Which fabrics are the best to use for tie dye?

if tie dye a shirt made of cotton is the best to use because the negative charge in the shirt ( cotton, silk, etc.) will make the color more absorbent.
 * __ Hypothesis __**

Q) Why to use 100% cotton or natural fiber fabrics? A) imitated natural fabric or man-made materials do not bond to the dye. Think of it like plastic – dye will not stick fast enough to the fibers in plastic.

Q) What is the science behind tie dye? A) The dyes are fiber-reactive, which means a chemical reaction takes place between the dye and the fabric molecules. The dye bonds with the cotton and becomes part of the fabric. That is why the dyes are so permanent and vibrant even after several washing.

ACTIVITY TIME:

This activity will take two days to complete. The first day will take the majority of time. Allow at least an hour or two for the prep, tying and dying. For the preparation – allow about 20-30 minutes to prepare the mixtures, dye and allow for the shirts to soak. Depending on how many shirts or fabrics you decide to do, allow about 10-15 minutes to tie about five shirts. Again, depending on how many fabrics you are dying, allow about 10 minutes per shirt or fabric to dye. You don't want to go too fast squeezing the dye on the fabric, and make sure you are thorough. The second day will be much quicker. Allow about 20-30 minutes to unwrap all the shirts and get them washing.

__//**types to the product shirt in**//__
> > Apply dye to fabric, rotating tube as necessary to saturate fabric. > > Bind spiral with 3 to 4 rubber bands, overlapping rubber bands to create 6 to 8 wedge shapes. Then apply color.
 * //__**yin yang**__// __**-**__You flaten the shirt. Grab a the from the top left shoulder and grab it up. then put a ruer band around it. Then do the same to the bottom right coner. then you make a line with color dye. Then you can chose two differnt color from each other and not the dye you used for the line. Then you start dyeing
 * __//**Shibori**//__ - Roll fabric around a nonabsorbent tube such as a PVC pipe. Tightly scrunch both ends of fabric toward center and secure ends with rubber bands.
 * __//**Spiral**//__ - Pinch fabric at the center of where your spiral will start. Twist until all fabric is in a spiral shape.

100% Cotton seems to be able the best for the color because its the legit fabric. Cotton is the most used fabric for shirts. imitated natural fabric or man-made materials do not bond to the dye. just like plastic – dye will not stick fast enough to the fibers in plastic. A good quality, lightweight cotton is one of the most breath able fabrics around so it will allow a little airflow for dying out the dampness. Aslo, cotton is a natural friber, so it absorbs moisture, rather than repelling it.

__//**Journal 2**//__ Silk is a protein filament secretion much like hair - rather than a cellulose plant fiber such as cotton. This is also why silk is proportionately much stronger than cotton (and steel). dyeing silk, it is the best method in terms of color permanence and overall simplicity.
