Introduction: A 150cm roll width shapes how interlining pieces fit a marker, how much edge trim appears, and how a cutting room organizes the work.
Most people meet this question at the cutting table rather than in a specification sheet. A roll of water jet interlining arrives at a fixed width, a marker is drawn to a certain width, and the gap between those two numbers decides how much usable material comes off every ply. Seeing that relationship clearly makes it easier to understand why one garment style cuts cleanly on a 150cm roll while another leaves a long strip of waste running down the edge of the spread.
Roll width is one of the few variables in garment production that is settled before anyone sharpens a blade. The mill sets the width, the pattern room draws to it, and the cutting room works inside it. On a woven base interlining, that width becomes the outer boundary of every ply in the spread, so it decides how many collar stands, cuffs, or plackets can sit side by side in one row. This matters more for interlining than for many other trims because interlining is usually the layer that has to follow the shell fabric exactly. If the shell is cut from a 150cm marker, an interlining supplied at 60 inches / 150cm gives the layout team a very similar working canvas, which keeps both materials aligned in the same spread or in parallel spreads. The Bai Yu Textile specification for Article 10013 lists a 60 inch / 150cm width, a 70gsm total weight built from a 60gsm polyester woven base and a 10gsm PA coating. The width is the part the cutting table feels first; the weight and coating matter later, at the fusing machine. It is also worth separating width from quality. A wide roll is not automatically better than a narrow one, and a narrow roll is not automatically cheaper in use. What the cutting room actually experiences is the fit between the marker it wants to draw and the roll it has on the rack. A fixed industrial width gives pattern rooms a predictable starting point rather than a moving target.
Marker planning is where width stops being a label number and becomes a practical constraint. The marker is the drawn arrangement of pattern pieces the cutter follows, and its width has to sit inside the roll width with a small allowance for the selvedge and for trimming. When the marker is comfortably narrower than the roll, the leftover strip runs down one or both edges. When the marker is close to the roll width, that strip shrinks to a thin trim line. Interlining pieces are usually smaller than the garment panels they support. Collars, cuffs, plackets, and pocket reinforcements are short, narrow shapes, and a 150cm width lets a pattern room place many of them across a single row. That is the practical appeal of a 60 inch roll for this material: it offers enough horizontal room for a dense arrangement of small parts without forcing the layout team into an awkward stacking pattern. A narrower roll would push the same parts into more rows and therefore into more marker length, which then has to be matched by more plies or more spreads. The other half of marker planning is matching. A garment factory usually wants interlining cut on a marker that echoes the shell fabric marker, because the two layers are joined later by fusing and the pieces must correspond in shape and position. When the shell fabric is a 150cm woven and the interlining is also 150cm, both layouts can be planned on comparable terms, and sizes and colours can be grouped the same way for both. Where the shell is much wider or much narrower, the interlining marker becomes its own separate exercise with its own nesting logic. A 150cm roll suits markers drawn close to 150cm; a marker drawn to 120cm leaves a fixed strip of waste, and a marker that needs 155cm will not fit. Actual utilization depends on the garment size range, how the pattern room nests the pieces, and how the cutting room organizes its spreads and plies.
These three ideas explain almost everything a newcomer notices on an interlining cutting table. They are also the vocabulary a pattern room uses when it decides whether a roll width is helping or hurting a particular style, and they work together rather than in isolation.
Edge waste is the material left outside the marker but inside the roll, and it is easy to spot: a long, narrow band running the full length of the spread. Its size is set almost entirely by the difference between the two widths, plus the selvedge that cannot be used. A cutting-table observer watching a 150cm roll meet a marker drawn to 146cm sees a thin trim strip. The same roll meeting a marker drawn to 130cm shows a much wider band that accumulates over every ply and every layer. That band is a planning outcome, not a defect in the interlining. Factories reduce it by adjusting the marker rather than the material: dropping a small part into the leftover strip, nudging a piece to shift the boundary, or grading sizes so the widest part of the marker lines up with the roll edge. Where a 150cm roll is paired with markers designed around similar widths, the narrow offcuts stay small. Where a wide roll meets a narrow marker, the extra trim is simply part of that layout.
The 60gsm polyester base in Article 10013 is a woven fabric, so it has a lengthwise direction set by the warp, and that direction has to line up with the grain line drawn on each pattern piece. On an interlining marker this usually means pieces cannot be freely rotated. A collar stand placed across the grain behaves differently from one placed along it, and it no longer corresponds to the shell piece it supports. Grain rules are what stop a cutting room from filling an empty corner of the marker with any shape that happens to fit there. Piece grouping works alongside grain direction. Cutting rooms group plies and sizes so a marker covers one consistent set of parts, and they keep colour lots together so off-white, black, and optical white are not mixed inside a spread. A 150cm width gives more freedom in how those groups are arranged across the roll, while grain lines stay parallel and each size group stays intact. Roll length and packing should be confirmed at order stage.
Roll width is a simple number with a long reach. On a 150cm roll, the cutting room gets a working canvas that suits markers drawn to a similar width, which is why a 60 inch interlining often lines up neatly with 150cm shell fabrics and with the small, repeated parts used for collars, cuffs, and plackets. Edge waste, grain direction, and piece grouping then decide how much of that canvas actually turns into garment parts. The useful habit is to think in pairs: roll width against marker width, and interlining marker against shell marker. The practical detail to check is how the 60 inch width lines up with the markers a factory already runs.
A: It means the marker has to be drawn inside 150cm, minus a small allowance for the selvedge and trimming. Small interlining parts such as collars, cuffs, and plackets can be nested many across a single row, and a marker drawn close to 150cm leaves only a thin trim strip, while a much narrower marker leaves a wider band of edge waste.
A: Waste shrinks when the marker width sits close to the roll width. Garments built from many small interlining parts, cut on markers drawn near 60 inches, can place those parts densely across the roll, so the leftover band at the edge stays narrow and the marker needs less length. Styles with large panels or very small size ranges gain less from the same width.
A: Roll width sets the boundary, while utilization comes from the size range, how the pattern room nests the pieces, grain constraints that limit rotation, how plies and colours are grouped, and the habits of the cutting room. A 150cm roll helps when the marker is planned around it and helps much less when the marker is drawn to a very different width.
