Product Details

In the daily process of shaping and high temperature ironing, dyes heat stability will affect the appearance of fabrics.. Dyes heating , heat transfer properties will cause the change of fabric color.

Sublimation fastness tester (large) is used to determine the hot pressing ironing and dry heat (sublimation) color fastness properties for all kinds of dyed printing material and fabrics, it also can be used for determination the resistance to chlorine damage, textile bleaching products, scorch yellowing test, disperse dye sublimation fastness test, dye fastness test, high temperature dimensional stability. It is commonly used in printing and dyeing fabrics, textile auxiliaries clothing industry.

GB/T 6152-1997 Tests for colour fastness–Colour fastness to hot pressing ( Sublimation Test Standard)

1.Sublimation fastness definition:

Sublimation fastness is to determine the color of various types of clothing materials, the ability of high temperature resistance and the color retardant of the clothing material under heat pressure or heat drum process.

2.Methodology:

①、Dry pressing: The dry specimen is subjected to a certain time in the pressure device with the specified temperature and the specified pressure. The Gray sample card is used to evaluate the color of the specimen after testing.

②、Tidal pressing: With a wet cotton-lined fabric covered, The dry specimen is subjected to a certain time in the pressure device with the specified temperature and the specified pressure. After the test, the gray sample card was used to evaluate the discoloration of the specimen and the stained color of the lining fabric.

③、Wet pressing: With a wet cotton-lined fabric covered, The wet specimen is subjected to a certain time in the pressure device with the specified temperature and the specified pressure. After the test, the gray sample card was used to evaluate the discoloration of the specimen and the stained color of the lining fabric.

3.Sublimation fastness testing procedure

Sample preparation:

The sample size is 40mm×100mm. The size of the accompanying fabric is the same as the sample. The specimen should be put in the standard atmosphere, which is humidity (65±2)% and temperature (20±2)℃.

4.Test procedure

Turn on the power.

Switch the button to ironing or sublimation. The lamp of ironing or the lamp of sublimation flashes which mean the heater starts heating.

Set the test temperature.The pressure of the temperature depends on the type of the fiber, the material of clothing or the structure of the clothing. For instance, the recommended temperature of the blended fiber should be compatible with the least heat resistant fiber

Set time in accordance to the test requirement. Commonly, the specimen would be put under the pressure and specified temperature for 15s.

When the temperature reaches the test requirements, open the heating box and put into the sample. If it is dry pressing, the specimen, which does not need to be accompanied with the lining fabric, can be heated directly. If it is moisture pressing, the specimen and the lining fabric are soaked. Wheter the lower plate of the heating device is heated or not, it should always be covered with asbestos sheets, wool flannel and dry, dyed cotton.

Put down the heating plate, and make the sample under the pressure of 4kPa, and press the Start button immediately, when the timer began to slack. After 15s, lift the heating plate.

Take out the specimen and immediately use the corresponding Grey sample card to evaluate the color change of the specimen.

5.Results

To evaluate the discoloration of the specimen by gray sample card 250, and then put the specimen in the standard atmosphere. After 4h, make the evaluation again.

To evaluate the staining of the lining fabric by gray sample card 251. To use the heavier staining side of the cotton-lined fabrics to evaluate.

FAQ

(1)What is a Scorch Tester / Sublimation Fastness Tester used for?

A Scorch Tester / Sublimation Fastness Tester is used to evaluate textile color stability under high temperature and pressure conditions. It helps determine whether dyes will fade, change color, or transfer during ironing, heat pressing, or thermal processing.

(2)What is the difference between scorch testing and sublimation fastness testing?

Scorch testing mainly evaluates color changes caused by heat exposure, while sublimation fastness testing focuses on dye migration or transfer caused by high temperatures, especially in synthetic fabrics such as polyester.

(3)What materials can be tested with a sublimation fastness tester?

A Sublimation Fastness Tester can test dyed fabrics, printed textiles, polyester materials, blended fabrics, garments, and heat transfer printing products to evaluate their thermal color stability.

(4)Which standards are commonly used for heat and sublimation fastness testing?

Common standards include ISO 105-X11, ISO 105-P01, AATCC 117, AATCC 133, and GB/T 6152. The applicable standard depends on the material type and customer requirements.

(5)How to choose a suitable Scorch Tester?

Selection should consider temperature range, pressure control, test method compatibility, specimen size, standard requirements, and laboratory workload to ensure accurate and repeatable textile heat fastness testing.
