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, 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

polyvinyl chloride Soluble in chlorinated and aromatic solvents; degrades with heat and light basic,
disperse, pigment

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
