_Classes of Weave_

7. How many classes of weave have been studied?

8. Name the classes of weave.

9. Name a fabric to illustrate each weave.

=Experiment 7--Fibers=

Apparatus: Pick glass, dissecting needle.

Materials: Samples of broadcloth, mohair, silk, cotton cloth,
linen.

References: _Textiles_, pages 1; 97, Mohair; 203, Silk; 105,
Cotton; 193, Linen; 199, Hemp; 201, Jute; 232, Ramie; 233,
Pineapple.

_Directions_

1. Read _Textiles_, page 1, paragraph 1. What are textiles?

2. Cloth is composed of yarn. Yarn in its turn is composed of many
small ends called fibers.

3. Look at the sample of broadcloth. If you did not know this to be
broadcloth you would speak of it as woolen goods. Detach from the
sample a filling thread and separate it into fibers. These are woolen
fibers.

4. Examine the sample of mohair and separate a filling thread into
fibers. This takes the name mohair from the fibers which compose it.
Mohair is obtained from the Angora goat.

5. Examine a sample of silk, also a detached filling thread. The silk
fiber consists of a thread spun by the silk worm.

6. Wool, mohair, and silk fibers are obtained from the animals, the
sheep, goat, and silk worm, hence they are called animal fibers.

7. Detach from the sample of cotton cloth a filling thread and
separate it into fibers. These are cotton fibers and are obtained from
the cotton plant.

8. Examine the sample of linen, a filling thread and its fibers. Linen
is composed of fibers obtained from the flax plant.

9. Cotton and linen fibers are obtained from plants, and are called
vegetable fibers. There are other vegetable fibers such as jute, hemp,
ramie, pineapple, etc., but cotton and linen are the most important.

10. Name the most valuable fibers for textile use.
