Full title and description

Textiles — Determination of the slippage resistance of yarns at a seam in woven fabrics — Part 1: Fixed seam opening method. This international standard specifies a laboratory method to measure the resistance offered by the thread system of a woven fabric to yarn slippage at a sewn seam by determining the force required to produce a fixed seam opening.

Abstract

ISO 13936-1:2004 defines the fixed seam opening test procedure for woven fabrics: paired seamed and unseamed specimens are tested on a constant-rate-of-extension tensile tester and the force corresponding to a specified seam opening is recorded. The method is designed to give reproducible, comparable seam-slippage data for quality control, specification and comparative testing of woven apparel and upholstery fabrics.

Scope

Specifies the fixed seam opening method for determining the resistance offered by thread systems of woven fabrics to slippage at a sewn seam. It applies to woven fabrics used in apparel and many upholstery applications but is not intended for certain industrial fabrics (for example beltings) or some highly stretchable constructions unless explicitly agreed between parties. The procedure covers specimen selection, sewing (including recommended stitch type), mounting, test-machine settings, conditioning and reporting.

Key topics and requirements

• Test principle: compare force/extension behaviour of seamed and unseamed specimens on a constant-rate-of-extension tensile tester; record force at a specified seam opening.
• Specimen preparation: detailed cutting, seam placement and sewing instructions to ensure repeatability (recommended single-needle lockstitch, stitch type 301, unless otherwise agreed).
• Apparatus and mounting: CRE tensile testing machine with appropriate grips/jaws, dimensional fixtures and recording equipment; specific jaw alignment and slack mounting procedures.
• Conditioning and pretreatment: specimens conditioned to the standard textile atmosphere and any agreed laundering or finishing pretreatments applied consistently.
• Reporting: numeric seam-slippage results, test conditions, sewing thread and stitch details, specimen orientation and any pretreatments used.

Typical use and users

Used by textile test laboratories, garment and upholstery manufacturers, material specification engineers and quality assurance teams to evaluate seam performance, to compare materials or sewing systems, and to support product development and supplier qualification. Laboratories use the method for routine quality control, acceptance testing and comparative research.

FAQ

Q: What is this standard?

A: ISO 13936-1:2004 is the part of the ISO 13936 series that specifies the fixed seam opening method for determining the slippage resistance of yarns at a seam in woven fabrics.

Q: What does it cover?

A: It covers specimen preparation, sewing requirements, test apparatus and mounting, test procedure on a constant-rate-of-extension tensile tester, conditioning and reporting rules for measuring the force required to produce a fixed seam opening.

Q: Who typically uses it?

A: Textile and garment test laboratories, quality assurance teams, fabric and apparel manufacturers, and material engineers who need quantitative, reproducible seam-slippage data for specification, comparison and quality control.

Q: Is it current or superseded?

A: The 2004 first edition is the published edition; the ISO record indicates the standard has been subject to periodic systematic review and has been confirmed in review cycles (i.e., remains the current edition unless a newer edition is issued). For purchase or to confirm the absolute current status, consult the ISO catalogue or your national standards body.

Q: Is it part of a series?

A: Yes — ISO 13936 comprises multiple parts (for example Part 1: fixed seam opening method; Part 2: fixed load method; Part 3: needle clamp method) that provide alternative test procedures appropriate for different fabrics and test objectives.

Q: What are the key keywords?

A: Seam slippage, seam opening, woven fabrics, textile testing, lockstitch, CRE tensile test, specimen conditioning.
