Modernization efforts have brought major changes to the U.S.
textile industry. Equipment has been
streamlined and many operations have been fully automated with
computers. Machine speeds have greatly
increased. At most mills the opening of cotton bales is fully
automated. Lint from several bales is mixed and
blended together to provide a uniform blend of fiber properties. To
ensure that the new high-speed
automated feeding equipment performs at peak efficiency and that
fiber properties are consistent,
computers group the bales for production/feeding according to fiber
properties. The blended lint is blown by
air from the feeder through chutes to cleaning and carding machines
that separate and align the fibers into
a thin web. Carding machines can process cotton in excess of 100
pounds per hour. The web of fibers at
the front of the card is then drawn through a funnel-shaped device
called a trumpet, providing a soft, rope-
like strand called a sliver (pronounced SLY-ver). As many as eight
strands of sliver are blended together in
the drawing process. Drawing speeds have increased tremendously
over the past few years and now can
exceed 1,500 feet per minute. Roving frames draw or draft the
slivers out even more thinly and add a gentle
twist as the first step in ring spinning of yarn. Ring spinning
machines further draw the roving and add twist
making it tighter and thinner until it reaches the yarn thickness
or count” needed for weaving or knitting
fabric. The yarns can be twisted many times per inch. Ring spinning
frames continue to play a role in this
country, but open-end spinning, with rotors that can spin five to
six times as fast as a ring spinning machine,
are becoming more widespread. In open-end spinning, yarn is
produced directly from sliver. The roving
process is eliminated. Other spinning systems have also eliminated
the need for roving, as well as
addressing the key limitation of both ring and open-end spinning,
which is mechanical twisting. These
systems, air jet and Vortex, use compressed air currents to
stabilize the yarn. By removing the mechanical
twisting methods, air jet and Vortex are faster and more productive
than any other short-staple spinning
system. After spinning, the yarns are tightly wound around bobbins
or tubes and are ready for fabric
forming. Ply yarns are two or more single yarns twisted together.
Cord is plied yarn twisted together.
