Industry Weight
Industry weight is a value that indicates the weight per unit area of textile, generally expressed in grams per square meter, and serves as a guide for judging textile thickness and bulk.
Definition and Overview
Industry weight is a standard that indicates the mass per square meter of textile. It is usually expressed in g/m2 or gsm, and the larger the value, the greater the amount of material per unit area. It is basic information used in textile planning, ordering, and quality checks.
Industry weight indicates the weight of the textile and does not show thickness itself. Even with the same industry weight, thickness, appearance, and wear comfort differ depending on the type of fiber, structure, thread thickness, fuzzy finish, or coating.
Relationship to Hand and Performance
In general, textiles with a lower industry weight are lighter, thinner, and easier to create sheerness and suppleness. Textiles with a higher industry weight may lead to more body, durability, warmth, and a stable silhouette. However, these are judged in combination with the material and structure.
For example, even with the same industry weight, woven fabrics and knits differ in stretch and bulk. Also, materials such as wool that easily trap air, and fuzzy textiles, may feel thicker and warmer than their numbers suggest.
Main Applications and Textile Selection
Industry weight is a comparison indicator when considering the lightness, drape, strength, and seasonal feel required for applications. Lightweight textiles may be chosen for thin shirts and linings, moderately firm textiles for medium-weight bottoms and jackets, and heavier textiles that take durability into account for bags and workwear.
However, applications cannot be determined by industry weight alone. It is important to check the structure, density, blend ratio, finishing, and textile width as well, and to confirm sheerness, stiffness, and drape with the actual roll or swatch.
- If lightness is important, check sheerness and strength in addition to industry weight.
- If you want to keep the shape, check not only industry weight but also the structure and firmness.
- For outerwear or material applications, also check test items such as abrasion resistance and tear strength.
Handling and Production Notes
Industry weight may change depending on finishing conditions, moisture content, and processing. If washing or shrinkage changes the area of the textile, the weight per unit area also changes. During mass production, share the testing conditions and allowable range with the trading partner for confirmation.
When estimating fabric consumption and product weight, combine industry weight with textile width and required dimensions. Simple calculations that do not consider grain direction, grain, cutting loss, or shrinkage rate will differ from the actual required amount, so advance cutting design is necessary.
Differences from Similar Terms
Density is an index for woven fabrics that shows the number of warp and weft threads within a certain length. Even if the industry weight is heavy, some textiles are woven loosely with thick threads, while others are woven densely with fine threads, so industry weight and density do not mean the same thing.
Yarn count and denier are units that indicate thread thickness. In contrast, industry weight indicates the weight per unit area of the entire textile. Thickness is a separate value measured with a thickness gauge, and cannot be determined directly from industry weight.
Frequently Asked Questions
If the industry weight is the same, are the thickness and durability of the textile also the same?
Not necessarily. Thickness and durability depend on the specific gravity of the fiber, thread thickness, woven or knitted structure, density, and fuzzy or resin finishing. Industry weight is used as a starting point for comparison, and thickness, tear strength, abrasion resistance, and hand are confirmed using the actual product or test values.
Does industry weight change after washing?
It may change. If washing causes the textile to shrink, the area becomes smaller, so the weight per unit area changes. Differences also arise depending on the type of processing and the moisture condition at the time of measurement, so for product development it is important to check dimensional changes and hand before and after washing.
