Fabric Width
Fabric width is a specification that indicates the width of a textile from edge to edge in the crosswise direction, and it is an important dimension related to calculating material consumption, the efficiency of marker making, and ease of cutting.
Definition and Overview
Fabric width is the width measured across a bolt or roll of fabric. In general, it refers to the full width from selvage to selvage, but it may also be shown as the usable width, meaning only the portion that can be used in the product. When placing an order or preparing specifications, it is necessary to confirm which width is being indicated.
Fabric width affects the required yardage and cutting layout even for the same pattern. A wider width does not necessarily mean less material use; marker planning should take into account the direction of the pattern, grainline, hardware shape, and whether pattern matching is required.
Types of Width and How to Read the Indication
For woven fabrics, the width including the selvage that prevents fraying at both ends and the usable width excluding the selvage or edges may differ. For knits and fabrics with fuzzy or laminated finishing, the curling of the edges and the processing condition also affect the actual usable width.
Single width and double width are general terms used to classify fabric width. However, the specific dimensional range differs depending on the material, place of origin, and trade practice, so do not judge by the term alone; confirm the stated dimensions.
- Total width: the full width of the fabric including the selvage.
- Usable width: the width set as the portion that can be used for cutting and product manufacturing.
- Fabric width indication: generally shown in cm, but tolerance and measurement conditions should also be checked.
Impact on Yardage and Marker Making
The required yardage changes depending not only on the pattern size, design, and number of pieces to cut, but also on the fabric width. For patterned fabrics, extra yardage may be needed for one-way cutting to align the direction of the pattern, or for matching stripes and checks.
For fabrics with nap, fuzzy finish, sheen, or prints, it is important to align the direction of the cutting hardware. In such cases, the freedom of marker making is reduced, so even with extra width, the required yardage may increase.
Points to Consider When Choosing and Handling
When selecting fabric, consider not only the nominal width, but also the actual width confirmed during fabric inspection, the condition of the selvage area, and any sections that must be avoided due to damage or dirt. In mass production, it is also necessary to anticipate width variation from roll to roll, and setting the marker based on the minimum width makes it easier to prevent cutting shortages.
Some materials change width after wetting, washing, or steam pressing to straighten the grain. Check the shrinkage rate and stabilize the fabric before cutting if necessary. For stretch knits, it is also important not to pull them forcibly sideways and to measure the width in a natural state.
Differences from Similar Terms
Fabric width is a horizontal dimension and is distinct from the length of the roll. A roll refers to a trading unit of wound fabric or the roll itself, and the length contained in one roll varies depending on the fabric.
The selvage is the anti-fray section at both ends of woven fabric. Depending on whether it is included or excluded, the values for fabric width and usable width may differ. Grainline is a term referring to the vertical and horizontal direction of the fabric, and does not represent the width itself.
Frequently Asked Questions
Which should be used for yardage calculation, fabric width or usable width?
As a rule, calculate using the actual usable width that can be cut. If there are damage, dirt, color unevenness, or processing defects near the selvage that make it unusable, laying out the marker based on the full width may lead to a shortage of material. Before ordering, confirm the usable range from the specification sheet or the actual fabric.
How much does the required fabric length change when the fabric width differs?
The degree of change depends on the pattern shape, size range, pattern direction, pattern matching, and cutting method. It cannot be calculated simply in proportion to the difference in width alone. For each fabric width used, calculate the required yardage with marker making that reflects the grainline and cutting conditions.
Can the stated fabric width differ slightly from the actual width?
Yes. Fabric width can vary depending on tension, humidity, winding condition, and processing conditions. Differences may also occur by lot or roll. In mass-production cutting plans, it is important not to rely only on the stated value, but to verify the actual measurement at receiving and confirm the tolerance.
