hat remain without appreciable alteration for a month of exposure to
direct summer sunlight are classified as "fast," and those undergoing
slight appreciable change under the same conditions as "fairly fast."
"Moderately fast" colors are those altering considerably in fourteen
days; and those more or less completely faded in the same time
(fourteen days) are designated as "fleeting."
=Directions for testing fastness of Color in Sunlight.= Cover one end
of the sample of cloth with a piece of cardboard. Expose the fabric to
the sunlight for a number of days and examine the cloth each day in
the dark and notice whether the part exposed has changed in color when
compared with the part covered. Count the number of days it has taken
the sunlight to change the color.
Brown in woolen materials is likely to fade. Brown holds
its color in all gingham materials.
Dark blue is an excellent color for woolens and
ginghams. Light blues on the other hand usually change.
Black, gray, and black with white. These colors are very
satisfactory for woolen materials.
Black is not a color which wears very well with cotton
fabrics, as it shows the starch (sizing) and often
fades.
Red is an excellent color for all woolen materials. It
looks attractive and wears well.
Red is a very poor color for cotton. It loses its
brilliancy and frequent washing spoils it.
A deep pink is an excellent color for all ginghams for
it fades evenly and leaves a pretty shade.
Green is a poor color for both cotton and woolen
materials unless it is high priced.
Lavender fades more than any other color in textiles.
HISTORY OF TEXTILES
The three fundamental industries that have developed from necessity
are the feeding, sheltering, and clothing of the human race. These
primary wants were first gratified before such conveniences as
transportation and various lines of manufacture were even considered.
Next to furnishing our food supply, the industry of supplying clothing
is the oldest and the most widely diffused. It is in the manufacture
of textiles--including all materials used in the manufacturing of
clothing--that human ingenuity is best illustrated.
The magnitude of the textile industry in the United States is evident
when we consider that it gives employment to a round million of
people, paying them nearly five hundred million dollars annually in
wages and salaries,
