Fabric Shrinkage Test Log - AATCC 135 Home Laundering

This template records the full AATCC 135 home laundering workflow for fabric specimens, from identification and pre-wash measurements through wash conditions, post-wash measurements, and final disposition. It is designed to document dimensional change in length and width against an allowable shrinkage limit. The log also captures photo evidence and sign-off so the result is traceable. Use it as a controlled record for lab, QA, or vendor testing.

Use it when the question is specifically whether a fabric, knit, or garment component shrinks within tolerance after home laundering. A general inspection form is too broad because it usually does not capture conditioning, wash program, drying method, or percent shrinkage calculations. This log is better for incoming material qualification, style approval, supplier verification, and complaint investigations. It is not meant for visual defect checks unrelated to dimensional change.

A trained QA technician, lab technician, or textile inspector should complete it, following the site SOP for specimen handling and measurement. The person recording the data should be the same person or team responsible for maintaining measurement consistency and traceability. If your process requires it, a supervisor or quality manager can review the result and disposition before release. Clear ownership matters because small measurement errors can change the pass/fail outcome.

That depends on your quality plan, but common triggers include new style approval, fabric lot changes, supplier changes, process changes, and customer complaints. Many teams also test at defined incoming inspection intervals or when a material is used in a critical fit-sensitive product. The key is to test whenever a change could affect dimensional stability. This template supports repeatable logging each time the test is run.

Yes, it is structured to support AATCC 135 home laundering documentation by capturing specimen identification, laundering conditions, and dimensional change results. It also fits broader quality management expectations for traceability and controlled records under ISO 9001-style systems. If your organization uses internal textile SOPs or customer-specific limits, those can be added in the reference specification field. The template does not replace the test method itself; it records the evidence and outcome.

The most common issues are inconsistent gauge marks, missing conditioning before measurement, incomplete wash settings, and forgetting to record the drying method. Another frequent problem is calculating shrinkage from the wrong baseline or mixing up length and width values. Teams also sometimes skip photo evidence, which makes later review difficult. This template helps prevent those gaps by separating setup, laundering, measurement, and sign-off.

Yes, and you should. The allowable shrinkage limit, specimen count, style identifiers, and reference specification should match your product requirements, customer contract, or internal SOP. You can also add fields for fabric blend, finish, machine model, or operator if those affect your process. The template is a starting point, not a fixed test method.

An ad hoc spreadsheet can capture numbers, but it often misses the structure needed for traceability, review, and consistent pass/fail decisions. This template prompts the user to record the exact items that matter in AATCC 135 testing, including pre-wash setup, laundering conditions, and disposition. That reduces rework when results are questioned by suppliers, customers, or internal auditors. It also makes it easier to compare tests across lots and styles.
