2 heads button type

Product Overview

The KR‑843 circular‑locus fuzz‑pilling tester simulates multi‑directional friction experienced by fabrics during daily wear. Under standardized pressure conditions, circular textile specimens undergo relative circular‑path rubbing against nylon bristle brush or abrasive media. After completing preset friction cycles, operators compare sample surface fuzz‑formation and pilling status against standard rating‑photos to assign pilling‑grade.

This equipment strictly follows GB/T 4802.1 specification. Multiple hardware configurations are available: button‑type 2‑head unit, touch‑screen 2‑head variant, and high‑throughput touch‑screen 6‑head model. It is widely adopted in textile mills, garment‑making factories, home‑textile producers, material‑R&D labs and accredited third‑party testing institutes for raw‑material incoming inspection and finished‑fabric surface‑durability evaluation.

Core Product Competitive Advantages

1. Multiple‑Model Options for Different‑Throughput Requirements Selectable configurations include basic 2‑position button‑control, 2‑position touch‑screen, and high‑efficiency 6‑position touch‑screen version. Customers can match model according to daily‑testing volume, balancing laboratory‑budget and batch‑sample‑processing‑capacity.
2. Precision DC‑Drive & Linear‑Guide Transmission System DC motor combined with PI closed‑loop speed‑regulating algorithm delivers steady rotation. High‑precision linear‑guide structure lowers mechanical friction, ensuring smooth, low‑noise running and highly‑reproducible friction‑trajectory for each test‑cycle. Rotation‑speed can be steplessly adjusted within working range.
3. Flexible Multi‑Mode Programmable Controller Touch‑screen‑equipped models support two independent counting logics: cycle‑count mode and time‑duration mode; both forward‑counting and backward‑counting are available. Five groups of custom‑saved parameter‑profiles allow one‑click recall for frequent‑used test‑settings. Operators can switch between fuzz‑testing and pilling‑testing workflows without repeated parameter‑input.
4. Standard‑Compliant Adjustable Test‑Condition Components Brush assembly height can be finely tuned from 2 mm to 12 mm. Matched standard weights deliver three‑level specimen‑loading pressure: 490 cN for carded fabrics, 590 cN for chemical‑fiber textiles, and 780 cN for worsted‑wool fabrics. Fully meets parameter‑requirements of GB/T 4802.1 for different fabric categories.
5. User‑Friendly Benchtop Mechanical Layout Clear specimen‑clamping mechanism simplifies sample mounting and dismounting. Anti‑vibration adjustable foot‑pads stabilise the whole unit on lab‑benches. Modular‑designed brush and friction‑disc assemblies facilitate daily disassembly, cleaning and wearing‑part replacement.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation Set instrument on level, stable lab‑bench. Power‑on the unit. Cut circular specimens of Φ112.8 mm and condition them under standard temperature‑humidity environment. Select appropriate configuration: install nylon‑brush for fuzz‑testing or abrasive‑disc for pilling‑test. Adjust brush height and fit correct pressure‑weight according to fabric‑type. Configure target cycle‑count or test‑time on control‑panel.
2. Specimen Clamping Secure conditioned circular‑fabric specimen firmly into specimen‑holding ring, ensure sample stays flat without wrinkles. Mount assembled specimen‑holder onto test station.
3. Initiate Circular‑Locus Friction‑Test Start test‑program. Machine executes preset circular‑trajectory rubbing automatically. When reaching pre‑set cycles or time‑value, tester stops running autonomously.
4. Surface‑Condition Observation & Pilling‑Grading Take‑off tested specimen. Assess degree of fuzzing and pilling under qualified illumination environment. Compare fabric surface against official standard‑rating‑photos and record final pilling‑grade result for QC‑report‑filing.
5. Batch‑Repeated‑Testing Swap new specimen and repeat above workflow for parallel‑samples. Multiple‑station model can run several specimens simultaneously to raise lab‑testing‑efficiency.
6. Post‑Test Tidying Remove specimen‑holders, clear fibre‑lint residues from brush and friction‑disc. Inspect brush bristle integrity. Replace aged or worn‑out consumables timely. Shut‑off main‑power‑supply after finishing‑all‑test‑batches.
