== Description ==
+
Fibers manufactured from substances that have been produced or modified by chemical reactions. Artificial fibers were first made in 1842 when molten glass was formed into filaments. By the late 1880s, man-made fabrics were being made from [[cellulose%20nitrate|Cellulose nitrate]] and [[rayon%20fiber|Rayon]] fibers. Current examples include: [[acetate%20fiber|Acetate]], [[acrylic%20fiber|Acrylic]], [[alginic%20fiber|Alginic]], [[anidex%20fiber|Anidex]], [[aramid%20fiber|Aramid]], [[azlon%20fiber|Azlon]], [[casein%20fiber|Casein]], [[cupro%20fiber|Cupro]], [[nylon%20fiber|Nylon]], [[novoloid%20fiber|Novoloid]], [[nytril%20fiber|Nytril]], [[modacrylic%20fiber|Modacrylic]], [[modal%20fiber|Modal]], [[olefin%20fiber|Olefin]], [[polyester%20fiber|Polyester]], [[Polyethylene fiber|Polyethylene]], [[Polypropylene fiber|Polypropylene]], [[saran%20fiber|Saran]], [[spandex%20fiber|Spandex]], [[sulfar|Sulfar]], [[triacetate%20fiber|Triacetate]], [[vinal%20fiber|Vinal]], and [[vinyon%20fiber|Vinyon]].

Synthetic fibers dress
MFA# 1998.37

Description

MFA Acc. #: L-R 27.2008

Fibers manufactured from substances that have been produced or modified by chemical reactions. Artificial fibers were first made in 1842 when molten glass was formed into filaments. By the late 1880s, man-made fabrics were being made from Cellulose nitrate and Rayon fibers. Current examples include: Acetate, Acrylic, Alginic, Anidex, Aramid, Azlon, Casein, Cupro, Nylon, Novoloid, Nytril, Modacrylic, Modal, Olefin, Polyester, Polyethylene, Polypropylene, Saran, Spandex, Sulfar, Triacetate, Vinal, and Vinyon.

Properties of Synthetic Fibers (Part 2)

Fiber Degradation Dyes used Microscopic characteristics Applications
acetate Degrades in acids and concentrated alkalis disperse irregular cross section with multiple lobes; lengthwise striations coats, suits, linings, cigarette filters
acrylic Susceptible to heat; accumulates static charge basic, disperse, pigment variable cross section subsitute for wool in coats, sweaters, hosiery, blankets, filters
aramid (meta) Degraded by acids, alkalis, oxidizing agents and UV light fiber is smooth; cross section is dogbone filter bags for hot stack gases, flame-resistant clothing
aramid (para) Degraded by acids, alkalis, oxidizing agents and UV light fiber is smooth, cross section is circular radial tires belts, bulletproof vests, resin reinforcements
azlon Degraded by alkalis; weak when wet; susceptible to microbiological growths diameter=20-30 microns, cross section is circular or bean-shaped, filament is smooth silk substitute
modacrylic Resistant to alkalis and acids flame-resistant clothing, artificial fur, children's sleepwear, tents
nylon 6 Degraded by concentrated acids and phenol; resistant to alkalis and most organic solvents acid, disperse, mordant, pigment, reactive fiber is smooth, cross section is circular hosiery, lingerie, sports garments, upholstery
nylon 6,6 Degraded by concentrated acids and phenol; resistant to alkalis and most organic solvents acid, disperse, mordant, pigment, reactive fiber is smooth, cross section is circular or trilobal tires, ropes, seat belts, parachutes, fishing lines and nets; surgical sutures; brushes
nytril Resistant to sunlight, oxidation and insects. opaque, white with flattened or hook-shaped cross section sweaters, pile fabrics, in wool blends
polyester Degrades in strong acids, strong alkalis and creson. disperse, pigment smooth fibers; cross section may be circular, trilobal or polygon permanent press clothing, fiberfill, carpets, sewing thread, seat belts, yarns, nonwoven fabrics
polyethylene Resistant to acids, alkalis and bleaches; dissolves in dry-cleaning solvents, degrades slowly in sunlight basic, disperse pigments cross section is circular or elliptical cordage, webbing; upholstery, outdoor applications
polypropylene Resistant to strong acids and alkalis; resistant to biodeterioration basic, disperse pigments cross section is circular or elliptical upholstery, carpets, ropes, nets, disposable nonwoven fabrics
polyurethane Chlorine causes slow degradation acid, disperse, reactive, vat elastomeric fabrics; swimwere; althletic clothes
polyvinyl chloride Soluble in chlorinated and aromatic solvents; degrades with heat and light basic,
disperse, pigment 		irregular cross section elastomeric fabrics; outdoor fabrics (tents, awnings, rain gear etc)
rayon (cupro) Degrades in strong alkalis, acids and undiluted bleaches. Resistant to dry cleaning solvents circular cross section with no striations sheer fabrics and netting; lightbulb filaments
rayon (viscose) Degrades in strong alkalis, acids and undiluted bleaches. Resistant to dry cleaning solvents direct lengthwise striations; early samples have circular cross sections with serrations, later samples may be dog-boned or trilobal rugs, cotton substitute, nonwoven fabrics, paper (cellophane)
vinal Resistant to microorganisms, insects, and most chemicals. fibers are smooth; cross section is round, ben-shaped or u-shaped raincoats, jackets, umbrellas, tarps, fishnets, awnings.

Fiber Burn Tests

Fiber Appearance Odor Residue
Natural fibers
Cotton Burns very fast with a bright yellow flame, similar to paper burnt paper burnt ends look bushy
Linen Burns very fast with a bright yellow flame, similar to paper burnt paper burnt ends appear melted together
Silk Burns and bubbles faster than wool with a yellow flame burnt hair (mild) black, brittle, spherical beads
Weighted silk Does not burn; the fabric will char burnt hair (faint) fabric retains shape
Wool Burns slowly; bubbles while burning; easy to put out flame burnt hair (strong) black, brittle, irregular beads
Synthetic fibers
Acrylic Burns readily with smoky flame acidic hard ash
Aramid Does not burn
Cellulose acetate Burns fast with a yellow flame; may melt and sputter burnt paper hard, black beads; similar to silk
Modacrylic Self-extinguishing
Nylon Melts first, then ignites and burns rapidly. burnt plastic
Polyester Difficult to ignite, self-extinguishing. Burns with shiny, yellow-orange, sooty flame. sweet hard ash
Polyethylene Burns with a heavy, sooty, waxy smoke. Softens at 120 C.
Polypropylene Burns with a heavy, sooty, waxy smoke.
