Weaving Traditions of Ethiopia Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
History of Weaving Passed on for many generations Weaving communities within cities and towns Sheromena, Addis Ababa Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
The Process of Weaving Cotton is obtained from cotton plants or purchased from growers Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
The Process of Weaving Cotton is spun into thread by women using a wooden spooling tool called a ___________ Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
The Process of Weaving Spun cotton is then washed, dyed, and hung out to dry Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
History of Dyeing Natural Dyes throughout the world: -Extracts from flowers, animals, barks, roots, dry woods, fruit, leaves, etc -Red: madder root, cochineal beetles -Yellow: goldenrod, onion skin -Blue: indigo, red cabbage -Brown: black walnuts Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
History of Dyeing Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
Chemistry of Dyeing - Some dyes just stain thread, so it continues to wash out - Other dyes chemically attach to molecules of the fabric and can never be washed out Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
Chemistry of Dyeing - Cotton- long strands of cellulose molecules, twisted together Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
Chemistry of Dyeing - So how do we get the dye molecules and the cotton cellulose molecules to stick together? Mordant Metal ions Urine Alum (potassium aluminum sulfate) Salts- sodium, chromium, copper, iron, tin, iodine Tannic acid Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
Chemistry of Dyeing Mordanting A process where a mordant firmly attaches to cotton fibers and then binds the dye molecules Effects the color: Iron (II) - brown Aluminum- red Tin (II) – pink Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
Chemistry of Dyeing Mordanting Dye molecule attaches to a mordant which then binds to the wool fiber (opposite charges) Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
Chemistry of Dyeing Visible color Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
Chemistry of Dyeing Ethiopian natural dyeing - Extracts from locally grown vegetables Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
Hand-made Natural Dyes! Today, you and your group members will be working to create your own natural dyes. Each group will be dyeing wool yarn Groups of 3-4 Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
Materials Wool yarn Hot plate H 2 O Beaker NaCl Vegetable/fruit- red cabbage leaves, yellow onion skin, blackberries, raspberries Plastic knife Tongs Drying rack Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
Safety Be careful with Hot plate- use tongs & gloves Be careful with Plant dye- stains Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
Catalyst 11/12/09 What is necessary to make dyes bind permanently with clothe fibers? HOMEWORK: Finish weaving placemat N Mordents- metal salts Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
Post Dyeing Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
The Process of Weaving Once dried, the thread is spun onto large spools manually by the men Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
The Process of Weaving Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
The Process of Weaving Yarn is then turned on a machine into smaller spools to be used during actual weaving Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
The Process of Weaving Using a loom, sometimes dug into the ground, men can weave scarves, blankets, dresses, etc Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
Ethiopian clothing Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
Ethiopian Weaving Using our dyed yarn from yesterday and a 12” cardboard loom we will create our very own Ethiopian-inspired placemats Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
Ethiopian Weaving Materials -Cardboard loom -Warp thread -Pre-dyed Yarn -Plastic needle Created by: Meghan Chidsey, Teaching the Human Experience Ethiopia 2009
Making the Loom- Warp -Tie note 6” down from end of string -Hook through first cut and thread string up and down, keeping it only on one side of the board -At the end, tie string with the beginning on the back of the board -SEE FOR EXAMPLE!
