gb3920 rub fastness meter electric rub fastness meter

The electric color fastness tester is mainly composed of a control system and a friction system. The sample is fixed on the end of the base with sandpaper pasted by the sample clamp Place the rubbing head wrapped with a white cotton cloth on the sample and after rubbing for a certain number of times, observe the sample and use the gray card to determine the degree of color adhesion compare and evaluate the white cotton cloth, and make a judgment on the fabric sample dyeing or surface coating stability, to provide reference data for material evaluation and selection. This instrument is suitable for yarn, dyed yarn, printed and dyed textiles and all substances on or in toy products.

Product Introduction

Application Scope :

Electric Rub Color Fastness Tester is used to test the dry/wet rub colorfastness of colored fabrics such as cotton, chemical fiber, blended fabrics and leather degree of testing. G238BB is suitable for testing the color fastness to abrasion of fabrics in dry and wet conditions, as well as frequent and periodic tests. The tester makes the sample rub against the white cotton cloth repeatedly for a certain number of times within a certain pressure and within a certain stroke, and evaluates the decolorization level by comparing the white cotton cloth with the mottled gray sample card, which is a basis for improving of dyeing fabrics. Equipped with digital electronic preset counter.

Main Functions:

Electric Rubbing Color Fastness Tester mainly consists of a control system and a friction system. sample clamp to secure the sample to the sandpaper-taped end of the base, place the wrubbing head wrapped with white cotton cloth on the sample, and observe the sample after rubbing for a certain number of times, and use a gray card to compare, and evaluate the degree of color sticking on the white cotton cloth, to check the dyeing of the fabric sample or the stability of the surface coating, and provide reference data for materials evaluation and selection. This instrument is suitable for yarn, dyed yarn, printed and dyed textiles and all substances on or in toy products.

Operating steps:

Sample preparation

1. Samples and standard friction small whitecloth should be conditioned in a constant temperature and humidity environment.

2. If the sample has multiple colors, all colors must be rubbed.

3. If the area of ​​each color is large enough, it should be sampled separately.

4. Cut out the sample, rub dry and wet respectively, making sure all colors are rubbed in.

5. If the front and back of the sample are made of different materials and colors, the color fastness to rubbing should be tested on both sides.

6. Dry and wet rub resistance should not be repeated on the same part of the sample.

Wipe dry

1. Lay the specimen flat on the friction instrument covered with sandpaper, align the longitudinal direction of the specimen with the stroke direction of the instrument, and fix the specimen in the The clamping plate must be flat.

2. Attach the standard friction small white cloth to the friction collarup, clamp it with a spring clip and lightly place the friction head on the sample;

3. Make sure the test The sample does not slip or wrinkle;

4. Place the friction head on the sample. Turn on the power and turn on the POWER button. Set the number of tests.

5. Press START to begin testing. When the number of tests reaches the set value, the instrument will stop automatically.

6. Remove the standard white cotton cloth with rubbing and use the color chart for comparison and evaluation.

Wet Rub

1. Soak a standard white rubbing cloth in distilled water*;

2. Take it out and squeeze it into filter paper to ensure dry moisture content;

3. The rest of the steps are the same as the dry friction test steps above;

Result processing

1. Use transparent glue for assessment Lightly stick Remove loose lint from the white cloth.

2. Use three layers of unusedt white cleaning cloth under the white cleaning cloth you want to evaluate, and refer to the standard coloring grayscale to evaluate the coloring level of the white cleaning cloth.

Test report

1. Report the standard method

2. Report the results of dry rubbing and wet rubbing, respectively.

3. If the sample has been pre- or post-treated, state the treatment method.
