community of dyers

This question may have been posted before but I am having a bit of difficulty searching for an answer.

I have a beautiful dress that I want to dye a solid color and I want to try to dye as much of it as I possibly can including the sticking.

The dress in question is composed of silk outer shell and polyester lining and crinoline and also the stitching.

I have experience processing with disperse dyes and have had some wonderful results. I also have good results processing silk.

I would like to know if the silk will suffer if I make the disperse dye bath, heat up the water, and then "quickly" dip the dress in this dye bath....and then after rinsing and drying I would process the silk with the acid dye process.

Hello everybody,

I am researching the uses of different dyes but cannot find any chemistry explanation of how disperse dyes work. I understand the science behind the other main dyes but not this one. Can anyone help out?

So - I'm new here and hope someone can help me with an unusual question. I really like working with liquid dyes because I find them much easier to mix together to get the shades I want. However, I'm working on dyeing some polyester gimp braid trim, and the only dye that will dye the braid evenly is iDye Poly (because the braid is mainly polyester w/ some rayon). iDye Poly only comes in powder form, and there are only a few colors, so I was wondering whether it's possible to "create" liquid dyes from the powder dyes -- i.e. dissolve a small amount of powder iDye with a small amount of water (say, 1/8 the amount one would use to dye 2 pounds of fabric) and store it in a small bottle with a screw-on lid, then simply shake the bottles well and use them like liquid dyes.

Dyeing polyester with disperse dye at 100°C doesn't work all that great—higher temperatures are better, but unreachable at ordinary atmospheric pressure—so we use carrier chemicals such as ProChem's PRO Dye Carrier, Batik Oetoro's PolySol Carrier, or Jacquard Products' iDye Poly Color Intensifier. Terrible smelling stuff, but it improves the color considerably. When I used Jacquard Product's iDye Poly Color Intensifier, the smell was so bad that I now find myself hesitating to use it again inside my house. I've heard the same about other disperse dye carriers purchased from other retailers, including, I think, ProChem, though that was not recently.

Just now, while looking at the MSDS pages for as many of the dye carrier chemicals as I could find, I saw that ProChem's is labeled "Low Odor New and Improved", and, in the MSDS, is described as "odorless". That would be a very nice change!

Yesterday I did some tests with the disperse dye, iDye Poly, in Blue. I bought this dye packet locally, at Texas Art Supply. Lots of stores carry iDye Poly by mail-order, but Texas Art Supply is the only one that carries any polyester dye in their local store. Good for them!

iDye Poly comes in a water-soluble packet. You must not leave it in a damp place, or there will be a mess! It contains enough dye for two to three pounds of fiber. I wanted to dye a size XL cotton/poly t-shirt, along with some test fiber ribbon swatches, total weight 8 ounces (230 grams). Since I did not need the entire packet of dye, I placed it inside a ziplock freezer bag and cut the packet in half with a cheap pair of scissors that I wouldn't mind washing later. Of course, the dye powder went everywhere inside the bag, but the half I was holding in my gloved fingers was intact enough for me to snip off one-third of it, for approximately one-sixth of the 14-gram packet of dye. I did not bother to weigh the dye to confirm the exact quantity....

hi all
i found mwthod to prepare silicone softener

is this the right method to prepare silicone softener for polyester blemds?
