Direct answer
Approve reinforcement only after the complete PP sample preserves strength, stretch, recovery and the dressing path. A local pull check can answer one narrow question, but it cannot prove that the garment still opens, passes over the body, moves and returns as intended.
THE FAILURE PATH
A local fix can move the failure to the whole-garment level.
Carry the knit load
The strap appears to need more support because the knitted garment pulls on it.
Insert non-stretch tape
The tape reduces local stretch where it is attached, even when that change is not visible on a flat table.
Test entry and movement
Put the complete sample on a person and check the opening, range of motion and recovery after movement.
Choose the construction
Only then decide whether to keep, revise or remove the reinforcement before bulk production.
FUNCTIONAL TEST BRIEF
Assign the next sample four jobs, not one.
Does the support reach the right structure?
Check where the weight enters the strap, seam or opening and whether the reinforcement distributes or merely blocks movement.
Does the garment still extend and return?
Compare the knit's stretch direction and recovery with the added tape, facing, lining or end treatment.
Can a person get in, out and move?
Test the real entry and exit path, seated and standing movement, and any action the garment must allow.
Can the decision be carried into bulk?
Record placement, length, fastening, measurement reference and the condition that would trigger another sample.
CASE 12 / RECORDED PROCESS
The tape solved a local load concern, then removed the dressing function.
On an alpaca-and-silk blended knitted jumpsuit, non-stretch tape was added behind the straps to reduce pull on the knit. Once 50 finished garments were tried on, the pieces could not pass over the hips because the tape had removed the stretch needed for entry.
Recorded source: `case-12`. Shipment, customer acceptance and post-repair strap strength were not recorded.
CLAIM BOUNDARY
Use the case to set a test boundary, not to promise an outcome.
What the record supports
- Non-stretch reinforcement changed the garment's stretch path.
- The complete garment could not pass over the hips during try-on.
- Removing 100 tapes from 50 garments took two people four days.
- PP-stage movement and dressing tests would have exposed the conflict earlier.
What remains open
- Whether the repaired garments were sent or accepted
- Whether the original strap load was retested after removal
- Long-term recovery, wear and durability
- A universal construction rule for every strap or opening
