Описание (английский):

This document specifies methods for the evaluation of some aspects of the behaviour of nonwoven fabrics in the presence of liquids. In particular: — the liquid absorbency time; — the liquid absorptive capacity; — the liquid wicking rate (capillarity). The different aspects of absorbency can relate to various end uses of the tested products. The tests do not apply to any fabric containing super absorbent materials.

Abstract

Overview

ISO 9073-6:2025 - "Nonwovens - Test methods - Part 6: Absorption" defines standardized laboratory methods for assessing how nonwoven fabrics behave in contact with liquids. The standard covers three measurable aspects of absorbency: liquid absorbency time, liquid absorptive capacity (LAC) and liquid wicking rate (capillarity). Tests exclude fabrics that contain super‑absorbent materials.

Key topics and technical requirements

Scope and conditioning
- Sampling according to ISO 186 and conditioning per ISO 139 are required before testing. The test liquid must equilibrate with the conditioning atmosphere.
Liquid absorbency time
- Measures time for a rolled specimen to become completely wetted when dropped into liquid.
- Typical specimen: five strips (76 ± 1 mm in machining direction) each ~5 ± 0.1 g.
- Apparatus: cylindrical wire basket (80 ± 1 mm high, 50 ± 1 mm diameter, mass 3 ± 0.1 g, mesh ≈ 20 mm).
- Drop height: 25 ± 1 mm from liquid surface. Results reported as average time and standard deviation.
Liquid absorptive capacity (LAC)
- Quantifies mass of liquid held per unit mass of fabric after immersion and drainage.
- Typical specimen: five pieces 100 ± 1 mm × 100 ± 1 mm; use stacked piles if individual pieces
