Quality Control

Criteria
During development all CFT testmaterials are subject to two types of tests; A detergent comparison test, to detect the Discriminative Power of the product, and a dosage/response test, to test the reproducibility. Obviously we aim to create a testmaterial with a high Discriminative Power and high reproducibility.
During production and processing we also check the within-batch variability. Our standard rule to accept 2% point variation within one side of the fabric. Due to several reasons it can be that the two sides vary more than 2% point from each other, the darkest side is then always marked as front. For very dark testmaterials we only accept 1% point of variation. All the material outside these boundaries will be disgarded.

Batch to Batch Control
C.F.T. soiled testmaterials are always subjected to a strict quality control before delivery. The main criterion here is the response to certain treatments within a wide range of concentrations. The most recent results of these Quality Control tests are published on our website. You can download the QC-sheets with the following link: Download a QC-Sheet Below you can see an example of such a Quality Control Chart. Except for the response, it gives the Ru = unsoiled reflectance, and Rs = soiled reflectance values.

qc1
The necessary tests are being performed by means of a 7 kg Wascator FOMLAB machine, in which the main wash is carried out in 1 litre polyethylene bottles, each filled with 500 ml of stock solution in an increasing concentration. At the end of the main wash, the bottles are pored empty into the machine and subsequently a normal cold rinse cycle is being carried out. After the rinse cycle, the washed pieces of test fabric are dried, in most cases ironed, and next the reflectance is measured at 460nm.
The Rs values are kept as constant as possible. Nevertheless, variations may occur due to batch-to-batch variations in the natural raw materials.

Measuring of soiled testmaterials
Testmaterials are best judged by reflectometry as mentioned above or by chemical analysis. An objective assessment, using a spectrophotometer, yields two sets of data:

 

  • The initial, soiled reflectance: R-soiled (Rs)
  • The reflectance of the washed cloths: R-washed (Rw)

From these values, the difference in reflectance – ∆ (delta) R can be calculated (∆R=Rw-Rs) and used as a measure of soil removal. Sometimes the unsoiled reflectance Ru is used to calculate the absolute soil removal.

 

Industry Standards

Protocols
A lot of testing is being done in the industry according to all kinds of standard protocols. Especially in the machine testing industry there is a high level of standardization of tests; Such as the IEC 60456 protocol for machine testing and awarding Energy labels. This international standard is used in Europe, a derivative is being used in the USA under AHAM standard and in Australia and in other parts of the Southern hemisphere the AS/NZS Standard is applied to award the EnergyRating.There have been numerous of test methods which were used for detergent testing. The last few years we have seen more movement towards standardization and consensus. The two main exponents from that are the AISE-protocol and the Ecolabel-standard. And these two standards are also moving closer together.
Especially the AISE-protocol is a base standard that means it leaves a lot of room to add other stains or testmaterials as well, so that you can better incorporate the protocol into your own protocols. Both protocols incorporate a section on colour management as well.

Testmaterials for Standard Tests
On our website you can soon find extensive lists per standard which testmaterials and consumables you would need for which standard test. Of course all these items can be purchased through CFT. Some examples:

  • EnergyRating tests AS/NZS: AS-09 test swatches
  • AISE Soil removal tests: Strip-AISE A (swatches) + Strip-AISE B (stains) or both combined on Mon-AISE SoilsEq
  • EnergyLabel tests IEC 60456: IEC 60456 4th edition Strips
  • AHAM test: AHAM HLW-1 / IEC 60456 5th edition Strips
  • Ecolabel tests: New monitor with 12x12cm soiled swatches
  • AISE colour care test: 40 colours of AISE Dye Set
  • AISE colour transfer test: E-130, E-131, E-132, E-134

For dishwash tests the most important standard is the IkW standard test protocol. This requires a lot of testmaterial preparation in-house. CFT has developed her own method using standardized soiled tiles which are commercially available and can form a welcome addition to IkW test.

Other consumables for Standard Tests
Next to the choice of testmaterial other consumables are needed to perform laundry tests as well. For instance the ballast load to which the tracer stains and testmaterials are added. A consistent and reproducible load is important, because it can have a significant effect on the test results. Often a standardized soil ballast load is added to the clean ballast load items to mimic a soiled consumer wash load. Of course you will need the formulas for your tests and it is recommended or obliged to use a standard reference detergent as well. All these consumables can of course be bought through CFT as well.

Prices

Introduction:
We are proud to inform you that with few exceptions all our prices have remained unchanged. A minor percentage has been increased but a for a larger group we have even lowered the prices, due to some improvements in the efficiency in production of these products. As always this pricelist also include products produced by WFK Testgewebe, Swissatest and Testfabrics Inc., which you can buy through CFT. CFT is also an official distributor of Warwick Equest produced stains, prices of these products are available at request. Next to the listed products we can also prepare all kinds of custom made or other exclusive products.

Products – Standardized Testmaterials – Artificial Soils

Artificial Soils (AS)

The AS-Series’ products were the 13 products which CFT started their business with in 1989. These testmaterials can be categorized as ‘technical’ testmaterials. Not so much consumer realistic but designed to show well discriminating and reliable results.
Ten years later after CFT had developed a large number of other testmaterials in the Consumer Soils Series (CS-Series), the article coding was changed. The Artificial Soil Products like AS-01, are now known as C-01 etc. This was done to make sure the first letter of the product code corresponds with the substrate material (C-01 for cotton, W-01 for wool, PC-01 for polycotton etc.).

C-01 Mineral oil with carbon black
C-02 Olive Oil with carbon black
C-03 Chocolate milk with carbon black
C-04 Olive oil with chlorophyl
C-05 Blood, milk, ink
C-105 Blood, Milk, slightly tinted
C-06 Pigment, oil, for industrial laundry
C-07 Motor oil with carbon black
C-08 Pigment, oil (above 60C)
C-09 Pigment, oil (below 60C)
C-10 Pigment,oil,milkcontent
C-11 Milk with carbon black
C-12 Pigment, oil, low milk content
C-13 Soot, thickening agent
AS-09 Australian standard
