Tie Dye

Transcript: Disperse Dyes -Small, planar bonds Adding water allows polar bonding to improve between the dye and polymer, which affects the color of the product. As the dye is applied under a certain pressure and temperature, thermal agitation loosens the fabric's structure and creates openings for the dye molecules to attach themselves. The chemistry of tie-dye Clairise Bibbs, Juanita Solanilla, Claudia Gutierrez, Julia Ross How it works with wool Conclusion fiber reactive dyes How It Works With Cotton How It Works With Polyester Acid Dyes Using 100% cotton for this type of dye is important because it does not bond to man-made fibers. A process of hand-dyeing fabric, in which sections of the fabric are tightly bound, as with thread, to resist the dye solution, producing a diverse pattern There are many types of dyes but we will be focusing on fiber reactive, disperse, and acid dyes. We will be discussing characteristics of each and how they work. With the different pH levels the dye which allows the hydrogen bonds to form. Mild Acids such as white vinegar are used to lower pH levels and still have a slight acidic reaction. Designed to permanently dye synthetic fibers. With polyester, other dyes do not attach as well and leave the fabric almost the same. Disperse dyes interact with the polyester chains by forming disperse particles. This specific type of dye is the only one insoluble in water and has the smallest molecules. Reacts with animal-based fabrics, such as wool. The dye bonds with the protein fibers in the wool, which have 20 different amino acids, thus there are more ways for the dye to bond to the fabric and makes it more complex. Net equation: _NH2(fiber)+_HSO3(dye)>_NH3+_SO3 A colored compound that has a suitable group capable of forming a covalent bond between a carbon atom of the dye ion or molecule and (with cellulose fibers) the OH groups on the cellulose molecule. Chromophores absorb and reflect light; they make the dyes appear to be a certain color. Chemistry is the science of how different properties interact to create new substances; tie dye is an excellent example because it involves the bonding of molecules to create a new product. Dying garments that are not washable cannot be done because water is part of the chemical process Certain chemicals react with certain fibers. The three main/most common dyes are disperse, acid, and fiber reactive. Reaction - Soaking the t-shirt with sodium carbonate (Na2CO3) opens up bonding sites in the cotton fibers and raises the pH level, giving the dye molecules a place to bond. The hollow fibers let the dye molecules form bonds on the inside and outside Tie Dye


Transcript: In the 1960s to the 70's, tie dye was brought to America through the hippie movement, a youth movement that advocated the sexual revolution, psychedelic rock and protested the Vietnam War.

Mon. 20 May 2014. *Fabric Dye* *Popularity* The art of Tie dying has been around since 500-800 A.D the dyes were pigments from roots, leaves, flowers and berries. Peru and India created their own techniques involving dots, squares, waves and stripes, signifying wealth. Designs *60's Hippie Movement* Tie dye's popular start began in the 60's, reached its peak in the 1970's, and is still worn today. Considered more of an art than a actual style. Mix 2 cups water 1/4 cup white vinegar 1 package Kool Aide and put in a microwave safe bowl OR Mix 2 cups water 1/4 cup white vinegar A teaspoon of liquid food coloring H2O+ CH3CooH+ any food coloring+ NaCl For making dye Red food dye- C16H14N2Na208S2 Yellow dye- C16H9N4Na309S2 Blue dye- C37H34N2Na209S3 Step 1: Get a piece of fabric or shirt (ideally white cotton), coloured dye, elastic bands (number depending on the number of rings to create) and a small amount of soap. Set-up at a place with a water supply nearby (sink area). Step 2: Rinse the fabric in water and soap, then wring. Step 3: Pinch about 1 inch of the fabric at the center. Tie tightly with an elastic band. Step 4: Continue tying more elastic bands below each other, spacing about one inch apart. Tie ass many as you like. These with create circle patterns on the fabric. Step 5: Soak the fabric in the dye (and salt) and boiling water mixture as instructed on the pack. Step 6: Rinse well in clean water. The water from the squeeze fabric should run clear after wring the fabric. Step 7: Dry the fabric for 20 minutes. *Bibliography* *How to make Tie-Dye* Tie-dye can be used to create a wide variety designs on fabric, from standard patterns such as the spiral, peace sign, diamond, and the marble effect to beautiful works of art. *Video* *Chemical Equations* Clothing dye is neither an acid or a base but is commonly used with acids. Dye is a neutral pH *Background* Tie-Dye


Transcript: What did they first use? Where does tie-dye originate from? What ways can you tie-dye? Tie-Dye My research questions are: ~What did they first use? ~Where does tie-dye originate from? ~What ways can you tie-dye? Tie-Dying When they first started to figure out the system of dying, most people would just randomly fold, twist and tie up the fabric or clothing and dip it into the dye they used. But now a days, they have different materials you can use. One way is called "Lines" which uses rubber bands at intervals. Another is "Sunburst" which uses multiple marbles and rubber bands and the last is "Circles" which only uses one marble and one rubber band. Jennings, Julie A. "Tie-Dye through the Ages."

Bibliography "Sunburst" Tie-Dye originates from Japan and China. It started in China around 618-906 C.E which was during Tang Dynasty. It started in Japan around 552-794 C.E which was known as the Nara period. When people first started tie-dying, they didn't have the technology or materials we have today so the people had to use what was given to them. Some thing were: the juice from plants, flowers, leaves, bark, the juice from berries, roots and leaves (lichen, blackberry, onion, indigo, sage and marigold). They also used herb turmeric, what they did was they crushed it into a very fine powder and dissolved it in water so the fabric would be able to be soak up the deep yellow. This method was used in India for many years and was the start of art. The resits used wax, string and synthetic resits.
