ICI Pilling and Snagging Tester is used to determine the surface fuzzes and pilling properties of both woven and knitted materials. grade.
 
 

ICI pilling snagging tester operation instruction:

 
The 105mm × 105mm samples are put into the test box, the rotation of the impeller, the cork lining wall of the shelf box continuous random friction, the timer will be set to the specified time, after reaching the set time sound hold tight, prompting the end of the test. The test chamber will be injected with compressed air to enhance the flip during the test, the air pressure is adjustable.
 

ICI pilling snagging tester's 4 main structures:

 
1. the movement of the grinding head:
 
ICI pilling snagging tester in the speed of the abrasive head trajectory, directly affects the effect of friction between the specimen and the abrasive. This instrument adopts JX 07 capacitor motor, the speed is reduced by a worm gear installed in the gearbox, the speed ratio is 1: Han, so that the grinding head obtains a speed of 60 revolutions per minute. The size of the trajectory. The trajectory of this apparatus selected 40 mm diameter circle (countless composite circle) when toggling the forward and reverse switch, can be obtained clockwise or counterclockwise trajectory.

Test that: this circular motion trajectory, with symmetry, so the specimen does not have the provisions of the latitude and longitude, the direction of the specimen clamp sample, there are no special requirements and to ensure the uniformity of friction movement at all points of Lee, etc., in addition, we are in the structural design, the use of brushes in the bottom, the specimen on the top, so that the abrasive chips and debris will not stay on the friction specimen, and affect the test results.
 
2. Specimen pressure:
 
The size of the specimen under pressure, is the second factor related to the form of hair pilling, the apparatus adopts direct pressure method, the mechanism is simple and effective pressure, the grinding head is equipped with five hand grips (i.e., pressure hammer) according to the different varieties of raw materials, according to the provisions of the choice of the pressure range of 500 ~ 800 grams of test hair, so that the specimen and the position of the brush corresponding to the different pressure, so that the specimen obtained 13 ~ 21 g / cm2 pressure. square centimeter of pressure. When continuing the pilling test, simply loosen the positioning screw on the side of the abrasive holder, push the holder, move the brush away from the specimen, so that the specimen and the pilling abrasive maintain the corresponding position, and then fix the positioning screw. Therefore, we hope to have a large pressure and the formation of "balling", most of which occurs under light friction, so the pressure of pressure should be light to master.
 
 
3. choice of abrasive:
 
ICI pilling snagging tester in the pilling test, the use of 2201 pure wool wada tweed lined with 10 mm thick foam for the abrasive material when pilling using a certain size of nylon wire brush, as these two abrasives are easy to obtain and long life, to create the conditions for the stability of the test data brushes selected materials hair height density as well as the old and new brushes are The length of the bristles on the brush, which means the test force, the size of the deflection of the bristles, in general: short and strong bristles, long and soft bristles, the formation of a great difference in the effect of bristles, such as bristles longer than 25 mm, the end of the bristles easy to be bent, affecting the effect of bristles, reducing the life of the brush if the bristles are too short when less than 10 mm, the effect is violent and may even break the sample, after several tests that the length of the bristles The new brush should be "purified" before the official use of the machine, under the condition of light pressure, and the specimen rubbed in advance for a certain period of time, so as to ensure the stability of the normal test data when the normal use of 2 to 3 years later, the brush began to have the aging trend, affecting the effect of hair, should be The brush should be replaced with the same specifications.
 
4. Counting and self-stopping:
 
Counting and self-stopping is an indispensable part of ICI pilling snagging tester, we use JDM a 41 four-digit electromagnetic counter for the accumulation of the number of tests. With a fixed value of the signal mechanism. When the number of tests reaches the specified calming value, the instrument automatically stops rotating and the self-stop indicator gives a signal.
