ASTM D3882-08 (2025) PDF

Full title and description

Standard Test Method for Bow and Skew in Woven and Knitted Fabrics — ASTM D3882-08(2025). This standard specifies procedures to determine the amount and direction of bow and skew (distortion) of filling yarns in woven fabrics and courses in knitted fabrics, and may be applied to printed geometric designs such as plaids.

Abstract

This test method defines how to measure bow and skew — the deviation of yarn paths or courses from the normal perpendicular to the fabric length — using prescribed specimen preparation and measurement lines. Results are used for quality control, acceptance testing, and comparison between lots or processes where pattern matching and dimensional stability are important.

Scope

This test method covers the determination of bow and skew of filling yarns in woven fabrics and of courses in knitted fabrics; it can also be applied to measure distortion in printed geometric designs (for example, plaids). The standard presents measurement principles, specimen preparation, and reporting conventions and treats SI and inch‑pound units as separate standards. The method is intended for acceptance testing, quality control and for identifying sources of distortion introduced during fabric manufacture, finishing, or subsequent processing.

Key topics and requirements

• Definition of bow and skew and their visual/functional significance for patterned and plain fabrics.
• Specimen selection and orientation to ensure representative measurement.
• Measurement lines and procedures for locating maximum bow or skew across a roll or sample.
• Reporting formats including units (SI or inch‑pound) and acceptance criteria for roll or lot evaluation.
• Notes on common causes (fabrication, dyeing, tentering, finishing) and recommendations for statistical comparison between laboratories.

Typical use and users

Used by textile mills, fabric finishers, quality laboratories, apparel and home‑textile manufacturers, technical textile specifiers, and test laboratories for acceptance testing, troubleshooting production issues (such as mis‑tentering or uneven tension), and ensuring pattern matching for printed or patterned fabrics.

Related standards

Frequently referenced alongside other textile dimensional and construction standards (for example, standards for fabric width, mass per unit area, yarn crimp, and related test methods). It is often used in conjunction with internal quality specifications and with other ASTM textile test methods for fabric characterization and acceptance sampling.

FAQ

Q: What is this standard?

A: ASTM D3882-08(2025) is the Standard Test Method for Bow and Skew in Woven and Knitted Fabrics, a short ASTM procedure describing how to measure distortion (bow and skew) in woven and knitted textile constructions.

Q: What does it cover?

A: It covers specimen selection and orientation, measurement techniques to locate and quantify maximum bow or skew, reporting conventions, and guidance on interpretation for acceptance or troubleshooting. It applies to both construction-related distortion and printed geometric patterns.

Q: Who typically uses it?

A: Textile manufacturers, finishers, testing laboratories, apparel and home‑textile companies, and any organization that needs to control or verify fabric dimensional stability and pattern accuracy.

Q: Is it current or superseded?

A: The D3882-08 text has been maintained and is listed with a 2025 reapproval notation (shown as D3882-08(2025) in commercial standards catalogs), indicating the 2008 method was reaffirmed for continued use in 2025. Users should consult the current ASTM catalog or official distributor notices for the latest reapproval or revision status before relying on the standard for compliance purposes.

Q: Is it part of a series?

A: It is one of a set of ASTM textile test methods covering fabric dimensions, mass, yarn crimp, and other construction and performance tests; it is maintained by the ASTM D13 committee (textiles).
