Ok, i'm blown away by the high chromas in this dye. I have switched my project for this class to COTTON rather than silk. I am dyeing Silk, Linen and Cotton for my pure colors and have fallen in love with how nice the cotton comes out when finished. I like the Lanaset colors better for silk, so i figured i may try to do something I'd actually use when finished. So cotton it is.

Here's my substrate. 3/2 cotton.

II SEE THE LOUSY WRAPPING ON THE LINEN - I'LL HAVE TO PAY MORE ATTENTION.

High chroma, wait till you see the fuchsia!

The silk does the high chroma part fine but is limited to how dark it will go. Fewer -OH groups or dye sites to bind to.

Interesting how much darker the blue is on the linen.  Is the silk whiter than the linen, does that account for the higher chroma in the DOS 4% yellow?

Busy little superdyer!

Mary,

Since you didn't test the cotton during the commissioning phase I have a few questions for you.

Is 3/2 a perle cotton?  Perle cotton is mercized and scoured.  Mercerized cotton takes the dye differently than unmercerized cotton.  It is more lustrous so it appears darker.  I suspect there is residual alkali from the mercerization in the cotton that effects the whole process.

And the linen is bleached, right?

Mary,

Looking at the pic of the substrate it looks like unmercerized cotton with little brown flecks in it.  The brown flecks indicate that it has not been highly processed.  It also suggests that it might benefit from a scour.

I thought it 3/2 (it's so fat!) but i confirmed upon ordering more today, that it's 5/2 high twist from Henry's Attic - unmercerized. How should I scour? Boil with ? For how long?

Would you suggest I redye the cotton after I scour? Or won't there be that noticeable a difference?

Thanks ; )

I love this color.  I was surprised by the color shift in the 4.0% DOS organza.  I was also surprised when the .25% DOS paj was not level as all the other samples have been.  I will redye this one, paying special attention to it.  Perhaps the small amount of dye struck quickly and needs to be lifted a lot???

Here are my chips:

You need to test with the boring beige.  Dye two skeins one as is and one scoured to see if there is a difference.  If there is no difference don't bother to scour.

Scour for cotton: for a 5g skein, 500mL water, 5 g soda ash, a drop or two of Synthrapol; boil for 15 min. If the water is very brown you can repeat.

Rinse at least twice to get rid of the soda ash.

Anne,

Getting level dyeing with a pale color is always a challenge because there is so little dye..  Techniques that I use:

    Don't add all the salt at once.  Divide in 2 or 3 portions add one, agitate wait 5 min. then add the next portion until all has been added.

    Pay more attention to aggitation at the begining of each phase.

Thanks for the scour info, When i do a test dye - would you recommend a darker or lighter color?

thank you.

Here are my chips for Golden Yellow.  These are luscious colors.

Thank you for the help on the levelness in the pale colors.

Here are my Blue F-41 chips.  Either my eyes are color fatigued, or the organza didn't shift on this color nearly as much as the others.

Karren, would you care to describe in Munsell notation just what "brown" water is to you? (just kidding)  I do believe i need to scour - I'm going to make a big old skein and scour that because the little ones will just get tangly. Glad we have 2 weeks for this assignment!

OK for the math - 5g soda ash for 5g skein. 1 lb of yarn = 453g. So should i assume, i'll be puttling 453g of soda ash in the pot along with 45,300ml of water? (or is it 12 gallons?) can i do this in my washing machine (front loader, low water volumes)? i've never scoured...need direction -- or maybe i just dye the skeins unscoured and leave it at that!

Here's my "brown" water and the "orbitz" yarn skein difference. Don't think it's going to require a 2nd bath, do you?

Looks like once will do.  I can see in the photo, with out Munsell Notation, how much whiter the scoured skein is.

Scour: Water to allow the skein to move freely, in this case the more the better. Estimate volume, add 1% of the volume in soda ash.  1% x 500mL= 0.01 x 500g= 5g of soda ash.  Enough detergent to make a bit of foam on the surface-- too much and you'll be rinsing forever.

If you scour in the big skein you have to dry it to reskein....  If you scour the sample skeins they can go directly from the rinse into the dyebath; no drying, no soaking.

OK, makes sense to me. So if i get all my mini skeins in a big pot - just enough water to let them move freely, how much soda ash should i figure? is it still 5g soda ash to 5g skein? So if i scour 25 skeins in a big old pot, should i add 25g of soda ash?

sorry for being so ignorant on such matters. thanks for your help.

In a big old pot, estimate the amount of water you have.   For each quart or liter  add 10g of soda ash. If you use 2 gallons of water that is 8 quarts so add 80g of soda ash.  Dissolve before adding the goods.  Use an inert pot ( SS, enamel, glass) otherwise you could be adding metal ions to the goods  :(.

Looking good Anne.  You've been a busy beaver.
