1. Packaging and label verification
Original packaging details
Authentic yarns usually use thickened kraft cartons with coated paper labels on the outside, marking the brand, specification, color number, batch number and customs information, and the cartons are not easy to deform;
The inner dust bag must be printed with the brand logo, the spool material is high-hardness kraft paper, and the inner printing is clear and uniform in style.
Label and woven label traceability
Label paper printing uses industrial-grade equipment, with high-definition fonts and uniform imprints (such as labels containing "vi-tex" and other series of logos);
High-end yarns must be accompanied by woven labels that can be traced back to the brand, which can be verified through the official website or authorized channels.
2. Material and process testing
Fiber property identification
Touch and gloss: Authentic cashmere/wool yarns have a delicate and soft touch and a natural gloss, while imitations may be rough or reflective;
Burning test: After burning, wool/cashmere smells like burning hair, and the ashes are crisp black particles, while chemical fibers melt and clump and emit a plastic smell.
Yarn process characteristics
Detwisting experiment : Ring spinning yarn has no strength after complete detwisting, air spinning is easy to break locally after detwisting, and vortex spinning retains the yarn core strength, which can distinguish the process type;
High-count yarn matching : Mercerized cotton above 100S needs to be adapted to 240N precision needle type, and inferior yarn is easy to cause loose fabric or uneven needle eyes.
3. Supply chain and document verification
Supplier qualification verification
Requires to provide customs declaration, brand authorization and production batch records. Top-level yarns are mostly circulated through official agents, and bulk sources need to be vigilant;

4. Sample and functional testing
Shrinkage and pilling test
Authentic wool yarn shrinks less than 5% after washing, and inferior blended yarn is prone to serious deformation;
Rubbing the surface with a brush, imitation products (such as polyester imitation cashmere) are prone to pilling quickly.
Environmental certification verification
Using undyed black wool, the natural pigment composition of the fiber can be verified through the test report.
Multiple verification methods (logo, material, supply chain) combined with physical testing can effectively avoid low-end counterfeits and ensure the authenticity and quality of high-end yarns.
