To evaluate colour fastness to sea water, testing of ISO 105 E02 is conducted. ISO 105 E02 is applied on both dyed and printed textile articles which have to be exposed to sea water. In this article, you will learn the importance of ISO 105 E02, colourfastness to sea water, preparation of the testing specimen, preparation of formation of artificial sea water solution in the lab, the complete testing procedure of ISO 105 E02 and evaluation of the results (colourfastness to sea water).
ISO 105 E02 Colour Fastness to Sea Water
Textile articles which have to be exposed to sea water or marine environments such as marine upholstery, swimwear and beach wear are tested in the textile physical testing laboratory against ISO 105 E01, which helps to evaluate the property of colourfastness.
Apparatus and Chemical Required for ISO 105 E02
- Sodium chloride (NaCl)
- Magnesium chloride (MgCl2)
- Distilled water (Grade 3.0)
- Oven
- Perspirometer
- Incubator
- Multifiber
- Petri dish
Preparation of Testing Specimen for ISO 105 E02
- Condition the testing specimen in a conditioning chamber or conditioning maintained controlled temperature and humidity.
- Cut the testing specimen and a multifiber of 40mm x 100 mm or 4 cm x 100 cm and stitch the multifiber and testing specimen from the shorter side following ISO 105-A01.
Preparation of Artificial Sea Water Solution
Take 30 g sodium chloride (NaCl) and 5 g magnesium chloride (MgCl2) in a volumetric flask of 1000 ml. Dissolve both chemicals in grade 3 distilled water and make up the volume to 1000 ml. Your solution is ready to test ISO 105 E02, colourfastness to sea water.
ISO 105 E02 Procedure
- Take artificial sea water solution prepared for ISO 105 E02, colourfastness to sea water in a petri dish.
- Dip the testing specimen stitched with multifiber, in ISO 105 E02 solution at room temperature.
- Remove the testing specimen and keep it on the acrylic ( or Glass ) plate of the perspirometer. The pressure/weight of the perspirometer weight should be 12.5 kPa.
- Keep the perspirometer in the Oven maintained at 37 ± 2degree Celsius for 04 hours.
- After treatment in the oven, dry the testing specimen in an incubator below 60 degrees celsius.
- Asses the colour change of the testing specimen and staining of the multifiber with the help of gray scale of shade change and staining.
Assessment of ISO 105 E02
There are two methods of assessment of ISO 105 E02, colour fastness to sea water known as assessment with the help of spectrophotometer and assessment with the help of grey scale. A spectrophotometer is an instrument which produces the rating of both shade change and staining. Two types of grey scales, the grayscale for color change and the grey scale of staining are used to assess the color change and staining. To assess the change of colour before the test and after the test, use grey scale for shade change & to assess staining on multifiber, use a grey scale of staining.
Safety and Precaution for ISO 105 E02
- Whenever to handle any chemical, you should wear all PPE, including gloves, lab coat and goggles to protect yourself from chemical exposure.
- Always follow Chemical MSDS and chemical SOPs for careful handling.
- Always use calibrated glassware for chemical measurement to get accuracy, because the concentration of the chemical can affect results.
- There should be proper ventilation in the area, where chemicals to be used.
- Always keep a diary with yourself to record testing procedures, and conditions to avoid any misunderstanding and get precise results, which will help in repeatability and reproducibility.
Importance of ISO 105 E02
ISO 105 E02, colourfastness to sea water is very important for different types of textile articles. When dyed or printed articles are exposed to salt and other minerals found in sea water, these minerals can cause colour bleeding or colour fading, which affects the overall appearance of that article. To get rid of such types of issues, ISO 105 E02, colourfastness to sea water is performed in textile physical testing laboratories to evaluate the quality of textile material and assure the quality of the finished product and satisfy the customer. These articles are:
- Swimwear: To evaluate the colour bleeding and fading of the swimwear when exposed to sea water, articles are tested in the lab against artificial sea water solution made in the lab following ISO 105 E02.
- Beach towels: Beach towels are also exposed to sea water. ISO 105 E02 colour fastness to sea water is an important test for beach articles to check the quality of the product before sending it to the customer.
- Marine upholstery: Such type of textile articles are also required to test ISO 105 E02, colourfastness to sea water to assure the quality of upholstery.
- Outdoor textile articles: different outdoor articles such as tents, and backpacks used near the sea were also tested as per ISO 105 E02, colourfastness to sea water test.
Conclusion
Textile industries make many products such as swimwear, beach towels, and marine upholstery which come in contact with sea water. There are different salts and other minerals which cause shade change and colour fading of the exposed article. To get rid of shade change and colour fading, an international testing procedure, known as ISO 105 E02 colour fastness to sea water is applied on such types of textile articles to evaluate and improve the quality of the product. Different types of chemicals and laboratory instruments are used to perform ISO 105 E02, colourfastness to sea water. This is the method, which assures the quality of the product enhances the reputation of the industry and satisfies the customer about the quality of the product.
FAQs:
What is ISO 105 E02?
ISO 105 E02 is an international testing method, used in textile physical testing laboratories to evaluate the colour change and colour fade when exposed to sea water.
Which instrument is used to perform ISO 105 E02, colourfastness to sea water?
Perspirometer is used to perform ISO 105 E02, colourfastness to sea water test.
What are the important chemicals used in ISO 105 E02 colour fastness to sea water?
Sodium chloride (NaCl) and Magnesium chloride (MgCl2) is the important chemical product used in ISO E02, colour fastness to sea water.
How to assess the rating of ISO 105 E02 colour fastness to sea water?
You can assess the rating with the help of a spectrophotometer or grey scales. The gray scale of shade change is used to assess the change of shade before and after the testing and the grey scale for staining is used to assess the rating of the staining of multifiber attached to the testing specimen.
What is the pressure or weight that should be applied on the testing specimen in perspirometer.
12.5 kPa of pressure should be applied on the testing specimen in perspirometer.
