Cutting in Garment Manufacturing: Objective, Need and Basic Process
Cutting is one of the most important operations in garment manufacturing. Once the fabric has been checked, relaxed if required, and spread properly, it has to be cut into the required garment components. These components may include the front, back, sleeves, collar, cuff, pocket, waistband, facing, lining and other small parts depending on the garment style.
The cutting room acts as a bridge between the fabric store and the sewing room. If cutting is inaccurate, the sewing department cannot correct the problem easily. A small mistake in cutting may lead to poor garment shape, mismatched parts, size variation, fabric wastage, or rejection of the finished garment. Therefore, cutting is not just a mechanical operation; it is a technical and economic activity.
Objective of the Cutting Room
The main objective of the cutting room is to cut garment parts accurately and economically. Accuracy means that every cut part should match the required pattern shape, size and grain direction. Economy means that the fabric should be used in such a way that wastage is kept as low as possible.
Another important objective is to cut garments in sufficient quantity so that the sewing room receives a continuous supply of work. If the cutting room is slow, sewing operators may remain idle. If the cutting room cuts incorrectly, the sewing room may face fitting problems, mismatched parts, or shortage of components. Thus, the efficiency of the sewing room depends heavily on the planning and performance of the cutting room.
Why Cutting is Necessary
A garment is made from many different pattern shapes, but fabric is supplied in a continuous length and fixed width. Cutting is necessary because a flat fabric has to be converted into shaped garment parts. These parts are later joined together by sewing to create the required three-dimensional garment shape.
Fabric width is also a limitation. A garment pattern cannot always be made from one full piece of cloth without joints. For example, shirts, trousers, dresses and jackets require several separate components because the human body has curves, movement points and fitting requirements. Cutting helps in arranging these parts within the available fabric width.
Cutting is also necessary because a fabric wrapped around the body must be joined somewhere. The position of this joint has to be planned carefully. In garments, seams are placed at suitable locations such as the side seam, shoulder seam, armhole, inseam, waistband or center back. These seam positions are decided by design, comfort, fit and production convenience.
Basic Steps in Cutting a Single Garment
When a single garment is to be cut, the paper pattern is placed directly on one or two layers of fabric. The pattern pieces are arranged carefully, keeping in mind fabric grain, design direction, checks, stripes, motifs, nap, shade variation and fabric defects.
After the pattern pieces are positioned, they may be pinned, weighted, traced or marked depending on the fabric and production method. The garment parts are then cut using hand shears, electric cutters or other suitable cutting tools. In small tailoring setups, hand shears are commonly used. In industrial garment manufacturing, electric straight knives, round knives, band knives and automated cutting systems are more common.
Special care is required when the fabric has checks, stripes, borders or large motifs. In such fabrics, careless cutting can disturb the appearance of the garment. For example, if the stripes on the left and right panels do not match, the garment may look defective even if the stitching is technically correct.
Cutting Large Quantities of Garments
In mass production, garments are not cut one by one. Instead, a lay is created. A lay is a stack of fabric plies spread one over another on a cutting table. Each ply represents one garment layer or one part of the production quantity. The number of plies in the lay depends on the order quantity, fabric type, cutting equipment and handling capacity.
On top of the lay, a marker is placed. A marker is a planned arrangement of all pattern pieces required for one or more garment sizes. It is usually prepared on paper or digitally in modern CAD systems. The purpose of the marker is to arrange the pattern pieces in such a way that maximum fabric is utilized and minimum wastage occurs.
Marker planning is a very important activity because fabric is usually the largest cost component in a garment. Even a small improvement in marker efficiency can lead to significant savings in large-volume production. Pattern pieces are interlocked closely wherever possible, but this must be done without disturbing grain direction, design matching, size accuracy or cutting feasibility.
What is a Lay?
A lay consists of many layers of fabric spread evenly on the cutting table. All the layers are usually of the same length as the marker. After spreading, the marker is placed on top and cutting is done through all the layers together. In this way, many identical garment parts can be cut at the same time.
However, increasing the number of plies is not always better. If the lay is too high, cutting accuracy may reduce. The lower plies may shift, edges may become uneven, and small pattern parts may become distorted. Therefore, the height of the lay must be decided carefully based on fabric thickness, fabric slipperiness, cutting machine capacity and the accuracy required.
Simple Cutting Quantity Relationship
\( \text{Number of garment sets cut} = \text{Number of plies} \times \text{Number of complete marker sets} \)
For example, if one marker contains all parts for one complete garment and 50 plies are spread, then 50 garments can be cut from that lay. If the marker contains two complete garment sets and 50 plies are spread, then 100 garments can be cut.
Factors Affecting the Number of Plies in a Lay
The first factor is the order quantity. If the order is large, more plies may be spread so that a higher number of garments can be cut in one operation. This increases productivity and reduces handling time.
The second factor is material availability. Sometimes the fabric available may not be sufficient to create a very large lay. In such cases, the cutting plan has to be adjusted according to the available fabric length, shade lots and production priority.
The third factor is the physical capacity of the cutting equipment. Every cutting tool has a limit. Hand shears can cut only a few layers. A straight knife can cut more layers, but only up to a certain lay height. Automatic cutters also have technical limits depending on blade movement, vacuum control and fabric compression.
Fabric characteristics also influence lay height. Thin and stable fabrics can often be cut in higher lays. Thick, slippery, stretchable, loosely woven, napped or delicate fabrics may require lower lay heights to maintain accuracy. For example, cutting a stable cotton poplin is very different from cutting chiffon, velvet, lycra fabric or heavy denim.
Importance of Design Matching
Design matching is a critical aspect of cutting. In plain fabrics, the main concern is grain direction and size accuracy. But in checks, stripes, plaids, borders, engineered prints and directional designs, the cutter must also consider visual continuity.
If checks or stripes are not aligned properly at seams, the finished garment looks poor. In high-quality garments, matching is expected at important points such as front placket, side seams, pockets, collar, cuffs and yokes. This may reduce marker efficiency because pattern pieces cannot be placed freely, but it improves garment appearance and customer acceptance.
In traditional Indian garments and saree-based products, border placement and motif positioning become even more important. A border may have to appear at a sleeve hem, kurta hem, dupatta edge or pallu-inspired panel. Therefore, cutting is closely linked with design understanding.
Common Cutting Room Problems
One common problem is inaccurate cutting. This may happen due to fabric shifting, blunt blades, incorrect marker placement, excessive lay height or careless handling. Even a few millimeters of variation can create problems during sewing, especially in collars, cuffs, armholes and waistbands.
Another problem is shade mixing. Fabric rolls may look similar but may belong to different shade lots. If different shades are mixed in one garment, the defect may become visible after stitching. Hence, shade sorting and roll planning are important before spreading and cutting.
Fabric defects are also a major concern. Defects such as holes, stains, slubs, weaving faults, printing defects and oil marks should be identified before cutting. If defective portions are not removed or avoided, defective garment parts may reach the sewing line.
A further issue is poor bundling and numbering. Once garment parts are cut, they must be bundled size-wise, color-wise and order-wise. If parts are mixed, the sewing room may attach the wrong sleeve, wrong collar, wrong shade panel or wrong size component. Good cutting is therefore not complete until the cut parts are properly identified and controlled.
Cutting Tools Used in Garment Manufacturing
Hand shears are used for single pieces, sampling, tailoring and small-scale production. They are simple and flexible but not suitable for large quantities.
Straight knife cutting machines are widely used in factories. They can cut many layers at a time and are useful for general garment production. Round knife machines are useful for straight lines and gentle curves but are less suitable for sharp curves and intricate shapes.
Band knife machines are used for more accurate cutting of small parts after rough cutting. Die cutting is used when identical small parts have to be cut repeatedly, such as collars, cuffs, labels, leather parts or small components. Modern factories may also use computer-controlled automatic cutting machines, which improve speed, consistency and marker utilization.
Why Cutting Accuracy Matters
Cutting accuracy directly affects garment fit. If two panels are not cut to the same shape, sewing becomes difficult and the garment may twist, pucker or hang badly. Inaccurate cutting can also disturb balance, especially in trousers, jackets, fitted garments and structured products.
Cutting also affects production efficiency. If parts do not match during sewing, operators have to adjust them manually. This slows down the line and increases defects. In severe cases, entire bundles may need re-cutting, leading to fabric loss and delivery delays.
From a cost point of view, cutting has a major impact because fabric is expensive. A good cutting plan saves fabric, reduces waste, improves sewing efficiency and helps maintain garment quality. This is why cutting room control is considered one of the key areas in garment manufacturing.
Practical Note for Students and Merchandisers
For a textile or fashion student, cutting may appear simple because it looks like the act of cutting fabric with a blade. In reality, it involves pattern knowledge, fabric behavior, production planning, quality control and cost control. A merchandiser should understand cutting because many production delays, consumption variations and quality complaints originate at this stage.
For example, if the buyer approves a garment with stripe matching, the merchandiser must understand that fabric consumption may increase. If the fabric has shrinkage, relaxation or shade variation, these issues must be controlled before cutting. If the order quantity is large, cutting capacity and lay planning become important for meeting delivery dates.
Conclusion
Cutting is the process by which flat fabric is converted into shaped garment components. Its purpose is not only to separate fabric pieces but to do so accurately, economically and in the right quantity for production. A well-managed cutting room supports smooth sewing, reduces fabric wastage, improves garment quality and helps the factory meet delivery commitments.
In garment manufacturing, mistakes made in cutting are difficult to correct later. Therefore, cutting must be treated as a technical operation requiring planning, skill and control. Good cutting is the foundation of good garment making.
