How To Operate Crockmeter With Manual Or Electric The color fading of clothing to rubbing is an annoyance for people, as it directly affectsthe appearance and service life. In order to improve this property, producers have toattach importance to the color fastness of raw materials like textiles or leathers torubbing and master it with the help of an instrument, so the crockmeter was born to bethis helper. The AATCC Crockmeter provides a quick and accurate method to determine the amount of color transferred from textile materials (such as fabric, carpeting, yarn and leather) to other surfaces by rubbing. Crockmeter machine with manual and electric to test the color fastness of textiles to dry or wet rubbing. Also named rubbing fastness tester.In the crocking test, a reliable Crockmeter plays a vital role in the repeatable and reproducible results. Manual Crockmeter Test Procedure 1. Remove the metal sample holder and place the specimen on the plate sticking it  to the pieces of tape. Replace the metal sample holder. 2. Mount the crocking cloth onto the crocking pin, using the clip to secure the cloth. 3. Lower the rubbing head onto the fabric specimen and perform the required number of rubs by turning the handle. 4. When the requisite number of rubs has been completed lift the rubbing head and remove the sample and crocking cloth. 5. If a wet fabric has been tested allow the crocking cloth to dry at room temperature. Electric Crockmeter Test Procedure 1. Pull out the bolt and lift up the friction head,Twist the bar and take out the platen 2. Place the sample on a platform and Cover the pressure plate,Install the depression bar and lock. 3. Fix the friction cloth on the friction head with an iron ring. 4. set the test times after power switch, click s to start the test. Different from the manual crockmeter, the reciprocating number of electric corckmeter can be preset on the counter and run automatically up to the end point,which can save much labor.

This Bally resistance flexing tester is used to determine the resistance of a material to cracking or other types of falure at flexing creases.The method is applicable to all flexible materials and in particular leathers, coated fabrics and textiles used in footwear uppers. Bally leather flexing tester test specimen is folded in half then one end is secured in a clamp.The test specimen is then turned inside out andthe free end secured in a second clamp at 90 degrees to the first.The first clamp is repeatedly oscillated through a fied angle at a defined ratecausing the test specimen to flex.At set intervals the number of fexing cycles is recorded and the damage to the test specimen is visually assessed. The bally flex test can be carried out with wet or dry test specimens at ambient. 1. Dry test 1.Clamp the specimen: 1.1 Twiddle the back button of the machine,and adjust the upper jig to the horizontal position. 1.2 Fold up the specimen from the middle in the length direction, making the testing side inwards and the edge aligned, as fig.5 shows. 1.3 Fixed the upper jig and lower jig and Loosen the screw, then put one end of the specimen into the upper jig to make the folding line flush with the bottom line of the upper jig. Then lock the set screws when the specimen reaches the set crews of the upper jig. 1.4 Fold down the other end of the specimen, cover the folding ling and keep vertical, as FIG 6 shows. 1.5 Then vertically insert the bottom of the specimen into the lower jig(90 degree)and keep the folding line vertical.Before insertion gently pull the specimen and lock the set screws (just straight the specimen, and don't have to exert a greater force) 1.6 After Clamping the specimen, turn the back knob to adjust the upper jig to the maximum bending angle, and the bending angle should be 22.5±0.5. 2. Wet test 2.1 Turn up the reverse side(not used for testing) of the specimen on the table, draw distilled water to the reverse side with the straw and then roll on it with glass rod to make water infiltrate the specimen edge within 5mm. And the absorption lasts about 1-2 minutes. 2.2 The bally flex tester for leather materials operation method is in accordance with the dry test procedure. 3. Attention 1. In case of looseness while bally test, confirm whether the set screws are locked after fixing the specimen. 2. Don't lock the screws too tight when clamping the specimen, so as to avoid damaging the specimen while bending.
