Applications:

G275 dry fallen wadding tester, is mainly used for the evaluation of shedding of raw materials used in surgical orders, surgical gowns, and clean clothes.

It is applicable to the performance verification of new products, quality control of the production department, and the of material properties for the third-party testing organization, the product performance verification laboratory, and the quality and technical supervisiondepartment, etc.

Product Information:

The G275 dry fallen wadding tester evaluates shedding performance of medical nonwovens and textiles under dry conditions by subjecting samples to torsion and compression. Air drawn during twisting is analyzed with a laser dust particle counter to count and classify particles. It features a high-resolution touch screen, monitors 8 particle size channels, and stores extensive data, useful for air quality and filter tests.

Accessoriess

A brief description of the accessories for the atomization tester is as follows:
Core Components: Fogging cup (for holding the sample), cooling tray/plate (providing a cooling environment), glass plate (for gloss method testing) or aluminum foil (for gravimetric method testing).
Measuring Instruments: Gloss meter (for measuring gloss changes), electronic balance (high precision, for weighing changes in aluminum foil weight).
Auxiliary Accessories: Sample clamping ring (for fixing the sample), beaker (for holding the medium), sealing ring (to ensure airtightness), sampler (for taking and placing samples).
Calibration Supplies: Calibration plate (for calibrating the measuring instrument), standard samples (for verifying test performance).

Test Procedures

The operation method of the atomization tester includes the following steps:
Sample Preparation: Pre-treat the sample according to the testing standards, such as cleaning, drying, and aging under specific conditions.
Instrument Settings: Adjust the instrument's temperature, humidity, airflow speed, and other parameters according to the characteristics of the sample and testing requirements.
Test Execution: Place the sample in the test chamber, start the instrument, and record the test time and the amount of mist in the mist collection device.
Data Analysis: Calculate the atomization rate, mist distribution uniformity, and other indicators based on the test data to evaluate the sample's atomization performance.
When operating the atomization tester, users should pay attention to the following:
Ensure the sample is clean and dry before testing.
Adjust the instrument's temperature, humidity, airflow speed, and other parameters to simulate the temperature and humidity conditions in actual application scenarios.
Record the test time and the amount of mist in the mist collection device.
Calculate the atomization rate, mist distribution uniformity, and other indicators based on the test data to evaluate the sample's atomization performance.

FAQ

1. What is this product?
The dry fallen wadding tester evaluates the tendency of textiles, nonwoven fabrics, carpets, and fiber-based materials to release fibers or lint under mechanical agitation in dry conditions. It provides quantitative data on fiber shedding, which is critical for product durability and quality control.
2. What is it used for?
It is used to assess shedding performance of clothing, home textiles, industrial fabrics, and nonwovens. It helps manufacturers control product quality, optimize fiber blends, evaluate surface treatments, and ensure compliance with industry standards.
3. How does it work?
Samples are subjected to standardized mechanical agitation or tumbling in the tester. Released fibers are collected on filter pads or trays, and the mass or quantity of fallen fibers is measured. Test parameters, such as duration, agitation speed, and sample size, are adjustable to simulate real-life wear conditions.
4. Why is it important?
Excessive fiber shedding affects product aesthetics, performance, and safety. Accurate testing ensures compliance with textile and nonwoven standards, improves consumer satisfaction, and supports R&D in fiber blends, finishing techniques, and surface coatings.
5. Which industries use it?
Widely used in apparel manufacturing, home textiles, automotive interiors, nonwoven production, filtration materials, and laboratory research for fiber-based products.
