13. For what two processes is wool now ready?
Experiment 16—Raw Wool to Yarn
Apparatus: Hand cards, coarse and fine combs, pencil.
Material: Scoured wool.
Reference: The preceding experiments.
Directions
1. This wool has already been subjected to the three operations of shearing, scouring, and oiling.
2. Card the wool. What does carding do to the wool?
3. Strip the cards. Rub the sheet of fibers between the palms of the hands into the form of a strand. It is in this form that it leaves the card of the mill, and it is known as a sliver of wool.
4. Pull about three inches of wool from the sliver and perform upon it the operation of gilling by combing it with the coarse comb.
5. Follow the gilling by the operation of combing, which you will do by combing again, this time with a fine comb.
6. Pull about three inches again from the sliver. Continue to gill and comb by section until the entire sliver has been gilled and combed.
