Lesson 1 & 2 Flashcards
Fiber is
fabricated into a
YARN, or sometimes
drectly into fabric.
Staple fiber
is combed,
cleaned, and aligned to
make long lengths that
can be woven or
knitted
Fabric manufacturers
different ways and techniques to make products
Textiles must
abide with the design elements
Types of fiber manufacturers:
Manufactured
fibers producers-
Natural fibers

SPINNING
is the process of drawing out and imparting twist to a mass of fibers.
Filament yarns generally require
less twist than staple
A fairly high degree of twist
produces
strong yarn.
low twist produces
softer, more lustrous yarn
tight twist
produces
crepe yarns
Two or more single strands of yarn may be twisted together
forming ply yarn
Drawing, also called Drafting, in yarn manufacture, is
a process of attenuating the
loose assemblage of fibers called sliver by passing it through a series of rollers, thus
straightening the individual fibers and making them more parallel.
Drawing reduces
a soft mass of fiber to a firm uniform strand of usable size.
In the
production of man-made fibers,
drawing is a stretching process applied to fibers in
the plastic state, increasing orientation and reducing size.
