Description

Features of Crockmeter TF411

1. Accurate test result

The precision slide rail ensures the linear movement of the friction rod and the friction finger, avoiding the uneven staining test result.

2. Both wet and dry rubbing testing can be performed.

3. Advantageous test sets

An enormous-sized specimen exerts even pressure on the sample,

getting rid of the wrinkles when rubbing.

4. Meet strict standards

Parts such as switches, buttons, and counting meters are from the US

and Japan. They meet strict test standards and have stable performance.

Easy to operate

Easy lift design makes it easy to change either Abradants or Specimens.

The unique Handle design makes this crock meter portable and friendly to female operators.

5. Long Service life

The cover is shielded to prevent dust and other debris from falling into the instrument, prolonging the service life.

6. The load weight can be selected.

Regularly, the reciprocating load arm is weighted to provide a constant 9N load on the sample at all times, and TESTEX can design other weights if you need them.

TF411 is equipped with a mechanical counter that keeps track of completed cycles.

Test Principle of Crockmeter TF411

The rubbing head (usually weighs 9N) runs with a standard speed in the friction cloth specimen, to do the standard length of reciprocal linear motion, after reaching the set number of times, the Crockmeter automatically stops running. Then use the gray sample card to assess the staining of the friction cloth, so as to assess the rubbing color fastness of the sample.

Application of Crockmeter TF411

The Crockmeter also named rubbing fastness tester, is mainly used in cotton, wool, hemp, silk, knitting, printing, and dyeing industries, the determination of various types of fabric color resistance to dry, wet friction color fastness.

Moreover, the Crockmeter rubbing fastness tester can apply to textiles made from all fibers in the form of yarn or fabric whether they are in the process of dyeing, printing, or coloring. However, it is unwise to use the Crockmeter for carpets or for prints. Because their singling out of areas may be too small to apply this method. Most importantly, we need to carry out the Crockmeter test before or after some treatments, such as washing, dry cleaning, washing, dry cleaning, shrinkage, ironing, finishing, and other processes about textiles. Otherwise, they may affect the degree of color transfer from a material, making it poor.

Besides, the Crockmeter is equipped with an electronic counter with a handle set on the top to take it easy. And it has a piece of sandpaper set under the test sample. Therefore, it is possible to fix the sample during the test, making the rubbing Color Fastness test repeatable. With the aid of a stable slide, the instrument can offer you even and precise testing results.

Except for the rubbing fastness tester, other color fastness equipment including the washing fastness tester, and light fastness tester, can check on this page by clicking here.

The significance of the color fastness resistance

As we can see, it is easy for the color of one piece of cloth to change and transfer to another cloth in the process of manufacturing, wearing, storage, etc., due to the rubbing. What is worst, wearing cloth with poor color fastness, not only will stain other light-colored clothing, affecting the beauty but also surface dyes will be easily transferred to the skin due to the rubbing. As a result, the skin will absorb the dye, causing allergies to the skin, or doing harm to the human body to some extent. Therefore, it is of great importance to test the color fastness resistance and improve it.

Terminology


Dyeing color fastness: the resistance to transferring the color or stained color to other materials. And the color fading or the transfer may occur during the processing, testing, storage, or usage.


Friction Decolorization: The transfer of color from one material to another material by rubbing.



Test Specification


This method is used to measure the degree of color transfer from colored textile surfaces to other textile surfaces under the effect of friction. It applies to dyed fibers, printed fabrics, or other colored yarns or fabrics. The dry and wet white cotton cloth is used as a friction medium.



Sample Preparation


Crocking Cloth: This is a white unbleached, undyed cotton lawn material


Fabric to be Tested: The sample need not be cut to any specific size as long as an increased portion covers the metallic mounting plate.


Two specimens are required for dry testing and two for wet testing.


The two specimens for each must be such that one is assessed with the long direction parallel to the warp and another parallel to the weft. The wet test must be made with fresh dry samples and crocking cloths which have been wetted with water and squeezed to 100% take up (i.e. 10 grams of fabric is increased to 20 gm's of fabric plus water).



Test Procedure


1 Hang the Loading Piece on the Hang Pin. Mount one piece of crocking cloth onto the Rubbing Finger using the clip provided.


2 Mount the specimen on the base plate. Press the button on the counter to clear the counter to zero. Start the test by shaking the handle clockwise.


3 Take out the white cotton cloth and compare it with the colored grey card or AATCC color card to evaluate the color degree of the white cotton cloth.



Test Principle


Textiles will often rub with other objects when they are used. Sometimes, they are rubbed in wet conditions and even stained with other objects if the dye fails to own good dye fastness. Therefore, there should be some specified requirements for the rubbing color fastness.


The rubbing color fastness refers to the resistance to color fading of fabrics in friction for a long time with each other or other objects to measure its impact on the fabric color fastness.



How to rate the sample?


1 The rating should be accurate to 0.1 level if multiple samples are measured.


2 The white clothes with three layers should be lined under the test cloth when rating.


3 A color transfer ruler or stained gray card should be prepared to evaluate the amount of color transfer to the rubbing cloth of the measurement sample


4 A stained gray card or a 9-step AATCC color transfer card can be used to evaluate the wet and dry rubbing fastness with



How to test the dry and wet friction fastness of fabric?


Dry rubbing
Fix the specimen on the friction head of the friction fastness test machine, so that the warp direction of the rubbing cloth is the same as the running direction of the friction head. In the length direction of the dry rubbing specimen, the machine is switched on with a reciprocating dynamic range of 100 mm and a vertical pressure of 9 N on the friction head, respectively detecting the longitudinal and latitudinal direction of the specimen. Specimen and friction cloth in the standard atmosphere to adjust the wet, the test should be carried out in the standard atmosphere.

Wet friction
Wet friction specimens must be wetted with tertiary water, removed, and placed on a dripping net to drip evenly, or squeezed using a liquid roller to achieve a water content of 95% to 105%. Other operations are essentially the same as dry friction testing. After the wet rubbing test, the wet rubbing cloth is left to dry at room temperature.

Report Content


Indicate whether dry or wet friction and write out the evaluation results. Write down whether to use a stained gray card or a colored card in the rating process and describe the treatment of the sample.



Caution


1 The colour fastness to rubbing test should be carried out on the front side of the specimen. If any dyed fibres are brought out and left on the rubbing cloth, they must be removed with a brush.

2 The lining fabric should be stored in a sealed, light-proof, and dry place to avoid contamination, moisture, and yellowing.

3 Before testing, the rubbing surface of the friction head should be carefully checked to ensure that it is smooth and uneven.

4 The rubbing fabric should not be loosened when fixed to the friction head. After fixing, the rubbing head should be carefully placed on the specimen to avoid accidentally increasing the degree of staining.
