Fabric Fiber Shedding Degree Tester (Friction Method): Quantifying Linting for Q

The Fabric Fiber Shedding Degree Tester (Friction Method) is an advanced instrument designed to accurately assess the tendency of textile fabrics to shed fibers, commonly known as linting. This is a critical quality parameter for manufacturers, researchers, and testing laboratories, as excessive fiber shedding can impact product aesthetics, performance, and consumer satisfaction. By simulating real-world friction, the tester provides a reliable and quantifiable measure of fiber loss.

Precision Testing Principle: How it Works

The testing process is straightforward and highly repeatable. A fabric specimen is securely mounted on a dedicated holder. A wet abrasive material, attached to a friction head, then performs a precise series of reciprocating movements across the specimen's surface under a controlled load and for a specified number of cycles.

Following the friction cycles, the abrasive is examined. The degree of fibers adhered to the abrasive is then visually compared against a set of standardized samples. This comparative analysis allows for a precise rating of the fiber shedding, providing an objective measure of the fabric's linting propensity. This method is indispensable for:

Textile Factories: Ensuring consistent product quality and minimizing customer complaints related to linting.

Scientific Research Institutes: Investigating material properties and developing new, low-linting fabrics.

Colleges and Universities: Educating future textile professionals on material testing and quality control.

Import and Export Commodity Inspection Agencies: Verifying compliance with international quality standards.

Provincial and Municipal Textile Testing Centers: Providing essential testing services for the local textile industry.
