DIN 53867 Textile Tests - Pilling Detection with Random Rolling Pilling Test Device

The standard “DIN 53867 Textile tests - Detection of pilling by random roll pilling tester”, published by the German Institute for Standardization (DIN), describes the method for evaluating the pilling resistance of textile fabrics using a random roll pilling tester.

Pilling refers to the formation of small clumps (fuzz) of fibers intertwined on the surface of a fabric during wear or use. This can impair appearance and is an important quality parameter for clothing, upholstery, and other textiles. This standard helps manufacturers, testing laboratories, and retailers assess how well a fabric resists this surface change under simulated rolling and abrasion conditions.

This standard describes a laboratory test to determine the pilling behavior of woven, knitted, or other textile fabrics. The method simulates the mechanical stresses to which fabrics are subjected during everyday use (e.g., friction against themselves or other surfaces) by rotating fabric samples in a cylindrical chamber with a propeller (rotating blades or wings) and optional cork lining or air support.

The main objectives of the DIN 53867 standard are as follows:

• To evaluate how fabrics respond to repeated friction and abrasion.
• To evaluate the tendency of fibers to form small fiber balls (clumps).
• To measure the degree of surface wear or damage.
• To provide a repeatable method for comparing different fabrics, finishes, or fiber types.
• To provide a standardized test method for consistent results.

This method is widely accepted internationally and is often used in conjunction with the following equivalent standards:

• ASTM D3512/D3512M Standard test method for pilling resistance and other related surface modifications of textile fabrics: random tumble pilling tester
• JIS L 1076 Methods for testing pilling on woven and knitted fabrics.

In general, this method follows these steps:

• Sample preparation: Circular or square fabric samples are cut and prepared (usually stitched or in multiple directions).
• Samples are typically preconditioned under standard atmospheric conditions (e.g., 20 degrees Celsius and 65 percent relative humidity).
• Samples are placed in the test chambers of the random rolling linting test device.
• The machine rotates propellers at high speed (typically around 1200 rpm) while randomly rolling fabric samples through the hopper.
• Test duration is typically 30-60 minutes, depending on the protocol or specific requirements.
• In some assemblies, cork liners are used inside the chamber to increase wear resistance.

After testing, samples are visually evaluated for pilling, fluffing, and felting. The evaluation considers the number and size of pilling, surface turbidity, and fabric integrity. Results are typically expressed using a rating scale.

• Grade 5: No visible changes (no hair growth)
• Grade 4: Slight pilling or wear.
• Grade 3: Moderate surface alteration.
• Grade 2: Significant hair growth.
• Grade 1: Severe damage (extreme shedding)

The evaluation compares the tested samples to reference photographs or standard copies. This method can also assess the prominence of surface changes. The equipment used in these tests is designed in accordance with DIN 53867, ASTM D3512, and related standards.

The areas of application of this standard are:

• Clothing and fashion: Evaluation of shirts, trousers, sweaters, and sportswear.
• Home textiles: Upholstery fabrics, curtains, bed linens.
• Technical textiles: Automotive interiors, workwear.
• Quality control during fabric development, finishing processes (e.g., anti-pilling treatments), and final product inspection.

This standard is particularly useful for fabrics made from fibers prone to pilling (e.g., cotton, wool, polyester blends).

In short, the DIN 53867 standard defines methods for evaluating the mechanical abrasion resistance of textile fabrics, focusing particularly on pilling and surface wear. These properties are critical for assessing the durability and visual appearance of textiles during use.

This standard is widely applied in the textile industry for quality control, product development, and performance comparison.

The DIN 53867 standard is necessary because fabrics that look perfect in production can deteriorate rapidly in real-world use. This standard closes this gap by providing a reliable way to predict real-life wear behavior. The main reasons why this standard is considered important are as follows:

• It provides real-world performance.
• It provides objective and comparable results.
• It protects product quality and brand reputation.
• It supports material development and innovation.
• It ensures quality control in production.
• It is in line with international standards.
• It reduces long-term costs.

In conclusion, the DIN 53867 standard offers a reliable and standardized approach to evaluating the mechanical strength and surface appearance of textiles. By simulating real-world wear conditions, it helps manufacturers ensure that fabrics maintain their quality and appearance over time, ultimately increasing consumer satisfaction and product reliability. This standard plays a vital role in ensuring textile durability and consumer satisfaction by measuring one of the most visible signs of fabric wear.
