Digital Rubbing Fastness Tester

Digital Crock Meter: Working Principle, Testing Procedure, Manual & Price Guide

Colour quality is an important factor in textile, garment and footwear manufacturing. A fabric may look attractive when it is new, but if its colour transfers onto another surface during rubbing, it can affect product quality and customer satisfaction. This is why manufacturers and quality control laboratories perform colour fastness to rubbing tests using a Digital Crock Meter.

A Digital Crock Meter, also known as a Crockmeter or Rubbing Fastness Tester, is used to evaluate how much colour transfers from a textile surface onto a standard rubbing cloth under controlled conditions. It helps textile manufacturers, garment exporters and testing laboratories assess the rubbing fastness of fabrics under dry and wet conditions.

For manufacturers looking for a reliable Digital Crock Meter in India, understanding its working principle, testing procedure, applicable standards and price factors is important before purchasing the equipment.

1. What Is a Digital Crock Meter?

A Digital Crock Meter is a textile testing instrument used to determine the colour fastness of fabrics against rubbing. It works by rubbing a standard white cotton crocking cloth against a prepared fabric specimen under controlled testing conditions.

The machine produces a repeated rubbing movement over a specified distance while maintaining the required pressure on the test specimen.

After completing the test, the rubbing cloth is examined for colour staining. The staining is generally evaluated using an appropriate Grey Scale to assess the fabric's resistance to colour transfer.

A digital or motorised Crockmeter uses a controlled drive mechanism and a digital counter to manage and monitor the rubbing cycles, reducing variations associated with manual operation.

Common testing applications include:

• Dyed and printed fabrics
• Cotton and blended textiles
• Knitted and woven fabrics
• Denim and apparel materials
• pholstery and furnishing fabrics
• Garments and footwear materials

2. How Does a Digital Crock Meter Work?

The working principle of a Digital Crock Meter is based on controlled friction between a test specimen and a standard rubbing cloth.

The fabric sample is secured on the testing platform. A rubbing finger fitted with standard white crocking cloth moves repeatedly over the specimen under a specified load.

The rubbing action causes any loosely attached or transferable colour to move from the specimen onto the white cloth.

The test is performed under dry or wet conditions, depending on the testing requirement.

The basic working process involves:

1. Preparing the fabric specimen according to the applicable test method.
2. Fixing the specimen securely on the testing platform.
3. Attaching the standard crocking cloth to the rubbing finger.
4. Applying the specified testing load.
5. Setting the required number of rubbing cycles on the digital counter.
6. Operating the machine to complete the rubbing movement.
7. Removing and examining the crocking cloth.
8. Evaluating the staining using the relevant Grey Scale.

This process helps laboratories assess the resistance of textile materials to colour transfer during everyday use and handling.

3. Dry Rubbing Test vs Wet Rubbing Test

A Crockmeter is commonly used for two important types of colour fastness testing.

Dry rubbing test: A dry crocking cloth is rubbed against the fabric to determine whether colour transfers under dry friction.

Wet rubbing test: A crocking cloth is prepared with the moisture level specified by the applicable test method. It is then rubbed against the specimen to evaluate colour transfer under wet conditions.

Both tests are important because a fabric may perform differently under dry and wet rubbing conditions.

4. Digital Crock Meter Testing Procedure

Following a consistent testing procedure is essential for obtaining repeatable results.

Step 1: Prepare the test specimen

Cut the fabric specimen to the dimensions specified in the applicable testing standard. Condition the sample where required.

Step 2: Prepare the rubbing cloth

Take the required standard white crocking cloth. For wet testing, prepare the cloth according to the moisture requirements of the selected test method.

Step 3: Mount the specimen

Place the fabric on the testing platform and secure it properly using the specimen holder.

Step 4: Attach the crocking cloth

Fix the white rubbing cloth onto the rubbing finger using the appropriate holding arrangement.

Step 5: Set the testing parameters

Set the required number of rubbing cycles using the digital counter. Confirm that the appropriate load and test configuration are selected.

Step 6: Start the test

Operate the Digital Crock Meter. The rubbing finger moves repeatedly across the fabric specimen.

Step 7: Evaluate the result

Remove the crocking cloth and compare the transferred colour with the appropriate Grey Scale for staining.

The final assessment should follow the applicable standard and laboratory procedure.

5. Digital Crock Meter Manual: How to Operate the Machine

A Digital Crock Meter manual provides operating instructions, testing precautions, machine maintenance information and guidance for obtaining consistent results.

Although the exact operating controls may differ between machine models, the following general guidelines are useful:

Important operating precautions:

• Always use suitable standard crocking cloth.
• Avoid loose specimen mounting.
• Check the rubbing finger and sample holder before testing.
• Do not change testing loads without checking the applicable method.
• Keep the instrument clean after use.
• Follow the manufacturer's operating manual for model-specific instructions

For laboratory buyers, it is advisable to request the operating manual, recommended accessories and technical support when purchasing a new Crockmeter.

6. International Standards for Crockmeter Testing

A Digital Crock Meter is commonly used for colour fastness to rubbing tests according to recognised textile testing methods.

Some relevant standards include:

The exact test configuration, specimen preparation, rubbing conditions and evaluation procedure should be selected according to the applicable standard and its current edition.

Laboratories should verify the required standard before purchasing testing equipment.

7. Important Features to Consider When Buying a Digital Crock Meter

Selecting the right Crockmeter depends on the testing requirements of your laboratory or manufacturing facility.

Consider the following features:

• Digital counter: Helps set and monitor the required rubbing cycles.
• Controlled rubbing movements: Supports consistent testing.
• Specified rubbing load: Ensure testing is performed under the required pressure.
• Rubbing finger: Its diameterr and configuration should suit the selected test method.
• Dry and wet testing: Should suppport the required testing applications.
• Construction quality: A durable machine body supports regular laboratory use.
• Terchnical support: Availability of operating instructions, accessories and after sales assistance is important.

Before placing an order, compare the machine's specifications with your laboratory's actual testing requirements.

8. Digital Crock Meter Price in India: What Determines the Cost?

The Digital Crock Meter price in India depends on the machine's configuration, construction, automation and supplied accessories.

Online product listings show considerable price variation. For example, publicly listed products include a Digital Crock Meter around ₹32,000 from Texcare and a digital rubbing fastness tester listed around ₹64,999 by Texmart. These are individual advertised prices, not a standard market rate or directly comparable quotations.

The following factors influence the final Crockmeter price:

1. Manual or motorised operation.
2. Digital counter and control system.
3. Construction material and machine design.
4. Rubbing finger and additional testing attachments.
5. Standard accessories and crocking cloth.
6. Calibration documentation, warranty and technical support.
7. Customisation and specific laboratory requirements.

If you are searching for a Crockmeter price, it is advisable to compare the complete machine configuration rather than selecting equipment based only on the initial quoted amount.

Contact the manufacturer with your testing requirements to receive an appropriate quotation.
