Application of G247 Wrinkle/Heat and Sublimation Fastness Tester

Customer Background

A leading textile testing laboratory specializes in fabric color fastness and heat treatment performance evaluation, providing quality certification services for domestic and international apparel and home textile manufacturers. The laboratory faced challenges such as dimensional changes and color variations of fabrics under heat press and dry heat conditions, while also needing to assess sublimation and reactive dye fastness. A precise, controllable, and user-friendly instrument was required to meet multiple testing standards.

Application Requirements

Wrinkle/Heat Fastness Testing: Evaluate dimensional stability and color fastness of fabrics under high-temperature ironing conditions.

Sublimation Fastness Testing: Measure dye sublimation behavior of disperse dyes during heat treatment.

Multi-standard Compliance: Meet ISO 105 X11, AATCC 92/114/117/133, GB/T 5718/6152, and other international and domestic standards.

Precision Control: Accurate setting of temperature, pressure, and heating duration to ensure reliable test data.

Solution

The laboratory adopted the G247 Wrinkle/Heat and Sublimation Fastness Tester, offering the following key advantages:

Precise Temperature Control: Independent digital controllers for upper and lower heating plates, accuracy up to 1°C; test range 120–230°C, maximum 250°C.

Controllable Pressure and Sample Weight: Adjustable heating plate spacing and sample weight; heating plate surface pressure 4±1 KPa (40 cm²) for uniform testing.

Timer with Alarm: Built-in audible timer to precisely control testing duration, eliminating human error.

Versatile Testing Capabilities: Supports heat press and dry heat fastness, chlorine damage tests, bleached fabric yellowing, disperse dye sublimation fastness, and reactive dye wet-heat fastness.

Compact Design: Dimensions approximately W250 × D300 × H230 mm, saving lab space and enabling easy operation.

Application Results

Integrated multiple standard tests in one device, reducing equipment changeover and operational time.

High repeatability of test data, with significantly improved temperature and pressure control precision.

Effectively supports customers in apparel and home textile quality certification, improving testing efficiency and service quality.
