Importance of dye temperature

[ken_the_stp]

Reading this forum I see a lot of ppl stating the correct temperature for the AL dye. I can not recall anyone addressing why it should be at a set temperature.

I think there could be tremendous benefits for all who read if we got into decused the whys of dye temperature in detail.

140 Is usually a key temperature...some dyes do fine without heating...others will not work at all without heat

and why is 140 degrees a good temperature? dose open the pores up? why dose temperature affect the dyeing process.

[destroyer125]

surpassing those temperatures will actually begin the sealing process in your dye tank...which is not good...the hotter the dye is...the easier it will penetrate the pores..colors like green and blue and red I have trouble getting to take without heat....other colors like orange and lime green...ive never heated

ken_the_stp,
The optimum recommended temperature of 140* comes from the manufacturer of the dyes. They make and test the dyes so that they can stand behind what they sell. That is also where the optimum Ph levels come from. The reason for it working better at elevated temps has more to do with solution color saturation than any effects on the pores. The reason for not going above 150* is the pores first start to close and limit or totally hinder any dye entering the pores.
Hope this helps.
