ASTM D3107-07 (2019) PDF

Full title and description

ASTM D3107 − 07 (Reapproved 2019) — Standard Test Methods for Stretch Properties of Fabrics Woven from Stretch Yarns. This standard specifies procedures to determine fabric stretch, fabric growth (permanent set), and fabric recovery for woven fabrics made in whole or in part from stretch yarns, using prescribed tensions and extension methods.

Abstract

Provides bench‑mark based test methods to measure the amount of fabric stretch under a specified tension, the subsequent growth after removal of the load, and the recovery after relaxation. Intended primarily for woven fabrics exhibiting relatively high stretch and good recovery, the standard includes two common tension options, defined specimen preparation, timing for measurements (immediate and after a set interval), and calculations for stretch, growth, and recovery. It explicitly excludes measurement of breaking elongation, which is covered by Test Method D5035.

Scope

These test methods cover determination of fabric stretch, fabric growth, and fabric recovery for woven fabrics that include stretch yarns. They are intended for fabrics with relatively high stretch (commonly greater than about 12%) and good recovery when tested under low specified tensions. The standard allows use of two industry‑common tension options (approximately 1.35 kg / 3 lb and 1.8 kg / 4 lb) and provides specimen handling, measurement timing (immediate and after ~30 minutes), and calculation procedures. The methods are not intended to measure breaking elongation, which is addressed in Test Method D5035. Units are given separately in SI and inch‑pound systems.

Key topics and requirements

• Definition of bench marks and specimen dimensions (including raveling to specified width) for repeatable measurement.
• Prescribed tension/weight application and two accepted tension options (1.35 kg and 1.8 kg) for stretch measurement.
• Measurement timing: immediate measurement after loading and a secondary measurement after a specified dwell time to quantify growth and recovery.
• Calculations for percent fabric stretch, permanent growth (set), and recovery, with examples and formulae.
• Directionality rules (warp/warp and filling/filling) — test only the direction(s) containing stretch yarns when applicable.
• Apparatus requirements (frame/board with clamps, separate clamp or weight attachment) and tolerances for measurement accuracy.
• Notes on units (SI and inch‑pound treated independently) and safety/handling precautions for specimens.

Typical use and users

Used by textile testing laboratories, fabric and garment manufacturers, quality assurance teams, materials R&D groups, and specification writers to evaluate the elastic performance of woven stretch fabrics for apparel (e.g., activewear, form‑fitting garments, denim blends), technical textiles, and supplier qualification. Results support product development, acceptance testing, and comparative performance specifications.

Related standards

Referential links in the standard include Test Method D5035 (breaking force and elongation of textile fabrics — strip method) and terminology standards such as D4848; the document is maintained under ASTM Committee D13 on Textiles and has historical editions (for example D3107 − 07(2015) as a prior approval).

FAQ

Q: What is this standard?

A: ASTM D3107 − 07 (Reapproved 2019) is a set of standardized test methods for measuring stretch, growth (permanent set), and recovery of woven fabrics that contain stretch yarns.

Q: What does it cover?

A: It covers specimen preparation, application of a specified tension, timing for measurements (immediate and after a set interval), and calculations to report percent stretch, growth, and recovery. It is aimed at fabrics with relatively high stretch and good recovery and is not intended to measure breaking elongation.

Q: Who typically uses it?

A: Textile test laboratories, fabric and apparel manufacturers, QA/QC personnel, R&D teams, and standards/specification authors use it to assess and verify elastic performance of woven stretch fabrics.

Q: Is it current or superseded?

A: The current approved/reapproved edition is dated 01 July 2019 (D3107 − 07 (2019)). A revision work item (WK95629) to revise the standard was recorded (work item initiated July 7, 2025), indicating review activity; until an updated approved edition is published, the 2019 reapproval remains the active version.

Q: Is it part of a series?

A: It is maintained by ASTM Committee D13 (Textiles) and is one of several D13 test methods covering textile mechanical properties (for example, D5035 for breaking force/elongation and other D13 series methods and terminology documents).

Q: What are the key keywords?

A: fabric stretch; stretch yarn; fabric growth; recovery; woven fabrics; textile testing; bench marks; tensioned test; specimen preparation.
