Question on concentration of pigment in textile fibers

[NLO]

Hi!

I am looking for some help with understanding what are the "usual" values for concentration of pigments in textile fibers. Would appreciate any help, links, comments..

I did some search on the Internet. The resource that I was able to find is this:
http://books.google.com/books?id=yS...ts=p43ArNpBND&sig=r3lo02jzc6v7kgjzTYEJeLAAAZo

It says:
... reflection curves obtained for a yarn made with 0.125%, 0.375% and 1.25% of a 25% concentrate of Yellow 17 in polypropylene...

Does this mean that the concentration of pigment in yarn is 0.125%, 0.375% and 1.25%?

Thank you!

Hi!

Thank you for your question. The concentration of pigments in textile fibers can vary depending on the type of fiber, dyeing method, and desired color intensity. Generally, the concentration of pigments in yarn can range from 0.1% to 2% by weight.

The resource you found on Google Books is discussing the reflection curves for a yarn made with different concentrations of a specific pigment, Yellow 17. The concentrations mentioned (0.125%, 0.375%, and 1.25%) refer to the percentage of the pigment in the yarn, not the overall concentration of pigments in textile fibers.

I would recommend consulting scientific journals and textbooks on textile dyeing and coloration for more specific and comprehensive information on the usual values for concentration of pigments in textile fibers. Additionally, you can also reach out to textile dye manufacturers for their recommended concentrations for different pigments and fibers.

I hope this helps and feel free to ask any further questions. Best of luck with your research!

Hello there,

The concentration of pigment in textile fibers can vary depending on the type of pigment, the desired color intensity, and the type of fiber being used. However, a common range for pigment concentration in textile fibers is between 0.1% to 3%.

In the resource you found, the concentration of the pigment Yellow 17 in the polypropylene yarn is 0.125%, 0.375%, and 1.25%. This means that for each 100 grams of yarn, there is 0.125 grams, 0.375 grams, and 1.25 grams of Yellow 17 pigment.

I hope this helps! If you need more information or have further questions, please let me know.
