Manufactured Fabrics are usually made of filaments extruded
as liquid and formed into various fibers. Because the fiber starts as a liquid, many of
the fibers are colored before they become filament, thus they are difficult to dye after
the fiber is woven into a fabric.
ACETATE is not a strong fiber but can be
extruded into fibers of different diameter and woven into fabrics that have the luxurious
look of silk but do not wear like silk. Acetate does not absorb moisture readily but dries
fast and resists shrinking. This is a resilient fabric that resists wrinkling in addition
to being pliable and soft with a good drape. Triacetate is an improved acetate fabric
which doesnt melt as easier and is easier to care for. Remember, acetate in nail
polish and nail polish remover will melt acetate as will alcohol so take care with
perfumes and nail products including SuperGlue.
ACRYLIC is a fine soft and luxurious
fabric with the bulk and hand of wool. Light weight and springy, this fabric is
non-allergenic, dries quickly, draws moisture away from the body and is washable. Acrylic
does not take even a moderate amount of heat. Modacrylics are used in pile fabrics like
fake fur and are more flame resistant.
LASTEX is an elastic fiber made from
Latex. It is most often used with other fibers to create fabrics such as Spandex and
foundation garments. Lastex will deteriorate after repeated washing and drying, losing its
elasticity.
NYLON became a household word in 1940 when
it was knitted into hosiery. In 1942 it was called into service for the armed forces use
in parachutes, flak vests, combat uniforms, tires and many other vital military uses.
Until the war was over nylon was not available to the public. Nylon became one of the most
versatile fibers of the man-made fabrics. In addition to hosiery, nylon is used in tricot,
netting for bridal veils, and in carpeting.
Nylon is stronger yet weighs less than any other commonly
used fiber. It is elastic and resilient and responsive to heat setting. Nylon fibers are
smooth, non-absorbent and dry quickly. Dirt doesnt cling to this smooth fiber nor is
it weakened by chemicals and perspiration. Extensive washing and drying in an automatic
dryer can eventually cause piling. Nylon whites should be washed separately to avoid
graying. This fabric may yellow so it should be bleached frequently with sodium perborate
bleach.
Nylon melts at high temperatures. If ironing is necessary,
always use a low temperature on the wrong side.
POLYESTER is a strong fiber that is
resistant to crease and thus keeps it shape. Polyester melts at medium to high
temperatures. Although many people dislike polyester, perhaps due to the double knit fad of
the 1950, polyester remains a versatile and important man-made fabric. Blends of polyester
give cotton a permanent press property and extend the wear of these blended garments.
Polyester is manufactured in many weights including
fiber-fill used in pillows and upholstery. Threads spun from polyester fibers are strong,
wear exceptionally well, and are used extensively in home sewing and manufactured sewing.
RAYON, from cellulose, has many of the qualities of cotton, a natural cellulose fiber. Rayon is strong, extremely absorbent, comes in a variety of qualities and weights, and can be made to resemble natural fabrics. Rayon does not melt but burns at high temperatures.
Rayon drapes well, has a soft, silky hand, and has a smooth, napped, or bulky surface. Rayon will wrinkle easily and may stretch when wet and shrink when washed.
Technological advancemnts to the rayon process have produced high wet modulus [HWM] rayons such as lyocell and modal which makes fabric less prone to stretch when damp or wet.
Washable rayon will state the care on the fabric label. Like silk, if you pre-wash rayon fabric prior to construction of the garment, you have a washable garment.
Glossary of Rayon Fabrics
Fibranne is French term for Viscose rayon.
Velvet, although made from silk, is most
often produced from the rayon fiber.
SPANDEX is an elastic type fiber that can
be stretched many times its length and then spring back to the original length. Spandex is
more resistant to washing, perspiration, and heat than latex. Spandex is used in
foundation garments and hosiery.
