Описание (английский):

ISO 7770:2009 specifies a test method for evaluating the smoothness appearance of seams in fabrics, after one or several cleansing treatments. A seaming technique is not included, since the purpose is to evaluate existing seams. This method has been developed for use primarily with type B domestic washing machines, as defined in ISO 6330, in the cleansing process. However, it may be possible to use it with type A machines, as defined in the same International Standard.

Overview

ISO 7770:2009 - Textiles: Test method for assessing the smoothness appearance of seams in fabrics after cleansing - defines a standardized, visual method to evaluate seam smoothness (seam appearance or seam-pucker) following one or more laundering or professional cleaning cycles. The method compares seamed fabric specimens to photographic or three‑dimensional (3D) replica standards under specified lighting and viewing conditions, producing a quantified seam appearance rating.

Key topics and requirements

Scope: Evaluation of existing seams after domestic or professional cleansing; does not prescribe seaming technique.

Cleansing procedures: Uses washing/drying procedures from ISO 6330 (domestic) or professional procedures in ISO 3175, as agreed between parties.

Specimens: Three test specimens, 38 cm × 38 cm, with a seam centrally placed; pinked edges or loose stitching permitted to prevent fraying.

Conditioning: Specimens conditioned 4–24 hours per ISO 139, hung with seam vertical or clamped full-width.

Viewing/lighting: Darkened room with two long cool‑white fluorescent lamps, enamel reflector and a grey viewing board matched to ISO 105‑A03 grey scale No. 2. Sidewall reflections must be minimized.

Standards for comparison: Photographic or 3D plastic replica seam‑pucker standards (single and double needle) are placed alongside specimens. Annex A supplies a digital description of the 3D replicas.

Observers and scoring: Three independent observers each rate all three specimens; ratings use a 1–5 scale (with half grades) where 5 = best appearance and 1 = poorest. The final result is the average of nine observations, reported to the nearest half rating.

Reporting: Test report must reference ISO 7770:2009 and include sample details, cleansing procedure and cycles, replica used, seam appearance rating, and any deviations.

Practical applications and users

Quality control in garment and home‑textile manufacturing to assess seam stability and appearance after laundering.

Textile testing laboratories performing standardized seam‑pucker assessments for product specification, compliance, or comparative studies.

Product development and R&D teams evaluating fabric‑seam combinations, thread choices, or finishing treatments.

Laundry and care service providers validating professional processes that preserve seam smoothness.

Standards bodies and auditors requiring documented, reproducible assessment of post‑cleaning seam appearance.
