches the table.
The facts in front of the cutting-room team:
The note the supervisor reads, from the team's own shift plan:
Is this a safe way to make up time? Decide before you open the answer.
No. Order A's single-jersey knit is more prone to distortion under layer weight and tension than Order B's stable woven denim; applying denim's taller ply height to the knit risks inaccurate cuts through the lower plies of the lay.
Two facts, together, decide this. First, the general rule: too high a ply height for a given fabric and blade risks inaccurate cuts through the lower plies, since the cutter loses precision as the stack gets taller. Second, the fabric fact: Order A's knit distorts more easily under tension and layer weight than Order B's denim, so a ply height that is safe for denim is not automatically safe for the knit.
The faulty pieces this produces cost more time to catch and re-cut than the spreading time the team was trying to save, so the shortcut does not actually make up the lost time; it risks losing more of it.
This is framed qualitatively, since no separate cost figure for a mismatched ply height or spreading method is fixed elsewhere in this academy. Mismatching a spreading or cutting method to the fabric, whether excess ply height or face-to-face spreading of a directional fabric, risks a batch of faulty cut pieces discovered only after cutting, once the lay is already cut apart and the fault can no longer be prevented at the spreading stage.
A faulty batch found after cutting needs rework or re-cutting from fresh fabric, both costing more time than the spreading time a taller, faster lay was meant to save. The real cost is however many pieces from that lay need re-cutting once the fault is found, plus the time spent finding which pieces are affected. This check is designed to catch a fabric-method mismatch before spreading, when it costs only a supervisor's confirmation, rather than after cutting, when it costs rework.

1. Why does Order A's knit fabric need more care in ply height than Order B's woven denim?
2. What quality fault does spreading face-to-face risk on a one-way-nap or one-way-print fabric?
3. A different fabric's cutting order sets a maximum of 80 plies for its own fabric and blade. The cutting room spreads it at 95 plies to save time. What fault does this risk?

|---|---|---|---|---|
| Fabric relaxation | استرخاء القماش | Détente du tissu (relaxation) | Kumaş dinlendirme (relaksasyon) | Letting a fabric roll rest flat, unrolled, before spreading and cutting so it can settle back from the tension and distortion put into it during knitting, weaving or finishing; cutting a fabric that has not relaxed risks cut pieces shrinking or distorting out of spec after cutting. |
| Spreading | فرد القماش | Étalement du tissu (matelassage) | Kumaş serimi | Laying multiple layers (plies) of fabric on top of each other on the cutting table, one on top of the next, to build the lay that the marker is then cut through in a single pass. |
| Lay (spread) | الفرشة (اللاي) | Matelas (nappe de tissu) | Kumaş serisi (lay) | The full stack of fabric plies built up by spreading, on which the marker is placed and through which the cutter cuts in one pass. |
| Ply height (lay height) | ارتفاع الفرشة (عدد الطبقات) | Hauteur du matelas (nombre de plis) | Kat yüksekliği (seri yüksekliği) | The number of fabric layers stacked in a lay, or the physical height this stack reaches; a cutting order sets a maximum ply height for a given fabric and blade because too high a lay risks inaccurate cutting through the lower plies. |
| Cut-piece matching | مطابقة القطع المقصوصة | Appairage des pièces coupées | Kesilen parça eşleştirme | Checking that cut pieces meant to be sewn together (for example a garment's two front panels, or a striped fabric's pieces across a seam) match each other in shade, pattern placement or grain, not only in size, before they are bundled for sewing. |
