_Satin Weave_

1. Examine the sample of satin under the pick glass. Notice that the
warp and filling interlace in such a way that there is no trace of the
diagonal on the face of the cloth.

_a._ Is satin of a close or loose weave?

_b._ What can you say of the surface of satin?

_c._ What effect has this smooth surface on light?

_d._ This is called a satin weave. Why?

_e._ What is the most extensive use of the satin weave?
(See _Textiles_, page 1.)

NOTE.--Sometimes fabrics of other weaves will have a satin stripe.

_Gauze Weave_

2. Examine the sample of voile under the pick glass. This is a type of
what is known as gauze weave.

_a._ What is the chief characteristic of the gauze
weave?

_b._ Name several gauze fabrics.

_Lappet Weave_

3. Examine a piece of lace curtaining under the pick glass.

_a._ If the fancy figures were not present, of what
weave would this sample be?

Simple figures are stitched into plainly woven or gauze
fabrics by machinery to imitate embroidery. This style
of weave is known as lappet weave.

_b._ On fabrics of what two weaves is lappet weaving
used?

_c._ What is lappet weaving?

_Jacquard Weave_

4. Examine a piece of carpet. Notice the elaborate designs or patterns
and the number of colors used. When the figures are elaborate they
cannot be stitched in by simple lappet weaving. A special attachment
called the _Jacquard_ apparatus is placed on top of the loom. This
apparatus controls the warp threads so that a great many sheds may be
formed and elaborate figures woven into fabrics. This is called
Jacquard weaving.

_a._ What must be added to a loom for Jacquard weaving?

_b._ What is the use of the Jacquard apparatus?

_c._ When is the Jacquard weave used instead of lappet
weave?

In this way they are fastened together securely.

_a._ What color is the sample on one side? the other?

_b._ Of what is double cloth composed?

_c._ How are the single cloths combined into one?

_d._ Read _Textiles_, page 62. What are some of the uses
