Dyes must meet industry and product specific measurements in order to be approved. A spectrophotometer is an analytical instrument used to test dye to ensure it meets criteria.
Characteristics of fabric dye analysis include identifying the type of dye used, determining dye concentration, assessing dye fastness, and detecting any impurities or adulterants in the dye. Analytical techniques such as spectrophotometry, chromatography, and microscopy are commonly used for fabric dye analysis.
Hydrochloric acid can be used in the dyeing process as a mordant to help fix the dye to the fabric. However, it is not a dye itself and is not typically used directly as a coloring agent.
One common test for lipids in foods is the Sudan III test. This test involves adding Sudan III dye to a food sample - if lipids are present, the dye will bind to them and turn the sample a red color. Another method is the iodine test, where iodine reacts with lipids in food and changes color from brown to purple if lipids are present.
Rit dye is made up of combined acids and sodium chloride which makes it dangerous for human skin and hair. Rit dye is basically used for fabric and other materials.
Salt is used in tie dye to help set the dye into the fabric. When fabric is soaked in a salt water solution, it opens up the fibers of the fabric, allowing the dye to penetrate deeper and create more vibrant and lasting colors.

One common test for identifying lipids is the Sudan III test. This test involves adding Sudan III dye to a sample, and if lipids are present, the dye will bind to the lipids and turn the sample red. This test is simple and used in labs to detect the presence of lipids in various substances.
This test is used to measure bilirubin in urine. The product of the reaction between bilirubin and a diazonium salt, in acidic medium is an azo dye, colored pink to violet, depending on the concentation.
Maybe you aware that not all products can be sublimated. For a substrate to be sublimated onto it needs to have specific characteristics. Today we will share you how to choose the right to do digital dye sublimation printing. First, the sublimation blank must be white. Sublimation inks are transparent and add to the colour of the product. That is why the sublimation blank. Both textile and rigid, must have a white background so that the colors of the original design are not altered. Second, if you want to personalize a hard surface, it must be coated with a polyester-based material. Therefore, it is not possible to sublimate items that are not pre-treated. However, there is plenty of sublimation blanks to choose from. If you want to personalise a non-sublimation product, there are sublimation spray coatings that can turn almost any hard surface into a printable one. Third, if you’re going to do sublimation printing on fabric, you can only work on polyester garments or substrates with a polymer coating. Sublimation on cotton is not an easy task, but there are some solutions to apply sublimation on a non-poly fabric and achieve similar results, so don’t try 100% cotton fabric. If you dont know where to buy sublimation material, contact Sublicool, we will provide you all things!
The material used could be made of wool and the dye that can be used is Acid Dyes. In case the material is made of blends of wool and polyester, the dye to be used will be Acid Dye for wool and Disperse Dye for Polyester. In case the material is made of cotton, the dye is Vat Dye and if blends of cotton na polyester, the dye to be used will be Vat Dye and Disperse Dye.

Yes. It's a test to see if the patient is allergic to the contrast or dye before they inject her with it.
For a colorfast tie dye a fiber reactive dye is needed such as Procion Dye from the Dharma Trading Company. Rit dye can be used but is not fiber reactive and not colorfast and the tie dye will fade colors after each wash.
