SIST EN 15598:2009

Overview

SIST EN 15598:2009 is a European Standard developed by CEN that specifies a precise test method to determine the resistance of terry fabrics to pile loop extraction. This standard measures the force required to withdraw a loop from the foundation of terry fabrics, which are widely used in home textiles such as towels and bathrobes. The test ensures fabric durability and quality by evaluating loop strength, an essential factor influencing fabric performance and lifespan.

Utilizing a constant-rate-of-extension tensile testing machine, this method quantitatively assesses the mechanical resistance of loops against pulling forces, providing manufacturers, quality controllers, and textile engineers with critical data on terry fabric resilience.

Key Topics

• Scope of Testing: Determination of force needed to extract a pile loop from woven terry fabric.
• Test Principle: Application of an increasing load to a loop until it dislodges from the fabric foundation.
• Equipment Used: Constant-rate-of-extension (CRE) tensile testing machine with stress and strain recording capabilities.
• Specimen Preparation: Test samples sized 120 mm × 25 mm, oriented with the yarn arrangement, conditioned under defined atmospheres (EN ISO 139).
• Test Procedure: Folding specimens, hooking the loop, and applying tensile force at a speed of 100 ± 10 mm/min until a 10 mm extension or peak load.
• Result Calculation: Force at 10 mm extension or the peak load prior to this point is recorded to 0.05 N precision; averaging multiple specimens for reliable results.
• Reporting Requirements: Includes standard reference, fabric description, individual and average test forces, and any deviations from the standard.

Applications

• Quality Control in Textile Manufacturing: Ensures terry fabrics meet strength requirements and performance standards.
• Product Development and Innovation: Assists designers and engineers in assessing the durability of new terry fabric constructions and yarns.
• Regulatory Compliance and Certification: Supports manufacturers in fulfilling European textile product safety and quality regulations.
• Lab Testing and Research: Provides a standardized method for academic and industry research focusing on pile fabric properties.
• Home Textiles and Apparel: Guarantees loop strength in products such as towels, bathrobes, and linen, affecting consumer satisfaction and product longevity.

Related Standards

• EN ISO 139: Textiles - Standard atmospheres for conditioning and testing – Establishes the environmental conditions required for specimen conditioning in the EN 15598 test method.
• Other Textile Testing Methods under CEN/TC 248 – Covers various performance parameters including abrasion resistance, tensile strength, and dimensional stability of textiles.

By adhering to SIST EN 15598:2009, textile professionals benefit from a consistent, reliable, and repeatable method to assess terry fabric resistance to pile loop extraction, optimizing product quality and consumer confidence.
