An interlining specification sheet helps garment manufacturers understand what they are purchasing and whether the material suits their production requirements. Instead of comparing products by name alone, buyers should review the technical details that describe the base material, adhesive coating, weight and supply format. Knowing how to read an interlining specification sheet can make sourcing decisions more accurate and reduce misunderstandings between buyers and suppliers.
Check the Construction and Material
Start by identifying whether the interlining is woven, non-woven or knitted. These terms describe how the base material is constructed and should not be treated as interchangeable. Woven interlining is formed from interlaced yarns, while non-woven interlining is made by bonding fibres together.
The material composition is another important detail. A specification may identify polyester or another fibre type. This information helps buyers understand the product’s base construction and compare it with the requirements of the garment.
Understand GSM and Adhesive Coating
GSM refers to grams per square metre and indicates the material’s weight. It is useful when comparing different grades, but it does not independently determine whether an interlining is suitable. The required weight depends on the outer fabric, garment component and desired finish.
For fusible interlining, check the adhesive type and coating method. These details help identify how the product is designed to bond with the outer fabric. Also review any stated fusing guidance, but confirm that the recommended conditions are appropriate for the actual fabric and equipment being used.
Review Width, Colour and Roll Length
Width and roll length affect material planning and cutting calculations. Buyers should compare these details with their production requirements rather than assuming that all interlining rolls follow the same format.
Colour is also relevant, particularly when the outer fabric is light, dark or relatively transparent. Ask for samples if the specification does not make the visual suitability clear.
Confirm the Details Before Ordering
A useful specification review should include construction, fibre composition, GSM, adhesive coating, colour, width, roll length, care information and any relevant certification. Buyers should also confirm the minimum order quantity and commercial terms directly with the supplier.
For example, the listed non-woven fusible interlining range supplied by Double Ghoda includes bonded polyester fibres, PES coating, 30–80 GSM, 100 cm width, 90-metre rolls and white or black colour options. Reviewing these details alongside a production sample helps buyers make a more informed sourcing decision.
