Fusible interlining performance cannot be judged reliably by pulling one sample by hand. Similar peel-force values can represent different problems depending on whether adhesive remains on the shell, the interlining tears, or the layers separate cleanly at the bond line. Before bulk production, record both the measured force and the failure mode to compare material combinations and press settings accurately.<\/p>\n

Define the test purpose and acceptance criteria first<\/h2>\n

Test timing and conditions differ depending on whether the goal is initial bond strength or durability after washing or dry cleaning. Define garment use, care method, application area and acceptable shell damage, then compare candidates with an approved sample or internal specification. A range based on a proven garment construction is often more practical than one universal force value.<\/p>\n

Prepare consistent specimen direction and width<\/h2>\n

Woven shells and woven interlinings can behave differently along warp and weft directions. Keep specimen width, length, shell grain, interlining grain and sampling location consistent, and measure several replicates. Edge areas or wrinkled sections that are not representative should be recorded separately as abnormal samples.<\/p>\n

Measure after conditioning rather than immediately after fusing<\/h2>\n

Immediately after pressing, the adhesive may still be cooling and setting, which can make results unstable. Cool the specimen flat and condition it for a defined time and environment before testing. Recording immediate and conditioned values separately can reveal bond changes during cooling.<\/p>\n

Standardize peel speed and starting position<\/h2>\n

Peel speed, angle and the pre-separated starting length can substantially change the result for the same specimen. Mount the specimen consistently and record the initial peak separately from the stable peel region. If manual comparison is also used, keep pulling length and speed as consistent as possible.<\/p>\n

Classify the failure mode together with the force<\/h2>\n

Distinguish clean interfacial separation, uneven adhesive transfer and material failure in which the shell or interlining tears. Material failure may indicate a strong bond, but it can also signal damage risk for a delicate shell. Photograph both separated surfaces and note where adhesive remains to support diagnosis.<\/p>\n

Retest after care, heat and humidity exposure<\/h2>\n

Adequate initial peel strength can decline after repeated care, steam, hot storage or humidity exposure. Retest with the same direction and speed after the intended care cycle, and inspect bubbling, edge lift and hand change at the same time. When production is split across a Korea and Vietnam textile material supply network, sharing the same reference specimen and test sequence helps reduce press-line variation.<\/p>\n
