G238D JIS Friction Color Fastness Tester is mainly used for evaluating and judging the color fastness to friction of dyed fiber textiles,in accordance with the Japanese JIS series standards.

　　Testing principle:

　　Tie dry or wet white cotton cloth onto the surface of the friction head of this machine,and use the prescribed method to rub the sample against the friction white cotton cloth.Compare the degree of staining of the friction white cotton cloth with the gray scale of the staining rating,and evaluate the level of dyeing friction firmness.

　　Testing standards:

　　JIS L0801-2004 General rules for color fastness test methods;

　　JIS L0823,JIS L1006;

　　JIS L1084-2009 Test methods for flocked fabrics;

　　JIS K6328-1999 Test methods for rubber coated fabrics;

　　JIS P8136 Method for determining the wear resistance of paperboard;

　　JIS L0849-2004 Type II(vibration mode)test method for color fastness to friction.

　　Technical parameters:

　　1.Arc test bench(Japanese standard:shape proposed by the Academic Revitalization Association)

　　2.Type:Learning vibration form

　　3.Number of test sample digits:6 digits

　　4.Sample table:curved table with a surface radius of 200mm

　　5.Shape of the friction head:curved,with a surface radius of 45mm

　　6.Test load:2N

　　7.Head movement:100mm

　　8.Reciprocating speed:30 times/min

　　9.Pre set frequency:1 to 9999 times,10 to 99990 times,100 to 999900 times in three levels

　　Operation:

　　1.Firstly,prepare the accessories and test samples;

　　2.Install the sample on the test bench;

　　3.Install white cotton cloth on the friction head;

　　4.Lift the connecting rod that will not be tested temporarily;

　　5.Start the instrument and set the number of operating cycles;

　　6.Repeated friction between the sample and white cotton cloth;

　　7.Automatically stop transmission when the set number of turns is reached;

　　8.Remove the white cotton cloth and sample;

　　9.Turn off the instrument and end the experiment;

　　10.At the end of the experiment,take the sample for analysis and comparison to evaluate the color fastness of the sample after friction testing.

　　Advantages and characteristics:

　　1.Have a strong after-sales service team;

　　2.Able to handle various issues in a timely and fast manner,relieving customers of any worries they may have;

　　3.Complete spare parts to solve the problem of long lead times when ordering spare parts;

　　4.Keep up with industry standards updates and provide textile testing instruments that meet the new standards in a timely manner.
