Fabric air permeability tester
Fabric Air Permeability Tester
Fabric Air Permeability Tester is a lab instrument used to measure how easily air passes through a fabric. It quantifies the air permeability, which is crucial for evaluating breathability, comfort, and functional performance in textiles. Purpose Fabric Air Permeability Tester: It determines the rate of airflow through a fabric sample under a set air pressure, typically reported in units like cm³/cm²/s or L/m²/s. Working Principle: The tester creates a pressure difference across the fabric sample and measures the volume of air flowing through it. Higher air permeability means the fabric is more breathable. Main Components of Fabric Air Permeability Tester: - Test Head / Clamp: Holds the fabric securely without leakage. - Pressure Regulator: Maintains a constant air pressure during testing. - Flow Meter or Digital Sensor: Measures the actual airflow rate through the fabric. - Display Unit: Shows readings of air permeability instantly.

Color fastness to washing machine
COLOR FASTNESS TO WASHING MACHINE
Color fastness to washing machine refers to a fabric’s resistance to fading or bleeding when subjected to washing processes. This test measures how well the dye or colorant stays on the fabric when exposed to water, detergent, heat, and mechanical action—conditions typically found in household or industrial washing machines. Purpose of Color fastness to washing machine - To evaluate the durability of dyed or printed textiles during laundering.- Essential for determining fabric quality and suitability for end-use (e.g., clothing, upholstery). Test Method Usually based on international standards such as: - ISO 105-C06 - AATCC 61- IS 3361- AATCC 28/61/132/151/190, BS 1006 C01-C05, ISO 105 Part C01-C06/C08/D01, M&S C4/C5/C10A/P3B, FTMS 191-5610, NEXT TM2/3/5, GB/T 5711/3921 Procedure (Simplified)1. Sample Preparation: - A fabric specimen is stitched with undyed adjacent fabrics (usually cotton or wool).2. Washing: - Washed in a laboratory washing machine using standard detergent, water, and specific temperature/time settings (e.g., 40°C for 30 minutes).- Drying: - After washing, the sample is dried, typically air-dried or tumble-dried.4. Evaluation: - Color change and staining on adjacent fabrics are assessed using a gray scale (1 to 5 scale; 5 = no change, 1 = severe change). - Results may also be evaluated visually under standard lighting.
- Supports Brand Reputation - Reliable color fastness contributes to a premium product image and consistent performance.4. Compliance with Standards - Meets industry requirements (e.g., ISO, AATCC), crucial for export, certifications, and regulatory compliance.
- Improves Process Control- Helps identify dyeing or finishing process issues early, leading to better production control.6. Reduces Rework and Waste - Minimizes production losses due to color defects after washing.
- Essential for Specific End Uses - Critical for items subject to frequent washing (e.g., uniforms, baby clothes, hospital linens).8. Supports Material Selection - Guides textile manufacturers in choosing appropriate dyes and fabrics for specific applications.
- Assessment of Color Change and Staining- Evaluates both the fabric’s color retention and the staining of adjacent fabrics using grey scales (1 to 5 rating).4. Multi-Fiber Fabric Use - Tests include fabric stitched with adjacent test strips (cotton, wool, etc.) to assess color bleeding onto different fibers.
- Multiple Test Options - Includes domestic, accelerated, and industrial washing conditions depending on the end-use of the fabric.6. Temperature and Time Control - Precise control over wash temperature (e.g., 40°C, 60°C) and duration (e.g., 30 mins), simulating specific washing cycles.
