Blackboard Shaker
The Blackboard Shaker is a precision instrument designed to evaluate the appearance quality of yarns. By shaking yarns of specified density across a blackboard surface, it allows standardized visual assessment and comparison. It is widely used in textile laboratories, quality control departments, and research institutes for yarn inspection.
Application Scenarios
(1) Apparel fabrics: cotton, polyester, wool, nylon, spandex, and blended yarns before weaving or knitting
(2) Home textiles: yarns used in bedding, upholstery, curtains, table linens
(3) Industrial fabrics: yarns for automotive interiors, filtration materials, protective garments
(4) Functional textiles: flame-retardant yarns, coated yarns, waterproof/breathable laminates
(5) Laminated or composite materials: PU/PVC synthetic leather yarns, soft-touch coatings, printed laminates
(6) Smart and sensitive textiles: temperature-adaptive or conductive yarns for wearable electronics
(7) Laboratory and R&D testing: fiber and yarn development, yarn twist, density, and uniformity evaluations
(8) QC and inspection: yarn quality control in textile mills, spinning mills, and inspection institutes
(9) Educational and research purposes: textile engineering studies, yarn property demonstrations, and standard compliance testing
(10) Comparative evaluation: assessing yarn appearance, density, thickness, and consistency across different batches or suppliers
Compliance Standards
(1) GB/T 999 — Test methods for textile yarn
(2) GB/T 398 — General rules for textile testing
(3) GB/T 5324 — Test method for yarn appearance
(4) FZ/T 32004 — Test methods for yarn twist and density
(5) FZ/T 32005 — Yarn appearance quality evaluation
(6) ISO 2060 — Textiles — Yarn numbering (direct system)
(7) ASTM D1423 — Standard Test Method for Yarn Twist
